Top 7 Signs Your AC Needs Repair in Fresno—Before the Valley Heat Strikes
Every Central Valley resident knows how brutal a Fresno summer can be—triple-digit highs are common from June through September, and 2024 even saw a record 112 °F day at Fresno Yosemite International Airport. Waiting until the first major heatwave to fix a struggling air-conditioner can leave you sweating while you hunt for an emergency technician.
Below are the seven most common warning signs our certified, bilingual A & G Heating & Air technicians see when an AC unit is on the brink. If you notice any of these, schedule service before the mercury climbs.
1. Warm Air Blowing from Vents
If the thermostat is on “cool” but room air feels lukewarm, you could have a refrigerant leak, compressor trouble, or a failed capacitor. A quick diagnostic can prevent a full system failure—and higher repair costs—later.
2. Weak or Inconsistent Airflow
Poor airflow often points to a clogged filter, failing blower motor, or duct obstruction. Beyond comfort issues, restricted airflow forces your AC to work harder, driving up energy bills across Fresno’s long cooling season.
3. Rapid On-Off Cycling (Short-Cycling)
An AC that starts and stops every few minutes wastes power and wears out components. Causes include incorrect system sizing, thermostat errors, and iced-over evaporator coils—issues our techs resolve daily in Clovis, Madera, and Visalia.
4. Unusual Noises—Grinding, Screeching, or Banging
No HVAC system is silent, but new metallic or banging sounds signal loose belts, failing bearings, or a damaged fan blade. Shut the unit off and call for service to avoid catastrophic compressor damage.
5. Musty or Burning Odors
A musty smell suggests biological growth on coils or inside ducts, common in our dusty agricultural region. A burning odor could indicate electrical shorts. Either way, turn the system off and book an inspection.
6. Unexplained Spikes in Energy Bills
Fresno County’s time-of-use utility rates already climb in peak hours; an inefficient AC adds insult to injury. If your PG&E bill suddenly jumps but usage habits haven’t changed, the unit may be low on refrigerant or have airflow issues.
7. Moisture or Puddles Around the Condenser
Excess condensation, clogged drain lines, or refrigerant leaks can create water damage or mold. A & G technicians carry the tools to unclog drains, patch leaks, and recharge refrigerant to EPA standards in a single visit.
