A faulty heating system is nothing to joke about, even in Stuart, Florida’s balmy climate. Heat-related problems may feel relatively harmless, but some can put your home or business in danger. Do you know which furnace overheating symptoms to treat as HVAC emergencies?
Since Hawk Air Conditioning Repair & Service provides furnace repair services in Stuart, FL, we shared our expert insights with you below.
What Makes Furnaces Overheat in Stuart, Florida?
Your furnace might start overheating for several reasons:
- Thermostat malfunction: If your thermostat fails to signal the furnace to shut off, it can set the overheating problem in motion.
- Airflow restrictions: Cluttered vents or duct blockages prevent air from flowing freely, which forces the furnace to work too hard.
- Dirty system interior: Dusty components cannot let off excess heat.
- Overworked components: The harder furnace parts work, the more friction they create. Friction produces heat, which worsens the furnace’s overheating symptoms.
- Old age: Sometimes, excessive heat buildup comes from an outdated furnace.
An overheating furnace is a fire hazard that jeopardizes your property in Stuart, Florida.
Overheating Furnace Symptoms You Should Know About
How can you tell when your furnace is getting too hot for your safety and comfort? You might face the following furnace overheating symptoms:
- Tripped circuit breaker: When your furnace works too hard, its electrical demands may increase above safe supply levels.
- Blower fan failure: This component directs warm air into your duct network so that heat stays in place if it stops working. You’ll notice little to no air coming through your vents.
- Flipped high limit switch: The limit switch detects internal furnace temperatures. If it doesn’t monitor the heat levels, it may allow the furnace to overheat instead of shutting it down like normal. Check to see whether it’s in the correct position.
- Burning or smoky odors: Smells wafting through the vents are one of the more obvious furnace overheating symptoms. You might detect odors of scorched rubber, hot metal, or dirty smoke.
- Short cycling: A typical furnace cycle lasts around 15 minutes. Short cycling happens when each cycle lasts ten minutes or less. These cycles will repeat in rapid succession.
Now that you know what to watch for, you can learn some solutions to protect your furnace system and property.
What To Do About Your Overheating Furnace
Overheating happens because of airflow restrictions, faulty system components, and excessive filth. You can prevent and address internal heat concerns with:
- Regular air filter replacements: Change your furnace filter every three months to clean the air and encourage flow.
- Inspections for internal and external vents: Ensure the air has clear inlets and outlets. Check the indoor and outdoor intake vents, the exhaust vent, and the exit vents throughout your home for obstacles.
- Consistently updating your thermostat: Thermostats can last between 10 and 20 years. Keep yours calibrated and upgrade to a newer model if necessary.
- Promptly repairing your furnace: When you put off repairs, you place additional stress on other parts and increase the chances that your furnace overheats.
If there are obvious furnace overheating symptoms, why not schedule annual furnace maintenance in Stuart, Florida? Consistent professional tune-ups help you keep up with your furnace’s cleaning needs.
