A pet shop is a sales floor with a till, a door, and housing for animals that must not sit in a cold draught from a comfort unit. Aquariums and vivariums add heat and humidity. Smell needs ventilation. Staff comfort follows HSE workplace temperature guidance. Animal temperatures follow the shop's own husbandry rules, not a guess on this page. A split can cool the aisle people use. It is not an animal-housing design, and it is not the fresh air. An F-gas certified company should install it.

A Saturday aisle between the till and the tanks
Place the indoor unit for the till and the browsing aisle. Aim it so the throw decays before it washes livestock housing, rodent racks or a bird display.
Aquarium heat that is not a tank to cool
Banks of aquariums reject heat and add moisture. That belongs in the load, and it means a wet coil and a real condensate drain. Do not aim extra cooling into an open-top tank to balance it. The cabinet or tank system is separate. Aquarium heat still counts in the room load. The throw should serve the aisle.
A warm Saturday door and the smell in the aisle
The street door on a warm Saturday lets heat in at the front. The till may still be holdable. HSE guidance asks for reasonable comfort for staff and sets no legal maximum. Ventilation for odour is still required. Recirculated cooling will not be the smell control.
- Keep discharge off animal housing.
- Count aquarium and vivarium heat.
- Treat smell as a ventilation problem.
Bedding dust, cage yards and a tank-heater spur
Filters in a pet shop load with bedding dust and hair. They need a short interval and a position you can clean without leaning over an enclosure. A clean filter is maintenance. It is not a welfare certificate.
Outdoor siting, landlord consent and noise still apply. A yard full of storage cages can block a condenser. Power should be a dedicated circuit, not a spur from a tank heater supply.
Stop if the only throw washes the housing
A direct draught on an enclosure is the layout to refuse. If you cannot find a position that misses the housing, say so before the bracket is fixed. The indoor unit should not blow into the tanks or the housings. Condensate must not drip into a display. An F-gas certified company should install the aisle unit, with animal-housing design left out of the comfort job.
Frequently asked questions
What temperature should the pet shop air conditioner be set to for the animals?
This page will not set one. Follow the husbandry rules you already use, and keep the comfort unit's draught off the housing. The setpoint in the aisle is a staff and customer comfort choice. This page will not state a safe temperature for any species. Use the guidance you already run the shop by, and tell the survey which displays must not be in the airstream.
Will air conditioning remove animal odour?
No. It recirculates. Odour needs ventilation. Cooling can make the aisle more comfortable and will not replace fresh air.
