Commercial air conditioning in Guildford

Commercial air conditioning in Guildford, done properly

Installation is only the start. Maintenance contracts cover servicing, F-gas leak checks and the records that go with them with the cost agreed up front. There’s a 24/7 emergency line for breakdowns. The work covers multi-split systems, server and comms room cooling and ducted systems, and common reasons people get in touch are comms rooms without enough cooling and new tenancies needing cooling and heating.

Server and comms rooms in Guildford need cooling all year, not just in summer, so a second unit for back-up is often worth it.

AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, with MCS certification for heat pumps and Checkatrade membership. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Looking after your system

Every system needs looking after, and most of it is easy. Our tips:

  • Track when the next TM44 inspection is due
  • Budget for replacing ageing plant
  • Book a maintenance contract to keep servicing on schedule

Make a note of when a TM44 inspection will be due if the system is over 12 kW. We can prepare the system and act on the report.

Simple control settings help. Units heating and cooling the same space at once is a common problem, and we can help set them up.

The process

Refrigerant work is done by qualified engineers working for an F-Gas certified company, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes a few days for a small shop or office, longer for VRF across several floors. For a business in Guildford, we fit around your hours, including evenings and weekends where needed.

  1. We visit the site to look at the building, how it’s used and what the system needs to do.
  2. You get a fixed-price quote with the equipment, the layout and the programme set out.
  3. Installation is scheduled to fit the business, with out-of-hours and phased work where needed.
  4. We fit the units, run and test the pipework, connect the condensate and wire in the controls.
  5. We commission the system, record the refrigerant details and hand over the controls and documents.

Preparing for the visit

  • Make sure we can reach the consumer unit or fuse board
  • Unlock any gate, garage or side passage we need
  • Mention any roof access, ladders or high-level work

Getting a quote

Our prices page gives typical ranges, but your quote is based on your job, because no two buildings, rooms or systems are the same. After a look at the job, by pictures or a survey, the price is fixed. To start, give us a ring on 07833 053749 or drop us a line.

Related advice

Leave it or put it right?

One failing outdoor unit can affect many rooms. Planned maintenance catches issues before they grow and keeps the building comfortable. Planning ahead in Guildford lets you pick the date.

Putting the work off seldom saves money. Faults and wear in a system tend to grow, and a struggling system uses more electricity to do less. If you are not sure what’s needed, phone 07833 053749 or drop us a line and we’ll give you an honest view and a fixed price.

Commercial air conditioning around Guildford

Food Standards Agency data counts about 161 restaurants, cafés and canteens, about 3 hotels, B&Bs and guest houses and about 37 schools and colleges within 1.5 miles or so of the middle of Guildford. Many of those sites need air conditioning that is sized for long hours and maintained on a schedule. About 46% of households live in flats, according to Census 2021 figures. In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind. The Wey and Godalming Navigations Conservation Area is within about a third of a mile of the centre of Guildford. There are 6 conservation areas within a mile of the centre of Guildford. Church of St John the Evangelist, listed at grade II*, is one of roughly 16 protected buildings and structures in the half-mile around Guildford’s centre. If your property is listed or sits inside a conservation area, expect us to raise planning at the survey and to speak to Guildford council, normally the planning authority here where it’s needed.

For a school like Sandfield Primary School, air conditioning work is best done out of term. If you look after a church or hall such as Church of St John the Evangelist, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.

FAQs for Guildford

Do you cover Guildford for commercial air conditioning?

Yes. We work across London and the South East from our base in East Grinstead, and Guildford is part of that. Just phone 07833 053749 or use the quote form with a few details.

What’s the best way to get a price for commercial air conditioning in Guildford?

Use the quote form, or email, with a description of the job. We reply the same working day, and the quote is fixed before any work starts.

Will I need planning permission?

It can do. Heat pumps and cooling-only units are treated differently, and so are flats, listed buildings and conservation areas. We flag anything that may need permission when we survey, and the council has the final say. This is general information, not legal advice.

What F-gas duties does a business have?

The duties depend on how much refrigerant the system holds. From 5 tCO2e, leak checks and records are needed with automatic leak detection at 500 tCO2e and above.

What kind of air conditioning can you install in a business?

Everything from wall-mounted units for single rooms to VRF or VRV systems serving whole buildings. Cassettes and ducted units suit offices, shops and restaurants.

Do you have a 24/7 line?

Yes. There’s a 24/7 emergency line for breakdowns that cannot wait. Call 07833 053749 and tell us what’s happened.

How does the warranty work?

It’s the manufacturer’s warranty, which varies by brand. For instance, Daikin’s standard warranty on split air conditioning is 2 years and we explain the terms for your brand on the quote.

Before you call an engineer

There are a few things you can safely do yourself: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.

Write down what you notice: an error code, a new noise, a drip, a smell or a change in how well the system heats or cools. It makes our diagnosis quicker, and a photo or a short video of the display is even better.

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.”
