Nothing throws a wrench in winter like a broken heater. But before you pick up the phone, take a deep breath. Many common heating issues are easy to troubleshoot on your own. Before you pick up the phone, run through this checklist to see if you can get your system back up and running. If it is necessary to call a pro, Boston Unique Indoor Comfort is always here for fast, reliable repairs.
- Start with the Thermostat
Start with the basics by checking your thermostat settings. Is it set to “Cool” or “Off”? Is the temperature high enough to activate the system? If your thermostat runs on batteries, replace them to rule out low power as the culprit. It’s a quick fix that can save you time and stress.
- Check Your Circuit Breaker
A tripped breaker is one of the most common reasons for a broken heater. Go to your electrical panel and look for the switch controlling your heating system. If it’s flipped to “Off,” reset it. If it trips again, it could indicate a deeper electrical issue that needs attention.
*Do not attempt DIY electrical repairs. Always call a professional.
- Replace the Air Filter
Clogged air filters restrict airflow and can cause your system to overheat or shut down. If you haven’t replaced your filter in a while, now’s the time. Most filters need to be changed every 1-3 months, depending on usage and air quality. Professional heating system maintenance includes this step to ensure smooth operation, but it’s also easy to do yourself.
- Inspect Vents and Registers
Are certain rooms colder than others? Blocked or closed vents might be to blame. Walk through your home and ensure all vents are open and free from obstructions like furniture, rugs, or curtains. Proper airflow is necessary for even heating.
- Pilot Light or Ignition Troubles?
If you have a system with a pilot light, check if it’s still lit. If it’s out, follow your manufacturer’s guide to relight it. For systems with electronic ignitions, listen for clicking sounds when the heater tries to start. If you hear nothing or the ignition doesn’t fire, it may be time for professional heater repairs.
- Keep an Eye on the Ductwork
Damaged or blocked ducts can lead to uneven heating or cold spots. Check any visible ductwork for leaks, gaps, or debris. While you can seal minor leaks with duct tape temporarily, it’s best to schedule professional service to make sure your system can operate as it should.
- Investigate Any Strange Noises
Unusual sounds like banging, squealing, or rattling coming from your heating system can indicate loose components or mechanical problems. Tighten any visible screws or panels, but if the noise persists, your system probably needs professional attention.
- Seal Up Drafts
Drafty windows and doors can make your heating system work overtime. Use weather stripping, or caulk for a more permanent solution, to seal any gaps and keep the warm air in for the winter. Not only will this improve comfort, but it can also help lower your energy bills.
- Make Sure Your Furnace Switch is On
If you have a furnace, there is probably something that looks like a light switch nearby. It’s not unusual for that to be accidentally turned off – especially in homes with children. Check the switch and make sure it’s in the “On” position to restore power to your system.
- Confirm the Gas Supply
If you have a gas-powered heater, confirm the gas valve is open and your home is actually getting the gas it’s supposed to. If you suspect an issue with the supply or notice a gas smell, contact your provider immediately.
