We are going on our third year using Mullins Mechanical Air Conditioning and Heating. We had been told by a company we had used for several years that we needed a new AC. Im so happy we called Mullins Mechanical for a second opinion. They serviced our units and said they were still good. This will be our third summer with the same units! Thank you Chris and Mullins Mechanical
