Below are few steps that can be useful to improve the performance and efficiency of heat pump.Change air filter : Fix duct leak.Service your pump on regular interval.Use programmable thermostat.
Interestingly enough. I recently experienced a failed condenser fan motor (partial bearing seizure) in the condenser unit. These motors typically use sleeve bearing (no means for lubrication) and are made in Mexico. These motors cannot be repaired successfully due to their pressed and crimped construction. I ordered and installed a new condenser fan motor (about $100.00 on Ebay) and all is now well....except for one thing... when the condenser shuts off, there is a noticeable "bang" noise. I do not know the source of this bang...I have checked mounting screws and other stuff I disturbed when I removed the fan assembly and can find nothing wrong or adrift. I may replace the load contactor in the condenser just to eliminate it as the culprit. I may also change the motor start capacitor for the same reason.Any thoughts from any of you experts or non-experts regarding the bang noise?Also, does anybody wish to purchase my unwanted R22? If so, let me know. The R22 weighs about 36 lbs. which means that the cylinder is likely about 3-4 lbs. shy of a full cylinder.

The technician can do the following:-Verify correct refrigerant charge by measurement-Check for refrigerant leaks-Inspect electric terminals, and, if necessary, clean and tighten connections, and apply nonconductive coating-Lubricate motors, and inspect belts for tightness and wear-Verify correct electric control, making sure that heating is locked out when the thermostat calls for cooling and vice versaVerify correct thermostat operation.
