Some common problems we deal with when it comes to cooling systems like fridges and walk-in coolers are rotting and shrivelling products, odours, and water leakage. In some cases, these systems cannot maintain the desired temperature, which causes a waste of energy. Our technicians can service, maintain, and repair your freezers. We also install cooling systems for refrigeration units.


AC Maintenance Tips

Your air conditioner is a lifeline during those hot summer days. Ensuring its efficiency not only helps you beat the heat but can also save on energy costs. Here are some AC maintenance tips you should consider:

  • Regular filter replacement: Filters are pivotal in maintaining an air conditioner's efficiency. Replace or clean the filters monthly for optimal performance, especially during high usage seasons. Remember, a fresh filter can improve energy consumption by 5%-15%.

  • Coil care: A dirty evaporator coil decreases airflow and heat absorption. Annually inspect and clean the evaporator coil. Ensure the outdoor condenser coil is free from dirt and debris, maintaining about 2 feet of clear space around it.

  • Clear condensate drains: A clogged drain channel can increase the humidity inside your home, possibly damaging walls or carpets. Use a stiff wire occasionally to ensure the drain is clear.

  • Regular professional checkups: An AC technician will check the refrigerant level, detect and fix leaks, ensure the right electric control sequence, inspect electric terminals, and more.

  • Winter care: If you're not using the AC during winter, cover the outdoor unit or store your window AC to protect it from the cold and debris.

When to Call a Professional

Recognizing early signs of AC troubles and seeking expert intervention is crucial. Wondering when it's best to sideline the DIY toolkit and dial an expert? Here's a breakdown:

  • AC doesn’t start: If your AC refuses to switch on, the issue could range from a simple tripped circuit breaker to a more complex malfunction, like a refrigerant leak. It's wise to consult an expert before diving into the system's intricacies. 

  • Weak airflow: Be it an obstruction in the ductwork, a malfunctioning compressor, or a clogged filter, a professional will pin down and rectify the problem.

  • Emitting warm air: Warm air from your AC during peak summer? Not ideal. This could hint at problems like compromised ductwork, a refrigerant leak, or thermostat issues.

  • Bad odours: A pungent or unusual odour from your AC could indicate mould growth or a potential electrical issue. Such concerns demand prompt, professional attention.

  • Moisture or leaks: Observing moisture or water pooling around your AC is a clear red flag. Unaddressed leaks can quickly lead to extensive home damage.

  • Inconsistent cooling: If your home’s cooling feels patchy—with some rooms icier than others—it could hint at issues like inadequate AC sizing or ductwork complications.

If you face any of these signs with your AC, call our air conditioner repair team in Edmonton today.
