Air conditioning servicing in South Hornchurch, done properly
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 tell you which band your system falls into and carry out the checks it needs. If the problem is iced-up coils or pipework and systems that haven’t been serviced for a while, we can sort it out.
In a London area like South Hornchurch, many systems run hard in summer and for heating in winter, which is a good reason for a yearly service. Outdoor units on balconies and roofs pick up city dust and debris, and a clean coil cools better.
AirCon Doctor is an F-Gas certified company and NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

Different systems, different jobs
Condensate drains and pumps
Some indoor units rely on a small pump to move the water. The pump is tested to make sure it works, because a failed pump is a common reason for drips.
Filters
Certain indoor units carry additional filters alongside the main ones. We check these as well and explain what the manufacturer recommends.

FAQs for South Hornchurch
Does my air con in South Hornchurch need a yearly service?
For most homes, once a year. Business systems may also need F-gas leak checks, at least every 12 months from 5 tonnes CO2 equivalent.
How do I get a quote for air conditioning servicing in South Hornchurch?
Send us pictures of the room or the system and a few details about the property. Simple jobs can be priced from pictures; otherwise we arrange a site survey and then give you a fixed-price quote.
Do you have a 24/7 line?
Yes, 24/7. When you call, tell us the make, what’s happening and any error code, and we’ll talk you through the next steps.
Do you cover South Hornchurch?
Yes. We cover South Hornchurch and the rest of Greater London, as part of our area across London and the South East. To book, give us a ring on 07833 053749 or email us.
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.
Why use an F-Gas certified company?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That is not optional: it’s required by law, and AirCon Doctor is certified.
When will I hear back?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Servicing in South Hornchurch: local notes
VOA council tax data date about 47% of homes across South Hornchurch and its surrounding area to the post-war years, 1945 to 1972. If the outdoor unit is high up or behind a locked gate, mention it when you book. City dust and debris build up on London outdoor units, which is why servicing matters.
If you look after a school such as Whybridge Junior School, servicing is easiest in the holidays.

Before you call an engineer
Keep a note of anything odd: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.
Owner care supports servicing; it doesn’t replace it. Simple care keeps the air moving through the system, but the refrigerant circuit, the electrics and the parts you can’t see still need an engineer at the interval the manufacturer recommends.
What we’re called out for in South Hornchurch
How often a system needs servicing depends partly on how hard it works. Heat pumps used for winter heating and units in busy offices, shops or kitchens get through a lot of air, and they benefit from regular attention.
Customers typically contact us when they notice something like this:
- Drips or damp patches below an indoor unit
- A musty or damp smell when the unit starts
- A service that is overdue
Businesses close to Rainham (Essex) station can book an early or late slot so the service doesn’t get in the way of trade.
What to look for in a quote
- Whether a new circuit is included and who certifies it
- What happens if the job turns out to be different on the day
- What the manufacturer’s warranty covers and for how long
How the visit works
Each visit runs to the same pattern: agree the plan on site, protect the area, carry out the job, test what we’ve done and explain it all to you. On site, the work takes around an hour for one indoor and one outdoor unit, with extra time for each additional indoor unit. Before a visit in South Hornchurch, we ask where the van can stop and how we reach the outdoor unit.
- It begins with a few questions about the make, the rooms served and any symptoms.
- The indoor units are opened up and the filters, coils and drain trays cleaned.
- The outdoor unit is cleaned and checked, and debris cleared from around it.
- Electrical connections, controls and refrigerant performance are tested.
- Anything we find is explained, with a fixed price if it needs a repair.
How to prepare
- Let us know if the units are on a roof, a high wall or in a locked area
- Unlock any gate, garage or side passage we need
- Mention any parking restrictions near the property
