“Climate Zone. HVAC replacement and additional ductwork in family room and three bathrooms. Heat pump + natural gas backup furnace. Been living with it for a while now but if this dies when I'm stlil in this house I'll get it done right.”
“Try these guys: https://www.climatezone.biz They are solid and usually will match pricing, so I would get a couple quotes and see if they will match the lowest.”
“I had really good experiences with both Climate Zone (https://www.climatezone.biz/) and Chilli Willie (https://chilliwilliemechanical.com/) this summer during emergencies. Several of my neighbors have used Climate Zone and recommend them, too.”
Mike & drew came by today. They were efficient and explained everything to me in detail. 10/10
Mike and Drew came to do our 1 year checkup and filter change on our heating and cooling system. They were respectful of our house and protected their footwear from any dirt or damage to our carpets. They were in and out within an hour and ran through all the details with me before leaving on the work they accomplished. Professional servicemen.
Nice work! Very quick! Very professional! Look for those guys Manasseh, Jay , Anthony , Raymond. They are good!
Manasseh, Anthony, Joey & Noel did a terrific job installing our mini split. Crew was polite, informative and helpful. The process was very easy. Sales rep Sam E coordinated the work making the process very easy.
These installers Manasseh, Joey, Anthony, Lincoln, Sam and Ray were awesome!! Friendly, knowledgeable, cleaned up nicely, worked efficiently and instructed us clearly. Love our ac from Climate Zone.
