Furnace Tune-Ups & Maintenance
The team at CM Heating TM knows how much you rely on your furnace through the Washington winter.
Furnace Inspection Checklist
Our furnace tune-ups are comprehensive. We’ll check all of the internal components and moving parts, as well as the electrical connections, to make sure your furnace is in tip-top condition. As part of our tune-up, we will do the following:
- Check flue system for safety & carbon monoxide leaks
- Check return & air filter
- Check all parts for visible wear & tear
- Check gas train and all electrical components/connections for safety
- Test thermostat operation
- Clean and check heat pump assembly if necessary
- Check proper burner ignition and efficiency
- Confirm complete system operation and safety
What You Can Do At Home
While you may not be able to perform a full heating tune-up at home, there are some things you can do. The first, and one of the most overlooked, things you can do is change your air filter regularly.
Many people leave their air filters for months longer than they should, and some don’t change their air filters at all. This will impact the health of your system over time and could lead to avoidable damage.
As particles and debris build up on the filter, airflow becomes restricted. After enough time, your air filter essentially becomes a wall in your HVAC system. This causes your furnace to work much harder, costing you more each month.
Eventually, your air filter can become blocked enough that it gets sucked into the system, where it will no longer filter air and could potentially damage your blower motor.
Another important maintenance step is preventing blocked vents. This involves a quick tour of your home to look at all of your air vents or registers, ensuring nothing is blocking your vents.
This could involve trimming or moving plants or repositioning furniture. Unrestricted airflow will keep your furnace working at peak efficiency and can even reduce your energy bills.

Heater tune-ups can be performed any time of year, but the best time is before the weather turns cold. You want to make sure no major issues are impacting your system before you are relying on it for home heating.
If your system breaks down during the winter, you’ll have to deal with a lot of running around, emergency expenses, and discomfort that could have been avoided with a simple furnace tune-up.

Sometimes regular maintenance just won’t cut it. If your furnace is older than 15 years, regular maintenance will begin to benefit you less and less. If your furnace is breaking down frequently, a replacement will be the most cost-effective solution.

Why You Need Annual Maintenance
Your furnace depends on regular maintenance, year to year. A furnace is like any other piece of equipment you rely on. Not unlike your car, regular maintenance keeps it running correctly and helps you stay ahead of potential issues that might be building up in the background. The big difference between your car and your furnace is that your furnace doesn’t have a check engine light that makes it obvious when something is wrong.
If something is wrong with your furnace, air quality can diminish and it can pose a health risk to you and your family. A furnace experiencing complications could break down, leak carbon monoxide, or potentially combust if the problem persists.
Assuming everything is okay, the main benefit will be maintaining your energy efficiency. Modern furnaces are high-efficiency, meaning they take less energy to run compared to older furnaces.
Most furnaces are 95% energy efficient. However, as a furnace ages, it naturally loses some of that efficiency due to wear and tear. Without regular maintenance, that efficiency drops much faster. This will cause your energy bills to grow over time.
