Gil Jones in Charlotte, NC


"Guy that came out very polite. Explained what was happening. Had to order part. Tried getting it running. Kept freezing up. I called and left message. He came back next day with parts and its running greasy. Excellent job. Would recommend them highly."


Sandra Burton in Lancaster, SC


" After contacting several larger companies about concern with our heating and cooling systems, we were told that our only option was to replace the whole thing. Since this is the most expensive option, I began calling around for quotes and found All-Phase Heating and Cooling, our system is quite old and we have called repair companies several times over the past 7 years. Every time I have been dissatisfied with the quality of service and upselling that  takes place. Donny with All-Phase Heating and Cooling re-installed my faith in heating and cooling companies. He promptly returned my email and even on a saturday, came to my home, free of charge, and found nothing wrong except some loose wires. He tightened them and educated me about the importance of maintaining a system as old as ours, and how this would get the maximum amount of years out of it. If we hire him to maintain it, he even offered discounts on future parts and repairs. I was so happy with the fact that Donny did not try to over sell me and he has excellent customer service. I was treated like a person rather than just one of the hundreds of customer service calls that came in that day. All-Phase Heating and Cooling will ALWAYS have my business and I will insist that all of my friends, neighbors, and family rely on this company for their heating and cooling needs as well"

"I'm usually hard to please  with repair people, but Donnie was very thorough. He even took pictures to show me exactly what was wrong with my heat pump. I will definitely recommend his work to my neighbors and family any time this type of work is needed."


Harold H. In Blacksburg, SC



"Donnie came out and serviced our air conditioner and provided the best services. We contacted him on the weekend and he mad no excuses he came out with no hesitations and he was on time, got the job done and was reasonable in pricing. Thank you Donnie for making our lives a lot easier and less hot! God bless you!"


Candance T in Wingate, NC



"Thank you for a job well done. The worker did not try to up sell me anything or talk to me in a way that I could not understand. He came out and gave me a quote on the heater. He did a great job."


John Mcgoogan in Fort Mill, SC

Joe Aderholt in Lancaster, SC


ABSOLUTELY AWESOME! He knew exactly what was wrong, had the part and repaired in less than an hour. I did not feel overcharged AT All! He knew what he was doing, did not try to "SELL" me anything, looked over entire system. Best part was he was ON TIME, and I did not have to wait to be thrown into a que of customers with no approximate time. He gave me a time frame for arrival and was actually early. GREAT SERVICE! I will be using him for maintenance check ups and all heat and air needs

Thank You, Thank You. Thank you to Donnie at All-Phase Heating and Cooling! He came out quickly and got our A/C up and running again after getting the run around from other heating and cooling companies. He was professional, extremely knowledgeable, provided the best bang for your buck and didn't leave until he was  confident that everything was working 100%! If you are in need of heating and cooling services, give him a call! You will be glad you did! Satisfied Customer!


Michelle C- Fort Mill, SC


After another company failed to come out to repair our ac in more than 100 degree temps, we gave All-Phase a call late afternoon. Our house was nearly 90 degrees upstairs at that point. All-Phase rushed over within the hour and made a temporary fix for the night and will repair completely first thing in the morning when parts are purchased. Service technician/owner was polite and happy to help.


Amy T-Fort Mill, SC


After waiting over a week for another service company that never showed up I contacted Home Advisor. All-Phase was listed as very highly rated. Donnie contacted me within minutes, came out the next morning and fixed the problem quickly. He even checked my other A/C and tightened some fittings at no extra charge. We will call him from now on. He also explained everything as he worked. Really professional and a good person. Plus he liked my jokes!
