- Buildings that can’t close for the work

What happens on the day
We book the visit for a day and time that suit you, and we let you know if plans need to move. On arrival, the engineer compares the job with the survey, your photos or the details you gave us. If something is different, we talk it through with you before carrying on. After that, it takes a few days for a small shop or office, longer for VRF across several floors. Work in Washington is booked in advance at a time that suits you.
- You tell us about the building and what’s needed.
- A site survey confirms the heat load, the layout and the access.
- We set out the options, the price and the programme.
- Installation goes ahead around the business.
- The system is commissioned and maintenance can be arranged.
How to prepare
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Plan for pets to be kept clear during the visit
- Find the manual or the paperwork for the system, if you have it

Related advice
Commercial air conditioning in Washington
Commercial air conditioning comes with F-gas duties for the operator. Leak checks and records are required for systems from 5 tCO2e upwards. We carry out the checks, keep the records and tell you when the next one is due. The work covers ceiling cassettes, ducted systems and wall-mounted split systems, and common reasons people get in touch are commercial systems near the end of their life and installs that must fit around trading hours.
For a hall or similar building near Washington, an air-to-air system that responds quickly suits intermittent use.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

FAQs for Washington
Will air conditioning in Washington need planning permission?
It depends on the property. Central Washington sits inside the Washington Conservation Area. Permitted development only covers heat pumps that aren’t used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with Horsham council, which is usually the planning authority for Washington.
Is Washington in your area for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Washington is part of that. To start, give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk with a few pictures.
How often is a TM44 inspection needed?
The threshold is 12 kW of effective rated output, with inspections at least every 5 years. An accredited energy assessor does the inspection, and we can carry out the recommended work.
Can you work around our opening hours?
Yes, we plan out-of-hours, weekend and phased installs so the business keeps running. We set out the timing before work starts.
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.
Do you carry out TM44 inspections?
TM44 inspections are carried out by accredited energy assessors, which we are not. We get the system ready and act on the findings.
Do you provide F-Gas records?
Yes. It’s your proof of what was done: a dated note of the work, with refrigerant details where they apply.
For landlords and property managers
Records are where property maintenance often slips. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
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’re happy to deal with whoever it is.
What we are called out for in Washington
Heat builds up in commercial spaces from occupants, equipment, lighting and sunshine and windows alone can’t always shift it. Air conditioning sized to the actual heat gain keeps the space comfortable.
It’s time to call us if you’re dealing with:
- F-gas leak checks and records that are overdue
- New tenancies needing cooling and heating
- Systems over 12 kW due a TM44 inspection
For a school like St Mary's CofE Primary School, air conditioning work is best done out of term.

Cooling for Washington businesses
Food Standards Agency data counts about 3 restaurants, cafés and canteens within about 1.5 miles of central Washington. Kitchens and dining rooms gain heat quickly, and hotels need quiet units in guest rooms, so each is designed for its use.
For a church or hall like The Parish Church of St Mary, any outdoor unit needs the right consents first.

Why it’s worth doing now in Washington
An older system on R410A can be kept running, but top-up refrigerant is getting scarcer and dearer. It’s better to replace on your terms than after a breakdown. Small faults tend to grow, so it’s worth dealing with them early.
Our prices page shows typical ranges, but your price depends on the job in front of us. Call for a fixed-price quote, and we will talk you through it.
