The Importance of Biannual Ductless Maintenance


Ductless or mini-split HVAC systems have a lot of benefits. First, they don’t require ductwork, so they’re an ideal solution for older homes that were built without ductwork, or for avoiding the cost and hassle of replacing damaged ductwork. Second, they are extremely energy-efficient, saving you money every time you pay your utility bills and doing the planet a favor. And third, they do two jobs, smoothly transitioning between heating and cooling as the seasons change. That third factor is the most important thing to consider when you’re scheduling maintenance for your ductless system.

When your AC and your heat are provided by two systems, they should each be maintained annually. Your ductless system does both jobs and needs to be treated as such. This means that biannual ductless maintenance in Corinth, TX is necessary for your ductless mini-split to function as well as it should.


As we mentioned, one of the greatest benefits of having this type of comfort system in your home is that it is extremely energy-efficient. However, any kind of HVAC system decreases in efficiency when it is not regularly maintained. Wear and tear, friction, and the strain of pulling air through clogged or dusty components will gradually reduce the efficiency of your system. Your maintenance technician will clean out any dusty buildup, lubricate moving parts to lessen friction, and make sure everything is tightly secured and properly calibrated to give you the most efficient performance possible from your ductless system.

While a furnace or an air conditioner just accumulates that wear and tear during one part of the year, your ductless system does it all year long. To take that extra workload into account, you need to have maintenance done twice a year.

Problem Prevention

The first signs of HVAC trouble that a homeowner will notice are often loud, unexpected noises or a failure to operate. These are indications that a problem has been developing for a while. To catch problems before they get that bad, it’s critical to have a trained professional regularly inspect your ductless system.

For example, if a screw is loosening, or a fan blade is wobbling off-kilter, it can be secured before it comes free and damages another component. If a refrigerant line is damaged, it can be fixed before it leaks enough refrigerant to cause the unit to stop cooling. If a drain or condensate pan is in a position that allows water to pool, that can be adjusted before you end up with water damage or a mildew problem. In fact, having biannual maintenance done dramatically reduces the likelihood that you’ll need to call us for repairs at other times of the year. 


The ideal schedule for your biannual ductless system maintenance is every spring and every fall, between the heavy-use seasons. However, if you’ve missed the ideal window, don’t put it off any longer. It’s better to have it done as soon as you can so that you can reap all the benefits of this efficient, convenient heating and cooling system.
