Inappropriate Temperature Setting

Should the thermostat be set too high, the furnace might keep running ceaselessly. If you think the temperature is too ambitious, consult an HVAC specialist for optimal settings for your system. Some homeowners mistakenly think cranking up the thermostat will warm their spaces quicker. In reality, this only boosts energy expenses. And if left unchecked, homes can become uncomfortably warm. It’s often recommended to avoid settings above 75 degrees in most regions.

Older thermostats, particularly those over a decade old, may have wiring issues. Pests like rodents can also harm wiring leading to the thermostat. To uncover any wiring damage, have an HVAC technician do an inspection.

Tinkering with your thermostat’s wiring is perilous. Incorrect handling might render the device useless, and given its connection to the house’s electrical network, it poses a risk of electrocution.

Air Filter Concerns

Clogged or dirty filters force the furnace to operate non-stop. Regular filter replacements can prevent this. If accessing the filter proves challenging, seek help from an HVAC technician.

Issues with the Furnace Relay Switch

A relentless furnace might indicate a need to reset the relay switch or that the switch is jammed. Trust an HVAC expert to evaluate and either reset or replace any malfunctioning relay switch to restore optimal functionality.

Sometimes, the relay switch contacts might fuse due to arcing, preventing them from working correctly. If there’s a visible spark inside, it’s likely this problem.

The Furnace’s Gas Valve

With extensive usage, the gas valve can get jammed, causing continued burning of propane or natural gas. This results in the constant circulation of warm air, raising the indoor temperature. Beyond elevated temperatures, a stuck valve with an accompanying gas leak poses significant threats. This situation may escalate to higher gas bills, potential fire hazards, explosions, or even carbon monoxide dangers. Address any gas valve issues with an HVAC professional to safeguard your dwelling and its inhabitants.
