Heating and Air

Brennan is an authorized Carrier dealer but we work on most heating and A/C brands. We will even work on your oil burner. We manufacture our own ductwork and fittings. We can design a system to fit your comfort level, and once our installers have left, you won't know we have been there until you go to your thermostat. And it doesn't end there, our Carrier trained technicians will be there for any emergency that may arise.

Owner Mike Sieving and technician Mike Matrisch install Carrier furnaces for school district 117.	This is a typical heating and air system with accessories.
