"Dave had stellar customer service! He was prompt and communicated everything to us in a timely manner, even contacting us after hours to ensure he would be able to provide services the next day. He is extremely kind and hard working. Our AC is working better than ever, despite numerous attempts by another company to fix it. He will be my first call any time I need my HVAC system repaired in the future."
"10/10 highly recommend. Seriously guys — David is awesome! He came quickly and resolved our issue expeditiously. He was timely, professional, and courteous. Will definitely use David and the Dave Does Air team again!!"
"Trust, but verify. That's why I always get a 2nd quote. I now trust Dave! 1st estimate very high. 2nd estimate the guy said I needed a complete new system. Dave replaced the capacitor, checked entire system and our air is back to cold. If you need A/C repair or replacement, get a couple estimates, and make sure one of them is Dave."
"We had Dave Does Air out to our home in Del Webb Nocatee to help with indoor comfort and humidity issues. Florida homes definitely deal with moisture and airflow challenges, and David took the time to explain what was happening and what could be done to improve it. He was professional, knowledgeable, and easy to communicate with throughout the visit. The recommendations made sense, and we noticed an improvement in overall comfort shortly after. It was refreshing to work with a local company that focuses on clear communication rather than pressure or upselling. Highly recommend Dave Does Air for anyone in Nocatee dealing with indoor air quality or comfort concerns."
"Dave installed four mini-splits for us in our large garage and workshops. He was fair-priced, worked hard, and was a wonderful communicator. I will use him again in the future for our HVAC needs."
"I highly recommend Dave Does Air. David is extremely knowledgeable and professional. David was punctual, polite and communicated well. He took the time to explain the service that my cooling/heating system needed and completed the job in no time."
