Common AC Problems
We Fix in Westchester

From refrigerant leaks to failed compressors, our licensed technicians diagnose and repair the full range of air conditioning problems — on all makes and models, the same day you call.

❄️
AC Not Cooling

Your system runs but the air coming out isn't cold — or isn't cold enough. Common causes include low refrigerant, a failing compressor, dirty condenser coils, or a clogged filter. We diagnose the root cause and fix it, not just the symptom.

💧
Refrigerant Leaks

Low refrigerant is one of the most common reasons an AC loses cooling power. Our EPA-certified technicians locate and repair refrigerant leaks, then properly recharge your system to manufacturer specifications.

🔊
Strange Noises

Banging, clanking, squealing, or grinding sounds all point to specific mechanical problems — loose parts, failing bearings, or compressor issues. We identify and fix the source before it becomes a larger, more expensive repair.

🧊
Frozen Evaporator Coils

Ice buildup on your evaporator coil usually signals airflow restriction or a refrigerant problem. We thaw the system safely, find the cause — dirty filters, blocked vents, or low refrigerant — and prevent it from recurring.

Electrical & Capacitor Failures

Faulty capacitors, tripped breakers, damaged contactors, and wiring issues can all cause an AC to fail to start or shut off unexpectedly. Our technicians carry common electrical components on every service vehicle for quick replacements.

🌡️
Thermostat Problems

A miscalibrated or malfunctioning thermostat can cause your system to short-cycle, run constantly, or not respond at all. We test, recalibrate, or replace your thermostat to restore accurate temperature control.

💨
Poor Airflow

Weak airflow from your vents can result from clogged filters, blocked ductwork, a failing blower motor, or a collapsing flex duct. We trace the airflow path and restore proper delivery throughout your Westchester home.

🔄
Short Cycling

An AC that turns on and off repeatedly never reaches your target temperature and puts excessive wear on components. Short cycling is often caused by an oversized system, refrigerant issues, or a failing compressor — all fixable with proper diagnosis.

💧
Drainage & Water Leaks

If you're seeing water around your indoor unit, a clogged condensate drain line is usually the culprit. Left untreated, it can cause water damage and mold growth. We clear the blockage and inspect the drain pan and line for damage.

Don't Ignore These Warning Signs

Signs Your AC
Needs Repair Now

Catching a problem early almost always means a simpler, less expensive repair. Here are the warning signs Westchester homeowners should never ignore — and when to call us before a small issue becomes a full system failure.

  • !
    AC Is Running But Not Cooling Your system is on but your home isn't getting cooler — or it's cooling unevenly room to room. This is the most common AC complaint in summer and can indicate low refrigerant, a dirty coil, or compressor trouble.
  • !
    Warm Air Coming from Vents If your vents are blowing air that's room temperature or warmer, the cooling process has broken down somewhere in the system — often the refrigerant circuit or the compressor.
  • !
    Unusual Noises During Operation Banging, rattling, squealing, or grinding sounds are your AC's way of telling you something is wrong mechanically. Don't wait — these sounds often precede a complete breakdown.
  • !
    Spiking Energy Bills A sudden increase in your electric bill without a change in usage usually means your AC is working significantly harder than it should — a classic sign of a developing problem.
  • !
    Moisture or Ice Around the Unit Pooling water near your indoor unit or ice on the refrigerant lines are never normal. Both indicate problems that will worsen quickly if left untreated.
  • !
    Musty or Burning Smells Musty odors point to mold in the drain pan or ductwork. Burning smells suggest an electrical issue. Either one warrants an immediate service call.
  • !
    Frequent On/Off Cycling Short cycling puts extra strain on your compressor and dramatically shortens system life. If your AC is running in short bursts rather than sustained cycles, it needs attention.

★★★★★

"Called on a Sunday evening when our AC stopped working mid-heat wave. A technician was here within two hours. Turned out to be a bad capacitor — he had the part on the truck, replaced it on the spot, and the house was cool again by 9pm. Unbeatable service."

Why is my AC running but not cooling my house?
This is the most common AC complaint we hear from Westchester homeowners in summer. The most likely causes are: low or leaking refrigerant (which reduces cooling capacity), dirty evaporator or condenser coils (which block heat transfer), a clogged air filter (which restricts airflow), a failing compressor (which can no longer circulate refrigerant effectively), or a frozen evaporator coil. A technician can pinpoint the exact cause with a diagnostic inspection — call 914-762-9600 for same-day service anywhere in Westchester County.
AC repair costs in Westchester vary widely depending on the problem. A capacitor replacement — one of the most common repairs — typically runs $150–$350. Refrigerant recharge (plus leak repair) can range from $200–$600 depending on the amount needed and the refrigerant type. More involved repairs like a compressor replacement can run $800–$2,500 or more. We provide a full written estimate before any work begins, so you know exactly what you're paying. We never start work without your approval.
Yes. Carey & Walsh provides 24-hour emergency AC repair throughout Westchester, Putnam, and Rockland counties — nights, weekends, and holidays included. Call 914-762-9600 any time for immediate assistance.
A good rule of thumb is the "5,000 rule" — multiply the age of your system by the estimated repair cost. If that number exceeds $5,000, replacement is usually the smarter investment. For example, a 12-year-old system with a $500 repair estimate ($6,000) may be better replaced than repaired. We'll give you an honest assessment based on your system's age, condition, and repair history — no pressure toward either option.
We service all residential and commercial AC brands, including Carrier, Trane, Lennox, Bryant, York, Rheem, Goodman, American Standard, Daikin, LG, and more. As a Mitsubishi Electric Diamond Contractor — the highest dealer designation — we're one of Westchester's most qualified service providers for Mitsubishi ductless mini-split systems specifically.
Yes — a clogged air filter is one of the most common and easily preventable causes of poor AC performance. A dirty filter restricts airflow over the evaporator coil, which can cause the coil to freeze and the system to lose cooling capacity entirely. Check your filter first if your AC isn't cooling well. Filters should generally be replaced every 1–3 months during cooling season. If a new filter doesn't resolve the issue, call us for a diagnostic.
