Why Furnace Failures Are Dangerous in Freezing Weather

Your furnace not working in PA winters can create a major problem for your home. Indoor temperatures can drop fairly quickly, especially during the overnight hours. Your pets, young children, and elderly household members are more at risk.

A lack of heat can be extremely damaging to your home as well. Your water pipes can freeze and end up bursting when you turn your water back on. This can lead to major water damage inside your home that will be costly to repair.

To make it even worse, having no heat in winter in PA can have homeowners searching for alternative options. Using items like propane heaters, grills, and even ovens are unsafe heating alternatives. They come with an increased risk of carbon monoxide poisoning and in-house fires.

Common Reasons Furnaces Fail in Cold PA Winters

Pennsylvania winters can put a heavy demand on your home heating system. Issues, like a dirty filter, can restrict airflow and make your system work harder. This can lead to issues like overheating and automatic system shutdowns if you don’t get routine maintenance. This can also contribute to worn-out parts that will fail during peak use.

Immediate Steps to Take When Your Furnace Stops Working

When freezing temperatures cause your furnace to not work, it’s important to act immediately. You never want to put off getting repairs, as it could lead to freezing temperatures inside your home. As a homeowner, there are certain things you can do to try to troubleshoot your unit. If you can’t get your unit started after going through these HVAC emergency tips, it’s best to call a professional.

Assess Your Thermostat

One of the first things you want to do when you have no heat in winter in PA is check your thermostat. Make sure that it’s set to heat, and the temperature is above what your current room temperature is. If the screen is blank, you may need to replace the batteries in your thermostat.

Check Your Air Filter

Another thing you can do is take a look at your air filter. If your air filter is clogged with debris, it can restrict airflow throughout your system. This can cause it to overheat past its limits, which will shut it off to prevent system damage. Try replacing the air filter and seeing if your furnace will start back up again.

Inspect Your Power Supply

If your thermostat screen is blank and you’ve tried replacing the batteries with no success, it may be the circuit breaker. It’s a good idea to head down to your panel box and check to see if the circuit breaker for your furnace is tripped. If so, be sure to turn it off and back on. If it immediately trips again, you need a professional for further assistance. It’s also a good idea to check the furnace itself to see if its disconnect switch has accidentally been turned off.
