What Ann Arbor weather does to HVAC
Ann Arbor's climate is southeast Michigan standard but the city's dense tree canopy holds summer humidity higher than surrounding areas, and older homes without proper ventilation feel it. Winters are cold enough that the campus-era boiler and radiator homes still make sense, but forced-air retrofits are increasingly common as furnaces age out.
Homes we work on in Ann Arbor
Ann Arbor's housing stock is exceptional in range. Kerrytown, Old West Side, and Burns Park hold hundreds of pre-1920 homes with steam or hot-water heat, retrofitted ductwork, or no cooling at all. Ann Arbor Hills and Scio Township are heavier on 1950s-2000s builds with conventional forced air. We handle both approaches, including ductless mini-splits where full ductwork won't fit.
HVAC problems we see most in Ann Arbor
After years of service calls in and around Ann Arbor, these are the failures we're called out for again and again.
No-duct cooling on historic homes
Old West Side and Kerrytown homes without ductwork are the perfect fit for multi-zone ductless mini-splits. We design and install without disrupting the historic interior.
Aging boiler-plus-window-AC setups
Many Burns Park homes still use a boiler for heat and window units for cooling. Adding a heat pump or ductless system gives real central cooling and a redundant heat source.
Undersized service panels
Older Ann Arbor homes often can't add a new AC or heat pump without electrical panel work. We coordinate with a licensed electrician before quoting equipment.
Commercial RTU end-of-life
Small commercial buildings off State Street and Washtenaw Ave. have RTUs that are 25+ years old. We handle both repair and full replacement, including crane coordination.

Questions Ann Arbor homeowners ask us
Can you install AC in an Ann Arbor historic home without adding visible ductwork?
Yes. Ductless mini-split systems mount high on interior walls and run refrigerant lines through discreet chases. We've done multi-zone installs in Old West Side and Kerrytown homes without touching plaster ceilings.
Do you service commercial HVAC in downtown Ann Arbor?
Yes. Small offices, storefronts, and restaurants near State, Main, and Washtenaw Ave. regularly use us for rooftop unit service, preventive maintenance, and full replacements.
How does your Ann Arbor response time compare to your Howell service?
Ann Arbor is about 40 minutes from our shop, so scheduled service and installations are the same day, but same-hour emergency response is closer to 90 minutes than 30. We're transparent about it.
Are you licensed to work in the City of Ann Arbor?
Yes. We hold MI Mechanical License No. 7119201 and pull City of Ann Arbor mechanical permits routinely for full installs.
Can you add a heat pump to my existing furnace for a dual-fuel Ann Arbor setup?
Yes, and for Ann Arbor's climate a properly sized heat pump plus gas furnace backup is one of the most efficient combinations available. We size, install, and commission the controls to switch fuels at the right outdoor temperature.
