Servicing, cleans and repairs

A yearly service, a deep clean when a unit smells, and repairs for the units I fit, with a yearly care plan.

What to send first

  • The make of the unit, if you know it
  • What it is doing, or not doing

Servicing keeps a unit clean, quiet and efficient. The visit covers the filters, the coils, the drain, the readings and the joints, and you get a written report.

A deep clean strips and cleans an indoor unit that has started to smell. Repairs cover the units I fit: a leak, a blocked drain, a fan that has stopped or an error code on the screen.

The yearly care plan books your service for you and puts you first in the diary in a heatwave. It is offered with every unit fitted.

Values

The quote is what you pay

If your house matches your photos, the amount on your quote is what you pay. If something is different, you are told before any drilling, and you can say no and owe nothing.

You know who is coming

One name on every job, from the first photo to the last screw. No salesman and no stranger at the door.

Your house left clean

Dust sheets down, holes drilled with dust extraction, pipes in neat trunking, everything hoovered and every bit of rubbish taken away.

Frequently Asked Questions

Do you need to visit before you quote?
No. Four photos from your phone are enough for a standard job: the room, the outside wall, the route between them and the fuse board. One fixed amount comes back in writing. If the house turns out different from the photos, you are told before any drilling and can say no.
When can the work be done?
Keystone is new. Fitting starts in spring 2027 and the diary is open now, so you can send your photos today and pick a date before the first hot week. Ventilation work starts in early 2027.
Which areas do you cover?
Keystone is based in Hornchurch and works across Redbridge, East London and Essex.
Can it heat as well as cool?
Yes. Modern air conditioning is a heat pump: the same unit cools the room in a heatwave and warms it in winter.
