Signs Your A/C or Heater Needs Service
Comfort is safety — a fogged windshield from a failing heater core can cause accidents. Don't ignore these signs.
-
A/C blows warm or barely cool air even on maximum settings
-
Musty or moldy smell when the A/C runs (dirty or moldy evaporator core)
-
Unusual clicking, banging, or squealing from the A/C compressor
-
A/C only works sometimes — intermittent cooling
-
Heater blows cold air in winter (thermostat, coolant, or heater core issue)
-
Windshield fogs from inside constantly — sign of a heater core leak
-
"Why won't my car A/C get cold?" — the most common question we hear in summer
The Cost of Ignoring A/C Issues
A small refrigerant leak left unchecked does not just leave you sweating — it burns out your A/C compressor, a $600–$1,200 part. Running a low-charge system forces the compressor to work harder, damages compressor seals, and can destroy the entire HVAC system over time. What starts as a $150 recharge can become a $1,500 compressor replacement if ignored for a full summer.

Frequently Asked Questions
Why is my car's A/C blowing warm air?
Warm air is usually caused by low refrigerant due to a leak, a failed compressor, a clogged condenser, or a faulty expansion valve.
How often should car A/C be serviced?
Most manufacturers recommend an A/C inspection every 2 years. Recharging is only needed when refrigerant is low, not on a fixed schedule.
What refrigerant does my car use?
Vehicles made before 2017 typically use R-134a. Newer vehicles use R-1234yf. We service both types at Ibarra's Auto.
Can you find A/C leaks?
Yes. We use UV dye testing and electronic leak detectors to locate even the smallest refrigerant leaks before recharging the system.
How long does an A/C recharge take?
A standard recharge and leak check takes about 1 hour. If a component like a compressor needs replacement, the job can take half a day or more.
