SpacePak high-velocity AC has become a popular option for homeowners who want efficient heating and cooling without the disruption of installing large, conventional duct runs. Instead of bulky ductwork, the system uses smaller, insulated supply lines that can be routed through tight spaces—often making it a better fit for older homes, additions, and ductless-averse households.

At its core, a high-velocity system is built around a central air handler and a set of compact ducting components that distribute air throughout the home. Air is delivered through small-diameter ducts, which can be run through ceilings, closets, soffits, or other constrained areas where standard ductwork would be impractical.

How high-velocity AC works

SpacePak-style systems typically operate by moving air at higher velocities through the smaller ducts. A coil and blower in the air handler condition the air, while the compact distri ... Read more »

Ductless mini-splits and central air both cool homes, but older properties can make the “best” choice look very different. Homes built before modern insulation standards, with leaky ducts—or without ducts at all—often benefit from systems designed for room-by-room comfort.

Below, we compare the two options with an older-home lens: retrofit feasibility, efficiency, comfort, and the tradeoffs homeowners typically weigh before signing a contract.

1) Retrofit reality: ducts (or the lack of them)

Central AC relies on ductwork to move conditioned air throughout the house. In older homes, ducts may be undersized, poorly sealed, routed through unconditioned spaces, or simply not present in the way a new system would need. Fixing or replacing ducts can quickly erase the “lower system price” gap.

Ductless mini-splits avoid most of that. They use an outdoor unit c ... Read more »

Smart thermostats can reduce energy use while making it easier to keep your home comfortable. But with three popular options—Google Nest, ecobee, and Honeywell Home T9—the “best” choice depends on your home layout, preferred app experience, and which smart-home platforms you already use.

This comparison looks at the core differences that affect everyday performance: how each system senses temperature, how well it manages multiple rooms, what automation features you actually get, and what to consider before buying.

1) Sensing and room-by-room comfort

ecobee is often the standout for homes that need multi-room control. Many models include built-in sensors and support additional remote room sensors, which can help heating and cooling respond to where people are—not just where the thermostat is mounted.

Residents along Chicago’s North Shore often notice the telltale signs of hard water: cloudy glass, white scale on faucets, and soap that doesn’t rinse as cleanly. While hard water is not considered unsafe to drink, it can create real headaches for plumbing, appliances, skin, and household cleaning.

What hard water is—and why it happens locally

Hard water contains high levels of dissolved minerals, most commonly calcium and magnesium. In the Chicago area, these minerals can come through natural water sources and affect the local water profile. The result is water that leaves mineral deposits when it evaporates.

For homeowners, the biggest impact is visible: rings around sinks, dull shower doors, and buildup inside showerheads. Over time, scale can also accumulate in pipes and water-using appliances.

How hard water affects your home
