“When our AC started acting up during the first warm stretch of the season here in Charleston, I was stressed thinking it might be a major (and expensive) issue. Pros Heating and Air showed up quickly and immediately put us at ease. They took the time to explain everything clearly, walked us through what was actually going on, and made the repair without pushing any unnecessary fixes. What really stood out was their honesty and how genuinely helpful they were. They saved us a lot of money and made what could’ve been a stressful situation feel completely manageable. So grateful we found them!“

“Kyle was our service technician both for the initial service to take a look at the unit to see what was going on, and again for the service to fix the issue. He very communicative and always explained what was going on and what he was doing to repair it. He was personable and respectful throughout the entire process.“

“I can’t recommend O&R more highly. Affordable, friendly, professional and great service. They even helped me out by changing my filters for me. I have great peace of mind knowing O&R are there when I call.“

“In 30 years of property management hands down the best HVAC company I have ever worked with!“

“I highly recommend this company!! I have used them for 17 years. They are so honest and reputable. I used them when I lived on James Island and on Johns Island. They are very honest. I always had a contract with them and came twice a year to service my HVAC system. In both homes I only had minor problems and they never ripped me off.

I just had a problem with my A/C on the weekend and their technician came out next day on a Sunday! He fixed the problem temporarily so I could have A/C until they could order the part. They called me Monday to tell me they would come out Wednesday to replace the part. In this day and age it’s very hard to find a company that one can trust. If you had problems in the past with your HVAC company in the past I highly recommend Smith Heating and Air.“

“My dryer vent was in need of cleaning, we called The Allergy Shop on Friday and Norm arrived on Saturday. He was professional and expeditious. Norm cleaned our duct work several years ago. I would recommend their services to all.“

“BEST Service and Quality I've ever experienced from a service company. They were easy to coordinate and schedule with great communication. Fast service and excellent pricing. Would highly recommend to anyone needing service on their HVAC or install a new unit!“

“This Guy is very professional and knows what He's doing...I Highly recommend Him 100%“
