Customer Success Stories

Switching to MBtek was one of the best upgrades we’ve made to our home. We were dealing with uneven temperatures, noisy cycling, and a system that always felt like it was working overtime—especially on colder nights. From the first conversation, MBtek helped us understand what was actually happening with our setup and guided us toward the right solution instead of a one-size-fits-all recommendation. The ordering process was straightforward, everything arrived exactly as expected, and the quality of the components was obvious the moment we opened the boxes.

I've been running the TIS EKO 55 all winter and it has been absolutely fantastic. It burns extremely clean, the efficiency is off the charts, and it easily keeps up with the bitter cold. If you want a workhorse for your property, this is it

Heats my home nicely and economically. The cold weather does not seem to affect the pump. Overall I'm very happy with the system. The techs have been very helpful whenever I have had questions regarding installation, etc.

The digital controller right on top is so easy to use—I can monitor the temperature and settings at a glance. It's incredibly well-built, handles the pellets perfectly, and gives me complete peace of mind

I recently got my new Apollo 5-ton air-to-water heat pump installed, and it came out real nice. It's real nice and has a real nice look to it. I am very impressed with the finish of this unit; everything's neat, everything's dressed, it's all clean, painted, airtight, and dry. It's also very quiet. The old unit used to sound like a rocket ship, and this unit is very quiet. I'm very happy with my unit so far. We've gotten down into the 30s, and this thing has no problem keeping up so far. I've noticed the air is hotter, so it doesn't come on for as long, and I'm thinking this is probably making a little hotter water, which is nice.

I purchased a six-ton air-to-water heat pump about three months ago and have been using it this winter. It is doing a great job with the heating system. It complements my existing solar hot water system and gas boiler system. The heat pump does a great job producing the hot water I need for my radiant heat and fan coils. When the unit is running, it is very, very quiet. I can see all the operating parameters on the digital display and through the Wi-Fi app that comes with the unit, which allows me to make any adjustments I need. I look forward to using the unit for summer cooling this year.
