Why is Combustion Analysis Important on a Furnace or Boiler
Intro: What is Combustion?
Combustion is the chemical reaction of rapid oxidation started by the correct mixture fuel, oxygen and an ignition source.
Basically, your furnace or boiler needs the correct amount of fuel (oil, natural gas or propane) and oxygen to heat your home to operate safely. Only a combustion analyzer can verify and validate that your heating system is using all the proper amounts safely. Unfortunately many systems, even brand new and recently installed are not properly adjusted.
Think about it for a minute. The equipment was adjusted to manufactures specification at the factory. Then it was shipped by truck and or rail to their distributor. Who sold it to the supply house where it sat until the plumber purchased it. Then it was dropped into their truck and a helper drove it to their shop, then delivered to your home where it likely was "manhandled" into your basement. Do you think all that travel kept it in perfect and ideal manufactures spec? Yeah, I thought so. Keep reading.
One of the first investments I made when hanging out my "shingle" in 2009 was a combustion analyzer. This investment, near the price of our first vehicle - a 2001 Chevy Astro Cargo van purchased on eBay for $2,500 - was simply the best investment made to ensure the safety of the clients who call on us to service and repair their heating equipment.
(Sorry Al, I used the only company analyzer while "doing side jobs" before you fired me for religious purposes - but thank you. Wouldn't be here without you)
Sadly, not many local plumbing, heating or HVAC contractors use the proper tools to confirm a safe system they installed or work on. Why not? Great question. It should be a "code requirement" or a licensing requirement in New York, but municipalities, in my opinion, are revenue focused while portraying, instead, that they are "protecting the constituents" who voted them into office.
(Are you an Plumbing and/or HVAC professional who uses the proper test equipment? Please email me. I'd love to be friends. We are a different breed above the rest)
When we purchased our 2nd and 3rd combustion analyzer the supply house manager bluntly said, "I wish all other contractors made this purchase". (It wasn't a sarcastic remark due to the large revenue sale) Now he asks if I need extra paper for the thermal printer. (We use a lot of thermal paper)

So why is performing a combustion analysis important when inspecting, doing an annual heating tuneup, servicing, repairing and/or commissioning (initial startup) important? Technically it....
- It provides verification and validation of the safety of the appliance before and after servicing, commissioning and/or winterization.
- It allows Calculation of combustion efficiency
- We can monitor the pollution the appliance is producing.
- Verifies conformance with manufactures guidelines.
- Minimizes warranty issues and assure equipment longevity.
That's a mouth full but vital in the operation and performance of the combustion process. In layman's terms....
Combustion Testing Results
A properly tuned heating system saves energy thus lowering your fuel expenses.
An experienced HVAC technician who uses the proper test equipment is not guessing if the system is operating properly. No, you can't tell just by looking at the flame. Only a tech who uses a properly calibrated combustion analyzer can confirm and validate complete combustion with sufficient O2 and minimal or zero CO and CO2.
Testing the combustion process verifies that safely switches, devices and limits are likely not to trip the system preventing a "no heat" call to your plumber or HVAC professional. (Hopefully us)
Confirming the heating appliance is operating properly and to manufactures specifications results in a documented test result which is printed, attached to the appliance and a picture clear on your receipt (Yeah, we are a paperless company. Your detailed 4 page PDF receipt is immediately emailed to you after completion of the service)
Maintains equipment warranty
All heating equipment manufactures require annual testing by a licensed and certified HVAC professional. Why? Not only to prevent bad press (negative reviews) but to maintain your warranty.
Not only will you and your family take comfort in knowing your equipment is operating in a safe manner, so will the HVAC technician when they leave your home knowing he/she left your home with a safe heating appliance. (We all like to sleep sound at night - except with those emergency service calls)
