Additional Ways To Maximize Furnace Control Board Lifespan
This Is Part 3 of a 3 Part Article:
Part 1: Furnace Control Board – Purpose And Functions
Part 2: Furnace Control Board – Power Surge Protection + Surge Protection For The Entire Home
Part 3: Furnace Control Board Lifespan – Additional Ways To Help Maximize Furnace Control Board Lifespan
One Definition Of ‘End Of Life’ For Any Mechanical Item Is:
It has been in operation for at least 2/3 of its expected life (around 15 years for HVAC in DFW).
AND
It needs a repair exceeding 25% of its replacement cost
An identical HVAC System will last longer in one home than in another. This is primarily due to how often & long it runs, and how it’s maintained.
Additional Factors That Reduce Furnace Control Board Lifespan
Frequency & Length Of HVAC System Cycles
Image Source: DreamsTime
- The frequency of cycling (number & length of heating/cooling cycles each day) is the largest factor in any HVAC System’s lifespan. Each cycle creates wear on every component. The more anything gets used, the faster it’s going to wear out.
- The furnace control board lifespan is shortened with increased or prolonged HVAC cycling.
HVAC System Components That Experience Excessive Wear & Tear From Overly Frequent Or Prolonged Cycling
- A gas furnace’s heat-exchanger expands & contracts with each heating cycle. This often causes the heat-exchanger to crack as it gets older. Once cracked, the heat-exchanger or the furnace must be replaced.

SHOWN: Central A/C Outdoor Unit
- For Central A/C & Heat Pumps — the initial start-up is the hardest time on the outdoor unit’s compressor. When the compressor fails– either it, or the entire outdoor unit must be replaced.
Start-up Additional Wear Is Due To 2 Things:
- Because it moves so fast, the outdoor unit’s compressor requires a lot of lubrication. It lacks full lubrication for a few moments after it starts running.
The Amount Of Electricity Required To Start The Compressor Running — Speaks To How Much Wear Occurs At Start-UP (Versus Keeping It Running):
- A 3 ton / 36,000 BTU Central A/C uses 3,000 watts while running — This size cools a 2,000 square foot home in DFW.
- This same A/C requires 9,000 watts at Start-Up. It’s safe to assume that 3 times as much wear occurs at start-up than while it’s running.
It’s much like pressing a car’s accelerator pedal down further to start the car moving — then releasing some of the pedal once the car reaches the desired speed.

Additional Articles Detailing How To Reduce HVAC System Cycling Frequency & Operating Times
These Simple Steps Can Extend Central HVAC System Years Longer
1. Monthly Check Of The Furnace Filter — And Replace When Dirty
Image Source: CanStockPhoto
Shown: Dirty Furnace Filter — Left & New Furnace Filter — Right
The US Dept. Of Energy states: “A Dirty Air Filter Increase Cooling & Heating Costs By Up To 15%.” **
So, It Stands To Reason That A Dirty Air Filter Causes Your HVAC System To Run Up To +15% Longer & Harder — And Wearing It Out 15% Sooner.
** Source: https://www.energy.gov/articles/energy-saver-101-infographic-home-cooling **
- If the filter looks dirty it is — and it needs to be replaced.
- Dirty Filters Cause The HVAC System To Run Longer & Harder Than Necessary. When the filter is dirty — less air can pass through it. This causes the system to run longer to provide the same amount of heating or cooling.
- The longer & harder anything is forced to operate = the shorter its lifespan.
2-A. Annual Spring Central A/C Tune-Up — Outdoor Unit Inspection & Cleaning (as needed)
Image Source: ShutterStock
Image Source: ShutterStock
Shown: Left: Dirty Outdoor Unit Coil – Right: Clean Coil
- Annual Inspection & Cleaning (if needed) Of The Outdoor A/C Unit will identify any failing components or low refrigerant level.
- Furnace control board lifespan is checked during a Spring A/C Tune-Up.
- This provides the opportunity to replace failing components, and avoid a breakdown during peak cooling season.
- A refrigerant recharge helps ensure the a/c is cooling at its maximum ability and efficiency.
- Cleaning the outdoor unit’s coil (as required) has a dramatic effect on both its lifespan & electricity consumption.
The US Dept. Of Energy states “A Dirty A/C Outdoor Unit’s Coil Increases Energy Consumption By Up To +30%!” **
So, If A Dirty Outdoor Unit Causes Your HVAC System To Run Up To +30% Longer & Harder — It’s Wearing Out 30% Sooner.

