I recently had mini-splits installed by Northern Climate HVAC. They were highly professional, very thoughtful about placement of the units and explained everything thoroughly. I am completely impressed by the finished job and I highly recommend this company.

Called for an A/C Service call. Voice mail said to leave a text msg. Did so but never got a call or text back. Amazes me that companies actually will blow off paying customers like that.

Just completed a whole system replacement including new boiler, water tank, 2 air handlers, 2 condensers/heat pumps and a new third HVAC zone with all dampers and controls. Excellent communication, always there when he said he would be, very detail oriented and spent extra time making sure the control panel setup was correct. And... NEAT... always left the work areas clean and vacuumed at the end of each day. Can't say enough how impressed I am with Matt from start to finish. I highly recommend.

I recently had Northern Climate install a ductless AC system in my home. From estimation of the job through the install completion I couldn't have asked for a better experience. Matt was thoughtful through the "design" phase and provided expert knowledge to help me decide upon the right system sizing and layout. The install was done within the timeframe he quoted and was done beautifully. He even returned after the electricians wired the unit to turn the system on and show me how the thermostat worked. Thoroughly professional & knowledgeable - I'd give 10 stars if I could!

Matt from Northern Climate HVAC Inc did an excellent job installing my mini split AC/heating system. Every step of the process from the estimate to the job's completion Matt was punctual and extremely professional. The job got done within the timeline given and on budget with no added fees. I would highly recommend this contractor.
