It starts with calculating the thermal loads of the home, sizing the unit according to actual needs, choosing between radiators only, underfloor heating only, or a combination, planning space for the Domestic Hot Water (DHW) tank and outdoor unit, and a fixed price quote.

Professional calculation considers all these factors and correctly sizes the unit. The price difference between a correctly sized unit and a poorly sized one might seem significant at first. The final cost is paid by the end customer visiting the shop or restaurant. A poorly air-conditioned venue loses customers in summer when the heat becomes unbearable. For hospitality businesses, where customer comfort directly determines revenue, the right unit is an investment, not an expense. For hospitality, obtaining a business license may require an air conditioning certificate issued by the installer. When we work with a new venue during the licensing process, we coordinate directly with the municipal inspector to ensure the air conditioning paperwork is ready before the final inspection. Commercial installations above a certain power output (typically 70 kW thermal) require industrial registration and a project signed by an engineer. For medium-sized premises below this threshold, a certificate signed by an authorised installer is sufficient. In all cases, units must have CE marking and comply with European efficiency directives. The F-Gas Regulation also applies and requires registration of refrigerant charges when they exceed certain kilograms.

Burned-out compressor in budget units after 6-9 years of intensive use. This is the most expensive failure. Replacing the compressor costs a significant portion of a new unit's price and is only worthwhile for premium units with reasonable remaining lifespan. For basic units, we usually recommend replacement.
