When to Clean Your Heater Coils?

We recommend a yearly inspection and cleaning, typically in the fall, before the onset of the cooler months when you’ll rely on your heating system the most. However, if you notice any signs of decreased performance, it might be time for a check-up.

The Cleaning Process:

  1. Safety First: Always turn off the power to your HVAC system to prevent any electrical hazards. This is non-negotiable for the safety and protection of your system.
  2. Access the Coils: Remove the access panel with the appropriate tools — this is typically a simple task, but one that must be done with care to avoid any damage.
  3. Initial Inspection: Once you have a clear view, inspect the coils for any noticeable build-up or damage. This will inform the intensity of the cleaning needed.
  4. Vacuuming: A soft brush attachment on your vacuum cleaner can be your best friend here. It’s gentle yet effective at removing loose debris without harming the delicate coils.
  5. Apply Cleaner: Utilize a commercial coil cleaner suitable for your system. These specialized solutions are formulated to break down the dirt without corroding the coils.
  6. Rinse (If Required): Depending on the cleaner used, you may need to rinse the coils. If you’re cleaning evaporator coils located indoors, you’ll want to use a no-rinse foam that dissolves and drains away.
  7. Straighten Fins: If during your inspection you notice any bent fins, carefully straighten them with a fin comb. This ensures that air can flow freely, optimizing your system’s performance.
  8. Clear Drainage: Prevent water damage by checking the drainage system associated with your heater coils, making sure it’s free from obstructions.
  9. Final Checks: After the coils are clean, take a moment to inspect them. Ensure all debris and cleaner have been removed and there are no signs of damage.
  10. System Restart: Once everything is back in place, restore the power and watch your system start. You should notice improved efficiency and air quality.

Remember: If you’re unsure at any point, it’s prudent to call in a professional. The AC Therapist is always here to assist, ensuring the job is done safely and effectively.

By maintaining your heater coils with The AC Therapist’s approach, you can rest easy knowing your system is in prime condition, providing you with warmth and peace of mind.

Why Clean Heater Coils?

Heater coils, over time, collect dust and other particulates that can impede performance, reduce efficiency, and even pose health risks. Regular cleaning prevents these issues and extends the life of your HVAC system.

1. Overheating: A Prelude to Potential Disaster

Understanding Overheating

Overheating in the HVAC world isn’t just about discomfort; it’s a precursor to potential disaster. Heater coils, when free of dust, allow for seamless heat transfer. This equilibrium keeps the system running smoothly. But introduce a layer of dirt, and you’re effectively insulating these coils, causing them to retain excessive heat.

This retained heat leads to an array of problems. The coils themselves can reach temperatures far beyond their design limits, and the excessive heat can cause expansion and warping. This isn’t just a matter of system efficiency; it’s a safety concern. These structural changes can result in cracks and exposure to electrical components, increasing the risk of electrical fires.

The Risks at Stake

These are not isolated issues. The problem of overheating heater coils can cascade, causing nearby plastic components to melt and release harmful fumes, potentially igniting in the presence of enough heat. Moreover, accumulated dust and debris around the coils can also catch fire, resulting in a dangerous blaze that can travel quickly through ductwork.

Through my years of experience, I’ve learned that preventative maintenance is key. Ensuring that your heater coils are cleaned regularly is not just about prolonging the life of your system, it’s about safeguarding your home.

2. Electrical Short Circuits: Sparking Danger

The Efficiency-Electricity Link

An HVAC system’s electrical efficiency is intrinsically linked to the cleanliness of its components, particularly the heater coils. When dirt accumulates, resistance increases, which in turn elevates the electrical demand of the system. This can cause the wiring to overheat and circuitry to wear down prematurely, setting the stage for electrical shorts a dangerous spark awaiting a fuel source.

Understanding the Domino Effect

A short circuit can be the first domino in a chain reaction leading to fire. In a dust-laden system, sparks can find ample fuel to ignite, and from there, a fire can spread unseen behind walls and ceilings, making it a formidable challenge to detect and extinguish.

In our routine maintenance checks, we often find and repair minor issues like worn insulation or a loose connection, small fixes that prevent big disasters.

3. Impaired Safety Mechanisms

Relying on Integral Safety Systems

HVAC units come equipped with numerous safety mechanisms, such as high-limit switches and circuit breakers. These systems are meant to prevent overheating and electrical overload. However, when heater coils are caked in grime, these critical safety features can malfunction, not because they are faulty, but because they are dirty.

The Consequence of Compromised Protection

Dirty heater coils can disguise the true temperatures within your system, fooling safety switches and sensors. This means that your system might continue to operate in unsafe conditions, leading to increased risks of fire. It is crucial during our service visits to not only clean these coils but also test and ensure all safety mechanisms are functioning properly.

4. Increased Strain on HVAC Components

Dust: More Than Just an Allergen

Air quality within a home is often discussed in terms of comfort and health, with dust being a common allergen that can exacerbate conditions like asthma and allergies. However, the role of dust in HVAC systems goes beyond mere discomfort. In the context of heater coils, dust can act as a catalyst for combustion, significantly raising the risk of fire within the unit.

When heater coils become dirty, their efficiency in heating and air transfer is diminished, but another, more insidious problem arises. The accumulated dust particles on the coils and within the HVAC system can be composed of not only benign lint and pollen but also highly combustible materials like paper fibers, pet dander, and even traces of volatile chemicals from household cleaning products.

A Flammable Mixture

This mix of particulates poses a greater danger than just poor air quality, it creates a flammable mixture. When dust collects on heating elements like the heater coils, it’s not just an insulator that leads to overheating; it’s potential fuel. With enough heat, this fuel can ignite, causing what might start as a small electrical fire to become a full-blown blaze that can rapidly spread throughout a property via the HVAC system.

Furthermore, as the heater coils attempt to do their job, they can end up pushing this combustible dust into the air, allowing it to settle on surfaces throughout the home. This not only degrades the air quality further but spreads the potential for fire beyond the HVAC system itself. Even a small spark, which might be inconsequential in a clean environment, can have disastrous consequences in the presence of such a dusty atmosphere.

5. Reduced Air Quality: A Catalyst for Combustion

The Hidden Danger of Dust

We often think of dust in terms of indoor air quality and health, but its implications reach further. Dust on heater coils isn’t just an allergen; it’s a potential fire starter. Mixed with other household particulates, it becomes a combustible concoction that can ignite under the right conditions.

Combustion Beyond Air Quality

The risk extends beyond the HVAC unit. Dust pushed into the air by the heating process settles around your home, carrying the potential for fire with it. A small spark, in a clean environment, would be harmless, but in a dusty room, it can be disastrous.
