Request Your System Assessment

Consistent Temperature

No more sweltering upstairs bedrooms or cold drafts on the ground floor.

Whisper-Quiet Sound

Modern compressors and vibration-dampened mounts keep mechanical noise to a minimum.

Balanced Humidity Control

Effective moisture removal eliminates that sticky, heavy feeling inside your living spaces.

Lower Operating Costs

High SEER2 efficiency converts more electrical energy directly into cool comfort with less waste.

System Assessment

Is Your Current AC Keeping Up?

Air conditioners rarely fail without warning. If your current unit is struggling to keep pace, look for these common warning signs that replacement may be the smarter investment.

Speak with a Technician

Frequent & Costly Repairs

When repair bills begin stacking up every season, investing that money into a dependable new system offers significantly better long-term value.

Uneven Cooling & Persistent Hot Spots

Rooms on upper floors or south-facing sides of the home remain uncomfortably warm despite the AC running continuously.

Rising Energy Bills Each Summer

A declining compressor and clogged internal coil force the system to run longer cycles, visibly spiking your monthly electric bill.

Aging Equipment (10–15+ Years)

Most residential systems operate reliably for 10 to 15 years. Older units typically utilize obsolete refrigerants and suffer frequent breakdowns.

Excessive Noise & Humidity Issues

Loud squealing, grinding, or a house that constantly feels humid indicates significant mechanical wear and reduced moisture extraction capacity.

Questions About AC Installation?

Find straightforward answers to common homeowner questions about system sizing, installation timing, and performance.

As a general industry guideline, if your AC system is over 10 to 12 years old and facing a repair estimate that exceeds 30–50% of the cost of a new unit, replacement is often the more cost-effective decision. Modern high-efficiency systems also significantly lower electrical operating costs and eliminate frequent breakdown hassles.
A standard residential AC replacement is typically completed within a single day (usually 4 to 8 hours). Complex installations involving complete ductwork modifications or multi-zone mini-split installations may require additional time, which our technician will outline clearly during the upfront consultation.
System sizing should never be guessed by square footage alone. Our technicians perform a thorough Manual J cooling load calculation taking into account window exposure, ceiling heights, insulation levels, and duct configuration to ensure your equipment is sized precisely for peak efficiency and optimal humidity removal.
Key factors include the system tonnage (capacity), SEER2 energy efficiency rating, equipment brand and tier (e.g. single-stage vs. variable-speed), whether ductwork repairs or electrical upgrades are required, and accessibility of the outdoor condenser and indoor evaporator coil.
Yes. Many Chicago and Skokie-area homes have older duct systems or radiator heat. We inspect your existing ductwork to make necessary airflow adjustments or recommend ductless mini-split solutions for homes where installing extensive new ductwork is not practical.
Our technicians will arrive on schedule with protective drop cloths for your flooring. We safely reclaim old refrigerant, disconnect and remove the existing unit, set and level the new condenser, install the indoor evaporator coil, test the line pressure, verify proper thermostat operation, and clean up the work area completely.
To maintain manufacturer warranties and peak efficiency, we recommend replacing your furnace/air filters every 1 to 3 months and scheduling an annual pre-summer cooling tune-up to inspect electrical connections, verify refrigerant charge, and clean the outdoor coil.
Yes. Ultimate HVAC is fully licensed, bonded, and insured. All our technicians hold EPA Section 608 Universal Certifications, ensuring full compliance with state and municipal building and environmental codes.
