What Chicago Homeowners Should Know About AC Repair

Most Common AC Problems

Frequent AC failures in Chicago include: low refrigerant charge (leak in the system — not normal consumption), failed capacitor (compressor or fan won't start), dirty evaporator or condenser coil (reduced airflow and efficiency), failed contactor (compressor won't energize), frozen evaporator coil (restricted airflow or low refrigerant), and thermostat or control board issues.

When to Repair vs. Replace

If your AC is over 12–15 years old, uses R-22 refrigerant (no longer manufactured), or requires a compressor replacement, replacement is usually the better investment. A new 16+ SEER2 system will pay back the cost difference in energy savings within 3–5 years. D's Air gives you an honest assessment — we won't push replacement when repair makes sense.

Refrigerant and Environmental Regulations

R-22 refrigerant (used in systems manufactured before 2010) is no longer produced and is extremely expensive when available. R-410A systems are being phased out in favor of R-454B and R-32. If your system uses R-22 and needs a refrigerant recharge, replacement is almost always the more economical choice.

Maintenance That Prevents Repairs

Annual AC tune-ups prevent most common failures. Key maintenance items: clean the condenser coil, check refrigerant charge, test capacitors and contactors, clean the evaporator coil and condensate drain, and verify airflow. A well-maintained AC lasts 15–20 years.
