Air conditioning for Merrow

Merrow: your questions answered

Can I fit air conditioning in Merrow without planning permission?

It depends on the property. The half-mile around the middle of Merrow holds about 15 listed buildings and structures. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Merrow, normally Guildford council).

Do you cover smaller places like Merrow?

Yes, smaller places are covered as well as towns. Send a few details and photos, and we reply the same working day.

Which brands do you work with?

We work with the leading brands, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.

How long does it take to fit air conditioning?

Most single-room systems take 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.

Can you come out in an emergency?

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 tell you what to do first.

Can I use air conditioning to heat a room?

Yes, most modern split systems run as heat pumps, so they heat as well as cool. 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.

Does servicing affect my warranty?

For some brands, yes. Read the manufacturer’s terms, or send us the make and model and we’ll explain them and stick to the interval they set.

How we handle air conditioning in Merrow

Thinking about air conditioning but not sure where to start? Send a few photos of the rooms and the outside walls when you ring us on 07833 053749 or write to us at info@aircondoctor.co.uk, and you’ll hear back from us the same working day about a survey or a fixed-price quote. Most split systems we fit in Merrow are reversible: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, so a system bought for summer earns its keep in winter too.

Many installs in Merrow can go ahead as permitted development, but listed buildings, conservation areas and flats need more care: we flag that at the survey.

In a place like Merrow, the outdoor unit often goes on the ground at the side or rear of the house, where it’s out of sight from the road and easy to service.

Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

Homes in Merrow and air conditioning

The 2021 Census found about 66% of households in detached or semi-detached houses. Detached and semi-detached houses normally have space for the outdoor unit, and several rooms can share one on a multi-split.

Around Church of St John the Evangelist, a quick check of the listing and conservation maps is part of planning any install. Clandon Park (roughly 0.9 miles east) shows the area has its share of heritage. A listed home needs consent before an outdoor unit or pipework goes on.

Merrow is about 2 miles east of Guildford, in Surrey. Properties in Merrow get the same service as everywhere we cover: diagnosis first, a fixed price and proper paperwork when we’ve finished. Across Surrey, we cover 395 places, and Merrow is one of them.

The closest recent job we can point to from Merrow was on Stoughton Road, Guildford (GU2), about 2 miles west: installing a Mitsubishi Electric wall-mounted unit in the living room and a second unit in the master bedroom. Read more

Looking after your system

Aftercare is straightforward, and it makes the next visit easier:

  • Wash or vacuum the filters as the manual describes
  • Do not cover or box in the outdoor unit
  • Keep the room closed while it runs

An annual service keeps the system running efficiently, and some manufacturers make servicing a warranty condition. We can remind you when it’s due, so it doesn’t get forgotten.

Book an annual service. The engineer cleans the coils and drain, checks the electrics and the refrigerant circuit and catches small problems early, and it keeps any warranty servicing conditions in order.

How it works

Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, and electrical work is done by us as NICEIC approved contractors. On the day, both are in the same hands. On site, it takes about a day for a single-room system, longer for multi-room and ducted systems. Around Merrow, access is usually simple, though gates and garden access are worth mentioning.

  1. We survey the rooms and the outside of the property, or work from pictures and details for simple jobs.
  2. We size the system for each room, then send a fixed-price quote with the units and where they go.
  3. Brackets go on, the units are hung and the refrigerant lines, cable and drain are routed between them.
  4. The electrical supply is connected, and the refrigerant circuit is pressure tested and evacuated.
  5. Finally, it’s commissioned, tested in each mode and handed over with the F-Gas records.

Getting ready for the visit

  • Have the make and model of any existing unit to hand
  • Name a contact who can meet us at the agreed time
  • Let us know if the units are on a roof, a high wall or in a locked area

Leave it or put it right?

Fans and portables move warm air around rather than removing it. A fixed system removes the heat to the outside, runs more quietly in the room and can usually heat as well, so it works for you in winter as well. An early booking makes the visit to Merrow easier to arrange.

The price reflects the work, not guesswork. That is why we look at the job first, from photos or on a survey, and why the quote is fixed before we start.

Managing agents and facilities teams in Merrow

Where a tenant occupies the property but the landlord owns the system, the lease or tenancy agreement normally sets out who maintains what. We can quote either party, and the paperwork can go to both.

Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Tell us who the contact on site is and who should receive the paperwork, and we will keep everyone informed.
