What Are the Pros and Cons of Ductless Mini-Splits?

You need a new HVAC system. The typical option is an AC or furnace, but that's not right for every home. Maybe you'd be better suited to a ductless mini-split. Here are some of the pros and cons of ductless mini-splits for home comfort.

Pros

The main advantage to mini-splits is their efficiency. They run on electricity, which allows the most efficient models to have SEER ratings up to 30. The most efficient AC, on the other hand, has a SEER rating of around 25.

That efficiency is compounded by the fact that mini-splits don't lose energy through ductwork. Holes and other damage to your ducts can cause energy loss in your home averaging 30%. Ductless systems don't have that problem, and they deliver all the air directly to you with no loss.

Finally, mini-splits provide zone control. While smaller systems are designed for a single room, larger ones include multiple units, which can be placed in rooms around the house. Each unit has its own thermostat and can be adjusted according to that room's needs — and the occupants' preferences — without disturbing the rest of the house.

Cons

While it's true mini-splits are efficient, they're also expensive. They cost much more to purchase and install than traditional HVAC units. You can make that money back over time through energy savings, but it's definitely a long-term investment, and not everyone can afford that initial cost.

Another problem is IAQ. Ductless mini-split air filters aren't as efficient as regular furnace and AC filters, and they won't eliminate as many contaminants. If you have allergy or asthma sufferers in your home, it might be a good idea to supplement your mini-split with an air purifier.

Ductless mini-splits aren't suited to every home. In the right situation, however, they can be a real asset in terms of comfort, savings, and other advantages. Talk to your HVAC contractor to see if a mini-split is the right option for your needs.

Typical Lifespan of HVAC Components

Your HVAC isn't just some of your home's most expensive equipment, it's also crucial for your family's comfort, so it makes good sense to know how long you can expect it to last.

HVAC lifespan typically ranges from 10 to 25 years, and it varies depending on the equipment type:

Gas furnaces can last for 15-25 years. Most often, they need replacement due to issues like cracks or corrosion of the most expensive component, the heat exchanger. Split-system air conditioners have lifespans of 7-20 years. The summers here in Oklahoma mean that A/Cs get a lot of use, so they may need replacement sooner due to coil corrosion or compressor failure. Heat pumps and ductless mini-splits can last for up to 25 years. Since these units heat and cool, year-round use may shorten their service life.

Other Factors that Impact HVAC Component Lifespan

Beyond the type of equipment, these additional factors can affect the life expectancy of your home's HVAC components:

Initial quality.

Equipment that's cheaply built is less likely to last over the long term, and it can also have construction or design flaws that shorten its life.

Sizing accuracy and installation.

For a long lifespan, HVAC equipment needs to be sized correctly for your home, and installed with care to the manufacturer's specific requirements.

Preventive maintenance.

HVAC components are like any other kind of mechanical equipment: they perform better, break down less often and last longer when they receive timely preventive maintenance.

Ways to Maximize HVAC Lifespan

Here's some advice to help you prevent life-shortening problems in new HVAC equipment or your current components:Only hire a reputable HVAC contractor when you purchase new equipment. This ensures that a load calculation is done to size the capacity correctly, and the manufacturer's specifications and best practices are followed during installation.Invest in twice-yearly preventive maintenance over your equipment's lifespan so it stays in the best possible working condition.

When You Should Use a Ductless, Mini-Split System

If you’re planning to add livable space to your home, you might find that ductless mini-split systems are the perfect way to heat and cool it. A mini-split refers to an air conditioner or heat pump that works just like a central system minus the ductwork.

Mini-splits work well for:

• Add-on rooms.

• Attic or basement retrofits.

• Garages and workshops.

• Stand-alone buildings.

They provide the same level of comfort as central systems do, often with better efficiency. They also solve problems associated with remodeling projects where the ductwork won’t fit easily or the existing HVAC system can’t be extended.

Besides remarkable comfort, mini-splits offer more advantages, like:

• Easy installation. These systems come complete from the factory, where the refrigerant is installed. A mini-split heat pump or air conditioner has an indoor air handler and an outdoor condenser. A flexible conduit contains the refrigerant line, the wiring and a drain line.When installing a mini-split, the technician has to drill a hole for the conduit, position the air handler and condenser, and connect the two. There is no ductwork to install and seal to deliver the conditioned air.

• High energy efficiency. Mini-split systems exceed the energy efficiency of central systems because there are no thermal or air leaks through ductwork. They often have upgraded features that increase their efficiency even more.

When not to use a mini-split:

As advantageous as mini-splits are, they don’t work in every situation. Homes with lots of hallways and interior doors will block the free circulation of air from a mini-split. They’re also more expensive per ton than central systems. If you’re remodeling and need a new HVAC system, it might make more financial sense to install new equipment for the whole house than invest in a mini-split for a small space.

As you move forward with the addition or retrofit, exploring the benefits of mini-split systems will ensure your long term comfort and satisfaction. To learn more, contact Air Assurance, providing trusted HVAC services for Broken Arrow homeowners.
