About Us


Michael J. Williams, Inc. was established in 1988 and has been in business for the past 29 years. We are an owner operated business and all mechanical work on equipment is done by Michael.

Michael graduated in 1981, and entered the field in 1983, so with 34 years of experience, you can be sure he will get the job done quickly and correctly.

Although he entered the field in '83, Michael continues to stay up to date with the latest heating and cooling technologies as they enter the market to ensure that his customers get the service they need. When installing a new component or system, he always makes sure that the technology has a proven performance record in the field, leaving nothing to chance.

Our success over the years is due to our loyal customers, and for that we hope to continue to provide you with the highest level of workmanship and customer service for many years to come!
