How Often Should You Schedule Your Home HVAC Service?

Many homeowners are rather casual when it comes to preventative maintenance on their HVAC system. All too many homeowners tend to wait until there is trouble before calling for a checkup. That's not necessarily the best way to keep your HVAC running right. With a piece of equipment as expensive as your HVAC, you want to catch little problems before they become big problems.

Let's have a look at what the industry recommends when it comes to HVAC service.

Spring and Fall HVAC Service

Most experts recommend twice-yearly visits from the HVAC technician. In spring, we call for maintenance on the air conditioner; in fall, we call for maintenance on the heating equipment. We want to be sure that any potential problems are discovered before the triple-digit days of summer arrive or we're plunged into the frigid depths of winter storms. The last thing you want is a failed HVAC system in the middle of a serious weather event.

Other Benefits of Preventative HVAC Service

Besides circumventing breakdowns, there are other benefits of preventative maintenance. The most obvious is that you can keep your equipment running in good order for years, extending its life beyond your best expectations. Should you decide to sell your house, you will also have a track record that shows that your HVAC equipment has been well maintained. So, even if it's older, you have the benefit of showing you've been conscientious about keeping it up to speed.

Furthermore, your HVAC system will run more efficiently when it's well maintained. Without regular maintenance, you may be missing out on minor repairs that could bring you greater efficiency and less energy usage.

Maintenance Checklist

In spring, your HVAC consultant will do the following:

• Clean evaporator and condenser coils 

• Check the refrigerant level

• Inspect and tighten electrical connections

• Examine the condensate drain and pan

• Calibrate the thermostat

• Clean and fine-tune the air handler and blower for adequate airflow

In fall, the HVAC consultant will do the following:

• Change filter

• Clean burners

• Check the gas line

• Clean the air handler

• Check the thermostat

• Inspect heat exchanger

What Are the Top HVAC Energy Wasters in Your Home?

Do rising electricity costs make you dread opening your monthly power bill? The biggest consumer of energy in your home is your HVAC system, so if you want to save money, that's the place to start. Fortunately, there are a few simple changes that can help enormously. Here are some of the top HVAC energy wasters in your home and what to do about them.

• Clogged air filter. As dust builds up in your filter, it's harder for air to get through it. Thus, the system has to work harder and run longer, running up your energy bill. Check the filter monthly and replace it regularly to keep air flowing properly. You can also keep it from getting clogged quickly by dusting and vacuuming your home regularly to reduce dirt and other contaminants and, in turn, limit one of the top HVAC energy wasters.

• Leaky ducts. It doesn't matter how well air flows through your system if that same air is still leaking out before it can reach your home. Pinhole leaks in your ductwork can cause energy losses of up to 30%, making them one of the top HVAC energy wasters. Look for leaks, holes, and other ductwork issues and seal them up with metal tape or mastic sealant (not duct tape).

• Thermostat settings. The lower your AC setting and the higher your furnace temperatures, the more energy you use. Turning the thermostat up or down a few degrees can make a world of difference. It's recommended you set your thermostat at 78 degrees in summer and 68 degrees in winter to balance comfort and energy usage.

• Thermostat programming. A programmable thermostat is one of the best tools for energy savings. Turning your HVAC system off entirely when you leave the house results in extreme temperatures and a lot more energy spent getting your home back to your comfort setting. A programmable thermostat lets you turn the temperature up or down a few degrees when you leave home or when you return, saving money and energy.

How Can Pet Hair Affect Your HVAC Unit’s Efficiency?

Pets are an essential part of the family, and we simply can't live without them. What we could live without, however, is the pet hair. Today, we're going to discuss how fur and dander can affect your HVAC system and what should be done about it.

How Does Pet Hair Affect Your HVAC’s Efficiency?

You don't have to own a pet for very long to realize that fur and dander get everywhere. Pet fur and dander that gets into your HVAC system's air filter will clog it up and make it harder for your equipment to operate efficiently. This can cost you money in utility bills and lower the operational life span of the system.

Best Ways to Deal with Pet Fur and Dander

Pet fur and dander may wreak havoc with your HVAC equipment, but it's definitely something that can be controlled. Here are some quick tips:

Vacuum Each Week

One of the most obvious things you can do to reduce the amount of pet fur and dander is to vacuum your floor each week. Carpets are the most obvious, but tile and wood can be vacuumed as well. If not, grab a broom and start sweeping.

