UK Specialists in Air Conditioning Without Outdoor Units & Conservatory Climate Control
OUR SPECIALIST SERVICES

Thoughtful Air Conditioning Solutions for Modern Homes.

Explore discreet systems designed to provide comfortable indoor temperatures without traditional external condenser units.

Air Conditioning Without an External Unit

Traditional split air conditioning requires an outdoor condenser unit, connected to indoor units by refrigerant pipework. Split systems also mean you cant cool one room whilst heating another, Our units work independently of each other offering Total Flexibility.

Our self-contained integrated systems incorporate the cooling and heating mechanisms inside a single sleek indoor casing. On the outside wall, two circular core vents (typically 162mm or 200mm diameter, depending on the model) are fitted with discreet exterior grilles.

KEY TECHNICAL & AESTHETIC ADVANTAGES:

  • ✓ Zero Exterior Condenser: No bulky metal box spoiling your patio or garden.
  • ✓ No Unsightly Trunking: No plastic trunking carrying refrigerant lines across external facades.
  • ✓ Year-Round Heat Pump: Suitable heating and cooling models can provide comfort across the seasons.
  • ✓ Leasehold & Conservation Friendly: A discreet alternative where external units are restricted, subject to property permissions.

Year-Round Usability: The right climate control system can help make your conservatory more comfortable in both summer and winter.

CONSERVATORY SPECIALISM

Conservatory Air Conditioning

Conservatories are beloved for their natural light and panoramic garden views, but their extensive glass surfaces present significant thermal challenges throughout the British year.

Summer Solar Gain

Solar radiation passes through glazing, creating intense temperatures that can make the room uncomfortable during hot summer afternoons.

Winter Heat Loss

Extensive glazing can allow heat to escape quickly, meaning standard central heating may struggle to maintain comfortable temperatures during colder months.

Our conservatory climate control solutions are selected to suit the changing temperatures of glazed structures. Where appropriate, low-wall Integrated units can be mounted onto suitable dwarf masonry walls, providing cooling during summer and heat pump warmth in winter.

VERSATILE APPLICATIONS

Other Suitable Living Spaces

Self-contained climate control provides elegant solutions across a wide variety of residential rooms where traditional condensers are impractical.

Garden Rooms

Standalone cedar or composite garden buildings often overheat rapidly under summer sunshine. Suitable integrated systems can provide both cooling and supplementary winter heating.

Flats & Apartments

Leaseholders frequently face restrictions on external condenser units. Internal Integrated systems requiring discreet wall vents may offer a practical alternative, subject to building permissions.

Home Offices

Maintain a more comfortable working environment with discreet climate control. Suitable cooling systems can help reduce discomfort caused by stuffy, overheated rooms.

Bedrooms & Lofts

Attic conversions and south-facing master bedrooms can trap intense roof heat. Discreet climate control helps create more comfortable sleeping conditions during warm summer nights.

* Note: Property suitability varies depending on wall depth, cavity materials, and external airflow clearance.

FACTUAL COMPARISON

Why Consider a System Without an Outdoor Condenser?

An objective look at how self-contained Integrated systems compare with traditional split systems.

