Our furnace stopped working and wasn’t blowing any air. Another company came over and diagnosed a faulty circuit board. The quote for repair was over $1000, and he suggested we should get a new furnace for over $2,500. We called Larsen for their free second opinion. The tech came over and checked the breakers and found an intermittent problem. Rather than blindly replace it, he verified the problem and got the furnace to start working again all as part of the free second opinion. I was so happy, I gladly paid him a service call fee to replace the breaker and get me going. Oh yes, my circuit board and furnace were just fine. Thanks Larsen for taking the time and using your expertise to fix me up.
