We're new to the valley, and Day and Night is helping us adjust to the unique heating and cooling requirements here. The house we bought has a new HVAC unit, so at this point we're just doing routine checks and making minor corrections to some of the work the original contractor (not Day and Night) did - or didn't do. Like correctly hooking up the Nest device so it actually 'learns' how we heat/cool the house. Philip Brooks is the technician that's been to our house. He's very thorough, explains things in layperson's terms and listens intently to our 'non technical' questions. And he has a wicked sense of humor. We've never felt they were pushing anything on us, and we'll definitely keep working with them moving forward.
