Why Is Your Heating System Not Blowing Hot Air?

Have you ever had this problem? You turn on your heating system to find only cold air blowing. Well, there could be several reasons why your unit is not working properly.

Here are some potential causes and quick fixes you should know:

Thermostat Issues

The problem may be hiding in your thermostat. It could be caused by dirt buildup, incorrect settings, or dead batteries. Here are some things to troubleshoot:

  • This may sound simple but make sure it is set to “heat.” You wouldn’t believe it but this is among most of the service calls.
  • Check the batteries and replace them if needed.
  • Open the thermostat panel and clean your thermostat using a soft brush.
  • Ensure that it is installed in the right place, not near an air vent or direct sunlight.

If none of these fixes work, it may need a replacement.

Wrong Sized System

Many homeowners assume that a bigger furnace is always better. Contrary to this belief, size does matter in this situation. An oversized system will cycle on and off, causing inconsistent temperatures. On the other hand, an undersized unit cannot effectively heat your home, which can lead to high bills.

Having the right size of your heating system can make a big impact to your home’s comfort and savings. So if you need help with the sizing, reach out to your trusted HVAC company.

Clogged Filter

When your filter is clogged with dirt and other debris, it causes your unit to malfunction, blowing cold air instead of hot air. It’s also the reason why your heating bills snowball. To ensure good airflow and proper system operation, be sure to change your air filter regularly. 

Leaking Ducts

Another reason why your home is freezing could be caused by clogged or damaged ductwork. Have your air duct inspected by your local HVAC contractor. It may need professional cleaning, sealing, or repair. Never take a chance to get it fixed by you or put your safety at risk, unless you’re a certified technician.

The Pilot Light is Out

If you’re using an old furnace, you may also want to check its pilot light. A gust of wind can blow the flame out. In that case, you can try to relight it by following the manufacturer’s manual or guidelines. If you’re not comfortable doing that, bring in the experts to inspect your furnace and provide you reliable solutions.

Weird Furnace Odors You Shouldn’t Ignore

Odd smells coming from a heating system is downright worrisome.  Most homeowners are not aware of what these weird odors mean. They assume that there could be a mechanical problem or some serious issues. Either way, these unusual furnace smells require immediate attention.

Know what they are and what you should do about them through this post.

Musty Odors

A musty odor could be caused by dirt or mold growth in your ducts. This is particularly true if you haven’t had your ductwork or system cleaned regularly. Routine check and service from the pros can prevent this problem and ensure your unit works properly. If the damp smell doesn’t dissipate, the issue could be coming from another part of your home.

Rotten Eggs

Does your furnace smell like rotten eggs? A cracked heat exchanger may be to blame! It’s a pretty serious problem that can put you and your family’s safety in danger. It increases the risk of fire-related hazards and carbon monoxide poisoning. In that situation, the first thing you should do is turn off your heating system.  Evacuate your home immediately then call 911.

Burned Dust

You may be wondering why your furnace smells like fuel. That is normal when you turn it on for the first time. However, a burning dust scent is caused by the dirt that settles in your unit when it is not in use. For a quick fix, change your filter. If the odor doesn’t go away, contact the experts to get the issue resolved.

Metallic Smell

An electrical or metallic smell is a result of an overheating component in your system. It can be caused by frayed wires or broken motors. Trying to fix it on your own can make the situation worse, not unless you’re a NATE-certified technician. We suggest that you bring in the pros to handle the job for you.

Some Preventive Maintenance Tasks

Did you know that a little extra care can go a long way? These maintenance tasks are your ticket to a worry-free winter season.

  • Change your filter every month.
  • Keep your air vents free from any obstruction.
  • Schedule a routine furnace checkup.
  • Calibrate the thermostat.
  • Add or replace your insulation, if needed.
  • Get a professional duct cleaning service.
