How we handle commercial air conditioning in Hornchurch Marshes
Once a system is in, it needs looking after. A maintenance contract keeps servicing and leak checks on schedule, with the records kept up to date, at a price fixed with your quote. Our 24/7 emergency line is there if something goes wrong. We are often asked to deal with work raised by a TM44 inspection and installs that must fit around trading hours, across multi-split systems, server and comms room cooling and VRF systems.
London buildings in Hornchurch Marshes can have little space for outdoor plant, so roofs, light wells and basements are common positions. VRF systems can serve many indoor units from a small number of outdoor units.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll tell you how the manufacturer’s warranty is likely to apply before anything chargeable is done.

Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Keep F-gas records together and up to date
- Plan regular servicing with a contract
- Tell us early about fit-outs or changes of use
If the system needs F-gas leak checks, we diary the first one and we can cover it under a contract.
Keep records of every service, leak check and repair. For systems at or over 5 tCO2e, they’re required.
Let and managed properties
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed-price quote.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Let us know who will give us access and who the records should go to, and we’ll keep everyone informed.
The process
We book the visit for a day and time that suit you, and we keep you posted if anything changes. 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. From there, the work takes anything from a day or two for a small office to several weeks of phased work on a large building. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Hornchurch Marshes.
- First comes a survey, looking at the building and how it’s occupied.
- You get our recommendation and a fixed price.
- The programme is agreed, including any out-of-hours or phased work.
- The system is installed, wired and connected to its controls.
- We commission the system and hand over the F-gas records and controls.
How to prepare
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Mention any parking restrictions near the property
- Dig out any previous service or F-Gas records

Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. In London, commercial installs often need landlord consent, agreed plant positions and out-of-hours working.
If you run a surgery, clinic or pharmacy in the area around Erith and District Hospital, about 2.8 miles south, cleanable, quiet units and regular maintenance matter. Churches and halls such as Church of St Helen and St Giles are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.

What owners can safely do
Refrigerant is off limits for anyone without the right qualifications. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and escaping refrigerant can cause cold burns. A suspected leak is our job, not yours.
Owners can handle the everyday basics: keep the outdoor unit clear of leaves, plants and clutter, check the settings and the remote, and follow the cleaning the manual describes. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Hornchurch Marshes: your questions answered
Is Hornchurch Marshes in your area for commercial air conditioning?
Yes. Hornchurch Marshes is one of the places we cover. To start, call 07833 053749 or write to us at info@aircondoctor.co.uk with a few pictures.
Do I need permission to put air conditioning in my flat in Hornchurch Marshes?
Usually, yes, though leaseholders normally need the freeholder’s agreement. 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.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
How much does commercial air conditioning cost?
Commercial systems are priced after a site survey. The building, the heat load, the system type and the programme all affect the cost and the quote is fixed before we begin.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Can I fit air conditioning or a heat pump myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That’s a legal requirement, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Do you offer commercial maintenance contracts?
Yes, and we tailor the schedule to the system and how hard it works. For breakdowns, there’s a 24/7 emergency line.

A customer’s words
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
