Why local actually matters here

Local HVAC service for Aurora homes.

Aurora is Illinois' second-most populous city, founded in 1834 along the Fox River and formally organized in 1857 — which means a genuinely wide age range of housing stock in one metro area, from homes built before 1900 downtown to postwar subdivisions to new construction on the outer edges.

The Fox River splits the city into an East Side and West Side, and like any river-adjacent housing, homes closer to it tend to run more humid in summer than the subdivisions further out — one of the first things worth checking when a system is running but the house still feels sticky.

Aurora has four locally designated historic districts — Near Eastside, Riddle Highlands, Tanner, and Palace Street — plus the West Side Historic District, and the Downtown Aurora neighborhood alone has more pre-1939 housing than 97.5% of neighborhoods nationwide. That's exactly the kind of housing stock where matching a new system to the old unit's label instead of running a real Manual J load calculation causes the most problems.

What that actually means for your system

Common HVAC Problems We See in Aurora Homes

Aurora's housing stock runs from pre-1900 homes downtown to new construction on the outer edges, and Downtown Aurora alone has more pre-1939 housing than 97.5% of neighborhoods nationwide — exactly the kind of stock where matching a new system to the old unit's label instead of running a real Manual J causes short-cycling and early wear. The Fox River splitting the East and West Sides adds a second variable: homes closer to it tend to run more humid through summer than those further out. We treat age and humidity as two separate questions, not one guess.

What we handle in Aurora

Everything FortHouse does, available to Aurora homeowners directly — not routed through a regional dispatcher two counties over.

AC repair & AC maintenance

Same-day AC repair when the air stops running cold, and AC maintenance that accounts for the extra humidity homes on either side of the Fox River deal with — static pressure, refrigerant charge, amp draw, not just a filter swap.

Furnace repair & heating maintenance

Furnace repair and gas furnace repair with a combustion safety check on every visit, across a housing stock that ranges from pre-1900 homes downtown to new construction on Aurora's outer edges.

HVAC installation & replacement

Full HVAC installation and replacement, Manual J–sized rather than matched to the old label — Downtown Aurora alone has more pre-1939 housing than 97.5% of neighborhoods nationwide, and an oversized system in an older, less-sealed house short-cycles and wears out early.

Ductless mini-split installation

Ductless AC installation and mini-split installation for additions and rooms in Aurora's older east-side neighborhoods that have no practical path to extend existing ductwork.

How much does AC repair cost in Aurora, IL?

Most AC repairs run $150–$600, with the specific part setting the price — a capacitor costs far less to replace than a compressor. Given how much Aurora's housing stock varies in age, from pre-1900 downtown homes to new construction on the outer edges, we diagnose first and write the quote off what we actually find.

How much does furnace repair cost in Aurora, IL?

Furnace repairs land in that same $150–$600 range, with the cost set by the part — a flame sensor is quick to swap, an inducer motor is a bigger job. Every visit includes a combustion safety check at no extra cost, with the quote written before any repair starts.

Do you do furnace maintenance in Aurora?

Yes — a 21-point fall tune-up for $119, including the heat exchanger, burner, carbon monoxide, and safety controls, with the readings written on the invoice. Book it before the first cold snap, when the service calendar fills with no-heat calls.

How much does furnace replacement cost in Aurora?

$5,000–$9,000 installed: about $5,000–$7,000 for a standard 80% AFUE furnace and $6,300–$9,000 for a 95%+ high-efficiency unit. Most swaps take one day, with sizing, the City of Aurora permit, and old-unit removal included.

Do you install ductless mini-splits in Aurora?

Yes — single and multi-zone systems for additions, garages, and rooms without existing ductwork. We handle line-set routing and condensate planning as part of the install, which comes up often given how much of Aurora's older housing stock has no practical path to extend ductwork into new spaces.

See ductless mini-split installation details
Does Aurora's older housing stock need anything different for HVAC work?

Often, yes. Homes in Aurora's historic districts and older east-side neighborhoods weren't built with modern ductwork or insulation standards in mind, which is exactly why we run a real Manual J load calculation instead of matching whatever the last unit happened to be — an oversized system in an older, less-sealed house short-cycles and wears out early.
