"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!"

He knows alot about AC systems and answered all of my question prior to my purchase.The install crew was very efficient installing a complete AC system. They wasted no time while they were at my home and answered all of my questions. They also made sure that they cleaned up after they were finished."

"Our home AC unit was broken down and needed a replacement ASAP. Trend Mechanics was called and they came the next day to access the problem. The main coils were leaking and they couldn't be fixed. Within a day, Trend Mechanics looked for new Unit, bought it, installed, and filed extended warranty for up to 10 years with the manufacturer. Parts and labors were also guaranteed up to 1 year. We're happy with the price and the services performed at our home. We would use them again next time. Thanks."
