When winter hits and temperatures start dropping, there’s nothing worse than realizing your furnace isn’t kicking on. A malfunctioning furnace that fails to heat up leaves you and your family shivering throughout the home, no matter how many blankets you pile on. Before you panic and worry about replacing the entire HVAC system, call a knowledgeable furnace repair Las Vegas specialist. An expert heating contractor can efficiently diagnose the issue and likely fix it for a reasonable rate. This article will cover the top reasons your furnace may not be heating up properly and how a pro can get your unit up and running again.

Old Thermostat Needs Replacing

If you have an outdated thermostat that relies on older mechanical technology instead of smart digital controls, it may stop working properly after years of use. Signs that the thermostat is faulty include inconsistent temperature readings or failure to trigger the furnace even when set substantially higher than the indoor temperature. A contractor can determine if replacing it with a modern, programmable thermostat will resolve furnace issues.

Pilot Light Repeatedly Goes Out

Gas furnaces have a small pilot light that ignites the burner to produce heat. If this light goes out repeatedly, it won’t signal the furnace to start up when needed. A repair tech can troubleshoot pilot outages by examining the thermocouple and gas control valve responsible for regulating the pilot flame. Fixing minor pilot issues takes little time but makes a major difference in furnace functionality.

Filter Needs Changing

It’s easy to overlook a dirty, clogged air filter as the culprit behind a furnace failing to heat up. But a buildup of dust and particles prevents proper airflow and functioning. HVAC contractors recommend changing filters once a month during busy heating and cooling seasons. Taking this small step goes a long way toward preventing furnace problems and keeping systems running optimally.

Blown Fuse or Tripped Circuit Breaker

Check the furnace circuit breaker or fuses if your system fails to turn on. Issues like power surges or electrical faults can blow fuses or trip circuits breakers, cutting power to the furnace. Resetting breakers or replacing fuses may resolve the heating issue in these cases. Most homeowners can handle this basic fix themselves. But if you need to reset breakers or replace fuses frequently, contact a professional to inspect for underlying electrical issues.

Faulty Blower Motor or Fan

The blower and fan inside a furnace must spin to push heated air through ductwork and circulate it throughout your home. If these parts malfunction due to age, wear and tear, or damage issues, the furnace won’t adequately heat rooms even while running. Skilled technicians have specialized tools and testing capabilities to evaluate furnace fans and blower motor operation. They can repair or replace defective parts to get everything working again.

Dealing with a furnace that fails to heat your home properly is extremely frustrating. But in many cases, relatively minor repairs like replacing a faulty thermostat, relighting an extinguished pilot light, changing clogged filters, or resetting tripped breakers can have the unit back up and running at full capacity. When you lack the time or ability to adequately troubleshoot furnace issues, don’t waste the entire season shivering. Call a knowledgeable local heating contractor who can efficiently diagnose problems and expertly complete necessary repairs for reliable operation all winter long.
