Why should you bother getting your heating appliance repaired if you currently have heat coming out of the unit? Or, what if you know your heater may need a little fine tuning but so far is doing OK? What if it's summer time, and you want to ignore any potential heating issues until the weather starts to get cold?
The reality is your heater may need to be repaired even if you are currently receiving hot air or you aren't planning on using your unit for a few more months yet. If your heater may need servicing in the near future, that's already a sign you need to get your HVAC specialist on the phone. Do you need heating services if your hot air is already running? Here are signs you do.
Your heater works but not consistently
So, your heater blows hot air, but sometimes the unit turns on and other times it doesn't. Or, it turns on and off randomly and you have no idea why. If your heater is blowing hot air but isn't doing so reliably, you have a real issue on your hands that needs attention. Don't ignore your potential heating problems or just get used to what's going on. Instead, see what you can do now to have your heater inspected before it decides to fail on you completely.
Your heater smells funny
If your heater emits a strange odor when it's on, like the smell of hot rubber, burning plastic, or a weird, gassy smell, turn the unit off right away. Even if you don't see fire or smell smoke, you might have a real issue on your hands that needs attention immediately. You may have a motor that is going out, a fan that is chipped and failing, a belt or oil issue, or even a hidden fire that you can't outright see. Even if your heater is running, if it smells weird, turn the unit off and call for emergency HVAC repairs.
Your heater is older
How old is your heater? An older heater may have underlying issues, even if it appears to be working just fine. Have your HVAC specialist inspect your heater to see if it needs a new fan, needs the filters cleaned out or replaced, or has other issues that need attention. This way, you can stay on top of your heater's overall operation and catch smaller issues in your older unit before they become quite expensive to fix.
