Why Heat Pump Coil Cleaning is Crucial for Performance and Longevity

Have you noticed your home in Duncan, BC, not heating or cooling as efficiently as it used to? Your energy bills have quietly crept up, or your heat pump is running longer than it should. We see this all the time, and one of the most overlooked reasons is a simple one: dirty coils. At Capital City Power Vacuum, we’ve helped countless homeowners with heat pump coil cleaning, and let us tell you—it makes a difference.

Let’s talk about why coil cleaning matters, what happens if it’s ignored, and how it impacts your heat pump’s performance, lifespan, and your wallet.

The Role of Coils in Your Heat Pump

Before we get into the dirt (literally), it’s helpful to understand what the coils in your heat pump do.

Your heat pump has two main types of coils:

• Evaporator Coil (Indoor Coil): Absorbs heat from inside your home in the cooling season.
• Condenser Coil (Outdoor Coil): Releases heat outdoors during cooling, and absorbs heat during heating.

When these coils get covered in dust, debris, or even mold, the heat transfer process is disrupted. It’s like trying to breathe through a scarf soaked in water—your system just can’t do its job correctly.

What Happens When You Skip Coil Cleaning?

We often hear folks say, “My heat pump seems fine—why clean the coils?”
You might not notice problems right away. But over time, dirty coils lead to:

• Reduced Efficiency: Your system has to work harder to reach the same temperature.
• Higher Power Bills: The longer it runs, the more energy it uses.
• Poor Heating or Cooling: Uneven temperatures and longer run times.
• Increased Wear and Tear: Motors and fans get overworked.
• Shorter System Lifespan: Components wear out faster, leading to costly repairs or early replacement.

Simply put, cleaning your heat pump coils isn’t just maintenance—it’s protection for your investment.

Signs Your Heat Pump Needs a Coil Cleaning

Is your system due for a clean? Here are a few signs we look out for:

• Airflow feels weaker than usual
• The unit is running constantly or cycling frequently
• Dust build-up on or around the outdoor unit
• Musty smells are coming from your vents
• Rising electricity bills with no other explanation
• Ice forming on the outdoor coil, especially in winter

If any of these sound familiar, it’s time to reach out to a heat pump coil cleaner.

Duncan BC’s Local Climate Adds to the Problem

Living in Duncan, BC, means we deal with a fair bit of coastal moisture, tree pollen, and airborne particles year-round. That environment speeds up the buildup of grime on outdoor coils. Even leaves, grass clippings, and pet hair can sneak in and start to clog things up.

If your outdoor unit is near a garden, driveway, or tree, it’s even more likely to get dirty. We’ve cleaned coils where the entire bottom half was blocked entirely—no wonder the system was struggling.

How Coil Cleaning Works (And Why It’s Not a DIY Job)

We often get asked: “Can I just hose it down myself?”
While the thought is understandable, coil cleaning takes more than a garden hose.

Here’s what we do during a professional heat pump coil cleaning:

Step	What Happens
1. Inspection	We check the coils for dirt, damage, and any warning signs
2. Safe Access	Panels are adequately removed to reach coils without damage
3. Surface Cleaning	Debris and buildup are brushed and vacuumed off carefully
4. Coil Cleaner Application	We apply eco-safe, non-corrosive cleaner to dissolve grime
5. Rinse and Dry	Everything is rinsed and dried, with no risk to wiring or parts
6. Final Check	The system is reassembled, tested, and the airflow is measured

You need the right tools, the right cleaner, and the experience to know what to look for. Trust us, we’ve seen DIY attempts that ended with bent fins, soaked electrical parts, or worse—a broken unit.

How Often Should You Clean the Coils?

In Duncan BC, we recommend cleaning the coils at least once a year—ideally before peak heating or cooling seasons begin. For homes surrounded by trees or near high-traffic roads, twice a year might be a better option.

If you’ve just moved into a new home or can’t remember the last time it was done, it’s a good idea to get things checked sooner rather than later.

The Long-Term Payoff of Clean Coils

Regular cleaning of your heat pump may not feel glamorous, but it pays off in ways that matter:

• Energy Savings: Cleaner coils mean your system doesn’t have to work overtime.
• Fewer Repairs: Less strain equals fewer breakdowns.
• Better Comfort: More consistent temperatures throughout your home.
• Longer Equipment Life: Delay replacement and protect your investment.
• Cleaner Air: Less dust circulating through your system means cleaner indoor air.

When you add it all up, coil cleaning isn’t just maintenance—it’s money in your pocket.
