Air conditioning servicing on the south coast

Coastal air is hard on outdoor units. Salt accelerates corrosion on condenser coils and fins, so Portsmouth systems benefit from coil cleaning and protection as part of every service, not as an afterthought when performance drops. Rossair covers the city from its Hampshire base, with the same engineers returning to each site.

Frequently asked

Commercial air conditioning in Portsmouth - common questions

Does Rossair service commercial air conditioning in Portsmouth?

Yes. Rossair services commercial air conditioning across Portsmouth, Fareham, Gosport and Havant to SFG20 - filters, coils, refrigerant checks, electrical tests, condensate drains and controls - with a service report after every visit.

How often should air conditioning be serviced near the coast?

Twice a year as standard, with quarterly visits for high-use sites. Salt air speeds up corrosion on outdoor condenser coils, so coastal servicing should always include coil cleaning and a corrosion check.

Does Rossair install and repair air conditioning in Portsmouth too?

Yes. Rossair installs splits, multi-splits, VRF and heat pump systems as a Daikin, Mitsubishi Electric and Samsung approved supplier, and provides 24/7 repair with a 4-hour emergency response for contract clients.

Which areas around Portsmouth does Rossair cover?

Portsmouth, Fareham, Gosport, Havant, Waterlooville, Portchester, Emsworth and Chichester, as part of Hampshire-wide coverage from the Basingstoke HQ.

What does commercial air conditioning maintenance cost in Portsmouth?

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.
