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.

Thank you Brandon Nicholas for fixing my ac unit!! I came home from work yesterday and it was cool…read morein the house. You have no idea how grateful my pets and I are. 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

One was from this business…read more Communication was great however they wanted to come to my home without me there texted to leave door unlocked or a key for them and they would send me an invoice. I was not given a price and I have never met this person. When I declined services due to these things I received "You want me to drive 45 mins spend 1-2 hrs testing the systems for free?" Brandon kept going on and on being demeaning, disrespectful and unprofessional. I was very hostile. I explained further I am not interested due to the cost as I would like to get several quotes and several I have spoken to do not charge a fee. To improve I think this company should meet with homeowners first not try to gain access to their home without them present and be transparent with pricing.

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.....

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...
