Why Is My Heat Pump Short-Cycling in Indialantic, FL?

If you use a heat pump to heat or cool your home in Indialantic, FL, you may know a complete cycle lasts about 10 to 15 minutes on average. However, a time may come when it runs for a shorter period and shuts down before finishing a cycle. Let’s take a look at some of the reasons a heat pump might be short-cycling.

Clogged Air Filter

The filter in your return vent collects dust and other pollutants from the air before it passes into the air handler. If you don’t change it out regularly, the pollutants will block airflow, force the air handler motor into overdrive and potentially cause it to overheat. The system will then shut down prematurely to prevent further heat-related damage.

With the standard pleated filter, it’s recommended that you replace it every 60 to 90 days. Fiberglass filters with particularly low MERV ratings may need replacing after 30 days.

Blocked Supply Vent

Ultimately, any blockage to air circulation will increase the risk of overheating and, with it, short cycling. Check your supply vents and make sure to move away any rugs or furniture that are blocking them.

Thermostat Error

Maybe your thermostat is sending your heat pump incorrect signals because it’s misreading the indoor temperature. Professional maintenance can help prevent this because it includes thermostat checks.

An Oversized Unit

Heat pumps have a specific blowing capacity, and it’s possible that the capacity is too great for your living space. You’ll know this is the case if the cycles are short and the temperatures are uneven from room to room. Unfortunately, only a complete replacement will solve this problem.

A short cycling heat pump uses more energy than it should and can raise your monthly energy bill, so you’ll want to have it checked right away. If you live in Indialantic, FL and have a short cycling heat pump, leave the repairs to our experts at Anna’s Air & Heat and contact us today.
