For this job I did a heating tune up. Homeowner does not have replacement filter at this time. HIGHLY recommend replacing. Homeowner ordered on Amazon and will change himself. Deltas good. Drain testing clear. Recommend UV system to tackle biogrowth and produce cleaner air. Heat strip amp draw is good. Tightened electrical connections. At the outdoor unit, refrigerant is good. Running amps are good. Cap is good. Compressor rated for 68 amp start-up. Currently starting on 73 amps. Recommend start kit to lower amp draw and replace extend compressor lifespan. Recommend surge protector. Spoke with homeowner about updating membership plan to H&B Homeowner declined work for today System off when I left.
