Jeff, the owner/operator at Cypress, is like an HVAC genius. I consulted seven companies because I had very specific outcomes I wanted in replacing my furnace and adding a/c. Ultimately, I went with Cypress because Jeff obviously put by far the most thought into how to set up the best possible system for my family's needs. He spent about 3X more time than anyone else assessing the situation, and quickly followed up by email and phone to answer the series of questions I had and explain all the theory behind his recommendations.
When the time came for the install, Jeff came when we promised and everything went just like he said it would. He also kept us updated on progress over the multiple day installation and was always really thoughtful about noise and disruptions to our days (working from home). Most importantly, he did really careful work - even prompting a compliment from the gas inspector who said that he didn't see many installs done as nicely these days.
Overall, Jeff is a really nice guy who knows a tonne about furnaces and is super easy to deal with. Whether you have a complicated situation that requires a specific solution, or just want someone honest, knowledgable, and reliable, I would definitely recommend giving Cypress a call.
