Four checks that protect your budget

For most shoppers, the quickest route is to calculate an indicative BTU range, compare portable products, then consider a split quotation if noise, heating or frequent use matters more than portability.

CapacityMatch BTU/h to room volume, glazing, insulation and sun exposure.

NoiseCompare minimum and maximum indoor sound figures, especially for bedrooms.

Running costUse rated watts and your own tariff; do not rely on vague efficiency claims.

InstallationPortable units need an exhaust route; split systems need professional installation.
