A Hampshire building services contractor, not a call centre

Plenty of contractors put Hampshire on a coverage map. Rossair has been based in the county for over fifty years - the company started in Alton in 1973 and the head office is now at Basing View in Basingstoke. Air conditioning sits alongside the rest of the building services work: heating, ventilation, electrical, water hygiene and controls, so one contractor can look after the whole plant room.

Installation and replacement

Design, supply and installation of splits, multi-splits, VRF and heat pump systems for offices, schools, care homes, retail and industrial sites in Hampshire. Rossair is a Daikin, Mitsubishi Electric and Samsung approved supplier, and replacement is planned from the maintenance history rather than forced by a failure.

Breakdown repair, 24/7

Frequently asked

Commercial air conditioning in Hampshire - common questions

Does Rossair install commercial air conditioning in Hampshire?

Yes. Rossair designs, supplies and installs commercial air conditioning across Hampshire - splits, multi-splits, VRF and heat pump systems - as a Daikin, Mitsubishi Electric and Samsung approved supplier. The same engineers then service the system, so it is maintained by people who understood it at design stage.

Which Hampshire towns does Rossair cover?

All of Hampshire from the Basingstoke HQ, including Winchester, Southampton, Portsmouth, Andover, Alton, Fareham, Eastleigh, Petersfield, Aldershot and Farnborough.

How quickly can Rossair attend an air conditioning breakdown in Hampshire?

Contract clients get a 4-hour emergency response anywhere in Hampshire, 24/7, 365 days. One-off repair calls are also taken, and a 24-hour job report follows every reactive visit.

Does Rossair provide other building services in Hampshire?

Yes. Air conditioning is one part of the service. Rossair also maintains heating, ventilation, electrical, plumbing, water hygiene and controls across Hampshire under a single PPM contract with a named account manager.

What does commercial air conditioning maintenance cost in Hampshire?

A biannual PPM contract typically runs £150-£400 per split system per year, with VRF systems priced on indoor and outdoor unit count. Installation is quoted per project after a site survey. Multi-site estates are priced bottom-up from the asset list against the SFG20 task schedule, not per square metre.

Are Rossair engineers F-Gas certified?

Yes. All refrigerant-circuit work - leak checks, recovery, re-gassing and compressor work on splits, VRF and chillers - is carried out by F-Gas certified engineers, as UK law requires. Leak-check records are kept for the 5-year requirement, and TM44 inspections are available for systems above 12 kW.
