Thinking of installing A/C but not sure where to start? Or, perhaps you've got a/c installed already but you're not sure how to operate it?

Well, we have some bullet points for you to bear in mind;

A. LANDLORD AIR-CON & HEAT-PUMP CHECKLIST

Pre-Installation

• Choose low-GWP refrigerants for long-term compliance.

• Ensure installers are fully F-Gas certified.

• Select durable, quiet outdoor units to minimise complaints.

• Consider whole-property ventilation and overheating risk.

Legal & Documentation

• Keep commissioning sheets and service reports on file.

• Ensure safe access for maintenance is provided.

• Clearly document AC responsibilities in tenancy agreements.

Maintenance

• Schedule annual servicing (tax-deductible as maintenance).

• Provide tenants with simple operating instructions.

• Clean filters between tenancies.

When to Upgrade

• Frequent call-outs or rising repair costs.

• Legacy systems using restricted refrigerants.

• EPC improvement goals (AC + heat pump can help).

  
  

B. TENANT AIR-CON USE CHECKLIST

Before Use

• Confirm your landlord approves AC installation if applicable.

• Learn the basic controls, including eco and quiet modes.

Daily Use

• Keep windows/doors closed while cooling.

• Use timers to avoid running AC all day.

• Clean filters (if permitted by the landlord).

Maintenance & Responsibilities

• Report issues early: leaks, noise, weak airflow.

• Do not attempt repairs requiring refrigerant handling.

• Keep the outdoor unit area clean if accessible.

Move-Out

• Return remotes/manuals.

• Inform the landlord of any AC concerns.

  
  

C. NEW-BUILD HOMEOWNER CHECKLIST

Before Finalising Installation

• Check AC is sized correctly for a well-insulated modern home.

• Consider integrated heating/cooling (heat pump).

• Ensure refrigerant is low-GWP and future-proof.

After Handover

• Confirm commissioning documents are included.

• Understand cooling, heating, and ventilation interactions.

• Test summer overheating controls (e.g., night purge ventilation).

Maintenance

• Follow a yearly service schedule.

• Clean filters frequently to maintain air quality.

• Keep track of warranty and installer support details.

Future Planning

• As insulation improves, cooling needs may rise — plan shading, blinds, and ventilation accordingly.
