Why Is My A/C Short-Cycling?

What is A/C Short-Cycling?

A/C short-cycling can leave you puzzled and concerned about its impact on your home comfort and expenses. In essence, it involves your heat pump or air conditioning system rapidly turning on and off without completing a full cycle. Despite its seemingly minor nature, this issue can lead to significant consequences, influencing your home’s comfort, your HVAC system’s lifespan, and your monthly utility costs. In this blog post, we’ll explore the ins and outs of A/C short-cycling, shedding light on what it entails and offering valuable insights into preventing and resolving this common concern.

What Problems Does Short-Cycling Cause?

Air conditioners require the most power when starting up. Therefore, constant startups can cause a power drain that dramatically increases your utility bills. Additionally, your compressor can wear out more quickly, leading to a burnt-out unit and reduced useful life.

Dirty Air Filter

Failing to change your air filter may lead to limited airflow. If air cannot flow properly through your A/C unit, heat can build up, causing the unit to cycle off and on. Set a reminder to change out your dirty air filter on a monthly cadence and avoid costly repairs.

Evaporator Coils Are Frozen

Air conditioner coils sometimes freeze for a variety of reasons, including mechanical problems or a dirty filter. Shut down the system, replace the filter, and turn it back on. If this doesn’t resolve the problem, give our HVAC contractors a call!

Wiring and Electrical Problems

An improperly wired A/C unit can short-circuit every time the unit loses power. It’s important to get a licensed A/C specialist in right away to handle the electrical repairs. This poses a fire hazard that threatens the safety of your home and loved ones.

Size of Your System

Believe it or not, if your air conditioner is too big, your home will suffer from inconsistent cooling and hot spots. As a result, your system will run more frequently to match the temperature of each room to that of the thermostat. In order to prevent constant starting and stopping, we can replace your HVAC unit with one designed for the size of your home.
