Recent Review: Our a/c units were not properly installed originally, they were provided by the builder's vendor with a pre-installed, standard amount of coolant sufficient for a 15 foot distance between the condenser and the air handler. Because this was not enough, our motors pulled in oil and over time became damaged. We've limped along for 13 years, had replacement recommended 2 years ago. Finally, this July one of them broke. We called our warranty company and they were going to send out someone that Angie's List has an F grade and many other complaints on Google, but couldn't come for 2 days. I requested another service provider, no dice. So we called our regular service company, explained the dilemma and they came out the next morning to diagnose the issue. Priority Services has maintained our units for 9 years, so we trust them. After some discussion we decided to replace both units, no point in pouring more money into damaged units. My husband called around and received estimates that were $2500-3000 higher, so we're satisfied with our choice. Jason got the bad unit running on a temporary basis at no charge, including his call, the parts, etc. Because we have a maintenance agreement with Priority Services, they scheduled replacement the next morning, but early on that day they called to tell us their principal installer had had heat stroke and was hospitalized. They offered to send out a second crew, we elected to wait. Two days later, they were here. Polite, pleasant, not chatty, got down to business. I asked if I needed to arrange to have some of the sun rotted hose insulation repaired, the lead installer told me that was included. After the work was done I inspected and it looks like a tidy, professional job. The new units are 4 ton (same as old), 13 seer (more efficient than old 10 seer ones). I expect good service for at least the next 10 years.
