Pleased Customers

  • Excellent service for my annual tune up. Dan explained everything that he was was doing and the results. Very professional and I would not hesitate to ask for him for future services!

    James, St Petersburg

  • Dale was extremely helpful and did an outstanding job repairing our compressor wiring.

    Mark, Palm Harbor

  • “Thank you so much for the new Carrier AC unit! Your service department and technician were stellar. So professional, thorough, and informative. A nice change of pace, and unfortunately not the norm these days. Doug really helped me understand the problem with my system and took the time to explain what he found. Michelle really made the whole sales and purchase of my new unit a comfortable experience. And your installers… Outstanding! Both were great, leaving absolutely no mess behind. Actually my garage looks better than ever because they found some paint in the garage, and unbeknownst to me, touched up the walls around the install – making things look like new.”

    -Cherly, FL

  • “The technician was extremely helpful. He answered my questions and checked everything. We have had problems with sprinklers rusting out air conditioners in our condo. He took a hose and washed down the air conditioner. He took extra care and explained things and pressure cleaned the drain outlet. Excellent technician. Thank you.”

    -Mary, Largo

  • “Bruce seems very knowledgeable and always helpful. He is careful to cleanup when his work is completed and he does not come into the house all dirty. An asset to your Company.”

    -Richard, Seminole

  • “Bryan made an earlier call based on our conversation at the Home Show. He suggested a plan which I followed-up with Dale. Both were exceptionally competent, straightforward, and professional. I got clear honest answers to my questions. I’m sold on United. I will continue to use your services in the future and will recommend you to everyone. Thank you for the excellent service.”

    -Robert, Clearwater, FL

  • “The response to our immediate need for a service tech was handled with the utmost professional courtesy to help resolve the problem. We have known United Air for many years, and hold the company in high regard. Thanks for the service you provided.”

    -Edward, Palm Harbor

  • “Dear John, Just wanted to let you know that our new system is installed and working perfectly! We couldn’t be happier with the entire experience of working with your company. Your technicians, Eddie and Ron, were here right on time this morning. They were professional, courteous, helpful, and a pleasure to do business with. With employees like that working at United, I’d say you must have a great staff and workplace! Your company is officially on my iPhone contact list! Thank you,

    -Yvonne, FL

  • “What a great experience! After our 16 year old Trane HVAC Unit finally quit on us, we set out to get a few estimates. United was the most professional, but also realistic presentation. Having a tight budget, Brian was sensitive to our situation and was honest about what we needed. He was clear, concise, and on time for the appointment and answered all our questions. The install guys were very nice, appropriate, and respectful. The owner Jerry even stopped by to see the install and say hi to me… I was floored. What a nice group. Definitely a keeper. I would recommend them to everyone.”

    -Catherine, Tarpon Springs

  • “The technician Doug was efficient and professional. He quickly found the problem, programmed the thermostat, and did a quick check of the outdoor unit. A prior company wanted to sell me a new system. I was very pleased with the quick response to my call and the honest service. Will definitely do business with United again.”

    -Christopher, St. Petersburg

  • “Tech did an excellent job in showing that the cooling coils were matted with animal fur and need cleaning for best air movement over coils. As a client since 1993, same excellent service as usual.”

    -Joe, Tampa

  • “Thank you for the great service! Will definitely return for any of my future needs.”

    -Edward, Palm Harbor

  • “The whole crew were excellent and they never stopped. Even ate lunch while working.”

    – Don, Clearwater

  • “I am completely satisfied with all processes of my purchase. They were prompt, used time effectively & were very easy to contact and get answers”

    – Judy, Dunedin
