The Cold Snap That Breaks the Furnace

December 13, 2018 Published by Leave your thoughts

Winter is here in full force, meaning you can expect your furnace to be working hard to keep your home cozy and warm. Of course, when the mercury dips lower and lower, the amount of stress your furnace experiences to keep your home at your desired temperature increases.

Therefore, it’s important to know the ways in which extreme cold weather can affect your furnace and how you can keep these types of furnace problems from becoming such a severe issue that you end up having to spring for some extremely costly furnace repairs in Lexington, KY. Keep in mind that while Kentucky may technically be in the South, it still has the potential to get very cold here—Lexington recorded temperatures as low as minus three degrees Fahrenheit in January 2018, and there’s no reason to believe that can’t and won’t happen again this winter.

Know how the cold affects your furnace

The colder the weather gets outside, the harder your furnace has to work to keep your home warm. While high-quality insulation can help you prevent your furnace from overworking, there’s only so much strong insulation can do when you’re dealing with zero-degree temperatures.

Here are a couple examples of some of the most common issues people experience with their furnaces during the winter months:

  • Short cycling: This occurs when your furnace frequently shuts itself off and turns itself back on within relatively short periods of time. The biggest problems that tend to lead to heat cycling are clogs in the filters and blowers, which restrict airflow. This is why it’s important to change your filters and check your blowers regularly. However, if your filters and blowers are clean, then the problem likely lies with a faulty thermostat. Your manufacturer’s instructions for the thermostat or furnace may have some insight into how you can troubleshoot the problem, but if that doesn’t work or if you’re uncomfortable with trying to resolve the issue yourself, it’s important that you get an HVAC technician out to your property as soon as possible to get the work done.
  • Sudden furnace shutdowns: It can be scary if your furnace suddenly stops working, especially if you’re in the middle of a major cold snap. Before you call a service technician out to your property, though, there are some steps you can take. Check your fuse box or circuit breaker to make sure you didn’t suffer a power surge that resulted in a blown fuse or tripped breaker. You can also check to see if the pilot light is still burning in the furnace. If these issues don’t appear to be the root of the problem, then you can call for HVAC assistance.
