Need air conditioning in North Harrow?

What we’re called out for in North Harrow

Not everyone is after cooling. Direct electric heaters convert electricity into heat one for one, while an air-to-air heat pump moves heat from outside, so it gives out more heat than the electricity it uses. That’s how most modern split systems work.

Most people get in touch after spotting one of these:

  • A system on old refrigerant that is due for replacement
  • A loft conversion that is too warm to use
  • Portable units that are noisy and barely cope

Homes near Church of St Alban are a good example of where we look up the heritage status of the building before fixing anything to it.

How to choose an air conditioning engineer

Air conditioning in North Harrow

Good air conditioning starts with the right system in the right place. Each room is assessed for its size, windows, direction and how it’s used, and we agree the unit positions and the route for the pipes, cable and drain before you get a fixed-price quote. 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 North Harrow can be short of outside space, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. Neighbours’ windows and noise matter as much as appearance when we choose the position, and we plan the pipe route so it’s as short and tidy as the building allows.

Looking after a system is mostly common sense: keep the outdoor unit clear, follow the manufacturer’s guidance on cleaning and book a service at the interval they recommend. That also helps where the warranty terms ask for regular servicing.

Rented and managed buildings

Facilities teams in offices, schools and public buildings book us too across Greater London. Work can be phased by floor, zone or building to keep disruption down.

Bigger systems bring extra duties: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.

Air conditioning around North Harrow

The Valuation Office Agency’s council tax figures show about 54% of homes in the North Harrow area date from 1919 to 1939. We check the wall construction on homes of that age, as it decides how the pipework goes through. London installs often hinge on outside space, the lease and access to the building.

With historic houses such as Headstone Manor about 0.8 miles north-east, it’s a reminder that older homes nearby may be listed, which changes the planning rules.

Honest limits

We won’t sell you work that doesn’t address the problem, so here are the limits:

  • Heat loss through very poor insulation (a system will heat the room, but insulation is a separate job)
  • An installation that needs consent nobody has given yet
  • Damp or condensation caused by leaks or poor ventilation in the building (that needs the cause fixing)

If you are not sure, just give us a ring on 07833 053749 or fill in the contact form and we will give you a straight answer.

What the work covers

  • VRF systems
  • Wall-mounted split systems
  • Ducted systems
  • Multi-split systems
  • Ceiling cassettes
  • Air-to-air heat pumps

Your questions about air conditioning in North Harrow

Is planning permission needed for air conditioning in North Harrow?

That depends on the building and where the outdoor unit goes. A conservation area takes in the middle of North Harrow. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the planning department at Harrow council, normally the authority for North Harrow when it matters.

Is North Harrow in your area for air conditioning?

Yes, North Harrow is within the area we cover. Just ring us on 07833 053749 or drop us a line with a few details.

Which type of air conditioning is best?

It depends on the rooms and the building. A split suits one room, a multi-split several, a ducted system hides the unit, and a cassette spreads air across larger rooms. We recommend one on the survey and explain why.

Do you have a 24/7 line?

Yes. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Call 07833 053749 and tell us what’s happened.

Do I get paperwork after the visit?

Yes. You get a written record of every visit, including F-Gas records for any refrigerant work. Keep them with the manual and the warranty documents.

Can you look at a system you didn’t fit?

Yes. We work on systems fitted by other installers as well as our own, on all the main brands. Send us the make and model, and any records you have.

Can we book visits on a schedule?

Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.

What happens on the day

If the system has to be off for part of the visit, we tell you before any work starts, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. For a job in North Harrow, tell us about parking, permits and access to the building when you get in touch.

  1. Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
  2. Next, a recommendation for each room and a fixed price.
  3. The treatment: units fitted, pipework and drain routed, and the electrics installed.
  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

  • Tell us about access, such as roof hatches, high walls or locked plant areas
  • Tell us about parking and loading
  • Unlock any gate, garage or side passage we need
