Why Fireside Heating & Air Co. of Chicago Is Highwood’s Preferred Heat Pump & Mini Split Company
We’ve worked in Highwood since the Fort Sheridan conversion began in the late 1990s. That’s long enough to know which condos on Leonard Wood Avenue have the original 1890s brick walls, and which cottages on Green Bay Road still run on steam heat with no ductwork. That history matters when you’re deciding between repairing a 20-year-old heat pump or starting fresh with a multi-zone mini-split.
Our phones are answered by a live person 24 hours a day, 7 days a week, including holidays. When a heat pump fails on a January night and the temperature’s dropping through the floor, Highwood residents need Emergency & Commercial HVAC in Highwood - not a voicemail tree.

Our Heat Pump & Mini Split Services in Highwood
Heat Pump Repair
Highwood’s lake-effect humidity corrodes outdoor coils faster than almost anywhere in Lake County. We see it constantly on Sheridan Road properties facing the water: condenser fins deteriorated, contactors pitted, refrigerant leaking from vibration-chafed lines. AC Repair & Installation in Highwood for heat pumps runs $150-$650 depending on whether we’re replacing a reversing valve, patching a leak, or swapping a compressor. We stock common parts for Carrier, Trane, Lennox, and Goodman so we’re not ordering and waiting.
Heat Pump Installation
Many of Highwood’s 1920s worker cottages on Green Bay Road and Lewis Avenue were built with Heating & Furnace in Highwood systems using steam or hot-water heat and no ductwork. Installing a traditional heat pump with air handler and duct retrofit can cost more than the house is worth to some owners. That’s why we often recommend ductless mini-splits or high-velocity systems for these properties. Heat pump installation in Highwood ranges $3,500-$7,500. We’ll give you straight talk about repair versus replace, and we’ll never sell you equipment your house can’t use efficiently.
Mini Split Install
This is where Highwood gets interesting. The Fort Sheridan historic district - those 1890s-1910s Holabird & Roche brick buildings converted to residences - presents a challenge no neighboring city’s techs regularly face. The exterior walls are 12-16 inches of solid brick with no cavity. You can’t run refrigerant lines through them. You can’t hide condensate drains. Every line set must be surface-mounted on the historic facade or routed through interior chases, which means coordination with HOA aesthetic rules and local code enforcement. Mini split installation in Highwood runs $3,500-$7,500, but the labor estimate for a Fort Sheridan condo will look different than for a 1950s ranch in Deerfield. We’ve done enough of them to know the questions to ask before we quote.
Mini Split Repair
Multi-zone mini-splits are popular in Highwood’s smaller cottages and Fort Sheridan units because they solve the no-ductwork problem elegantly. When they fail, it’s usually a refrigerant leak at the flare connection, a failed inverter board, or a clogged condensate pump. We repair all major brands, and we carry replacement heads and outdoor units for systems we installed. If your mini-split is icing up, short cycling, or blowing warm on one head and cold on another, we’ll diagnose it honestly and tell you whether a $200 repair makes sense or if the system’s reached replacement age.
Multi-Zone System Design
Fort Sheridan condos with high ceilings and irregular floor plans often need three or four zones to maintain even temperatures. Original steam radiators were removed in many units, but no zoning was added, which means top floors bake while lower levels stay cold. We design multi-zone Daikin and Carrier systems that account for solar gain on south-facing brick walls and stack effect in multi-story units. It’s not a catalog order. It’s a site-specific plan, and we’ve written enough of them for 60040 addresses to know the building patterns.

Trusted Brands We Service in Highwood
Our trucks carry parts and equipment for nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Highwood’s coastal corrosion environment, we often recommend Carrier or Daikin outdoor units with enhanced cabinet coatings, and we’ve had strong results with Lennox variable-capacity systems in the Fort Sheridan properties where precise load matching matters. We don’t push one brand because we get a spiff. We match the equipment to the house, the budget, and the expectation. Parts are stocked locally, so most Highwood repairs don’t wait on shipping.
Common Heat Pump & Mini Split Problems We See in Highwood Homes
- Corroded condenser coils from lake-effect humidity. Outdoor units on Sheridan Road and facing properties absorb salt-laden, high-humidity air year-round. We see coil deterioration in 8-10 years that might take 15 inland. Annual tune-ups catch it early.
- Refrigerant leaks from unprotected line sets in thick masonry. When copper lines run through or against 12-inch solid brick without proper grommeting, vibration slowly chafes holes. We find this in Fort Sheridan conversions where original installers cut corners on penetration sealing.
- Short cycling from stuck reversing valves. Lake moisture corrodes valve solenoids and causes electrical faults. In a 1905 cottage on Lewis Avenue, we found a 20-year-old Carrier heat pump that had corroded from lake-moisture exposure and was short cycling on a stuck reversing valve. We replaced it with a new Daikin mini-split, running the line set through an interior closet chase to avoid penetrating the 12-inch brick.
- Inadequate cooling in upper Fort Sheridan zones. Original steam radiators were removed but no zoning added. Heat rises in those high-ceilinged brick spaces and has nowhere to go. A single-head mini-split on the main floor won’t fix it. We add upper-zone cassettes or wall mounts with dedicated outdoor ports.

FAQs - Heat Pump & Mini Split in Highwood
Yes, we install mini-splits in Fort Sheridan condos regularly, but the method differs from standard construction. Because the 1890s exterior walls are 12-16 inches of solid brick with no cavity, refrigerant lines and condensate drains must run through interior chases or be surface-mounted with code-approved protection. We’ve developed routing plans for most Fort Sheridan building types, and we coordinate with HOA architectural committees on visible line placement. Call (833) 983-1671 for a free assessment of your specific unit.
Yes, a heat pump can absolutely work in your bungalow, but it will be a ductless mini-split or high-velocity system rather than a conventional ducted heat pump. Highwood’s worker cottages were built for steam heat, and retrofitting full ductwork is often impractical and invasive. We install multi-zone mini-splits that provide heating and cooling without tearing into plaster walls. Most Green Bay Road bungalows need two to three zones. Call (833) 983-1671 and we’ll walk through your layout.
Modern cold-climate heat pumps operate efficiently down to well below zero, which covers all but the most extreme Highwood winter events. The lake-effect snow and moisture don’t reduce efficiency directly, but they do demand proper outdoor unit placement and defrost controls. We spec systems with enhanced defrost logic and elevated mounting to shed heavy snow. For the coldest January nights, many Highwood homeowners keep a small backup heat source, which we can integrate. Call (833) 983-1671 to discuss your comfort preferences.
Icing can be caused by lake-effect snow blocking airflow, but it’s more often a refrigerant charge issue, a failing defrost board, or restricted airflow from dirty coils. Highwood’s humidity accelerates coil fouling, and we’ve found many Goodman units with defrost sensors corroded from salt air exposure. We’ll diagnose the actual cause rather than blame the weather. If your unit is over 12 years old and icing repeatedly, replacement may be more economical than chasing intermittent faults. Call (833) 983-1671 for a free second opinion.
Most Highwood worker cottage mini-split installs take one to two days for a two-zone system. Single-zone jobs on an exterior wall with easy electrical access can finish in a day. Factors that extend timing: fishing lines through finished interiors, upgrading electrical panels, or adding refrigerant line-hide for aesthetic concealment. Fort Sheridan condos with interior chase routing typically need two days. We quote timeline along with price, and we don’t leave until the system is running and you’ve been shown the controls. Call (833) 983-1671 to schedule.
