"Ragsdale services our HVAC system since 2008. Their excellent service record gave us the incentive to include them in a bid with 4 participants. Despite negotiating during a heat wave, Ragsdale's Chris Boyd came through with a winning efficient 2-stage system proposal in one week. We thank the LORD that we will continue to do business with Art Ragsdale's most competent staff. --- Rev. Rob, USMC veteran"

"Hired these guys to replace my original heating and A/C unit. They seem to have done a good job--it works fine. Furnace unit has filter and housing is a little wonky, but it seems to work. They also installed a fancy thermostat which can be read and operated by my phone over the internet. I wasn't too impressed with the thing at first, but I'm away for periods and I've been very pleased with it."

"Bobby came out and installed a complete Trane system and even relocated the furnace and A/C compressor to a more sensible location. The installation crew was polite, professional and efficient. The new heating and air system works flawlessly. Best service I have ever gotten from a HVAC company ever!"

"I had a great experience with Climate Heroes when my HVAC system was not cooling well and was running constantly. Miles was the technician who came out, and he quickly diagnosed the issue and explained what was causing the problem in a way that was easy to understand. He made the necessary cleaning and tune up efficiently, checked the system thoroughly, and made sure everything was working properly before leaving. Miles was professional, knowledgeable, courteous, and respectful of my home throughout the entire visit. I really appreciated his communication and attention to detail, and I would definitely recommend Climate Heroes to anyone needing HVAC service."
