It’s tempting to put off repairs for a malfunctioning heating system as long as the equipment continues to operate. Unfortunately, you may not realize that delaying repairs is increasing energy waste and damaging additional parts in the system. 


Instead of fearing a surprise bill, asking for a free furnace repair estimate can help you address the problem expeditiously in Granville.


Poor Heating Performance

Your furnace should maintain a consistent indoor temperature. If you’re regularly adjusting your thermostat because you feel chilly, you should schedule a free furnace repair estimate. An HVAC technician can determine whether the problem is a miscalibrated thermostat, an electrical issue, or obstructed airflow. 


Changes in Heating Cycles

Short and repetitive cycles suggest that the furnace is overheating and turning itself off. Longer and more frequent cycles tell you that the furnace can’t keep up with your heating needs. In either case, you’ll need an HVAC technician to diagnose and repair the problem before it worsens. 


Yellow Burner Flames

A healthy furnace will have bright blue flames. The system will produce yellow flames when something interrupts the combustion process and there’s less oxygen mixing with the gas. As a result, the system produces more carbon monoxide. Having an HVAC technician clean the burners will usually correct this problem. 


Cracked Heat Exchanger

Regularly test and check your carbon monoxide detector to keep an eye on exposure to this toxic substance. In some cases, an older furnace’s heat exchanger will crack and leak carbon monoxide into your home. Your technician will have to replace the heat exchanger before you can resume the safe operation of the furnace.


Unusual Noises

Your furnace should remain quiet even when it’s running a heating cycle. Any disruptive noise should encourage you to schedule furnace repairs. A screeching noise indicates a worn drive belt. Clogged burners can produce a booming noise. Humming noises suggest a problem with the blower motor. 


Your HVAC technician can quickly diagnose the cause of the noise and offer repair solutions.
