While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more

To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience.

A Lifesaver During the Deep Freeze!"

A Lifesaver During the Deep Freeze!"

As a new homeowner, I was naturally nervous about how our heating system would handle its first full winter. After a year of use, I couldn't be more impressed. Even throughout the recent extreme cold snap, the system kept our entire house at a perfectly consistent, comfortable temperature.
What I appreciate most is how user-friendly the controls are—it took no time at all to learn. Additionally, our energy bills have been surprisingly manageable, which speaks to its efficiency. To top it off, the customer care team has been fantastic and responsive whenever I had questions. Highly recommend for any new homeowner looking for peace of mind!
