We're working to change the landscape of HVAC service providers across the Nashville metropolitan area — by being the company you can trust to give you the straight answer. No upsell pressure, no vague invoices, no part replacements you didn't need.
"Our HVAC quit working on a Saturday when the temperature was 99 degrees outside. After calling half a dozen HVAC Companies, Demetrick was the only person to call us back. He was at our house within 90 minutes, diagnosed the problem within 15 minutes, and thoroughly explained everything throughout the process. I couldn't recommend him and his company strong enough."
"We had a control board go out and he was able to give us a diagnostic the same day. He called around for the part(s) needed and gave us the options that worked best for us relative to price and timing. Once the part came in, he came to us after business hours to install it. Proud and pleased to support a small business owner who is honest, responsive, and fairly priced."
"I can write a book on the customer service. Demetric came out, assessed the problem, went way beyond and above to get the issue resolved. Where I know that a big company would have just charged you for a new unit. Not Demetric! He will try every trick that he knows and will also consult with other techs to solve your problem. Bottom line, he is compassionate about his business and the people that hire him."
Whether it's a no-cool emergency or a planned upgrade, our process is the same: fast, transparent, and on your schedule.
