Some companies just do their job. Sumzero really wanted to do it well. They installed heat pumps for my whole house and did everything they could to make sure it was done as well as possible. Really impressed. It started with Rafael. Compared to other sales people who came for estimates, he did not just make an estimate. He put in the extra effort and presented multiple options to find the solution that would work best for us. The rest of the team was the same. When selecting where to place our heat pumps, they discussed location with me and tried to find the best place. After we decided on locations, Marcelo kept thinking about it and actually came with with a really elegant solution. Really happy with the installation and the results.
