Why Does Your Heat Pump Short Cycle in Hillsborough, NC?

As the summer sun blazes in Hillsborough, NC, your home’s cool refuge hinges on the reliable performance of your heat pump. But if you notice it’s frequently turning on and off, it’s a clear sign of short-cycling, which is a nuisance you’d want to nip in the bud. Let’s dive in and understand the reasons behind this pesky problem and the ways to put it right.

Thermostat Troubles

Your system takes its marching orders from the thermostat. When the thermostat is near a draft or a heat source, it can misread the temperature, causing the heat pump to turn on and off more often than it should. Similarly, a malfunctioning thermostat can lose its command over the heat pump.

Size Matters for Heat Pumps

If your heat pump is too large for your home, it cools the space too quickly and shuts down. Soon, as the temperature changes, it’ll need to kick back on, creating a repetitive cycle of short bursts. This constant turning on and off is short-cycling.

Grime and Grit

Dirt and debris can gather on the key components of your system, like the filter or evaporator coils, blocking the airflow. A heat pump without sufficient air can overheat and shut down prematurely.

Refrigerant Levels Running Low

Your heat pump’s refrigerant pulls heat from the air, playing a crucial role in keeping your home cool. When the refrigerant level drops, the system may not function properly and start short-cycling.

Electrical Hitches Leading to Short-Cycling

Electrical issues can trip up your heat pump’s rhythm, causing it to short-cycle. Loose wiring, a faulty capacitor or a compromised circuit board may be at fault.
