Quick to do nothing; after one week, no follow-up communication.
Built a new home in Central Indiana with Silverthorne. HVAC installer decided to build a smaller "custom" filter box, use an oversized magnet as a cover, and expect a 3\-ton unit to provide adequate heating \& cooling of a 3300+ sq ft home. Contacted their POC over new construction, had an installer arrive the next day with a "larger" magnet. Walked installer through each issue, no follow\-up after 1 week.
