Air Conditioning Maintenance Guide

Scope of Works

• Confirm make, model and F-Gas log-book entries; isolate electrics.

• Remove and clean or replace filters, disinfect evaporator coils and check fins.

• Inspect and flush condensate drains; dose with biocide/algaecide tablets.

• Check system pressures, temperatures and controller fault codes.

• Tighten terminals, test capacitors, fan motors and sensors.

• Record refrigerant level; top-up only if manufacturers’ tolerances breached.

• Provide written service report, efficiency readings and warranty-compliant stamp.
  

Typical Cost (VAT incl.)

Time on Site

Typical 45 – 90 minutes per residential split system. Extra time if units are high on walls, condensers are on a roof/balcony, multiple indoor heads share one outdoor, or deep-clean treatments (evaporator foaming, blower strip-down) are requested.

Questions to Ask Your Tradie

1. Are you F-Gas certified and will you update my log-book?

2. Does the quote cover call-out, labour, cleaning chemicals and VAT?

3. How many indoor units are included before the price rises?

4. Will you test pressures and provide efficiency readings after the clean?

5. What warranty or guarantee do you offer on workmanship and parts?

6. How much extra is refrigerant top-up if you find the charge is low?

7. Can you remind me when the next annual service is due?
   

How to Avoid Surprises

• Reserve close parking for van (vacuum pump and ladder).

• Clear furniture beneath wall units; ensure loft ladders/roof hatches are safe.

• Tell the engineer about any access restrictions (concierge booking slots, lift key, roof permits).

• Locate fused spur or breaker in advance so power can be isolated quickly.

• Advise if pets, smoke alarms or sensitive electronics might be affected by aerosols.

Prices are typical UK averages for 2025 and include 20 % VAT; always obtain a fixed written quotation for your specific system and property.
