Ever noticed how your car runs smoother after a service? Or how your shower has better pressure after you clean out the limescale? Your heat pump works the same way—when it’s clean and well-maintained, it heats (and cools) your home faster, cheaper, and more efficiently. But when it’s neglected? That’s when things start going downhill—higher power bills, weak airflow, and the dreaded musty smell no one wants in their living room.

At Air Conditioning Group, we see it all the time—people assume their heat pump is fine until it suddenly isn’t. And by then, it’s usually working twice as hard and costing twice as much to do half the job. So, before winter fully sets in, let’s talk about how to keep your heat pump in top shape, saving you money, stress, and chilly nights.

 

Why Heat Pumps Need Regular TLC (And What Happens If You Ignore Them)

Your heat pump is a workhorse, running nearly all year round to keep your home comfortable. But that means it collects dust, dirt, and moisture, which—if left unchecked—causes all sorts of problems:

  • Clogged filters force your system to work harder, increasing your electricity bill.
  • Blocked airflow means it takes longer to heat or cool your home, making it inefficient.
  • Mould and bacteria can build up, affecting air quality and creating unpleasant smells.
  • Dirty coils reduce the system’s ability to transfer heat effectively, meaning you get less warmth for more energy.

And the worst part? You probably won’t notice the problem until it’s too late—when winter hits and your heat pump just isn’t cutting it.

 

How to Clean Your Heat Pump The Right Way

The good news? Some basic heat pump maintenance is easy to do yourself—but there are also some jobs best left to the pros. Here’s what you should be doing regularly:

 

What You Can DIY

  • Clean the Filters: Your filters trap dust and allergens, stopping them from circulating around your home. If they’re clogged, your heat pump is struggling. Simply remove them and give them a gentle vacuum or rinse under warm water. Do this every 2-3 months (more often if you have pets).
  • Wipe Down the Indoor Unit: Dust and grime collect on the surface of your heat pump, especially around the vents. A quick wipe-down helps keep airflow unobstructed.
  • Check the Outdoor Unit: The external component of your heat pump needs clear space to ‘breathe’. If it’s blocked by leaves, dirt, or cobwebs, it won’t perform properly. Give it a check every few months and clear any debris.

 

What You Should Leave to the Experts

While regular cleaning keeps things running smoothly, some issues require professional servicing. Here’s what we handle during a full heat pump service:

  • Deep cleaning of the coils (which are critical for efficient heating and cooling).
  • Flushing the drainage system to prevent leaks and mould build-up.
  • Checking for refrigerant leaks (which can severely impact performance).
  • Inspecting the electrical components to ensure everything’s working safely and efficiently.

Think of it like this: Cleaning your filters is like brushing your teeth, but getting a professional service is like visiting the dentist. Both are necessary—one just stops the big problems before they start.

 

The Cost of Doing Nothing (It’s More Than You Think)

Ignoring your heat pump might not seem like a big deal—until you see the numbers.

A dirty, clogged heat pump can use up to 25% more energy than a well-maintained one. That means your monthly power bill is higher than it needs to be, and you’re paying extra for a system that’s underperforming.

And if you’re thinking, “I’ll deal with it later”, just remember: a neglected heat pump has a shorter lifespan. Replacing an entire unit costs thousands—while a service costs a fraction of that and extends the life of your system by years.

 

Is Your Heat Pump Trying to Tell You Something? (Signs You Need a Service ASAP)

Not sure if your heat pump is overdue for some love? Here are some red flags to watch out for:

  • Weak airflow (if it feels like your heat pump is whispering rather than working, there’s a problem).
  • Unusual noises (a well-maintained system shouldn’t be rattling, whistling, or groaning).
  • Higher energy bills (if you’re paying more but feeling less, your heat pump is working too hard).
  • Musty or damp smells (this usually means mould or bacteria have taken up residence inside your unit).
  • Inconsistent temperatures (if your heat pump can’t decide whether it’s heating or just making vague promises, it’s time for a check-up).

If any of these sound familiar, your heat pump isn’t running efficiently—and the longer you wait, the worse (and more expensive) it gets.

 

How Often Should You Get Your Heat Pump Serviced?

Here’s the golden rule:

  • At least once a year if you use your heat pump regularly.
  • Twice a year if it’s your primary heating and cooling system (especially if you run it through summer and winter).

The best time? Right before winter or summer—so you’re not left scrambling when you need it most.
