Book a Diagnostic

Something's not right with your system. We'll work out what, and tell you straight.

A noise that wasn’t there before. Warm air when it should be cold. Water where there shouldn’t be any. Or it’s simply stopped doing anything at all.

A diagnostic is a licensed Alliance technician coming out to find the actual cause, not guess at it. You get a straight answer on what’s wrong, what it takes to fix, and what that costs, before any work starts.

If it turns out to be a small fix, we’ll tell you it’s a small fix.

We’ll call you back to confirm a date and time that works.

How the Diagnostic Works

Here’s exactly what happens once you book.

01
We Come To You

You pick a day that works for you. A licensed Alliance technician comes to your home, and calls you when they're about thirty minutes out so you're not sitting around waiting.

02
We Find Out What's Going On

The technician tests the system properly and works out the actual cause. Not the first thing that looks likely.

03
You See Your Options

We explain what's wrong and lay out your options with a price against each one, so you can see them all clearly. Nothing goes ahead until you've picked one.

Anything You Can Tell Us Helps

None of this is needed to book. If you happen to know it, drop it in the notes.

If you don’t, leave it blank and the technician will sort it out on the day.
