Today I performed a winter time maintenance on your HVAC equipment. Overall everything looked to be in fair to poor condition. I started off checking the difference in temperature between supply and return air. I observed a return air temp of 70° while supply air was 59°F. This is a low temperature split for the efficiency rating of your unit, which tells me there’s something going wrong. The indoor conditioning (evaporator) coil was relatively clean considering the age, but in poor condition. I checked the operation of the compressor, condenser fan and their respective capacitor. Everything was within manufacturer specifications. Pressures looked low, I couldn’t read subcool and superheat due to there being no access to the compressor aside from the top where the fan is. I finished up treating the drain with chemical to prevent a clog. I have scheduled a service and new unit quote appointment for you on Monday 2/23/25. Thank you for choosing
