Just had Russell out with One Hour Heating and Air. We are getting ready to sell our home and the home inspector noticed a problem with our 10 year old heating unit. Russell was able to diagnose and fix the issue in just minutes! I highly recommend One Hour Heating and Air…and we’ll be using them to service the units at my new home.

Russell fixed our AC issue quickly, checked our other unit, and offered the most affordable price with a yearly maintenance plan that lowered our AC costs. He was friendly, kind, and explained everything clearly. One of our best experiences!

I've never been so excited to spend money in my life, but after dealing with Lance and his manager Don, there was no way I was going with another company. Lance was patient, returned my calls and emails and made 3 house visits in order to meet my expectations. I couldn't ask for anything more.

Superior Indoor Comfort, Inc.

Low-rated; tighten your due diligence

With a 2/5 average from 482 reviews at 3.21 km, Superior Indoor Comfort, Inc. ranks last in our Forsyth County snapshot. A low aggregate score can signal uneven customer satisfaction relative to peers, so proceed methodically. Verify current licensing and insurance, confirm brand-specific training, and request three recent references for similar system types and tonnage. Define scope in writing: Manual J results, any duct modifications, line-set strategy, condensate management, code compliance, and permit responsibilities. For replacements, ask for an AHRI certificate, stated SEER2/HSPF2, and a commissioning plan that documents static pressure, target CFM, and verified superheat/subcool.

If you solicit a bid, require: itemized equipment by model number, labor hours, start/finish dates, permit number, rebate processing, warranty terms (parts and labor) in years, and a milestone-based payment schedule. Compare at least two alternatives (include Gee) on total cost of ownership, not just tonnage or headline price. Request before/after photos and a post-install report, and set response-time expectations for warranty calls in writing. Confirm proper recovery and disposal of refrigerant and equipment per EPA rules. These steps mitigate risk and help align outcomes with your performance and reliability targets.