Install a New Air Filter

The general rule about either cleaning or replacing your air filter is to do so every two to three months. But, if you have a pet, you might want to check the filter every couple of weeks and replace it more often. You might also want to invest in a higher-quality filter so that it can trap more debris before needing to be replaced or cleaned.

Clean Your Pets Daily

Your dog or cat might not like the idea of you grooming them every day, but it needs to be done to comb pet hair. Get a high-quality brush and use it at least once a day, especially if you have a long-haired breed. And don't forget to give them a bath every week or so.

Do You Know the HVAC Science Behind How Your Unit Works?

Few things can be more refreshing in the summer than the blast of cool air from your HVAC unit. But do you know how much effort goes into delivering that cool air to your Northeastern Oklahoma home? When you understand the basic HVAC science behind how your air-conditioning system works, you'll appreciate the system more and take better care of it, lowering the need for AC repairs and prolonging its longevity.

The HVAC Science Behind How HVAC Units Work

AC units utilize refrigerant to cool your home. The refrigerant continuously changes between liquid and gaseous states within your AC coils. It moves from inside to outside your home and back again, extracting heat from your home's air and transferring it outside in the process.

Your air conditioner draws room-temperature air in through your return registers to cool it. The air passes through the air filter, which captures dirt and debris to protect delicate AC components. Fans blow the air across the evaporator coil inside your home, which contains cold liquid refrigerant. The refrigerant absorbs heat from the air and evaporates to vapor, whereas the air concurrently becomes colder after having its heat removed.

The blower circulates the cooled air through your ducts and supply registers into your home. The vaporized refrigerant, on the other hand, flows outside your home into the compressor. Here, the refrigerant is pressurized and heated further to prepare it to release its heat to the outdoor air.

The hot pressurized refrigerant then moves into the condenser, where it condenses into a liquid as the heat absorbed from inside your house radiates away. Outdoor AC units usually have metal fins and a large fan to quicken the heat dissipation. The refrigerant then flows back inside through an expansion valve that depressurizes it, causing its temperature to drop significantly. At this point, the refrigerant is ready to start the cooling cycle again, all thanks to HVAC science doing its thing.

As you can see from the HVAC science behind air conditioners, a number of components and processes are involved in cooling your home. Therefore, ensure you carry out the necessary AC maintenance steps, such as changing your air filter regularly and scheduling annual maintenance, to keep your system operating properly. Contact us at Air Assurance for all your HVAC installation, repair, and maintenance needs in the Broken Arrow area.

Can HVAC Condensation Harm Your Unit in Hot Weather?

As your air conditioner cools, it also removes moisture from your home's air, collecting it as HVAC condensation on the coils and then expelling it from the home via a drain line. During routine maintenance, your HVAC tech will explain why it's important that HVAC condensation be properly removed from your home. Otherwise, excessive HVAC condensation can cause major damage not only to your HVAC unit but also to your home. 

Causes of Condensation Problems

1. Copper Pipes Sweating. The copper pipes that form the AC suction line must be covered with black insulation known as Rubatex pipe insulation. If this insulation is torn or somehow doesn't cover the suction line, the pipes will sweat. The line must have a sealed vapor barrier to work correctly.
   

2. Ductwork Needs a Vapor Barrier. This refers to the insulation around the ductwork that connects the supply air to the air handler. This so-called "transition" needs a vapor barrier to work properly.
   

3. The Condensation Drain Pan Is Clogged or Has a Hole. This is the system through which the condensation drains away. It should be checked yearly for holes or clogs in the drain or other obstructions in the pan. The HVAC tech may use bleach or some other treatment to ensure that the drain line is clear. A clog can cause the pan to overflow, resulting in water damage. Also, the AC will not cool the home properly if the line is clogged. 
   

4. Dirty Air Filter. Changing the air filter as often as recommended, or whenever it's dirty, is key to the optimum performance of your AC. If the filter is clogged, it will slow down the movement of air in the equipment and the AC will not cool properly. In addition, there will be more wear on the HVAC parts and a higher likelihood of a breakdown.
   

5. Drain Slope. Construction projects can shift things around on your property. For instance, the air handler might be lower than the drain line. The line should downslope away from the air handler.

How Can Geothermal Energy Help Your Home's HVAC System?

The most efficient type of HVAC system is a geothermal heat pump. They're not practical for everyone, but if you're able, there's no better way to heat or cool your home. Read on to learn how geothermal energy works.

Geothermal Energy

No matter how hot or cold the weather gets, the temperature about 10 feet below ground remains constant at 54 degrees. A geothermal heat pump uses that energy to heat or cool the air circulating through your home.

