Our NATE-certified technicians provide expert service for all heating, cooling, and air quality needs. As a fully licensed HVAC contractor, we meet all local codes and manufacturer standards.
We understand Dublin's needs: families seeking reliable, efficient systems; hot summer temperatures requiring strong AC performance; growing homes with bonus rooms and home offices needing climate control; and quality-conscious homeowners who appreciate energy savings.

Dublin's housing includes well-maintained master-planned communities with newer construction alongside established neighborhoods. Many homeowners are upgrading to efficient heat pumps that provide both heating and cooling with smart thermostat integration. The prevalence of home offices in Dublin makes quiet, reliable climate control especially important for remote workers.
We serve Dublin's commercial sector, including retail at Dublin Crossing and Hacienda Crossings, restaurants, office buildings along Hacienda Drive, medical facilities, and data centers. Our commercial team handles rooftop units, package systems, and precision cooling applications with reliable service and competitive pricing.
Dublin's Tri - Valley location creates significant summer heat-temperatures routinely reach 90-95°F from June through September, with occasional heat waves pushing to 100°F+. This makes powerful, efficient air conditioning essential for comfortable living. We recommend modern variable-speed heat pumps that deliver strong cooling during peak heat while operating efficiently year-round. These systems integrate with smart home platforms and eliminate the need for a separate gas furnace.

Installed a Carrier variable-speed heat pump system (model Infinity 17VS with Infinity control) in a 2,400 sq ft Dublin Ranch home. The new 17 SEER2 system replaced a 13 SEER AC and furnace, providing app-based smart control, quieter operation, superior humidity management, and reducing energy costs by approximately 39%. The homeowner qualified for $2,100 in combined Bay Area rebates and federal tax credits.
Replaced an undersized 14 SEER AC with a properly-sized 16 SEER2 American Standard variable-speed heat pump in a 2,200 sq ft Schaefer Ranch home. The previous system struggled during Dublin's 95°F summer days. The new heat pump maintains consistent comfort even during heat waves, operates significantly quieter, and the homeowner reports 35% lower summer cooling costs.
Installed a Mitsubishi ductless multi-zone system (model MXZ-3C30 with 3 zones) for a converted home office and bonus room in an Emerald Glen home. The existing central system couldn't adequately serve these spaces without expensive ductwork modifications. The new inverter-driven system provides independent temperature control, operates whisper-quiet for video calls, and handles Dublin's heat efficiently.
