Change the filters regularly. It’s a quick fix that can save you a lot of hassle later on. When filters get clogged, air flow suffers, which forces the system to work harder. Over time, that wears it down. Aim for at least once every three months, but if you have pets or live in a dustier area, you may want to check them even more often.
Another thing to consider is the refrigerant levels. Low refrigerant can prevent the unit from cooling effectively. If you notice it taking longer to reach your desired temperature or if the system starts making unusual noises, it might be a sign that the refrigerant needs topping up. You’ll need a professional for this–don’t try to handle it yourself. A technician can inspect for leaks and ensure everything is working correctly.
It’s easy to forget about the outdoor unit, but this part of the system needs attention, too. Keep the area around it clear of debris, like leaves or branches, which can block airflow. If the coils get dirty, the whole system could lose efficiency, and it could even freeze up. Just a quick seasonal clean-up can go a long way in keeping things running smoothly.
Lastly, give the system a once-over before the heat hits. Turn it on ahead of time to make sure it’s cooling properly. You don’t want to discover a problem in the middle of a heatwave. Taking a little time for these simple checks now can save you money and headaches later.
Cleaning and Replacing Filters for Optimal Performance
Filters should be checked regularly to keep the system running smoothly. Every 1–3 months is a good rule of thumb, depending on usage. If you have pets or allergies, cleaning or replacing the filter more often can make a big difference. A clogged filter restricts airflow, which can lead to reduced efficiency, and in some cases, damage to the unit.
To clean or replace a filter, first turn off the unit. Carefully remove the filter from its slot and inspect it. If the filter is washable, rinse it with warm water and let it dry completely before reinstalling. For non-washable filters, replacement is often the better option. These can usually be found at hardware stores, and choosing the right size and type is key for good airflow.
Filters come in different MERV ratings, which indicate how fine the particles they trap are. Higher MERV ratings mean better filtration, but sometimes they can restrict airflow if your system is not designed for them. It’s a good idea to stick with a filter that matches your system’s specifications. It may seem like overkill to obsess over these details, but it really does help with long-term efficiency.
Don’t forget that a filter can look clean but still need replacement. Dust and dirt build up over time and may not be visible at first glance. If airflow feels weak or there’s a noticeable change in the system’s performance, it’s time to replace the filter, regardless of its appearance.
It’s a small task, but cleaning or replacing filters regularly can extend the life of your unit and keep your space comfortable. It’s one of those things you don’t want to put off, especially when the summer heat is just around the corner!
Checking and Sealing Ductwork to Prevent Air Leaks

Inspect the ductwork at least once a year. Look for any visible signs of wear, holes, or gaps where air could escape. Pay special attention to joints and seams–these areas are most prone to leaks. If you notice any issues, it’s often a good idea to seal them with mastic or specialized tape. I know it sounds simple, but this small step can really improve efficiency by preventing conditioned air from escaping into the attic or walls.
If you can, use a smoke pencil or incense stick to test for air leaks. Hold the smoke near the duct connections and see if the smoke is drawn toward any gaps. It’s not foolproof, but it’s an easy and quick test you can do yourself. Just be careful not to overdo it with the incense–no one wants their home smelling like a burning stick of incense, right?
Sealing ducts also helps control humidity levels, which can be an issue during Calgary’s summer months. If your ducts aren’t sealed properly, moisture could enter and lead to mold or mildew growth, especially in areas like basements or attics. Sealing also makes it less likely for dust and debris to get sucked in, keeping your indoor air cleaner.
For harder-to-reach spots, consider using a professional service. Some areas may be tricky to seal properly without the right tools or knowledge. And while DIY is great, there are times when it’s worth bringing in an expert to make sure everything is sealed tight.
Don’t forget to inspect the insulation around the ducts as well. If it’s damaged or missing, it could cause the ducts to lose heat in the winter, making the system work harder. Replace or add insulation where necessary–especially in areas where ducts run through unconditioned spaces.
Scheduling Regular Professional Maintenance for Longevity
It’s smart to book maintenance at least once a year with a professional. The best time? Early spring, before the heat sets in. This way, you’ll ensure everything is running smoothly ahead of the warmer months. Skipping this can lead to breakdowns when you need your system the most–trust me, it’s better to avoid the hassle.
During a service check, the technician will go over several things you might not even think about, like cleaning coils, checking refrigerant levels, and ensuring airflow is optimal. These small adjustments can add years to the life of your unit, cutting down on the likelihood of costly repairs. It also helps the system run more quietly, which is always a win, right?
It’s easy to overlook, but systems work hard, especially during hot spells. Even if yours seems fine, there’s a lot going on behind the scenes. A quick once-over by someone who knows what to look for could catch issues early, saving you from being caught off guard in a heatwave.
Scheduling regular check-ups isn’t just a precaution, it’s a long-term investment. It’s simple, but it really does work. I’ve seen plenty of systems that were on their last legs, just because someone skipped an annual check. Don’t let it happen to you.
