For this job I did a super tune up. Deltas are good. Filter changed recently. Drain is clear. Furnace components are good. Tightened electrical connections. Recommend UV for allergy relief Outdoors; refrigerant, running amps, start kit, & cap are good. Washed coil. Suggest upgrading to soft start. Recommend surge protector. Spoke about updating to H&B and she agreed. System off when I left.
