About our air conditioning repair in Aldgate
Age alone does not decide whether a repair is worth it. A fan fault on an older unit can be worth fixing, while a compressor failure may tip the balance. We look at the fault, the parts, the refrigerant and how well the system suits the room, then give you an honest view. The work covers heat pumps, wall-mounted split systems and VRF systems, and common reasons people get in touch are water dripping from the indoor unit and a noisy indoor or outdoor unit.
Air conditioning repairs in Aldgate are often in flats, offices and shops, where the outdoor unit may be on a balcony, a rear wall or the roof. Knowing where the outdoor unit sits, and how to get to it, helps us plan the repair.
Refrigerant work is written up in the F-Gas records: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, ready for the next service or a warranty query.

After we’ve gone
A little care keeps the system in better shape. Our advice:
- Let any ice thaw before the engineer arrives
- Only let an F-Gas qualified engineer work on the refrigerant
- Rule out the simple causes first: filter, mode and temperature
After the repair, the system is run and checked in every mode it has. We check it’s cooling or heating as it should and that the fault hasn’t left anything else behind and point out anything else we spotted.
Clean the filters regularly. Blocked filters cut airflow, which can lead to poor cooling, ice on the coil and drips and the manual shows how to clean them.
Common questions in Aldgate
What’s the best way to get a price for air conditioning repair in Aldgate?
The easiest way is to call 07833 053749 or send an email with a few details and photos. Where photos are not enough, a survey comes first and the fixed-price quote follows.
Do you cover Aldgate for emergency air conditioning repairs?
Yes. Our 24/7 emergency line covers Aldgate. Say what the system is doing and whether it shows a code, and we will advise on the next step.
Do you look at the job first?
Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.
Can you repair an R22 air conditioning system?
Servicing with new R22 is not allowed, because it depletes the ozone layer. Some non-refrigerant faults can be repaired if parts are available, but a refrigerant leak typically means replacement. We will set out the options and quote for a replacement where it makes sense.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, plus Checkatrade membership. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Will skipping a service affect the warranty?
Each manufacturer decides. If servicing is in the terms, missing one could affect a claim and we’ll tell you what your brand asks for.
What causes water to leak from an air conditioning unit?
Most leaks come from a blocked drain, a failed pump or a unit that has dropped out of level. Ice on the coil from low airflow or low refrigerant can also melt and drip. Switch the unit off and give us a ring on 07833 053749 or write to us at info@aircondoctor.co.uk.
What we do, step by step
Every visit follows the same order: check the plan with you, put the dust sheets down, do the work, check the system and explain it all to you. The visit itself takes an hour or two to diagnose most faults, with the repair time depending on what we find. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in Aldgate.
- First, a few questions by phone or email about the brand, the fault and anything shown on the controller.
- On the diagnosis visit, the engineer tests the system rather than guessing.
- Nothing is repaired until you’ve heard what’s wrong and agreed a fixed price.
- The repair is carried out, and any refrigerant work is leak tested and recorded.
- Before leaving, we run it through its modes and write up what was found and done.
Before we arrive
- Name a contact who can meet us at the agreed time
- Move furniture away from the wall where we will be working
- Mention any parking restrictions near the property

What affects the quote in Aldgate
Our prices page gives typical ranges, and your quote is built on your job. The quote depends on:
- What electrical work the job needs
- The type of system, from a single split to a larger system
- The size of the job
One room or a whole building, we price it on the same basis: what needs doing, how we get to it and what it needs. The price is fixed before work begins, with VAT shown clearly.
Helping us quote
Good pictures often save a visit. Try to include:
- The outside wall, roof or yard where the outdoor unit sits or would go
- Wide photos of the room or the existing unit
- A close-up of the unit’s label showing the model number
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, the quote is fixed before anything goes ahead.
Landlords, agents and facilities managers
We also work for facilities teams in offices, schools and public buildings across Greater London. Work can be phased by floor, zone or building to keep disruption down.
Where a tenant occupies the property but the landlord owns the system, it’s worth checking the agreement for who looks after the system. We can quote either party, and the paperwork can go to both.
