Air con installers in Erith
Most modern split systems run as heat pumps, so they can heat as well as cool. The Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning, so a well-chosen unit can be useful in winter as well as summer. Modern air conditioning heats as well as cools: the Energy Saving Trust notes that air-to-air heat pumps are sometimes called air conditioning, so a system bought for summer earns its keep in winter too.
London homes in Erith can be short of outside space, so the outdoor unit may end up on a rear wall, a flat roof or a balcony. We look at noise towards neighbours and windows as well as looks, and the pipe run is planned to be short, neat and out of the way.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. It makes the next visit quicker and any warranty question simpler, so keep it safe.

How it works
We keep the work area tidy as we go, with dust sheets down and offcuts and packaging cleared up. Any holes, fixings or cable routes are agreed with you before we drill. On site, it takes a day for most single-room installations, with multi-split, ducted and cassette systems taking longer. Pictures of the space and the outside wall help us plan the work in Erith.
- Diagnosis comes first, with a survey of the rooms, outside space and fuse board.
- Next, a recommendation for each room and a fixed price.
- Then the work: units up, pipes and drain run, and a new circuit where necessary.
- Testing: the circuit is pressure tested and evacuated before the refrigerant is released.
- Finally, the clean bill of health: commissioning, the controls explained and your paperwork handed over.
How to prepare
- Clear a path to the units and the space around them
- Name a contact who can meet us at the agreed time
- Dig out any previous service or F-Gas records
How to get a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.

Common questions in Erith
Can you do air conditioning in Erith?
Yes, Erith is within the area we cover. Just phone us on 07833 053749 with a few details.
Do I need permission to put air conditioning in my flat in Erith?
Often, yes, but the lease and the freeholder typically have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Are you F-Gas certified?
F-Gas company certification, NICEIC approval for electrical work and MCS certification for heat pumps, and we’re Checkatrade members. Our engineers also hold the individual F-gas qualifications needed to work on refrigerant.
Do you provide F-Gas records?
Yes. It’s the record a manufacturer or the next engineer will ask to see: a dated note of the work, with refrigerant details where they apply.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we will propose a schedule and quote for it. That can include the leak checks the F-gas rules require for larger systems.
Can you fit air conditioning in a leasehold flat?
In many cases, but permissions come first. Leaseholders normally need consent from the landlord or management company for an outdoor unit and holes through outside walls and the lease will say. Planning rules for flats are tighter too, and we flag anything that may need permission. This is general information, not legal advice.
Do I need to service the system to keep the warranty?
Check the manufacturer’s terms. Some warranty terms require the system to be serviced regularly by a qualified engineer, so it’s worth checking. Either way, keep a record of every service.
Pricing air conditioning in Erith
The price is fixed before any work begins. It takes into account:
- What state the existing equipment is in
- The type of system, from a single split to a larger system
- What electrical work the job needs
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. You will have a fixed price before work begins, and the quote sets out the VAT.
What we need to know
Before you ask for a quote, gather:
- A close-up of the unit’s label showing the model number
- Any previous service or F-Gas records
- Where the outdoor unit is, or where you’d like it
If you need air conditioning in Erith, ring us on 07833 053749 or send an email. Let us know the type of property and what you need, plus some pictures if they’re to hand. We reply the same working day.
Looking after your system
After the visit, a few habits help:
- File the paperwork with the manual
- Shut doors and windows when it’s on
- Flag any change in how the system sounds or performs
Commissioning is the last stage: every mode is tested before we go. Once it’s running properly, we take you through the controls and settings, so you’re confident using it.
Give the outdoor unit room to breathe. Leaves, plants, bins and stored items around it restrict the airflow, which makes the whole system less efficient.
Do you need air conditioning in Erith?
Some people come to us for heating rather than cooling. Direct electric heaters convert electricity into heat one for one, while an air-to-air heat pump moves heat from outside, which means more heat out than electricity in. Most modern split systems work this way.
What we’re most often called about:
- A loft room or top floor that bakes in summer
- An office, shop or restaurant that is uncomfortable for staff and customers
- An ageing air conditioning system near the end of its life
If you work from home near Erith station, a home office that overheats is one of the easiest rooms to cool.
