The Furnace is the heart of your heating and air conditioning system. It is usually located in your Attic, Hall Closet, or Garage, depending on how your house was built. The Furnace circulates the air in your house through the duct system over and over again until the air in your home or business is as warm as you want it to be by setting the thermostat. The Furnace is also loaded with different components and safety devices to protect you and your home.
Every time you set your thermostat to heat your home, a series of safety checks are performed, without you even knowing it, before the gas valve opens and allows the fuel to ignite and heat your home. After initial ignition, there are more safety checks to make sure the fuel has ignited properly, and additional safety devices to make sure the air is circulating through the furnace so it does not overheat. All of these safety checks are monitored by the Primary Circuit Control Module, also known as “the brain” of the furnace. Should any of the safety checks fail, “The Brain” turns off the furnace, puts the furnace in to Lockout mode, and prevents your home or business from heating. That’s when we get calls from panicked and freezing clients to come out for an emergency service call and repair the heating system.
Cause for Concern!
Two parts of the heating system which are the cause for most concern are the Exhaust System, and the Heat Exchanger. These two parts of your home comfort system are the ones that deal with preventing Carbon Monoxide from entering your home from the furnace. ARS Comfort Solutions, Inc. is the ONLY company in the Bay Area which is Certified for Combustion and Carbon Monoxide Analysis. Why would you trust your safety to anyone else?
The exhaust system is responsible for removing all of the combustion by-products, such as carbon monoxide, from the furnace and expelling those by-products to the outside. Even though the furnace goes through many safety checks to make sure that the components are working, there are three safety tests which need to be performed during a tune-up or a repair call by a properly trained and certified technician. These three tests should be performed during every furnace tune-up, and every repair call, to assist in making sure you are safe.
There is no way to tell if the exhaust system is properly working and venting the combustion by-products to the outside without a visual safety check. During this inspection, all exhaust vent connections are inspected, the exhaust system if inspected for rust, damage, and acid residue, which indicates improper combustion.
A Draft Test performed by a properly trained and certified technician makes sure that the exhaust system of your furnace is operating properly, is not blocked, and is not being affected by other items such as building pressures, wind, or partially performing combustion motor. This test is vital for the exhaust system of your furnace.
Carbon Monoxide Test
A Carbon Monoxide Test performed by a properly trained and certified technician will let us know if the carbon monoxide levels in the exhaust system are within safe limits, and will let us know if the combustion process is operating at its maximum efficiency. Maximizing the combustion efficiency of your furnace can save you thousands of dollars over the lifetime of your furnace.
The heat exchanger separates the combustion by-products such as Carbon Monoxide, from the air in your house. The heat exchanger where the gas in your furnace burns, and the combustion process takes place. As the colder air from your home circulates through the furnace, it absorbs the heat off of the heat exchanger and warms the air in your home.
The heat exchanger is made of metal and sealed from the indoor air that you breathe. During normal operation, this metal heats and cools, expands and contract, thousands of times during the life of the furnace. The hope is that the heat exchanger will never crack or rot, The reality is most heat exchangers do crack and rot, and you never know it until someone in the home or building gets sick from Carbon Monoxide Poisoning, or even worse, Dies. The Good News is simple steps can be taken to help prevent you from Carbon Monoxide Poisoning and Dying from Carbon Monoxide Poisoning.
Get a yearly tune-up from a company who includes Visual, Draft, Carbon Monoxide, and Combustion Testing in their tune-up program and who is certified in Carbon Monoxide and Combustion Analysis, such as ARS Comfort Solutions, Inc.
Purchase a Low Level Carbon Monoxide Monitor and Alarm such as the NSI 3000.*
*The NSI 3000 is not sold in stores, monitors Carbon Monoxide at lower levels than store bought CO detectors, and Alarms when CO levels are becoming unsafe. Most store bought CO detectors only alarm at high levels and after a long period of time so the building occupant will be sick or dead already.
