Priority Dispatch from Rialto
Fully Licensed, Bonded & Insured Inland Empire HVAC Specialists
When your air conditioner quits during a 105° heatwave in Rialto, or your furnace stops on a freezing Inland Empire night, you don't need a plumber who "also does AC." You need a dedicated heating and cooling professional who lives this work every day.
BACS HVAC Services dispatches from 823 W Mariana St in Rialto, covering 92376, 92377, and the surrounding cities of Fontana, San Bernardino, Colton, Rancho Cucamonga, and Bloomington. We're 100% focused on heating and cooling — that means faster diagnostics, deeper expertise on inverter and heat pump systems, and zero high-pressure plumbing upsells.
Most chain HVAC companies dispatch from Anaheim, Loma Linda, or Riverside — they're 30+ minutes away. We're often at your door in 8 to 18 minutes for Rialto calls. That speed difference matters when your house is 95° inside.
Every service below is performed by NATE-certified BACS technicians dispatched directly from our Rialto shop. Fixed-rate quotes, written before work begins.

Usually a frozen coil from a clogged filter, low refrigerant, or a tripped breaker. Don't keep it running — the compressor will fail. Diagnostic: $89.
90% dirty flame sensor. 15-minute fix at $145 total including the diagnostic. Other 10% is hot-surface igniter ($215) or limit switch.
First cold-night startup — normal dust burning off. Past 30 minutes, electrical smell, or rotten-egg smell — shut it off and call us immediately.
Often a refrigerant leak, dirty coil, or oversized 12 SEER system. We diagnose root cause vs. just selling you a new unit. Fix one or quote the other.
Don't extend ductwork — you'll undersize your central AC. A single-zone Mitsubishi mini-split solves it for $4,200–$5,800 installed.
