Commercial air conditioning in Marylebone, done properly

Commercial systems are commercial systems priced after survey. The survey covers the space, its occupancy, its heat sources and its opening hours, and a fixed-price quote follows. So you know exactly what you’re getting and what it costs. The work covers ceiling cassettes, ducted systems and multi-split systems, and the jobs we see most are leak check schedules that have slipped and ageing air conditioning that keeps breaking down.

Commercial systems in Marylebone are often in shared buildings: offices above shops, restaurants below flats. That means planning noise, outdoor unit positions and access with the landlord or managing agent, and the work is typically planned around trading hours.

Any work on the refrigerant circuit is recorded: the work carried out, the refrigerant involved and the quantities. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

What the work involves, system by system

F-gas records and TM44

For systems from 5 tCO2e upwards, the operator is responsible for leak checks and records. We carry out the checks and provide the records.

Hotels and schools

In hotels, each room needs its own control and installation has to be planned around occupancy. Phased installation keeps rooms available.

How it works

Wherever the system can be run before we leave, we run it and check it in operation. Then we show you what we have done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes anything from a day or two for a small office to several weeks of phased work on a large building. Before a visit in Marylebone, we ask where the van can stop and how we reach the outdoor unit.

  1. First comes a survey, looking at the building and how it’s occupied.
  2. We recommend a system and send a fixed-price quote.
  3. The programme is agreed, including any out-of-hours or phased work.
  4. The system is installed, wired and connected to its controls.
  5. Commissioning and handover follow, with the F-gas records and manufacturer paperwork.

Before we arrive

  • Clear a path to the units and the space around them
  • Make sure we can reach the outdoor unit, or where it will go
  • Dig out any previous service or F-Gas records

What commercial work looks like in Marylebone

The FSA’s food hygiene register shows about 3,845 restaurants, cafés and canteens, about 267 hotels, B&Bs and guest houses and about 80 schools and colleges within 1.5 miles or so of the middle of Marylebone. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use. Valuation Office Agency council tax records put about 50% of homes in and around Marylebone before 1919, and Census 2021 figures found about 92% of households live in flats. Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care. London commercial jobs usually involve a landlord or managing agent, and plant space is often tight.

Before any plant goes outside a building like Russian chapel on Welbeck Street, its trustees may need planning or heritage advice, and we work with whoever gives it. For a surgery or clinic in the Respiratory Clinical Trials area, a planned maintenance contract keeps the system clean and its records up to date.

FAQs for Marylebone

Can I have air conditioning in a flat in Marylebone?

In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.

Can you do commercial air conditioning in Marylebone?

Yes. Marylebone is one of the places we cover. Just call us on 07833 053749 or write to us at info@aircondoctor.co.uk with a few details.

Are you F-Gas certified?

We are an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are also Checkatrade members.

Whose job is it to check the system for leaks?

Responsibility is shared between the operator, typically whoever owns or controls the equipment, and the service technicians. How often depends on the size of the refrigerant charge in tonnes of CO2 equivalent: at least yearly for 5 to under 50 tCO2e, and every 6 months for 50 to under 500 tCO2e.

What F-gas duties does a business have?

For systems at or above 5 tCO2e, the operator must have leak checks carried out and keep records. Checks are at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e, and we can handle both.

When is a TM44 inspection required?

Systems with an effective rated output over 12 kW need a TM44 inspection at least every 5 years. An accredited energy assessor carries it out and we can help before and after.

Can you come out in an emergency?

Yes. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we will agree what happens next.

Rented and managed buildings

Facilities teams in offices, schools and public buildings book us too in Marylebone and across Greater London. Larger buildings can be done in stages to keep disruption down.

The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. In a let or managed building, it’s worth agreeing who that operator is and we’re happy to deal with whoever it is.

What a customer said

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
