Heating FAQs

How often should I have my heating system serviced?

To maintain safety, efficiency, and reliability, we recommend scheduling annual heating maintenance—ideally in early fall before colder temperatures arrive. A typical tune-up includes:

• Inspecting and cleaning burners or heat exchangers
• Checking thermostat calibration
• Testing safety switches and airflow
• Replacing air filters if needed

This preventive care reduces the risk of breakdowns, keeps your utility bills manageable, and can extend the life of your system. Wall Heating & Air Conditioning offers a convenient Club Maintenance Plan to keep your heating system performing at its best year-round.

What are the signs that my furnace needs repair?

Watch for these warning signs that your furnace may require service:

• Strange noises like banging, rattling, or screeching
• Inconsistent or weak airflow
• Thermostat settings that don’t match room temperature
• Higher-than-normal energy bills
• System turns on and off frequently (short cycling)
• Yellow pilot light (instead of blue)

Even minor issues can escalate quickly if ignored. At Wall Heating & Air Conditioning, our expert technicians are available 24/7 to diagnose and repair problems fast—restoring comfort and preventing further damage.

How long do furnaces and heat pumps typically last?

On average:

• Furnaces last about 12 to 15 years
• Heat pumps typically last 10 to 15 years

Lifespan depends on factors like installation quality, regular maintenance, usage levels, and climate. Systems that receive routine care and timely repairs often exceed their expected service life.

If your system is over 10 years old and facing frequent repairs or reduced efficiency, it might be time to explore high-efficiency replacement options. Wall Heating & Air Conditioning offers honest evaluations and energy-saving upgrade solutions.

What temperature should I set my thermostat in winter?

For comfort and energy efficiency, the U.S. Department of Energy recommends:

• 68°F when you’re home and awake
• Lower by 7–10°F when you’re asleep or away

Using a programmable or smart thermostat makes these temperature adjustments easy—automatically reducing heating costs without sacrificing comfort. Smart models also provide usage reports, filter reminders, and remote access from your phone.

Wall Heating & Air Conditioning can help you choose and install a thermostat that fits your home and lifestyle.

Why does my heater smell when I turn it on for the first time?

That burning smell you notice at the start of the heating season is usually dust burning off the heat exchanger or other components after months of inactivity. It should dissipate within a few hours.

However, if the odor persists, smells like burning plastic, or includes gas or oil scents, shut off your system immediately and call for service. These could indicate:

• Electrical issues
• Clogged filters
• Foreign objects in vents
• Gas leaks (which require immediate attention)

Wall Heating & Air Conditioning provides emergency service to address safety concerns fast.

What should I do if my heating system won’t turn on?

Start with these simple checks:

• Thermostat: Is it set to "heat" and at the desired temperature?
• Breaker panel: Look for tripped circuits
• Filter: A clogged filter can trigger safety shutoffs
• Pilot light or ignition system: Older models may need manual relighting

If these don’t resolve the issue, call Wall Heating & Air Conditioning for a fast and accurate diagnosis. We’ll restore your comfort and identify the root cause—whether it’s an electrical issue, motor failure, or safety switch.

What’s the difference between a furnace and a heat pump?

Furnace:

• Uses natural gas, propane, or electricity
• Generates heat and pushes warm air through ducts
• Best for colder climates with harsh winters

Heat Pump:

• Transfers heat from outside air into your home
• Works as both a heating and cooling system
• More efficient in milder climates like Georgia

Wall Heating & Air Conditioning offers both options and can help you decide which system best suits your home, comfort needs, and energy goals.

Why is my heater making strange noises?

Unusual sounds could point to:

• Banging: Ductwork expansion or ignition delay
• Whistling: Airflow restrictions from dirty filters or leaky ducts
• Grinding: Blower motor issues
• Clicking: Electrical control faults or failing igniter

While some sounds are harmless, others may signal serious problems. Don’t wait—have it checked by a professional. Wall Heating & Air Conditioning offers fast diagnosis and same-day repairs.

Should I replace my old furnace with a high-efficiency model?

If your furnace is:

• Over 10–12 years old
• Frequently breaking down
• Causing rising utility bills
• No longer keeping your home evenly heated
