About our air conditioning repair in Tolworth
When air conditioning stops cooling, leaks water or shows an error code, the symptom rarely tells you the cause. Warm air can mean anything from a dirty filter to a sensor, board or refrigerant fault, which is why diagnosis comes first. If the problem is a system that needs topping up again and a unit that barely blows any air, we can help.
Many buildings in Tolworth have a managing agent or security desk, so tell us who controls access. Roof access can need keys or permits, which is worth sorting before the visit.
Each manufacturer sets its own warranty period. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. Whatever the brand, the manufacturer’s terms are explained on your quote.

Tolworth questions
Can I get a fixed-price quote for air conditioning repair in Tolworth?
The easiest way is to phone 07833 053749 or fill in the contact form with a few details and pictures. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
Do you cover Tolworth for emergency air conditioning repairs?
The emergency line is open around the clock, and Tolworth is one of the places it covers. Tell us the make, model and any error code when you call; repair call-outs start from £75 + VAT.
Why is water dripping from my indoor unit?
Typically a blocked or kinked condensate drain, a failed condensate pump or a unit that is not level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Turn it off and give us a ring on 07833 053749 or send an email.
My system uses R410A. Can it still be repaired?
Yes, repairs and recharges on existing R410A systems remain legal. As the GB phase-down continues, R410A is getting harder and dearer to buy, so for older systems we compare the cost of a repair with a replacement.
Can I do any of the installation myself?
Not the refrigerant work. The F-gas rules require certified companies and qualified engineers for it, and a new electrical circuit is notifiable building work unless a registered competent person does it.
My air con is showing an error code. What should I do?
Each manufacturer uses its own codes, and one code can have more than one cause. Send us a photo of the display with the make and model, and we will diagnose the fault on site.
Do you work on commercial properties?
Yes. Homeowners, landlords, agents and businesses all book us across London and the South East. Let us know who the records should go to.
When air con fails in Tolworth
VOA council tax data show about 75% of homes in and around Tolworth date from 1919 to 1939, and about 63% of households live in detached or semi-detached houses, according to the last census (2021). Wall bracket, ground pad or flat roof: knowing where the outdoor unit is saves time on the day. In London, access to outdoor units on roofs and balconies can need planning, so tell us how to reach yours. In the mile around Tolworth’s centre, 2 conservation areas have been designated. Day-to-day work on an existing system isn’t affected; a replacement outdoor unit on a protected building might be.
If a system fails at a school such as Our Lady Immaculate Catholic Primary School, our 24/7 line takes the call, and planned repairs can wait for the holidays.

What we do, step by step
If the system has to be off for part of the visit, we tell you before work begins so it doesn’t catch you out. For businesses, we can usually work room by room or zone by zone. The work takes an hour or two to diagnose most faults, with the repair time depending on what we find. Photos of the room and where the outdoor unit could go let us plan most of a visit to Tolworth in advance.
- Describe the problem and the brand, and mention any code on the display.
- A diagnosis visit finds the cause with proper tests.
- We explain the cause in plain English and give you a fixed price.
- Once agreed, the repair goes ahead.
- It’s tested running, and the write-up is left with you.
How to prepare
- Plan for pets to be kept clear during the visit
- Tell us about parking and loading
- Make sure someone can let us in at the agreed time
How to get a quote
Here’s what helps us quote: where the property is and what kind of building it is, pictures of the rooms or units, the brand and model of anything already fitted and any symptoms, from error codes to drips. Then call 07833 053749 or send an email.

Looking after your system
Think of this as the after-treatment advice, short and simple:
- Turn the system off if it’s dripping water
- Write down the fault code if there is one
- Only let an F-Gas qualified engineer work on the refrigerant
If a repair does not make sense, you will hear it from us, and explain why. We can quote for a replacement system on the same visit where that is the better answer.
Clean the filters regularly. Clogged filters starve the unit of air, and that can cause ice, drips and poor performance, so keep them clean as the manual describes.
What a customer said
