Why is my AC running but not cooling the house?

An AC that runs but doesn't cool is usually caused by low refrigerant (a leak), a dirty condenser coil, a failing compressor, or a frozen evaporator coil. Each has a different fix — a technician can diagnose the exact cause with pressure testing and inspection.

How much does AC repair cost in Barrington, IL?

AC repair in the Barrington area typically costs $150–$700. Common repairs: capacitor replacement $150–$250, refrigerant recharge $250–$450, contactor replacement $150–$250, compressor replacement $1,200–$2,000. We provide upfront pricing before any work begins.

Why is ice forming on my air conditioner?

Ice on an AC unit is almost always caused by restricted airflow (dirty filter or blocked vents) or low refrigerant. Turn the system off and let it thaw, then check your filter. If the problem returns, call a technician — running a frozen AC can damage the compressor.

How often should I replace my AC filter?

Standard 1-inch filters should be replaced every 1–3 months. Thicker media filters (4–5 inch) typically last 6–12 months. A dirty filter is the #1 cause of AC problems — it restricts airflow, causes freezing, and makes the system work harder.

Should I repair or replace my AC unit?

If your AC is over 12–15 years old and needs a major repair (compressor, refrigerant leak), replacement often makes more financial sense. Newer systems are significantly more efficient and may qualify for federal tax credits and utility rebates. We'll give you an honest comparison.
