Air Conditioning Contractor Chicago
Looking for an Air Conditioning Contractor in Chicago who won't oversell or cut corners? Our installations last longer because the details matter—from load calculations to duct design to refrigerant charge.
Hot, humid Chicago summers demand more than a box with coils. Your AC needs proper sizing for your specific home, ductwork that delivers the right airflow, and installation precision that determines whether you get 8 years or 18 years of service.
High Efficiency Systems
Up to 20 SEER AC systems that cut your summer electric bills while keeping you comfortable during Chicago's hottest days.
Ductless Solutions
No ducts in your vintage Chicago home? Mitsubishi and Daikin ductless mini-splits cool without tearing up your walls.
Perfect Sizing
Manual J load calculations mean your AC is sized exactly right—not guessed based on square footage rules that fail in Chicago's mixed housing stock.
Bernie's Heating & A/C has installed air conditioning in every type of Chicago home since 2008. Century-old bungalows with no ductwork. Three-flats with separate meters. High-rise condos with strict building codes. Two-story brick homes where the second floor bakes. We've done them all.
Chicago summers hit 90°F with 80% humidity regularly. Your AC doesn't just need to cool—it needs to remove moisture, run efficiently during long duty cycles, and survive the stress of keeping up with Lake Michigan's humidity swings. That takes proper installation, not just hauling in equipment.
AC Installation
AC installation means sizing your system correctly for Chicago's climate, matching equipment to your home's duct capacity, and verifying refrigerant charge with precision. Improper refrigerant charge alone cuts efficiency by 20%. Undersized ducts choke airflow and kill compressors early.
We start with Manual J load calculations—not square footage guesses. Your brick bungalow in Belmont Cragin has different cooling needs than a vinyl-sided ranch in Portage Park, even at the same square footage. Window count, insulation, orientation, and Chicago's specific climate data all factor in.
Most Chicago AC replacements take one day. New installations with ductwork run 2-3 days depending on your home's layout. We clean up completely and walk you through operation before we leave.

AC replacement timing matters in Chicago. Wait until July when it's 95°F outside, and you'll pay emergency pricing plus wait days for installation during peak season. Plan ahead in spring, and you have better equipment selection and scheduling flexibility.
Your old AC might be 10 SEER. New minimum efficiency is 14 SEER in Illinois as of 2023. Jump to 16-18 SEER and your summer electric bills drop noticeably. Chicago summers run hot enough that the electricity savings pay back faster than in cooler climates.
AC replacement includes matching your new outdoor condenser to your indoor evaporator coil, verifying ductwork can handle the new system's airflow requirements, and updating your thermostat if needed. Mismatched components waste the efficiency you paid for.

Central AC installation works best when you already have ductwork from your furnace. The ducts deliver cooled air to every room through the same registers that handle heat in winter. Your existing blower in the furnace pushes the air—the outdoor condenser just provides the cooling.
Chicago bungalows often have heating ducts but those ducts might be undersized for AC. Heating needs lower airflow (about 300 CFM per ton) while AC needs higher airflow (400 CFM per ton) to remove humidity properly. If your ducts are marginal, your new AC won't perform well even if it's top quality.
Central AC installation in Logan Square, Avondale, or Irving Park neighborhoods often involves working with older homes where the basement or attic access is tight. We've done hundreds of these installs. Your home isn't special in a bad way—it's just Chicago normal.

Complete AC system design means engineering the whole cooling solution—not just picking a condenser from a price list. Your equipment, ducts, refrigerant lines, controls, and airflow all work together. Optimize one piece while ignoring the others and you waste money.
Many Chicago homes have ducts that were added later or designed only for heating. Proper duct design targets 400 CFM per ton with static pressure under 0.5 inches W.C. Poor duct design can kill 20-30% of your system efficiency even with premium equipment. Airflow matters as much as SEER rating.
Complete AC system installations typically include Manual J load calculations, duct evaluation and redesign if needed, equipment selection matched to your specific home, and system commissioning with verified airflow and refrigerant charge. It costs more upfront but runs better and lasts longer.

Ductless mini-split AC solves the cooling problem for Chicago homes with no ducts or inadequate ductwork. Each indoor unit mounts on the wall and connects to an outdoor condenser via thin refrigerant lines. No tearing up walls, no losing closet space to ductwork.
Vintage Chicago homes in Albany Park, North Center, or Lincoln Square were built for cross-ventilation. Adding central AC means extensive ductwork modifications. Ductless mini-splits cool those homes without the construction mess. Each room gets its own thermostat and you stop fighting over the temperature.
Mitsubishi and Daikin dominate the ductless market for good reason—their systems run quietly, efficiently, and reliably. We install both brands depending on your specific needs and budget. Installation typically takes 1-2 days depending on how many indoor units you need.

Ductless mini-splits handle both cooling and heating with heat pump technology. Your system runs in reverse during winter to extract heat from outside air and move it indoors. In Chicago's climate, they work well down to about 5°F before efficiency drops and your backup heat kicks in.
Multi-zone ductless systems let you cool different areas independently. Cool the bedrooms at night but not the empty living room. Run AC upstairs where heat rises but not in the basement that stays naturally cool. Each indoor unit operates on its own schedule.
Ductless mini-splits achieve SEER ratings above 20 because they avoid duct losses entirely. Chicago's typical duct systems lose 20-30% of conditioned air to leaks and poor insulation. Ductless systems deliver cooling directly to each room with minimal losses.
