Air Conditioning

Air Conditioning

Cooling in summer, warmth in winter — a good air conditioning system does both things efficiently. We install and maintain split, multi-split and VRF systems for residential and commercial spaces.

70% less consumption vs. electric resistance
1 day installation of a typical split
Warranty on installation
  • Complete installation: indoor unit, outdoor unit, piping and cabling — without complex construction work.
  • Trusted brands: we work with Daikin, Mitsubishi, LG and Bosch, depending on your budget and needs.
  • Multi-zone: a single outdoor unit to cool or heat several rooms simultaneously.
  • Installation in commercial spaces: offices, shops and restaurants with higher capacity VRF solutions.
  • Annual maintenance: filter cleaning, gas check and operating report included.

Efficient Heating

Heat Pumps

The heat pump is the most efficient solution for heating or cooling your home. It uses the energy of outside air to produce heat — with electrical consumption up to 4 times lower than traditional systems. Ideal when combined with solar panels.

Dual heats and cools
simultaneously
  • Whole-house air conditioning: central heating and cooling without need for a gas boiler.
  • Hot water: air-to-water heat pumps that replace the electric water heater with major savings.
  • Compatible with underfloor heating: the heat pump is the ideal complement for low-temperature underfloor heating.
  • Grants and incentives: in many cases eligible for energy efficiency programmes with financing.
  • Quiet: the outdoor unit is significantly quieter than generators or boilers.

Underfloor Heating

Underfloor heating warms from bottom to top — the most natural and comfortable way to heat a room. Without radiators on the wall, without draughts, without dust rising. Ideal for new builds or major renovations.

  • Hydraulic or electric: hydraulic underfloor heating (with water) is more efficient; electric is simpler to install in partial renovations.
  • Compatible with all finishes: ceramic, porcelain, engineered wood and natural stone.
  • Silent comfort: no pipe noise or ventilation units. Heating happens imperceptibly.
  • Room-by-room control: each room has its own thermostat — heats only where needed.
  • Perfect with heat pump: operates at low temperature, maximising heat pump efficiency.

🏢

I want to air condition an office or shop

Multi-split air conditioning is the most practical solution: quick to install, easy to control by zone and without construction work.

→ Air Conditioning

I want to replace the gas boiler and lower my bill

The air-to-water heat pump replaces the boiler, heats hot water and still air conditions the house — everything in one system.

→ Heat Pump
🏗️

I'm doing construction or renovation work

Hydraulic underfloor heating is the maximum comfort and efficiency option — it must be installed before finishes.

The most common questions
about air conditioning.

Technically, modern air conditioning is a heat pump — the term "heat pump" is typically used for central systems that replace boilers. A wall-mounted split is ideal for air conditioning one or two rooms; an air-to-water heat pump is ideal for heating the whole house and hot water.
Hydraulic underfloor heating (with water) requires lifting the floor — it must be done as part of construction work. Electric underfloor heating (with cables) can be installed under some types of flooring without heavy work, but it's less efficient. In each case we assess what makes sense during the free visit.
Yes. Modern heat pumps operate efficiently at temperatures down to −15°C. In Lisbon, where temperatures rarely drop below 5°C, performance is excellent throughout the winter.
A 2.5 kW split (sufficient for a 25–30 m² room) consumes about 0.7–0.9 kW of electricity to produce 2.5 kW of cooling or heating — an efficiency 3 to 3.5 times higher than any electric heater. In normal use (6 hours/day in summer), it represents £20–35 per month on your bill.
Installation of a simple split system (one indoor unit + one outdoor unit) takes between 3 and 5 hours. A multi-split system with 2 to 3 indoor units takes 1 full day. We leave the space clean and tested before we leave.
We recommend annual maintenance: filter cleaning, gas charge check and electrical component inspection. This maintenance extends equipment life and maintains energy efficiency. We have an annual maintenance contract available with scheduled visits.
Underfloor heating is an inertia system — it takes longer to reach the desired temperature than air conditioning, but it also maintains heat for much longer after switching off. The solution is to programme the thermostat in advance. With smart controllers (like Nest or Heatmiser), the system learns your schedule automatically.
It's the combination with the highest return on investment. Solar panels generate electricity during the day; the heat pump uses that electricity to heat water or air condition the house. The result is practically free heating during peak solar production hours. We size both systems together.
