5 Heating System Issues in the Winter and How to Avoid Them


As winter grips your city, it’s probably safe to assume that you’ll be spending a lot more time in your home. Keeping your home as cozy and comfortable as possible is essential for health. Spending too much time in the cold can lead to life-threatening health problems, but if you keep your heating system up to date, this shouldn’t be an issue.

So relax, close the door, and keep reading for the most common winter heating problems and how to prevent them.

1. Busted Heating System

The most common problem with heating systems can be summed up in one word: broken. Broken heating systems need to be fixed immediately. This can be quite the task, so if you’re unsure how to handle it, it’s best to leave it to the professionals.

It’s important to realize that your heating system might not always be broken. Something is wrong if you can’t get a fire started in the fireplace or your home remains colder than usual when it’s cold outside.

2. Frozen Pipes

When it’s cold outside, water in your pipes can freeze, which is a problem. The water that’s frozen in your pipes can’t move and deliver heat to your home. Since it’s frozen, it needs to be removed.

Sometimes, a cold feeling in your home is more vivid than the temperature reading. This is how cold pipes feel. But how do you know if there’s a problem with your pipes?

3. Uneven Air Flow and Falling Temperatures

If your home feels drafty and your furnace struggles to maintain even temperature throughout the room, the problem may be in the ducts. The heating system may not be able to move the cold air in the room properly, which can create a lot of problems.

The cold air stays on the lower floors, and the warm air stays on the upper floors. Try to spot leaks in the ducts and call a heating repair professional if you find any.

4. Dirty and Clogged Filters

It’s essential to clean and replace the filters on your heating, ventilation, and air conditioning (HVAC) system at least once a month. This prevents excessive wear and tear on your system and keeps it running smoothly. This can help make your heating system more efficient, often saving you money.

If you’re unsure how to clean your filters or whether your filters need to be replaced, search for an HVAC technician nearby.

5. Thermostat Issues

The thermostat is the control system that monitors your home’s temperature. When the HVAC system is working correctly, the thermostat is, too. But when the thermostat is not working correctly, the system can’t function properly.

If your heat is not working, check your thermostat. Is it set to the correct temperature? If the thermostat isn’t set correctly, your HVAC system may not be functioning correctly.


If your home is getting colder or warmer than usual, or you notice a strange smell from your heating vents, you may have a problem with your hands. If you see any of these issues, a professional will determine whether your heating system needs repair or just a tune-up, and they can do the work to get your system working correctly.
