One of the best ways to prevent a furnace from failing in the cold winter months is to schedule an annual inspection from a certified heating contractor. By reducing the risk of a breakdown, homeowners can save themselves from freezing nights and costly furnace repairs. According to Muotka Mechanical—a leading furnace service and repair company in Anchorage, AK—routine inspections can also keep your heating system operating safely and efficiently.

So what does a furnace inspection entail? While the checklist may vary from company to company, this Anchorage heating contractor is happy to pinpoint the most common steps.

5 Aspects of a Furnace Inspection

1. Look for Visual Signs of Wear and Tear

To start, your heating contractor will look for signs of wear and tear that could impact your furnace’s performance, such as ensuring the blower access door has a tight seal and the belts are intact. It’s also crucial to inspect the electrical system and look for signs of corrosion.

2. Calibrate the Thermostat

Your furnace may need to be calibrated to produce a degree of heat that matches the temperature to which you set your home thermostat. A trustworthy furnace specialist will carry out tests and adjustments to align the two systems.

3. Check Safety

Many furnace components can pose a threat to your safety, especially if the system is operated by gas or oil. For the latter, heating contractors will look for sources of carbon monoxide production, such as a cracked heat exchanger. They will also check the pilot light, and clear flues and vents to maintain your indoor air quality. If the furnace is electric, a heating contractor will want to inspect the wiring and rule out the risk of an electrical fire.

4. Clean Components

In addition to replacing a dirty air filter, your contractor may provide a routine cleaning service to restore your system to its best condition. Usually, this involves removing dirt and debris from the blower wheel and vents.   

5. Lubricate Moving Parts

The heating specialist should reapply lubrication on moving parts to prevent the motor from becoming overworked. This step is crucial to maintaining the product’s life, as well as your system’s energy-efficiency.
