Customer has a 3 year old American Standard gas furnace, she said that her furnace and thermostat were fried and not working. She had an electrician come by and inspect it, but he wasn't able to do anything. Upon investigation, I found that the thermostat has failed due to a power surge that hit the home. I also found that the fuse on the control board was blown and the contactor at the condenser was fried along with wiring. I replaced thermostat, contactor, and fuse/wiring and tested all modes of operation. All components are within manufacturers specifications and system fully operational. Recommend annual maintenance and power surge protector for either home or equipment.
An undersized heating system will, obviously, struggle to heat your home effectively. What some homeowners fail to realize is that an oversized system is no better. If your system is too big for your home, it will short–cycle which can lead to increased wear and tear or damage to your system.

High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace is the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