A loop of pipe, called a heat exchanger, is buried underground, and water or another liquid circulates through it. In winter, when the temperature below ground is warmer than the surface temperature, the liquid absorbs that heat and uses it to warm the air. Your regular heating system then warms the air the rest of the way, using much less energy than it would take to heat the freezing winter air directly.

In summer, it works the other way. The system absorbs heat from your home and uses the heat exchanger to transfer it into the ground. The cool water in the pipes then cools the air that circulates through your home.

Types of Geothermal Heat Pumps and Geothermal Energy

There are four types of geothermal heat pump. Most common is a horizontal system, where the pipe is buried 10 feet below ground in a loop around your property. If there's not enough room on the property for the pipes to spread, a vertical system can be used instead, meaning the pipes are buried straight down, between 100 and 500 feet below ground.

If your house is near a body of water, you can install a less-expensive lake-source heat pump. Instead of going underground, the pipes run to the bottom of the lake, at least 8 feet beneath the surface, and the system functions the same way. Finally, an open-source heat pump can collect water from a well, loop it through the system, then deposit it back into the well.

How to Smartly Shop for a New HVAC Unit This Summer

HVAC systems are built to last for more than a decade — sometimes as long as 20 years or even longer — but they'll eventually need to be replaced. If you're in the market for a new HVAC unit, you've come to the right place. Observe the following tips for purchasing a new system and you can't go wrong.

Find the Right Size for Your Home

The last thing you want to do is install an HVAC system that isn't the right size for your home. If you're unsure of how to figure out what size your new HVAC unit should be, don't hesitate to seek the advice of a professional. You definitely don't want to get this wrong, because an incorrectly sized system will lead to energy waste, large utility bills, and an uncomfortable household.

Pick an Energy-Efficient Model

Even if you're not the type of homeowner who's constantly looking for ways to "go green," you should definitely consider purchasing the most energy-efficient HVAC unit you can afford. A system with a SEER rating of 15 or above will save you on your energy bills every month. The system will cost you more initially, but it will be worth it in the long run due to lower energy costs.

Pair with a Smart Thermostat

Modern HVAC systems work very well with programmable and smart thermostats. By pairing them together, you can help ensure that you're saving energy and money whenever possible. If you're not already using a smart thermostat, we'd suggest that you upgrade your thermostat at the same time that you install a new HVAC unit.

Choose a Respected Contractor

First and foremost, you never want to install an HVAC system yourself. You need to find a respected HVAC contractor who has experience with installation. This way, the work will be guaranteed so that you don't have to worry about anything going wrong. They'll also help ensure that you've selected the right unit for your home's needs.

The Five Most Important HVAC Questions for Your Tech

The summer season is almost upon us, which means you're likely to have an appointment with your HVAC technician soon. While the technician is in your home, don't forget to ask these five important HVAC questions:

What Kind of Services Do You Provide?

The title of HVAC technician can be a bit broad, so one of the most important HVAC questions you can ask is exactly what type of services they provide. The company may stick primarily to traditional heating and cooling systems, but many have extended that to mean heat pumps, ductless mini-splits, solar power, geothermal power, etc. It's important that you know their specialties before hiring them.

How Much of the System Will You Check?

No matter what type of HVAC system is being inspected, there are many parts involved. One of the most important HVAC questions you can ask the technician is whether they'll be inspecting components such as the system's thermostat, ducts, registers, vents, outdoor units, UV lights, and anything else that's been installed or is part of the system. They may offer partial or full inspections.

Will You Provide Everything in Writing?

One thing you learn when dealing with any type of professional service is that it's important to always get everything in writing. Any reputable HVAC company will have no problem providing you with documentation of any estimate, warranties, certification, etc. 

How Can I Reduce My Monthly Utility Bills?

Due to rising costs, everyone is scrambling to reduce their monthly utility bills. Since HVAC technicians work with heating and cooling units every day, they can give you tips based on your home's layout and the current state of your equipment. Be sure to ask for their advice during the next house call.

How Can I Improve My Indoor Air Quality?

Another thing that an HVAC technician can help you with is your indoor air quality. A good technician will be aware of all the best equipment and devices on the market that will help you keep your air clean. They'll be able to provide you with some decent options.

Learn How BTUs Work Inside Your Home's HVAC System

When you're in the market for a new HVAC system, you'll encounter the abbreviation "BTU." Understanding this term is crucial to ensuring that you get the right HVAC system for your home's comfort and energy-efficiency needs. Read on to learn more about how BTUs work.

