Before the summer heat and humidity arrive in London, preparing your air conditioner is essential. Annual maintenance not only prevents unexpected breakdowns but also improves efficiency and extends your unit's lifespan. Here’s a checklist from Hawana HVAC combining DIY tasks and professional service.
DIY Maintenance Tasks for Homeowners
These simple steps can be done without a professional and make a huge difference in your AC's performance.
- Change Your Air Filter: This is the single most important task. A clogged filter restricts airflow, forcing the system to work harder. Check it monthly and replace it at least every 90 days.
- Clear the Outdoor Unit: Remove leaves, grass clippings, twigs, and other debris from around your condenser unit. Ensure at least two feet of clear space for proper airflow.
- Clean the Condenser Coils: After turning off the power at the breaker, use a garden hose (on a gentle setting) to spray down the exterior fins, washing away dirt and grime.
- Check the Condensate Drain Line: Ensure the drain line isn't clogged. If you notice standing water or blockages, a professional cleaning is needed to prevent water damage.
Professional AC Tune-Up Checklist
While DIY steps are helpful, a professional tune-up from a licensed technician is crucial for system health and safety. Here’s what a Hawana HVAC pro will do:
- Inspect Electrical Components: Tighten connections, measure voltage, and check contacts to prevent electrical failure, a common issue in overworked systems.
- Check Refrigerant Levels: Too little or too much refrigerant (like the older R-22 or modern R-410A) indicates a problem and harms efficiency. We'll ensure levels are perfect.
- Lubricate Moving Parts: Proper lubrication of motors and bearings reduces friction and electricity use, preventing parts from wearing out prematurely.
- Clean Evaporator and Condenser Coils: We perform a deep cleaning beyond what a hose can do, removing caked-on grime to restore heat absorption and transfer capabilities.
- Thermostat Calibration: We ensure your thermostat is calibrated correctly so it accurately reads the room temperature and cycles the AC appropriately.
Action: An annual professional tune-up is the best way to catch small issues before they become major, expensive repairs in the middle of a London heatwave.
