Everything that's covered — and everything that isn't.

If you use your air conditioning seasonally — a few weeks of summer and the occasional cold snap — AC Essential is enough. If it runs most of the year, you rely on it for sleep or work, or it's in a shop or office, AC Complete is worth it for the second visit alone: problems get caught in October rather than during the first heatwave. Any business premises, or a system with five or more indoor units, needs the commercial route so every unit is actually covered.

The plan price covers your first indoor unit. Each additional one is £3.99 a month + VAT on AC Essential or £5.99 a month + VAT on AC Complete. So a house with three indoor units on Complete is £16.99 + £5.99 + £5.99 = £28.97 a month + VAT. Every unit is cleaned and checked on every visit, and you get one report covering all of them. Plans go up to four indoor units; beyond that, or for any VRV/VRF or commercial system, a surveyed contract usually works out better and we'll tell you so.

Because each one is a separate job. Every indoor unit has its own filters to clean or replace, its own coil and fan to clean, its own condensate drain to clear and prove, and its own controls to test. A three-unit system takes roughly twice as long on site as a single one. We'd rather charge for the time honestly than quote one price and then service one unit properly and glance at the other two.

The full service is the complete checklist above — strip down, deep clean, every test. The performance check before winter is shorter and targeted: filters, condensate drain, electronic leak check, controls, and a run in heating mode with the temperature split measured. It's there to catch anything that's drifted since the summer and make sure the system is ready for the season it's about to work hardest in. It isn't a second full service, and we don't pretend it is.

No. Most systems we look after were installed by somebody else. The first visit includes a full condition survey so you know exactly what you've got and what state it's in — including anything the original installer didn't do properly. We're approved service partners for Daikin, Mitsubishi, Fujitsu, Samsung, Hisense, Midea and Bosch, and our F-Gas registered engineers service every other major brand.

Call us. Plan holders pay a reduced call-out fee of £69 + VAT rather than the standard £89 + VAT, and go to the front of the queue. That fee covers getting an engineer to you, the first hour on site, and diagnosing the fault. If the job runs beyond the first hour it's charged at the same rate — £69 an hour for plan holders, £89 an hour otherwise — and we'll tell you before the clock goes past the hour, not afterwards. Parts and any return visit are quoted separately, with 10% off on Essential or 15% off on Complete.

The call-out fee covers the visit and the first hour on site. After that it's the same figure per hour — £89 standard, £69 if you're on a care plan — charged in half-hour blocks, not rounded up to the next full hour. Most faults are diagnosed and either fixed or quoted inside that first hour. If it's going to run over, the engineer tells you what's involved and what it will cost before carrying on.

In most cases yes — many manufacturers require documented annual servicing as a condition of the warranty, which is exactly what the written report gives you. Check your own paperwork, because terms vary by brand, and tell us if there's a specific requirement to meet.

Plans run for 12 months and you can move up a tier at any point during that. If you've booked a one-off service you can put it towards a plan afterwards — just ask when you book.
