AC Maintenance & Tune-Up in Mission, BC

You might hear unusual sounds like grinding, hissing, or squealing coming from your outdoor unit or indoor vents. Or, you could detect a persistent musty, damp, or burning smell when your AC is running. Noises can signal mechanical issues like failing motors, loose components, or a refrigerant leak.

Musty odors, particularly common in the humid Mission climate, often point to mold or mildew growth in the evaporator coil or drain pan. Burning smells, however, are a safety hazard requiring immediate attention. Mechanical noises can quickly escalate into major component failures, while musty odors can impact indoor air quality and exacerbate allergy symptoms.

If your monthly electricity bill is significantly higher than usual, even though your cooling habits haven't changed, especially noticeable during the summer months in Mission, your AC is likely inefficient. An inefficient AC system works harder and longer to achieve desired temperatures, consuming excessive energy. This can be due to dirty coils, low refrigerant, a malfunctioning thermostat, or poor insulation. You're literally paying more for less comfort, and ignoring efficiency issues drains your wallet while putting unnecessary strain on your AC, shortening its lifespan.

Your AC unit might turn on and off frequently in short bursts, known as short cycling, or it might run almost non-stop without reaching the thermostat setting. Short cycling can indicate an oversized unit, a faulty thermostat, or a refrigerant issue. Continuous running often points to an undersized unit, a significant refrigerant leak, or a problem with the compressor trying to overcome a heavy cooling load, which is common during Mission's peak humidity. Both scenarios put immense stress on the system's components, leading to accelerated wear and tear, inefficient operation, and eventual breakdown.

You might see more dust accumulating on surfaces, or family members could be experiencing increased allergy symptoms, especially during periods of high pollen or wildfire smoke in the Fraser Valley. This often suggests a severely clogged air filter, leaky ductwork pulling in unfiltered air, or an AC system that isn't effectively filtering the air. Poor indoor air quality can exacerbate respiratory issues, allergies, and generally make your home less healthy, while a dirty air filter also restricts airflow, making your AC work harder and reducing its efficiency.

Over time, the evaporator coil (indoor) and condenser coil (outdoor) accumulate dirt, dust, and grime, impeding heat transfer. Similarly, air filters become clogged with dust, pet dander, and other airborne particles. The Fraser Valley's humid conditions can encourage mold and mildew growth on coils, while wildfire smoke periods contribute to rapid filter clogging, making this a particularly common issue in Mission. Professional cleaning of the coils and regular replacement of air filters are crucial to restore proper airflow and heat exchange.

Refrigerant, often called Freon, is the substance that absorbs heat from your home. Low levels are almost always due to a leak in the system, not merely needing a "recharge." While not specific to Mission, BC, issues like corrosion from humidity or physical damage from landscaping can lead to small leaks over time, which are then exacerbated by the heavy cooling demands of summer. A trained technician will locate and repair the leak, then properly recharge the system to the manufacturer's specifications.

Your AC system relies on various electrical components: capacitors, contactors, wiring, and relays, to operate correctly. Over time, these can wear out, corrode, or fail. Fluctuations in power grids or general aging of systems in Mission's older properties can contribute to the wear and tear of these components. The solution involves diagnosis of the faulty component, repair or replacement of the specific part, and ensuring all electrical connections are secure and safe.

As your AC removes humidity from the air, it produces condensation. This water drains away through a condensate line, which can become clogged with algae, mold, or debris. The high year-round humidity in Mission creates an ideal environment for algae and mold to flourish within the condensate drain line, leading to frequent blockages. Clearing the clog, often by flushing the line, and sometimes applying algaecide tablets, can prevent future blockages.

Like any mechanical system, AC components such as motors, bearings, and belts naturally wear down over years of operation. The heavy workload placed on AC units during Mission's intense summer heat events and continuous operation to manage humidity accelerates this natural wear. Regular preventative maintenance is key to inspect these components, lubricate moving parts, and replace worn items before they cause a complete system failure.
