Once, an aged wire disintegrated, it was not caught during a maintenance visit - I had to pay them to fix. Last year, within about 1 month of their maintenance service visit, the capacitor went out - - -( it was not caught during the service.) I had to pay them 195 dollars to come out and replace it. ( I checked the capacitors are $14.00 online.) I had a maintenance visit on 10/29/2025 - TODAY I woke up to no heat - so I reached out to another company because at this point I DO NOT TRUST Dalton Heating and Air - Come to find out that the Schrader valve has leaked out 8 pounds of refrigerant . . . $$$$$$$ to replace it! When I reached out to James W, (I have had several conversations with him, and he has ALWAYS been short and rude), he advised that it could have been caused by a technician putting gauges on and off the unit. Then he repeatedly asked me WHO I had working on my unit. . . . . For the service I have received from Dalton Heating and Air vs the constant paying more for this and this and this. (Because it has not been caught during maintenance THAT I PAY FOR) In my opinion They ARE NOT worth cost.

From my initial in-person conversation with Jack to telephone conversations with Angie to the heat…read morepump installation today by Rhett and Chris, I've been impressed with their knowledge, courtesy, ability to clearly communicate, and efficient functional installation. Jack quoted me four brands of heat pump, advised their credit agreement, and impressed me with his knowledge. (I spent 5 years helping my former husband with HVAC, including some technical training, so while much has modernized, the basics remain the same.) Rhett called to advise me they were on their way, and the removal of my old, poorly functioning, heat pump and installation of the new one were done quickly and obviously well since my home is again at a temp of 72 degrees in spite of outside temp of 37 degrees. When Rhett first started the system, the temp rose 6 degrees in about 15 minutes. I'm very grateful, because I struggled with an indoor temp between 60 and 66 during our coldest outdoor temps and power bills between $225 and $600, amounts far higher than ever in my entire life. Thank you, Air Heat.

Found Stan through a comprehensive "word of mouth" research. Then checked usual sources and found…read moreremarkably few "lower 5 star comments", so scheduled a "Winter Check-Up" for the system I inherited when I purchased my condo. I was skeptical despite home inspection since previous owners had been less than honest, replacing new stack W/D with an old worn out one ( suit filed) But I digress...the young Tech from Stan's arrived on time. He was thorough and helpful. He gave good comments on why performance was what it is and made helpful suggestions to get the best from the system. He spent lots of time both inspecting and reviewing his findings. I'm now a preferred client; they will be back next Spring and come running if needed in the meantime. Stan's is just as excellent as described. I would recommend them for reliable, honest, economical service.

They also knew we had a smart thermostat installed prior to the "upgraded" replacement system, but then informed us that this new system cannot support smart thermostats AT ALL.

He was pleasant and very knowledgeable and fixed my problem in two visits. I love working with people who know their craft. He explained to me the exact problem and solved the whole issue immediately. Bill had all of the diagnostic equipment to ensure the unit was operating effectively and efficiently. I was very impressed. I had another Signal Mountain provider first assist me with my A/C unit and they sent some very inexperienced people to add too much Freon to the unit so that it could have caused a complete breakdown. Additionally, I called for them to come out on a different issue they fixed. However, they had to come back a second time for an issue I believe they caused while fixing the first. I spent too much money dealing with inexperienced people from this other company. I would go directly to Superior Air Systems
