The night before we were scheduled to leave town for 5 days, our heating system started making a…read morehorrible racket. Of course this is December, and of course it's supposed to freeze the following week. I immediately started looking for a heating and air company that had good ratings and one of the first to pop up was Larry's Heating and Cooling. I called first thing in the morning and they were able to get someone scheduled to come out the same afternoon. The technician, David, called when he was on his way. He arrived on time, was extremely personable and professional. He is clearly very knowledgeable and experienced in his field. He diagnosed the problem in less than 10 minutes and took the time to show me what the issue was and how it needed to be repaired. Because he needed to come back with a part to get things fixed and the weather was going to cooperate, we scheduled for a week later when we returned from our trip. The day he said he'd be back, he showed up as scheduled and in a couple hours he fixed our unit. Temps dropped below freezing the next day, but our heat worked perfectly so we didn't care. David did a great job! Great team, very competitive pricing; highly recommended. It's who we will call in the future if needed in the future for certain!

They installed a new coil in my indoor unit in Aug 2022 for $2k+, wasn't cooling and had lost gas…read morein April 2024. They did a service call and said my coil was leaking, sent an estimate for full unit replacement only about a week later after I chased them and asked for a warranty repair - they said no warranty after 12 months. Got a second opinion, the SKILLED and HONEST other technician from a different company went to the attic, 15 minutes later said the coil wasn't leaking, but there was a plastic cap that wasn't tight and had oil residue on it - they replaced and tightened the cap, refilled the gas and everything is fixed for a fraction of the price of a new unit. This is my experience with Larry's heating & air, why I will never use them again or recommend them to anyone else. I gave them an opportunity to explain to me what happened and why the problem was misdiagnosed, but haven't heard back from them.

I cannot compliment these guys enough. Our AC went out on Friday evening, before Labor Day weekend…read more I emailed them to see if they do weekend calls. I got an email immediately back from Angela saying that they didn't do calls on a holiday weekend, but have times on Tuesday. While we were sweating most of the time, I was appreciated that they responded and were able to stop at our place the next day they were open (usually, it isn't until the end of the week). Roger and Bobby came out and got right to work. They explained that the unit needed to be cleaned so it could run more efficiently, and they re-filled the Freon. They were quick efficient and explained a lot of the details they were working on. I highly recommend them and would call them back immediately for maintenance or to fix our unit.

This past December we got one of those winter heatwaves that shouldn't happen, and I had to turn on…read moremy home's AC. Shortly thereafter, I found water leaking onto my ceiling. My home warranty assigned Certified to the job. The techs arrived, found a clog in the drain, blew it out, and called it a day. Total time spent: about 10 to 15 minutes. Winter finally set in, so I didn't run the unit for the next few months, but almost as soon as heat arrived, I had the same issue again. After climbing up to look at the unit myself, I found a wet/dry switch that would have tripped the unit before allowing it to overflow. I called my home warranty company, and another contractor identified that the unit had been poorly Frankensteined together and would need to be replaced. Over my objections, since the level of incompetence required to miss the wet/dry switch was astounding, Certified was selected for a second opinion. After 10 minutes in the house, they chalked the entire problem to a valve and low Freon, underbidding the original contractor and getting the job. That was over a week ago. After they failed to return phone calls, I finally managed to arrange an appointment for today between 1 and 4 PM. We received no courtesy call, and when I tried to call the company, apparently nobody was home. 4 PM came and went with no word and no service. It is over 100°F in my bedroom. My fiancee and I are having to sleep downstairs on an air mattress, since it's only in the upper 80s down there and passes for bearable with enough box fans. My indoor dog has been put outside, since it's colder outside than in. I have been over two weeks without AC in Tennessee's summer heat waiting for this company to do their jobs and fix something they failed to find the first time around. I'd say they dropped the ball, but that would imply that they picked it up in the first place. I could not possibly be less satisfied with the abominable service I've experienced from Certified Heating and Cooling of Chattanooga.

They also knew we had a smart thermostat installed prior to the "upgraded" replacement system, but then informed us that this new system cannot support smart thermostats AT ALL. So thousands of dollars for a new system that cannot support smart technology in 2026. I cannot recommend this company at all despite their otherwise stellar reviews.

He was pleasant and very knowledgeable and fixed my problem in two visits. I love working with people who know their craft. He explained to me the exact problem and solved the whole issue immediately. Bill had all of the diagnostic equipment to ensure the unit was operating effectively and efficiently. I was very impressed. I had another Signal Mountain provider first assist me with my A/C unit and they sent some very inexperienced people to add too much Freon to the unit so that it could have caused a complete breakdown. Additionally, I called for them to come out on a different issue they fixed. However, they had to come back a second time for an issue I believe they caused while fixing the first. I spent too much money dealing with inexperienced people from this other company. I would go directly to Superior Air Systems
