Does Your Furnace Need to be Serviced if it’s Blowing Cold Air?

Returning home from the chilly outdoors, the last thing you expect from your furnace is cold air. While this isn’t an uncommon occurrence, it could indicate a couple of issues with your furnace, but it’s usually not dire. However, if cold air from the furnace persists, you may need to have your furnace serviced to correct the problem.

What does it mean if a furnace is blowing cold air?

Naturally, a furnace is designed to warm the house by pumping warmed air into the home to maintain a warm barrier from the cold outside of the home. Sometimes cold air is produced instead which can be caused by something as simple as the mechanisms just warming up or it could indicate that core components are incorrectly functioning. Let’s dive into what this cold air could indicate in your furnace and some ways you can deal with them.

Thermostat Setting

One of the simplest explanations of cold air production is that your furnace’s thermostat is set to ON. This makes the fan constantly blow air non-stop even as the furnace is working. Therefore, the furnace will blow cold air because the heat generation is being canceled out. This can easily be fixed by switching the fan to AUTO. This regulates the airflow in order for the furnace to generate heat and not have constant cool air circulation to contend with.

Warming up

It takes a little time for the furnace to generate heat. As the unit begins to work you may feel cool air from the vents instead of heat – but this is just the initial stage of the process. The air should heat up after a few minutes as the furnace mechanics generate warmth, but if it doesn’t, go ahead contact furnace specialists to get the unit looked at for internal problems.

Clogged Air Filter

When the furnace’s air filter is blocked with dust or other debris, it can inhibit the spread of warmth into your home. This can cause the unit itself to overheat instead of dispersing the warm air into your home, leaving you with only cool air that just escapes the blockage. This is also a major fire hazard. If this blockage continues, the heat and debris could combust, resulting in a fire spreading throughout the system and into the house itself. This is easily avoidable by thoroughly cleaning the filter system. You can take out and clean the filter yourself but sometimes it is helpful to have a furnace specialist, like Exxel Mechanical, service it for you and inspect the entire system. Not only will you get a more in-depth cleaning, we can identify whether there are additional problems with the overall furnace system.


Pilot Light Issues

Cool air may be coming from the furnace simply because the pilot light is OFF. No pilot light, no burners, no heat. You can go in and manually switch the pilot light on by turning off the furnace (no heat), going to the bottom of the assembly switch, and turning the pilot light ON. If it’s on but not working, switch it to off, wait a few seconds, and then switch it on again. Carefully check to see if gas is flowing, then carefully light it with a lighter. If the gas flow is steady, you should be able to turn the heat on and get warm air. If this doesn’t work, or if you’re unsure about the process, seek professional help. Be careful and do not risk your safety.
If the furnace unit is only producing cold air, despite your minor fixes and adjustments, you need to seek professional furnace repair or routine servicing.

Seek Furnace Repair Servicing

Prolonged issues could lead to other problems down the road and could jeopardize your home’s safety as well as comfort. This could also be an indicator of other mechanical problems like a faulty circuit board, igniter failure, or more intensive issues. Remember, mechanical issues in the furnace can lead to fire or other safety hazards. Instead of stressing about this though, why not just ask HVAC professionals to take care of your technical problems? Besides ensuring long-lasting heat from your furnace, you’ll have peace of mind knowing that it’s functioning safely and correctly. Servicing your furnace will also preserve the unit for years to come, ensuring mechanicals issues are fixed before they turn into major, expensive problems.

What Does Furnace Servicing Do and How Often Do You Need It?

It’s easy to overlook heating while it’s still summer, but when fall and winter hit, will your furnace be ready? Just like your air conditioner, the constant use of your furnace over the years can generate some general wear or worse. The need for furnace repair is actually quite common leading into the cooler autumn period, as the system is restarted.

You can avoid the more expensive furnace repairs by simply having the furnace serviced to prolong the life of the unit.

What Does Furnace Servicing Do?

Furnace Servicing is a thorough process designed to keep the unit clean, functional, and most importantly, safe. Furnace maintenance has multiple layers to the procedure, involving highly specialized technical skills needed to identify potential issues and service the respective components. This can range from simple filter cleanings to lubricating the central components. Furnace servicing is quite thorough but here are just a few of the tasks involved:

  • Clean the vent and air filter system for leaks or blockages, removing dirt and grime.
  • Inspecting the blower access door to ensure a secure seal.
  • Clean and inspect pilot assembly, the thermocouple, and/or the flame sensing rod.
  • Check for cracks and other damages in the heat exchanger to prevent carbon monoxide contamination.
  • Inspect gas piping and valve operation.
  • Inspect duct connections.
  • Amp-draw testing on the blower motor to see if it is performing to unit specifications.
  • Examine the flame sensor for proper ignition smooth performance
  • Apply lubricant to the motor’s moving parts.
  • Ensure all electrical connections and wirings are secure and not at risk of corrosion or rust.
  • Confirm the unit’s safety measures are functioning properly.
  • Repair circuit board.
  • And more….


Benefits of Furnace Servicing

Furnace servicing is important not only for keeping you and your home warm but also for preventing serious harm to your family and property. Because of its heating components, furnace technology does carry the risk of causing a fire if not maintained efficiently. Over time, lack of maintenance can increase the chance of the furnace mechanics breaking, which, coupled with the heat generation, could lead to a fire starting and spreading within the home. This can be caused by a combination of issues. For example, if dust is clogging up the flue, the heat from the generator can combust to start a fire and/or release poisonous fumes like carbon monoxide. The same mechanisms that keep your family warm can cause other serious issues if not treated, but this CAN be avoided with routine servicing.

Keeping furnace components lubricated, functional, and clean is vital to preventing both health hazards and more intensive damage. Additionally, having your furnace serviced also prolongs the life of your furnace overall, saving you up to $5,900 on a replacement furnace. And of course, your home will be warm and comfortable during the damp and cold periods of fall and winter.

Stay Cozy, Save Money, Maintain Your Furnace

Having your furnace serviced and maintained regularly can save you a lot of money and discomfort in the long run. Besides protecting your family from danger this is a great way to add value to your home. Whether you’re looking to sell your house or live in it for the long haul, this keeps the cold out and your expenses down.
