Called 3 months ago for furnace cleaning and electrical work. The guy said we can t schedule now but we ll get the work done in a couple weeks. A month later I called back and they said the same thing. I never heard from them. Why do you string people along like this? We were long standing customers for many years. Obviously we have finally learned that their word means nothing and have taken our business elsewhere.
