Your air conditioner works hard to keep you cool and comfortable—especially during warm summer months in Edinburgh and the surrounding areas. Regular care and attention can help your AC run more efficiently, last longer, and avoid unexpected breakdowns.
But when it comes to servicing, it’s important to know what you can safely do at home, and what must be left to qualified professionals.
Here’s our expert guide to what you can (and should) do yourself to keep your air conditioning in great condition—without breaking any rules.
1. Clean or Replace the Air Filter
One of the easiest and most effective tasks you can do is cleaning or replacing your air filter. A blocked filter restricts airflow and reduces efficiency.
Tip: Clean reusable filters with warm water and let them dry fully. Disposable filters should be replaced every 1–3 months depending on use.
2. Keep the Outdoor Unit Clear
Check around your outdoor condenser unit regularly. Remove leaves, weeds, and any debris that could block airflow.
Rule of thumb: Leave at least 30cm of clear space around the unit.
3. Wipe Down Vents and Grilles
Dusty vents and indoor grilles can affect airflow and indoor air quality. Give them a light wipe with a damp cloth or vacuum to keep things clean and healthy.
4. Check for Unusual Noises or Smells
If your AC starts making strange sounds (like rattling or buzzing) or giving off odd smells, it could be a sign of a developing issue.
Action: Turn off the unit and call a qualified technician—don’t try to take it apart yourself.
⚠️ What You Shouldn’t Do
❌ Never handle refrigerant gas or open sealed components.
By UK law, only an F-Gas certified engineer can work on any system that involves refrigerant gas. This includes topping up refrigerant, fixing leaks, or replacing parts that contain gas.
❌ Don’t attempt electrical repairs or open internal panels.
Modern AC systems contain sensitive electronics—leave those to the experts to avoid damaging your unit (or yourself!).
When to Call a Professional
- Your system isn’t cooling properly
- Water is leaking from the unit
- You notice low airflow or strange noises
- It’s been over a year since your last service
