Question: Are there some recommended items that should be replaced on a 10+ years old Trane heat pump unit?
Answer: Thanks so much for your interest in our website and the opportunity to do business with you! The most common cause for Air Conditioner or Heat pumps not working is the unit being low on refrigerant charge. If you unit is low on refrigerant charge it will ice up, block air flow and not cool at all. A system that is low on charge can cause the compressor to over-heat and go off on thermal over-load. If your outdoor fan is running and the compressor is not running then your compressor might have over-heated and gone off on thermal over-load because the system in low on charge.
The two parts that go out most often on an AC or heat pump are the capacitor, contactor followed by fan motors. We have a list of all the capacitors we sell on the following page: Please click here if you are interested in seeing the capacitors we sell. I would not suggest replacing anything unless the capacitor is weak or if the contactor contacts look worn or pitted. I would suggest having a spare capacitor and contactor on hand in case these go out on a hot summer night or weekend. The capacitor on our air conditioning unit went out on a hot night last year. I was glad I had a new capacitor on hand because I was able to get us back up and going with cooling in 15 to 20 minutes. If the contacts on your unit look worn or pitted then I would suggest that your replace your contactor. Please click here if you are interested in the contactors that we sell. Please send us your unit’s model number if you would like for us to make a capacitor or contactor recommendation. We would like to help you out. Our email address is: email@example.com. We have two YouTube Videos below which explains how to test and replace a capacitor and contactor. Please click here if you are interested in seeing the condenser fan motors we sell.
If you have a gas furnace you might consider having a spare ignitor and flame sensor on hand because these two parts go out most often on furnaces. Please send me your Trane heat pump unit’s model number and your furnace’s model number and I will be glad to look it up and give you the part numbers for the capacitor, contactor and fan motor for your AC and the furnace ignitor, flame sensor and control board. Please click here if you would like to see the furnace hot surface ignitors we sell. Please click here if you would like to see the furnace flame sensors we sell. The condenser fan motors and furnace control boards are pretty expensive so you would not need to purchase these unless you want. Please contact us anytime if you would like to ask a question or have us look up parts. Our email address is: firstname.lastname@example.org. We would love to help you out and have your business! I hope that you have a great day!
