Picking a system is the big decision
When you replace heating or cooling equipment, you're not just buying a box — you're choosing how your home stays comfortable for the next 15 to 20 years. The right system controls temperature, humidity, and air quality together, and it's sized to your house. Midland has installed and serviced every system type below in Twin Cities homes since 1950, so here's the simple, no-jargon version of your options.
Gas furnaces
The most common heating system in Minnesota. A gas furnace burns natural gas and uses a blower to push warm air through your ducts. Furnaces deliver high-temperature heat reliably on the coldest nights, which is why they remain the backbone of Twin Cities heating. Efficiency is measured in AFUE — see our efficiency ratings guide — and a modern high-efficiency furnace converts roughly 90–98% of its fuel to heat.
Central air conditioning
A central air conditioner pairs an outdoor condenser with an indoor coil to move heat out of your home, with cooling efficiency rated in SEER2 (and EER2 for peak conditions). The single biggest factor in comfort and bills isn't the brand — it's correct sizing. An oversized AC cools so fast it never removes humidity, leaving the house cool but clammy.
Heat pumps (including cold-climate models)
A heat pump both heats and cools with one system by moving heat instead of burning fuel. Today's cold-climate heat pumps keep heating well below 0°F — a real change from older models. They're highly efficient in the shoulder seasons; you can learn the fundamentals in What Is a Heat Pump? In deep cold, most Minnesota homes pair a heat pump with gas backup — which brings us to dual-fuel.
Dual-fuel / hybrid systems (often the best fit here)
A dual-fuel system combines an electric heat pump with a gas furnace, and the control automatically runs whichever fuel is more economical at a given outdoor temperature: the heat pump for efficient heating most of the year, the furnace on the coldest stretches. For many existing Twin Cities homes this is the configuration Midland most often recommends — efficiency without giving up dependable heat at –15°F.

Ductless mini-splits
Ductless mini-splits are heat pumps that condition specific rooms without ductwork, using an outdoor unit and one or more indoor heads. They're ideal for additions, finished basements, garages, and the hot-or-cold rooms ductwork never reached — quiet, zoned, and efficient.
Boilers, hydronic & radiant heat
Plenty of older St. Louis Park and Minneapolis homes are heated by a boiler that circulates hot water or steam through radiators or in-floor loops instead of blowing hot air. Hydronic heat is comfortable and even; it needs a different skill set to service, and a home with a boiler typically adds cooling with central AC or ductless mini-splits.
Geothermal
A geothermal heat pump exchanges heat with the stable temperature of the earth rather than the outdoor air, which makes it very efficient even on extreme days. It's a larger upfront investment with ground loops, and utility incentive programs may help offset the cost — see rebates & incentives.
Packaged & commercial systems
When indoor mechanical space is tight, a packaged unit puts all the components in one cabinet, usually on the roof or a slab — common for light commercial buildings and some homes. Midland services rooftop units and design-build systems for Twin Cities businesses.
Smart controls & indoor air quality
Modern systems pair with smart thermostats and whole-home indoor air quality equipment — high-efficiency filtration, humidifiers, and ventilation — to manage comfort, humidity, and air quality together, not just temperature. In a tightly sealed Minnesota home, that pairing matters.
Which system is right for your home?
The honest answer depends on your current equipment, ductwork, fuel access, budget, and how long you'll stay. There's no single "best" system — only the best fit for your house, confirmed with a load calculation rather than a guess. Midland installs all of the above, so the recommendation isn't tied to selling one product.
