Why is My Furnace Blowing Cold Air?

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.

Faulty Thermostat
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.

Leaking Ducts
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.

Valve Problems
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.

Age
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.

If your furnace is in need of a repair or replacement, our specialists at A-Plus Quality, HVAC services in the Greater Toronto Area, will be glad to help you. Contact us today!

  • We needed a new boiler fast and they were faster than the other places we got quotes from, they were more sincere, less sales-oriented , and they had more technical knowledge and were able to explain things in layman's terms. They were transparent in their pricing and everything came out as estimated after the boiler was replaced. They didn't try to sell us maintenance packages or anything like that, just gave us the service we needed. We feel lucky to have stumbled upon them.

FAQ

  • Why should I maintain my Furnace or AC?

    An annual maintenance will extend the lifetime of your heating and cooling unit. The technician will diagnose and repair any problem with the unit before it fails, so you won't need to worry about any problems when the weather gets very hot in the summer or extremely cold in the winter.

  • Furnace is blowing cold air in Winter?

    This can be due to Ignition lockout, sometimes could be resolved by resetting the power  and if this does not resolve the issue you should contact a certified gas technician from A-Plus Quality to get this problem resolved!

  • Water is Leaking on my Furnace

    Water falling on to the furnace can harm your heating unit by affecting the control boards and other components enclosed in the furnace. There can be many causes to the water overflow, but the most common cases in the summer is the ice build up inside the evaporator coil due to low refrigerant level. Water build up can also be due to the evaporator coil having a crack on the base, if this is the case contact us by booking an appointment or call us today to have a technician come have a look at your unit and repair this issue before it causes excessive damage.  

  • What is a mini-split?

    By definition, and simply put, a “Split System” is a heating and air conditioning system which has two main components, the indoor unit and outdoor unit. In short, the indoor unit absorbs heat energy in the cooling mode, and the outdoor unit rejects the very heat absorbed by the indoor unit. And the cycle is repeated until the set temperature is met. Although the indoor and outdoor units are located in physically different, hence “split” locations, they are connected and operate as, one system; continuously circulating refrigerant liquid and vapor by means of interconnecting, dehydrated copper refrigerant lines, commonly referred to as a “Line Set”.

  • How do I know what size unit I need?
    If you have any problems with your system, you should contact the contractor who installed the units. All our systems are covered by a 5 year parts, 7 year compressor limited warranty