What Is BTU?

BTU, or British Thermal Unit, is a heat-energy measurement. A BTU is equal to the energy used to heat 1 pound of water by 1 degree. A BTU is relatively small. However, the BTU rating of appliances such as HVAC systems is in the thousands. For example, a furnace may be rated at 100,000 BTU.

BTUs help reveal the performance of an HVAC system. The BTU rating of HVAC equipment indicates the amount of energy a furnace or heat pump uses to generate heat or an air-conditioning system uses to absorb heat from your home's air and take it outside.

The Right BTUs for Your HVAC System

BTU helps you determine the type of HVAC system you need for your home. Getting an HVAC system without considering its BTU rating can significantly downgrade your comfort and increase energy bills. The square footage of the space to be heated or cooled is a key consideration in choosing the correct BTU rating.

Getting an HVAC system with too many BTUs for a house your size will lead to the equipment short-cycling and wasting energy. Short cycling can damage the equipment and shorten its life span.

Due to how BTUs work, HVAC equipment with too few BTUs for your space also presents its own set of problems. The equipment won't have enough cooling or heating capacity to cool or heat your home effectively. Besides causing comfort problems, the equipment may run nonstop as it strains to serve your indoor spaces, costing you more in utility bills.

Based on how BTUs work, it's essential that you get an HVAC system with the BTUs that your home needs. A local HVAC professional will assess your home and give you accurate, expert recommendations. If you need quality HVAC installation, repair, or maintenance services in the Broken Arrow area or want to learn more about how BTUs work, don't hesitate to contact us at Air Assurance for assistance.

Is It Wise to Get a Secondhand HVAC Unit for Your Home?

We've all saved money by buying something secondhand. The question is whether or not the savings is worth it. Here, let's take a look at what you should consider when deciding whether or not to purchase secondhand HVAC equipment.

Find Out Info About the Equipment

When you purchase a new HVAC system, you're obviously going to know a lot about it because of  the manufacturer details, Energy Star label, etc. With a secondhand system, you need to know certain details such as how old it is, how many repairs it's been through, its average energy usage, etc. This will give you a good idea of how long it will last and how well it will work.

Check to Make Sure the Secondhand HVAC Is the Right Size

Some homeowners will purchase HVAC equipment that's not quite the right size for their home because it's a great deal. Trust us when we tell you that this is a mistake. A wrongly sized HVAC system will either not be big enough to cool your home or it will produce too much moisture because it's cycling off too frequently due to being oversized.

Figure Out Who Will Install the Secondhand HVAC

If you decide to purchase a secondhand system, you need to figure out who's going to install it. Professional HVAC installers may not agree to do the job because they can't guarantee that the system will work. This could leave you with a general contractor, a friend, or yourself,  all of which risk improper installation.

Decide If Saving a Few Bucks Is Worth It

You really need to decide if saving a few bucks on a secondhand unit is worth the hassle. Yes, a brand-new HVAC system can be quite expensive, but it will last you a very long time. The risks of a secondhand piece of equipment just might not be worth it in the end.

If you have any questions about purchasing a secondhand HVAC system or would like to set up an appointment, contact the friendly professionals at Air Assurance today. We've been serving the Broken Arrow area since 1985.

Warm Weather HVAC Tips to Know as Summer Approaches

It's warming up in Oklahoma. If you haven't turned on your air conditioner yet, you will soon. Even though nights are still cool in our area, we're due for some warm days with higher humidity, which will make conditions sticky indoors. So, you may as well get ready for what's just around the corner: summer weather. 

What warm weather HVAC tips are helpful for Broken Arrow homeowners? Let's take a look at what most HVAC consultants recommend.

1. Schedule a spring preventive-maintenance appointment. Yes, of course, we always say this. But the fact is, preventative maintenance is the best thing you can do in spring and fall to keep your HVAC equipment running correctly and efficiently. Have your HVAC tech go over such key parts as the blower, the condenser and coils, the evaporator coils, the condensate drain, the thermostat, the refrigerant lines and levels, the electrical connections, and the airflow. Be sure to discuss what your HVAC technician finds and note recommendations for current or upcoming repairs and replacements of parts.
   

2. Change the air filter. This is just about as important as spring maintenance. In fact, it's considered part of maintenance, especially when it comes to warm weather HVAC. Depending on what kind of filter you choose, you may need to change it as often as every month or every three months. If conditions in your house are dusty or smoky, or you have shedding pets, you probably should check the filter now and then to see if it needs changing more often. Keeping a clean filter in your equipment will allow air to flow through the system so that the AC can cool more effectively and efficiently.
   

