Our ‘Humble’ Beginnings

My grandfather started our company in 1962, and my father ran it before me. We are a customer service-oriented company that focuses on reliable, friendly, lightning-fast service.  My grandfather, Frank A. Brewer, was a U.S. Navy gunner and served in WWII. He worked for Holland Furnace for 20 years before leaving to start this business in 1962.  Greg S. Brewer, my father, was second owner; he started the philosophy of helping youth athletics in our community. This year, we sponsored over 25 Little League baseball teams with donations and other support.  I started in this business as a young man, with my father putting me in crawl spaces to run ductwork while on summer vacation from school. I started working full time at the age of 19. I obtained my state commercial license at 25. I have three kids and a wife, and I love boating, fishing and hunting.

Thermostats

What is the single easiest way to get higher performance from your existing heating and cooling system while lowering your home’s overall energy costs? Simply install an Aprilaire Programmable Thermostat. According to the U.S. Environmental Protection Agency, a programmable thermostat can save you up to 30% on energy costs annually.  But if you’re interested in getting the very best in temperature control for every room in your home, the Aprilaire Zoned Comfort Control system is your answer. Instead of using just one thermostat for your entire home, the Aprilaire Zoned Comfort Control system uses multiple thermostats to ensure optimum temperature levels and total comfort in every room of your home.
