AC Recharge / Refrigerant Refill

Frequency: As needed, typically every 2–5 years or if your system isn’t cooling
Why It Matters: Recharging your AC system with refrigerant ensures cold air and optimal AC performance during the summer. We’ll also check for leaks or low pressure.

Compressor Repair or Replacement

Frequency: When the compressor fails or seizes
Why It Matters: The compressor is the heart of your AC system. If it’s not functioning, your AC won’t blow cold air. We test, repair, or replace compressors as needed.

Blower Motor Repair or Replacement

Frequency: As needed if airflow is weak or non-existent
Why It Matters: The blower motor pushes hot or cold air through your vents. A faulty blower means no cabin airflow regardless of system temperature.

Heater Core Inspection & Repair

Frequency: As needed if the cabin won’t warm up or if you smell coolant inside the vehicle
Why It Matters: The heater core provides warm air from the engine coolant. Leaks or blockages can cause poor heating and windshield fogging.

Cabin Air Filter Replacement

Frequency: Every 12,000 to 15,000 miles or annually
Why It Matters: A clean cabin filter improves airflow, keeps allergens and dust out, and improves AC/heating efficiency.

AC System Leak Detection

Frequency: When refrigerant levels drop or AC stops cooling
Why It Matters: We use dye testing and pressure checks to find hidden leaks and prevent refrigerant loss.

Signs Your AC or Heating System Needs Service

Don’t wait for complete failure—watch for these warning signs:

No Cold or Hot Air: AC not blowing cold or heat not warming up properly.
Weak Airflow: Air barely coming out of vents can indicate blower or duct issues.
Strange Smells: Musty or sweet smells can mean mold buildup or coolant leaks.
Odd Noises: Clicking, whining, or banging when the HVAC system is on.
Inconsistent Temperatures: Airflow that changes from hot to cold suddenly.
