How it works
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, do the work, test what we have done and talk you through it. On site, the work takes anything from a day or two for a small office to several weeks of phased work on a large building. Photos of the room and the outside wall help us plan a job near Merrow.
- You tell us about the building and what’s needed.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where needed.
- The system is commissioned and maintenance can be arranged.

Commercial air conditioning in Merrow
Installation is only the start. Maintenance contracts cover servicing, F-gas leak checks and the records that go with them, at a price fixed with your quote. Our 24/7 emergency line is there if something goes wrong. We’re often asked to deal with new tenancies needing cooling and heating and IT rooms that need resilient cooling, across ceiling cassettes, VRF systems and multi-split systems.
Around Merrow, many businesses choose systems that heat as well as cool, useful where old heaters struggle.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

Common problems we fix in Merrow
In schools, the work has to fit around term time. We plan installs for holidays and weekends to keep teaching undisturbed.
These are the situations we see most often:
- Commercial systems near the end of their life
- Systems over 12 kW due a TM44 inspection
- Staff complaining about the temperature
For a surgery or clinic in the St. Luke’s Hospital area, a planned maintenance contract keeps the system clean and its records up to date.

Managing agents and facilities teams in Merrow
From a single flat to a whole estate, the approach is the same: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
Under the GB F-gas rules, responsibility for leak checks is shared between whoever operates the equipment and the engineers who work on it. In a let or managed building, it’s worth agreeing who that operator is, and we can work for either side.
Why deal with it now?
A single system failure in a server room can quickly cause problems. Reviewing the cooling and adding resilience is best done in advance. Planning ahead for a job near Merrow means we can arrive with everything needed.
No two properties are the same, so each one gets its own fixed-price quote. The equipment, how we reach it, the route between units and the work needed all make a difference.

Merrow: your questions answered
Can I fit air conditioning in Merrow without planning permission?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of Merrow holds about 15 listed buildings and structures. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof isn’t allowed under those rules. If there’s any doubt, we ask the local planning authority (for Merrow, usually Guildford council).
Do you cover smaller places like Merrow?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
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.
Is there a survey before the work?
Yes. For simple jobs, pictures and a few details can be enough, while bigger systems and repairs that need testing get a visit.
Is the equipment covered by a warranty?
Warranty comes from the manufacturer and depends on the brand and product. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and we explain the terms for whichever brand you choose.
What does the operator have to do under the F-gas rules?
For systems at or above 5 tCO2e, the operator must have leak checks carried out and keep records. The intervals are at least yearly from 5 to under 50 tCO2e, and 6-monthly from 50 to under 500 tCO2e, and we can handle both.
When will I hear back?
On the same working day you contact us. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.
