Importance of Scheduling Preventative Maintenance

While preventative furnace maintenance may just seem like a hassle or another chore to add to your list, it plays a vital role in the health and longevity of your system. Routine maintenance can help spot any potential issues early on while they are still minor, therefore preventing them from developing into more catastrophic breaks or failures.

It is recommended to perform preventative maintenance on your furnace at least once a year, preferably during the fall. Since your furnace sat idle during the summer, getting a check-up before the winter can help to make sure that your furnace is in good working order before temperatures begin to drop.

Our Professional Furnace Tune-Up Process

If you have already scheduled your tune-up appointment, you want to know what you are getting yourself into. What exactly goes into a furnace tune-up, and how complicated is the process? Our furnace tune-up process at Randazzo consists of the following 8 steps.

1. Remove the Furnace Door

First and foremost, your technician will remove the door on your furnace to access the internal mechanics. The door is typically a metal panel that is either attached by a few screws or just pops onto your furnace. Your technician will safely remove this furnace door to take a look at the inside of your unit.

2. Change the Dirty Air Filter

Every style of furnace has an air filter that catches debris from the air before it can get into the rest of the mechanisms. Your technician will take a look at the filter and replace it if there is a buildup of dust in it. For individuals who struggle with asthma or allergies, these filters should be changed every six weeks.

3. Inspect the Flames and Gas Burners

The burner of your furnace has little flames in it that work to create the heat that is sent throughout your home. These flames should be blue. If they are a different color such as orange, this can mean that there is a buildup of dirt in the burner. Our professionals offer reputable furnace tune-up services in Detroit, Michigan and will inspect your gas burners to diagnose issues.

Your technician will check these flames and make sure everything looks good.

4. Vacuum the Furnace

Dirt and other debris can naturally build up in your furnace over time. If too much builds up, it can lead to performance issues with your furnace. Your technician will take a vacuum hose and gently clean out any dirt, debris, or dust inside the furnace.

5. Check and Clean the Condensate Lines

The condensate lines in your furnace are a series of tubes that collect condensation from your system and drain it to prevent buildup. Your technician will inspect these lines for any cracks or potential leaks and then clean them out to make sure they do not develop any clogs.

6. Gas Combustion Inspection

Your technician will then check the gas valves on your furnace for any issues and check for any potential gas leaks, which can be serious if not addressed properly.

7. Thermostat Configuration

The thermostat on your furnace helps keep track of and maintain the temperature inside of the furnace to prevent overheating. Your HVAC technician will check to make sure that your thermostat is working properly and reading the correct temperature.

8. Airflow Assessment

Lastly, our team of technicians will do an airflow assessment to make sure that there is proper ventilation and airflow inside the furnace.

Perks of Routine Furnace Tune-Ups

Staying on top of routine furnace tune-ups can do wonders for your furnace as well as your finances. Many manufacturer warranties have a requirement that maintenance is done on the unit a certain number of times each year. This means that there is the potential for your warranty to become void if you do not keep up with furnace tune-up and maintenance appointments.

In addition to maintaining your warranty, keeping up with furnace tune-ups can save you money on more serious repairs later on. You will also save money on your energy bills with a more energy-efficient and eco-friendly unit. Yearly check-ups can also protect your home from serious catastrophes such as leaks, fires, and carbon monoxide leaks.

This has many benefits, including:

  • Saves money: Optimizing system performance reduces utility bills and long-term HVAC repair or replacement costs.
  • Eco-friendly: A “well-oiled machine” utilizes less energy, resulting in a lower carbon footprint, cleaner skies, healthier waterways, and more.
  • Protects your home: An adequately serviced machine is less likely to ignite a fire, leak, cause carbon monoxide poisoning, etc.

How Long Will Furnace Maintenance Take?

On average, a furnace maintenance appointment should take no longer than 1-2 hours. This may sound like a long time, but this ensures that your technician does a thorough job and all potential issues are addressed accordingly. It is better for your technician to take their time than to rush through the tune-up.

However, there are a handful of factors that can impact the timeline of your appointment. These can include the current state of your furnace as well as the extent of the work that needs to be done on your unit.

Frequently Asked Questions

We recommend scheduling furnace maintenance for the late summer or early fall. This helps ensure optimal performance during the fall and winter months. You can also schedule a post-season appointment for the spring.

Aside from cleaning and visual inspection, it is always best to leave maintenance to a licensed and insured professional. This ensures the work is done properly and helps preserve manufacturer warranty coverage.

You are not alone if you fall behind on heating maintenance. While you can’t necessarily “catch up,” you can protect your furnace system from further damage and address any issues that have developed since your last maintenance service.
