What affects the quote in Chelmsford

Typical ranges are on our prices page, and your quote is built on your job. The quote depends on:

  • What state the existing equipment is in
  • The type of system, from a single split to a larger system
  • A single visit or a regular plan

The price reflects the work, not guesswork. That’s why we look at the job first, from pictures or on a survey, and the price is agreed before we start.

Before you get in touch

Photos let us diagnose from a distance. Try to include:

  • The address and the type of property
  • Your consumer unit or fuse board
  • The paperwork from the last service, if you have it

To get a fixed-price quote, phone 07833 053749 or write to us at info@aircondoctor.co.uk and tell us about the property and what you need. A few pictures make it quicker. You’ll hear back from us the same working day.

Air conditioning servicing for homes and businesses in Chelmsford

Whether a leak check is required depends on how much refrigerant the system holds and which refrigerant it is. Under the GOV.UK rules, 5 to under 50 tCO2e means a leak check at least every 12 months, and 50 to under 500 tCO2e means every 6 months. We work out where your system sits and check it accordingly. If the problem is systems that haven’t been serviced for a while and condensate leaking into the room, we can sort it out.

In a place the size of Chelmsford, we service home systems, offices, shops and restaurants. A service cleans the filters and coils, clears the drain, checks the refrigerant circuit and electrics, and tests the system.

Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, and we are happy to talk you through them.

What you can do yourself, and what needs us

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.

Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrical side needs a competent person. Ask us to quote for a move instead.

Keeping systems in Chelmsford running

The Valuation Office Agency’s council tax figures show about 32% of homes in Chelmsford and the neighbourhoods around it were built in 2000 or later. A photo of the outdoor unit and its surroundings tells us what access the visit needs. There are 5 conservation areas within a mile of the centre of Chelmsford. About 17 listed entries lie within half a mile of central Chelmsford, Cathedral Church of St Mary the Virgin (grade I) among them. Day-to-day work on an existing system is not affected; a replacement outdoor unit on a protected building might be.

If you run premises near Chelmsford station, ask about servicing several units in one visit. For a school like Trinity Road Primary School, maintenance visits can be booked out of term.

Your questions about air conditioning servicing in Chelmsford

How often should air conditioning in Chelmsford be serviced?

Once a year suits most home systems. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.

What’s the best way to get a price for air conditioning servicing in Chelmsford?

Send us pictures of the room or the system and a few details about the property. We reply the same working day, and the quote is fixed before any work starts.

Do you look at the job first?

Yes. For simple jobs, pictures and a few details can be enough, while bigger systems and repairs that need testing get a visit.

Will I get records for the system?

Yes. It’s your proof of what was done: the date, the work, and any refrigerant added or recovered.

Who has to arrange F-Gas leak checks?

Responsibility is shared between the operator, usually whoever owns or controls the equipment, and the service technicians. The interval depends on the refrigerant charge, measured in tonnes of CO2 equivalent: at least every 12 months from 5 tCO2e, and every 6 months from 50 tCO2e.

Can landlords and managing agents book you?

Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size in Chelmsford and across Essex. Tell us who should receive the paperwork.

Do you offer air conditioning maintenance contracts?

We do, for one unit at home or many across a site. The visits, what each covers and the price are agreed with your quote and the servicing happens on time.

How the visit works

Testing is the last part of the visit wherever the system can be switched on. Then we show you what we’ve done and answer any questions, and anything that needs attention later is pointed out. All told, the work takes a short visit for one split system, longer for multi-split, ducted or commercial plant. We’ll ask about parking and access in Chelmsford when we book.

  1. We book a time that suits you and confirm the price.
  2. We switch the system on and check it in operation.
  3. We clean the filters, coils and fans and clear the condensate drain.
  4. We check the wiring, controls and refrigerant circuit, and leak check systems that need it.
  5. We run the system again and leave you a service record.

Before we arrive

  • Keep pets and children away from the work area
  • Make sure someone can let us in at the agreed time
  • Find the manual or the paperwork for the system, if you have it

Getting a quote

Published ranges are a starting point; the quote is built on your property, 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 get going, call 07833 053749 or send an email.

Looking after your system

So the system stays in good health:

  • Clear leaves and debris from around the outdoor unit
  • Hold on to every service report
  • Shut doors to the room so the system isn’t cooling the whole house

The best time to book the next service is now, while you remember. Many people book in spring, before the cooling season, or in autumn if they use the system for heating, though any time of year works.

Book a service at least once a year with extra visits where the system runs constantly or needs more frequent leak checks.

A customer’s words

“Excellent service from start to finish. Two wall-mounted units installed in our home. Clean, tidy work: they protected all the floors and left no mess. The systems work brilliantly. Would highly recommend.”
