When the summer heat rolls into the Fraser Valley, you’ll want to know that your air conditioner is up to the task. Unfortunately, many homeowners only discover a problem with their cooling system when they need it most, right in the middle of a heatwave.
A little early attention can prevent that scenario altogether. Whether you have central air, a ductless split system, or a heat pump in cooling mode, giving your system a pre-season check is one of the best ways to stay comfortable and avoid costly repairs.
Here’s what to look for, and how to know when it’s time to call in the pros.
Start with a Test Run
Before temperatures start climbing, give your air conditioner a test run:
- Set your thermostat to cooling mode and lower the temperature
- Listen for the system to kick on
- Check whether cool air is coming from the vents
- Let it run for 15–20 minutes and take note of how it performs
If it doesn’t cool evenly, takes too long to kick in, or you hear unusual noises, it’s time for a closer inspection.
Check and Replace Air Filters
Dirty filters are one of the most common causes of AC performance issues. A clogged filter restricts airflow, forces your system to work harder, and can lead to higher energy bills or even frozen coils.
Replace or clean your filter (depending on the type) at the start of the cooling season, and check it monthly through the summer, especially if you have pets or allergies.
Clean the Outdoor Unit
Your condenser unit, typically located outside, needs clear airflow to work efficiently. After a long winter, it may be surrounded by leaves, dirt, or debris.
To clean it:
- Turn off the power to the unit
- Clear vegetation and debris from around the unit (at least 2 feet)
- Use a soft brush or low-pressure hose to remove dirt from the fins
This helps improve performance and prevents overheating as the temperatures rise.
Inspect Thermostat Settings
Your thermostat is more than just a control panel—it directly affects how your system runs. Check the settings to ensure they’re accurate, and consider upgrading to a smart thermostat if you haven’t already.
Programmable thermostats can help reduce energy use by adjusting temperature settings while you’re away or sleeping, without sacrificing comfort.
Listen for Unusual Noises
Your AC should run with a consistent hum. If you hear:
- Banging
- Buzzing
- Grinding
- Clicking during startup or shutdown
…it may indicate loose parts, worn bearings, or electrical issues. Don’t wait to address strange sounds, early repairs can prevent a full breakdown later.
Monitor Airflow and Room Temperature
Check whether each room in your home is receiving adequate cool air. If some spaces feel warmer than others or airflow is weak, it could signal:
- Blocked or closed vents
- Duct leaks
- Dirty evaporator coils
- Fan or blower motor issues
Uneven cooling can lead to overuse of your system, driving up energy bills and stressing your equipment.
Check for Leaks or Moisture
Your air conditioner should never leak water or refrigerant. If you see pooling around your indoor unit, or notice a musty smell when the system runs, it could indicate:
- A blocked condensate drain
- A refrigerant leak
- Mold inside the unit or ductwork
These issues affect performance and can pose health risks—especially during prolonged use in summer.
Know When to Call the Pros
While some AC prep can be handled at home, an annual professional tune-up is your best defense against mid-season problems. A technician will:
- Inspect refrigerant levels
- Test electrical connections
- Clean the condenser and evaporator coils
- Calibrate the thermostat
- Ensure overall system safety and efficiency
At Cohesive Mechanical, our seasonal AC tune-ups are designed to catch problems early, optimize system performance, and keep you comfortable when it counts most.
Considering an Upgrade?
If your current system is:
- More than 15 years old
- Breaking down frequently
- Causing high utility bills
- Struggling to keep up with demand
…it might be time to consider an upgrade. Modern AC systems are quieter, more energy-efficient, and compatible with smart home technology. Our team can help you assess whether a new installation would offer better long-term value.
