"George and his crew replaced my 27-year-old heater and A/C, and did an amazing job! The job included putting in a new digital thermostat. They even completely lined the inside of the little shed that houses the heater with insulation — which it never had before. They completed this big project in just a single day! I am extremely happy and satisfied with the work and highly recommend this company!"

"Nathan is very experienced and knowledgeable. He responds quickly to every text and phone call. He and his crew show up on time, work diligently, are respectful, and focused, and do all the little details like caulking and matching paint. They installed a 5 unit mini-split system and totally completed in 2 days. The price was very good and he even passed on the incentive from the manufacturer. There are always unexpected hiccups in every construction / installation job and there was no complaining, no extra charges, he just handled them quickly and efficiently. All in all, excellent work, excellent service. We highly recommend NT Electric and HVAC."

"True Air Mechanical is a very great company to work with. Pete our salesman was so very helpful, and patient with us. He was concerned about finding the right system and cost effectiveness for us since we are on a fixed income. He was not a pushy salesman and gave us time to do more investigation. Brian our installer was professional, perfectionist and such a pleasure to work with. He explained all aspects of the system. True Air recommended Carrier system, heat pump and ac unit."
