"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."

"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!!!!"

"This company is very good. My water heater was beginning to leak and I knew it was time for a replacement and upgrade. Ecoplumbers was able to schedule the day after my initial contact. Ryan offered a quote, explained what he planned to do and installed a new heater within 3 hours. Communication between scheduling services, the service technician (Ryan) and myself was excellent. I am very happy that I used this company"

"First of all I am not easy to satisfy. I run a local roofing and restoration company so I expect a lot. I analyze not only quality but price and customer service as well. Wells HVAC satisfied and even exceeded my expectations. I thought I had a good offer from another provider and I explained to wells that I was ready to pull the trigger with another deal but they came out and offered a better deal with a better warranty at a better price than the one I was going to go with. I was really happy they replaced the system in my Condo. I plan on using them to replace my unit in my other condo when it goes out and possibly the unit in my primary home. You can end your search here and go with Wells. You will be glad you did!
Sincerely,
Jay Thoms
