I called Paul Revere Revolutionary Service because my AC wasn't working on the entire second floor. Every year we kind of have a problem with that, but we can't really afford a new unit at this time. They came to work on it, cleaned all our screens and everything, but the master bedroom still wasn't working. They came back again without charge and tried to fix that. They thought it was fixed, but we went up there again and it turned out it wasn't, so i called them again this morning and they're going to try and get someone out here today to take another look, so I'm happy about that. I've used their for years, and I like them because they're very responsive to their customers and they try not to drive up the price.pricing seems.
