JLM replaced my entire HVAC system last week and I'm very happy, so I wanted to write a review…read more They arrived right on time, completed the work ahead of schedule, and walked me through the system and answered all of my questions. 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!

Fast friendly service will be using them for my HVAC needs from now on. Customer for liferead more

Had a bigger Hvac company start servicing my new homes unit- the AC stopped working- the guy came…read moreover and said "it's an electrical wiring thing, but I don't have time to figure out what's wrong. 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.

Nice guys, BUT get ready to overpay for a repair…read more.. They came out to address a noisy/failing inducer motor. They made the repair, and it took them just 1 hour. They charged me $1925 for the repair. I paid the bill, but couldn't understand how the charge was so high. I did some research, even calling the Lennox parts warehouse where they purchased the part. The part costs anywhere from $600-$700. The Lennox parts warehouse couldn't tell me exactly what they paid (w/o their acct #) but said the cost was "not even close" to $1000. That means they charged me over $1200 for an hour of work...unreal. The owner claimed they have a pricing book that dictates their prices - obviously to their significant advantage...not the customers. I asked if he would reconsider their charges, but he would not. Again, they seem like nice guys...but their pricing is very high, and I feel is dishonest. I will not (can't afford to) use them again.

I was really pleased by the process for getting our AC replaced. Matt worked with me on a bid for…read morethe new unit in October, and spoke intelligently about the options, where other companies did not seem as educated on the components. This bid was actually less than the competitors, and they had not been around as long as Harster! It was an easy choice. We scheduled to do the replacement in January. Jim and his team came out to do the install and addressed some additional needs to increase the air flow, make the existing unit up to proper code, and make the filter track so it fit filters appropriately. The last unit installation I'm sure was a DIY job or done by a less qualified company. Jim addressed all those issues. I was on a meeting when he was all finished and didn't get to go see the finished product until after he left. It was beautifully done and very neat.

Harster Heating and Cooling just left my house and I could not wait a second to write a review…read more This company has superior service and timeliness. My furnace stopped working and I called Harster after reading the other reviews on Yelp. The receptionist was very nice and she had a technician out in less than 2 hours. I ended up needing a new system, but two of the nicest and most informative technicians came out the very next day and completed the work. They talked to me about the system and what I can do to maintain it. The price was fair and what they quoted originally did not change after the work had been done. I would recommend this company to anyone.

Pleasant to deal with!…read more My scheduled changed and they were so accommodating they still came over and drew up a quote so I could get this over as soon as possible for my HOA to approve. Communication is good. Staff is very friendly. Quote was very detailed and just what I need for HOA approval. Recommend for any HVAC needs.

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's been years since I've used Doyle, but that's not a bad thing…read more In the past few weeks, I've needed the MB sink not draining, the basement Whirlpool refrigerator (40 years old) not freezing, and the kitchen Whirlpool refrigerator freezer lower basket not opening well. Enter Kevin for the sink, and Bruce for the refrigerator. Kevin fixed the MB sink, which was corroded and needed a replacement drain. Bruce told me the 40-year-old Whirlpool refrigerator in the basement was a loss, as the freon it's using is running out, and no longer available, replaced a long time ago by another coolant. OKEY DOKEY . . . time to get another refrigerator for the basement, but this Whirlpool sure served its 40 years well!! Lastly, Bruce told me the kitchen Whirlpool refrigerator needed new gliders for the freezer basket. I could see how they were not working completely. Bruce ordered the gliders and within a couple weeks, he was here to install said new gliders. They worked perfectly. And Bruce showed me how well that freezer basket was working and actually the whole damn drawer opened . . . something I had never experienced. YIPPEE on all counts!! I still need to contemplate getting a replacement refrigerator for the basement. Nothing fancy at all. Just a plain old refrigerator. We'll see!
