About Keystone Air Conditioning
Our Story
Keystone Air Conditioning is one man, based in Hornchurch and working across Redbridge, East London and Essex. One name runs the job from your first photo to the last screw. No salesman, and no subcontractor you have never met.
A keystone is the stone that locks an arch together. Here your four photos are the other stones: send them from your phone and one fixed amount comes back in writing, worked out before anyone comes round.
Keystone is new. Fitting starts in spring 2027 and the diary is open now, so the first hot week of next summer finds your room already done.
Our 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.
