My wife and I have been very nervous about our older furnace for a few years now. It is a little noisy and makes a loud puff noise when starting up. Now that fall is coming so soon we had to get it cleaned and serviced. CARL'S FURNACE was highly recommended by 3 friends. We took the plunge ang telephoned Carl. The very best decision. Carl's crew did a bang-up job. Quick, and definitely thorough. Reasonable price, but not too cheap. Thank you, Carl, great srvice. Robert F. Prince George
