Who We Are

From the professionalism of our sales engineers, to the dedication of our field personnel, we are dedicated 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 McDonald Heating, AC and Plumbing, Inc. to contract your job:

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 McDonald Heating, AC and Plumbing, Inc. 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.
