Zelsia Instalaciones

We're very happy with the work Zelsia did installing an air source heat pump for our pre-installed underfloor heating. Since we were renovating the apartment, they quickly made room for us to ensure the underfloor heating was working properly before replacing the flooring. They also provided a cover for the unit while we had time to install a wardrobe. They proactively resolved any minor issues that arose. And especially noteworthy is the fact that the unit was installed in August, and we didn't move in until November to test it. The unit wasn't working correctly initially, but they themselves

I completely renovated my house, and companies from all trades came in. Without a doubt, Zelsia was the best. Despite air conditioning being one of the most delicate aspects, we couldn't be happier with the result—a perfect installation. I wouldn't trust any other company and I highly recommend them. I should also mention that whenever I've had a problem, they've always responded very quickly.

An unparalleled team of professionals, speed and unbeatable service. I recommend this company without hesitation. Thank you for your work.

This summer I had a Mitsubishi 3x1 air conditioner installed, and the sales staff and installation technicians are truly excellent professionals. They also deliver on time. Highly recommended.

Many thanks to the entire Zelsia team for their outstanding professionalism and the wonderful personal attention we received during the consultation and installation of our photovoltaic panels. It's a pleasure working with companies like this. The results are impressive.