2-B. Annual Spring Central A/C Tune-Up — Indoor A/C Cooling Coil Inspection & Cleaning (as needed)
Image Source: ShutterStock
Shown: The Indoor Cooling Coil (rounded copper pipe on ends) Is Inside The Furnace — Inches From The Furnace’s Blower-Fan (bright silver).
The indoor cooling coil is inside the furnace, or above the furnace inside the ductwork. It can’t be seen without first removing a panel. Because this coil it what removes humidity, it’s wet during summer. Over time, some dust will pass through the furnace filter, and is likely to get stuck on the indoor cooling coil because it’s wet.
This dust build-up + moisture is all mold needs to start growing on the coil. The coil, being cool, and in a dark place, adds to mold’s ability to grow. The combination of dust build-up and mold growth reduces airflow through the coil AND causes mold-spores to be blown throughout the house when the A/C (and furnace blower) is running.
During a Spring A/C Tune Up — the indoor cooling coil is checked — and cleaning is recommended if needed (an extra charge). This ensures the coil isn’t clogged — and no dangerous mold build-up exists.
In 7.5 years, the indoor cooling-coil has gotten dirty enough to warrant cleaning it. The reduced airflow results in reduced energy efficiency & cooling capacity of up to 5%. **

3. Annual Fall Furnace Tune-Up — Includes Inspection & Cleaning (if needed)
Image Source: DreamsTime
- A gas furnace’s burners create soot while running. Over time, soot builds up on the burners and inside the furnace’s combustion chamber (soot is black).
- While running, a gas furnace draws in a notable amount of air (for combustion) — this causes dust & dirt to accumulate near the burners and inside the combustion chamber.
- Furnace control board lifespan is checked during a Fall Furnace Tune-Up.

(then scroll down a bit)
Furnace control board lifespan will be extended with annual furnace tune-ups. It will also be inspected for early signs of failure.
- Annual Inspection — and cleaning (when needed) extends the life of the furnace and inspects to determine if it’s operating correctly & safely.
- Testing of exhaust-gasses will identify if the heat-exchanger is cracked.
- Inspection of all components will identify if there are any that are nearing failure. This allows for replacement before the furnace quits.
The US Dept. Of Energy states “An Unmaintained Furnace Increases Energy Consumption By Up To +5%!” **
So, It Stands To Reason That A Dirty Outdoor Unit Causes Your HVAC System To Run Up To +5% Longer & Harder — And Wearing It Out 5% Sooner.
Let’s Do The Math:
Reduction In HVAC Efficiency:
- Up To +15% — Dirty Air Filter
- Up To +30% –Unmaintained A/C Outdoor Unit (your furnace blower is running when central A/C runs)
- Up To + 5% — Unmaintained A/C Indoor Cooling Coil
- Up To + 5% — Unmaintained Gas Furnace
Keeping These 4 Items Maintained Can Extend HVAC System Lifespan By Up To +55%
And Lower Cooling & Heating Bills By Up To 55%!
Furnace Control Board — Top Causes Of Early Failure
Image Source: Pexels.com
Furnace control board lifespan: There are numerous reasons why components fail. Some failures are slow and graceful This allows time to identify the failing component and replace it before it quits working and the HVAC System quits. Other failures are rapid and unexpected.
The Most Common Reasons Printed Circuit Boards (Like A Furnace Control Board) Fail:
- Age
- Exposure to; Dust, Water or Moisture, or Excessive Heat (such as due to extended furnace operating-time — due to a dirty filter).
- Over or Under Voltage (power surges & dips)
- Change in the operating environment
- Contamination
- Corrosion: Corrosion occurs when oxygen bonds with metal. Since control boards are largely made of metal — they can easily corrode.
- Chemical fumes: Fumes from certain chemicals are corrosive.
- If a control board (or any printed circuit-board) is in close proximity to these fumes (such as from some cleaning solutions) the fumes can contribute to corrosion. **

