What to Expect When You’re Expecting… a Heat Pump
A Homeowner’s Guide to Heat Pump “Leaks” and Other Normal Behaviours
Congratulations — you’re expecting! A heat pump, that is.
Whether your new heat pump just arrived or you’re still in the planning stages, there are a few things no one tells you upfront — like the fact that it might start “leaking” water. But before you panic or call for help, take a deep breath. You’re not alone, and this is completely normal.
This fall and winter, especially in a city like Vancouver where the weather shifts dramatically, many new (and seasoned) heat pump owners find themselves surprised by the sudden appearance of water coming from their outdoor unit. Think of this blog as your “What to Expect When You’re Expecting…a Heat Pump” guide, focused on one key topic: condensate.
📘 Chapter One: “Wait, Is My Heat Pump Leaking?”
Let’s get this out of the way: If you see water coming from your heat pump this time of year, it probably isn’t leaking — it’s sweating.
Just like babies drool and teens get moody, heat pumps produce condensate as a normal part of operation as the seasons change and the air becomes denser. When in heating mode, the outdoor unit draws heat from the air, and in doing so, moisture in that air condenses on the outdoor coil. That water has to go somewhere — so it drips off.
In Vancouver’s damp fall and early winter, this can look like a small puddle or a steady drip. It’s not a problem. It’s just your heat pump doing what it’s supposed to do.
💡 Pro Tip for “Nursery” Planning
Just like you’d carefully plan a nursery for a new arrival, you’ll want to be thoughtful about where you install your heat pump. One key reason? Condensate drainage.
Here’s what to consider:
- Avoid placing the outdoor unit near walkways or stairs — in frosty weather, that condensate can be slippery.
- Don’t install it above or beside storage sheds, susceptible tools, or areas where water could damage items.
- Make sure there’s proper drainage below and around the unit. Water should flow away from your foundation, not toward it.
A little foresight can save a lot of headaches later — and help your heat pump thrive in its new “home.”
🚨 Chapter Two: When to Call the Doctor (aka Your HVAC Tech)
While most heat pump “leaks” are just harmless condensate, there are some symptoms that are worth a check-up.
Here are the top 3 signs something might not be quite right:
1. It’s Constant or Out of Season
If water is coming from your heat pump year-round, even in warm summer temps, or when the system is off, it might not be condensate — it could be a clogged drain, internal leak, or refrigerant issue.
2. The Water Looks or Smells Weird
Condensate is typically clear and odourless. If the liquid is:
- Brown, rusty, or oily
- Has a strong smell
- Seems to be mixed with sludge or debris
…it’s time to book a service visit.
3. It’s Ice, Not Water
If the unit isn’t dripping, but instead forming ice on or around the outdoor coil, something might be off with the defrost cycle or airflow. Ice buildup is a red flag — and it’s easier (and cheaper) to address early.
👶 Chapter Three: You’re Not Alone
Every homeowner with a new heat pump goes through this learning curve. It’s normal to be concerned when water appears unexpectedly — but understanding what to expect can give you peace of mind.
If you’re ever unsure, call us. Think of it like a check-up during a pregnancy — it might just be routine, but it offers reassurance and helps catch issues early.
🛠️ Final Thoughts: Embrace the Drip
In summary:
- Water coming from your heat pump in fall is usually just condensate
- It’s normal and temporary
- Good planning during installation can prevent mess and hazards
- Know the signs of an issue, but don’t panic at the first drop
