Air Conditioning Service Long Island – Trusted Local Experts from Bellmore

Get an Honest AC Quote

Long Island summers are hot, humid, and relentless. When your AC isn’t working, it’s not just about comfort; it’s about getting through August without losing your mind. AJ Services has been keeping Nassau County and Suffolk families cool for over 20 years. We handle everything from emergency repairs to brand new installations, and we show up 24/7.

Our AC Services

  • Central AC Installation — Adding central air to a home for the first time transforms daily life and adds real home value.
  • Central AC Replacement — When your system is failing or aging, we replace it fast and handle all the permits.
  • AC Repair — Same-day and emergency repair for cooling failures, leaks, strange noises, and refrigerant issues.
  • AC Tune-Up — Annual maintenance keeps your system running efficiently and catches small problems before they become big ones.
  • AC Coil Cleaning and System Cleaning — Dirty coils and ductwork reduce cooling and waste energy; we clean them thoroughly.
  • Mini Split Installation — Perfect for homes without ductwork or for adding cooling to specific rooms.
  • Mini Split Repair — High-velocity and ductless splits need specialized service; we do it right.
  • Emergency AC Service — AC down on a Saturday night in July? We’re here. Call (516) 807-8700 anytime.

Signs Your AC System Needs Attention

  • AC isn’t cooling the house like it used to — weak airflow or warm air coming from vents.
  • System is 12 to 15 years old — replacement is often cheaper than continued repairs.
  • Frequent repairs — you’ve had the HVAC company out twice or more in the past two years.
  • High energy bills — your summer electric bill jumped, and your cooling hasn’t changed.
  • Strange noises — rattling, grinding, or hissing from the outdoor unit or indoor handler.
  • Humidity isn’t being removed — home feels clammy even though the thermostat says it’s cool.
  • Refrigerant leaks — repeat leaks mean the system is breaking down internally.
  • Window AC units everywhere — central air is more efficient and less of a hassle.

Why Long Island Homeowners Trust AJ Services

We’re a family-owned company that’s been here for over 20 years. We know Nassau County homes—the 1950s capes with no ductwork, the ranches that need mini splits, the older AC systems that cost a fortune to cool. We’re licensed and insured. We handle our own permits for Nassau County and eastern Suffolk so you don’t have to jump through hoops. We show up on time, do the job right, and clean up after ourselves.

Every AC job includes a proper load calculation so your system is sized correctly—not too big (which leaves you humid) and not too small (which can’t handle peak summer days). We handle emergency calls 24/7 because summer AC breakdowns don’t wait until Monday. And our team is trained on central air, mini splits, high-velocity systems, ductwork design, and everything in between.
