It was very easy to complete the financing process as well. Before it was installed, JLM sat down with me to review all of our available options based on the current status of our system. I feel they are very trustworthy, unlike some other "bigger" companies we've used in the past for service. Highly recommend. Thank you JLM!

Wonderful staff! I called to set up an appointment and was called within the hour and actually had…read moreto push them back to a time I could be there because they could get to me so quickly. 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.

It's too complicated. You need a new system anyway- it's old" said I needed a complete replacement because they can't service my air conditioner anymore - wanted to sell me a $10k unit. Branden came over and did a long look at my unit and agreed that it was an electrical thing- apparently he WAS willing to figure out what was going wrong- got it going again and said when it stops working again to call him so he can figure out where the wiring needed replaced. Spent a long time at my house. Well, it went out a month later and he came over and did everything he could to figure out where the wiring problem was. Took a couple visits and lots of trial fixes. Said he could service my AC just fine in the future and fixed the issue- everything working again. He also has lots of options for when I do need to replace my older system- but it's not now. Very conscientious, very knowledgeable and very patient and tries very hard to fix the problem without taking shortcuts and not wanting to do the work cares more about the customer than making a big sale.

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.....

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.
