7 Signs It’s Time to Bring In the Heating Experts

A problem with your heater could leave you out in the cold and facing costly replacement expenses. If your home or business experiences any of the following seven issues, it’s time to contact a local heating expert to inspect your heater. A Casteel technician can ensure your heater gets back up and running properly.

Higher Energy Bills

Have you noticed an increase in the amount you’re paying each month on your utility bills? The cause could be your heater. When your unit needs repairs it heats less efficiently, meaning it takes more energy to heat your home, costing you more each month.

Can’t Remember When Your Last Service Was

Was the last time your heater serviced so long ago you can’t even remember it? If the answer is yes then it’s time to get your heater tuned up by a professional.

Yellow Pilot Light

The pilot light in your heater should be burning bright blue. If it’s burning yellow instead, you need to contact an HVAC expert to check for a possible carbon monoxide leak.

Dirty Filters or Vents

Filters help your heater achieve maximum efficiency. If you’re noticing dirt around your vents, you could have a dirty filter, which can decrease the air quality and make your heater work harder.


Heaters typically last 15-20 years. If your heater is getting up there in age, it could be time for service to keep it working properly or look into a unit replacement.

Unusual Noises

Creaks, squeaks, and other unusual noises mean a component in your heating system is loose. Fortunately, our team provides dependable furnace repair services in Gainesville, Savannah, Athens, Newnan, Atlanta, Marietta, and other areas of Georgia. We will perform an inspection of your heating system to diagnose the source of the noises and fix the issue. Get your furnace inspected by a heating expert who can make sure everything is in working order.

House Takes a Long Time to Heat Up

When it takes longer than usual for your home to heat up, your heater needs to be serviced. Don’t delay in getting a heating professional out to inspect your unit.

Common Types of Furnace Problems

The heating technicians at Casteel can diagnose your heater and make any necessary repairs. If you’re experiencing a heater problem, it could be from one of these four common issues. Our technicians can assist in the inspection, diagnosis, and repair of your heating system.

Repeatedly Cycling On and Off

If the heater is frequently cycling on and off when it should be dormant, you could end up paying more on your utility bills. The cause could be a dirty filter or clogged airflow, but a technician can accurately diagnose the cause of the problem.

Cracked Heat Exchanger

The heat exchanger in your furnace keeps the system running safely by keeping the heat separate from gas. The heat exchanger can crack over time without proper maintenance and result in a gas leak in your home. Our contractors provide innovative furnace repair services in Atlanta, GA and other areas and have the tools necessary to fix or replace the damaged heat exchanger in your heating system.

Broken Blower Belt

If you’re hearing a high-pitched squealing sound when your heater is running, the issue could stem from the blower belt. This keeps the fan in the heater working, and over time it can get worn and break. A heating technician will be able to replace this belt for you.

Damaged Limit Switch

Any damage to the limit switch could make the blower stay on continuously. A Casteel technician can properly repair or replace this piece.
