MGM Mechanical, Inc. has been servicing and installing heating and cooling equipment in homes, small businesses, and churches since 2000. Our part-time business turned full-time in early 2017, all due to Mike and his team’s hard work, and more importantly, loyal customers.  We take great pride in knowing 80% of our install work comes from referrals from happy customers.

MGM is owned by Michael Messimer, of Liverpool, PA. Mike has been working in the HVAC field for 25 years, both in the commercial and residential setting, after graduating from York Technical Institute in 1995.

Our team has grown from one employee (Mike) to six service techs/installers in the past 3 years.  Jeremy, Joe, Meade, Richard, Jason, Eric and Chase have time and time again been described by our customers as hard working, conscientious, professional and knowledgeable.

Specializing in Mitsubishi Mini-Split Systems

Our company specializes in Mitsubishi ductless Mini-Split systems.  We hang our hat on this brand due to efficiency and dependability.  With few breakdowns and a 12 year warranty, it is no wonder Mitsubishi is the leader in ductless systems.  Mitsubishi has also developed ducted heat pumps that are becoming a more efficient alternative to a standard Heat Pump system.
