History of Butler M-K Heating and Cooling, Inc.


Butler Mutz was established on May 1, 1968 by Charlie Butler and Tom Mutz (original Owners).

Larry "Sam" Muterspaugh came to work for them on July 9, 1968. As Sam worked his way up the organization ladder from mail collecting to Vice-President, he has accumulated a wealth of knowledge to help you, the customer.

On February, 2nd 1992, Butler Mutz changed to Butler M-K and the name it is today with the same quality that had been established back in 1968.

In May, 1996, Sam brought in his son Gabe Muterspaugh to continue to tradition of excellence in service, installations and customer service.

Sam and Gabe bought everyone else out in July 1998 and have established Butler M-K Heating and Cooling as a family owned business built on customer service of the highest quality. In SEPT of 1998, Nate Muterspaugh was brought in to run the service side of the business and coordinate calls. Nate is the one you you talk to every day on the phone.

Butler M-K strives everyday to provide each customer the quality the deserve and want. We are a family owned company that when you call in, you get one of us EACH and every day. We are not an out of town conglomerate who only looks at the bottom line. We look at you, the customer as our driving source of success.
