His professionalism and dedication truly stand out, and I can't say enough about the quality of his work. I highly recommended! I checked around and was disappointed with several companies that tried to charge astronomical prices just to diagnose a problem and then some didn't want to do the work but just collect diagnostics fees. Johnson's Heating and Cooling was completely different...they were a breath of fresh air.

Upcoming Father's Day weekend and AC broke on us. We took a chance and called Killman. They were so…read moreresponsive and where others said they couldn't fix the unit until 5 days later, Killman was out the next day installing the new unit. The owner came by and met us and was so genuine and friendly. Just good people. We had a slight issue afterward with a blocked drain. Called them and they came out the next day (on a Saturday morning no less) and fixed the issue. Would highly recommend this company.

They did not try to oversell me like some of the other HVAC companies and their recommendations were exactly what I needed. Recently we had some issues with the ductwork/damper and they came out the next day to inspect it and make sure the new HVAC unit was running correctly. Next day service is rare for such a minor issue. Killman Heating & Air is a class act.

Outstanding Service from Start to Finish!…read more I reached out to TrueClimate HVAC early yesterday morning and was honestly surprised to get a same-day appointment! By 3:30 p.m., "Q" was onsite -- professional, courteous, and every bit what you'd hope for from a true pro. After giving me a quick overview of the company and the process, Q jumped right into diagnosing the problem. Within about an hour, he pinpointed the issue, broke down all the electrical jargon so l could easily understand it, and clearly explained the repair options and pricing. He returned the next day exactly when promised, got straight to work, and within 30-40 minutes everything was repaired, cleaned up, and working perfectly. Huge kudos to Q and the entire TrueClimate HVAC team -- you've earned a lifetime customer. Highly recommend this company for anyone looking for professional, prompt, and reliable HVAC service!

UPDATE... Today I received a threat to sue from the "owner" of this establishment. Yes you came to…read moremy home and provided INTIAL SERVICE to my HVAC System but I didn't mention in my review here on Yelp that you also left me overnight October 31, 2025, in the Freezing Cold on one of the coldest nights in South Carolina because you forgot to turn the Service back on once you cleaned my system and when I contacted you you stated you would return "first thing in the morning" for that SERVICE you were PAID $1604.58! On the day of service you proceeded to ask if I wanted to purchase a maintenance agreement which included emergency service I agreed. You FAILED to provide the service in that agreed upon agreement. After repeated attempts at "Emergency Service" per your agreement you failed to provide said service! I asked you to cancel that agreement and refund my money and you stated I had already used the bulk of the service agreement and you would only refund $375. Hummmm I contacted my credit card company and after going back and forth with you and me last week they AGREED with me and credited my account $1600 from the TOTAL I PAID IN FULL TO YOU OF $3204.58! Now this morning you send me a text threatening to take me to court! GO AHEAD I'LL SEE YOU IN COURT!! BUT IN THE MEANTIME DO NOT CONTACT ME ANYMORE!! Ohhh and feel free to take this up with CHASE Bank and it's affiliates as they are the one who heard your Side and heard mine and CREDITED MY ACCOUNT $1600! Mahalo

Let me start by saying that I'm sure these guys do great work, and almost apologizing for this poor…read morereview. That said, I purchased a home last spring and have spent more than 7 months now (reached out in August, it is now mid-March) trying to successfully transfer the warrantee to my name. The system in my home has (thankfully) worked great and I believe these guys did it, so hey, good for them. But my polite follow-up, about once a month or so to check in, has gradually led to being ignored. If that's the way this company does business, I can't in good faith recommend them. Would actually be overjoyed to amend this poor review with a simple resolution to an issue that I reached out about in August and was told "the paperwork is in the mail" in October. It's March. As a first-time homeowner, I'm confused and disappointed to say the least.

I had to keep calling them back for well over a month and they never would return to fix the unit. Ended up calling a different company to fix the unit. Needless to say, I had some really upset renters. About 5 months later I received a bill and continue to receive one to this day. I'm really not sure about paying someone for doing nothing.
