"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."

"This company is fantastic. I had a mess in a home we bought to rehab. These folks cleaned the ducts, but saved me $4,000+ dollars on various things they found that were serious issues, that were not related to the ducts. Even found a place where a previous installer for my water heater set me up for a fire. These folks are fantastic. $700 cleaning, $3300 saved!!!!"
