Heating and Ventilation Sligo Leitrim
Heat pumps, underfloor heating and insulation in Sligo and Leitrim
Green Air Technologies provides modern heating and ventilation solutions for homeowners who want a warmer, healthier and more energy efficient home. This category page brings together our main heating and ventilation services for properties across Sligo and nearby parts of Leitrim.
Heating accounts for the largest share of energy use in most Irish homes. Getting the heating and ventilation strategy right is often the most effective step a homeowner can take to reduce bills, improve comfort and lower the carbon footprint of the property.
The challenge is that no two homes are the same. An older stone cottage on the Sligo coast near Rosses Point has very different needs to a 1990s semi on the edge of Sligo Town or a new build in a Leitrim village. Wall construction, floor type, ceiling height, existing pipework and household size all influence what system will perform best.
With 25 years of experience serving homeowners across Sligo and the North West, our approach begins with understanding the property properly. We carry out a heat loss assessment before recommending any system, helping ensure that whatever is installed is correctly sized and configured for the actual demand. An oversized heat pump running inefficiently or an underfloor system placed on a poorly insulated floor slab will not deliver the results it should.
As approved and recommended SEAI and NSAI registered contractors, we install and commission complete heating and ventilation systems for new builds, deep retrofits and targeted upgrades across Sligo, Leitrim and surrounding counties. Every installation is carried out by trained and ‘qualified’ engineers and every system is commissioned properly before handover to you, with annual servicing available to help keep performance on track, if you need us.
Our heating and ventilation services
Heat pumps
Air source heat pumps are now the main heating solution for new residential builds in Ireland and are increasingly a promising option for older homes as insulation standards improve. Rather than generating heat by burning fuel, a heat pump extracts heat from the outside air and upgrades it to a useful indoor temperature.
A well specified good quality heat pump can deliver high efficiency when matched to the particular property correctly. Combined with Solar Panels PV and suitable electricity tariffs, the running cost advantage over oil or solid fuel can become increasingly attractive.
For homes across Sligo and Leitrim that have traditionally relied on oil boilers or solid fuel stoves, the move to a heat pump becomes much more practical when the right insulation measures are in place first. This is where a whole house approach matters, especially when Attic Insulation, Cavity Insulation or External Insulation are part of the wider plan.
We install heat pumps for:
new build residential properties
deep retrofits where insulation upgrades support the transition
properties replacing older oil or solid fuel heating systems
Our heat pump installations can cover:
air to water heat pumps for Irish domestic use
full integration with Underfloor or low temperature radiators
hot water cylinder installation and configuration
controls and smart thermostat setup
support with SEAI Grants and certification
Every heat pump we install is supplied with manufacturer warranties and backed by our long term service commitment. We will not touch low quality cheap products with no warranties. Homeowners who want a deeper overview can also visit the dedicated Heat Pumps service page.
Underfloor heating
Underfloor heating is a natural partner for heat pump technology. While traditional radiators often need much higher water temperatures, underfloor heating works effectively at lower temperatures, which suits the way heat pumps perform best.
The result is a system that warms the room evenly from the floor up, reduces cold spots and helps support lower running costs when designed properly. In homes across Sligo and Leitrim, where winters can feel damp and sharp, that steady warmth can make a noticeable difference to day to day comfort.
We install both wet and electric underfloor heating systems depending on the project:
wet underfloor heating is usually the preferred option for new builds and larger retrofits where the floor is being lifted or a new screed is being laid
electric underfloor heating can suit smaller areas where a wet system would be less practical, such as bathrooms or certain extensions
Our underfloor heating installations include:
full system design and pipe layout
manifold installation and balancing
screed depth and thermal mass recommendations
zone controls for room by room management
commissioning and handover
Underfloor heating is also a popular choice for home extensions, helping homeowners gain even warmth without taking up wall space with extra radiators. For more detailed information, see our Underfloor service page.
Heat recovery ventilation
Modern airtight homes need planned ventilation. When a home is built or upgraded to a higher airtightness standard, the natural draughts that once replaced stale air are reduced. Without a proper system, moisture, indoor pollutants and stale air can build up and lead to condensation and comfort problems.
Mechanical ventilation with heat recovery (MVHR) helps solve that by continuously extracting stale air from wet rooms and supplying fresh filtered air to the main living spaces and bedrooms. The heat exchanger inside the unit recovers warmth from the outgoing air and transfers it to the incoming air, helping maintain comfort without unnecessary heat loss.
