Now is the perfect time to start thinking about scheduling furnace maintenance before the mad rush this fall. With colder weather looming in Haverhill, you will soon be relying on your furnace for indoor comfort. But turning on your furnace for the first time after months of inactivity could bring up some issues with your system that need to be addressed before the first cold front sweeps through Haverhill. The sooner you test your furnace, the better.

If you switch your furnace on and find that it isn’t operating as you are used to, here are a few troubleshooting tips our experts at Andrew DiPietro’s Climate Zone recommend before you call us in for a tune-up:

  1. Double check your thermostat.
    This is one of the easiest and most overlooked steps when having tricky furnace issues. First and foremost, make sure that your thermostat is set to HEAT and not COOL, and then check that the temperature setting is higher than the current indoor temperature. You might even consider turning your thermostat up a few degrees to test the heat and airflow. Changing your thermostat’s batteries might also be a good call during the change in seasons, especially if you can’t remember the last time you swapped out its batteries.
  2. Open up your air vents.
    Closing air vents (supply registers) in rooms that aren’t normally used in your home can be simple way to save some money on your energy bills. However, be very careful about how many vents you close. Shutting off too many vents can increase the pressure in your furnace, causing potential mechanical issues and making it work harder to heat your home, decreasing its lifespan.
  3. Inspect your air filters.
    Most people forget about their air filters—we get it. But their importance for the efficiency, health and cleanliness of your home cannot be overstated. If your air filters are dirty or old, they could restrict airflow in your home, reduce your home’s overall energy efficiency, increase your energy bills and even cause your furnace to stop running without warning. Our Climate Zone experts have an easy system to check if your air filters need replacement: hold your air filter up to the light—if you can’t see light coming through it, it should be replaced and it’s probably a sign that you need routine furnace service, as well. Check the size on the air filter and, if it’s a disposable filter, simply replace it with a same-sized new one that you can get at any home improvement or department store. Want an added tip? We recommend writing the date that you installed your new filter on it somewhere so you can know how old it is next time you check your filters. The air filter’s packaging should indicate how long it usually lasts.

These troubleshooting steps should get you on your feet and fix any small issues that could be causing your furnace to act up.
