Logan Square sits four to six miles inland from Lake Michigan, which matters more than most people realize. You don’t get the lake’s modest winter buffer or summer cooling relief here. Northwest-side temperatures can run 5-8°F colder on the coldest nights than lakefront neighborhoods like Lincoln Park. That extra heating load, combined with humid summers and aging brick buildings with poor envelope sealing, creates air quality challenges you simply don’t see in newer construction. We know these buildings. We’ve worked on Palmer Boulevard, Kedzie Avenue, and throughout the 60647 zip code for decades.

Our Air Quality & Ventilation team understands the specific problems Logan Square’s housing stock creates. We’ve routed ERV ductwork through shared walls in courtyard buildings, repurposed abandoned octopus furnace trunks as fresh-air chases, and solved humidity problems in basements that were never designed to be sealed living spaces.

ERV/HRV System Installation

In Logan Square’s 1890s-1920s two-flats and greystones, mechanical ventilation isn’t a luxury. It’s often the only way to meet modern air-exchange requirements without opening windows in January. These buildings were built for coal-fired gravity furnaces with zero ductwork. Retrofitting an Energy Recovery Ventilator (ERV) or Heat Recovery Ventilator (HRV) means snaking ductwork through shared walls and plaster ceilings, and frequently dealing with original octopus furnace trunks still buried in basement ceilings.

On a Palmer Boulevard greystone two-flat, we found the owner’s first-floor apartment had stale air and high humidity from a poorly sealed basement and an abandoned octopus furnace trunk blocking airflow. We installed a Daikin ERV system in the basement, repurposing the old trunk as a fresh-air intake chase, and added a whole-house dehumidifier, cutting indoor humidity from 68% to 45% while meeting Chicago’s ventilation code. A typical ERV or HRV installation in Logan Square runs $2,800-$5,500, depending on whether we can repurpose existing chases or need to create new pathways through masonry and horsehair plaster.

Dehumidifier Installation

Logan Square apartments feel humid even with the AC running because cooling equipment in these old buildings is often oversized for sensible heat and undersized for moisture removal. The brick walls and minimal insulation let moisture migrate inward, especially in basement and garden units. A standalone whole-house dehumidifier, properly ducted into your existing system or operating independently, solves what your AC can’t.

We size dehumidifiers for the latent load, not just square footage. In a typical Logan Square two-flat with a damp basement, expect $1,200-$2,400 for a properly installed whole-house unit with drainage and controls.

Ventilation Installation & Ductwork Retrofit

Central ventilation in Logan Square is almost always a custom job. Masonry walls and horsehair-plaster ceilings make it nearly impossible to run central return air ducts in the conventional way. Our crews have developed specific methods for these buildings: using existing chimney flues as vertical chases, routing flexible duct through abandoned plumbing walls, and in some cases installing surface-mounted supply and return systems where concealment isn’t structurally possible.

Shared basement mechanical rooms in courtyard buildings along Logan Boulevard and Kedzie present another challenge. These spaces lack dedicated make-up air for high-capacity range hoods, leading to negative pressure and backdrafting of gas water heaters. We install code-compliant make-up air systems and interlocked ventilation controls. Custom ventilation installations in Logan Square typically range from $2,000-$6,000 depending on the building’s constraints.

UV Air Purifier Installation

For Logan Square homeowners concerned with airborne contaminants in tightly sealed vintage buildings, UV-C air purifiers installed in the ductwork or air handler neutralize mold, bacteria, and viruses. These work best when paired with proper filtration and ventilation, not as a standalone fix. Installation in an existing forced-air system runs $600-$1,400.

Common Air Quality & Ventilation Problems We See in Logan Square Homes

• Abandoned octopus furnace trunks blocking new ductwork. In Logan Square’s two-flats, the original gravity furnaces were routinely abandoned in place when owners upgraded to forced-air in the 1950s-70s. Their oversized trunk arms are still buried in basement ceilings and floor chases. Our crews must either repurpose these massive passages or demo them before new ERV/HRV ductwork can be routed cleanly.
• Pressure imbalances from impossible central returns. Masonry walls and horsehair-plaster ceilings in vintage two-flats make it nearly impossible to run central return air ducts. Without dedicated return pathways, bedrooms pressurize and common areas go negative, pulling garage fumes and basement moisture into living spaces.
• Backdrafting in shared mechanical rooms. Courtyard apartment buildings along Logan Square’s boulevards have basement mechanical rooms designed to be shared across multiple dwelling units. When one unit installs a high-capacity range hood without make-up air, the negative pressure can backdraft gas water heaters, introducing carbon monoxide risks.
• Humidity that AC alone can’t control. Humid Chicago summers create real latent-load problems in buildings with poor envelope sealing, which is nearly universal in Logan Square’s aging brick stock. Contractors who size cooling equipment only for temperature, not moisture removal, leave you clammy even at 72°F.
