Today I performed a super tune-up on a 4-year-old gas furnace unit checked everything indoor and outdoor running and heat mode and in cool mode changed the filter flushed the drain line with white vinegar safeties check out no reading of carbon monoxide Flames look clean no signs of biological growth at the outdoor unit the capacitor is in range fan motor is just fine however the compressor is over amping upon startup likely culprit of this is the excessive dirty filter as well as outdoor coils thoroughly washed outdoor coils today and changed filter recommended compressor saver kit but the homeowner would like to hold off as we are in the heating season they signed up for the home and budget protection plans so that we can come back out in 6 months to provide them another opportunity to install the compressor saver kit left the unit running in cool mode as I had it nice and toasty while testing the furnace thank you for choosing Comfort Experts
