I ordered a fairly budget ventilation project and was pleasantly surprised by the attentive attitude, offered several options at once, explained what would happen and how, everything was done on time. Prices are reasonable again, maybe you can find cheaper, but I'm afraid that they would not offer everything with delivery and installation, and even engineers only in specialized companies. Who needs not just to buy something in an online store, but to make everything beautifully a good option.
We bought a heater here in the fall, but it was warm and we started turning it on just now. We took a more expensive model than the 2 kW score was supposed to be, so that it would certainly be warm in the apartment, although at first we wanted an Atlantic. There was no point in ordering delivery, because we live across the street, so I personally came to buy it, at the same time immediately on the spot and checked how warm it was. After a week of frost, I can say that this is our salvation, but I will probably be afraid to look at the electricity bill))
It's been a month since we received a wonderful Patent fan delivered home from the Alter Air store. I was very impressed with the design and appearance. And there are no noise characteristics at all. As for me, it's a great option for your money. there are no complaints or comments about the company. I'm happy with everything!
