Commercial air conditioning in Warnham and nearby

System by system

VRF and VRV systems

VRF (variable refrigerant flow), also called VRV, connects many indoor units to shared outdoor units. Rooms can have their own temperature settings making it a common choice for larger buildings.

Hotels and schools

Schools often need installs during the holidays and we plan the programme early.

Commercial air conditioning for homes and businesses in Warnham

Commercial systems are commercial systems priced after survey. The survey covers the space, its occupancy, its heat sources and its opening hours, then send a fixed-price quote. That way the system fits the site and the price is clear before work starts. We are often asked to deal with buildings that can’t close for the work and systems over 12 kW due a TM44 inspection, across server and comms room cooling, multi-split systems and VRF systems.

If you run a village hall or similar building near Warnham, heating and cooling that warms up fast suits a space used on and off.

Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

When to call us in Warnham

Schools and public buildings often need work done in the holidays. Installation can be programmed for the holidays so lessons are not disrupted.

The things we’re asked about most are:

  • New tenancies needing cooling and heating
  • Installs that must fit around trading hours
  • F-gas leak checks and records that are overdue

If you look after a church or hall such as The Parish Church of St Margaret, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.

Questions to ask before booking

  • What records you get at the end
  • Whether the manufacturer’s warranty depends on regular servicing
  • If the quote is based on a survey, pictures or a diagnosis

Choosing an air con installer

Rented and managed buildings

Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We can arrange it, prepare the system for it and fix what it finds.

We regularly work with managing agents. Send the address, what’s needed and how access works, and we’ll send a fixed-price quote.

What we do, step by step

We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the pictures you sent. If something is different, we talk it through with you before carrying on. From there, the work takes anything from a day or two for a small office to several weeks of phased work on a large building. Work in Warnham is booked in advance at a time that suits you.

  1. First comes a site survey of the building, its occupancy and the heat it has to deal with.
  2. The written quote is fixed and lists the plant, where it goes and the order of works.
  3. The work is planned around your opening hours, with out-of-hours or phased work where it helps.
  4. The system goes in, from units and pipework to drainage, wiring and controls.
  5. Commissioning, F-gas records and a handover of the controls finish the job.

Getting ready for the visit

  • Clear access to the fuse board
  • Move furniture away from the wall where we will be working
  • Dig out any previous service or F-Gas records

How to get a quote

Photos are enough for some jobs; others need a visit first. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Warnham questions

Is air conditioning in Warnham permitted development?

It depends on the property. The Warnham Conservation Area takes in the middle of Warnham. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at Horsham council, normally the authority for Warnham.

Is Warnham within the area you cover?

Yes. Warnham is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.

How long will it take to install air conditioning in our building?

A typical installation takes anything from a day or two for a small office to several weeks of phased work on a large building. Phased or out-of-hours work may extend it though it keeps disruption down.

Do you provide ongoing maintenance for businesses?

Yes, and we tailor the schedule to the system and how hard it works. There’s also a 24/7 emergency line for breakdowns.

Can landlords and managing agents book you?

Yes. Homeowners, landlords, agents and businesses all book us in Warnham and across West Sussex. Tell us who should receive the paperwork.

Can I fit air conditioning or a heat pump myself?

The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.

What types of commercial air conditioning do you install?

From one wall-mounted unit to VRF across several floors. Cassettes and ducted units are common choices for open-plan and visible spaces.
