During the hot summer days, your heat pump probably worked hard to keep your home at a comfortable temperature. But as late August brings cooler nights, your heat pump will soon take on a different role: after cooling your home for several months, it will have to start heating it.
This transition period is therefore an excellent time to check its condition and make sure it’s ready when temperatures really begin to drop.
Here are a few simple checks that can make all the difference.
1. Start With the Filters
This is probably the simplest maintenance task… and one of the most commonly overlooked.
After a summer of regular use, filters may have accumulated dust, pet hair and other particles. When they become clogged, air cannot circulate as easily, forcing the heat pump to work harder to reach the desired temperature.
Depending on the model, filters can either be cleaned or replaced. Take advantage of the end of summer to inspect them and consult the manufacturer’s recommendations regarding maintenance.
A clean filter not only contributes to the efficiency of your system but also helps improve air circulation throughout your home.
2. Take a Look at the Outdoor Unit
The outdoor unit has also spent several months exposed to the elements.
Leaves, grass, dust and debris can accumulate around the unit and interfere with proper airflow. With fall approaching, fallen leaves will soon add to the problem.
Make sure the area surrounding the unit is clear and that nothing is blocking the air intake or exhaust.
A word of caution: while homeowners can perform light cleaning around the outdoor unit, dismantling the equipment or cleaning its internal components should be left to a qualified technician.
3. Listen to Your Heat Pump
You’re probably familiar with the normal sounds your heat pump makes. That’s precisely why you may quickly notice when something sounds different.
New vibrations, rattling, whistling or mechanical noises may indicate that a component should be inspected.
The same applies if the outdoor unit seems to run much longer than it used to or if it constantly starts and stops.
A small change in behaviour doesn’t necessarily mean that a major repair is required. But it’s better to have it checked now than during the first real cold spell.
4. Test the Heating Mode
Why wait until October to discover that something isn’t working properly?
On a cool morning, switch your heat pump to heating mode and let it run for a while. Check whether it is producing warm air properly and whether the room temperature increases normally.
The goal, of course, isn’t to turn your living room into a sauna in August! It’s simply to make sure the transition from cooling to heating is working as it should.
If the air remains cool, if the system takes an unusually long time to heat the room or if you notice a significant difference compared with previous years, an inspection may be worthwhile.
5. Don’t Forget About Water Drainage
When operating in cooling mode, a heat pump removes some of the humidity from the indoor air. That condensation needs to drain properly.
A partially blocked drain can lead to water leaks, unpleasant odours or moisture around the indoor unit.
After a full season of air conditioning, it’s a good idea to check for any unusual signs of water or moisture around the system.
6. Is Your Heat Pump Performing as Well as It Used To?
A heat pump can continue to operate even while gradually losing efficiency.
Ask yourself a few questions: Did it have more difficulty cooling your home this summer? Did you have to lower the thermostat more than usual to achieve the same level of comfort? Does it run longer? Has it become noisier?
If your heat pump is several years old and its performance seems to be declining, late summer is a good time to have its condition assessed.
That doesn’t automatically mean it needs to be replaced. In some cases, maintenance or a repair may be all that’s needed to restore optimal performance.
7. Why Schedule Maintenance Before the Cold Season?
Because the best time to discover a heating problem is when you don’t actually need the heat yet.
Having your heat pump checked before colder weather arrives can help identify potential issues, allow time to schedule repairs if necessary and reduce the risk of a breakdown when the system becomes essential.
Proper maintenance can also help maintain energy efficiency and extend the lifespan of your equipment.
Late Summer: The Right Time to Think Ahead
In the Laurentians, beautiful summer weather can continue for several more weeks, but cooler nights quickly remind us that fall is approaching.
Your heat pump has just completed a good part of its summer workload. Before asking it to take on its next mission—heating your home—give it a little attention.
Not sure whether your heat pump is operating as efficiently as it should? The Pétrole Pagé team can assess its condition and advise you on the maintenance, repair or replacement of your system.
It’s much better to take care of it while the weather is still mild… rather than waiting for your heat pump to decide it’s time for a vacation!
