What to check after heat pump installation
The work is not quite finished when the installer packs up. The first days and weeks after a heat pump installation are when you confirm everything is running the way it should, before small issues become bigger ones.
Most quality installs perform beautifully, but a quick post-installation review protects your investment. Checking airflow, noise, drainage, and paperwork now means fewer surprises during our first cold Fraser Valley snap or the first warm week of summer.
This guide covers what HeatLand recommends you verify after any installation. If anything on this list looks or sounds off, it is worth a call. We are family-run, licensed, and have served Metro Vancouver since 1999, and we would rather fix a small thing early than have you live with it.
Test Both Heating and Cooling Modes
A heat pump both heats and cools, so confirm both modes actually work before you sign off. Set the thermostat to heating and verify warm air arrives at the registers or indoor heads within a few minutes. Then switch to cooling and confirm cold air. Because our summers and winters are months apart, it is easy to discover a problem in the off-season when it is inconvenient to address.
Walk through each room and feel for reasonably even temperatures. Large cold or hot spots can point to airflow balancing issues or duct problems. Also confirm your backup or auxiliary heat engages correctly if your system has it, since that is what carries you through the coldest mornings.
Ask your installer to demonstrate both modes during the walkthrough, and note how long each takes to respond. If one mode does not work or a room stays uncomfortable, flag it while the install is fresh.
Inspect the Outdoor Unit and Drainage
Step outside and look at the condenser. It should sit level on a solid pad or stand, with clearance from walls, fences, and plants for proper airflow. In areas that see snow, it should be raised enough to stay clear of accumulation. A tilted or wobbling unit can cause noise and drainage problems over time.
Check that refrigerant lines are neatly run and insulated, and that any wall penetrations are sealed against water and pests. Inside, confirm the condensate drain is carrying moisture away without pooling, especially in cooling mode. Water stains, dripping, or a musty smell near the indoor unit deserve attention.
Safety note: if you ever notice water pooling near electrical components, a persistent burning smell, or ice building up on the indoor coil, turn the system off and call a licensed technician. Do not keep running a unit that is leaking water onto wiring.
Listen for Noise and Check Vibration
A properly installed heat pump is fairly quiet. During the walkthrough and over the first few days, listen for rattles, buzzing, grinding, or loud vibration from either the indoor or outdoor unit. A steady low hum is normal, but sharp or irregular noises can indicate loose panels, mounting problems, or a component that needs attention.
Vibration transmitted into the house often means the outdoor unit needs better isolation pads or the mounting needs adjustment. This is easy to correct early and annoying to live with if ignored. Pay attention near bedrooms, where even modest noise matters at night.
Compare what you hear to what the installer described. If the sound changed after the crew left, or a new noise appears within the first weeks, make a note and report it. Catching mounting and balance issues early prevents premature wear on fans and compressors.
Confirm Paperwork, Thermostat, and Maintenance
The final check is administrative but important. Make sure you received copies of permits, the manufacturer warranty registration, and any rebate documentation. Warranty registration often must be completed within a set window, so confirm it is done. Keep these records together for future service and resale.
Have the installer walk you through the thermostat, including scheduling, heating and cooling setpoints, and any special heat pump modes. Learn where the air filter is, what size it takes, and how often to change it, since a clogged filter is a leading cause of early performance complaints. Ask how to clear the outdoor unit of leaves and snow safely.
Finally, ask about a maintenance plan. Annual professional service keeps efficiency up and protects your warranty. HeatLand offers maintenance plans and is available for emergency service if anything goes wrong.

| Paperwork | Permits and warranty in hand | Missing documents |
Frequently Asked Questions
How soon should I test my new heat pump in both modes?
Test both heating and cooling during the installer’s walkthrough, or within the first day. Because heating and cooling seasons are months apart in Metro Vancouver, waiting until you actually need one mode risks discovering a problem at the worst time. Verifying both while the install is fresh makes any warranty follow-up much simpler.
Is some noise from a heat pump normal?
Yes. A steady low hum from the outdoor unit and gentle airflow indoors are normal. What is not normal is rattling, buzzing, grinding, or strong vibration transmitted into the house. Those usually point to loose panels or mounting issues that are easy to correct early. Report any new or sharp noises to your installer.
What paperwork should I have after installation?
You should receive copies of any permits, manufacturer warranty registration, the equipment manual, and any rebate documentation. Warranty registration often has a deadline, so confirm it is completed. Keep everything together, as you will need it for future service, rebate follow-up, and when you eventually sell your home.
When should my first maintenance visit be?
Most manufacturers recommend annual professional maintenance, so plan your first service roughly a year after installation, or per your warranty terms. Between visits, change or clean the filter regularly and keep the outdoor unit clear of debris and snow. A maintenance plan makes it easy to stay on schedule and protect efficiency.
