AC Repair & Service in Coquitlam, BC

The air coming from your vents feels lukewarm, or there's barely any airflow at all, even after the unit has been running for a while. Your Coquitlam home just isn't getting cool, feeling clammy and uncomfortable. This is often a sign of low refrigerant levels due to a leak, a failing compressor, or an issue with the fan motor or evaporator coil.

Without proper cooling, your home becomes uncomfortable and potentially unhealthy during heatwaves. Ignoring a refrigerant leak can lead to compressor burnout, requiring a much more expensive repair or even a full AC replacement.

You're hearing grinding, squealing, rattling, or hissing sounds coming from your indoor or outdoor AC unit that weren't there before. Grinding often indicates a failing motor bearing, while squealing can point to a worn belt. Hissing usually signals a refrigerant leak, and rattling could be loose components or debris within the system.

These noises are usually precursors to a more serious mechanical failure. Continuing to run an AC with these symptoms can cause significant damage to the compressor, fan motors, or other critical components, turning a minor repair into a major overhaul.

A musty, dirty sock, or even a burning smell permeates your home when the air conditioning is operating. Musty smells often indicate mold or mildew growth in the evaporator coil or condensate drain pan, common with Coquitlam's persistent humidity. A burning smell can mean an electrical issue, an overworked motor, or even a clogged filter causing the motor to strain.

Mold and mildew can significantly impact indoor air quality and exacerbate allergies or respiratory issues for your family. Burning smells are a serious safety concern and indicate parts are overheating, potentially leading to electrical shorts or system failure.

You see puddles of water around your indoor AC unit (furnace) or notice excessive condensation on the unit itself, particularly in areas of your Coquitlam home that typically aren't damp. This typically points to a clogged condensate drain line, a cracked drain pan, or a frozen evaporator coil. When the system can't properly drain the water it removes from the air, it overflows.

Water leaks can cause significant damage to your home's structure, flooring, and ceilings. A frozen coil usually means poor airflow or low refrigerant, which can severely damage the compressor if not addressed promptly.

Your electricity bill is noticeably higher than usual, even though your AC usage hasn't changed dramatically, and your Coquitlam home still isn't as cool as you'd like. An inefficient AC unit has to work harder and longer to achieve desired temperatures, especially when battling the Lower Mainland's humid conditions. This could be due to dirty coils, low refrigerant, a failing compressor, or poor insulation in your home.

Beyond the financial drain, an inefficient system is under constant stress. This accelerates wear and tear, leading to premature failure of components, ultimately costing more in repairs or replacement down the line.

Refrigerant is the chemical that absorbs heat from your home's air, allowing your AC to cool. Low levels are almost always due to a leak in the refrigerant lines or coils, as it's a closed system and shouldn't diminish. Older AC units, still present in many established Coquitlam neighborhoods, are more prone to developing leaks over time due to wear and corrosion from environmental factors.

A Licensed HVAC technician will locate the leak, repair it, and then recharge the system with the appropriate amount of refrigerant, ensuring it's sealed and operating efficiently. This precise work requires specialized tools and expertise.

Air filters become saturated with dust, dirt, pollen, and other airborne particles, severely restricting airflow to your system. Over time, the evaporator and condenser coils can also get coated with grime, hindering their ability to transfer heat effectively. Coquitlam's humid climate, combined with seasonal pollen and periods of wildfire smoke in the Fraser Valley, means filters and coils can get dirty much faster, especially without regular AC maintenance.

Replacing clogged air filters is a simple homeowner task, but for dirty coils, a professional cleaning is required using specialized tools and solutions. This restores proper heat exchange and airflow, significantly impacting your indoor air quality.

Your AC system relies on various electrical components: capacitors, contactors, wiring, and thermostats, to function correctly. Over time, these parts can wear out, burn out, or suffer damage from power surges, leading to system malfunctions. As homes age, so does their electrical infrastructure, meaning older Coquitlam homes might have AC units with aging wiring or components that are more susceptible to these issues.

A qualified technician will diagnose the specific electrical fault, whether it's a faulty capacitor preventing the compressor from starting or a wiring issue. They will then replace the defective component to restore power and function to your air conditioner.

As your AC removes humidity from the air, water collects in a drain pan and flows out through a condensate line. Algae, mold, and sludge can easily build up in this line, causing it to clog and overflow, leading to water leaks. The persistent humidity in Coquitlam and across the Lower Mainland creates an ideal environment for mold and algae growth within the condensate drain system.

Technicians will clear the clog using a wet/dry vacuum or specialized tools, and may flush the line with an algaecide to prevent future blockages. This common issue can often be avoided with regular AC maintenance.
