The HVAC professionals at MRS Heating and Cooling recommend scheduling a furnace checkup as we head into cooler weather. Having your furnace professionally cleaned and serviced now is a good way to keep it working efficiently all winter long and help you save on energy costs.

What can you expect our technicians to do at a furnace checkup?

1. Clean the flame sensor.

Why take chances with your most major appliance with an open flame? The flame sensor is a stainless rod encased in porcelain. It allows your unit to react to unsafe conditions in a fraction of a second. Keeping this sensor clean will help your furnace operate safely. This is one of the first things we do on an appointment to clean your furnace.

2. Check the resistance level of the ignitor.

If the resistance level is not within factory specifications, we suggest replacing it. Your furnace will not work if the ignitor malfunctions, and replacing this part is far less expensive than a new furnace. By checking this during our annual visit to service your furnace, you can save money in the long run.

3. Clear drain system of debris.

Most high-efficiency furnaces have condensate drains. When these drains are blocked, the furnace will shut down. We’ll check this drain and clear it out so it’s ready to work for the winter.

4. Share furnace filter recommendations.

If you are part of our MRS Club at the Platinum level, we’ll change your filter for you at no additional charge. Not part of the Club yet? No problem. We can sign you up OR set you up with a filter at a minimal charge.

5. Check the temperature rise in the operating heating mode.

This will help lengthen the life expectancy of your heat exchanger. The heat exchanger is a device that allows heat to transfer between two or more fluids/gasses. The heat exchanger working properly will help your furnace keep doing its job.

6. Visual inspection of electrical components and flue venting system.

We’ll make sure that all parts are where they need to be for your furnace to safely operate.

While we’re at your home for your furnace checkup, we can also perform an air quality assessment and share recommendations. This is especially important for homes with pets, people with allergies, and individuals prone to illness.
