    Customer for 20 years good service. Today technician was Daniel complete pm on AC. He also provided us with some necessary repairs for parts for AC & Gas Furnace. Our units under warranty so we only pay for labor. Prices are higher for labor, but so is everything else today.

    Our Technician John was very thorough, he explained everything he was doing , he checked everything with our HVAC SYSTEM. Our thermostat wasn’t working properly. He fixed everything and made helpful suggestions. We have had Academy Air for years, using all of their services and have been very pleased

    Im on a HVAC maintenance plan with SWISS Air and just had my Spring service done by Bill L and his assistant Cody, these guys were great! They took their time, were VERY thorough and very polite & professional. I normally keep a close eye on my HVAC system, but they still found a few issues that I was not tracking. Thank goodness, because the summer heat is about to start and they easily saved me hundreds of dollars in repairs. Thank you for the excellent service!