Furnace Control Board Failure Can Be Accelerated By Corrosive VOC’s Within Indoor Air
Many products, such as cleaning solutions, give off fumes — known as Volatile Organic Compounds (VOC’s). If the furnace control board is operating in close proximity to VOC fumes, they can contribute to corrosion of the circuit board. We discuss this below.
Because the furnace control board is typically near the blower fan — it’s subjected to enormous amounts of airflow when the furnace runs. A 2.5 ton HVAC System (that size cools & heats a 1,600 square feet DFW home) — moves 1,000 Cubic Feet Of Air Per Minute (CFM). The effects of contaminants within the air are magnified tremendously due to the amount of air movement.

Volatile Organic Compounds (VOC’s) — Their Effect On Your Control Board AND YOU
Knowing that VOC’s can damage a furnace control board — imagine what they can do to your body. We discuss VOC’s in detail below. We also describe a solution.

While Your First Thought Might Be: “There Are No VOC Producing Products In My Home.”
It’s Likely There Are Several — And VOC’s May Be Legally Hidden Within The Term: “Fragrance”.
In the U.S. — manufacturers can legally hide hundreds of synthetic chemicals in the one word: “fragrance” — without revealing what those ingredients are. It’s referred to as a “trade secret”. *6

Many Cleaning Products Emit VOC’s
Volatile Organic Compounds (VOCs) are a large group of chemicals found in many products used to build and maintain our homes. VOCs evaporate easily and quickly at room temperature and are released or “off-gas” into indoor air. VOC’s may or may not have and a scent or odor.
The risk to health from inhaling any chemical depends on:
- How much chemical is in the air.
- How long a person breathes it in.
- How often a person breathes it in.
** Source: https://www.health.state.mn.us/communities/environment/air/toxins/voc.htm
That “New Smell” Is VOC’s Off-Gassing Into The Air
Many new products have a strong odor for a period of time — it’s often known as a “new smell”. This odor is a combination of chemicals used in the manufacture of a new product — and formaldehyde is one of the main chemicals.
Example Of VOC’s Off-Gassing: Many new vinyl shower curtains have a strong smell at first. It’s VOC’s off-gassing / released into the air. As the shower curtain ages, it continues to release fewer & fewer VOC’s until they are mostly gone. Once the VOC’s are gone, the shower curtain no longer smells.
If It Has A Man-Made Scent — The Scent Is emitting VOC’s
NOTE: Natural scents (like directly from a lemon) are not VOC’s.
A survey of selected scented consumer-goods showed the products emitted more than 100 volatile organic compounds (VOCs) — including some that are classified as toxic or hazardous by federal laws. ***
*** Source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3018511/
- Volatile Organic Compounds (VOCs) within indoor air can create a host of health issues. The most common reactions to indoor air VOC’s are; irritation of the eyes, nose, throat, and skin. Also, allergies, asthma, and related respiratory health symptoms can be magnified by the presence of VOC’s.
VOC’s Tests Are Available To Determine The Amount of VOC’s In Your Home’s Indoor Air.

