What we do
Everything from the first survey to the annual service
One company for the whole job. We survey, specify, supply, install, commission and maintain, so there's no finger-pointing between a fitter and an electrician.
Servicing & maintenance
Annual servicing keeps systems efficient, hygienic and inside warranty terms. Planned maintenance contracts for businesses with multiple units and F-Gas leak-check records.
Servicing detailsRepairs & fault finding
Not cooling, leaking water, tripping the power or flashing an error code? We diagnose quickly and repair any make, with genuine parts where it matters.
Repair detailsElectrical services
Dedicated AC supplies, consumer unit upgrades, EV charger installation, lighting and general electrical work carried out by our own qualified electricians.
Electrical detailsCommercial & office
Offices, retail, restaurants, salons, surgeries and server rooms. Out-of-hours installation to avoid disruption, and maintenance plans with priority call-outs.
Commercial detailsHeating too, not just cooling
Every system we fit is a heat pump. In winter it heats a room at a fraction of the running cost of electric heaters, so it earns its keep all year round.

Customer feedback
What people say after the job
★★★★★“Quoted on the Tuesday, fitted on the Friday. The bedroom unit is whisper quiet and the pipework is hidden so well you'd never know it was there.”
★★★★★“They installed three cassettes in our office over a weekend so we didn't lose a day's trading. Clean, polite and the price matched the quote.”
★★★★★“Our old unit was leaking water down the wall. Aztec found the blocked drain, cleaned the system and it's been faultless since.”
Frequently asked
Questions we get asked most
How much does air conditioning installation cost?
A single wall-mounted unit for a typical bedroom or living room usually costs in the low thousands, fully installed. Multi-room, ducted and commercial systems are quoted after a survey. Every quote is fixed-price and itemised.
Do I need planning permission?
Most domestic outdoor units fall under permitted development, but there are limits on size, location and noise, and flats and listed buildings have extra rules. We'll tell you on the survey if yours needs an application.
Can it heat the room as well?
Yes. Everything we fit is a heat pump that both cools and heats. Heating with a modern split system is typically far cheaper than plug-in electric heaters.
How often should it be serviced?
Once a year for domestic systems, twice a year for commercial units that run all day. An annual service is also a condition of the 2-year warranty.
Do you repair systems you didn't install?
Yes. We repair all major makes, whoever fitted them.
