As spring arrives, it’s time for homeowners in Surrey and South London to prepare their air conditioning systems for the warmer months ahead. After a long winter of little-to-no-use, your home’s air conditioning unit may need a little TLC to ensure it’s running at peak efficiency before the summer heat arrives.
A well-maintained air conditioning system keeps your home cool, energy-efficient, and free from dust and allergens – but skipping essential maintenance could lead to higher energy bills, poor performance, and unexpected breakdowns when you need cooling the most.
Use this spring air conditioning checklist to make sure your home stays comfortable and efficient all season long.
Why Spring is the Best Time for Air Conditioning Maintenance
✔ Prevent costly repairs by catching small issues early
✔ Lower energy bills by improving efficiency before summer
✔ Improve indoor air quality by removing dust & allergens
✔ Ensure reliable cooling for the hottest months ahead
✔ Extend the lifespan of your air conditioning unit
By taking care of your air conditioning before peak summer demand, you’ll enjoy a cooler home with lower costs and fewer surprises.
Spring Air Conditioning Checklist for Homeowners
1. Test Your Air Conditioning System
The last thing you want is to turn on your AC unit during a heatwave – only to find it’s not working properly!
Switch your system on & check for:
✔ Weak airflow or uneven cooling
✔ Unusual noises (rattling, clicking, or grinding)
✔ Strange smells or musty odours
Run your air conditioning system for 10-15 minutes in spring to check for any performance issues before the temperatures rise.
2. Clean or Replace Your Air Filters
Dirty air filters are one of the most common causes of poor air conditioning performance. When filters are clogged, your system has to work harder, leading to higher energy consumption and poor air quality.
Benefits of clean air filters:
✔ Improves airflow & efficiency (up to 15% savings on energy bills)
✔ Reduces allergens, dust, and bacteria in your home
✔ Prevents unnecessary wear & tear on your AC unit
Replace or clean air filters every 3 months – or more often if you have pets or allergies.
3. Check Your Thermostat Settings
Your thermostat controls the temperature and efficiency of your home’s air conditioning system, so it’s important to ensure it’s working properly.
Spring thermostat checklist:
✔ Test temperature accuracy
✔ Update programmed cooling schedules for warmer months
✔ Upgrade to a smart thermostat for better energy control
If your home still has a manual thermostat, consider upgrading to a programmable or smart thermostat to improve efficiency & reduce energy bills.
4. Inspect & Clean Your Outdoor AC Unit
Over winter, leaves, dirt, and debris can accumulate around your outdoor condenser unit, restricting airflow and reducing efficiency.
How to clean your outdoor unit:
✔ Remove any leaves, dirt, or blockages from the unit
✔ Check for visible damage (bent fins, loose parts)
✔ Ensure proper airflow by keeping plants & furniture clear
Check your outdoor unit in early spring and schedule a professional service if necessary.
5. Schedule a Professional Air Conditioning Service
Even if your air conditioning seems to be working fine, a professional maintenance check can help ensure optimal efficiency and prevent breakdowns.
A spring AC service includes:
✔ Checking refrigerant levels & leaks
✔ Inspecting electrical connections & wiring
✔ Cleaning evaporator & condenser coils
✔ Testing thermostat calibration & efficiency
Book an annual air conditioning service in spring to ensure trouble-free cooling all summer.
6. Improve Your Home’s Energy Efficiency
Keeping your home cool in summer doesn’t have to mean higher energy bills. Small changes can improve efficiency and comfort:
Easy ways to boost energy efficiency:
✔ Use blackout curtains or blinds to keep heat out
✔ Install ceiling fans to improve air circulation
✔ Seal gaps in doors & windows to prevent cool air from escaping
✔ Keep air vents open & unobstructed for better airflow
Combine energy-saving techniques with a well-maintained AC system for maximum comfort & savings.
