AC Services in New Windsor, NY

Q: Why is my AC running but barely cooling anything?

When an AC struggles to cool, it’s usually fighting against something like low refrigerant, dirty coils, or blocked airflow. The system keeps running harder than it should, but the temperature inside barely changes. A setup in that condition won’t recover on its own. Booking an AC repair visit lets us get the system back to producing actual cold air instead of wasting energy.

Q: Why does one part of my house stay hot while the rest cools fine?

Uneven temperatures usually point to an airflow issue. Sometimes the blower isn’t pushing enough air, sometimes ductwork is clogged or leaking, and sometimes the system just isn’t sized correctly for the home. Instead of guessing, it helps to let a tech check the airflow and get every room cooling the way it should.

Q: What causes the AC to shut off out of nowhere?

Sudden shutdowns are a sign that something inside is overheating or a safety control is kicking in. This happens when components wear out, refrigerant levels drop, or the system is straining more than it can handle. Once the unit starts doing this, the problem tends to repeat. An inspection tells you exactly what’s tripping the shutdown so it doesn’t keep happening.

Q: Why is my AC making strange noises?

Rattling, grinding, buzzing, and squealing all mean different problems, but none of them are harmless. Noises start when parts loosen, motors wear down, or components begin to fail. Ignoring the sound almost always leads to bigger repairs. A quick visit lets us catch the issue before it takes the whole system down.

Q: Should I repair my older AC or replace it?

Age, performance, and repair history tell the real story. An older unit that runs nonstop or breaks down each season is usually at the end of its lifespan. A newer unit with a single problem may only need a simple fix. We look at the system’s condition and give you a clear recommendation so you’re not wasting money on the wrong choice.

Q: How often should an AC be maintained?

A yearly tune-up keeps the system clean, efficient, and dependable through the hottest weather. Skipping maintenance makes the unit work harder than it should, drives up energy bills, and shortens its lifespan. A simple maintenance visit keeps the cooling steady and prevents most surprise breakdowns.

When an AC system starts to fail, you feel it instantly. Rooms warm up quickly, airflow gets weaker, and the unit shuts off when the temperatures climb.

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.