Feature / Consideration Integrated System (No Outdoor Unit) Traditional Split System
External Appearance Two small flush wall vents (typically 162mm or 200mm, depending on the model). No external condenser box or bulky outdoor ducting. Requires an outdoor condenser unit, typically installed on an exterior wall, patio slab, balcony or other suitable location, together with external pipework and casing.
Pipework & Trunking No external refrigerant pipework connecting separate indoor and outdoor units. The main refrigeration components remain inside the self-contained unit. Refrigerant pipework connects indoor and outdoor units, requiring external casing and trunking along the building facade.
Leasehold & Planning Suitability A practical alternative where outdoor condenser units are restricted. Wall vents can still require landlord, freeholder or planning approval. Outdoor equipment may be restricted by leasehold agreements, conservation requirements or planning conditions.
Installation Considerations Typically requires two external core openings through a suitable perimeter wall, together with appropriate electrical connections and condensate management. Requires suitable outdoor mounting, refrigerant pipework, electrical connections and installation by appropriately qualified F-gas engineers.
Survey Requirements Climate Select's approximately 90-minute property survey assesses wall construction, room size, glazing and suitable airflow paths. No Survey Undertaken. Typical assessment based on room size, pipework routes and cheap models.
Environmental Considerations Our Integrated systems feature factory-sealed refrigerant circuits, eliminating the need for external refrigerant pipework connections between separate indoor and outdoor units. Traditional split systems use refrigerants that can have an environmental impact if released. Refrigerant leaks can occur at external pipework joints and connections, particularly if damaged or incorrectly installed.

CLEAR ANSWERS

Frequently Asked Questions

Honest, transparent guidance regarding our systems, suitability, and installation processes.

Do these air conditioning systems need an outdoor unit?

No. Our specialist Integrated internal systems do not require the bulky outdoor condenser box or external refrigerant pipework typical of conventional split systems. Instead, the complete refrigeration cycle is housed inside the single indoor unit.

The system connects to the outside via two discreet core-drilled wall vents (typically 162mm or 200mm diameter, depending on the model), fitted with subtle weather grilles.

Can air conditioning be fitted in a conservatory?

Yes. Conservatories are one of our specialist areas. Their extensive glazing can cause significant heat gain in summer and heat loss in winter.

We assess the room's size, glazing, insulation and wall construction before recommending a suitable system. Where appropriate, an Integrated unit can be installed on a suitable external-facing dwarf wall.

Can the systems heat as well as cool?

Yes. Many of our integrated systems incorporate heat pump technology, allowing them to provide cooling during warmer months and heating when temperatures drop.

The suitability of a system as a primary or supplementary heating source depends on the property's insulation, room size and the equipment's heating capacity.

Are the systems suitable for flats and apartments?

They can be an excellent alternative for properties where traditional outdoor condenser units are impractical or restricted.

However, an external-facing wall is still required for ventilation. Leaseholders should also confirm whether permission is required from their freeholder or management company before any installation work.

Can I install the equipment myself?

We offer supply-only options for customers who are competent in Diy or who already have an experienced tradesperson available.

Installation involves accurately drilling through an external wall, securing the unit, fitting ventilation grilles and making appropriate electrical and drainage arrangements.

All work must follow the manufacturer's instructions and applicable safety requirements. Professional installation is recommended where specialist work is needed.

What happens during a home survey?

Our detailed property survey typically takes around 90 minutes. Richard will assess the room dimensions, glazing, insulation, wall construction, available electrical supply and potential installation locations.

This helps us establish which system is suitable for your property and explain the available options before you make a decision.

How much does an installation cost?

Costs vary depending on the system selected, room requirements, wall construction and installation complexity.

We aim to provide clear information about the available options and associated costs before any work begins. Contact Richard to discuss your property and arrange a suitability assessment.

How do I find out which system suits my property?

The best starting point is a conversation about your property, how you use the room and the heating or cooling challenges you experience.

Richard can talk through your options and arrange a detailed survey to identify a suitable system for your specific requirements.

Maintenance Advantages

Integrated systems are housed indoors, protecting the main unit from direct exposure to external weather conditions. Each unit operates independently, meaning an issue with one unit does not necessarily affect others. With no external condenser or interconnecting refrigerant pipework, maintenance requirements can be simpler, although routine cleaning and servicing are still recommended.

Traditional split systems require regular maintenance to maintain performance and identify potential refrigerant leaks. External condenser units are exposed to weather conditions and may experience corrosion or discolouration over time. Refrigerant pipework requires appropriate insulation. In multi-room systems sharing one outdoor condenser, a failure of that condenser can affect all connected indoor units.
