Why Highwood Homeowners Choose Fireside Heating & Air Co. of Chicago
Highwood is a small city with outsized HVAC challenges. We’ve earned our place here by showing up prepared for both worlds: the modest bungalows near the Metra tracks and the converted Fort Sheridan officer’s quarters with their 16-inch solid brick walls.
Our technicians have worked in homes along Sheridan Road, Green Bay Road, and throughout the Fort Sheridan historic district. They know which cottage basements have the headroom for a new air handler and which Fort Sheridan condos need surface-mounted line sets because drilling through Army-post masonry is not an option. That familiarity saves you time and keeps the job from growing.
We are licensed and insured, background-checked, and trained as journeymen. Our home base is in Chicago, but Highwood is not an afterthought for us. Most repairs are completed in a single visit because our trucks carry parts for nine major brands: Lennox, Goodman, Rheem, York, and five others. The price we quote is the price you pay. And everything we do is backed by our 90-Day Done Right Promise - in writing, no paperwork, no arguing.
HVAC Services We Offer in Highwood
AC Repair & Installation in Highwood
Lake Michigan humidity hits Highwood harder than inland Lake County. Corroded condenser coils, failing capacitors, and low refrigerant are the calls we answer most often each summer. We repair all makes and models, and when replacement makes more sense, we size the system for your actual home - not a rule-of-thumb calculation.

Heating & Furnace in Highwood
Many Highwood bungalows still run original steam or hot-water systems, while Fort Sheridan conversions rely on forced air retrofitted into spaces never meant for ductwork. We service boilers, furnaces, and hybrid setups, and we’ll give you straight talk about repair versus replace.

Heat Pump & Mini Split in Highwood
For homes without existing ductwork - common in both the worker cottages and the Fort Sheridan masonry buildings - ductless mini-splits offer zoning without tearing apart walls. We design and install systems that handle Highwood’s temperature swings without the backup heat running constantly.

Why Highwood’s Climate & Housing Affect HVAC
Highwood’s position directly on Lake Michigan’s western shore creates conditions you will not find even three miles west in Highland Park, IL or Northbrook. The near-constant high relative humidity rolls off the water and settles on outdoor condensing units, corroding coils and cabinets faster than almost anywhere else in the Chicago metro. We replace condensers in Highwood that inland techs would expect to last another five years. Lake-effect snow squalls add another variable: heavy, wet snow can bury a heat pump or block a vent intake in minutes while the rest of Lake County stays clear.
The housing stock compounds these climate stresses. Highwood’s core neighborhoods were built for laborers serving Fort Sheridan and the North Shore estates - modest bungalows and cottages with aging, often undersized duct systems or no ductwork at all. Original steam and hot-water radiator heat is common, which complicates cooling retrofits because there is no existing air distribution path. Then there is the Fort Sheridan conversion properties: 1890s to 1910s Holabird & Roche-designed masonry buildings, 12 to 16 inches of solid brick with no wall cavity, converted to residences in the late 1990s. Retrofitting modern HVAC into those structures requires surface-mounted refrigerant lines, interior chases for ductwork, and custom zoning to handle irregular floor plans and high ceilings. It is specialized work that repeats building after building throughout that development, and it is unlike anything else in the 60040 ZIP.

FAQs About HVAC in Highwood
Most AC repairs in Highwood run between $200 and $750, depending on the part and the accessibility. Corroded coastal condensers and capacitors stressed by humidity are the most common calls we see here. Call (833) 983-1671 for an exact quote - estimates are free.
Yes, though it usually requires a ductless mini-split or high-velocity system rather than traditional ductwork. Many Highwood cottages lack the basement headroom or wall cavities for conventional ducts. We will walk you through the options that fit your specific layout.
Those 1890s masonry walls were built for barracks, not residential zoning. The thick brick, high ceilings, and irregular floor plans create natural temperature stratification. We typically solve this with a multi-zone mini-split or a carefully balanced duct retrofit - never a single thermostat trying to guess at three different spaces.
If your furnace is over 15 years old and the repair approaches 40% of replacement cost, replacement is usually the better value. In Highwood’s lakefront environment, we also factor in whether corrosion has compromised the heat exchanger - a safety issue that ends the repair conversation. We will give you straight talk, not a sales pitch.

What Highwood Customers Say
"The thermostat had been miswired by whoever installed it, so the heat strips were running with the AC. He found it in a few minutes and probably saved me a fortune on the next few bills."
- Nicole Fletcher"Blower motor on a twelve year old furnace. He gave me the honest math on repair against replace and did not push me toward the bigger ticket."
- Paige Hoffman"The maintenance plan is actually worth it. They turn up twice a year and the last visit caught a refrigerant leak before it became a July disaster."
- Kurt Anderson
