Emergency Furnace Repair?


Furnace repair service and install should be done by a certified contractor. It is important to have your furnace serviced or maintained annually. This will ensure operation safety, efficiency and longevity of your furnaceLocal building codes will specify the different types of furnaces that can be install. These may include restrictions on the placement of furnaces and minimum duct requirements. Codes also address special considerations and may even regulate the installation of burners to convert furnaces from oil or propane to natural gas.   

A heating system can be classified into two common ways; mainly by heat source and heat distribution. Most of these systems produce heat by burning oil, natural gas, propane or use an electric element. The most gas furnace heats the home by burning natural gas or propane. The heat then gets distributed by the blower motor throughout your home, delivering warm air to each room. The furnace is generally categories as Natural draft, Forced-air or Condensing. Most systems today are either Single-Stage, Two-Stage or Modulating.


Three Most Common Furnace

Single-Stage Furnace: Is a standard system which has only one stage of heating when running, during a call for operation. The output of these units are constant which means, these systems will use more energy comparing to other model furnace.

Two-Stage Furnace: A two-stage unit can produce two different levels of heating, allowing it to adjust heat output to meet the demand require. When less heat is required, a two-stage furnace will operates on the first stage, which uses less energy and thereby increasing efficiency hence lowering cost. Furnace would automatically turns on second stage heating and finish heating process.

Modulating Furnace: These are design with solid-state integrated controls which acts as the brain of the system and can modulate their heat output form 40 to 100%. Once there is a call for heat from the thermostat, the controls on the circuit board will initiate a sequence of events. This then direct the system to supply heat to the building efficiently.

Basic Components of a Furnace

  • Indoor Blower fan motor
  • Combustion blower motor
  • Heat exchanger
  • Burners
  • Gas valves
  • Pressure switch
  • Igniter
  • Circuit board

A gas furnace should also be serviced at least once a year, whether it’s in the spring or in the fall. Annual maintenance, including a thorough examination and cleaning of the parts that commonly malfunction, such as air filter, fan motor, pilot light, and heat exchanger, can usually prevent major problems.

One of the most dangerous situations that can happen as a result of not servicing your furnace regularly. When the heat exchanger cracks, your furnace could leak a large quantity of carbon monoxide inside your home. This could be very dangerous to your family’s health and can lead to death. Safety inspection on furnace heat exchanger should be done before each cold season begins by checking for cracks or water leak marks.
