Who We Are

Excellence has been our hallmark since 1954


Diversified Heating & Cooling, Inc. was founded in 1987 as the result of more than 42 years of experience servicing the commercial and industrial market. We recognized that residential housing had become as complex as the industry we were servicing and that our expertise and background would enable us to fulfill these needs as well. So, in 1993, DHC acquired Farmington Hills Heating & Cooling and Northland Heating & Cooling, servicing the residential market since 1957.


To provide full service repair and installation of heating, cooling and associated components to the commercial, industrial and residential market by providing reliable products and services, consistent in quality and value while maintaining integrity and the trust of its' customers with trained and compentant employees, at all levels, who are focused on customer satisfaction in order to provide a reasonable profit for continued growth and stability.

Our company specializes in the design, engineering, and installation of complete comfort systems for owners of existing homes and buildings just like yours. We take special pride in the craftsmen we train and employ--a fact you'll notice immediately in the attitude and integrity they bring to your job site. Our entire company works hard to make your experience with us hassle-free and enjoyable. Should we make a mistake, we will do everything in our power to correct it to your satisfaction.

From the professionalism of our sales engineers, to the dedication of our field personnel, we are committed to delivering you the best. We take our responsibility very seriously when you place your trust in us. We pledge to always tell you up front what your cost will be to complete your job correctly. We make it a point to go over any details or limitations of the proposed system that will affect your enjoyment of the end result. You are told exactly what to expect up front. We back this philosophy with our exclusive written guarantee when choosing Diversified to contract your job:
"If at any time during the first year of installation, you are not 100% satisfied
with the performance of the equipment, our service or even our people,
we will, within 30 days of your request, remove the system and
cheerfully refund the entire amount of the contract."
Compare our guarantee with the limitations, fine print and exclusions other companies tend to use to back their work today. Others will typically guarantee only the functionality of the equipment--not your satisfaction with the process or that the finished job lives up to your expectations. This is why Diversified continues growing with more satisfied customers each and every year. Give us a call for your service needs and see what you've been missing.
