Homeowners rely on their heating and cooling systems all year long. As temperatures drop to near freezing or freezing levels in the wintertime, it’s very important that your gas or electric furnace is working when you need it the most. Every so often, heating systems may not function as they should. Thankfully, homeowners can fix most of the common furnace problems that can arise. Here are some troubleshooting tips to help you diagnose and potentially remedy some common furnace problems. When in doubt, contact an HVAC contractor who specializes in furnace repair in Sarasota.
Understand Your Heating System
Before you can start troubleshooting your furnace, you have to understand how it works. Your central heating system is composed of a network of ducts and vents that’s connected to an airflow fan. This system is controlled by a thermostat, which can be programmed to turn on and shut off automatically, thus regulating your home’s ambient temperature based on a desired temperature setting.
Check for a Viable Power Supply
If your furnace doesn’t turn on when it’s supposed, or if it suddenly shuts off, check to see that your system is receiving power. In some instances, your HVAC system’s circuit breaker may have been tripped, which happens when there’s a power outage or a power surge. Also, check your thermostat if it’s connected to your home’s electrical panel. If the breakers have been tripped, reset them to restore power to your furnace.
Check Your Thermostat
Your system’s thermostat relies on sensors to regulate the ambient temperature of a room. If the sensor or thermostat malfunctions, your furnace could run continuously, causing your monthly utility bills to skyrocket. Refer to your thermostat’s user manual for troubleshooting advice.
Make Sure Your Furnace’s Pilot Light Is On
Older furnaces have pilot lights, which may go out. If your unit is running but is not heating, or if you smell gas, make sure your pilot light is lit—in the case of gas, don’t light your furnace until after you’ve shut of your furnace and have aired out your home. If your furnace is newer, inspect its electronic ignition mechanisms. Refer to your furnace’s user manual.
