Commercial AC servicing from a Hampshire head office

Plenty of contractors list Hampshire on a coverage map. Rossair’s head office, helpdesk, accounts team and senior engineers have been in Alton for over fifty years - the county is home ground. That means faster response, the same named engineers visit after visit, and a maintenance contract run from twenty minutes up the road rather than a regional call centre.

What’s in a Rossair AC maintenance contract?

SFG20-scheduled servicing

Biannual as standard - pre-summer and pre-winter visits with defined task lists: filters, coils, refrigerant checks, electrical tests, condensate drains, controls validation. Quarterly for high-use sites.

F-Gas and TM44 compliance

Statutory leak checks scaled to refrigerant charge, records retained for the 5-year requirement, and TM44 air conditioning inspections for systems above 12 kW - all rolled into the schedule.

24/7 reactive cover

A 4-hour emergency response under contract, from duty engineers on local rotation. A 24-hour job report follows every reactive visit.

Installation and replacement

Design, supply and installation of splits, multi-splits, VRF and heat pump systems as a Daikin, Mitsubishi Electric and Samsung approved supplier - with end-of-life replacement planned from the maintenance history, not forced by a failure.

Where we work in Hampshire

Winchester, Southampton, Portsmouth, Basingstoke, Andover, Petersfield, Fareham, Eastleigh, Aldershot and Farnborough - offices, schools and colleges, care homes, industrial units and multi-site estates. The longest-running proof sits partly in the county: Chichester College Group, 11 campuses across Hampshire, Sussex, Surrey and Berkshire, maintained for over 20 years.

Why Hampshire estates stay with Rossair

We show up. We do it properly. We send the paperwork. A named account manager, the same engineers year after year, and a compliance pack your auditor can actually use. If you’re paying for AC servicing and still can’t find last year’s F-Gas records, that’s the problem we fix first.

Frequently asked

Air conditioning maintenance in Hampshire - common questions

Which Hampshire towns does Rossair cover for air conditioning maintenance?
All of Hampshire, from the Alton HQ: Winchester, Southampton, Portsmouth, Basingstoke, Andover, Petersfield, Fareham, Eastleigh, Aldershot, Farnborough and the surrounding towns. Alton has been the head office since 1973, so most Hampshire AC servicing is a local journey for the engineer, not a regional dispatch.
How often should commercial air conditioning be serviced in Hampshire?
Twice a year as standard - a pre-summer visit before peak cooling demand and a pre-winter visit for heat pump systems that also heat. High-use environments (restaurants, server rooms, gyms, care homes) need quarterly attention. Rossair schedules to SFG20, which defines the tasks for each visit rather than leaving "service" open to interpretation.
What does an air conditioning service include?
An SFG20-scheduled AC service includes: filter clean or replacement, evaporator and condenser coil cleaning, refrigerant level and leak check under F-Gas, electrical safety and tightness test, condensate drain clearing, controls validation and a performance test against design spec. A service report follows every visit.
Are Rossair engineers F-Gas certified?
Yes. All refrigerant-circuit work - leak checks, recovery, re-gassing, compressor work on splits, VRF and chillers - is carried out by F-Gas certified engineers, as UK law requires. Statutory leak-check records are produced and retained for the 5-year requirement, and TM44 air conditioning inspections are available for systems above 12 kW.
What does commercial air conditioning maintenance cost in Hampshire?
Typical Hampshire pricing: a biannual PPM contract runs £150-£400 per split system per year, with VRF systems priced per indoor/outdoor unit count. Multi-site and campus estates are priced bottom-up from the asset list against the SFG20 task schedule - not per square metre. Rossair surveys before quoting.
Does Rossair install air conditioning in Hampshire as well as maintain it?
Yes. Rossair designs, installs, services and maintains commercial air conditioning - splits, multi-splits, VRF and heat pump systems - as a Daikin, Mitsubishi Electric and Samsung approved supplier. Installation and maintenance under one contractor means the system is maintained by the people who understood it at design stage.
How quickly can Rossair attend an AC breakdown in Hampshire?
Under a PPM contract, a 4-hour reactive response for genuine emergencies anywhere in Hampshire, 24/7. Because the Alton HQ keeps duty engineers on rotation locally, out-of-hours response in the county is typically faster than the contracted commitment. One-off repair calls are also taken - see our commercial HVAC repair page.
