Air Conditioning Service for Hot, Humid Chicagoland Summers
Northern Illinois summers bring stretches of 90-degree days and heavy humidity, which is hard on air conditioners and the people living with them. Pure Comfort Heating and Cooling repairs, replaces and maintains central air systems across Streamwood, Bartlett, Hoffman Estates, Schaumburg and the rest of the Northwest Suburbs. We check refrigerant, airflow and electrical components before deciding what your system needs.
AC repair
Most air conditioner repairs cost between $150 and $700. Our trucks are stocked with capacitors, contactors, fan motors and other common parts, so many repairs are completed the same day. Same-day emergency service is available, and after-hours diagnostics are $99.
AC replacement
A new air conditioner typically costs $5,000 to $9,000 installed, and a complete furnace and AC replacement typically runs $8,000 to $19,000. Most homeowners choose systems in the 14 to 18 SEER2 range, and Lennox models go as high as 26 SEER2. Every replacement includes a load calculation, so the system is sized for your home instead of guessed. New equipment usually arrives within one to two days, an AC-only installation takes four to six hours, and a full system takes seven to ten hours.
Why refrigerant matters
New air conditioners use R-454B, a lower-impact refrigerant. Older systems that still run on R-22 are expensive to recharge because that refrigerant is no longer produced. If your AC is low on R-22, we will explain the cost of a repair compared with a replacement before any work begins.
AC maintenance and humidity control
A spring tune-up is $99 in our main service area. We clean the outdoor coil, check the refrigerant charge, test electrical parts and clear the condensate drain. If your home feels sticky even when it is cool, a two-stage or variable-capacity system, or a whole-home dehumidifier, removes far more moisture than a basic single-stage unit.
Repair or replace?
Replacement usually makes sense when an AC is 12 to 15 years old, uses R-22 or needs a compressor or coil. We give you both prices in writing and let you decide.
What Is Included With a New AC Installation?
- Load calculation so the system matches your home and removes humidity properly.
- Matched indoor coil and a new or flushed refrigerant line set as needed, so the system performs to its rating.
- New pad, disconnect and whip as required, plus a village permit where needed.
- Nitrogen purge, pressure test and deep vacuum before the system is charged with R-454B refrigerant.
- Start-up and testing: refrigerant charge, temperature split and airflow recorded.
- Clean work area, haul-away of the old equipment and a walkthrough of the new thermostat.
- Warranty: Lennox 10-year parts warranty when registered, backed by our own labor warranty.
Most AC-only installations take four to six hours. Learn more on our AC installation page.
Which Lennox Air Conditioner Is Right for Your Home?
Most homeowners in our area choose systems between 14 and 18 SEER2, and Lennox models reach up to 26 SEER2. Good: single-stage air conditioners for dependable, budget-focused cooling. Better: two-stage models that run longer at low speed and pull more humidity out of the air. Best: variable-capacity systems for the quietest operation, the most even temperatures and the lowest electric bills. Compare models on our Lennox air conditioners page or at ENERGY STAR.

Common Air Conditioning Questions From Local Homeowners
How long does an air conditioner last in Illinois?
Most central air conditioners last 12 to 15 years in the Chicago area with regular maintenance. Units near the end of that range, or older systems that still use R-22 refrigerant, are usually better candidates for replacement than for major repairs.
What SEER2 rating should I choose?
Most homeowners in our area choose 14 to 18 SEER2, which balances price and operating cost. Higher-SEER2 two-stage and variable-capacity systems cost more up front but run quieter, control humidity better and lower summer electric bills.
Can I replace just the outdoor unit?
Usually it is best to replace the outdoor unit and indoor coil together. A mismatched coil can lower efficiency, shorten the compressor’s life and affect the warranty. If your system uses R-22, the coil must be replaced to work with today’s refrigerant.
What is R-454B refrigerant?
R-454B is the refrigerant used in new air conditioners and heat pumps. It has a much lower global warming impact than R-410A, which is being phased out of new equipment. Existing R-410A systems can still be serviced.
Why is my AC running but not cooling?
Common causes are a clogged filter, a dirty outdoor coil, a frozen indoor coil, a failed capacitor or low refrigerant from a leak. Replace the filter and make sure the outdoor unit is running, then call us if the house still is not cooling.
Do I need to cover my AC in the winter?
No. Outdoor units are built to handle snow and rain. A full cover can trap moisture and attract rodents. If anything, a piece of plywood on top to block falling ice is enough.
Not sure which one you need? Describe what the system is doing and we will tell you whether it is a repair, a tune-up or a replacement conversation.
Single-Stage vs Two-Stage vs Variable-Capacity AC Compared
A single-stage AC is the lowest upfront cost, a two-stage AC runs quieter and pulls out more humidity, and a variable-capacity AC gives the most even cooling and lowest bills. We install the full Lennox line and repair all major brands.
| Option | Efficiency | Cooling stages | Outdoor sound | Best for | Example models |
|---|---|---|---|---|---|
| Single-stage | Up to 13.4 to 17 SEER2 | Single-stage | As low as 72 to 73 dB | Budget replacements and rentals | Lennox ML14KC1, EL16KC1 |
| Two-stage | Up to 18 SEER2 | Two-stage | As low as 73 dB | Better humidity control at a value price | Lennox ML17KC2 |
| Variable-capacity | Up to 19.5 to 26 SEER2 | Variable-capacity | As low as 58 to 67 dB | The most even cooling, best humidity control and lowest bills | Lennox EL18KCV, EL22KCV, SL25KCV |
