Report
My house only had an 80-year old floor furnace (and no AC capability) so I wanted a complete HVAC upgrade. My friends recommended Sandium. Ended up having them install an efficient Carrier heat pump (Infinity 24), attic air handler, and all new attic ductwork. Marcos, Carlos, & Pat did a really solid and thorough installation job (HERS leakage numbers are almost negligible). And the company was very responsive in sending Martin to correct some issues afterwards. Mike (the estimator & co-owner) is a no-nonsense, no-pressure engineer kind of guy who laid out different approaches/costs and then left it for me to decide.
That was a little confusing at first as I was more used to salesmany types who tried to sense what I wanted/needed and then guide me toward that. So I had to do my research. But I ended up with a solid system that I understand better.

Outstanding service. I needed service a sap to get air conditioner working and new Nest Thermostat installed. Contracor came out and checked the AC, corrected our incorrect Nest assembly and installed it so that it works. He was fast and very friendly, just couldn't have been nicer and more accommodating. He also called to say due to traffic he would be 20 minutes delayed, which was really considerate.

Nik Morokutti is one of the most capable and honest people I have ever worked with. Nik helped us provisioned and built Air Source Heat Pump system for heating and cooling in our Palo Alto house. He answered tons of detailed questions from us and carried out the work professionally. We are extremely happy with the result. Nik and his people went beyond our wildest expectations. He is our model of an engineer (and we know a lot of engineers!)

Perhaps a bit more expensive than others, but absolutely worth the cost. We had Sandium install two systems in our two-storey house. The attention to detail in planning the design, the workmanship, communication and final result are all top-notch. Strongly recommended.
