Mike’s father owned a heating and air conditioning business. From the time he was 14 years old until he was in college, Mike would help his father during weekends and summer breaks, and that’s where hMike learned the tricks of the trade.

After Mike got married, he decided to start up his own heating and cooling business and opened Hammer’s Heating and Air Conditioning in 1992. Today, he remains committed to personal services that include everything from major installations to minor repairs.
