What Is a Manual J Load Calculation?

Manual J Calculation.jpg

Some HVAC terms are easy to understand while others may leave you scratching your head. For many Broken Arrow area homeowners, Manual J load calculation is definitely in the latter category. Not only is it the first step towards choosing the right HVAC system for your home, but it’s also an essential step.

Developed by the Air Conditioning Contractors of America, Manual J load calculation offers homeowners and contractors a way to properly size up a home’s HVAC needs and design an HVAC system that offers the best performance and efficiency match.

How Manual J Benefits Your Home

Different homes have different heating and cooling requirements and it’s easy to choose an HVAC unit that’s ill-equipped to handle your home. Depending on the age-old “rule of thumb” often results in an HVAC system that’s either underpowered or overpowered for the given environment. The former can make your home unbearable during the summer while the latter wastes energy while increasing overall discomfort.

Manual J lets contractors choose the right HVAC system by calculating a home’s precise heating and cooling needs. A typical Manual J calculation takes many of the following factors into account:

  • Square footage

  • Building materials

  • Location and directional orientation

  • Heat gain and loss throughout the entire home

  • Current HVAC system size and type

  • Insulation levels

  • Window types

  • Duct leakage

Using specially designed software, contractors can recommend an HVAC system that provides optimal comfort without using too much energy or wearing out early. Manual J load calculations are commonly done in conjunction with other ACCA design protocols, including Manual S equipment selection and Manual D ductwork design.

No HVAC system replacement should start without a Manual J load calculation. Contact Air Assurance today and let us take care of your heating and cooling needs, using the latest in modern HVAC technology.

5 New Year's Resolutions for Your Home's HVAC System

5 New Year's Resolutions for Your Home's HVAC System

It's traditional to make resolutions at the start of a new year, so now is the perfect time to plan some strategic changes that can help you save money and enjoy a healthier, more comfortable home. Here are five HVAC resolutions that can help lower your energy bills, increase your comfort level and improve the quality of the air your family breathes all year long.

  1. Schedule semi-annual HVAC system maintenance. Keeping your HVAC system well maintained with spring air conditioner and fall furnace tuneups not only improves energy efficiency, but also helps prevent costly breakdowns and prolongs the equipment's service life.

  2. Inspect and change the air filter monthly. A dirty filter restricts adequate airflow through the HVAC system, which makes the equipment work harder and erodes efficiency. A clogged filter also lets debris build up inside the system, which will eventually cause breakdowns and premature component failures.

  3. Use the thermostat wisely. Make sure you take full advantage of the potential energy savings offered by your programmable thermostat in 2016 by scheduling daily temperature setbacks. Programming in automatic eight-hour setbacks while you're sleeping or away from home can reduce your energy consumption by 1 percent for every single-degree temperature change.

  4. Seal and insulate the ductwork. Leaky, uninsulated ducts can rob you of up to a third of your HVAC system's output and significantly increase your energy bills. Having an HVAC professional seal the air ducts not only saves you money, it prevents unhealthy contaminants from being drawn in from unfinished areas like the attic, crawl space and garage.

  5. Boost air quality by adding a filtration unit. Replacing the HVAC air filter on a regular basis can protect your equipment, but this type of filter isn't designed to remove the microscopic pollutants that can adversely affect your family's health. To help everyone in the household breathe easier in the new year, talk to an experienced professional about installing an air purifier or air cleaner on the HVAC system.
