Fremont's housing ranges from well-established single-family neighborhoods in Mission San Jose and Irvington to rapidly growing tech-worker communities in Warm Springs to charming historic homes in Niles. Many newer Fremont homes were built with minimal HVAC systems that struggle during the hottest summer days, making system upgrades common.
We serve Fremont's thriving tech and commercial sector, including office parks in Warm Springs, retail centers, restaurants along Fremont Boulevard, and light industrial facilities. Our commercial team handles everything from precision server room cooling to large rooftop units with 24/7 emergency support.
Fremont's inland location creates significant summer heat-regularly reaching 90-95°F from June through September - making powerful, efficient air conditioning essential. We recommend variable-speed heat pumps that deliver strong cooling during peak heat while operating efficiently during mild weather. Heat pumps also provide all the heating you need during Fremont's mild winters, eliminating the need for a separate furnace.

Installed a Lennox variable-speed heat pump system (model EL18XCV with variable-speed air handler) in a 2,400 sq ft two-story home in Mission San Jose, Fremont. The new 19 SEER2 system replaced a 20-year-old AC and furnace, providing significantly quieter operation, more consistent temperatures, and reducing cooling costs by approximately 42%. The homeowner qualified for $2,300 in combined Bay Area rebates and federal tax credits.
Replaced an undersized 14 SEER AC system with a properly-sized 17 SEER2 American Standard variable-speed heat pump in a newer 1,850 sq ft Warm Springs home. The previous system struggled during Fremont's 95°F summer days. The new heat pump keeps the home consistently cool even during heat waves while using less energy, and the homeowner reports 30% lower summer electric bills.
Installed a Mitsubishi ductless mini-split system (model MSZ-GL series with 2 zones) for a historic 1,200 sq ft home in Niles, Fremont. The 1920s home had no existing ductwork and limited attic space. The new ductless system provides efficient heating and cooling without compromising the home's character, with independent control for the main living area and bedrooms.
