When your air conditioner finally quits — or the repair bills start outpacing the value of the unit — you need a straight answer and a system that will actually cool your home. Ultimate HVAC Inc. handles AC installation and replacement across Skokie, IL, with same-day service, 24/7 availability, and transparent pricing from the first phone call. If you're comparing installers and want the job done right the first time, we're built for serious homeowners who want serious answers.
What AC installation and replacement involves
Installing or replacing a central air conditioner is more than swapping a box on a concrete pad. It starts with sizing — calculating the cooling load for your Skokie home based on square footage, insulation, window exposure, and existing ductwork. Undersized systems run constantly and never dehumidify; oversized units short-cycle, wear out fast, and leave hot spots.
Once the system is spec'd, the old condenser, evaporator coil, and line set are removed. We inspect the existing ductwork for leaks, undersized returns, or crushed sections that would strangle the new unit. The new condenser is set on a level pad, the indoor coil is matched and sealed to the plenum, refrigerant lines are brazed and pressure-tested, and the system is pulled into a deep vacuum to remove moisture before charging with refrigerant to the manufacturer's spec.
We wire the thermostat, verify airflow at the registers, check superheat and subcooling, and walk you through the controls before we leave. Every step matters — skip one and the system that should last 15 years starts failing in year six.

What AC installation typically costs
An honest answer: it depends. A straightforward replacement where the ductwork, electrical, and line set are all in good shape is at the low end. Costs climb when the system size needs to change, ductwork needs modification, a new pad or disconnect is required, or you're moving from a builder-grade unit to a higher-efficiency variable-speed system. Refrigerant type, SEER rating, and indoor coil matching all factor in.
What's typically included in our quotes: the condenser, matched evaporator coil, new line set or flush of the existing one, refrigerant charge, thermostat if needed, permits, and haul-away of the old equipment. What can add cost: duct repairs, electrical upgrades, or zoning changes. We don't publish a flat price online because a real number requires seeing the home.

FAQ
How long does an AC installation take?
A standard replacement in a Skokie single-family home is typically a one-day job. Larger systems, duct modifications, or full changeouts including the furnace can push into a second day.
Should I replace my furnace at the same time?
If your furnace is 15+ years old and shares the blower with your AC, replacing both together usually makes sense — the coil sits on top of the furnace, and matched equipment runs more efficiently. We handle AC and furnace installation together often.
Do I need new ductwork with a new AC?
Not always. We inspect your existing ductwork during the assessment. If it's leaking, undersized, or crushed, we'll tell you and quote the repair separately so you can decide.
Can you install an AC in an older Skokie home without existing ducts?
Yes. Ductless mini-split systems are a common solution for older homes, additions, or finished attics where running ductwork isn't practical.
What's the $140 seasonal offer?
It's our current seasonal promotion tied to keeping your system running efficiently. Ask about it when you call and we'll explain exactly what's included.
Do you offer emergency AC replacement?
Yes — we're open 24/7, including emergencies. If a failed system can't wait, call us and we'll get moving.
