How quickly can you come for AC repair in New Lenox?

We offer same-day AC repair in New Lenox in most cases. Call us before noon and we can typically schedule an afternoon appointment. For emergencies, we have 24/7 service available — we answer every call, day or night.

Should I repair or replace my AC unit?

A good rule of thumb: if the repair cost is more than 50% of the cost of a new unit, or if your system is over 12–15 years old, replacement is usually the smarter investment. We'll give you an honest assessment and never push you toward a replacement you don't need.

Why is my AC running but not cooling?

The most common causes are a dirty air filter, low refrigerant, a failing capacitor, a frozen evaporator coil, or a faulty compressor. Our technicians diagnose the exact issue on the first visit so you're not paying for guesswork.
