The Benefits of a New Furnace

When you upgrade to an new, high-efficiency furnace you'll reap the rewards, in more ways than one.

Newer furnaces burn fuel more efficiently. That means they don't run as often or for as long as an older model. They reduce waste, so you'll notice a difference in your monthly heating bills - and you'll be doing your part for the environment by reducing emissions.

Furnace Repair Parts

Furnace Parts Why this Furnace Part might fail and need repairs
Furnace Blower Motor & Wheel Circulates household air

  • Motor electrical failure
  • Worn or seized motor bearings diagnosed by either a noisy blower or blower running below normal speeds
  • Wheel defective or our of balance
  • Dirty blower motor or wheel

Both blower wheel and blower motor will be replaced when the furnace blow motor need replacing. This can limit annoying blower noise and prevent premature failure of the replacement motor bearings.

Furnace Circuit Board Controls operation sequence of cooling & heating modes & monitors system safety

  • Fails because of age
  • Excessive amp draw from a failed component
  • Power spike or lightning strike
  • Water damage from an external source
  • Cold solder connection
  • Burned out or shorted coil
  • Loose wiring connections

Very often, a failed furnace circuit board is only one component in a chain of failed controls. Sometimes it can be difficult, if not impossible, to locate all of these component failures in on a single service call. Trying to salvage suspicious components in an effect to reduce costs may actually wind up costing more in future furnace repairs.

Furnace Delayed Burner Ignition Main burners fail to ignite completely or promptly

  • Low gas pressure
  • Dirt in burners or orifices
  • Improper positioning of pilot burner or igniter
  • Burners out of position

Delayed gas ignition can be a serious problem. Light-off / cross-over burners must be properly aligned. Flue passages must be checked and burners properly adjusted by your service professional. If your furnace is over 10 years old and has a delayed ignition problem, it is wise to replace it. Today's furnaces utilize much safer gas ignition systems than those of older units.

Furnace Gas Valve Controls gas flow to main burners

  • Shorted or open circuitry
  • Mechanical failure
  • Intermittent failure

There are many types of gas valves in use today. Often, failure of one component in the gas control system can affect the dependable performance of other components. Replacing the gas control system makes good repair sense. If we discover that you have a non-100% shut down gas control system in your furnace, it must be replaced, not repaired. Older gas systems are outdated and unsafe.

Furnace Heat Exchanger Separates combustion gases from household air

  • Cracks caused by stresses within the furnace and/or excessive heat from a over-sized furnace, over-firing furnace, air restrictions, or inadequate duct system
  • Holes / Severe Rust or Pitting caused by condensation within the heat exchanger produced by an undesized furnace, under-firing furnace, frequent cold start-ups, or corrosive ambient air

A safety inspection if performed on the heat exchanger every time we perform furnace repairs or maintenance service. An infrared heat exchanger inspection should be an annually scheduled procedure. Your family's safety depends on it.

Furnace Hot Surface Ignitor The flame light-off device for most modern furnaces

  • Age (most igniter’s only last 3 to 5 years
  • Short cycling (usually caused by dirty or weak flame sensor
  • Any direct contact or impact (igniters are extremely fragile)
  • Dirty flame sensor

It if critical to have your flame sensor cleaned every season. Failing to do so will cause the hot surface ignitor to cycle too frequently as it attempts to light the furnace burners. This, in turn, causes the HSI to burn out prematurely. Annual furnace maintenance makes sense. It can actually cost less to maintain a furnace than to replace the HSI every one or two years.

Furnace Inducer Blower Assembly Provides draft for high efficiency furnaces rated 80% and 90%

  • Worn motor bearings
  • Object obstructing blower
  • Shorted or open circuit in blower motor
  • Defective or out-of-balance blower wheel
  • Rusted or corroded housing
  • Pressure tap plugged

Most inducers are provided as complete assemblies by the manufacturers. We agree with that approach and strongly recommend not only replacing Inducer motors or other Inducer parts. Many times a faulty pressure switch can cause an Inducer to fail prematurely.
