THE 60-SECOND VERSION

Hiring an air conditioning engineer in five steps

  1. Are you a trader, and can I see that in writing?No register covers air conditioning engineer work, so trader status is what your consumer rights hang on — testing the system — testing the system for proper functionality.
  2. How does complexity of the repair change the price?Wear and tear adds repairs the job did not originally include. — ask before the quote rather than after.
  3. How does type of air conditioning unit change the price?A job left too long costs more than one done on time. — ask before the quote rather than after.
  4. How does what does this service include? change the price?It changes both what is used and how long it takes. — ask before the quote rather than after.
  5. What is not included?Repair or replacement — repair or replacement of faulty components — get the exclusions named in the quote, because a air conditioning engineer job is priced on what was agreed and not on what was assumed.

BEFORE YOU BOOK

Check before you book

No register applies

NO REGISTER APPLIES TO PLUMBING ITSELF. Anyone may trade as a plumber. The line that does exist is gas: any work on a gas appliance or gas pipework is restricted to the Registered Gas Installer scheme, and a plumber who is not on it may not touch the gas side of a boiler however competent they are at everything else. Ask which side of that line your job falls on before you book.

Look for the trader badge and the ID-checked badge on the Locufy profile — both are checked by us, not claimed by the provider.

What to check instead

Whether any part of the job touches gas — if it does, the gas register applies and a plumbing qualification is not a substitute; A trade qualification or apprenticeship, which is voluntary but checkable; Public liability insurance, and who the insurer is; Whether they carry the parts or price them separately; A written scope naming what is isolated, drained and reinstated; How a leak discovered mid-job changes the price, agreed in advance.

Ask for each of these before you agree a price, and get the answers in the same message as the quote.

Insurance

Expect public liability, and ask specifically about water-damage cover. From a company, ask for the insurer, the limit and the VAT number, and ask who actually attends: the team that turns up may be employed, subcontracted or both, and only one of those is supervised by the firm you are paying.

Ask to see the current certificate of insurance — the insurer's name, the limit and the date it runs to.

Trader or private seller

Under the Consumer Rights Act 2022 a trader must tell you they are a trader, and your consumer rights — work carried out with reasonable skill and care, and a cooling-off period on a contract agreed in your home or online — apply to traders and not to private sellers. On Locufy the trader status is shown on the profile.

Look for the trader badge on the Locufy profile, and ask anyone else for it in writing before you agree a price.

VAT

VAT at 13.5%, the reduced rate Revenue publishes for this service. Ask whether the price you were given includes it. A trader under the €42,500 registration threshold does not charge it; one over it must, and must show it separately.

Ask whether the figure you were given includes it, and for the VAT number if they are registered — Revenue publishes the rate for this service. revenue.ie →

  1. Look firstComplexity of the repair — wear and tear adds repairs the job did not originally include — that is what the air conditioning engineer is judging on the first visit, and a price given without it is a guess.
  2. Agree what is being doneType of air conditioning unit — a job left too long costs more than one done on time — put in writing before anyone starts, because it is the document you both read back at the end.
  3. The work itselfWhat does this service include? — it changes both what is used and how long it takes — and anything found on the day that was not in that is priced before it is started.
  4. Check it togetherCompressor Replacement — it changes both what is used and how long it takes — walked against the written scope rather than against the feeling of it, while the air conditioning engineer is still there.
  5. What you are handedThe itemised invoice and any guarantee on the workmanship and the parts, thermostat Calibration — a small difference here makes a large difference to the total.

What does this service include?

Initial assessment of
Initial assessment of the air conditioning unit.
Repair or replacement

Thermostat Calibration
Adjusting or replacing the thermostat for accurate temperature control.

AFTER

When the job is done

Keep the invoice and the paperworkAn itemised invoice with the trader's name, the work and the total — testing the system — testing the system for proper functionality, because it is what a buyer's solicitor, an insurer or a lender asks for long after the air conditioning engineer has gone.
Test what was doneRepair or replacement — repair or replacement of faulty components — and something that does not work on the day is theirs to put right there and then.
Ask what the guarantee isOn the workmanship and on the parts, and for how long each one runs — they are usually different. initial assessment of — initial assessment of the air conditioning unit — under the Consumer Rights Act 2022 what was agreed is what can be relied on.

Hiring an air conditioning engineer: questions people ask

Repair times can vary based on the issue, but most repairs are completed within a few hours. Check if the air conditioning system is still under warranty.

Repairing your air conditioning can extend its lifespan and improve efficiency, making it a worthwhile investment. Consider the age of the unit when deciding on repairs versus replacement.

While some minor maintenance tasks can be done by homeowners, complex repairs should be handled by professionals. The scope of work can vary based on the type of air conditioning unit, the extent of the damage, and the necessary repairs or replacements required.

NO REGISTER APPLIES TO PLUMBING ITSELF. Anyone may trade as a plumber. The line that does exist is gas: any work on a gas appliance or gas pipework is restricted to the Registered Gas Installer scheme, and a plumber who is not on it may not touch the gas side of a boiler however competent they are at everything else.

Under the Consumer Rights Act 2022 the work must be carried out with reasonable skill and care, and put right if it is not. Say what is wrong in writing first.

Two or three, each for the same written scope. Quotes for different scopes are not comparable, which is how the cheapest one wins and then grows.
