How to Choose an Air Conditioning Installer
Air conditioning installation involves handling refrigerants, working with electrics, and getting pipework and drainage right the first time. It's not a job where the cheapest quote is automatically the best value, and it's worth knowing what separates a properly set-up installer from one cutting corners.
We'd rather you ask hard questions before booking any installer, including us, than find out too late that something important was missed.
What to check before you book
- F-Gas certification for the company and the individuals doing the work — this is a legal requirement for handling refrigerant
- Whether they carry out a proper site survey, not just a phone quote
- Whether the quote is written and itemised, not a vague verbal figure
- References or examples of similar work, where available
- Clarity on brands and models being quoted, not just 'an air conditioning unit'
Questions worth asking
- Are you F-Gas registered, and can I see evidence of that?
- Will you carry out a site survey before quoting?
- What's included in the price — installation, commissioning, making good?
- What warranty applies to the unit and to your installation work?
- How do you handle any snags or issues found after installation?
Red flags to watch for
- Quotes given without ever seeing the property
- No mention of F-Gas certification when refrigerant is involved
- Pressure to pay a large deposit upfront with no written quote
- Vague answers about which unit brand or model is being supplied
- No clarity on what happens if something goes wrong after the job
How we approach quoting
We carry out a free site visit before quoting, provide a written, itemised quote with no hidden costs, and can talk through F-Gas certification, warranty terms and the brands we work with — Panasonic, LG and Midea — before you commit to anything.
FAQs
Common questions
Is it worth paying more for a certified installer?
Yes — F-Gas certification is a legal requirement for refrigerant handling, and it also generally reflects a more professional, accountable operation.
Should I get more than one quote?
It's sensible to compare quotes, but make sure they're comparing like for like in terms of unit specification and scope of work.
What if an installer refuses to give a written quote?
That's worth treating as a warning sign — a written quote protects both you and the installer.
Does a lower quote always mean lower quality?
Not always, but a quote significantly below others is worth questioning closely on what's actually included.

Cost & process guides
Planned maintenance versus reactive repairs: which actually costs less?
Reactive repair looks cheaper until you count downtime, stock loss and the shortened life of the equipment.
System & comparison guides
Multi-split vs single-split air conditioning
One outdoor unit running several rooms, or a separate system for each — the choice affects cost, control and what happens if something fails.
System & comparison guides
Fixed air conditioning vs portable AC units
Portable units are a low-commitment stopgap; fixed split systems are the only realistic long-term answer for a room used regularly.
