Incorrect Thermostat Setting
Believe it or not, but even in today’s modern time, most people still fail to set their thermostat correctly—and it’s one reason why a furnace releases cold air. As a rule of thumb, your thermostat must be set to “heat”.
If your thermostat is battery-operated, be sure to check the batteries and replace them when necessary. The best way to ensure your thermostat and furnace are always in great shape is with the help of expert furnace services in Plano, TX.
Overheating Due to Dirty Filters
When was the last time you changed your air filter? Dirty and clogged filters may result in overheating. A neglected furnace won’t work as expected because it’s either the filters are inefficient or some parts are faulty or damaged.
As a precautionary measure, you have to change the filters at least once a month to prevent clogging. Also, don’t forget to give your furnace some time to rest.
Valve Problem
If it’s not the filters or the thermostat, then a faulty gas valve could be the main reason why your furnace is blowing cold air. The dirt and debris that have amassed might be restricting the valve to operate as it should. Always check and clean the furnace valve to make sure that it runs efficiently. Calling a licensed HVAC technician can help you figure out the issue with the valve and restore your heating system.
Leaking Ducts
When you feel a cool gust of wind from your furnace, you can assume that the culprit is a leaky ductwork. With cracks and holes, the warm air could be escaping somewhere in the ducts before it even reaches your heating system. It would be best to consult a professional to assess your air ducts. They will tell you if it needs repair or replacement to address the leaks.
Faulty Flame Sensor
Your furnace’s flame sensor plays a significant role in providing your room the level of comfort it needs. As your heating system ages, grime and debris may build up—causing your furnace to blow cold air. With this, the sensor would require deep cleaning or replacement from the experts.
Dirty Gas or Oil Burner
Over time, dust and dirt will accumulate within your gas or oil burner, which can cause trouble in igniting. Consult a professional to remove all these unwanted grimes so your furnace will operate without any issues.
Obstructions Around the Furnace
Make sure to check for boxes, furniture, and decorations that are blocking your furnace. These obstructions can restrict the airflow from your system to the vents—preventing you from being comfortable.
Regular Maintenance Prevents These Problems
Most of the issues could be prevented with periodical or annual scheduled maintenance. Even though some of these furnace problems don’t require too much time and effort, it is still best to consult certified furnace services in Plano, TX. Hiring the professionals guarantees that your HVAC will receive the best care and maintenance because know how to handle every issue that comes your way.
