5 Most Common Furnace Problems

You probably don’t give your furnace much thought – until it fails. The good news is that many furnace problems are easy to correct. While it’s advisable to hire a professional when your furnace isn’t working properly, there are some issues that you may even be able to fix yourself.

1. Clogged or Dirty Filters

Issue: Dirty or clogged air filters restrict airflow, causing your furnace to work harder than it needs to, making it less efficient.

Solution: Regularly check and replace filters every one to three months to keep your furnace in good working order and to ensure maximum efficiency.

2. Wear and Tear on Furnace Parts

Issue: Over time, components such as belts, bearings, and motors can wear out, leading to performance issues.
Solution: Schedule regular heating maintenance to catch problems early and avoid a headache later. This will help to replace any worn-out parts to avoid further damage.

3. Pilot or Ignition Control Issues

Issue: Problems with the ignition or pilot light can lead to issues with the furnace’s ability to start or stay running.
Solution: Check and clean the pilot assembly. Keep in mind that if you’re uncomfortable or unsure of how to do this, it’s always best to consult a professional HVAC technician.

4. Malfunctioning Thermostat

Issue: Incorrect thermostat settings, a dead battery, or a faulty thermostat can result in temperature control problems.
Solution: Verify thermostat settings, replace batteries if applicable, and consider recalibrating or replacing the thermostat if issues persist.

5. Lack of Maintenance

Issue: Neglecting regular maintenance and inspections can make your furnace prone to breakdowns and poor performance. You could also see increased energy costs as a result of failing to maintain your furnace.
Solution: Schedule annual maintenance. Annual checkups can prevent over 70% of all furnace repairs as well as improve your system’s efficiency by up to 16% — saving you money!

End of Summer Furnace Maintenance

Fall Furnace Maintenance
Replace your furnace filters! Dirty filters can cause premature system failure.

  • Replace your filters. Even if you do nothing else, change your filters. Regular filter changes keep HVAC systems running smoothly. Dirty filters cause the system to work harder, often resulting in premature failure.
  • Make sure your vents are clear. Obstructed supply vents can’t release warm air. Make sure all the vents in your home are unblocked by furniture, drapery, etc.
  • Check blowers and burners. Dust builds up on furnace burners during the summer. Before your furnace kicks on for the first time this season, remove dust and other debris to prevent a potential fire hazard. Also, make sure the burner is rust-free and properly aligned. Oil the blower motor to prevent unwanted noise and keep it running smoothly.
  • Schedule a furnace maintenance checkup. If you aren’t familiar with how your system works, we recommend scheduling a professional HVAC checkup. A technician will go over your furnace and your entire HVAC system to make sure everything is in good working order and make recommendations as needed. Checkups are an important part of maintaining your furnace because they allow professional to detect minor problems before they become major. Check out our maintenance program!

Signs Your Furnace Has a Gas Leak

What’s that nasty smell? If it reminds you of rotten eggs, it could be a gas leak originating from your furnace. While natural gas is odorless on its own, manufacturers are required by law to add a chemical known as mercaptan. This is what gives gas that unmistakable smell.

If you detect the odor of natural gas in your home, get out and call for help immediately. Gas leaks are extremely dangerous and could result in catastrophes like gas furnace explosions. The smell of gas isn’t always the only sign of a gas leak, though. If you notice any of these signs of gas leak, call for help right away.

Rotten Egg or Sulfur Smell

The chemical that is added to natural gas smells like sulfur or rotten egg. If you notice this uniquely unpleasant aroma, do not ignore it. Even if it isn’t being caused by a gas leak, you could still have a serious problem. Certain electrical issues cause this smell as well.

Hissing Sound

When a leak occurs behind a wall or in a pipe, you may hear it without being able to smell it. When it escapes from the gas line, natural gas makes a distinctive hissing sound. If you hear it, turn off your gas supply, if possible, and call for help.

Dead Patches in your Lawn

Gas lines run underground before entering your home and connecting to your furnace. If there is a spot on your lawn that is dying, you could have an underground gas leak. In addition, if a gas line runs underneath a pond or even a large puddle on your property, persistent bubbling could indicate a leak.

What to Do When You Have a Gas Leak

If you smell or hear a gas leak or if you have another reason to suspect you may have one, vacate the premises immediately. Don’t use anything that could cause a spark – including your cell phone. Wait until you are far away before calling anyone for assistance. If possible, turn off the main gas supply to your home. You may want to contact the fire department or your gas company for fast help in emergency situations. Contact a licensed service company that can respond quickly and repair the damage before disaster strikes.

  • Replace your filter. Furnace filters becoming clogged with dust, pet dander, hair and other debris over time. The more blocked the filter is, the harder your heating system has to work to heat your home. If it’s been a while since you last replaced your furnace filter, we recommend changing it before cranking up the heat for the first time this season.
  • Make sure your vents are unobstructed. If heavy drapes, furniture or miscellaneous clutter are blocking your wall or floor vents, airflow may be restricted. Make sure your vents are not blocked to ensure that your furnace can heat your home evenly.
  • Check your thermostat. Older thermostats don’t always work like they should. Sometimes, they fail to correctly read the temperature or keep your furnace running as efficiently as it should. Test yours, and if you find that it is no longer working correctly, consider upgrading to an energy efficient programmable thermostat.
  • Schedule a furnace tune-up. Prevent winter breakdowns with a tune-up. When you have your furnace tuned up by Larry & Sons, your technician will thoroughly examine the system take preventative measures to make sure it is good health.

Winter is an expensive time of year for most homeowners. By tackling some basic heating maintenance, though, you may be able to avoid a costly mid-winter heating repair.
