"Our annual HVAC inspection went flawlessly. The technician was thorough, friendly, and gave helpful maintenance tips. System is running better than it has in years."

"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."

"This review is about Air Duct Professionals and I want you to know that I finally found a company that was honest and professional. Because when I was at the end of my wits trying to figure out who was telling me the truth, I called Ed Mack the owner and he was reassuring that my home was not that old to be having all these problems. He referred me to a website for the Air Duct Cleaners Association and read about what air duct cleaning really does. So I had Air Duct Professionals come out to the inspection and they have an actual HVAC guy on their staff. Immediately looking at how new and well maintained our air system was in the attic, he told us those other companies were trying to scam us. Air Duct Professionals did a great job cleaning out all of our air ducts and dryer vent and cleaning up after themselves. I whole-heartedly recommend this company for their professional work and honesty."

"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."

"My HVAC unit stopped producing heat so I called the folks at around the clock. They offered to come out the same day and after taking a look up on our roof determined it was a faulty control board. We talked a little about the lifespan of the unit and that while it was probably going to need to be replaced in the next 5 years or so, it made more sense to simply replace the board today. So he scheduled an appointment for the following day to come back with the replacement board. 1 day later and 15 minutes of work and I have heat again."

"At 600 am on a friday morning, I got on the Angi app to look for a swamp cooler expert. At 630 am I recived a phone call from Joel from "Just be cool supply." After expalining the job i needed done, he was able to come over later that day. Sunday morning he showed up removed a useless window and installed a new swamp cooler. Joel and his crew did an Amazing job! Very fast, friendly, good priced, and Profesional. I will be calling joel for all my HVAC needs in the future."
