I experienced some problems with my furnace on a Sunday evening. I called Garrison & Garrison the following Monday morning to schedule a service call. A technician came out Monday afternoon and examined the unit. After examining the unit he concluded that I needed a new furnace/air unit and recommended some alternatives ranging from $3500 to $3900. I paid the $44 service call and slept on it. The next day, I contacted another contractor for a second opinion. The second contractor examined the unit in more detail and found a bad electrical connection. I paid a $55 service call and ended up with a working furnace. You be the judge.
