“Furnace died during the polar vortex in Naperville. Our maintenance plan with Summit meant we jumped the queue and had a tech at the door in 2 hours. Neighbors waited 3 days with other companies.”
“Old radiator system converted to forced-air in our Evanston Victorian. Summit designed a system that preserved our original woodwork while actually keeping every room warm. Exceptional craftsmanship.”
“New high-efficiency furnace in Schaumburg. The old one was 80% efficient, new one is 98%. Gas bills dropped by a third and the house heats evenly for the first time.”
Our Approach
HVAC Installation in Chicago
Chicago's brutal winters make furnace reliability a matter of safety, not just comfort — windchill temperatures regularly drop below -20°F, and older homes with aging heating systems face the highest risk of mid-winter breakdowns when every HVAC company has a full queue.
New HVAC system installation in Chicago requires solving the most demanding heating challenge of any market Summit Climate Solutions serves. The design heating load for a Naperville, Schaumburg, or Evanston home is calculated against a design outdoor temperature of -10°F or below — a condition the Chicago metro experiences with regularity — and the heating system must reliably maintain comfortable interior temperatures against that design condition with appropriate capacity reserve for the coldest exceptional events. The transition away from traditional single-stage 80% AFUE gas furnaces toward higher-efficiency modulating systems has significant implications for Chicago homeowners. A two-stage or modulating 96–98% AFUE condensing furnace delivers meaningful comfort improvements over a single-stage unit in Chicago's climate. The ability to run at 60–80% capacity during moderate winter days — which constitute the majority of Chicago's heating season — keeps the system running longer, distributing heat more evenly throughout large Naperville and Schaumburg homes, rather than blasting on at full capacity and overshooting setpoint. Variable-speed blower motors in higher-tier systems add further comfort improvement by circulating air continuously at low speed rather than delivering intermittent blasts. The question of heat pumps in Chicago requires honest engineering analysis. Standard air-source heat pumps lose useful heating capacity rapidly below 35°F and are genuinely impractical as primary heating sources in a market with extended sub-zero periods. Cold-climate heat pump technology — units rated to -13°F with coefficient of performance above 1.0 at 5°F outdoor temperature — has improved the math for Chicago installations, but Summit recommends dual-fuel systems (cold-climate heat pump plus high-AFUE gas furnace as backup) rather than heat-pump-only configurations. The gas furnace backup ensures comfort and safety during the extreme polar vortex events that define Chicago winters at their worst. Evanston and older Chicago-area homes with original pre-forced-air heating configurations represent a specialized installation challenge. Converting a steam radiator system to forced-air involves ductwork design in homes that were not built with ductwork in mind — typically requiring careful placement through interior walls, closets, and chases that preserve the architectural character of older structures. Summit's installation teams have extensive experience with these conversions and provide detailed ductwork design proposals before any work begins.
Emergency HVAC installation situations arise when a repair technician diagnoses a failure that makes repair economically irrational or physically impossible — a seized compressor on a 15-year-old system, a cracked heat exchanger that condemns the furnace, or catastrophic refrigerant loss from a corroded coil. In these moments, homeowners face a compressed decision timeline while living without cooling or heating. Summit Climate Solutions maintains relationships with regional equipment distributors to source systems faster than standard lead times. We complete the load calculation, equipment selection, and full installation quote on the same visit as the failure diagnosis — so you can make an informed decision without a separate appointment. Our crews are available 7 days a week for urgent replacement jobs.
Every installation includes a Manual J load calculation and a post-install commissioning report — documented proof that your system is correctly sized, charged, and airflow-balanced for maximum efficiency and comfort.
Problems We Solve
-
A failed compressor on an older system often costs more to replace than the system's remaining value
-
Cracked heat exchangers condemn a furnace — CO risk means the system legally cannot be returned to service
-
R-22 refrigerant systems that have lost charge cannot be legally recharged and must be replaced
-
Standard equipment lead times of 1–3 weeks are not acceptable when a family has no cooling in 100°F heat
-
Oversized replacement equipment chosen without a Manual J calculation will short-cycle and fail prematurely
-
An aging HVAC system over 12 years old consumes 30–50% more electricity than modern high-efficiency units, quietly adding hundreds of dollars to your utility bill every year while delivering inconsistent comfort.
-
Uneven temperatures between rooms — too hot upstairs, too cold downstairs — often indicate an undersized or improperly designed system that no amount of maintenance will permanently resolve.
-
Refrigerant phase-outs mean that systems running R-22 are becoming increasingly expensive to service as refrigerant prices climb; replacing with an R-410A or R-32 system eliminates this ongoing cost exposure.

Frequently Asked Questions
How quickly can Summit install a replacement HVAC system in an emergency?
For standard residential equipment sizes (2–5 ton cooling, 80k–120k BTU heating), we can typically source and install within 2–3 business days of the failure diagnosis through our priority distributor relationships. We schedule the installation appointment on the same visit as the repair diagnosis so there is no delay between the decision to replace and the start of scheduling.
Do you perform a Manual J load calculation for emergency replacements?
Yes, always. Skipping a Manual J calculation and upsizing 'to be safe' is one of the most costly mistakes in HVAC installation — an oversized system short-cycles, fails to dehumidify properly, and wears out faster. We perform a room-by-room load calculation on-site using your home's square footage, insulation values, window area, and orientation before recommending equipment.
What SEER rating should I choose for an emergency replacement?
SEER2 ratings of 15–18 represent the best value for most homeowners replacing a failed system under time pressure. Premium 20+ SEER2 inverter-driven systems deliver outstanding efficiency but cost significantly more upfront — the payback period may be 8–12 years. For emergency replacements, we help you model the energy cost difference so you can make a rational decision without pressure.
Is financing available for emergency HVAC installations?
Yes. We partner with several HVAC financing programs that offer same-day approval for qualified applicants, with 0% promotional periods and extended payment terms for larger jobs. We present financing options at the time of the installation quote — you should never have to choose between safety and financial stability.
What warranty comes with an emergency HVAC installation?
All equipment installations include the manufacturer's warranty (typically 5–10 years on parts depending on the brand and registration), plus our 1-year labor warranty covering the installation work itself. We handle the warranty registration for you during installation. NATE-certified technicians perform all installs to ensure the manufacturer's warranty remains valid.
Do you offer expedited installation when my system fails completely?
Yes. Emergency replacement calls — when your system has failed and your home is uninhabitable — are prioritized. We can often mobilize an installation crew within 24–48 hours including on weekends, and will bring temporary cooling or heating equipment if the wait exceeds one night.
