With winter almost upon us, it’s imperative for your heating appliances to be operable. Otherwise, you’re liable to endure an unbearably chilly holiday season. Furnaces, specifically, can sometimes blow cold air, which is an unpleasant surprise for the owner. If your furnace is malfunctioning, it’s best to contact A-Plus Quality, HVAC services in the Greater Toronto Area. For insight on why your furnace is blowing cold air, below are some of the most common causes.
In most cases, the thermostat is the culprit. Whether it was improperly installed, the batteries are low, or it’s not compatible with your heating system, it’s crucial for an HVAC expert to diagnose the problem. With their professional guidance, they can pinpoint the issue and ensure that it’s resolved promptly.
Old Air Filter
If you haven’t changed the air filter in some time, it could be causing your furnace to overheat. When air filters get too dirty, they can compromise the airflow. As a result, it prevents the furnace from blowing hot air. After changing the filter, restart the furnace, and it should be as good as new.
If there are holes in the ductwork, hot air could be escaping from them. Without the necessary expertise, inspecting this problem can prove challenging. It’s for this reason why hiring HVAC services in the Greater Toronto Area is a must when addressing this complication. If the HVAC technician detects any leaks, they’ll know how to remedy the issue.
Over time, your furnace collects dust, dirt, and debris. When these impurities aren’t removed, they can bog down the system. More often than not, this leads to valve complications. With a thorough cleaning, your furnace will be in tip-top shape.
In some instances, old age is the problem. Though furnaces can last for about 15-20 years, they start to deteriorate after that. If you’ve had your furnace for several decades, consider investing in a new one.
