Troubleshooting Common Furnace Problems

Schedule annual furnace maintenance in Prescott with a trusted company such as BCS Heating and Cooling.An ounce of prevention is worth a pound of cure. It may sound like an old cliché, but the words are very tried and true. At BCS Heating and Cooling in Prescott, we have seen circumstances where the repair or service call could have been avoided. Here is a basic list of common furnace problems. It’s easy for any homeowner to diagnose furnace problems.

•    Maintenance: Schedule annual furnace maintenance and inspections. Prevent problems and breakdowns with routine inspections. Your furnace will run more efficiently and reliably. Hire a professional before fall. He will get the unit ready before it’s cold and fix problems while they’re small. Do this before the busy winter season.
•    Filters: Dirty air filters reduce airflow, making a furnace work harder to circulate. A clogged filter may damage the limit switch. Change the filters once a month.
•    Wear and Tear: Normal wear and tear can cause airflow problems, heat control-related problems or even overheating. Let a professional handle any serious mechanical problems, otherwise you may void any warranty, or cause larger problems.
•    Electric Ignition or Pilot Control: A faulty ignition or pilot could make it difficult to heat a home. Thermocouple problems, drafts or clogs may cause an unlit pilot light. A draft may also cause failure. Leave ignition issues to the experts.
•    Thermostat: A faulty thermostat can lead to problems with the fan or comfort levels.  If the furnace isn’t heating, Check the battery level and replace if necessary. Also, make sure it’s in heat mode. Check the temperature and set it to one that’s higher than the current room temperature. If none of these work, it may need replacing.
•    The furnace doesn’t heat at all: Check the thermostat setting, power, gas or the pilot light.
•    The furnace doesn’t heat enough: Again, check the filter for clogs. Also, a furnace may not produce enough heat if the filter is the wrong size for the space.
•    Frequent cycling: Cycling between the “On” and “Off” could be improper airflow, a bad thermostat setting or dirty filter.
•    The blower constantly runs: This could be a problem with the limit switch, which a professional may need to replace. The fan setting should be on Auto. In the On, Low, Medium, or High modes the fan will run continuously.
•    The furnace is too noisy: Rumbling, squeaking and rattles aren’t normal. It could be a mechanical problem, airflow reductions or a clogged burner.
•    Check the circuit breaker and power supply: Make sure the circuit breaker hasn’t tripped or blown a fuse. Also, make sure the power cord is plugged into an outlet.
