What to Know about Preventative Maintenance for Your Furnace

In order to maintain a healthy body, it’s recommended that you get an annual physical exam and that you eat a balanced diet and exercise. The same care should be given to your furnace to ensure that it continues to function as expected for many years. It’s important to check out your furnace on a regular basis and make any necessary fixes immediately so that the rest of the system can perform optimally. Here are a few things to understand about furnace maintenance in Minneapolis.

    • Changing the filter every 30-90 days (depending on the manufacturer recommendations for your furnace and for the type of filter used) will keep dust, allergens, and other pollutants from clogging up your system. It also ensures that the air quality in your home stays clean and breathable.
    • Annual duct and vent cleaning can help keep your air flowing freely and clearly throughout your home. Over time, static can cause dirt, dust, and hair to stick together. Also, if you have pets or kids, toys, crayons, food, or other small items can slip down into a vent.
    • Check to make sure nothing is covering a vent. Sometimes furniture, a pile of clothes, or other things can block an entire vent, causing that room to not get the air flow it needs and making the furnace work even harder. In order for a furnace to work efficiently, you should have around 90% of the vents in your home open. Closing too many will cause undue pressure on your system.
  • If your ductwork is exposed (as in the basement or attic), check the connection parts often to make sure there are no air leaks. If you do find any cracks, gaps, or loose fittings, it’s recommended to call a professional to get them fixed as soon as possible.
  • Many thermostats have hard wiring and batteries that keep them working. If your thermostat seems to be having some issues or you see that it has gone dead altogether, replacing the batteries could be a simple maintenance solution.
  • Have a certified HVAC technician service your system once a year to assess efficiency, spot trouble areas early, and to lubricate moving parts so they can work effectively. By catching problems before they happen, you can save a lot of money and frustration. Also, by repairing or replacing parts during the off-season, you can avoid having to wait long periods of time for an available service person when the outside temperatures may be extreme.
