Natural gas costs keep climbing. Older AC units keep losing efficiency. For a lot of homeowners in Ann Arbor, that combination eventually becomes impossible to ignore - and that's exactly where this client was when they reached out to us.
The ask was straightforward: get off gas dependency, handle Michigan winters without a massive electric bill, and do it with a system that's actually built for this climate. Single-digit temperatures are not a hypothetical here. They happen every winter, and a system that folds under that kind of cold is useless.
We went with a pair of Bosch cold-climate air source heat pumps, each rated at 20 SEER2/HSPF2. What makes these units different from a standard heat pump is the operating range. These run at 100% heating capacity down to -5°F. That's not a marketing claim - it's the reason we spec'd them for a Michigan install. The system moves heat rather than generating it by burning fuel, which is a fundamentally more efficient process and a big part of why the energy savings are real.
Beyond performance, this setup is also built ahead of the curve. The 2026 federal energy standards are coming, and this system already meets them. That's not something you have to think about down the road - it's already handled.
For homeowners in the Old West Side, Kerrytown, Burns Park, or anywhere in the Ann Arbor area asking whether a heat pump can actually handle a Michigan winter - this is the answer. The right equipment, sized and installed correctly, makes all the difference.
