Please- save your money and call another company!!
I called this company based on the reviews on this site. I have actually used them 3-4 times and, in retrospect, feel very silly that I didn't go to another company sooner. The service people are very friendly, return your calls quickly and tell you "what is wrong" with your system-- but BEWARE-- you will spend money and your AC/Heating (we had them come for both!) still won't work well. You will call them back and then there will be another "problem". I can only say that now, because after dropping $500, they told me my AC was fine. Obviously, it was not since it was HOT in the house. Anyway, the next day I called "Total Comfort"- they found a problem and FIXED it! We probably won't get our money back from Wolfe & Sons, but at least I can warn other people!!
