How Do I Know If My Heater Needs Repair?

When Scottsdale’s winter temperatures cool things down – especially at night – you rely on your heater to keep your home comfortable. But if you’re feeling a chill indoors or your heating system isn’t performing like it should, it may be time for repairs.

Knowing the early signs of heater trouble can help you avoid bigger issues and unexpected breakdowns. Here’s what to watch for and when to call in a pro for help!

What Are the Most Common Signs That My Heater Needs Repair?

If your heater isn’t working as it should, look for these telltale signs:

• Inconsistent heating
• Reduced or poor airflow
• Frequent cycling
• Odd noises or odors
• Lack of heat
• Higher energy bills

SAFETY FIRST: If your carbon monoxide detector goes off or you suspect a gas leak, leave your home immediately and call emergency responders. After ensuring your family’s safety, contact a professional HVAC tech for repair.

Why Is My Heater Blowing Cold Air?

If your heater is running but blowing cold air, a few issues might be to blame:

• Double check that the thermostat is set to “heat” and not “cool” or “fan.”
• If you have a gas-powered system, a problem with the fuel supply can prevent the heater from producing heat.
• Clogged air filters can cause your system to overheat and shut off as a safety measure. Replace the filter and see if the problem improves.

If these quick checks don’t solve the issue, it’s time to call a professional for a closer look.

What Should I Do If My Heater Is Making Strange Noises?

While a heater typically makes subtle whirring or clicking sounds during normal operation, unusual noises are a red flag. Here’s what different sounds might mean:

• Banging or popping are often caused by expanding ductwork or a delayed ignition.
• Rattling suggests loose panels or components could be vibrating inside the system.
• Buzzing is usually the cause of electrical issues or failing components.
• Groaning or squealing may mean worn-out blower belts or motor bearings.

If your heater is getting noisy, turn it off and call a technician to prevent further damage.

Are My High Energy Bills Related to Heater Problems?

Unexpected spikes in your energy bills can often point to heater issues. While a temporary cold snap can cause increased usage, gradual or unexplained increases in your heating costs may signal:

• Reduced efficiency due to dirty filters, worn components, or poor airflow that are forcing the system to work harder.
• Aging equipment, as older heaters naturally lose efficiency over time and need repairs or replacement.

If you notice rising energy bills without significant changes in weather or usage, have a professional inspect your system.

When Should I Call a Professional for Heater Repair?

Call a professional anytime you notice unusual behavior from your heater – whether it’s inconsistent heat, strange noises, or unexplained shutdowns. Addressing problems early prevents costly breakdowns, keeps energy bills manageable, and ensures your home stays comfortable all winter.

How Can I Be Proactive?

It is always smart to be proactive by scheduling a preventative maintenance appointment! Regular maintenance reduces the risk of unplanned breakdowns and ensures efficiency all season.
