When to Call for Furnace Repairs in Atlanta

Regular maintenance reduces breakdowns, but even well-maintained furnaces can experience problems over time. From worn components to thermostat malfunctions, identifying early warning signs helps prevent costly repairs and cold nights.

Below, we outline the three most common furnace repairs our team handles each winter — and how to know when it’s time to call in the pros.

1. Blower Motor and Fan Repairs

Your furnace’s blower motor and fans circulate heated air throughout your home. When these parts wear down or fail, airflow is restricted, leading to uneven temperatures or no warm air at all.

You may need blower motor repair if:

• You hear unusual noises — such as screeching, rattling, or grinding.
• There’s no air coming from vents even though the furnace is running.
• You notice a burning smell during operation.

If you detect any of these signs, turn off your system and call Estes Services right away. Our licensed HVAC professionals will inspect and replace worn components, lubricate moving parts, and restore safe airflow throughout your home.

2. Heat Exchanger Problems

The heat exchanger is one of the most important components of your furnace. It transfers heat from combustion gases to your home’s air while keeping harmful fumes contained. Over time, cracks or corrosion can develop, allowing carbon monoxide to leak — a serious safety concern for homeowners.

Warning signs of a damaged heat exchanger include:

• Strong, unpleasant odors when the furnace is running.
• Soot buildup on walls or around vents.
• Higher energy bills due to reduced heating efficiency.

If you suspect a problem, shut off your furnace and contact a licensed HVAC technician immediately. Estes Services provides comprehensive furnace inspections, safety checks, and heat exchanger replacements for all major brands.

3. Thermostat Issues and Calibration

Your thermostat acts as the control center for your heating system, regulating temperature and comfort. When it malfunctions, your furnace may cycle inconsistently or fail to respond entirely.

Common thermostat issues include:

• Incorrect temperature readings or unresponsive controls.
• System short-cycling (turning on and off too frequently).
• Disconnected or corroded wiring.

Estes Services offers furnace tune-ups that include thermostat calibration, cleaning, and wiring checks. For homeowners interested in smart upgrades, we can also recommend energy-efficient thermostat installations compatible with your system.

Improve Your Indoor Air Quality This Heating Season

A well-maintained furnace not only improves comfort — it also enhances your home’s indoor air quality. Clean filters and ducts reduce airborne dust, allergens, and bacteria, helping your family breathe easier all winter long.

Estes Services also provides air cleaners, UV purifiers, and humidity control systems to complement your heating system for year-round comfort.
