Common Calls

The six AC problems we get called for most.

Some are emergencies. Some are warning shots. All are reasons to call before a small repair becomes a compressor replacement.

Not cooling at all

Usually low refrigerant, a stuck compressor, or a frozen evaporator coil. NATE-certified diagnostics find the root cause — not just the symptom.

Won't turn on

A tripped breaker, bad capacitor, failed contactor, or thermostat issue can all prevent your system from starting. Most of these are same-day fixes.

Unusual noises

Grinding, banging, clicking, and rattling all mean different things. We diagnose before quoting — you don’t pay for parts you don’t need.

Water dripping or pooling

Almost always a clogged condensate drain or a frozen coil that thawed. Either way, water in the wrong place is a same-day call.

Short-cycling

Turning on and off every few minutes wears out compressors fast. Short-cycling usually means low refrigerant, an oversized system, or an airflow problem.

Running but not efficient

Sky-high electric bills with mediocre cooling means the system is working harder than it should. Often caused by a dirty coil, low refrigerant, or failing capacitor.

Recognize any of these warning signs? Our technicians can diagnose the problem and recommend the right repair.

Repair or replace? How to think about it.

Honest framing — not a sales pitch for a new system.

  • Under 8 years old — repair almost always makes sense unless it’s the compressor
  • 8–12 years old — weigh repair cost vs. system efficiency and remaining life
  • Over 12 years old — if repair exceeds ⅓ of replacement cost, replacement usually wins
  • Uses R-22 refrigerant — any recharge needed is a strong replacement signal
  • Multiple repairs in one season — the pattern matters more than any single repair
  • We show you the math — payback period, current SEER vs. new, financing options

Don’t Ignore Small AC Problems

Many air conditioning problems start with small warning signs. Weak airflow, warm air coming from the vents, unusual noises, frequent cycling, or rising utility bills often indicate a repair is needed before the problem becomes more serious.

Scheduling an air conditioner repair early can help prevent damage to major components like the compressor, reduce the risk of a complete system breakdown, and keep repair costs lower. If something doesn’t seem right, it’s always better to have one of our technicians inspect the system before a minor issue becomes a major repair.