In our North West climate, where moisture levels can stay high for much of the year, (too much) a properly functioning system can play an important role in controlling condensation and supporting healthier indoor air. Homes near Strandhill, Enniscrone or inland parts of Leitrim can all benefit from more consistent controlled airflow. MVHR is a requirement under Part F of the Irish Building Regulations for new builds achieving a certain level of airtightness, and is increasingly specified as part of deep retrofits.
Our Heat Recovery service can include:
full system design including duct layout and unit sizing
commissioning and airflow balancing
filter maintenance guidance and servicing support
retrofit options for suitable existing properties
External insulation
External wall insulation is one of the most effective upgrades available for older solid wall homes. Across Sligo and Leitrim, many older properties were built with solid walls and no cavity, which means the practical insulation options are often external or internal. External insulation is usually preferred because it protects internal space, reduces disruption inside the home and wraps the building more completely.
External insulation involves fixing insulation board to the outside of the wall and finishing it with a reinforced render system. In a region where driving rain is common from autumn into spring, the added weather protection can be valuable as well as the thermal improvement.
Benefits can include:
reduced heat loss through walls
less cold bridging at junctions
improved airtightness when detailed correctlybetter protection of the existing wall structure
better protection of the existing wall structure
improved appearance and BER performance
SEAI support may be available for eligible homes and we help manage the process from survey to installation and grant related paperwork. Homeowners comparing options can explore the dedicated External Insulation page for more details.
Cavity insulation
Homes built in Ireland from the mid twentieth century onwards often have cavity walls. Filling a suitable cavity with insulation can be one of the more cost effective upgrades available, with relatively modest disruption and a fairly quick return in reduced heating demand.
Cavity insulation is installed through small drilled holes in the outer wall and the finish is then made good. The process is generally quick and clean, but the wall must be suitable first. Homes with damp issues, narrow cavities or very exposed conditions need careful assessment before any recommendation is made. Otherwise you could be wasting money.
That is why we carry out a proper survey before moving forward, in line with current standards. You can read more on our Cavity Insulation service page.
Attic insulation
Heat rises, so in a poorly insulated home a large share of the heat generated by the heating system can escape through the roof. Attic insulation remains one of the highest value upgrades available because it is comparatively straightforward to install and the comfort benefit can be felt quickly. Like wearing a cap.
For accessible pitched roofs, we install insulation between and above the joists to help achieve the required thermal standard. For flat roofs or more complex structures, we review the best approach on a case by case basis.
Attic insulation also plays an important part in wider retrofit planning. Improving the roof reduces the workload on the heating system, which in turn supports better performance from measures such as Heat Pumps. Many older homes across Sligo and Leitrim still have much less insulation than current guidance would suggest, so this can be a sensible early step. More detail is available on our Attic Insulation page.

Heating and Ventilation Frequently Asked Questions
Is a heat pump suitable for an older rural home in Sligo or Leitrim?
Heat pumps work best in homes with controlled heat loss. Older rural homes, especially those with solid walls or older construction methods, often benefit from some insulation improvement first. We carry out a full heat loss assessment and advise on what upgrades may be needed before moving to a heat pump. Not every pump is ideally suited to every house.
What is the difference between heat recovery ventilation and a standard extractor fan?
A standard extractor fan usually serves a single room and removes stale air without recovering heat. You are basically creating heat and then throwing it away. Heat recovery ventilation is a whole house system that extracts from multiple rooms or sources, supplies fresh filtered air and helps retain warmth through the heat exchange process. You get to keep all your heat.
How much can I save with attic and cavity wall insulation?
Savings depend on the current condition of the home, its size and how it is heated. In many cases, improving attic insulation and adding suitable cavity insulation can reduce heating demand noticeably. An accurate estimate depends on a proper assessment of the property.
Do underfloor heating systems work with existing boilers as well as heat pumps?
Yes. Underfloor heating can work with existing boilers, but the efficiency gains are usually enhanced when paired with a heat pump because the system performs well at lower temperatures. And the technology is always improving.
What grants are available for insulation and heating upgrades in Sligo and Leitrim?
SEAI grants may be available for measures such as attic insulation, cavity insulation, external insulation, heat pumps and other qualifying upgrades. Applications must be made before work begins and the installer must be appropriately registered. We help manage that process for eligible clients.
