Lynch Heating & Cooling logo LYNCH HEATING & COOLING

Efficient heating and cooling, from one system

An air-to-air heat pump moves heat using refrigerant — warming your rooms in winter and cooling them in summer. It's compact, quick to respond and one of the most energy-efficient ways to keep your home comfortable all year.

System types

Choose the right configuration

Every home is different. We'll help you pick the setup that fits your space, layout and budget.

Outdoor Indoor

Split system

One outdoor unit paired with a single indoor unit, linked by refrigerant pipes. The indoor unit heats or cools the room while the outdoor unit moves the heat.

Best for single rooms, offices or open-plan areas.

Outdoor 2–5 indoors

Multi-split system

One outdoor unit connected to several indoor units. Outdoor units come with 2, 3, 4 or 5 ports, so multiple rooms can be controlled independently.

Best for whole homes with several rooms to climate-control.

Attic unit Outdoor

Ducted / ceiling concealed

The indoor unit is hidden above the ceiling, supplying air through discreet grilles for a clean, modern finish with even distribution and quiet operation.

Best for new builds and premium finishes.

Indoor units

A style to suit every space

Indoor units come in several formats to match your room layout and finish.

Cassette

Fitted into suspended ceilings, distributing air in four directions. Ideal for offices and open areas.

Highwall

The most common wall-mounted option — perfect for homes, bedrooms and living spaces.

Floor mount

Installed low on the wall near floor level — ideal where wall or ceiling space is limited.

Under ceiling

Mounted directly beneath the ceiling — well suited to shops, large rooms or areas without a ceiling void.

Why air to air

The advantages

Cost-effective, efficient and comfortable — here's why air-to-air is such a popular choice.

01

Lower installation cost

No radiators, underfloor pipework or hot water cylinder required — making it a more affordable route to comfort than air-to-water.

02

Cleaner indoor air

Built-in filters capture dust, pollen and particles as air circulates. Many units add allergen, deodorising and anti-bacterial filtration.

03

Fast, responsive heating

Warm air flows directly into the room, heating it quickly — far faster than solid fuel or radiator-based systems.

04

Heating & cooling in one

Warm in winter, cool in summer — year-round climate control from a single compact system, ideal for changeable Irish weather.

05

High energy efficiency

Heat is transferred, not generated — delivering several units of heat for every unit of electricity used, keeping running costs low.

06

Ideal for retrofits

Often fitted with minimal disruption — no need to tear up floors for pipework, making it a practical upgrade for older homes.