3. If your home isn't air sealed, then see that it is. Sealing the minute cracks in walls where conditioned air can get out and hot air can get in makes your home inefficient when it comes to warm weather HVAC. Sealing these cracks — around doors and windows; by baseboards; under electric plates; and around any pipes, wires, or cables in exterior walls — can really make a difference on your electric bill. Have your HVAC tech check your ducts for disconnected or broken sections.

How to Know If Your Home's HVAC System Is Up to Code

An HVAC system that doesn't measure up to existing code requirements can pose a serious risk to your home and to your family's safety, as well as develop significant problems later. But how can you determine whether your system is up to code? Read on to learn more.

Correct Sizing

For your heating and cooling equipment to be code-compliant, it must be sized based on your home's energy load. That requires a qualified HVAC technician to come to your house before HVAC installation and look at your home's size and conditions, such as:

• The placement of doors and windows

• The number of windows

• How much insulation is in your ceiling and walls

Your technician will consider these factors and calculate the size of the HVAC system you need for optimal efficiency.

Energy Efficiency

According to building code provisions, the efficiency ratings of your new or replacement HVAC equipment must be equal to or higher than the minimum that federal law requires in the geographic location where you're installing the equipment. In Oklahoma, the minimum SEER (Seasonal Energy Efficiency Ratio) required for new air conditioning systems is 15 for units rated less than 45,000 BTU and 14.5 for units rated 45,000 BTU and above.

Equipment Location

HVAC equipment location is also critical to compliance with rules and regulations. Your home's HVAC equipment should be located where it allows for repairs, maintenance, and replacement. According to the Oklahoma Building Code, your condensate drain shouldn't discharge into an alley, street, or any other place where it can cause a nuisance. If the condensate drain terminates at a French drain or pit, the pit or drain should be at least 30 inches away from your foundation's outer edge.

HVAC Tuneups to Stay Up to Code

Getting regular tuneups is crucial to ensuring your system complies with the local HVAC codes and standards. For example, during a furnace tuneup, an HVAC professional will ensure your system is up to code by checking the gas supply and ensuring your unit burns safely.

Simply put, having a local, licensed HVAC professional install your HVAC equipment and perform regular maintenance checkups will help ensure that your heating and air-conditioning system is always up to code.

Do You Have an Energy Efficient HVAC Unit in Your Home?

Energy efficient HVAC units do more than simply keep you comfortable at a lower cost. Today, the most efficient air conditioners and furnaces also tend to incorporate the latest technology and provide the most effective cooling and heating performance.

But how do you know whether a unit installed in your home — or a new one you’re considering purchasing — is an energy efficient HVAC model or a standard model? Established industry metrics can help you determine the efficiency of a furnace or AC.

Energy Efficient HVAC

Gas-furnace efficiency is indicated by the unit’s AFUE rating. Short for Annual Fuel Utilization Efficiency, it’s a percentage that expresses the amount of useable heat energy generated by a furnace versus the amount of heat lost in the heating process.

• A standard-efficiency furnace generally has an AFUE of 80%. Standard furnaces typically intake combustion air from the house and incorporate a single heat exchanger.

• High-efficiency furnaces have AFUE ratings above 90%. These units bring air in through a dedicated intake pipe. In addition, they include a secondary heat exchanger that extracts additional heat from the exhaust flow.  

• While the upfront cost of purchasing and installing a high-efficiency model is higher than a standard-efficiency unit, over a period of time, the reduced gas consumption can be expected to compensate for the initial higher cost.

AC Efficiency

Air conditioner efficiency is indicated by the SEER (Seasonal Energy Efficiency Ratio) rating. This numerical rating is computed by dividing the total BTUs of cooling in a typical season by the watts of electricity consumed to operate the air conditioner.

• The higher the SEER rating, the more energy efficient the AC will be.

• The current required minimum air-conditioning standard-efficiency rating is SEER 13. A high-efficiency SEER rating today may rise as high as the mid-20s.

• High-efficiency air conditioners typically incorporate improvements like advanced coil materials, a multistage compressor, and a variable-speed blower to produce improved cooling at lower costs.

How to Tell If You Are Using a Certified HVAC Tech

The HVAC technician you allow to work on your heating system or air conditioner should be a competent professional. Certifications are among the best indicators of an HVAC specialist's knowledge and skill. These certifications are granted after a technician meets the certifying body's precise requirements, which may include participating in technical or professional programs, demonstrating technical knowledge, and passing rigorous exams. Here's how to know if you're working with a fully certified HVAC tech.

