Commercial air conditioning for Gay Street

About our commercial air conditioning in Gay Street

Buildings whose air conditioning totals more than 12 kW need a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor. We do not carry out the inspection itself, but we prepare the system and do the work it recommends. The work covers server and comms room cooling, ducted systems and ceiling cassettes, and people most often call us about offices that get too hot in summer and comms rooms without enough cooling.

For a business near Gay Street, outdoor units usually have room at the back of the building, out of sight and away from neighbours.

Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

Looking after it afterwards

A little care keeps the system in better shape. Our advice:

  • Keep F-gas records together and up to date
  • Agree sensible control settings for each area
  • Don’t let servicing slip

After commissioning, you get the F-gas records, handover notes and the manufacturer’s paperwork. Keep them together for future servicing and inspections.

Plan replacements before old systems fail, particularly where they use R410A.

How it works

The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. The visit takes from a couple of days for a few cassettes to a planned programme for a whole building. Rural lanes and tight entrances are worth mentioning before a visit to Gay Street.

  1. It starts with a survey on site, looking at the space, the people in it and the equipment.
  2. We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
  3. Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases 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.

How to prepare

  • Unlock any gate, garage or side passage we need
  • Keep pets out of the rooms we’re working in
  • Let us know if the units are on a roof, a high wall or in a locked area

What you can do yourself, and what needs us

Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.

Keep a note of anything odd: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It helps us diagnose quickly, and a photo of the display helps even more.

What affects the cost of commercial air conditioning

The diagnosis comes before the price. The main factors are:

  • The pipe route between the units
  • The type of system, from a single split to a larger system
  • One-off work versus a regular service cycle

Our prices page shows typical ranges, but your price depends on the job in front of us. Call for a fixed-price quote, and we will explain what it covers.

What to send for a quote

Photos and a few facts are often enough to price a simple job. Send what you can of the following:

  • Your installation or service records
  • The rating plate or label on any existing unit
  • The outside wall, roof or yard where the outdoor unit sits or would go

Quoting starts with a diagnosis, from a site survey or, where the job is straightforward, from pictures and measurements. Then you get a fixed price before any work starts.

FAQs for Gay Street

Can I fit air conditioning in Gay Street without planning permission?

That depends on the building and where the outdoor unit goes. Around 7 listed entries sit within 0.5 miles of central Gay Street. An air-to-air system used for heating as well as cooling can be permitted development on a house if it meets the conditions, but a cooling-only unit is not covered, listed buildings need consent and conservation areas restrict outdoor units facing a road. Where necessary, we check with the planning department at Horsham council, typically the authority for Gay Street.

Is Gay Street in your area for commercial air conditioning?

Yes. We work across London and the South East from our base in East Grinstead, and Gay Street is part of that. Get in touch with the details and we reply the same working day.

How soon will you get back to me?

The same working day. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.

How much does commercial air conditioning cost?

We price commercial work after visiting the site. That lets us size the system properly and plan the work, and the quote you get is fixed.

Do you work on all makes?

The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.

Do you survey before quoting?

Yes, always. We diagnose before we treat: the survey shows what’s needed, where things go and what access we need and the fixed price is built on it.

Do you offer emergency call-outs?

Yes, any time. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we will tell you what to do first.
