How we handle air conditioning repair in Duckett's Green
A sealed system shouldn’t lose refrigerant, so if it’s low, there’s a leak. Simply adding gas means it will leak away again. We locate the leak, repair it, test, evacuate and recharge, then record it in the F-Gas records. The work covers heat pumps, ducted systems and wall-mounted split systems, and the jobs we see most are a unit that barely blows any air and a unit that won’t start.
In Duckett's Green, as across London, air conditioning works hard in hot spells, which is when weak cooling, leaks and error codes tend to appear. A photo of the error code and the unit’s label helps us arrive with the right parts in mind.
Each manufacturer sets its own warranty period. For instance, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

FAQs for Duckett's Green
Can you do air conditioning repair in Duckett's Green?
Yes. Duckett's Green is one of the places we cover. Just call us on 07833 053749 or use the quote form with a few details.
Can I get a fixed-price quote for air conditioning repair in Duckett's Green?
The easiest way is to ring 07833 053749 or fill in the contact form with a few details and photos. Where photos aren’t enough, a survey comes first and the fixed-price quote follows.
Can you set up regular servicing?
Yes. Maintenance contracts are part of what we do, set at the interval the system and the manufacturer’s terms need. Each visit is written up, with F-Gas records where refrigerant work is involved.
How long will you be on site?
We’ll confirm the time with your quote. In most cases, it takes a single visit for many faults, while some repairs need a second visit once parts arrive.
Will you work on another installer’s system?
Yes. Systems fitted by other companies are fine from all the leading brands. Send us the make and model, and any records you have.
Can I do the refrigerant work myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is a legal requirement, and manufacturers expect it for their warranty too. We’re happy to quote for the full job, supply to commissioning.
Which accreditations do you hold?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Why deal with it now?
For a newer system, a fault may be covered on the manufacturer’s terms. Tell us the make, model and install date and we will explain how the manufacturer’s terms are likely to apply first. In a London building, getting the freeholder’s or agent’s agreement can take a while, so it’s worth starting early.
What you pay reflects the actual work. That is why every job is looked at first, and why the quote is fixed before work begins.

Keeping the system healthy
Looking after the system is mostly common sense. A few tips:
- If the breaker trips twice, leave it off
- Clear debris away from the outdoor fan
- Keep to the service interval the manufacturer recommends
Once the fault is fixed, we test the system in operation. We confirm it’s working properly and look for anything else that needs attention, and we tell you about anything we noticed.
Give the outdoor unit space. Anything blocking the outdoor unit makes the whole system strain, and debris can get into the fan.
