Why Fireside Heating & Air Co. of Chicago Is Highwood’s Preferred AC Repair & Installation Company
Highwood sits in a narrow strip between Highland Park and the lake, easy to miss on a map but impossible to service well without knowing its two distinct housing stocks. We’ve spent four decades working on both: the modest pre-war bungalows built for Fort Sheridan laborers, and the thick-walled 1890s military buildings converted to residences in the late 1990s. That split experience matters when your system fails on a humid July afternoon.
Our phones are answered by a live person 24 hours a day, 7 days a week - no voicemail tree, no offshore call center. When a Highwood caller reaches us at 2 a.m. with a dead compressor, we dispatch. Most repairs are completed in one visit because our trucks carry parts for the nine major brands we service: Lennox, Goodman, Rheem, York, Carrier, Trane, Daikin, Bryant, and American Standard.
Every job carries our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork for you to chase down, no argument about whether the problem is “related.” Terry Kowalski built this company on that standard starting in 1984, and we still apply it to every AC Repair & Installation in Highwood.
Our technicians are background-checked, uniformed journeymen who put on shoe covers without being asked. They treat your home the way they would their own mother’s. That’s not a slogan on a truck. It’s how we hire and how we train.
Our AC Repair & Installation Services in Highwood
AC Repair
Highwood’s lakefront position means outdoor coils face near-constant high humidity and salt-laden moisture. We’ve replaced compressors that failed in six years when they should have lasted fifteen. We replaced a failed compressor on a 20-year-old Goodman unit at a Fort Sheridan condo on Martin Lane, where the original 1890s brick walls forced us to surface-mount the refrigerant lines inside a custom chase to comply with code and maintain the historic aesthetic. Typical AC repair in Highwood runs $150-$650. We diagnose first, quote upfront, and the price we state is the price you pay.

AC Installation
New system installation in Highwood demands different approaches depending on which side of the city you’re in. The worker cottages near the Metra tracks often need ductwork upgrades or mini-split solutions because original steam or hot-water systems left no chase for cooling. The Fort Sheridan condos require careful zoning to handle irregular floor plans and 12-16 inch solid brick walls with no cavity. AC installation in Highwood ranges from $3,500 to $7,500. We measure, we calculate Manual J load, and we explain why one approach fits your specific house before we quote.

AC Replacement
When repair costs approach half the value of a new system, we give straight talk about replace versus repair. In Highwood, we factor in the corrosion damage from lake-effect exposure - a unit that’s rusting through its cabinet at year eight may not be worth another major repair. We carry Lennox, Goodman, Rheem, and York systems suited to humid, corrosive conditions, sized correctly for your home’s actual load, not its square footage alone.

Refrigerant Recharge
Low refrigerant in Highwood often signals a leak caused by coil corrosion from lake-driven moisture. We don’t just top off and leave. We pressure-test, locate the leak, and show you where it failed. If your system uses R-22, we’ll explain your options honestly - recharge with reclaimed refrigerant, retrofit, or replace - with costs for each path.

Capacitor Replacement
Capacitors fail faster in Highwood’s humidity. It’s a common summer call. We stock dual-run and single capacitors for all major brands, and most replacements take under an hour. If the capacitor failed because your compressor is drawing high amps, we’ll tell you that too, before you spend money on a symptom instead of the cause.

Compressor Repair
Compressor repair in Highwood ranges from $350 to $1,200. Lake-effect corrosion often attacks the electrical connections and contactors first, causing hard-start conditions that burn out the compressor motor. We test amp draw, check for acid in the refrigerant, and determine whether the compressor is salvageable or if replacement makes more sense. In the Fort Sheridan buildings, compressor swaps require careful handling of line sets routed through interior chases - work we’ve done many times.

Trusted Brands We Service in Highwood
We train our technicians on nine major residential brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Highwood customers, we stock capacitors, contactors, and coils for Goodman and Rheem systems - two brands we see frequently in the area’s older housing stock - plus Lennox and York parts for newer installations. That local inventory means faster turnaround. Most Highwood repair calls don’t wait for a parts run to Highland Park or Northbrook. We arrive with what we need.
Common AC Repair & Installation Problems We See in Highwood Homes
- Lake-effect coil corrosion. Highwood’s position directly on Lake Michigan exposes outdoor condensing units to salt-laden moisture that accelerates coil and cabinet corrosion faster than units even a few miles inland. We see refrigerant leaks in 5-7 years that take 12-15 elsewhere, often leading to premature compressor failure.
- Undersized ductwork in pre-war bungalows. The worker cottages and bungalows throughout Highwood’s core were built with heating-only systems. Original ductwork, where it exists at all, cannot handle modern AC airflow. The result is frozen evaporator coils, short cycling, and rooms that never cool properly.
- Surface-mounted line sets in Fort Sheridan condos. The converted Army post buildings have 12-16 inch solid brick walls with no cavity. Refrigerant lines and condensate drains must run through interior chases or surface-mounted channels. We’ve routed dozens of these installations, each one unique to the unit’s layout and the building’s historic preservation requirements.
- High humidity strain on electrical components. Near-constant high relative humidity in summer corrodes contactors, capacitors, and control boards faster than drier inland climates. We inspect these components carefully on every service call because they fail in clusters once deterioration starts.

FAQs - AC Repair & Installation in Highwood
Highwood sits directly on Lake Michigan’s western shore, while Highland Park is set back slightly inland. That proximity exposes Highwood condensing units to persistent salt-laden moisture and higher relative humidity, accelerating coil and cabinet corrosion by several years compared to even a few miles west. We specify corrosion-resistant coatings and more frequent maintenance for lakefront properties. Call (833) 983-1671 to schedule - our $89 seasonal tune-up catches corrosion early.
Yes, but it requires custom planning. The original 1890s Army-post exterior walls are 12-16 inches of solid brick with no cavity, so refrigerant line sets and condensate drains must be surface-mounted or run through interior chases. We’ve completed many such installations in the Fort Sheridan conversion properties, working within historic preservation guidelines and local code. Each building presents a unique routing challenge. Call (833) 983-1671 for a free on-site evaluation and written estimate.
Yes, often through a ductless mini-split system or high-velocity small-duct retrofit. The worker cottages throughout Highwood’s core were built with steam or hot-water radiator heat that left no infrastructure for cooling. We’ve installed mini-split systems in dozens of these homes, mounting compact air handlers on walls or ceilings and running refrigerant lines through slim exterior channels. No plaster demolition required. Call (833) 983-1671 - we’ll walk your house and show you exactly where units would go.
Twice yearly: once in spring before cooling season, and once in fall to inspect for corrosion damage after summer humidity exposure. The lake-effect moisture that accelerates corrosion also breeds mold and algae in condensate drains. Our $89 seasonal tune-up includes coil cleaning, refrigerant level check, electrical component inspection, and drain clearing. For Highwood properties within two blocks of the lake, we recommend the spring visit no later than mid-May. Call (833) 983-1671 to book.
We specify coated coils and corrosion-resistant cabinets from Lennox, Goodman, Rheem, and York for Highwood installations. These manufacturers offer coastal-grade protection options that standard inland models lack. The right unit for your home depends on your specific building type - bungalow versus Fort Sheridan condo - and your existing ductwork or lack thereof. We don’t push one brand. We match the equipment to your house and your budget. Call (833) 983-1671 for a free second opinion if you’ve received another estimate.
