Air conditioner and boiler comparison: installed prices in Barcelona

Here they are, in a single comparison tool: every air conditioner, boiler and water heater we install in Barcelona, with their installed price including VAT and the figures that actually matter when choosing: capacity, room size, SEER and SCOP efficiency, indoor and outdoor noise, annual consumption, dimensions, Wi-Fi and refrigerant. Every figure comes from the official datasheets and price lists of Mitsubishi Electric, Daikin, Bosch, Junkers Bosch, Vaillant and Saunier Duval, not from a sales brochure.

Filter by room size, type or brand, sort by price, efficiency or quietness, and tick up to three models to see them side by side, figure by figure. Each model links to its product page with the installed price.

How to read the figures: SEER, SCOP, decibels and kilowatts

Capacity and room size. For air conditioning, the cooling kW set the area a unit can handle: about 2.5 kW for a room of up to 15 m², 3.5 kW for 15-25 m², 4.2 kW for 25-35 m², 5 kW for 35-45 m² and 7 kW for living rooms of 55-65 m². If the room faces south, has a lot of glass or is a top-floor flat, go one size up. These are the ranges we use in the catalogue and in the air conditioning installation cost guide. For boilers, the heating kW depend on the size and insulation of the flat, and the hot-water kW on how many bathrooms run at the same time.

SEER and SCOP. These are the seasonal efficiencies from the EU energy label: how much cooling (SEER) or heating (SCOP) a unit delivers per kWh of electricity over a season. From a SEER of 8.5 upwards we are talking class A+++. The SCOP on the label is for the average climate zone; the comparison also shows the warm-climate SCOP, which is the one that applies to Barcelona and is usually a good deal better. Between two units of the same size, the annual consumption in kWh published by the manufacturer is the most direct way to see the difference on the bill.

Noise. The indoor-unit figure in quiet mode (19-22 dB) is the one that matters in a bedroom. The outdoor-unit figure is the one to check if it faces an inner courtyard or a balcony with neighbours close by: Barcelona’s by-law limits outdoor noise, and sound power Lw is the value used to check it.

2×1 multi-split. In a 2×1 system, the capacity and efficiency of the whole are set by the outdoor unit, not by adding up the two indoor units. That is why the comparison shows the outdoor unit’s figures (MXZ-2F42VF, MXZ-2F53VF, MXZ-2HA40VF or MXZ-2HA50VF) and, for reference, the sum of the indoor units.

Boilers. All the boilers we install are class A combi condensing boilers on natural gas. Look at the minimum modulation (the lower, the better it suits a small, well-insulated flat), the hot-water flow in litres per minute and the NOx emissions. If you are torn between repairing and replacing, the guide when to replace your boiler explains it with figures.

What the installed price includes

The prices in the comparison are those of our catalogue: unit, VAT and standard installation in Barcelona and its metropolitan area, carried out by our own certified technicians. For air conditioning, standard installation covers up to 3 metres of pipework, brackets, drain and commissioning; for boilers, removal of the old one, connection to gas, water and electricity, room-sealed flue and commissioning. We only install equipment we supply ourselves, so we answer for the whole job. If your case needs extra pipework, building work or a special flue, we tell you in writing in the quote before we start.

Frequently asked questions about the comparison tool

Which is the most efficient air conditioner in the catalogue? By SEER, the Daikin Perfera TXM20A and TXM25A (9.47) and the Mitsubishi Electric MSZ-EF, followed by the MSZ-AY series (8.7). For heating in Barcelona, look at the warm-climate SCOP: the Perfera reaches 6.39 and the MSZ-AY50 6.1. You can sort the table by efficiency with one click.

Which is the quietest? The Daikin Perfera and the Mitsubishi Electric MSZ-EF and MSZ-AY go down to 19 dB(A) in quiet mode on the indoor unit. Outdoors, the Mitsubishi Electric MSZ-AY and the 2×1 MXZ-2F42VF outdoor units stay at 44-45 dB(A).

What is the difference between a Daikin Sensira and a Perfera? The Sensira is the entry range: A++ efficiency (SEER 6.5) and a simple air filter. The Perfera is A+++ (SEER up to 9.47), has a presence sensor and a Flash Streamer filter, and uses considerably less electricity a year. The price difference pays for itself in a few summers if the unit is used daily.

Which boiler do I need for a flat with one bathroom? With one bathroom and up to about 90 m², a boiler with 24 kW for hot water is enough: the Junkers Bosch GC1200 W 20/24 or the Condens 4300i W 24/25. With two bathrooms that may run at the same time, go up to 28-32 kW for hot water, such as the Condens 6000 W 25/28 or 25/32. The boiler installation page has a table by type of home.

Do the prices include installation and VAT? Yes. All prices in the comparison and the catalogue include the unit, standard installation and VAT. There are no hidden costs: if the installation needs anything extra, you will see it itemised in the quote before you accept.

Where do the technical figures come from? From the official datasheets, manuals and price lists of each manufacturer (Mitsubishi Electric, Daikin, Bosch, Junkers Bosch, Vaillant and Saunier Duval), checked model by model. Where a manufacturer does not publish a figure, the cell shows a dash rather than an estimate.
