From Lake Robinson to Pelham Medical Center, we’re passionate about keeping homeowners safe and comfortable, no matter the season. Keep reading to discover seven reasons for your problem and how we can help.
1. Issues With the Thermostat
When a furnace or heat pump can’t produce heat in the winter, check the thermostat settings first. Sometimes, homeowners switch the mode to “auto” or “cool” without realizing it, making the system act more like a fan than a heater.
A thermostat can also have calibration or sensor issues. If it can’t communicate with the furnace or accurately read the temperature, it causes problems throughout the home.
2. Dirt Buildup on Air Filters
The effect dirty air filters have on an HVAC system highlights the importance of preventive maintenance. Change the filter at least once a month to avoid issues.
When the component accumulates debris, it restricts airflow. In extreme circumstances, it can damage various components that prevent the device from effectively heating the air.
3. Problems With the Ignition Components
When you have trouble with your Greer HVAC blowing cold air in winter, schedule service with a qualified technician to diagnose the issue. Devices often develop pilot light or ignition problems when homeowners use the system excessively or after many years of operation.
Both electric and gas devices can experience ignition problems. Only a certified HVAC technician should repair the components.
4. Faulty Electrical Connections
Even a gas heating system experiences electrical issues. Loose connections can cause a wide range of problems.
Check the circuit breaker to determine if the system lost power after an electrical surge or other problem. If that doesn’t work, the issue could reside with the control board, the heating element, or various other components. Never troubleshoot electrical complications yourself, as you could damage the device more or experience severe injury.
5. Blocked Airflow in the System
How do blocked air vents or registers lead to cold temperatures emanating from the system in Greer? It has the same effect as dirty filters. Reduced airflow means less efficiency and the draft has more time to cool before reaching each room.
So, how can you avoid blockages?
- Keep curtains and furniture away from vents and registers.
- Regularly clean dust off these airway entry and exit points.
- Remember to open vents after temporarily closing them.
6. Leaking Air Ducts
Much like how blocked vents restrict airflow, ductwork issues can lead to your HVAC blowing cold air in winter. Over time, ducts experience wear and tear and develop holes and other issues. The draft that travels through them leaks out and won’t feel warm when it reaches the vents.
How do you avoid this problem? Schedule a ductwork inspection and cleaning at least once every three years.
7. Broken Components in the Heat Pump or Furnace
Both furnaces and heat pumps are a complicated network of electrical and mechanical components. Whether from heavy usage, severe weather, or normal wear and tear, every piece could break. If none of the above causes explain your cold air problems, call a reliable HVAC expert to diagnose and fix the situation.
Best Practices for Preventive Heating Breakages
How can you reduce the likelihood an HVAC system blows cold air when it shouldn’t? Scheduling a yearly check-up is the most essential preventive practice.
Also, run the device moderately. The United States Department of Energy suggests keeping the thermostat at 68 degrees. To stay cozy, consider using blankets, wearing layers, and drinking hot beverages.
