HVAC reviews in Fort Mill, South Carolina

I have been having issues with my a/c, another company assisted me but I called for a check up and assistance with cooling issues and they never called back. I contacted Keller heating and Air, I asked for a better system for my home . Justin walked me through potential options. I got a quick turnaround on a quote and after accepting the offer we scheduled a date for installation. Justin and Ethan arrived early with masks on, and shoes covered. I was given an explanation of the job and expected time of completion. True to their word they finished on time. The owner of the company Glenn stopped by as well . They were efficient, courteous and all business. Justin gave us a tutorial on programming the thermostats (twice). We look forward to cool summers and warm winters! Thanks

Outstanding work and customer service. A family run business that does not take any shortcuts on the job. We have used Keller annually over the past few years for their
furnace and A/C tune ups but just recently needed to replace all the ductwork at our new residence.
I worked with Glenn the owner directly on the logistics/planning and the techs Justin and Jonathan were the ones doing the installation.
They were professional and skilled with this job and always courteous taking their shoes on and off before entering the home. They provided multiple photos of the work updates along the way and even cleaned up some additional debris under the crawlspace that they did not have to do.
The team truly went above and beyond on this. I'd highly recommend Keller Heating and Air.

This was my 3rd time calling them for an issue with my HVAC system. It's always a pleasure dealing with them. I've had a different person each time and they were all great people. Respectful, personable, and kind. Jonathan came this time to fix our outside unit and he is a great stand up guy. It's hard to trust companies these days to not take advantage of you, and I've never had trust issues like that with Keller. They are fast to respond, and very fair on cost. And they'll be straight with you and tell you the truth. I have a little knowledge in this area so it's so refreshing to see honest people tell you how it is. Highly recommend them.

Quick, efficient service provided! When you wake up with no heat on the coldest night, an early morning call was greeted with Kelly and accommodations made to fit me into the schedule. Able to come earlier than original time quoted.
Love supporting family owned businesses and they will continue to be supported by me!
Thank you!

Mike was very informative, concerned, supportive. I will only use his services in the future

Mike was great. He came within the hour of being called and made what would have been a hot summer night into a good, cool sleep.

Literally the best! Installed a new mini split for us on a Saturday to beat the heat.

The nicest, most knowledgeable professional service from a very finicky and detailed homeowner who tried all the rest and wound up with the Best! Way to go Mike. Thank you for your honesty!👌🌞
