CRG Direct supplies, installs, and services air conditioning units across Hampshire - from single wall-mounted units for a bedroom or home office to multi-split systems covering an entire house, and commercial air conditioning for offices, retail spaces, and larger commercial environments.
Most installations take one to two days. All systems are A++ energy rated.
What We Install
Wall-mounted split systems are the most common choice for individual rooms. A single outdoor unit connects to one indoor unit, giving you heating and cooling with individual room control. Quick to install, quiet in operation, and cost-effective for one or two rooms.
Multi-split systems connect multiple indoor units to a single outdoor unit. Each room gets its own temperature control, making them more efficient than running several separate units. The right choice for whole-house climate control without ducting.
Ducted systems route conditioned air through concealed ceiling or floor vents, keeping your interior design intact. Temperature distributes evenly throughout the property. Best suited to new builds or major renovations.
Commercial VRF systems use variable refrigerant flow technology to serve large buildings efficiently, with simultaneous heating and cooling across different zones.
Heating, Cooling, and Air Quality
Modern air conditioning does more than cool rooms during hot spells. The same system provides efficient heating throughout winter - air conditioning units operating as heat pumps are among the most energy-efficient heating systems available.
Most modern units include integrated filtration that removes dust, pollen, and allergens from indoor air. Combined with controlled ventilation, the result is better air quality year-round. Latest models run at near-silent levels during normal operation.
Energy Efficiency
All systems we supply carry an A++ energy rating. A well-sized air conditioning unit in heating mode can deliver three to four units of heat for every unit of electricity it uses. That efficiency directly reduces energy bills, particularly during winter months.
Annual servicing maintains that efficiency over time. We offer annual servicing contracts across Hampshire.
Our Installation Process
Site survey. An engineer visits your property, assesses the space, and discusses your requirements. We size the system correctly for your room or building.
System design. We specify the right unit or units for your space, plan the installation route, and confirm the price before any work begins.
Installation. Our certified engineers carry out the full installation, typically in one to two days.
Commissioning. We test the full system, set up smart controls and scheduling, and walk you through operation.
Commercial Air Conditioning
We work with businesses across Hampshire - offices, retail spaces, and larger commercial environments. Our commercial installations include building management system integration where required, so you can monitor and control energy usage across zones.
