Work out what size air conditioning a room actually needs — in kW and BTU —
without spreadsheets or guesswork.
Enter the room's dimensions and a few details about how it's built and used.
Air Con Sizer calculates the cooling load and shows you the capacity to look
for, along with matching Daikin wall-mounted systems.
WHAT IT DOES
- Calculates cooling load in kW and BTU from room size and construction
- Accounts for glazing, insulation, ceiling height, occupancy and heat-
producing equipment
- Metric and imperial units
- Generates a PDF report you can save, email or hand to your installer
- Add a "Prepared for" name so the report is ready to pass on
- Suggests Daikin systems in the right capacity range
WORKS ANYWHERE
No signal needed. Everything runs on your phone, so it works in lofts, plant
rooms, empty properties and anywhere else the reception drops out.
No account. No sign-up. No ads. Nothing to pay.
PRIVATE BY DESIGN
Air Con Sizer collects nothing. Room details and names you enter stay on your
device and are never sent anywhere. There is no analytics, no tracking and no
advertising. PDFs are created on your phone and shared only if you choose to
share them.
WHO IT'S FOR
Homeowners planning an installation and want to understand what they need
before getting quotes. Installers and surveyors who want a fast on-site
estimate and a tidy report to leave with the customer.
A NOTE ON ACCURACY
This is an estimate and a planning tool, not a substitute for a site survey.
Room layout, solar gain, airflow and equipment load all affect the final
requirement, and suitability should always be confirmed by your installer
before ordering.
Air conditioning must be installed and commissioned by an F-Gas certified
engineer. Air Con Sizer is provided free by Airvana Solutions, a UK supply-only
Daikin specialist, and the systems it recommends are available from us.
