I was called to a home to check on a heat pump that was struggling to keep up with the temperature outside. Upon inspection, I found that the ECM control module was constantly blowing air, and the refrigerant levels were low. I confirmed this information with outside sources and discussed the repair cost with the client. I also discussed the concerns about the compressor running low on refrigerant and the potential for damage to the system. I emailed the client over estimates from several repair companies so that they could make an informed decision about the repair.
