"McLay Services did an excellent job on the preventative maintenance for my A/C system. Dylan was professional, courteous, and thorough throughout the visit. He replaced two air filters, cleaned the coils, and checked all electrical components to make sure everything was running safely and efficiently. My unit is now healthy and fully operational. I really appreciate the quality of work and attention to detail — I'd definitely recommend McLay Services to my friends and family!"

"HD Mechanical did an excellent job. After trying to fix my water heater, the tech offered me two solutions, the first to repair the old unit and the second to replace it. I chose to replace the unit because it was 20 years old. He was able to return in two days and spend many hours at my home. The tech was courteous, professional, explained everything and made sure everything was working properly before he left."

"Mike came out and helped us with our plumbing issue, great service!"

"We would HIGHLY recommend Joseph from Canyon City Air if you are in need of a new HVAC system or in need of service! He and his crew performed excellent work. They were professional, friendly, detailed, knowledgeable, honest, and cleaned up everything thoroughly afterwards. He even contacted us a couple of days later to check in with us!"

"We were so happy we chose Magnolia Cooling and heating to repair our heater/air conditioner. They were professional from beginning to end. Our serviceman arrived on time and completed the repair to our satisfaction."

"This review is long overdue. Better late than never. This AC service was beyond the best we could hope for. Fantastic job."

"Sev was a total gentleman & didn’t mind letting me know the problems he was having while diagnosing the overall situation, which is very important to me. He also put up with my tiny rugrat as he lay on the floor to get to wires & she fighting to get to his ankles for a good cleaning! Thank goodness the owner was there to intervene! Really, though, Sev went out of his way to make sure I had AC today & not a moment later! He even threw in a much needed extra in order to make sure my ac was cooling at top speed! I’m grateful & my tears of relief are real. I don’t do well in the heat & my landlord is not really able to help me with this issue now. I can finally rest well tonight! Thank you, Sev & southland heating & AC! I truly appreciate it! And, also, much gratitude for Angie’s List for making it so much easier to find trustworthy repair companies!"

"RKM did a great job! They came out very quickly, despite a heat wave and I'm sure a high volume of calls, and assessed and fixed my air conditioner at a reasonable price. I felt very confident with the services provided and would definitely hire them again."

"It went extremely well!! The technician was courteous, knowledgeable, professional, and did a fantastic job. In the 12 years that we have owned our home, I can honestly say that Water Heaters Only is the BEST company we have dealt with in having repairs done. It’s too bad they only work on water heaters."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."
