A furnace inspection will turn up any issues that could interfere with your safety, heating costs and your system's reliability. Additionally, a licensed HVAC professional knows how to inspect and maintain your equipment to bring it back to factory settings as much as possible.
During routine furnace maintenance, a qualified technician will typically:
- Clean the inside of the blower and replace the air filter if necessary.
- Lubricate the fan motor and inducer motor if present.
- Tighten the electrical components, if necessary.
- Evaluate the condition of the burner and the heat exchanger, looking for problems with either.
- Look at the flue draft and make sure that it's clear and no leaks exist.
- Evaluate the quality of the flame with a combustion analyzer and make adjustments to the gas-to-air ratio if necessary.
- Verify that the high limit switch and other safety controls are functioning as they should. The thermocouple is an important safety element during a furnace inspection since it turns the gas supply off if the pilot goes out.
- Inspect the ductwork for leaks or other obstructions. If needed, he will quote needed work to seal leaks with mastic or metal tape. The technician should never use duct tape, since its adhesive is short-lived.
- Check the gas connections and make sure they're properly tightened.
- Check the thermostat for proper operation.
The safety aspects of a furnace inspection are crucial when operating combustion heating equipment, while keeping all the parts clean avoids problems. A furnace that runs during our long heating season needs to be as clean as possible, to both lower energy consumption and increase safety.
When dirt collects inside the blower, it can cover the heat exchanger that acts as insulation. Not only does it retain heat longer, the excessive heat can weaken the metal. Cracks can form that may emit carbon monoxide (CO) into your home. Should the technician find this problem, he or she is obligated to shut the gas supply off until you've repaired it or replaced the furnace. There is an extra cost to conduct this additional service, but helps to protect the investment or verify the performance of these important units.
During a furnace inspection, it makes sense to ask the technician to also check any accessories attached to the furnace such as a humidifier, electronic air cleaner, UV light and even the hot water heater that is often nearby.
