Troubleshooting Heat Pump Problems? It May Be Time To Call A Professional

March 20, 2012 | Blog

Well-maintained heat-pump systems are among the most efficient available. They deliver up to three times more heat energy than the electricity that it takes to run them. This is much greater than the most efficient furnace. However, more than half of all heat pumps in service don’t operate near peak efficiency due to preventable issues with heat extraction, airflow and inefficient ductwork. If you are questioning the productivity of your heat-pump system, it may be time to call a heating and cooling pro.

Troubleshooting heat pump problems

For troubleshooting heat pump problems, ductwork efficiency is imperative. Your ductwork should be adequately insulated and sealed with no leakage or obstructions. This saves as much as 25 percent on your utility costs. Loose joints should be sealed. Registers should be kept open and doors to individual rooms should be kept open.  The air going into each room must be able to get back to the return air for the system.  After your ductwork has been inspected and sealed, accurate airflow and refrigerant measurements are possible.

Air handlers must be calibrated and coils must be cleaned of debris and obstructions for correct airflow readings. Check the air pressure at all air-supply registers for even circulation. The chief indicator for improper airflow is uneven temperatures in your home, which is uncharacteristic for heat pumps. If this is the case, call a heating and cooling pro.

Once the ductwork is efficiently sealed and airflow is optimal, the heat pump can be checked for refrigerant leaks at the heat exchangers, coils and valves. The accumulators should be functioning correctly as well, as this prevents liquid refrigerant from entering the compressor. This can damage a heat pump beyond repair. Once the system has been confirmed (or repaired) leakage-free, accurate measurements for refrigerant levels can be taken. The refrigerant should be charged within a few ounces of the manufacturer specifications. Confirm this with the technician. If the refrigerant is not charged correctly, you can forget about reaping any of the benefits of heat-pump efficiency.

Regular maintenance by a heating and cooling pro is critical for heat pump performance and longevity. Call CCAC, Inc. and we’ll be happy to share with you the benefits of our Service Agreement plan.

Great Company

Great company. Contacted my current AC company to check on my warranty before charging me anything. Saved me a bunch of money and headache if dealing with anything. Would definitely recommend them and use them again.
