Excellent, the gentlemen that came out to replace my Air and Heat were very professional, they even answered a few questions I had. I will recommend you folks if someone needs help. Thanks again.
Trustworthy. Great company, very responsive, very informative, and do great work. I have used them at two different locations and had the same impeccable service.
They arrived on time and were professional, and friendly, and did a phenomenal job of cleaning up after they were finished …. even swept up my mess in the garage. Honest and great work from Hardin’s Heating & Cooling
Excellent professional service from getting an estimate to having a new AC/furnace installed. The installation team arrived on time, explained the installation, and cleaned up the area completely when they finished. Definitely will refer Hardins for great service.
Jess with Hardin’s Heating & Air was very thorough and professional. I appreciated the same-day service. I will continue to use and refer to Hardin’s Heating & Air.
Every service call/interaction I’ve had with Hardin’s Heating & Cooling has been fantastic! Great attitudes, communication, and trade professionalism!
When it comes to heating and cooling for my house, I only call Hardin’s Heating & Cooling!
Thank you Hardin’s Heating & Cooling for your efficient and excellent service. They replaced our unit after the other had died. We would not have survived the summer without you. God bless.
Previous repair was again making a similar noise as before; the return call was quick, the technician arrived when we were told, and the repair was still under warranty. Appreciate their service and will continue to use them for our HVAC needs.
This is a good company to deal with. They are locally owned and you get to communicate with the owner as needed. I got a completely new heat and air system and so far, so good. It runs more quietly and has a good warranty. They send out a crew of highly skilled technicians and get the job done right.
