Winter brings chilly temperatures, and in the Chicagoland area, we rely on our HVAC systems to keep us warm and comfortable. However, cold weather can create unique challenges for your heating system. At Doornbos Heating & Air Conditioning, we understand how essential a reliable HVAC system is during the colder months. Here are seven common cold weather HVAC problems and what you can do to prevent them.
1. Thermostat Malfunctions
Thermostats control the temperature in your home, but cold weather can sometimes cause them to malfunction. If your thermostat is not working correctly, your HVAC system may not heat your home to the desired temperature. Try changing the batteries, as this simple step often resolves the issue. If the problem persists, it may be time to upgrade to a newer thermostat.
2. Reduced Airflow Due to Clogged Filters
Cold weather HVAC problems often stem from clogged air filters. When the filter becomes dirty, airflow is restricted, causing your system to work harder and reducing its efficiency. This can lead to uneven heating and even system breakdowns. To keep your system running smoothly, replace your air filter every one to three months, especially during heavy-use winter months.
3. Pilot Light or Ignition Issues
Many older heating systems rely on a pilot light or an ignition switch to start the heating process. Cold temperatures can sometimes cause these components to malfunction. If you notice your system isn’t producing heat, check if the pilot light is out or if there’s an issue with the ignition. This is usually a job for a professional HVAC technician who can ensure everything is functioning safely and properly.
4. Heat Pump Problems
Heat pumps are designed to provide both heating and cooling, but they can struggle in extremely cold weather. When temperatures drop too low, the heat pump may not be able to pull in enough warm air from the outdoors to effectively heat your home. In this case, you may need a backup heating source, like an electric heater, or consider a dual-fuel system that switches to a gas furnace in extremely cold weather.
5. System Short Cycling
Short cycling is when your HVAC system repeatedly turns on and off without completing a full heating cycle. This can happen in cold weather if the system is overworked or improperly sized for your space. Short cycling not only affects comfort but also leads to higher energy bills and increased wear on your system. A professional HVAC technician can assess whether your system is properly sized and address any underlying issues causing short cycling.
6. Carbon Monoxide Leaks
One of the most serious winter weather HVAC problems is the risk of carbon monoxide leaks. Heating systems that burn fuel, such as gas furnaces, can produce carbon monoxide, a dangerous gas that is colorless and odorless. Regular maintenance is essential to ensure your system is venting properly. Installing carbon monoxide detectors throughout your home is also a wise precaution to protect your family.
Preventing Cold Weather HVAC Problems
Preventing winter weather HVAC problems starts with regular maintenance. Scheduling an annual HVAC tune-up with Doornbos Heating & Air Conditioning can help catch issues early, ensuring your system is ready to handle the cold months. During a tune-up, our experienced technicians inspect, clean, and adjust your system for peak performance. Doornbos offers regular maintenance plans that can extend the life of your system and give you peace of mind all winter long.
