Please check the following before calling us for service. These are problems that homeowners tend to overlook and are not covered by warranty.
Step 1: Is your thermostat set to the correct function?
Step 2: Has the power to the furnace been shut off?
- Electrical panel breaker
- Power switch located close to furnace of high in the basement stairwell
- Ensure the furnace fan door is on properly
Step 3: Is the filter clean? A dirty filter will eventually cause service problems and drastically decrease efficiency of both the furnace and air conditioner.
Step 4: High-efficiency furnaces have a System 636 PVC vent pipe which terminates on the side of home or through the roof. Ensure this is not blocked by debris, snow or ice.
If you cannot locate the problem by following these steps and require service, take note of the furnace model and serial number and call us.
