Weaver History


 Weaver Heating & Cooling, Inc. is located at 59851 Elm Circle in Mishawaka, IN.

Weaver Heating & Cooling was established in 1972 by Donald Weaver, owner of Weaver Electric & Heating Corp.

Don separated the electric division and heating division in 1992, when he sold the heating division to Robert Hatfield.

In 1999 Robert sold the business to Jeffrey A. Ness, owner of A-1 Heating & Cooling in neighboring New Carlisle, IN. He then merged the two companies together continuing the family owned and operated tradition.

Jeff has more than 45 years of experience in the heating and cooling industry. He continues honing his skills by participating in training seminars and schooling yearly.

He insists his technicians do the same. Jeff prides himself on being educated, honest and dependable.

He expects the same from his employees. Jeff along with his staff has received several dealer of the year awards and customer care awards for our excellent customer service and high standards.

Jeff likes to set goals to improve yearly. He and his staff usually go above and beyond that goal every year. He has raised and trained his daughter Amy to be the same.

With Amy leading the way, Weaver Heating & Cooling, Inc. will prosper and grow in the years to come.

We were without heat for 5 days and were working with another company to have our heat fixed. They were not able to fix out heat for ANOTHER day so I started calling around to other heating companies and came across Weaver Heating and Cooling.

We’ve been a customer for many years. Weaver has installed our furnace and air conditioner and we use the annual service agreement for fall (heating) and spring (air). They are very professional, helpful and provide prompt service. We highly recommend them!
