Since moving into the area we weren't sure who to call when we had AC issues. We like to use local…read morebusinesses and decided to give JLM a try. They have exceeded all of our expectations! The technicians were very knowledgeable, polite and respectful of the property (shoe booties and all). Not only did they know exactly the problem with the outdoor unit, they also helped set up a smart thermostat after installing the part outside. The lead tech even took the time to draw out a diagram of how our heat pump works and why we had the problem that we did. They took the time to make sure that we were satisfied with the work and we were only charged the service call fee and the cost of the part. 100% calling them again for maintenance, services and repairs (but hopefully not too soon).

Backstory: I had gotten a new ac unit installed a year ago but it never ran well so I assumed it was too hot outside, bad windows, insulation issue and had purchased 2 window units to help keep it cold inside. I've known Brandon for a very long time and was just casually complaining about my HVAC issues, then he had me check some things out to find that the previous installer completely did a hack job. I was lectured about using "friends of family" who aren't properly licensed and certified...but then he fixed it for me quickly. The price was very reasonable and the amount of care and thought he put into worrying about me and the dogs meant even more 10 out of 10 would recommend him to anyone requiring HVAC services

He managed to get it working like brand new and saved me a lot of money and stress in the future by improving the air flow!

This review is far overdue. I contacted Shane and his crew a couple of years ago to put in a mini…read moresplit air conditioner on my third floor. It was a big undertaking, with a lot of piping? from the ground up to that space. Shane, the owner, came out within a short period of time to evaluate the space and give me a bid. The crew that came was awesome, respectful, and cleaned up their messes. Shane then came to make sure everything was copacetic. I was so impressed, that I now use them at least twice a year to service my air conditioning, mini split unit as well as my furnace. Speaking of... They always send me reminders when I am due, as I notoriously forget that maintenance which is very important. They definitely come up to the city, not sure how far west they go.

Warning....We are very disappointed in Sam and his lack of ethics. Sam replaced a new water heater…read morefor us February 2024 at our property in St. Louis City, MO. His bid says he is licensed. Not sure that's true. I am having a problem now with water leaking on the floor from an overflow from the heater. Sam talked to us July 3, 2025, we showed him pictures of the issue. Said he would be out asap to check situation. He blew us off. I'm sure because he knew he put it over the drain and blocked it. End of July 2025 and, after calling , texting, my husband calling, texting , I had to call a different company to come out and found out that Sam from Liberty Heating and Air moved the water heater to a different spot and over the drain so now I have to have it moved because water is flooding the basement and we have to put overflow hose in a bucket. This is going to cost$$$ Avoid Sam and Liberty Heating and Air Ridgetop address. He isn't a reputable service. Sam if you see this review and are honorable and properly take care of the problem you caused we will alter the review to reflect your ethics in correcting your mistake. Otherwise.......the value for your service is minus several hundreds of dollars and your name is mud. Shame on you. Well ,Sam is a good guy after all I said. He called me back, went to the property resolved the issue which turned out not to be a mistake he made but rather our tenant moving the overflow drain out of the drain. The other company said the water heater needed to be moved. Sam showed me proof he hadn't moved the location of the water heater from its original spot that it sat on for over 20 years. The other company could have put the drain hose back in the drain but chose not to. Another story. We are happy satisfied customers! I'd recommend Sam he is honorable. A happy ending.....

Bruce was fantastic to work with and talked me through everything he was doing. He gave me some tips on efficiency and how we can extend the life of our unit that is on its way out of this world. I really appreciated the fact that I didn't feel uncomfortable writing the check or like they were trying to screw me on anything. I had a problem a few weeks later with my unit again after a bad storm and Bruce walked me through fixing it over the phone just out of his own kindness. I will absolutely be using them again if we have any more issues and when we get our new unit.

I found after calling 8 places that typically it's hard to get an HVAC technician out on a weekend without usurious weekend fees. Jeremiah picked up my call first try, and was out to my house in 20 minutes. He had everything he needed ready to fix it and I'd say it took him an hour to get everything fixed up. He was cheaper than everywhere I called, and that didn't mean it was lower quality. He fixed the pressure switch and taught me a lot about how to get into the panel and diagnose problems for the future. I'd recommend him to anyone. Especially on a weekend given there was no extra fee!!
