Having moved to Memphis from Michigan, we were puzzled by the crawl space mechanicals and plumbing and the 5 ton heating and air conditioning units. We knew we had plumbing issues and discovered some detached ducting. After a bad experience with a corporation masquerading as a local outfit, we called Coate's. They sent out a rep who explained their work and gave us reasonable estimates. When the ducting specialist and plumber came out, they could not have been more professional. They explained everything and fixed all of the problems. It cost me 1100 dollars for the work, but I did not mind because they thoroughly explained what was needed and kept me in the loop all of the time. We signed up for their maintenance program based on this experience. They are a really solid, locally owned and operated company.
