Another contractor abandoned me after repeated attempts to repair a two-year old air-conditioner unit still under warranty. Dal Star showed up about two hours after I called on a Saturday afternoon. Mike checked out the non-working system and confirmed pretty much what I already knew; repeated attempts by the previous contractor to repair system coils made another repair attempt«iffy» at best. Mike checked on the warranty for me and confirmed that the compressor was still under warranty. He offered to replace the compressor, attempt another coil repair and replace the expensive«older-type» refrigerant. Or he had options available for a new system, with a new warranty using the newer(and cheaper) coolant. It was an easy decision. Since I had already been through three repair attempts on the system that didn’t work, and there were no guarantees, I was ready to move on. After he quoted me a price of $ 3,098 for a new 5 ton split system, I elected to have Dal Star install a new Goodman system at the quoted price. Mike told me he had«name» brand equipment(more expensive) for sale also, but the Goodman system was made by one of the name brands and was much cheaper.(My internet research confirmed what he told me about Goodman; I found very good reviews.) The complete job took about three hours, including the installation of a new thermostat. It works great. I sure is nice to have a new system in place … that works! Two-thumbs up to Mike and Dal-Star Services! Two additional comments. First, Dal-Star is a smaller operation. That could be good and bad. You know the owner, his prices are very competitive, no high pressure; and he does good work. I could imagine that at certain times, his cup might runneth over. But that’s just conjecture, he was lightning fast with my service call. Second, I’ve dealt with one of the bigger boys in the industry before, and it was like dealing with an unscrupulous used car salesman. If you’ve dealt with one of those you know what I mean! Mike offered options and I picked what worked for me. There are a lot of fine businesses with good reviews. Dal Star Services receives a 5 Star review from me … and for good reason. Thanks Mike!
