Air Conditioning Installation in Gloucestershire
PBT Installations design, install, service and maintain air conditioning systems for homes and businesses across Gloucestershire — from Cheltenham and Gloucester out to the Cotswolds and the Forest of Dean. Our F-gas certified installers handle everything from a single room to a whole-property system, and because we’re an MCS-accredited renewables company first, we look at cooling as part of how your whole home uses energy — not just a box bolted to a wall.
Air conditioning that works all year round
A modern air conditioning unit isn’t only for the handful of hot weeks each summer. The same system cools your rooms in July and runs as an efficient air-source heat pump in the colder months, delivering economical warmth when you need it. For many Gloucestershire homes, that makes air conditioning one of the most versatile comfort upgrades you can fit — particularly in garden rooms, loft conversions, home offices and south-facing extensions that overheat.
Air conditioning also quietly improves the air you breathe. Built-in filtration captures dust and allergens, and the dehumidifying effect helps slow the reproduction of dust mites — a real benefit for anyone in the household with allergies or asthma.
Where air conditioning makes sense

We install air conditioning across both domestic and commercial properties in Gloucestershire, including:
- Home offices and garden rooms — keep a workspace comfortable without heating the whole house
- Bedrooms and loft conversions — sleep through summer heatwaves
- Extensions and conservatories — tame the rooms your existing heating can’t reach
- Shops, cafés and commercial units — keep customers and staff comfortable, and stock protected
Whether you need a single split system or a multi-room setup with one outdoor unit serving several indoor heads, we’ll size and position the system around how you actually use the space.
CASE STUDY
We installed a Toshiba split system unit with a wall mounted internal unit to circulate air flow, and a discreet exterior unit positioned out of view. The customer is very happy with the product and can work comfortably year round.
A customer located in Cheltenham approached us looking for a way to heat his home office. The office space was at the bottom of the garden, away from the house and was heated with oil filled and electric portable heaters. The office was cold in winter and hot in summer and the customer was wearing thermal layers through colder months. The cost of raising the temperature in the office through heating was high with little impact made.
Cooling as part of a whole-home system
This is where we differ from a standard air conditioning company. PBT Installations are heat pump and renewables specialists, so we can tell you honestly when air conditioning is the right answer — and when a heat pump that already cools, or a ducted system, would serve you better.
Many of the Stiebel Eltron heat pumps we install can cool rooms as well as heat your home and hot water, which means some properties don’t need separate air conditioning at all. And for new builds or major renovations, our Invisible.AC small-duct (SDHV) systems deliver heating, cooling, ventilation and air purification through one discreet, integrated system. If you’re weighing up the options, we’ll give you a straight comparison rather than simply selling you a unit.

Using heat pumps can reduce carbon use and make homes more energy and cost efficient
F-gas certified installation across Gloucestershire
Air conditioning systems use refrigerant gases that are regulated by law, so installation, servicing and repair must be carried out by F-gas certified engineers. Our installers are fully F-gas trained, and as an MCS-accredited, NAPIT-registered and TrustMark-endorsed company, we install to standards you can rely on.
We currently fit Toshiba air conditioning units — well-priced, reliable, and backed by excellent manufacturer support — and we service and maintain systems for customers right across the county.
We cover Cheltenham, Gloucester, Cirencester, Stroud, Tewkesbury, the Cotswolds, the Forest of Dean and the surrounding Gloucestershire area.
Frequently Asked Questions
In most cases, no — external units are usually classed as permitted development on a standard house. There are some limits (unit size, distance from boundaries, and stricter rules if you’re in a conservation area or a flat), so if your property falls into any of those categories, we’ll check this with you as part of the consultation rather than assume.
Quieter than most people expect. Modern outdoor units are designed to run at low decibel levels, and we position them carefully — away from bedroom windows and neighbouring boundaries where possible — to keep any noise unnoticeable in everyday use.
A single-room split system is often completed in a day. Larger or multi-room setups take longer depending on complexity — we’ll give you a clear timeframe once we’ve assessed your property.
Yes — as F-gas certified engineers, we carry out servicing and maintenance to keep your system running efficiently and compliant with the regulations covering refrigerant gases, not just the initial installation.