** Source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3018511/ NCBI: National Center for Biotechnology Information. NCBI states: “A survey of selected scented consumer products showed they emitted more than 100 volatile organic compounds (VOCs) — including some classified as toxic or hazardous by federal laws. Some products advertised as “green,” “natural,” or “organic” emitted as many hazardous chemicals as standard ones.”
Natural Versus Man-Made Scents & Fragrances
Image Source: ShutterStock
Natural scents are derived directly from plants & fruits. This is done via processes of boiling and distillation, dissolving in alcohol, or another method of extraction. Natural scents are present in many natural materials such as; rose, vanilla orange rind, pine essence, citronella, and cinnamon essential oils — and are the reason they are so pleasant smelling.
Image Source: ShutterStock
Man-made scents are created in a laboratory by fragrance manufacturers. Synthetic fragrances are scents made of synthetic materials. These scents have either been chemically created — or may have begun as natural scent, and then had man-made compound(s) added. 95% of the chemicals in most commercial fragrances are synthetic compounds derived from petroleum and natural gas — known as petrochemicals. *7
A synthetic fragrance may have no natural ingredients — or some natural scents mixed with petroleum-based products. *** These are typically grouped under the term: “aldehydes” — defined as an organic compound formed by the oxidation of alcohols. In the U.S. — manufacturers can legally hide hundreds of synthetic chemicals in the one word—“fragrance”—without revealing what those ingredients are. It’s referred to as a “trade secret” in the industry. *6
Scents Fall Under These 3 Labels:
- Full synthetics: The fragrance is derived from petroleum by-products.
- Semi-synthetics: Created from some natural, synthetic, or artificially-modified compounds (sometimes all three).
- Natural isolates: A fragrance developed from synthetic and natural byproducts
Some Of The Most Common Chemicals In Synthetic Fragrances Include
- Benzene — a colorless, sweet-smelling chemical derived from; natural gas, crude oil, or coal.
- Benzene is also added to gasoline in concentrations of up to 1.3% — to increase the octane-rating.
- Aldehydes — common aldehydes include formaldehyde and ethanal.
- Formaldehyde is a colorless, flammable, strong-smelling chemical
- Ethanal is colorless, water-soluble liquid that evaporates easily & quickly — it’s used chiefly in the manufacture of perfumes and scents. Ethanal and Ethanol (in gasoline) are not the same.
- Phthalates — used as a perservative in fragrances
- Phthalates are a group of chemicals typically used to make plastics more flexible. These are often called: “plasticizers”.

There Are 2 Types Of UV Light Systems Designed For HVAC Systems
1. For The A/C Indoor Cooling Coil Only (for mold control)
The indoor cooling coil (inside the furnace or ductwork and not visible without removing a panel) is wet during summer (it’s what removes humidity from the air).
Over time, this coil collects some dust (that makes it through the furnace filter). The combination of dust and water is all mold needs to establish and grow.

Al’s Sells & Installs The APCO MAG — UV Light For The Indoor Cooling Coil — To Kill Mold.
2. Whole House Air Purification: A UV Light System That Purifies Moving Air.
Airborne Contaminants Can Be Divided Roughly Into Thirds
Particulates — such as household dust or pollen are removed by air filtration.
Air Filtration Removes Particulates From The Air.
Air filtration doesn’t reduce/eliminate VOC’s & odors — that’s done with Photo Catalytic Oxidation (PCO).
Photo Catalytic Oxidation Removes VOC’s & Odors.
- VOC’s & Odors — Odors generated by Volatile Organic Compounds, or biological odors (like cooking odors). Removed by PCO.
- Biological Contaminants Within The Air — such as Mold & Germs. Removed by PCO.
- PCO doesn’t remove particulates — that’s done with air-filtration.
The APCO UV Light System Purifies Air As It Passes By — With Photo Catalytic Oxidation (PCO)
Click Here To See An Apco Brand Furnace Light For Whole-House Purification: APCO Whole-House UV Light System
VOC’s Removal
PhotoCatalytic Oxidation (PCO) occurs when UV light rays shine on a Titanium Oxide coated surface.
This process creates highly reactive electrons that aggressively combine with indoor-air contaminants such as; VOC’s, Bacteria, Mold & Fungus.
The PCO process disintegrates these indoor-air contaminants, leaving only water-vapor & carbon dioxide behind.
Odor Control
APCO eliminates odors — by transforming them into water vapor & carbon dioxide.
The UV-C light in APCO UV Light System can keep the indoor AC coil free of mold (if it can be installed quite near the indoor cooling-coil). Mold clogs the indoor cooling-coil and disperses mold-spores when the blower fan is running. . This shortens HVAC System lifespan + wastes energy. UV-C light kills mold — and prevents new mold growth.
Germ-Killing
For over a century scientists have known about the germ-killing properties of UV-C light. Because UV-C’s light-frequency is filtered out by the Earth’s atmosphere — microorganisms don’t have defenses against UV-C light. UV-C light scrambles the DNA of germs — preventing germs from reproducing.
