"Extreme Heating and Air Conditioning installed an 18 SEER HVAC system with zone control for me. I am very pleased with the results and performance of the system - far better than the previous system WRT air flow balance. All personnel were very knowledgeable and professional and I highly recommend this company. Thanks to Tristan, Brett, Ryan, Joe, Paul and special thanks to Dave and Tyler for working through some parts failures. I am very pleased."

"Pretty good experience if you just install new HVAC. But, if it is full HVAC and duck replacement, you will need to ask during quote. Otherwise, you will have trouble."

"Our technician called to let me know he was running behind by about an hour. He was very apologetic and professional about the inconvenience. When he arrived he was very professional and got right to work. After servicing our unit and going over all the testing results with us, he made sure we fully understood everything and were comfortable with the results. He was great with our twin toddlers also, who were very interested in what he was doing. Even though it was late and we were his last stop of the day, he stayed and chatted with us and answered all our crazy HVAC questions that had nothing to do with what he was there to do. He was very knowledgeable about his field, was very friendly, and did a great job cleaning up our AC unit. It is running more efficiently now, and I'm sure we will see the results in our upcoming bills! It was an excellent experience and we will definitely use Wells for our future HVAC needs.
