Heat Pump Service


Benefits of Preventative Heat Pump Service

Much like a central air conditioner, heat pumps rely on air movement through an indoor and an outdoor coil to generate comfort for your home. Keeping the system cleaned, checked and maintained helps to protect against sometimes costly and inconvenient heat pump repair service. It’s also a great way to help:

  • maximize energy savings
  • reduce wear & tear on components for longer life
  • save time and money in the long run with fewer unexpected breakdowns or repairs

When you schedule an appointment with a certified HVAC technician, you are taking a great first step toward enhanced comfort and potential savings on heat pump repair services for the long run.

Increase Energy Efficiency

Without getting too technical, your heat pump relies on a large coil in the outdoor unit and second coil inside your home to provide heat transfer for both heating and cooling your home.

The outdoor coil is exposed to the elements year-in and year-out, accumulating dirt, debris and other pollutants, especially when it is wet from either weather or the heating and cooling process.

The indoor coil is located in or on your indoor air handler unit (either a furnace or fan coil). It can attract airborne pollutants such as dust, mold spores or pet dander because of condensation associated with air conditioning and heating your home.

Both coils operate most efficiently when they are clean and free from buildup of dirt and debris. Without regular cleaning and maintenance, dirty coils can cause your system to work harder to keep up with heating and cooling demand, decreasing efficiency and increasing stress on fans, motors and other system components.

Keeping the system’s air filter clean and replacing it regularly can also aid efficient performance. Dirty, clogged air filters can restrict airflow, resulting in reduced comfort, higher utility bills and, in more extreme cases, a total shutdown of the system.

Extend the Life of the Unit

Consider regular air conditioner or heat pump maintenance to be part of a complete home improvement plan. Proper maintenance of your heat pump system can not only help to save on heating and cooling costs, as outlined in the previous section, it can help extend the life of the unit in a number of ways:

  • Clean coil surfaces and air filters allow unobstructed airflow, reducing wear and tear on equipment;
  • Proper refrigerant charge allows the system to operate as designed. Systems running low on refrigerant struggle to keep up with heating and cooling demand and can cause serious damage to the compressor; and
  • With regular inspections, minor heat pump repairs can usually be made at lower cost, before bigger issues (and bigger repair bills) pop up

Save Time & Money in the Long Run

Without regular maintenance, your system is more susceptible to malfunctioning at the worst possible time – when the system is working the hardest during extremely cold or hot outdoor temperatures. Replacement parts and repair costs from emergency services can put a big dent in the wallet. By having the unit regularly serviced, you can potentially avoid these unexpected costs to help save money in the long run. You could also enjoy increased energy efficiency and lower monthly utility bills for the life of the system – the longer the system lasts, the more potential to save!

What is Checked During Heat Pump Service

During a routine maintenance service call, your dealer will likely evaluate your home’s heat pump system performance while the thermostat is set in various modes of operation. This will help to determine its condition and whether repairs or adjustments are needed. Then they will shut off electrical power to execute a number of cleaning and inspection tasks. Maintenance services will vary from contractor to contractor, but most HVAC dealers will perform similar tasks as part of a standard “clean and check” appointment, including to:

  1. Check refrigerant charge levels and air flow, check for refrigerant leaks
  2. Make sure all electrical connections are sound and components are working properly
  3. Check for secure physical connections of individual parts
  4. Check the run capacitor for bulging and/or unusual markings or color
  5. Check and clean the outdoor unit & coil
  6. Check & inspect the reversing valve
  7. Test the defrost cycle
  8. Check the auxiliary heating system and test for heating in defrost mode
  9. Check indoor coil for blockage and apply self-rinsing cleaner when possible
  10. Check and clean the condensate drainage system
  11. Clean and adjust blower components in the air handler unit
  12. Check the air filter, and replace or clean, if needed

When the service is complete, many contractors will provide a written summary of the inspections and tests completed along with results and recommendations. In some cases, needed repairs may be completed on the spot.

Heat Pump Repair Service

A malfunctioning heat pump can result from a myriad of issues. Three commonly reported issues include:

  • Heat pump frozen – In winter, a frozen heat pump might be the result of the defrost cycle not working, the outdoor fan not working, low refrigerant charge, the outdoor unit being physically blocked, or water dripping onto the unit and freezing. A frozen heat pump won’t heat, and worse, can lead to severe damage or failure if allowed to operate. During summer, a freeze up can happen on the indoor coil, or copper line leading to the compressor as a result of a low refrigerant issue, a clogged air filter or extremely dirty coils.
  • Running constantly – In winter, check the thermostat to be sure the heat pump isn’t set for cooling. Other reasons may be a frozen outdoor coil, a compressor problem or a dirty and poorly maintained unit. In summer, check to be sure the system is not in heating mode. Other issues may be triple-digit temperatures, refrigerant leakage, or a dirty/clogged coil or air filter.
  • Blowing cold on heat mode – Check to see the thermostat wasn’t changed to AC/cool mode. If not, the problem might be low refrigerant charge, or a reversing valve or compressor issue. It could also be the result of poor maintenance and a dirty/clogged coil.
