"AC Dave is a skilled and trustworthy HVAC company that does quality work at a competitive price. I had an aging four ton system that was on its last leg. My funds were tight at the time, so they suggested installing more efficient ducting to extend the system’s life. That was three years ago, which allowed me to save for the inevitable expense of replacement. And when that time came, I was given a comprehensive estimate and the installation went smoothly. They also did a follow up to tweak the system for maximum reliability. AC Dave is a small company, so you may not get next-day service, but they will work with you and stand by their work. In today’s less and less neighborly world, that is a real asset."

"Worked with Tim - was looking for new HVAC system. He was honest and provided the best price for what you got (literally thousands of dollars cheaper from other options I was finding). Was very communicative and easy to work with. He made sure to educate you on the ins-and-outs of HVAC systems, and did not try to upsell you like other companies might do. He and Efficiency Air definitely got me as a new continued client."
