Air conditioning for Thornton Heath

For landlords and property managers

Portfolio owners often want one contractor and one number. Our area covers Greater London and the South East, so work at different addresses can be planned together and kept to a regular schedule.

Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party and send the records to whoever needs them.

Air conditioning for homes and businesses in Thornton Heath

Think of it as diagnose, treat and sign off: the survey diagnoses what the rooms need, the installation is the treatment and commissioning is the sign-off. At sign-off, the system is tested in each mode, the controls are explained and the F-Gas records are left with you. A lot of the calls we get from Thornton Heath are about one room that is too hot to sleep or work in. A single-room split system is often the answer, from £1,200 + VAT.

London homes in Thornton Heath can be short of outside space, which means a rear wall bracket, a flat roof or a balcony is often the best spot for the outdoor unit. Neighbours’ windows and noise matter as much as appearance when we choose the position, and the pipe run is planned to be short, neat and out of the way.

Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, so we go through them with you rather than leave you to find the small print.

What happens on the day

Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. The work on site takes anything from a day for one room to several days for a multi-room or ducted system, and we tidy up before we leave. Photos of the room and where the outdoor unit could go let us plan most of a visit to Thornton Heath in advance.

  1. Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
  2. Then the prescription: the right system and size for each room, on a fixed-price quote.
  3. Then the work: units up, pipes and drain run, and a new circuit where necessary.
  4. Before it runs, the pipework is proved tight and put under vacuum.
  5. The sign-off: commissioning, a walk through the controls, and the F-Gas records and warranty details.

Getting ready for the visit

  • Mention any parking restrictions near the property
  • Clear access to the fuse board
  • Mention any managing agent or landlord rules we need to follow

How to get a quote

Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.

How we price air conditioning

The survey or diagnosis tells us what the work involves. We look at:

  • The brand, model and parts involved
  • What kind of system it is
  • How many units are involved

Several rooms, units or sites on one quote can make for a more efficient booking. Mention every unit or room you need covered and we will price it together.

Helping us quote

You do not need the technical terms. It helps if you can send:

  • The address and the type of property
  • Your consumer unit or fuse board
  • A close-up of the unit’s label showing the model number

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, the quote is fixed before anything goes ahead.

What you can do yourself, and what needs us

Some faults have simple causes you can check first: check the mode, the set temperature, the remote’s batteries and the breaker. If a breaker trips again after you reset it, leave it off and ring us on 07833 053749 or send an email.

Do not 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 electrical side needs a competent person. Ask us to quote for a move instead.

Thornton Heath: your questions answered

Can I get a fixed-price quote for air conditioning in Thornton Heath?

Start with a short message: the address, what you need and a picture or two. We reply the same working day, and the quote is fixed before any work starts.

Can you fit air conditioning in a London flat in Thornton Heath?

Often, yes, but the lease and the freeholder typically have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.

Can air conditioning heat my home as well?

Yes, most modern split systems run as heat pumps, so they can heat a room in winter. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. Some cooling-only models exist, so we confirm it for the model on your quote.

What does F-Gas certified mean?

Anyone installing, repairing or servicing the refrigerant side must be qualified, and their company certified. Ask to see proof before you book anyone, and we’re happy to show ours.

Are you F-Gas certified?

F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.

Do you look at the job first?

Yes. Photos often do the job for simple work, while larger systems and faults that need testing are seen on site.

What warranty do I get?

The manufacturer provides it, on its own terms. Some brands make regular servicing a condition so it’s worth keeping the service records.

Air conditioning around Thornton Heath

Valuation Office Agency council tax records put about 53% of homes across Thornton Heath and its surrounding area before 1919, and Census 2021 figures found about 39% of households in terraced houses. Older properties often mean solid walls and period details, so pipe runs are planned to stay neat and out of sight. With a terrace, the back wall or an extension roof is typically the best place for the outdoor unit. For a London home, we plan the outdoor unit position, the pipe route and any approvals before the day.

Homes near Church of St Stephen are a good example of where we look up the heritage status of the building before fixing anything to it. Kingswood House, about 2.4 miles north-east, is one of the historic houses nearby, and if your own home is listed, consent comes before any air conditioning is fixed to it.
