How to choose a commercial air conditioning contractor
Questions to ask before hiring an air conditioning contractor: F-gas certification, what the quote includes, warranties, programme and aftercare.
Short answer
Check F-gas company and engineer certification, get a written specification with the make, model, capacity, refrigerant and everything included, confirm who handles electrics, condensate, access and paperwork, and agree servicing so the manufacturer warranty stays valid.
Questions to ask
- What is your F-gas company certificate number, and which engineers will handle refrigerant?
- What make, model and capacity are you quoting, and which refrigerant?
- Does the price include electrics, condensate pumps, access equipment and making good?
- How long will installation take and can you work out of hours?
- What commissioning records and F-gas paperwork will we receive?
- What warranty applies and what servicing does it require?
Red flags
- No survey before quoting a multi-unit job
- No unit make or model on the quote
- Re-gassing without finding the leak
- Offers to install without consent where it is clearly needed
