Combat HVAC Smells With Furnace Repair

Have you noticed a foul odor coming from your heater recently? Many homeowners experience this common problem, and it can be both unpleasant and concerning. But before you panic, know that there are several reasons why your unit might have a smell. If you’re ready to take back your fresh-smelling and clean air, Air Tech of Pasadena is here to help!

Causes Of Odors From Your Furnace

There are a lot of reasons why your furnace may have a sudden aroma. Understanding these causes can help you determine when to schedule a repair service.

Dust Buildup

One of the most common causes of a smelly furnace is dust buildup. When your unit sits idle during the warmer months, dust and debris can settle inside it. When you turn on your system for the first time in the fall or winter, this built-up dust burns off, resulting in a temporary burning smell.

Mold Or Mildew

If the odor coming from your heater is a musty or damp smell, it could be due to mold or mildew growth. This issue can occur when moisture accumulates in your system, often due to condensation on the coils or ductwork. When this issue occurs, our experts will provide a solution to solve the problem.

Dirty Air Filters

A clogged or dirty air filter can cause a burning smell to come from your system. As the filter restricts airflow, it can cause the system to overheat. Regularly changing or cleaning your air filters can help prevent this issue from occurring in your home.

How To Prevent Heater Smells

Once you’ve identified the source of the odor, there are steps you can take to prevent it from happening in the future. Our HVAC technicians are prepared to assist you with top-notch repair services.

Change Your Air Filters

Dirty air filters can cause a smelly heating unit. Make sure to check your air filters regularly and change them every three months, depending on usage. If the filter is reusable, clean it according to the manufacturer’s instructions.

Schedule Regular Maintenance

Regular maintenance is crucial for keeping your unit running efficiently and preventing issues, including foul smells. One of our professional technicians can inspect and clean your system, ensuring that everything is working properly.

Keep Your System Dry

If mold or mildew is the culprit, try to keep your system dry by addressing any leaks or ductwork damage in your home. Additionally, if you live in a humid climate, consider investing in a dehumidification system for your HVAC system.

When To Call For Heater Repair

In some cases, the odor coming from your unit may indicate a larger issue that requires professional furnace repair services. Here are some signs to look out for:

  • The smell persists even after changing filters and regular maintenance.
  • You notice strange noises from your system.
  • The unit’s performance is poor.
  • Your energy bills are rising.
  • The odor is accompanied by smoke or visible signs of damage.

If you experience any of these issues, it’s best to call for professional repair services immediately. There is a high likelihood that these problems are a result of bigger issues than the smell alone, which can permanently damage your unit.
