Heat pumps are common HVAC appliances that are basically use the mechanism of transfer of heat from source to sink. Here are a few guidelines which would serve you well in fixing minor problems in your Houston heat pump. Before you initiate heat pump troubleshooting, make sure that electricity supply to it is turned off.
- If no heat is transferred, check the main power supply. In case it is fine, check whether the compressor motor is overloaded. If yes, pressing the reset button should start the motor. In case it doesn’t work, seek professional help.
- If sufficient heat is not transferred, check for the obstructed air ducts. Other possible causes can be a lower setting of the thermostat or presence of dirt on air filters. Set the thermostat properly and clean the air filters for smooth operation.
- Another reason for insufficient heat transfer is either low pressure refrigerant, compressor damage or an unclean evaporator. Likewise, high refrigerant pressure is usually caused due to excess of refrigerant and an unclean condenser. Check these systems regularly to make sure that heat pumps continue to work without trouble.
- Heat pump freezing is another common problem caused either due to insufficient blower speed or clogging of evaporators or filters. To fix such problems, defrost your heat pump if possible. If such option is not available, seek help of Houston air conditioning repair contractor.
- If your heat pump makes strange sounds during daily operation, check air ducts and mechanical parts of the heat pump like belts, wheels and the like. Fix the causes as necessary and check if such sounds are done away with.
Some additional servicing guidelines to prevent heat pump problems include cleaning fan blades, air ducts and air filters regularly.
