Antioch's mix of established neighborhoods and newer developments creates diverse HVAC needs. Many homes have undersized or aging AC systems that simply cannot keep up with Antioch's brutal summer heat-regularly reaching 100-105°F. We specialize in properly-sized system upgrades rated for extreme heat performance that deliver reliable comfort when you need it most.
We serve Antioch's commercial sector, including retail centers, restaurants, office buildings, medical facilities, and industrial warehouses. Our commercial team handles rooftop units, package systems, and specialty applications with fast response times and competitive pricing. We understand that AC failures during Antioch summers impact business operations.
Antioch's inland East County location creates some of the hottest temperatures in the entire Bay Area-summer readings of 95-105°F are routine from June through September, with heat waves pushing even higher. This extreme heat makes powerful, reliable air conditioning absolutely essential for livable conditions. We recommend high-efficiency heat pumps specifically rated for extreme heat performance. These systems deliver strong cooling during peak heat while operating efficiently year-round, providing both comfort and manageable energy bills despite the intense climate.

Installed an American Standard variable-speed heat pump system (model Platinum 17 with variable-speed air handler) in a 2,100 sq ft Deer Valley home. The new 17 SEER2 system replaced a struggling 12 SEER AC that couldn't keep up during Antioch's 100°F+ heat waves. The new heat pump maintains consistent comfort even during extreme heat, operates significantly quieter, and reduced cooling costs by approximately 40%. The homeowner qualified for $2,000 in combined rebates.
Replaced an undersized 14 SEER AC with a properly-sized 16 SEER2 Carrier variable-speed heat pump in a 1,900 sq ft Lone Tree home. The old system ran constantly during summer, driving up electric bills and still not achieving comfortable temperatures. The new heat pump delivers reliable cooling even during 105°F days while reducing energy costs by 35%.
Installed a Mitsubishi ductless multi-zone system (model MXZ-3C30 with 3 zones) in a renovated waterfront Rivertown home with limited attic space for ductwork.
