“Kyle is very knowledgeable, he did a great job explaining everything he was doing while replacing my condensation pump and light bulb for UV. He also told me about how beneficial it is to have the club membership that services the cooling and heating unit once a year and offers other discounts and perks.”

“I honestly never leave reviews but I was pleasantly surprised by this company. I had a previous HVAC company out before that was terrible, but when our air went out we needed a fix immediately. They came the same day and honestly did more than I expected. Our technician was Kevin and he did great work. Prices are set, and standard which I like. Based on my experience and service, we’re now looking at making them our regular maintenance company for our HVAC needs.”

“We had an electrical short which smoked. Duggan had a serviceman here in less than an hour. He was professional, thorough and resolved the problem quickly. He had to replace the relay in our air conditioning and add more Freon for cooling. We were fortunate the shorted relay did not blow our motor.”

“Spencer was very kind while delivering news I didn't want to hear but knew was coming. The condenser on a 17 year old system was toast and though it could have been replaced, in the long run that was not the best alternative. A day later, the new system was installed.”
