How do brand and quality tier change the repair cost?
Brand and tier adjust the parts portion only — never labour. Value brands — Cointra, Ferroli, Fagor and Daitsu — carry the cheapest, most widely stocked parts; Baxi (Roca), Junkers Bosch, Saunier Duval and Ariston form the mainstream core of the Spanish boiler market, alongside LG, Samsung, Fujitsu (General) and Haier on the air-conditioning side; premium makers — Vaillant and Viessmann in boilers and air-to-water heat pumps, and Daikin, Panasonic, Hitachi and Mitsubishi Electric in air conditioning and heat pumps — use higher-grade components, often sold through the manufacturer's official channel (piezas de origen). Pick a tier for a class-typical estimate, or a specific Spanish brand to override it.

Air Handler weak airflow: what usually causes it? Estimated
-
Cleaning the indoor unit and replacing the return filters
Pro recommended€120–€200
The filter in the return grille is the great forgotten item in Spanish ducted installations: it gets cleaned once and then years go by. When it blinds over, the airflow drops, the home is not conditioned and the coil ends up icing. A basic clean and sanitising of a ducted unit costs €120 to €200, somewhat more than for a split because of the access at height. The machine is opened in the false ceiling, so the maintenance company does it.
-
Cleaning the duct network
Pro recommended€150–€300
If the machine is clean and the airflow is still low, the problem is downstream: ducts loaded with dust, crushed sections or blocked grilles. Mechanical cleaning of the network is billed by the metre and for homes the figures published in Spain are €200 for a 100 m² flat and €300 for a 150 m² detached house, with a €150 minimum; the much higher figures in those same tables are for offices, shops and whole buildings. It requires rotary brushing and extraction with an absolute filter, equipment belonging to a specialist company.

How much is a service-call fee for air handler repair?
Most Spanish companies charge a call-out / diagnostic fee of €36–€97, often credited toward the repair if you go ahead. It is separate from the repair totals above. Spain's standard 21% VAT (IVA) applies to heating and cooling repair services, and consumer prices are shown VAT-inclusive. A repair carried out in a dwelling can fall to the 10% reduced rate (Spanish VAT Act art. 91.Uno.2.10º) when three conditions hold at once: the customer is a private individual, the dwelling was completed more than two years ago, and the materials supplied by the firm are under 40% of the tax base. Labour-heavy jobs with little material often meet all three, so 21% is the standard rate but not always the effective rate on the invoice — treat it as a ceiling, not a guaranteed add-on.
Is it worth repairing a air handler, or should you replace it?
A common rule of thumb: if the repair cost exceeds roughly half the price of a comparable new unit — or the appliance is past ~8 years for a air handler — replacement is often the better value. The calculator's localized totals give you the number to weigh against a new-unit quote.
