Need air conditioning in Mildmay?

What owners can safely do

Don’t move, re-route or disconnect units or pipework yourself. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrics need care too. If you need something moved, we can quote for it.

Owner care supports servicing; it does not replace it. Simple care keeps the air moving through the system, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.

Air conditioning installation in Mildmay

Wall-mounted, multi-split, ducted and cassette systems are all part of what we install, with VRF for larger buildings. Which one suits you depends on the space, the building and how much of the unit you want to see, and we explain the options on the survey. Modern air conditioning heats as well as cools: in heating mode they work as an air-to-air heat pump, which is why many owners use theirs all year.

London homes in Mildmay can be short of outside space, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. We look at noise towards neighbours and windows as well as looks, and we plan the pipe route so it’s as short and tidy as the building allows.

Refrigerant work is written up in the F-Gas records: the work carried out, the refrigerant involved and the quantities. File them with the system’s paperwork, as a manufacturer or a future engineer may ask to see them.

Air conditioning in Mildmay: local notes

VOA council tax data put about 48% of homes across Mildmay and its surrounding area before 1919, and the 2021 Census found about 81% of households live in flats. Older homes often have solid walls, which take longer to core drill, so we plan pipe routes carefully and keep them as discreet as we can. For a flat, we look at balconies, flat roofs and rear walls for the outdoor unit, and the lease often needs checking first. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.

About 1.4 miles east stands Sutton House. Listed homes in any area need consent first, so tell us if yours is one.

Mildmay is about 1 mile north of Hoxton, in Greater London. We cover Mildmay for air conditioning and across the rest of Greater London. Our list for Greater London has 764 entries, and Mildmay is one.

Not far from Mildmay, a recent job of ours was on Greenwich High Road, Greenwich (SE10), about 6 miles south-east: installing a Mitsubishi Electric wall-mounted unit in the retail area and a second unit in the stockroom and office. Read more

Common problems we fix in Mildmay

Portable units are often where people start, and why they call us. A portable unit has to vent its warm air through a hose out of a window, which lets some heat back in, and its compressor sits in the room with you. With a split system, the compressor lives outside.

If any of these sounds familiar, it’s worth a diagnosis:

  • Uncertainty over the right type and size of system
  • Bedrooms and offices that overheat in summer
  • Fans and portables that do not keep up

Living close to Church of St Jude and St Paul? Some older properties in parts like that are protected, and the survey finds out whether yours is.

What your quote should include

  • Whether the electrical work is done by a registered contractor, such as NICEIC approved
  • What happens if the job turns out to be different on the day
  • Whether the manufacturer’s warranty depends on regular servicing

Questions to ask before booking

The process

Protection comes first: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. The work on site takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer, and we tidy up before we leave. If your building in Mildmay has a managing agent, a concierge or sign-in rules, mention them when you book.

  1. We survey the property, or work from your pictures for a simple job.
  2. Each room is sized and the unit positions agreed, then you get a fixed-price quote.
  3. On the day, dust sheets go down and the indoor and outdoor units are fitted.
  4. We run and connect the pipes, cable and drain, then pressure test and evacuate the circuit.
  5. It’s switched on, checked and handed over with its records.

Getting ready for the visit

  • Tell us about parking and loading
  • Unlock any gate, garage or side passage we need
  • Dig out any previous service or F-Gas records

Get a fixed-price quote

Every quote starts with a look at the job, either on a site survey or, for simple jobs, from your photos and details. After that, we send a fixed price before any work starts.

Advice

Mildmay questions

Is Mildmay in your area for air conditioning?

Yes. We work across London and the South East from our base in East Grinstead, and Mildmay is part of that. Just phone us on 07833 053749 with a few details.

Is planning permission needed for air conditioning in Mildmay?

That depends on the building and where the outdoor unit goes. Central Mildmay sits inside a conservation area. 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 local planning authority (for Mildmay, usually Islington council).

Do you offer emergency call-outs?

Yes, any time. 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’ll agree what happens next.

Will I get records for the system?

Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.

Where will you put the outdoor unit?

It can go on a wall bracket, at ground level or on a flat roof, wherever the pipe route, airflow and servicing access work best. Noise near bedrooms and boundaries is part of the decision and position can affect planning.

How long does air conditioning installation take?

A single-room system is normally fitted in a day. Multi-room and ducted systems take longer, depending on the pipe routes and access, and we tell you how long on the quote.

Will you need to do electrical work?

Typically, yes. We check your consumer unit on the survey and include any electrical work on the quote and we install and certify the circuit as NICEIC approved contractors.

What affects the cost of air conditioning

A fixed price needs a few facts first. We check:

  • How easy the units are to reach
  • The type of system, from a single split to a larger system
  • The brand, model and parts involved

Several rooms, units or sites on one quote often makes better use of the time. Mention every unit or room you need covered and we will price it together.

Helping us quote

Photos let us diagnose from a distance. Try to include:

  • The make and model of the system, from the label
  • The outdoor side of the property, including any roof or flat area
  • The paperwork from the last service, if you have it

Getting a quote is straightforward. Send a few details and photos, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.

From one of our customers

“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.”
