Why Furnace Repairs Shouldn't Be Delayed

Delaying furnace repairs can lead to more significant issues and costly repairs in the future. Here are some reasons why addressing furnace problems promptly is essential:

• Prevents Bigger Breakdowns: Fixing minor issues early can prevent major breakdowns later.
• Improves Energy Efficiency: A well-maintained furnace operates more efficiently, saving you money on energy bills.
• Ensures Safety: Timely repairs help avoid dangerous situations like carbon monoxide leaks, ensuring your home remains safe.
• Extends Furnace Lifespan: Regular repairs and maintenance can significantly extend the life of your furnace.

Pro Tip: If you hear unusual noises or notice poor heating performance, call a professional to inspect your furnace before it gets worse.

Signs You Need Furnace Repair

Not sure if your furnace needs repair? Here are some common signs that indicate it’s time to call a professional:

• Uneven Heating: Some rooms are warmer than others, signaling issues with airflow or the furnace itself.
• Strange Noises: Unusual sounds like banging, rattling, or squealing could mean a mechanical issue.
• Frequent Cycling: If your furnace turns on and off more frequently than usual, it could be a sign of a malfunctioning thermostat or other issues.
• Increased Energy Bills: A sudden spike in heating costs without a change in usage could indicate your furnace is working harder than it should.
• Pilot Light or Flame Issues: A yellow or flickering flame could point to a dirty burner or airflow issues.

Understanding Your Furnace's Ignition System

Older gas furnaces used a manual pilot light as an ignition source. A regulator supplied a small flow of gas to keep a short flame burning so it would be ready to ignite the gas when it was time to heat the home. More efficient and modern gas furnaces use a “hot surface ignitor” made of silicon nitride as the ignition source. Electricity passes a current through the glow stick only when the furnace calls for heat. either 120v or 240 depending on the system.

Maximizing Efficiency with a Heat Exchanger

A heat exchanger mounts above the combustion chamber. This allows the exchanger to absorb as much heat as possible from the combustion process. The cold air inside the exchanger warms almost immediately as the heat from the combustion process rises into the exchanger. Once that air reaches a level preset by the furnace manufacturer, relay kicks in and powers a blower fan that forces the warm air into the home’s heating ducts and out through the registers. The combustion sequence ends before the blower motor stops. This allows the blower to distribute every bit of warm air into the home before the cycle is complete.

Safe Management of Combustion Byproducts

The byproducts of combustion include carbon monoxide and other harmful gases, as well as a small amount of unburned natural gas or propane. High-efficiency gas furnaces capture the exhaust gases and compress them before igniting them in a second combustion chamber. This squeezes every bit of energy from the unburned gases. Any remaining byproducts must be vented away from your home, typically through a flue. 

It is important to have your heat exchanger checked annually to protect your family from breathing in unwanted co-gases.
