New Furnace and AC Unit Cost<\/h1>\n\t
\n\t\t
\n\t\t\t

When your furnace and AC are both on their last legs, replacing them together makes sense financially and practically, but the price tag can catch you off guard if you haven’t shopped for HVAC equipment before.<\/p>\n

The new furnace and ac unit cost<\/strong> varies more than most homeowners expect, and quotes from different contractors can swing by thousands of dollars for what looks like the same job, as our 2026 price guide for installing a new HVAC system<\/u><\/a> shows.<\/p>\n

The honest answer is a range, not a single figure: budget $6,000 to $15,000 for most Chicago homes. Three things push a specific quote toward the low or high end: home size, efficiency tier, and ductwork work. However, paying more upfront for higher efficiency usually pays you back. You save in both the heating and cooling seasons through lower monthly bills.<\/p>\n

In this article, we’ll break down realistic price ranges<\/strong> by home size and equipment tier, explain what drives costs up or down, and show you what a fair, transparent quote from a local Chicago contractor should actually include before you sign anything.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

Why furnace and AC replacement costs vary so much<\/h2>\n\t
\n\t\t
\n\t\t\t

Say a homeowner in a 1,800 sq ft two-flat gets three bids for the same combined job: $7,400, $9,900, and $12,200, all pricing comparable equipment for the same square footage. None of those three contractors is lying to you.\u00a0<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t
\n\t\t\t

Instead, the cost for new ac unit and furnace work is a handful of smaller line items stacking up, like ductwork condition, panel capacity, and equipment tier. Moving just one of them can swing the total by a thousand dollars or more.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

Equipment efficiency and brand<\/h3>\n\t
\n\t\t
\n\t\t\t

Manufacturers build furnaces and AC units across a wide efficiency spectrum. As a result, efficiency drives price more than almost anything else. A basic 80% AFUE furnace paired with a 14 SEER2 AC unit sits at the low end.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t
\n\t\t\t

A high-efficiency 96% AFUE furnace matched with an 18+ SEER2 variable-speed AC unit costs considerably more upfront. However, it can cut your energy bills by 20% to 30% a year, according to guidance from the U.S. Department of Energy<\/u><\/a>. Brand name matters too; premium brands with longer warranties and quieter operation carry a higher price than budget-tier equipment.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t
\n\t\t\t

Efficiency ratings, not the size of your house, are usually the single biggest factor separating a $7,000 quote from a $13,000 one.<\/p>\n<\/blockquote>\n\n\t\t<\/div>\n\t<\/div>\n

Ductwork condition and modifications<\/h3>\n\t
\n\t\t
\n\t\t\t

Damaged, undersized, or leaky ductwork adds cost that has nothing to do with the equipment itself. If your existing ducts can’t handle the new airflow, a contractor has to resize, seal, or replace sections before installation. The same applies if you’re switching to a larger unit. This work alone can add $1,000 to $3,000 to a project that otherwise looked straightforward on paper.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Home layout and installation complexity<\/h3>\n\t
\n\t\t
\n\t\t\t

Every house presents different installation challenges. A furnace tucked in an easily accessible basement costs less to swap than one crammed into a tight attic crawlspace or a converted closet, which is why expert furnace installation in Chicago<\/u><\/a> starts with a look at where the unit actually sits. Similarly, if your electrical panel needs upgrading to handle a new high-efficiency system, or if your home lacks a proper condensate drain line, those additions show up as line items on your quote.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n

Timing and demand<\/h3>\n\t
\n\t\t
\n\t\t\t

Lastly, when you schedule the job matters. Contractors in Chicago get slammed during the first cold snap in November and the first heat wave in June. As a result, rushed emergency replacements in peak season sometimes cost more than a planned installation in spring or fall.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>

How to budget for a new furnace and AC installation<\/h2>\n\t
\n\t\t
\n\t\t\t

A combined job is a bigger number than a single-system repair, so it pays to build your budget around real quotes rather than a figure you half-remember from a neighbor’s project. Homeowners who call only one contractor tend to overpay by hundreds or thousands of dollars. They have nothing to measure that number against. Therefore, get at least three written estimates from licensed Chicago-area contractors. Each should break down equipment, labor, and any ductwork or electrical work before you commit.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t

A single quote tells you what one contractor charges; three quotes tell you what the job actually costs.<\/p>\n<\/blockquote>\n

\n\t\t
\n\t\t\t

How you pay matters just as much as what you pay. Many contractors, including Modern HVAC Tech, offer flexible financing for a new HVAC system<\/u><\/a> with payment plans that spread the cost over months instead of forcing a lump sum upfront. Before you commit, check whether your utility company or the state offers rebates for high-efficiency equipment, since these can knock several hundred dollars off your final bill.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t

\n\t\t
\n\t\t\t

Set aside a realistic range rather than a single number, since the average cost of new furnace and ac unit<\/strong> installations shifts based on decisions you haven’t made yet. A practical budgeting checklist looks like this:<\/p>\n\n\t\t<\/div>\n\t<\/div>\n\n\t
