Highland Park HVAC Replacement Guide (2026)

Highland Park spans a wider range of housing than almost any town on the North Shore, and that variety shapes the HVAC work here. Grand older homes fill Ravinia and the lakefront, while postwar and newer construction stretches inland through neighborhoods like Sherwood Forest and West Highland Park. The result is a city where replacement projects run the full spectrum: boiler modernization in the historic core, matched furnace-and-AC systems in postwar neighborhoods, and a growing number of heat pump installs where homeowners want efficiency and rebates. This guide covers how to think about a replacement across that range.

A city of many housing ages

Because Highland Park's homes span more than a century of construction, there is no single "typical" system here:

• Historic Ravinia and lakefront homes often run steam or hot-water boilers and radiators, many decades old, with no existing ductwork.
• Postwar and mid-century homes inland run forced-air furnaces and central air, frequently aging out together.
• Newer inland homes are candidates for efficiency upgrades, including heat pump installation for the utility rebates.

Identifying which era your home belongs to is the first step, because it determines both the equipment and the kind of installer experience the job calls for.

The heat pump opportunity

Highland Park sees more interest in heat pumps than many North Shore towns, partly because inland homes are well suited to them and partly because of the incentives. A modern cold-climate heat pump heats and cools from a single electric system and is increasingly practical for Chicago-area winters, often paired with a gas furnace as a dual-fuel setup that uses the furnace on the coldest days.

The real draw is the rebate. ComEd offers a tonnage-tiered rebate in the $1,400 to $2,000 range for qualifying cold-climate heat pumps, which meaningfully offsets the cost. Equipment has to meet cold-climate performance standards and be installed by an eligible trade ally to qualify, so the paperwork matters. Our heat pump cost and rebates in Illinois guide covers the full picture, and heat pump versus furnace in the Chicago climate gives an honest look at where each wins.

For historic and forced-air homes

Not every Highland Park home is a heat pump candidate. In historic Ravinia homes on radiators, careful furnace replacement is not the right frame at all; those are boiler projects, often paired with ductless cooling for summer. In postwar forced-air homes, the classic project is a matched furnace-and-AC full system, right-sized to the home with a proper load calculation rather than copied from the old equipment. A good installer will tell you honestly which path, gas furnace, dual-fuel heat pump, or boiler, actually fits your home rather than pushing whatever carries the biggest rebate.

What it costs

As planning ranges on the North Shore:

• Furnace replacement typically runs $4,500 to $9,000, central AC $4,000 to $8,000.
• A matched furnace-and-AC full system runs $9,000 to $18,000.
• Boiler replacement runs $7,000 to $15,000.
• Heat pump installation runs $10,000 to $22,000 before rebates.

Where you land depends on your home's size, age, and system type. These are starting points; the only accurate figure comes from a written, in-home estimate.

Rebates worth checking

For 2026, the incentives that remain are the utility programs:

• ComEd offers the $1,400 to $2,000 tonnage-tiered heat pump rebate for qualifying cold-climate equipment.
• Nicor Gas offers roughly $225 for a qualifying 97% AFUE furnace and up to about $100 for a qualifying smart thermostat.

Amounts change, and Highland Park sits in Lake County where utility service can vary, so confirm your electric and gas providers and their current programs before you buy. Our ComEd and Nicor rebates guide explains how to actually claim them.

Timing your replacement

Replace heating in early fall and cooling in early spring when you can. Off-season scheduling is calmer, avoids the emergency premium, and gives you time to choose qualifying equipment and file the rebate paperwork properly, which matters most for heat pump projects where trade-ally rules apply.

Putting it together

Highland Park's range of housing means the right replacement is genuinely home-specific: a heat pump upgrade with a strong ComEd rebate for the right inland home, a matched full system for a postwar house, or careful boiler work with ductless cooling for a historic Ravinia home. Work with a licensed, insured installer who assesses your actual home and steers you toward the equipment and rebates that fit, not the biggest ticket.
