Another Surrey summer is here—where the Fraser Valley turns into a giant, sticky embrace from Mother Nature that nobody asked for. Remember that “mild” heat wave in July 2025? The one where temps hit 35°C, humidity clung like a bad ex, and your air conditioner decided to quit right when you needed it most? If you’re a Surrey homeowner staring down the barrel of another sweltering season, you’re not alone. BC’s Fraser Valley saw a significant number of extreme heat days this summer, turning backyards into saunas and basements into swamps. And guess what? Your trusty window unit or central system might be plotting its revenge as we speak.

We’ll explain why humidity is hard on your coils, share safe DIY hacks, and detail how regular tune-ups can slash your BC Hydro bill.

Surrey’s Summer Siege: Why Heat Waves Overwhelm Your AC
Picture this: It’s mid-August in Fleetwood, the air is thick, and your AC is humming loudly—until suddenly, it stops. Why does this happen so often in the Fraser Valley? Blame the combination of scorching sun, Fraser River moisture (leading to 70-80% humidity), and those unique microclimates that make Newton feel tropical while Panorama Ridge enjoys a breeze.
Coastal humidity doesn’t just make you uncomfortable; it accelerates AC breakdowns. Salt-laced winds from the Salish Sea can corrode coils, while muggy air clogs condensate lines, encouraging mold growth. The result? Systems short-cycle (turning on and off rapidly), efficiency drops, and emergency AC repair calls in Surrey spike.
The good news? Understanding these challenges helps you spot trouble early. A pro tip from our Surrey team: If your AC unit is over 10 years old, it may be nearing the end of its service life. Consider pairing it with a heat pump upgrade for efficient cooling in summer and heating in winter.
Key Tip #1: Check your system’s age via the serial number on the outdoor unit. If it was manufactured before 2015, expect a higher likelihood of repairs in humid conditions—it might be time to discuss rebate options with us.

The Top Five AC Issues During Surrey Heat Waves (And How to Identify Them)
Your AC isn’t broken; it’s struggling. Here are the most common Fraser Valley AC problems, based on our 2025 service calls.
1. Frozen Evaporator Coils
You notice lukewarm air from your vents, ice on the indoor coil, and then—nothing. Frozen coils are a frequent issue in humid climates like Surrey’s, often caused by restricted airflow from dirty filters or low refrigerant levels.
Identify It: Reduced cooling, hissing sounds, or water leakage.
Why Surrey? High river-valley humidity keeps coils damp, increasing the risk of freezing.
2. Clogged Condensate Drain Line
Water dripping from your ceiling or a musty smell can signal a blocked drain line. Fraser Valley’s mold-friendly air encourages algae and debris buildup in these lines.
Identify It: Water stains, musty odours, or the AC unit shutting off as a safety precaution.
Local Note: Mineral-rich water in Surrey can accelerate scale buildup in the drain line.
3. Refrigerant Leaks
If your AC is blowing warm air, a refrigerant leak could be the culprit. Coastal conditions can corrode seals and connections, allowing the refrigerant to escape.
Identify It: Hissing from the outdoor unit, warm air indoors, or a sudden increase in your energy bill.
Surrey Specific: Salt air near Boundary Bay can contribute to corrosion.
4. Failing Blower Motor
A grinding or whining noise often points to a blower motor problem. Dust and pollen during Valley summers can overwhelm the motor, especially if the system is short-cycling during heat waves.
Identify It: Unusual noises, uneven cooling, or the fan not working.
Fraser Factor: Wildfire smoke residue can also clog motors more quickly.
5. Faulty Thermostat
Inconsistent temperatures or incorrect readings may stem from a problematic thermostat. Humidity can affect its electronics and wiring.
Identify It: The AC cycles erratically, or the displayed temperature doesn’t match the room’s feel.
Local Insight: Older, drafty homes in areas like Clayton can exacerbate thermostat issues.
Key Tip #2: BC Hydro reports that a significant portion of AC breakdowns stem from neglected filters—replace them monthly during peak summer for better efficiency.

DIY AC Troubleshooting: Simple Fixes for Surrey Homeowners
Before you call a pro, try these safe and simple checks. (Always turn off the power at the breaker before performing any work.)
Check and Replace the Air Filter
A dirty filter restricts airflow, forcing your system to work harder.
How-To: Locate the filter at the return air vent, remove the old one (note the airflow arrow), and insert a new MERV 13 pleated filter.
Time/Cost: 5 minutes, ~$15. Can improve efficiency.
Clear the Condensate Drain Line
A clogged drain can cause water damage and shutdowns.
How-To: Find the PVC drain pipe near the indoor air handler. Pour a 1:1 vinegar and water solution down the pipe to clear algae. Flush with warm water after 30 minutes.
Time/Cost: 20 minutes, low cost. Prevents potential water damage.
Reset the Thermostat
Sometimes, the issue is with the control system.
How-To: Replace the batteries (if applicable) and flip the circuit breaker for 30 seconds to reset it.
Time/Cost: 5 minutes, minimal cost.
Clean Around the Outdoor Unit
Debris like leaves and grass clippings can block airflow through the condenser coil.
How-To: Gently hose off the fins of the outdoor unit and ensure there’s at least two feet of clear space around it.
Time/Cost: 15 minutes, free. Can restore efficiency.
These steps can resolve many common issues. However, if you smell burning or see sparks, stop immediately and call a professional.

When to Call a Professional for AC Repair in Surrey
While DIY can help with minor issues, some problems require a certified technician. Call a pro if you experience:
- No cool air after troubleshooting.
- Strange noises (grinding, screeching, banging).
- Frequent cycling on and off.
- Persistent bad odours.
- Water leaking from the indoor unit.
Ignoring these signs can lead to costlier repairs and potential health risks from heat exposure.

Proactive Maintenance: Your Key to a Cool and Cost-Effective Summer
Preventative maintenance is the most effective way to avoid breakdowns and high energy bills. Implement these practices:
- Bi-Annual Professional Tune-Ups: A spring check-up ($150-$250) includes inspecting refrigerant levels, cleaning coils, and ensuring all components are working correctly, catching most issues early. A fall check-up is also a great time to prepare your gas fireplace.
- Smart Thermostat Settings: Set your thermostat to 24-25°C when home and higher when away. A smart thermostat can automate this, saving you money.
- Keep Vents Open and Clear: Ensure all supply and return vents are open and unobstructed for proper airflow. Vacuum them regularly.
- Use Curtains and Blinds: Closing blinds on south- and west-facing windows during the day can significantly reduce solar heat gain.
- Use Ceiling Fans: Run your ceiling fans counter-clockwise in the summer to create a cooling breeze, allowing you to set the thermostat a few degrees higher.
Consider our maintenance plan for priority service, discounts, and peace of mind. It pairs perfectly with our duct cleaning service for optimal indoor air quality.

Understanding 2025 AC Repair Costs and Savings in Surrey
Being informed helps you budget effectively. For 2025, typical costs in Surrey are:
