I always took my home's heating and cooling system for granted. That is until I found myself battling one of the hottest days in years and my air conditioner simply refused to turn on. After contacting my local HVAC contractor, I learned that my cooling coils had frozen over from a lack of maintenance. He did get my AC back up and running that day, but he also helped me to look at my heating and cooling system in a whole new light. I have spent a lot of time over the last few years learning more about how to properly maintain my HVAC system and ultimately lower my energy costs. Today, I would like to share this knowledge with you so that I can help you to avoid some of the costly mistakes I have made in the past.
Short cycling is one of the lesser-known banes of owning and maintaining an air conditioner for most homeowners. The problem stems from the air conditioner's compressor starting up and shutting down more frequently than it's designed to. Instead of running in 10 to 15-minute cycles two to three times an hour, a short-cycling A/C unit experiences more frequent cycles with much shorter run times.
Short cycling can take a toll on your compressor and other A/C components, guaranteeing a shorter life and a bigger repair bill. If your A/C unit is trapped in a short-cycling nightmare, the following tips can help you break the cycle and bring your unit back to good health.
Change or Clean the Air Filter Regularly
Airflow problems are one of the biggest causes of short cycling, and such problems often stem from a clogged-up air filter. HVAC air filters require frequent cleaning or replacement. Otherwise, the resulting airflow blockage will make your A/C system work harder to circulate air through the unit. Some components may end up working so hard that they overheat and shut down.
All it takes to prevent this from happening is to change or clean the filter at least once every three months. Or you could change the air filter on a monthly basis if you or others in your home suffer from allergies and asthma symptoms.
Watch for Ice Buildup
Heavy frost and ice buildup can be just as deadly for your A/C system as a clogged air filter. While a light dusting of frost is to be expected of a hard-working A/C unit, a thick of sheet of ice suggests major issues. Aforementioned airflow problems can cause lingering moisture to freeze over and stick to the coils, resulting in ice buildup. Low refrigerant levels can also lead to similar issues.
The best way to deal with ice buildup is to prevent it from happening in the first place. Have your HVAC technician keep an eye on your A/C system's refrigerant levels. Don't forget to check for nearby obstructions that could play a role in blocking proper airflow.
Make Sure Your A/C Is the Right Size
If you think you can never have too much air conditioning, then think again. An air conditioner with more cooling capacity than your home realistically needs can fall into the short cycling trap. That's because such units cool your home very quickly, only to operate at shorter intervals than a properly-sized A/C unit.
Making sure you have the right size for your A/C equipment is the only way to tackle short-cycling problems caused by an oversized unit. You'll also get the benefit of generous energy savings simply by upgrading to a more efficient A/C system.
