“I could not be more pleased with this company. They came first thing in the morning after calling them the night before. Casey was very friendly, professional and knowledgeable. He quickly identified the issue with my AC unit and let me know how much it would cost to repair. He gave me some great tips on how to keep up with maintenance on the Furnace and outside unit. I always appreciate a company that doesn’t try to up sell on things not needed. Casey had me up and running within an hour! Highly recommend!“

“If it were possible, I'd give this job 4.5 stars. The electrician was great: friendly, knowledgeable, informative, and efficient. He was willing, if necessary, to stay late on a Friday afternoon to finish the job, but he was done well before EOB. So the only reason I didn't give the job five stars is that our discount as Home Protection subscribers seemed surprisingly small, ~$130 on a $900+ job. That's better than nothing, certainly, but given how much we spend every month and every year on the plan, I thought the discount would be a little more substantial.“

“Seliga does very good work, I had them for maintenance on my furnace, they cleaned and check pretty much everything and made sure their were no leaks, it's running great, I am on the monthly maintenance plan so it didn't cost much. Nate was my technician, he always does good work“

“INCREDIBLE customer service! From scheduling the after hours appointment, to Geoffrey explaining everything to me, their service is the absolute best.

“When our air conditioning went out over the weekend, I searched for a 24 hr service business. We are glad we called Reliable. They were quick to respond. Marty was professional and friendly. He had it fixed quickly, despite the rain. I feel the fees were reasonable considering it was the weekend. Reliable will be our “go-to” for any maintenance, repairs, and eventual replacement going forward.“

“Wayne and his team at Jewell have worked on two of my homes. Their work has always been cost effective and done by people that have a great understanding of various construction activities. There have been minimal call backs when something was not quite right and they always stood behind their work. Their communication is always timely. It always felt like they were that family member that just knows how to do everything that I can’t and willing to lend a hand.“

“Tony did a great job diagnosing the issue the with the system and explaining things. Thanks for coming out, talk soon“

“We needed a new dang a/c in the burning miserable heat of summer. Other companies gave us the run around if they even got back to us at all. Airpro came out immediately, were incredibly nice and friendly to deal with. They had an entire new a/c and coil installed in no time. Back to happy life. Other companies said they couldn’t get to us or get the unit we needed. Airpro was really great to work with. Pretty sure my wife is going to make out with me more often now because she’s so grateful for conditioned air again. I credit Airpro. Melissa, Dan, and the install team were all wonderful people. Highly recommend.Service: Installation“

“Called yesterday to required about services and Glenn was going to squeeze me into his schedule that day but I informed him that I was unable to be at home and he stated he could come by first thing the next morning. When he arrived, he had an expert knowledge and professional manner. I highly recommended his services.“

Upon walking through our 115 year old home they also provided good recommendations on home improvements we could make to increase the efficiency of our system. On installation day they were on time and very respectful of our home, and were always very friendly. Highly recommended“

“Great guys and prompt service! They were able to quickly diagnose my issue with a blower that wanted to only work sometimes, and gave me a breakdown on parts cost. I definitely recommend giving Knowles a call for your heating/ cooling needs.“

“I had nothing but great experience with Bart Inman Air Conditioning &Heat. They installed my entire system fast and with an extreme professionalism. Since the moment Ive called to make an appointment for a bid until the moment it was installed . They even did a follow up a month later. Came and looked at it to make sure that everything operates , and was done properly . Not to mention, they were a lot cheaper than the other companies Ive called. Their technicians are professional and polite. I have nothing , but good things to say about this company.“

“Needed a new system, someone referred me to Scott-Lee, and their confidence was justified. The salesman came out, saw what we had, and provided a range of options, all of which would have resolved our problem. We selected the one most appropriate for our situation, set an installation date and they took it from there. The installers were professional, didn't make much of a mess, and cleaned up after themselves. Realistically, we couldn't have asked for more. When I hear of someone needing HVAC work done, I will be the one recommending Scott-Lee.“

“STH&AC were very responsive. From the initial phone call to diagnosis and maintenance on my AC they were thorough, professional, and friendly. A sout out to my technician, Austin, who did a great job explaining what was needed, what it would cost and recommending what I should do to keep my AC running well. In fact, I plan on using them this fall to do a check-up and any maintenance on my furnace.“
