"I’m so glad I called HD mechanical to have my thermostat fixed. We set a time to meet up and he was there on time and very professional. He was very thorough with his work and explained to me all the work he performed. He even checked and serviced my unit, showing me that my filter needed to be changed. Would definitely recommend to anyone who needs and service/repairs done."

"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 have used Darrow before for our unit and the condo association and were extremely satisfied. We called him again when our heating unit stopped working. We called on a Friday afternoon and we asked if he could come out the next day or Monday and he insisted that we not wait (since we were having a cold spell) and came out the next day and worked around our schedule. He's friendly, knowledgeable and his price is always fair and reasonable (and he didn't charge extra for a weekend). He also diagnosed the problem right away and didn't try to sell us things we didn't need. He also noticed on the roof a problem with our neighbor's unit and he replaced the cover to a water spout so they wouldn't get water leaking in (and did it at no charge). We're always apprehensive any time we have to hire someone for repairs, but Darrow has proved himself to be our go-to person for heating (and air conditioning should we need that). He has a great work ethic and cares about his customers."

"Excellent diagnosis and prompt service and repair from Southland Heating & Air’s technician Albert Mendoza. Albert successfully resuscitated our LG mini-split inverter by identifying the problem with the unit which called for replacing worn-out sensors. Thanks Southland & Albert!"

"We own a home-based business which relies heavily on our computers operating efficiently. We have had a service contract with another computer repair business for several years. Recently when we were having problems with our computers, we tried contacting our service contractor multiple times. He never responded. Feeling frustrated, I contacted James at North Alabama Technical Services and explained our situation. He instantly came to our rescue. He "cleaned-up" our computers and took care of all the problems we were experiencing. He went above and beyond to help us in our dire time of need. We would strongly recommend James and his company for computer service needs. We have now retained him on a service contract and are looking forward to working with him in the future."

"The service went great. One technician came out and completed the job in about 30 minutes to an hour. The vents had not been cleaned in about 20 years and really needed it. They were very direct and did what I needed. I had no problem scheduling the deal."
