Who doesn’t love a simple solution? Here are some easy things you can do to resolve heating issues:
Check your thermostat settings
If your home’s temperature seems steady, but not as warm as you’d like, your thermostat settings may be the culprit. First, make sure your thermostat is set to AUTO not ON. An ON thermostat will blow air continually—but not warmed air.
Do this: Set your thermostat to AUTO.
Check your air filter
It’s easy to forget to change your air filter, but this simple action can make a big difference. When an air filter is dirty, air cannot easily pass through it, so your furnace has to work overtime to push out heated air.
If your furnace has to overcompensate, it might overheat. When a furnace overheats, safety sensors kick in and turn it off and then blow cold air to cool your furnace. If you notice cool air blowing and/or your furnace frequently turning off, a simple air filter replacement may do the trick.
Do this: Regularly replace your air filter.
Keep air vents open and free from blockages
When your air vents are closed or blocked by furniture or drapes, the furnace can overheat like it does with a clogged air filter.
Do this: Open all your vents and remove blockages.
Common issues we resolve
If you’ve tried basic troubleshooting but you’re still having problems, it’s a good idea to reach out to our expert technicians. We frequently resolve furnace issues that cause cold air like:
Pilot light/ignition issues
It’s quite common for a furnace pilot light to blow out and not be able to reignite. If your furnace can’t light up, then it can’t heat your home. We’re here to help keep your pilot light burning.
Your air ducts may have structural damage or holes which results in air leaks. Sometimes animals cause holes with their teeth or claws. Repairing and resealing ducts can make sure that your heated air isn’t escaping through leaky ductwork.
Inadequate gas supply
Furnaces operate with open flames, gas fuel and high temperatures. They’re designed to turn off if a safety hazard presents itself. If your gas supply has been turned off or is inadequate, your furnace may be shutting down for your protection. We can help you resolve your gas supply issue.
