The temperature is rising in Surrey and South London – many homeowners are switching on their air conditioning for the first time since last summer. But before you sit back and enjoy the cool air, give your system a quick health check to make sure it’s running safely and efficiently.
✅ Check filters are clean
Dirty filters reduce airflow and make your air conditioning system work harder, costing you more in energy bills.
✅ Make sure your outdoor unit isn’t blocked
Remove any leaves, plants, or garden clutter that may be obstructing airflow around the unit.
✅ Listen for unusual noises
Banging, buzzing or clicking sounds might mean something’s wrong with your fan motor or compressor.
✅ Check airflow at each vent
Weak airflow can indicate a blocked duct or a fan issue.
✅ Notice any strange smells?
A musty smell could mean mould in the system. A burning smell could mean something serious.
If you’re unsure about any of these vital signs, give us a call. One of RC Cooling’s friendly domestic air conditioning engineers are here to help homeowners across Surrey and South London – keeping systems safe, efficient, and ready for the hot summer ahead.