Verify the HVAC Certificate

You should start by asking to see the local heating and cooling specialist's HVAC certificate. Contact your state's department that's in charge of licensing and registration after noting the HVAC professional's certification number. The department representative will confirm whether the certification number exists and belongs to that HVAC contractor. If the number can't be found, you can ask the department representative to search for the professional's name to verify that they are a certified HVAC tech. You can also ask the representative for more information on the HVAC professional's training and education.

Check the EPA Certification Card

The Environmental Protection Agency requires HVAC technicians who handle refrigerants to hold the EPA 608 Certification, making them a certified HVAC tech. Passing the EPA's exams shows that an HVAC specialist can safely handle these dangerous chemicals. To verify a technician's certification, ask the technician for his or her certification card. The card should have the technician's name, certification number, and the date the technician took the certification test or became certified.

Keep in mind that hiring an HVAC technician who hasn't been certified may void your manufacturer's warranty. Therefore, make sure you do your homework and only work with a certified HVAC tech.

How an HVAC Professional Should Behave While in Your Home

When you need HVAC services such as routine maintenance or repairs, it’s important to receive superior customer service from the HVAC professional who comes to your Broken Arrow home. What kind of behavior and professionalism should you expect from HVAC technicians? Any HVAC professional who comes to your home should have the following qualities.

Expert Knowledge

Your HVAC system is one of the most expensive components of your home. Whether you need routine HVAC maintenance done or a whole new HVAC system installed, the HVAC technicians who handle these tasks should be experts. Having technical expertise helps ensure that any HVAC services you need are done properly. Keep in mind that your HVAC technicians should have knowledge of different types of heating and cooling systems and their parts, including heat pumps and furnaces, central air conditioners, thermostats, and more.

Excellent Communication

Your HVAC technicians should answer any questions you have about the services they’re providing. If there are any problems with getting the work done, such as needing to wait for parts that are back-ordered, they should let you know. Having good communication skills is just as important for HVAC technicians as is having technical expertise.

Courtesy

HVAC technicians should be polite and courteous when interacting with customers. When an HVAC professional comes to your home for installation, repairs, or maintenance, they should treat you with respect. They should be willing to patiently explain the work they’ll be doing and encourage you to ask them if you’re not sure about something.

Focus on Safety

HVAC technicians perform work that comes with certain hazards, so a focus on safety is crucial. They should know how to turn off power to your HVAC system before starting work as needed, for example. HVAC technicians should also take steps to perform all work while ensuring that you and your family are safe.

What to Have Inspected During an HVAC Installation

Do Not Display

The technicians who arrive to perform an HVAC installation in your home are experienced professionals with industry-recognized credentials. Certain preliminaries may already be completed before installation day. “Sizing” is a technical procedure that ensures a new unit has the precise BTU specifications to efficiently, effectively cool or heat your home. Also prior to HVAC installation, the condition of existing ductwork is typically inspected for leakage or other issues.

Ask your contractor about the critical aspects of installing a new furnace or air conditioner. Here are some routine steps that occur during an HVAC installation that you’ll want to be aware of:

• Refrigerant check. A new central AC needs to be charged with the precise amount of refrigerant per the manufacturer’s specification. Technicians use detectors to check for refrigerant leakage during the initial test operation.

• Condensate drainage. A central air conditioner generates many gallons of liquid condensate in daily operation. Installation of a new AC condensate system includes testing the drip pan and pipe that drains condensate into the home's plumbing. 

• Thermostat location and wiring. The thermostat for the new unit should be situated away from  direct sunlight or near exterior doors that admit hot or cold drafts. If upgrading from a standard manual model to a new programmable thermostat, additional wiring will be needed.

• Electrical connections. A new AC or furnace incorporates wiring, contacts, capacitors, and relays that technicians will test for continuity and safe operation. Also, the central air-conditioner compressor will require a dedicated 220-volt circuit.  

• Outdoor matters. The outdoor component of a central AC must be situated to minimize accumulating leaves, falling ice, or other debris. Unit should be slightly elevated above ground level to avoid inundation during heavy rain.

• Safe heating. A new gas furnace should be tested for hazardous carbon monoxide levels during operation. Safety components that shut off the unit in case of overheating or other malfunction should also be verified. Also, the vent pipe for a standard gas furnace should extend to the roof without leaks or obstruction.
