10 Best Heating & Air Services To Help Lengthen the Life of your Heat Pump

Every time you find out that your AC or heat pump unit is not working there is always something you can do to try and fix the problem. Just simply use these following steps:

1. Check All Areas Of AC Unit or Heat Pump 

HVAC maintenance checklist
  • You need to check your air conditioners’ electrical panel and also the outside part that is close to the condensing unit. If either of it is off, you will be required to turn it on.
  • If your unit continues tripping the circuit, you should know that there is a short somewhere and you will require the services of an HVAC technician to help diagnose and repair the entire problem.
  • If the circuits are not at fault, you should then try flushing the drain by yourself. Once you do this check if your unit is working again.
  • If the circuit is on and the drain line is clear and still, your unit is not working, you will be required to check the condensation pump because it may be faulty. If you find the condensation pump is the problem, you will be required to replace it.
  • You also need to check the control boards in the furnace/air handler if they are flashing the LED codes which will be detecting the problem with the use of a code key on or close to the board.
  • If the control board code shows it clearly needs to be reset, you will be required to turn off the air handler/furnace circuit for about 45 seconds and then switch it on once again.

2. If the Indoor Fan is Not Working & Condensing Unit Fan Running

If the outside unit begins running and still your air handler or furnace sails to blow air, then you need to inspect the capacitor, and on this note, you may notice it is leaking some oily fluid or shows some burn marks which means its bulging. 

This is an indication of a faulty capacitor which requires immediate replacement. If the problem persists, you will then be required to test the air handler/ furnace control board and see if a reset is required.

3. If the AC/Heat Pump is not Cooling as Expected

When you realize that your blower and AC are still running but your house is still not cooling:

  • Ensure that your thermostat has not been adjusted to a higher temperature or switched off.
  • Ensure that the furnace filler is cleaned or replaced as required because a dirty filter will always reduce the cooling power of the system.
  • Make sure your coil is clean and this can be done by removing the AC cabinet and gently brushing the coil with a nylon or a natural bristle brush and a hose of the debris as well.

4. If the Air Handler or Furnace is Leaking Water

If this is happening, the obvious reason is if the condensate drain is being blocked and also require flushing. To fix this you will need to check if there is a blockage of the drain pan hole which leads to the drain line. 

Also ensure that you clear the algae, debris, and sludge which may be blocking the flow of water and flush the drain.

5. AC Indoor Coil Freezes Up

If you notice that there is some water on the floor near the furnace area and also if there noticeable condensation on the cabinet housing the furnace, this might be an indication that your indoor coil is completely frozen and will not work at all. 

This normally happens in an area whose weather is very hot and humid and you are running your unit when the temperatures are below 60F. what you need to do is:

  • Ensure you remove the cover or cabinet door of the furnace to see figure out whether or not the indoor coil has been embedded by ice all over. If it is what you need to do is turn off the AC and then set the mode of “fan-only” to the blower which will enable the warm air to go through the coil up to the point when melting starts and all the ice goes away.
  • The moment the ice starts melting, you will be required to asses the indoor coil and figure out if it is clean.
  • You will then clean or replace the furnace filter and this is because restricted airflow causes the coil to get very cold.

6. The Outdoor Coil of Heat Pump Freezes Up

You will be required to check the heat pump system air filter and also make sure that the air vents and all the cool air intakes in your home are not blocked. You will also be needed to re-level your heat pump slab if necessary.

7. If Your Unit is Overcooling

This issue normally arises if your thermostat is near to the heat emitting electronics or lamps are actually emitting heat and your thermostat senses that your house is warmer than it actually is. 

If the area around your thermostat is warmer than the other parts of your house, you will need to at least reset it to solve this issue.

8. If Your HVAC System is Making Unusual Noises

There are some noises your unit may start producing and they may ring a bell that there might be a problem somewhere. You may hear a vibration hum, squealing, whistling, high-pitched screaming, and hissing sound. 

These of your unit parts being faulty. For instance, if you hear a rattling sound, that may be an indication that your compressor may be starting to fail. It will be an indication that you need to replace your compressor.

9. If Your Heat Pump is Not Heating

Causes and solutions for the most common heat pump problems

The reason may be that your thermostat is not sending signals to the heat pump. Another reason would be if your heat pump has been defrosted and still it is under the heating mode. 

Another reason may be because your thermostat has been set on an emergency heat mode or the thermostat is currently not sending any signals to heat or cool effectively. You will be required to reset your thermostat to ensure heating continues.

10. If the Heat Pump Unit Fails To Run As Expected

This may be associated with power problems and therefore you will have to check the power source and connections effectively. You will also need to check the thermostat and see if it is in the required mode of operation.


Now that you know the most important HVAC services for your heat pump, you can either perform them yourself or hire a professional so that you can lengthen the life of your HVAC system as well as ensure the comfort of your home.
