Hotel air conditioning has to satisfy several groups at once. Guests want a quiet room they can control. Staff in the kitchen, laundry and back office need reasonable working conditions. Owners want reliable equipment and running costs under control. And the building itself may be old, listed or awkward to get pipes through.
Our client list includes Hilton Hotels and Holiday Inn. Whatever the size of the property, the same questions come up, and this guide works through them.
Guest bedrooms
The main options for bedrooms are individual split systems, or a central system such as VRF serving an indoor unit in each room.
- Individual splits are simple, and a fault affects one room. But each needs an outdoor unit, and on a large hotel that means a lot of plant on walls or roofs.
- VRF serves many rooms from shared outdoor units, with long pipe runs possible and central control. Some heat recovery VRF systems can heat some rooms while cooling others, which helps in a hotel where one side gets the morning sun.
Whatever the system, bedroom noise is the priority. We compare manufacturers’ published sound levels at the lowest fan speed, place units away from the bed head, and size them so they can run quietly through the night. Ducted units in the bathroom ceiling or lobby bulkhead are an option where the room layout allows.
Controls matter too. A simple guest controller, a sensible temperature range, and links to key-card or window switches stop rooms being cooled for hours with nobody in them.
Public areas, restaurants and back of house
Receptions, bars, restaurants and function rooms swing between empty and full, often with large glazed frontages. They usually suit cassettes or ducted units sized for peak occupancy. Function rooms in particular need fresh air as well as cooling: air conditioning recirculates room air, and HSE says recirculating systems should be designed with fresh air inlets in its guidance on improving ventilation.
Don’t forget back of house. Kitchens, laundries and comms rooms get very hot. A comms room needs cooling all year and should be on its own system so it isn’t affected when the guest floors are switched over.

Installing in a working hotel
Hotels rarely close for an installation. At survey we agree a programme with you, usually floor by floor or block by block, so rooms can be taken out of sale in groups. We plan noisy work such as core drilling for times that suit you, protect corridors and lifts, and leave each room ready to sell at the end of each phase.
Older buildings need extra thought. Pipe routes through period ceilings, outdoor units on historic facades and condensate routes all take care. For listed buildings, listed building consent is a separate matter from planning permission, and our listed buildings page explains the approach.
F-Gas, TM44 and VAT
A hotel system often holds enough refrigerant to need regular leak checks. GOV.UK’s leak checking guidance sets at least every 12 months for 5 to less than 50 tCO2e and every 6 months for 50 to less than 500 tCO2e, with automatic leak detection required at 500 tCO2e or more. The hotel, as operator, shares responsibility with the service engineer.
Most hotels also exceed the 12 kW total effective rated output that triggers an air conditioning energy inspection at least every five years by an accredited energy assessor. We prepare systems and records for these and fix what they find; see our TM44 page.
HMRC’s zero rate for energy-saving materials in residential accommodation doesn’t extend to hotels: they pay the standard rate of VAT, as set out in Notice 708/6.
Maintenance and replacement planning
Bedroom filters need regular cleaning, and condensate pumps hidden in ceilings are a common source of complaints when they fail. A planned maintenance contract with an up-to-date asset list makes it easier to schedule visits around occupancy and keep F-Gas records in order.
If your hotel still runs older systems, especially any using R22, it’s worth planning replacement before something fails in July. Our guide to repairing or replacing older systems explains the options.
Quick answers
What is the quietest type of air conditioning for hotel bedrooms?
Well-sized wall-mounted units or concealed ducted units can both be very quiet at low fan speed. We compare the manufacturer’s published sound levels and place units away from the bed.
Can a hotel stay open while air conditioning is installed?
Yes, usually. We phase the work floor by floor or block by block so groups of rooms come out of sale for a short time.
Do hotels get the zero VAT rate on air conditioning?
No. HMRC’s zero rate applies to residential accommodation. Hotels pay the standard rate.
Does a hotel need a TM44 inspection?
If the total effective rated output of its air conditioning is more than 12 kW, yes, at least every five years by an accredited energy assessor.
