When air con fails in Longfield

About 45% of homes across Longfield and its surrounding area date from 1945 to 1972, according to VOA council tax data, and about 82% of households live in detached or semi-detached houses, according to the 2021 Census.

The process
Testing is the last part of the visit wherever the system can be switched on. Then we show you what we have done and answer any questions, and anything that needs a follow-up is pointed out there and then. The visit takes anything from an hour or so to a full day, depending on the fault and the parts. Photos of the existing unit help with repairs and servicing in Longfield.
- You tell us the symptoms, the make and any error code.
- A diagnosis visit finds the cause with proper tests.
- We explain the cause in plain English and give you a fixed price.
- Once you’re happy, the repair is done and any refrigerant work recorded.
- We test the system in operation and leave you a note of the fault and the fix.
Before we arrive
- Find the manual or the paperwork for the system, if you have it
- Let us know if the units are on a roof, a high wall or in a locked area
- Give us access to the outside wall, roof or yard where the outdoor unit sits
How to get a quote
Photos are enough for some jobs; others need a visit first. Multi-room systems, commercial buildings and anything with a long or hidden pipe route are normally surveyed first. Either way, you get a fixed price before any work is booked.

Before you call an engineer
Refrigerant is off limits for anyone without the right qualifications. The law requires anyone working on equipment containing F gas to hold the right qualifications, and the company to be certified, and escaping refrigerant can cause cold burns. If you suspect a leak, switch the system off and call us.
Before you call us about a fault, a few checks can save a visit: check the mode, the set temperature, the remote’s batteries and the breaker. If the breaker trips a second time, leave it off and phone 07833 053749.
Aftercare tips
After the visit, a few habits help:
- Leave space around the outdoor unit
- Write down the fault code if there is one
- Keep to the service interval the manufacturer recommends
After a repair, the basics matter: clean filters every few weeks in heavy use and space around the outdoor unit. A yearly service catches problems before they become breakdowns.
Use the system sensibly. Choose the right mode and a moderate set temperature, and keep doors and windows closed while it runs and the system doesn’t have to work as hard.
What happens if it’s left?
If your air conditioning in Longfield has developed a fault, it’s worth booking a diagnosis now. It takes anything from an hour or so to a full day, depending on the fault and the parts, and you get a fixed price for the repair before any work goes ahead, with a 24/7 line for emergencies. Booking before summer means the work in Longfield is done before the hot weather.
What you pay reflects the actual work. That’s why we look at the job first, from pictures or on a survey, and why the quote is fixed before work begins.

Common questions in Longfield
Is Longfield in your area for air conditioning repair?
Yes. Longfield is one of the places we cover. Get in touch with the details and we reply the same working day.
Is Longfield within the area you cover?
Yes, and the size of the place makes no difference to how we work. A few photos and the postcode are enough to get things started.
Will skipping a service affect the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so check the terms or ask us. Keep every service record either way.
Can you come out for an emergency air conditioning repair?
Yes. Our emergency line runs 24/7 for breakdowns that can’t wait. Ring 07833 053749 with the make, what’s happening and any code and we will talk you through what happens next.
What does the error code on my air conditioning mean?
Each manufacturer uses its own codes, and one code can have more than one cause. Tell us the code, the make and the model, and we will diagnose the fault on site.
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. Every visit is recorded, with F-Gas records where refrigerant work is involved.
Will you make a mess?
We start with protection: sheets over the floor and nearby furniture. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
