HVAC reviews in Chattanooga, Tennessee

Great service. Responsive, good value, friendly, helpful techs, staff, and management. We are so pleased we found Larry's/One Source. Highly recommend.

Been using Larry’s Heating and Air since we moved into our house in 2018. One Source is their new name BUT the people and service are still the greatest!! Thank you for always being available when we are in need of help. You’re the best!!!

I cannot express how pleased we are with this team. Courteous, knowledgeable, professional, and most of all FAST RO RESPOND. Each time I have had to call them they respond and are on site within 24 hours.

Great fast service and the tech was great, helped me look up the manual for programming my thermostat and explained everything really well! And he came out like an hour after I called!

Charging $287 for a pound of R32??? That's Tha average cost of a 20lb tank.

I recommend these pro’s to anyone looking for Quality, Quick, Helpful service. A/C down yesterday and they had me cool by early morning. 5-stars in my book!

Wonderful experience from the time I called to schedule an appointment through the technician, Emory, arriving on time and efficiently servicing my heat and air unit.

When we purchased our home last year, the prior owner recommended One Source Heating, Cooling, Plumbing & Electrical- Chattanooga so you might say we inherited them. We’ve been pleased with the heating and cooling service provided by One Source as well as the professionalism of their employees.

Excellent service; very quick response - came within an hour of my call. Technician was very professional. He was knowledgeable and really helped me to understand our air conditioning system and how to troubleshoot if there are problems.

Very pleased with the service I received from this company. The tech they sent out was polite, thorough and professional. He provided tips, references and offer great advice. Would use this company again.

Fantastic service! I would highly recommend them for HVAC service. The technician, Mark, was so friendly and thorough.

I was very happy with their service. They explained everything to me and were very professional.

Service call was reasonable and the tech was great. But the freon charge was considerably more than a competitor charges per pound, via my checking after the fact. In the end the cost was over $100 more than the other well known local hvac service company said they charge.

Mason was good technician, found the problem in a timely manner and gave repair options for a reasonable price.

I called One Source my air conditioner had stopped working in all this heat. The repairman was very professional courteous and honest about my assessment. A few hours later I am up and running full capacity. Thanks for a job well done

Mark is a great technician! He checked out everything and let us know in detail what he did and what needs to be done.Outstanding job!!

I chose this company because of their good reviews for their service, but my experience has been anything but good. It has been a month since my first call, and still have no AC. They say they will be there, but no one shows up and no one calls me to communicate with me. I know they had to order a part, but if this had been handled correctly, it would have been here in a couple of days. This is the poorest customer service that I have ever experienced.

Everything went well. Super nice young man. I was disappointed that I never received a itemized report for all they wanted to do. Im still trying to get one.

Unfortunately the technician was in quite a hurry. I spent $300 for a ‘fix’ that lasted less than 48 hours. I asked questions and was assured of the resolution, so I asked a few more because the unit is only 5 years old and the answers were not adding up. I was told he was certain he ‘fixed’ it. Yet here we are 48 hour later in the same boat. Would not recommend.

5-Star Service That Truly Saved the Day!

After hitting a frustrating dead-end with my home warranty company, I was completely overwhelmed and unsure of what to do next. That’s when Johnathan Brewster and Mason Hays stepped in and I can honestly say they came to the rescue, literally!

From the moment they arrived, they were professional, knowledgeable, and genuinely compassionate about my situation. Johnathan immediately assessed the issue with clarity and confidence, while Mason worked diligently to make sure every step was done thoroughly and correctly. Together, they operated like a well-oiled machine—communicating clearly, working efficiently, and most importantly, treating me and my home with respect and urgency.

What impressed me most was not just their technical expertise, but their willingness to go above and beyond. They didn’t just do the job, they owned the solution. After feeling brushed off by my warranty provider, having Johnathan and Mason take charge brought me immense peace of mind.

If you’re ever in a bind, trust me you want these two on your side. They turned a nightmare into a manageable situation and delivered top-notch service with integrity and care.

I can’t thank them enough!

Our invoice was sent to collection before we received it and had a chance to pay. They didn't email, usp mail, phone call, no communication. They also one the collection company. BUYERS BEWARE!!!!
