When your furnace goes out in the middle of winter, you’re dealing with more than a cold house because pipes can freeze up inside your walls and burst, which floods your entire place and leaves you staring down thousands of dollars in water damage repairs.
This guide helps you to understand why furnace breakdowns happen most often in winter, what different repairs will cost you, what you can fix on your own, and when you really need to bring in a licensed HVAC technician.
Common Furnace Problems That Need Repair
Failure of heating systems does not follow trends that occur annually. This is a good idea as it not only helps you get the situation right when you call the service provider, but also gives you a clearer estimate for repair costs.
When the Furnace Won’t Start Up No Matter What You Try
When you adjust the thermostat upward to a higher temperature, absolutely nothing happens. There are no clicking sounds coming from the basement, no fan noise anywhere in the house, and complete silence, like the furnace isn’t even trying.
Homeowners report this frustrating problem more than any other issue, particularly right after the heating system has been sitting idle and turned off through all the warm summer months. Repairing this issue can cost anywhere from $100 for a simple battery replacement to around $500 if a professional needs to install a new ignitor.
When Your Furnace Blows Cold Air
You can hear the fan running and all the normal sounds coming from your furnace, but only cold air is coming out of the vents. It’s really frustrating because the furnace seems like it’s working, yet your house won’t warm up.
A clogged filter might be blocking the airflow, while the blower motor could also be acting up. Your furnace may still be generating heat, but if the blower isn’t doing its job, that warm air just sits inside the unit. All the heat stays trapped in there instead of moving through your house.
DIY Troubleshooting Checklist Before Calling a Service Person
Homeowners themselves can easily fix some heating issues without paying anyone to visit and service the system. Follow these simple steps one by one before spending money on a service call that might not be necessary:
- Put in fresh batteries if the thermostat display appears dim or completely blank.
- Check your home’s electrical panel for any tripped breakers that serve the furnace.
- Remove your furnace filter and put in a new one if it’s full of dust and looks grey or brown.
Simple Maintenance That Prevents Expensive Repairs
Staying on top of routine maintenance really does cut down on what you’ll spend fixing your furnace later. Most of this stuff is simple enough that anyone can do it, and no special skills are required. People who stick to a maintenance routine get a few extra years out of their furnaces before needing a replacement.
Small investments of time throughout the year prevent those massive repair bills that always seem to hit at the worst possible moment when you can’t afford them. Swap out air filters every 1 to 3 months while you’re using your heating system during winter.
What Furnace Repairs Cost
The majority of service technicians have common ignitors in their work trucks so that they can complete such repairs the same day, rather than making you wait until parts are received in the mail. When it comes to simple and standard models that do not cost much, the replacement cost of a simple thermostat is $100-$300.
Gas furnace ignitors tend to cost between $150 and $400 dollars with the man-hours. A new blower motor will typically run you anywhere from $400 to $800, depending on what kind of furnace you have.
When You Need to Call a Pro
Some furnace problems are flat-out dangerous and shouldn’t be DIY projects. Natural gas leaks, high-voltage electrical work, and carbon monoxide issues all require someone who knows what they’re doing. Trying to save money on a service call just isn’t worth putting your family at risk.
Frequently Asked Questions (FAQs)
How long does a furnace last?
Furnace lasts between 15-20 years if you follow proper maintenance routine.
What causes that banging noise when my furnace starts up?
That loud bang usually means dirty burners. Gas builds up for a second before igniting all at once, creating that explosion sound.
Should I repair or replace my old furnace?
If your furnace is under 10 years old and the repair costs less than half a new unit, fix it. But if your furnace is running for more than 15 years, replacement is a better option.
