Mission Hills in Franklin, the subdivision of colonials and ranches built in the mid-1970s off St. Martins Road near Chapel Hill Drive, is textbook southeastern Wisconsin housing: solid construction, full basements, mature trees, and mechanical systems that have cycled through two or three generations since the original builds. On Time Heating & Cooling serves Franklin around the clock, and in Mission Hills the work is dominated by end-of-life changeouts, second-floor comfort fixes in the colonials, and duct sealing that should have happened decades ago.
Mid-1970s colonials and ranches, built to last
MLS records put the neighborhood's build years around 1974 to 1976: four-bedroom colonials and three-bedroom brick ranches, most between 1,800 and 2,300 square feet with full basements and attached garages. Mechanical access is excellent, which keeps changeout labor predictable.
Like every subdivision of this era, duct sealing standards were an afterthought. Cloth-taped joints have dried out over 50 years, and sealing during replacement recovers real airflow, especially to colonial second floors and ranch additions.
What goes wrong in Mission Hills homes.
Colonial upstairs delta
One-zone systems leave second-floor bedrooms hot in July and cool in January. Zoning or variable-speed equipment closes the gap.
Original duct joints
1970s tape-sealed joints leak into the basement and joist bays. Sealing at changeout is the cheapest capacity you can buy.
Water heater age stacking
Furnace, AC, and water heater often age together here. Replacing strategically, not reactively, avoids paying three emergency premiums.

Mission Hills HVAC questions.
What systems do Mission Hills homes usually have?
Basement gas furnaces with central AC on trunk-and-branch ductwork, mostly second- or third-generation equipment. The original 1970s installs are long gone, but the original ducts usually remain and benefit from sealing.
Is it worth zoning a 1970s colonial?
If the second floor runs more than a few degrees off the main level, yes. A two-zone damper system with its own thermostat upstairs typically solves it, and it costs far less than oversizing new equipment.
What rebates are live for Franklin in 2026?
