Spring Heat Pump Maintenance Tips Every Homeowner Should Know

When spring rolls in and Vancouver’s chill starts to fade, your heat pump likely needs some maintenance to prepare for the temperature change.

It’s been working double duty all winter—now’s the time to check in before it flips the script and keeps your home cool through summer.

Here are the five most effective maintenance tips that you can do yourself before the summer heat rolls in:

Clear Debris Around Your Outdoor Unit

Winter leaves behind a mess, and your outdoor unit is often surrounded by it. Debris like leaves, branches, mulch, and even forgotten garden tools can block airflow and strain your system. Try to keep at least two feet of clear space around the unit. This helps it run efficiently and prevents overheating. While you're at it, take a look for anything unusual, like nests, trash, or signs of animal activity. Here’s what to look for and remove:

• Leaves, twigs, and grass clippings
• Patio furniture or lawn tools
• Overgrown shrubs or plants

A little cleanup now can help your system run better and last longer through the summer.

Clean or Swap Out Filters

This one is quick but super important. When filters are full of dust or pet hair, your HVAC system has to work harder, which uses more energy and shortens its lifespan. Dirty filters also make indoor air quality worse, especially for those with allergies or asthma. Set a monthly reminder to check your filters, especially if you have pets or live in a dusty area. Hold it up to the light—if you can’t see through it, it’s time for a replacement. Clean filters protect both your system and your health.

Rinse the Outdoor Coil

Your outdoor coils help move heat out of your home, but they get dirty fast. Dirt and pollen build up during spring and fall, making your system less efficient. Gently rinse them with a garden hose, using light water pressure to avoid damaging the fins. If grime is stuck, you can use a soft brush to clean it off. Make sure to shut off power to the unit first. Once everything is rinsed, let it dry before turning the system back on. This quick step can make a big difference in how well your system cools your home.

Double-Check Your Thermostat Settings

With warmer weather on the way, it’s time to check your thermostat. Make sure it’s switched to cooling mode and set to a temperature that matches your comfort level. If your routine has changed—maybe the kids are home for summer or you’re back in the office—adjust the schedule to match. A smart or programmable thermostat can help you save money without sacrificing comfort. Here's what to confirm:

• The mode is set to "cool"
• The temperature schedule fits your current routine

Even small adjustments can make a noticeable impact on comfort and energy savings.

Check Your Indoor Vents

Good airflow inside your home starts with your vents. Walk through each room and make sure nothing is blocking the registers. Furniture, rugs, and even curtains can limit airflow, making some rooms feel stuffy while others stay cool. While you’re at it, give each vent a quick vacuum to remove dust or pet hair. This helps the system push air evenly throughout the house. If certain rooms still feel off, it may be time to have your ductwork inspected for leaks or blockages.

Know When to Call in a Pro

It's good to know the aforementioned maintenance tips, but some things are best left to the experts. If you notice refrigerant leaks or electrical issues, or your system just isn’t cooling like it used to, call a licensed technician right away for an expert opinion.
