Heat pumps are energy efficient, reducing fuel use by as much as 40 percent compared to standard heating, ventilation and air conditioning systems. Although heat pumps are simple to operate, they sometimes have problems with short cycling or frequent starting and stopping. Short cycling affects indoor comfort because air is not evenly distributed, and humidity is not well-controlled. Here are four reasons why your Buford, GA, heat pump is short cycling:

Improper Thermostat Settings

A poorly calibrated thermostat will cause the unit to heat or cool irregularly, cycle more frequently and use more energy. In cool months, set the thermostat to 65 degrees F or higher. Lower settings may cause the backup heat to come on. In the summer, set the thermostat to 70 degrees F or higher. Lower temperatures may cause the coil to develop ice.

Dirty Filter

Dirty air filters allow airborne particulates to bypass the filter and enter the system. Dust or other pollutants can coat coils and affect heat transfer. Clogged filters reduce airflow. The unit may cycle more frequently to keep temperatures even because insufficient air is flowing through the system.

Improper Sizing

Improper sizing affects performance. An oversized unit will reach the set temperature quickly without controlling humidity, which is important for comfort in northern Georgia. More starting and stopping wear out equipment faster, resulting in the need for frequent heat pump service.

Lack of Maintenance

As with all HVAC equipment, regular maintenance is important. As a Trane Comfort Specialist, Pruitt Heating & Air, Inc. provides heat pump maintenance for Trane products, as well as all other brands of equipment. Preventive maintenance extends the life of the unit, reduces the likelihood of repairs and improves energy efficiency.
