Don't waste your money, go elsewhere
Not at all trustworthy in my opinion, spend a little more for peace of mind vs. wasting your money with them. Worth noting that at least one of the rare positive reviews on here of MBTek, is someone who shares a nationality and unique name with an MBTek employee per LinkedIn. Suspicious. My ERV failed in early August, about 7 months after purchase, a clear defect. It took MBTek 6 days just to admit that in writing. Then support went dark: I called over 20 times, left voicemails (their own message promises a callback within 30 minutes), and got exactly one pickup and one returned call. When they finally responded, they quoted 4-6 weeks for a replacement, meaning 6-8 weeks total with no working ventilation in my home. That same day, MBTek's own website checkout showed 8-35 days for a brand-new order of the identical unit. An existing customer with a defective unit was quoted worse terms than a stranger placing a new order. After I pushed back, a rep verbally agreed on the phone to refund me instead of replacing it. 49 minutes later, I received a written email flatly refusing any refund, citing a policy that contradicted what I'd just been told, addressed to a completely different customer's name, about a different product model. They hadn't even checked whose account they were emailing. I ended up buying the same unit elsewhere for 25% more, just to get working ventilation, because I couldn't trust MBTek to deliver on any timeline they gave me. The hardware might be fine when it works. Their support and warranty process is not something you want to depend on if it doesn't.
