Why is My Air Conditioning Short Cycling?
On a hot Tennessee day, your air conditioning (AC) unit is supposed to keep your home comfortable. So why is it only cooling in short bursts? Short cycling occurs when your air conditioning unit turns on and off in quick sequences.
This common HVAC problem could be happening for several reasons.
In some cases, it’s a simple fix. For instance, a clogged air filter may be stifling ventilation. If your AC has a clean filter, you’ll save as much as 15 percent on your monthly utilities, according to the U.S. Department of Energy (DOE). That’s why we recommend replacing it with a fresh filter at least every 90 days.
Short cycling strains your AC and can shorten its lifespan. It’s also harder to regulate humidity, leading to poor indoor air quality (IAQ). For these reasons, it’s important to remedy the issue ASAP.
Whenever you have trouble with your heating and cooling equipment, don’t hesitate to call Air Conditioning Service for help. Our friendly HVAC specialists are ready to assist.
Why Is My Air Conditioner Short Cycling?
You checked the HVAC filter, and there is no sign of clogging. What could be going on? Here are a few additional factors that lead to short cycling:
Oversized Air Conditioning
When it comes to cooling, bigger isn’t always better. If your system is too large, it will cool your home at lightning speed before shutting off. Simply put, the unit is too good at its job and will end up overworking itself into early retirement.
Additionally, owning an oversized AC means you’re probably overpaying on your monthly energy bill. Need professional assistance? Our expert team can inspect your Brentwood home and ensure your HVAC system is sized correctly for your needs.
Your thermostat gauges your home temperature and lets your AC know when to cool. It should be placed in a central location—away from large appliances (refrigerators, washing machines), as well as drafty or sunny areas (doorways, windows). When misplaced, the thermostat may think it’s colder than the actual temperature. This can make your air conditioner short cycle.
Fortunately, one of our HVAC professionals can move it to a better location for you, if need be. That way, you can spend the rest of this Tennessee summer relaxing.
Low on Refrigerant
Refrigerant is the secret ingredient that makes the cooling process possible. Housed in the compressor unit, it transitions from liquid to gas in order to extract heat and humidity from the air.
When a refrigerant leak happens, your AC loses its ability to function efficiently. Low refrigerant can lead to short cycling, among a host of other problems. Other symptoms include strange smells, hissing noises, and patchy cooling. Think there might be a refrigerant leak? Turn off your air conditioner and schedule a repair immediately.
