We called Ashton because our house's central air conditioning unit had stopped working. After performing several high-pressure tests, Wes was able to confirm the locations of the leak. As the condensing unit was quite old (10 years) and used a soon-to-be-obsolete refrigerant, he recommended that we replaced it. His colleagues, Ron and Mike, visited several days later to discuss their recommendations. The evaporator unit and HRV had been installed in the attic. It was difficult accessing to them because of the ductwork (pipes) and support beams. Mike came up with the great idea of installing a catwalk, instead of another access door. Ron gave an honest assessment of the problem and explained to us our options. We ended up installing a new condensing unit with a new ozone friendly R410A refrigerant. We were very impressed with their professionalism, attitude and work ethic. All in all, we were very pleased that we had called Ashton.
