Merit added central air conditioning to my existing furnace. Shane and Jeramie did a great job. After getting the bid they started work quickly. The install was started soon thereafter and finished quickly. They were professional and went beyond what I expected.

Merit installed our home furnace and air conditioning. They did a fast, complete, and knowlegeable estimate and install. Called with questions and they always answered and took care of any concerns. We will use them again.

We needed our furnace serviced and the technician was on time and friendly. He explained the process they had completed and gave a few recommendations for parts that may need replacing in the future and ordered them so they are in stock if we need them. I will use them again!
