Installing a standard bathroom extractor is a single-visit job;, a mechanical ventilation system in a renovation requires duct planning. We leave everything connected, tested, and with the correct intake grilles so the system truly works.

Frequently asked questions

Is annual boiler maintenance mandatory?
Yes, for gas boilers in Spain, it is mandatory by RITE regulations. The inspection includes combustion control, safety valve, and issuing of an official certificate. Without it, the insurer may refuse to cover incidents.
How much does it cost to replace a gas boiler?
400 euros for an installed condensing boiler, depending on brand, power, and necessary work. The replacement typically pays for itself within 4-6 years due to gas savings.
What is aerothermal heating and is it worth it on the Costa Blanca?
It is a heat pump that produces heating, cooling, and domestic hot water with a single appliance. On the Costa Blanca, it performs very well due to the mild temperatures. High initial investment but substantial savings over 8-10 years.
Do you repair old underfloor heating systems?
We diagnose circuits with a thermal camera, detect leaks without breaking the floor when possible, and repair the manifold or valves as appropriate.
Do you work with butane and propane?
Yes, butane and propane boilers are common in areas without natural gas supply. We have technicians authorised for all three types of gas.
Is the quote free?
Yes, free and without obligation. A preliminary visit for diagnosis and proposal. If you don't accept, you pay nothing.
