We have used this company before for service for our Lennox pulse furnace. This year, before even looking at the furnace the serviceman said he was going to “pressure test” it, he did this and said it had failed and was condemned. It was observed that there was no check made to see if the plugs inserted into the holes were leaking or not. We were charged $165 for that pleasure. He told us that he would get the salesperson to call who did so extremely quickly and then quoted us $6500 for a new furnace. Needless to say, we got other quotes and are very happy with our new furnace that was considerably less.
