Why is My AC So Inefficient?

If your AC is running constantly but your house is still warm, or your bills are creeping up, it's likely one of these common (and repairable) issues:

Problem 1: Dirty CoilsYour inside (evaporator) and outside (condenser) coils are where heat is exchanged. In San Mateo, CA, they get caked with dust. A dirty coil is like trying to run with a plastic bag over your head—it chokes the system and wastes energy.
Problem 2: Low Refrigerant (Freon)Refrigerant is the "blood" of your AC. If it's low, it means there is a leak. This makes your AC run for hours, unable to reach the set temperature. We can find the leak, repair it, and recharge the system.
Problem 3: A Failing CapacitorThe capacitor is a small part that "jump-starts" your compressor and fan motor. When it fails, the motors struggle to start, drawing a huge amount of (wasted) electricity. This is a simple, common fix.
