Do not use this company. They are the most dishonest heating and AC company serving the Grand…read moreStrand of South Carolina. They strive to sell as many new HVAC units as possible by fraudulently telling you your current unit is beyond repair and must be replaced. Then they incorrectly install your new until, leaving you at risk for an electrical fire. They also install it in such a way that it will quickly suffer damage from condensation that they should have installed buffers to protect it from. Then, six months later, they begin telling you about the rust damage (from what they fail to do during installation) and suggest costly steps you need to take to repair the damage. You will begin dreading their twice yearly visits because they will try to convince you each time that there is another $5,000 part replacement or modification that you must have if you don't want to have to replace the entire unit very soon. It's a nightmare so don't put yourself through it.

His straightforward, witty, and deeply experienced approach never felt salesy, just genuinely helpful. Once we decided to move forward, Larry and his team handled the installation with real care and professionalism, working in the attic, outside, and on all the ductwork, vents, and a thermostat that integrates perfectly with our smart home. Everything went smoothly, and the results speak for themselves. We'd happily recommend ASAP Heating & Cooling to anyone.

I cannot recommend this company enough…read more Not only was their scheduling on point but......... As a female I always anticipate being treated as such when it comes to mechanics. However, Brandon took the time to explain in detail the issues at hand and was very friendly and honest. Long story short we ended up needing to replace our unit, within 2 days of the initial service call and a VERY HOT 12 hour install our air is better than ever and for a very reasonable price. These guys could have easily told me that they were done for the day and would need to return but they stayed and finished the job. (we had space issues within the attic which is why the install was so long) On top of the honest, quality work that Brandon and Lance provide they are a veteran owned company which we were happy to support and so very glad that we did. GREAT GUYS AND GREAT COMPANY!!!!!

I will definitely recommend them to people I know and call them again for HVAC issues. I've actually scheduled a maintenance service for next week. Great rate for regular maintenance can't be beat.

The unit was draining out of the top emergency run off and then dripped into our drywall. We stopped using it when that happened (scary) and since we bought are home recently we had a home "warranty" (using that very loosely). I called the warranty company and they had only one hvac company they contracted with and that company was booked solid for 2 weeks. UM NOOOOOO. So I insisted on using someone I found and submitting for reimbursement on my own. I called 2 hvac places and one went straight to voicemail and one the lady heard what we needed and said you should call someone else we are booked. I THEN called Buchanan and I WILL NEVER USE ANOTHER HVAC COMPANY. THEY ARE THE BEST. Brenda in the office/dispatch was really friendly and knowledgeable. She went the extra mile and called my warranty company to tell them the diagnosis. Mike who came out two times what honest, friendly, hard working and we learned a lot from him. The final visit, Vince the owner came out and he was very nice, efficient and took time to explain what was going on. Turns out our ellusive problem child a/c unit just needed Buchanan to come and get her on the straight and narrow. :)

In July 2026, we called into EnerVation asking for help, our AC would not cool the house below 80 degrees. They came out that night and found that our system had no refrigerant. Long story but our 12yr old attic unit had a large leak and was not repairable. They provided multiple options for the repair but we choose a complete replacement. EnerVation replaced our entire HVAC system (furnace, AC, zoning) and did a fantastic job from start to finish. They were professional, on time, and kept our home clean throughout the whole install. They caught a mold issue in our old ductwork we didn't even know about and fixed it properly instead of cutting corners. Everything was explained clearly, they followed up to make sure the system was running right, and the new setup is quiet and works great. Would absolutely use them again.

Our technician, Anthony, was extremely thorough and professional. He diagnosed a failed capacitor along with several other issues and took the time to explain everything clearly. He also let us know that our AC unit is 26 years old and that most systems typically last 20-30 years, so while it was repairable, we should expect to replace it in the future. We decided to repair the unit for now, fully understanding that we'll eventually need to install a new system. After completing the work, Anthony sent us a detailed email outlining everything he had done, along with photos of the repairs, which we really appreciated. We were extremely pleased with the service, professionalism, and communication throughout the entire process. When the time comes to replace our AC unit, EnerVation Heating & Air Conditioning will definitely be the company we call. Thank you, Anthony and the EnerVation team, for a great experience!
