Our History

Greenleaf Heating & Cooling was founded way back in the early 1970’s. At the time, we had just 3 employees. We were also mainly selling appliances. That all changed in January of 1977, though. This is when we entered the air conditioning and heating business.

At first, we focused solely on residential business. As our company and our reputation grew, though, we moved into the commercial sector as well. Now, we are a full service commercial, residential, and industrial HVAC company, with 15 employees on the team.

Why Work with Us?

There are a few reasons why we are able to succeed at the level that we do, with every job that we complete. One is, of course, the quality of our employees and technicians. Perhaps more important, though, is the way in which these employees interact with one another.

We have one of the most complete installation and service departments that you’ll find, all working together. Our office personnel are happy and committed, operating as much like a family as a company. That feeling extends to our customer base, as well.

Our Claims to Fame

We do a lot of things well around here, but our claim to fame with our residential customers is that we leave the house cleaner than when we arrived once the job is done. Sometimes contractors get calls after a job is completed that deal with shortcomings. We most frequently get calls from pleased customers.

Our commercial clients have much the same experience. When you own and operate a commercial property, time is usually very valuable. We always show up when we say we are going to, and we always come prepared and do the work we say we will. That punctuality and preparedness leaves our clientele coming back time and time again.
