Before you call an engineer
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
For air conditioning, cleaning the indoor unit’s filters is the main job owners can do, if the manual says so. They come out, get a gentle clean and go back only when they’re dry. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Commercial air conditioning in Stock, done properly
Every commercial job is commercial systems priced after survey. We look at the building, the people in it, the equipment and the hours it’s used, then send a fixed-price quote. So you know exactly what you’re getting and what it costs. The work covers multi-split systems, server and comms room cooling and ceiling cassettes, and common reasons people get in touch are TM44 recommendations that need acting on and older systems that can’t keep up.
For a hall or similar building near Stock, an air-to-air system that responds quickly suits intermittent use, and it can heat as well as cool.
Some warranty terms depend on the system being serviced regularly by a qualified engineer. Where yours does, a regular service with us keeps that side in order, and every service is written up.

Stock questions
Do you cover Stock for commercial air conditioning?
We do: Stock falls inside our working area. Tell us a little about the job and we’ll take it from there.
Can I fit air conditioning in Stock without planning permission?
There’s no single answer: the building and the outdoor unit position decide it. There’s a conservation area, the Stock Conservation Area, close to central Stock. 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 needed, we check with the local planning authority (for Stock, typically Chelmsford council).
Do you have a 24/7 line?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
Will you make a mess?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Do you provide ongoing maintenance for businesses?
We do, with contracts covering servicing, leak checks and the paperwork. We agree the schedule and cost up front.
Can you look at a system you didn’t fit?
Yes. We start with a proper look and tell you honestly what we find, including anything about the original installation that needs putting right. Any work is priced before it goes ahead.
How soon will you get back to me?
On the same working day you contact us. After that, we agree a survey, diagnosis or installation date that suits you, and you get a fixed price before any work goes ahead.

Landlords, agents and facilities managers
Whether it’s one property or many, you get the same standard: 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. Where a building is let or managed, the lease or contract should make clear who looks after the system and we’re happy to deal with whoever it is.

The process
On the day, we arrive at the time agreed with you and check the plan with you first. Dust sheets go down over floors and anything close to the work, and anything electrical is made safe before work starts. On site, it takes anything from a day or two for a small office to several weeks of phased work on a large building. A note on how to find the property and where to park makes a visit to Stock easier.
- It starts with a survey on site, looking at the space, the people in it and the equipment.
- We send a fixed-price quote showing the system, the unit positions and how the work will be phased.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- We fit the units, run and test the pipework, connect the condensate and wire in the controls.
- We commission the system, record the refrigerant details and hand over the controls and documents.
Before we arrive
- Keep pets out of the rooms we are working in
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Make sure someone can let us in at the agreed time
Get a fixed-price quote
The quickest way to a quote is to send photos: the room or the existing unit, the outside wall or roof where the outdoor unit sits or would go, and the label on any existing unit. Add the address and what you’d like done, and many jobs can be priced from that.

What we are called out for in Stock
Schools and public buildings often need work done in the holidays. We plan installs for holidays and weekends so lessons are not disrupted.
Keep an eye out for any of the following:
- New tenancies needing cooling and heating
- TM44 recommendations that need acting on
- Systems that need out-of-hours or phased installation
For a school like Stock Church of England Primary School, air conditioning work is best done out of term.
Comparing quotes
- Whether a new circuit is included and who certifies it
- Whether the quote shows VAT clearly
- Whether testing, commissioning and paperwork are included
From one of our customers
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
