Salons have a heat problem that most shops don’t. Every station can have a hairdryer, straighteners or tongs running, plus bright lighting and a steady stream of clients. In summer the back of the salon can become uncomfortable for staff and clients within an hour of opening.
This guide covers what to think about when cooling a hair, beauty or nail salon: where the heat comes from, choosing and placing units, ventilation for product fumes and keeping the system running well.
Where the heat comes from
When we size a salon system, we count more than floor area. The heat load includes:
- hairdryers, hood dryers, straighteners and tongs;
- lighting, especially older halogen spots and mirror lights;
- clients and staff, which in a busy salon adds up;
- shop-front glazing facing the sun;
- equipment such as wax heaters, towel warmers and steamers in beauty rooms.
A system sized for an empty shop of the same size will struggle on a busy Saturday. Our sizing guide explains the basics.
Comfort at the chair and the basin
Clients sit still for long periods, often with wet hair, gowns and capes. Staff stand and move. A draught that feels pleasant to a stylist can feel chilly to a client at the basin. Good design spreads the air evenly:
- Ceiling cassettes throw air in four directions and suit open salon floors with suspended ceilings. See cassette air conditioning.
- Ducted units hide the equipment above the ceiling with slim grilles, which suits a design-led salon. See ducted air conditioning.
- Wall-mounted units work well in smaller salons and treatment rooms.
We avoid placing outlets directly over basins or styling chairs, and set louvres to keep air moving across the room rather than down onto people.
Treatment rooms need their own control
Beauty, massage and treatment rooms have different needs from the main floor. A client lying still for a facial wants a warmer room than a stylist blow-drying at the front. A multi-split or a system with separate indoor units lets each room have its own setting.
Ventilation for fumes is a separate job
Air conditioning cools and recirculates the air in a room. It doesn’t remove chemical fumes from hair colour, bleach, perm solutions, acrylic nail products or nail polish, and it doesn’t bring in fresh air. That needs ventilation and, for nail work, local extraction at the desk.
Your health and safety risk assessment should cover exposure to products, and local environmental health teams publish guidance for salons and nail bars. When we design a cooling system we look at the existing ventilation and can advise on ventilation systems so the two work together.

Workplace temperature
The HSE says employers must keep the temperature at a comfortable level. It suggests indoor workplaces are generally kept at 16°C or higher (13°C for rigorous physical work), and that there’s no law for a maximum working temperature because every workplace is different. Air conditioning is one of the ways to keep a salon comfortable in summer, and as a heat pump it can warm the salon in winter too.
Hair, hairspray and filters
Salons are hard on air conditioning filters. Fine hair clippings, dust from nail filing and hairspray all find their way into the indoor units. Hairspray can leave a sticky film on filters and coils that traps more dirt. To keep the system efficient:
- rinse indoor unit filters weekly or fortnightly during busy periods;
- sweep and vacuum near units regularly;
- book servicing at least once a year, often more in a busy salon, so the coil and drain are cleaned.
A dirty coil can also cause smells and leaks. See why air conditioning smells.
Noise and the client experience
Salons rely on conversation and music, so quiet indoor units matter. The outdoor unit is usually the noisier part. For shops in a parade, it often goes on the rear wall or a flat roof. If you lease the unit, you’ll usually need the landlord’s consent for the outdoor unit and any wall penetrations.
Costs, VAT and installation
Salon systems are quoted after a survey, because the heat load and layout vary so much. Our prices for a single-room split start at £1,200–£2,200 + VAT; larger salons with cassettes or multi-splits are priced on survey. Business premises pay the standard rate of VAT under HMRC Notice 708/6. We install out of hours, on closing days or early mornings, so you don’t lose appointments. Get in touch for a survey.
Quick answers
What type of air conditioning suits a salon?
Ceiling cassettes suit open salon floors, ducted units suit design-led fit-outs, and wall-mounted units suit smaller salons and treatment rooms.
Will air conditioning remove nail and colour fumes?
No. Air conditioning recirculates room air. Fumes need ventilation and local extraction, which should work alongside the cooling.
How often should salon air conditioning be cleaned?
Rinse the filters weekly or fortnightly in busy periods and have the system serviced at least once a year.
Can you install without closing the salon?
We usually work on closing days, early mornings or evenings to avoid lost appointments.
