Tips for DIY Furnace Maintenance

With regular care, you’ll experience less downtime. Here are some tips to help you maintain your furnace.

Clean or Replace Your Filter

Your furnace filter is usually installed where the return duct enters your furnace. It serves a crucial job by removing all kinds of particulates from the air before it moves into the furnace equipment and is heated. Particulates may include dust, dust mites, pollen, pet dander, bacteria, spores, and more. After the filter has been in place for a while, it gets full of debris. A dirty filter results in inadequate airflow and the furnace won’t operate as efficiently as it was designed because it has to work harder to pull air through the densely packed filter.

How often you need to change your filter may depend on things such as how often you clean and whether or not you have pets. A good rule of thumb is to check the filter monthly for debris. If you can see hair and dust on the surface, then replace the filter or wash it if it’s a reusable kind.

Ensure All Vents Are Open and Unblocked

In order for your furnace to work efficiently, the air in your house must be able to circulate completely throughout your home. Make sure your registers are not blocked by furniture, boxes, or other household items and ensure dust is not trapped in the cover.

Keep the Area Around the Furnace Clear

Most furnaces are usually located in the basement, a crawl space, or a storage room. However, your furnace isn’t designed to operate with extra belongings around it. This is a safety issue because there is burning gas in the furnace, but it also helps the furnace run smoother because air can circulate freely. It’s important to keep a three- to five-foot area around your furnace completely clear of stored items. Anything flammable (clothes, paint, aerosols, gasoline, boxes, etc.) should not be placed in the general vicinity of your furnace or water heater.

Ensure Your Gas Furnace’s Exhaust Flue is Clear

Carbon monoxide, nitrogen dioxide, and sulfur dioxide can all be found in the fumes from your furnace, that’s why the exhaust flue needs regular attention. If it is blocked and isn’t allowing air to freely move from inside the system to the outside of your home, it can cause dangerous problems. If you suspect a problem, contact us immediately to have it checked out.

Combustion gasses can cause very serious health effects including:

  • Headaches
  • Dizziness
  • Nausea
  • Fatigue
  • Heart palpitations
  • Collapse
  • Unconsciousness
  • Death

The installation team arrived on time and went right to work.They worked with confidence and professionalism.We appreciated the care in protecting our floors and even the choice of how they went up on the roof indicated that they really did care. This company did what they said they would and certainly has our vote of appreciation and gratitude. We will happily recommend Design Aire to anyone.

Ken L.

One of the best companies to work with. My own profession is in a service industry and so I very much appreciate all the positive things about Design Aire.
The install crew arrived right on time and took exactly how much time they said they would to complete the job. The work was done well, the crew cleaned up after themselves, and were very pleasant. Seth in the office was extremely in-tune to our needs and very responsive.
I would highly recommend Design Aire.

Heather H.

Our new HVAC system was installed yesterday and we could not be happier. From quote to completion the process was great! 100% would recommend!

We have used Design Aire for both a new furnace two years ago and a new AC unit this summer. Everything was done very professionally and quickly. I would not hesitate to recommend them to anyone needing any type of HVAC work done.

Sean K.

Design Aire was the best choice from start to finish. Design Aire gave me the best price with the most detailed quote. The service technicians were very friendly and completed the job ahead of time. I highly recommend Design Aire.

John K.

We've used them for our old house and our new house. They are honest, friendly, professional and affordable. We felt lucky to find them.

Maddy R.

I was very impressed with Design Aire. They were timely and did an outstanding job with the installation of my new furnace. They had great communication and went above and beyond. I would highly recommend them to friends and family. Thank you so much Seth and Design Aire for making this an effortless transaction. VERY PLEASED!

Jonny M.

Design Aire sent a salesman to plan the system, and just a couple of days later sent the installers to remove the old system and install the new one. Everything happened when they said it would and the system performs as they said it would. All of the Design Aire staff were courteous, the work was performed efficiently and neatly, and they left the area cleaner than they found it. This is the second unit Design Aire has installed for us, and I have no need to look elsewhere.
