CJM Plumbing, Heating & AC

AC Repair and Installation in New Windsor, NY

Q: How fast can you get here for same-day AC repair?

When scheduling allows, we offer same-day AC repair for systems that stop cooling suddenly or can’t keep up with the heat. Availability depends on the day and current workload, but we always try to prioritize non-cooling situations. If your AC just failed, call us and we’ll let you know the fastest arrival window.

Q: Do you offer emergency AC repair after hours?

Yes, depending on technician availability, we provide emergency AC repair for urgent situations like total system failure during extreme heat. If your home or business is getting dangerously warm, contact us right away so we can help as quickly as possible.

Q: What are the signs I need air conditioner repair instead of waiting it out?

Warm air from vents, weak airflow, strange noises, musty or burning smells, frozen coils, water leaks, or rooms that never reach the set temperature all indicate a problem you shouldn’t ignore. If you’re noticing any of these, schedule air conditioner repair so the issue doesn’t turn into a bigger and more expensive breakdown.

Q: Is air conditioner installation the right choice if my AC still “kind of” works?

If the unit cools unevenly, costs more to run, or needs frequent service, a new air conditioner installation may save you money long-term. Older systems often waste energy even when they are still turned on. If you want to know whether repair or replacement is smarter, we can evaluate your system and give you a clear answer.

Q: Do you work on both home AC repair and commercial AC repair?

Yes. We handle residential and commercial cooling systems, including rooftop units, split systems, and high-demand commercial setups. If your home or building is too warm, we can diagnose the issue and get it cooling properly again.

Cooling that keeps your home or business comfortable and ready for the hottest days.

Your AC Repair and Installation Questions

Answered Clearly and Without Confusion

How do I know if I need an AC repair or a full AC replacement?

If your AC is older than 12–15 years, breaks down repeatedly, or struggles to cool even after repairs, replacement is usually more cost-effective. If the issue is isolated, like a failed capacitor, clogged coil, or thermostat problem, an AC repair is enough.

If you’re unsure which one you need, we can inspect the system and tell you exactly what makes sense for your home or business.

CJM had to come twice this week. The first time to service our oil burner and the second time, Makaya, came to repair our leaky kitchen sink. Both times the servicemen did a great job - friendly, competent and expedient. I didn't catch the name of the first service person, but Makaya did a great job with our sink. Quick and pleasant --- even whistled while he worked. Literally. LOL. The woman who handles the phone is a great rep, too. Great doing business with this organization.
