AC Installation Services We Provide
We install every major type of residential and light commercial air conditioning system used in Chicago-area homes:
- Central air conditioning installation: Standard split-system AC installations using your existing or upgraded ductwork — the most common installation across Chicago single-family homes
- High-efficiency variable-speed AC installation: Premium 18+ SEER2 systems with variable-speed compressors for the quietest operation, lowest operating cost, and best dehumidification
- Ductless mini split installation: Single-zone and multi-zone systems for homes without ductwork, additions, finished basements, and historic homes where preserving original finishes matters
- High-velocity mini-duct AC installation: Unico and SpacePak systems using 2-inch flexible duct — ideal for Chicago brick bungalows, two-flats, and pre-war homes never designed for central AC
- Heat pump installation for homeowners switching from a furnace + AC combo to a single all-electric system
- Light commercial AC installation for small businesses, condo associations, and multi-unit properties

The Eco Temp HVAC AC Installation Process
Every Chicago AC installation we do follows the same proven 8-step process:
- Free in-home consultation. We visit your home, evaluate your existing system, ductwork, electrical service, and comfort goals.
- Manual J load calculation. We measure and calculate the exact cooling load for your specific home — not a rule-of-thumb estimate based on square footage or your old equipment.
- Written quote with options. We present 2-3 equipment options at different price/efficiency tiers with itemized written pricing. Every line item is transparent — no hidden fees.
- Permit filing. We file all required Cook County or municipal mechanical permits on your behalf and schedule the inspection.
- Equipment ordering. Once you approve the quote, we order equipment from our distributor network — typically 3-7 business days to delivery.
- Installation day. Our crew arrives in marked vehicles with photo ID. Standard installations take 6-12 hours; complex installations may extend into a second day.
- System commissioning. We verify refrigerant charge, airflow, temperature differential, electrical draw, and condensate drainage before considering the job complete.
- Final walkthrough. We show you how the system operates, register the manufacturer warranty on your behalf, and provide all permit/inspection documentation.
How We Size Your New Air Conditioner
Proper sizing is the most important factor in long-term AC performance and the most common reason failed installations underperform. Oversized systems short-cycle, fail to dehumidify, and burn out compressors. Undersized systems run constantly during heat waves and never reach setpoint.
Every Eco Temp HVAC installation begins with a full Manual J load calculation — the ACCA-approved methodology that accounts for your home’s square footage, insulation R-values, window quality and orientation, air leakage rates, ductwork condition, and Chicago-area climate data. We don’t size based on your old equipment’s tonnage. The right system for your home might be smaller than what you had, or it might be larger — Manual J is the only way to know with confidence.
Use our HVAC system cost calculator for a preliminary estimate before your in-home consultation.

Cook County AC Installation Permits
The City of Chicago and Cook County require mechanical permits for residential AC installations, including like-for-like replacements. Permits protect your homeowner’s insurance coverage, ensure code compliance, and are on record when you sell the property. Eco Temp HVAC handles the entire permit process — filing the application, paying the fees (included in your installation cost), scheduling the inspection, and coordinating with the inspector for sign-off. Most Cook County permits clear in 5-10 business days. Suburban municipalities including DuPage, Will, Kane, Lake, McHenry, and DeKalb Counties have their own permit processes, which we also handle.
Brands We Install Across Chicago
We install every major air conditioner brand. Rather than locking you into a single manufacturer line, we recommend the brand and model that best fits your home, budget, and performance goals — Trane, Carrier, Bryant, Lennox, American Standard, Mitsubishi Electric, Daikin, Amana, Rheem, Goodman, Ruud, Payne, and York. For a full breakdown of recommended equipment tiers and brand comparisons, see our New Air Conditioners page.

Need AC Repair Instead?
If your existing system isn’t cooling properly, you’re hearing unusual noises, or you’ve lost cooling on a hot day, you don’t need a new installation — you need a diagnostic. Visit our AC Repair page for same-day service and common troubleshooting guidance. We’ll always recommend repair first when repair makes sense, and only present replacement when it’s the more cost-effective long-term decision. Read our customer reviews to see if we are the right air conditioning company for you!
