What Your Neighbors are Saying about Us

"He was very professional, told me what was wrong and fixed the problem".

Angela. P  in Blacksburg, SC

"Truly Great Service"

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"

Kristen Cozzarin in Charlotte, NC

"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

On time, fixed the problem very quickly, did not try and sell any other products. Would call him back if I have any other problems.

Frank Gray in Fort Mill, SC

Hi, I just wanted to thank you for fast and Great service!!! I am very pleased!!! I would highly recommend to anyone!!!

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

Kathleen Leahy, Charlotte, NC

" Donnie, the owner, is extremely personable and easy going. I'd definitely recommend him! It's a Christian Based Business so that's a plus also"

Lisa Cunningham-Charlotte, NC

SUPER FAST RESPONSE!!! PROFESSIONAL & FRIENDLY. I put in a service request at 7:30 Pm and All-Phase Heating and Cooling called me back within 10 minutes to schedule service. They came out first thing in the morning and FIXED A/C UNIT IN A JIFFY! Excellent Service, and Very reasonable Prices!

​Frank Stone-Fort Mill, SC

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!

Ronald. H- Winnsboro, SC

 Donnie Came out on Saturday to work on our Heating unit and could not be any more friendly and Professional in the repair of our heating system. I would  highly recommend your services to everyone. Thanks again Tom Parker.

Tom Parker- Tega Cay, SC

Excellent service and very friendly. Donnie came out and tuned up our units and was very professional and knowledgeable. Fair pricing as well. Would highly recommend.

Jesse A.- Matthews, NC

“They were early for their appointment and were straight up with us. They showed us there was going to be a problem with the AC when it comes time to use it, gave us an estimate and didn't preasure us to schedule the work today. Thank you!”

MICHELE M- Matthews, NC

“They were on time professional and honest. No pressure and to the point. I will use there services again.”

XAVIER-Charlotte, NC

“They were very efficient and thorough”

Lisa P-Charlotte, NC

Prompt and courteous. Came out within 24 hour of my call. Serviced and repaired my system quickly. Explained what was wrong and saved me from 2 service calls by seasonally servicing while he was here. The big guys don't. Owner operated local business who is proud of his work and his reputation. Will call him for all services.

Kristine Kozzen - Cramerton, NC

Thank God, a hard working man that is honest and has the best prices in town. Donnie, God Bless you and your family... My AC unit froze up and had no air period. Donnie comes over and waste no time. Goes upstairs and discovers an instruction manual from the original insulation that was left behind in the blower motor. This manual was burnt and riddled in pieces in the blower motor. My town house could of caught fire. Donnie also replaced missing screws that were never put back. After 4 times the original company came back to fix this unit the first year I lived here. I will not mention their name but Donnie knows. This town house was built brand new in Oct. 2009 and I moved right in. Come that summer that company tries to fix it 4 x. If you want the job done right the first time and pay a fair price??? Call All-Phase Heating and Cooling, ask for Donnie. No one better!!!

Thanks again Donnie
JR- Fort Mill, SC.

Serviceman/owner arrived early for appointment, was friendly, informative and helpful. Will hire again!!

Gayle Amiott- Fort Mill, SC

super nice guy! Told me I would need a new part but was not pushy. I would call him again :)

Mike-Charlotte, NC

Even on a 98 degree day he was prompt, knowledgeable, friendly and his repair rates were more reasonable than any of the other three companies we had used in the last 6 years. In our opinion All Phase Heating & Cooling will always be our HVAC service company. Thanks Donnie for doing such a great job on our home in Lynnwood Farms.

T.J & Nicole- Fort Mill, SC

Donnie has been prompt and professional over the last 2 years while we were trying to prolong the life of our air conditioner! He is knowledgeable and has competitive pricing. My husband and I would definitely recommend him. Thank you Donnie!!!

L. Patterson-Charlotte, NC

We first heard about All-Phase Heating through a Groupon we purchased for an AC tune up. I called the company to make an appointment and spoke with Donnie, the owner. He was available to come out that same afternoon! Along with providing the AC tune up he also addressed another issue we had with the HVAC unit. I cannot express enough how impressed I am with his knowledge, service and honesty. Donnie will now be our "go to" guy for all our HVAC needs and I plan to recommend him to all our friends.

Shelly Bunn- Matthews, NC

Very responsive and easy to work with. Highly recommend calling Donnie.

Maggie Kehoe- Charlotte, NC

Called for repair. He came out in the rain and did an excellent job. Once completed, he charged me a very reasonable price and well below everyone else. He will get my business in the future.

Ginger Crump- Clover, SC

Called for a 2nd opinion. He came right out and thoroughly diagnose and repaired a simple fix that Comfort Systems had quoted me over $2000 to fix.  He then stayed almost an hour to ensure everything was in working order.  Awesome service and very nice man.  I would recommend Donnie to anyone.
