Why this partnership
Honest Repair-or-Replace Advice
The team that repairs your system and the team that installs new ones are two companies. So you get a repair when a repair is right, and a replacement only when it really makes sense.
Most AC calls in Orange County end with a repair: a capacitor, a contactor, a fan motor, a clogged drain. But a failed compressor on a 15-year-old system, repeated coil leaks in a coastal home, or a cracked heat exchanger is a different story. Then Pioneer Service prepares a replacement proposal.
