“I had an emergency HVAC issue and called One Hour Air Conditioning and Heating. Nick (largo) came out right away and was fantastic! He was professional, courteous, and really took the time to explain what was going on with my system. Despite the late hour, he was prompt and had everything fixed quickly, ensuring my home was comfortable again. I truly appreciated his expertise and dedication to providing top-notch service. I highly recommend Nick and One Hour Air Conditioning and Heating for anyone in need of reliable, high-quality service. Five stars all the way!”

“Called on a whim with a clogged drain line and received same day service. My technician was Nick and he was awesome! Extremely professional and knowledgeable. I was very pleased with his work and signed up for annual service plan. So happy I made the switch from my other HVAC company!”

“Nick: Amiable and thorough. Previous company said the blower motor needed to be replaced, ($1500) Nick did a detailed step by step diagnosis, explaining everything as he went along. Problem, loose connection, blower motor works. Continued to do a detailed check of the complete system. Made prudent recommendations and why. Thank you. Steve R.”

“Nick was absolutely fantastic! I have been having issues with my heating and cooling for months. There would be power one second and none the next and many times it was if there was a power outage or "blip" or if I needed to turn off any of the breakers at my electrical panel then there would be no power to the thermostat again. I would replace the thermostat and the cycle would repeat. I was concerned that the issue was electrical in nature, rather than the thermostat as previous company's technicians had informed me & they kept telling me to continually replace the thermostat. But, I had already replaced the thermostat multiple times with different brands and was having the same issues repeatedly. So I called 1 Hour Air Conditioning & Heating & they set an appointment for the following morning. Unfortunately, I do not remember the name of the lady whom I spoke with on the phone to explain my issue to schedule the appointment but she was also extremely patient and kind and deserves recognition! (For some reason, I think her name may have been Jordan? But I could be wrong and I apologize if I am.) Our technician was Nick and he arrived first thing in the morning. He listened to all of my concerns and diagnosed the issues in a quick and timely manner. He was pleasant and patient, even with my dog! He explained everything in detail to me about the issues with my breaker. I was so relieved to have a technician treat me with respect and help to get our system up and running again. He also informed me about their program for replacing my 22 year old system and I will definitely be calling them when I'm ready for that step! I would recommend the company and technician to everyone! Thank you all so much!”
