8 Simple Ways to Know If You Need Heating Repair


In Greenville and Spartanburg Counties, homeowners depend on Waldrop for heating repair by licensed, NATE-certified HVAC technicians. Our team can handle any issue that may be affecting your furnace. But knowing who to call to fix your heating system is as important as knowing when to call. Here are eight ways to know if you should call a heating company.

1. Adjusting the Thermostat Doesn’t Turn On the Heat

Check the thermostat if your furnace isn’t running or providing enough heat. It may not be working if the battery has drained. Or, the settings may be wrong. If the system is set to “on”, the fan will run constantly even if your heater isn’t on, so cooler air may blow from the vents. If you switch it to “auto”, the fan and heater will run concurrently when the temperature drops below the set value. If not, there may be something wrong with the heater or thermostat.

2. Resetting a Tripped Circuit Breaker Doesn’t Work

All heating systems rely on electricity to some extent. A tripped breaker is a common reason for a unit to not work. Resetting the breaker in the main panel should allow the unit to turn back on. If the heater still doesn’t work, or the breaker trips again soon after, call a heater repair company to investigate the underlying cause.

3. The Furnace Doesn’t Respond When the Power Switch Is Turned On

A furnace has a power switch that looks like a regular light switch (if not, check the owner’s manual for its location/appearance). If the switch is off, just flip it back on and the heater should run. A heat pump switch is usually located on a wall outside your home near the outdoor unit. If it’s off, lift the metal flap (if your model has one) and flip the switch to the “on” position. Call for help if the heater doesn’t start in either of these cases.

4. The System Keeps Going On and Off

If the furnace turns on and off again too frequently, there could be one of a few different problems. It should run for about 15 minutes and then turn off for a bit, before cycling again. If it cycles rapidly, try changing the filter, especially if it hasn’t been replaced recently. Contact a professional if this doesn’t solve the problem.

5. The Unit Makes a Lot of Noise

A furnace should not make rattling noises, which may indicate a loose panel or internal component, or squealing sounds, which can mean the fan motor belt is worn or out of place. Grinding can mean you need a motor bearing repaired. Scraping, banging, thumping, and rumbling are other furnace sounds to be concerned about. A contractor can determine the cause and whether anything needs to be repaired, lubricated, or adjusted to resolve the problem.

6. Something Doesn’t Smell Right

If there’s a gas or rotten egg odor, immediately leave your home and call for help. Contact your local gas company first to stop the leak. Natural gas is explosive and a major health hazard. If the air blowing from the vents smells dusty or dirty, chances are you need a new filter. But if the odor persists after installing a new furnace filter, schedule service.

7. The Pilot Light Doesn’t Look Right

If your furnace has a pilot light, check it often. A furnace problem can cause the pilot light to keep going out. This can be caused by a clog or draft as well. The pilot light should also always be blue. If it is yellow or any other color, this can mean there’s a carbon monoxide leak. Call for help right away to address this immediate danger to your family.

8. Your Heating Bill Keeps Going Up

A sudden spike in your utility bill, and not the normal increase at the beginning of the heating season, often points to a furnace issue. Having it looked at by a professional will not only save you money. It can also spot potentially serious problems before they get worse, or more expensive to fix.

Call Waldrop to Schedule a Heating Repair

If the issue can’t be resolved by adjusting the thermostat, changing a filter, or resetting a circuit breaker, you need a technician to check it out. The heating repair specialists at Waldrop are trained and equipped to inspect any model of heater and find a solution to any problem.
