Like other home-cooling equipment, heat pumps have a big job to do in Southwest Florida summers. When you have an HVAC technician tune up your heat pump before the intense heat and humidity kick in, you can boost its energy efficiency and ward off potential breakdowns at the height of the season.
Preventive maintenance for heat pumps by a professional technician typically includes:
- Cleaning the air handler and evaporator coil and replacing the air filter if it’s dirty. When dirt builds in the air handler and collects on the evaporator coil, it can cause your coil to freeze over because not enough air flows over it. A frozen coil can ultimately cause outdoor condenser failure (not to mention boost your electric bill).
- Checking your interior ducts to make sure that the airflow is adequate for each room. Ducts can leak or separate at the joints, adding to your cooling costs.
- Inspecting the electrical components and replacing them when needed, as well as tightening all the connections.
- Examining the belt inside the air handler and lubricating the motor.
- Making sure the heating cycle won’t turn on once you set the system to the cooling function.
- Calibrating the thermostat for accurate operation.
- Checking the refrigerant level and bringing it back to the manufacturer’s specifications. If your level is low, the technician also runs down the cause of the leaks. Your heat pump won’t run if the level is too high or too low. Leaking refrigerant is also a health and environmental hazard.
- Clean and straighten the outdoor coils for the condenser and remove any dirt or plant debris that interferes with optimal operation.
The goal of HVAC experts is to bring your system back to its original factory settings as closely as possible. As these appliances run, dirt, corrosion and leaks impede their efficiency, increasing the likelihood of breakdowns and excessive energy consumption.
