Annual Warm-Air Furnace Maintenance

One of the best ways to ensure your furnace will provide years of safe and clean warmth is to have it checked every year. Regardless of the age, you can actually improve on energy efficiency when the furnace is operating at peak performance. As you will see from the information below, the process is simple and affordable but unless you are an expert, you should have a professional do the work. Although the price will vary, you can expect to pay between $100 and $150. Regardless of the person doing the work, the most important aspect is to ensure no carbon monoxide leaks into the home. This invisible and odorless gas kills people across the country every year.

  • System Shutdown: The electrical power and fuel supply will be turned off first. Then, depending on the type of furnace filter, it will be replaced or cleaned. If the filter goes unchecked, dirt and dust will filter into the blower and coil assembly, causing the level of efficiency to be dramatically reduced and the motor potentially damaged.
  • Combustion Chamber: Next, the combustion chamber will be cleaned. What happens is that overtime, substances such as soot, water, vapor, and carbon dioxide can build up. When this occurs, erosion can occur. The professional will use a wire brush to scrape the carbon buildup out and then vacuum the interior.
  • Flue Pipe: This pipe is the one that can leak, causing deadly carbon monoxide to enter the home. The pipe will be checked carefully for holes. If any are found, they will be patched using foil tape. However, if it is found that the level of damage is significant, then the entire flue will be replaced.
  • Oil Filters: Some systems have oil filters, which would need to be removed and replaced.
  • Burner: Next, the burner would be adjusted to test for efficiency. Using a combustion analyzer to help determine the efficiency of your furnace, the burner will be checked. This works by measuring the level of gas in the flue, which is done by the air gates being adjusted properly.
  • Floor Vents: These too should be cleaned. Many times, pet hair, dust, scraps of food, and even small toys can fall into the vents. These block the air, which means to heat the home you have to turn the thermostat up. With these changes, you and your family will enjoy a warm home while lowering the cost of heat.
