Looking for San Jose's most trusted HVAC contractor? Galaxy Heating & Air Conditioning is your local expert for air conditioning, heating, and heat pump solutions across all San Jose neighborhoods. With proven brands like Carrier, Lennox, Mitsubishi, and American Standard, we deliver reliable comfort to Silicon Valley's largest city. San Jose's warm summers and tech-savvy residents demand efficient, smart HVAC systems.
Galaxy Heating & Air Conditioning proudly serves San Jose homeowners and businesses, from historic neighborhoods like Willow Glen and Rose Garden to tech hubs downtown to sprawling communities in Almaden Valley and Evergreen. 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 San Jose's unique needs: tech-industry professionals who appreciate energy-efficient, smart home-integrated systems; hot summer temperatures requiring powerful cooling; and incredibly diverse housing from 1920s bungalows to modern condos. Our team provides transparent pricing, expert installations, and reliable service. We're available 24/7 for emergencies. Preventive maintenance ensures year - round comfort and maximum efficiency.
To make HVAC system upgrades accessible, we offer flexible financing with convenient monthly payments (on approved credit). Whether you're upgrading to a smart heat pump system, replacing aging equipment, or adding ductless comfort to a converted ADU or home office, we'll help you find a payment plan that works.
San Jose's massive housing diversity - from charming historic neighborhoods like Willow Glen, Rose Garden, and Naglee Park to sprawling newer communities in Almaden Valley, Evergreen, and Silver Creek-creates varied HVAC needs. Many tech-industry homeowners are upgrading to smart, energy-efficient heat pumps with Wi - Fi thermostats and zone control capabilities.
We serve San Jose's vast commercial sector, including downtown office towers, retail centers, restaurants along Santana Row, tech campuses, medical facilities, and industrial warehouses. Our commercial team delivers precision climate control, server room cooling, and rooftop unit service with 24/7 emergency support. We understand the critical nature of climate control in tech environments.
San Jose's South Bay location creates significant summer heat-temperatures routinely reach 85-95°F from June through September, with inland areas like Almaden and Evergreen often hotter than bayside neighborhoods. This makes powerful, efficient air conditioning essential. We recommend modern variable-speed heat pumps that deliver strong cooling during peak heat while operating efficiently year-round. These systems integrate seamlessly with smart home platforms popular among San Jose's tech workforce and eliminate the need for a separate gas furnace.

Installed a Carrier variable-speed heat pump system (model Infinity 19VS with Infinity control and smart home integration) in a 3,000 sq ft Almaden Valley home. The new 19 SEER2 system replaced a 14 SEER AC and old furnace, providing app-based control, whisper-quiet operation, and reducing cooling costs by approximately 44% during San Jose's hot summers.

Replaced a failing 16-year-old AC with a high-efficiency 18 SEER2 Lennox variable-speed heat pump in a classic 1,900 sq ft Willow Glen bungalow.
