As Contra Costa County's largest city, Concord has something no smaller suburb can match: genuine neighborhood diversity. Post-war ranch homes in Todos Santos and Concord Northside sit a few miles from newer master-planned developments near Lime Ridge Open Space, while the Downtown BART corridor draws urban residents into a completely different housing type. Each of these environments creates different HVAC challenges — Galaxy Heating & Air Conditioning has built the experience to serve all of them well.
We work throughout Concord's neighborhoods daily: Todos Santos and Clayton Valley families in 1960s–1980s ranch homes where aging systems are ready for heat pump conversion; Monument Corridor residents in mixed residential buildings who need quiet, efficient equipment; Lime Ridge homeowners in newer construction looking to upgrade beyond builder-grade performance; and downtown townhome owners where ductless systems serve multi-level spaces without requiring invasive ductwork installation. As a Contra Costa County contractor, Concord is home territory for Galaxy.
Concord's inland location creates hot, dry summers — 90–95°F is standard, and occasional heat waves push higher. This is warm enough to matter, but not so extreme that it requires the absolute highest-tier equipment specified for coastal desert climates. The right prescription is a well-sized variable-speed heat pump from a reliable brand — American Standard, Carrier, Lennox — that handles Concord's summer heat efficiently, runs quietly in residential neighborhoods, and delivers heating performance during mild winters without a separate furnace.
We offer same-day service throughout Concord with 24/7 emergency availability. All estimates are free, all pricing is upfront, and our diagnostic fee applies toward any repair. Concord homeowners can access Bay Area rebate programs and flexible financing that make heat pump upgrades significantly more affordable. Call (925) 578-3379.
Concord's housing ranges from post-war ranch homes in established neighborhoods to newer master-planned communities near Lime Ridge to urban townhomes and condos downtown. Many older Concord homes have aging HVAC systems that struggle with today's hotter summers or use excessive energy. We specialize in cost-effective upgrades that improve comfort and lower utility bills.
We serve Concord's diverse commercial sector, including retail at Sunvalley Mall and Todos Santos Plaza, restaurants, office buildings downtown, light industrial facilities, and multi-family housing. Our commercial team handles rooftop units, package systems, and tenant improvements with reliable service and competitive pricing.
Concord's inland location creates significant summer heat-temperatures of 90-95°F are routine from June through September, with occasional heat waves pushing higher. This makes powerful, efficient air conditioning essential for comfortable living. We recommend variable-speed heat pumps that deliver strong cooling during peak heat while operating efficiently year-round, providing both exceptional comfort and lower energy bills.

Installed an American Standard variable-speed heat pump system (model Platinum 18 with AccuComfort technology) in a 2,200 sq ft Todos Santos home.

Replaced an aging 13 SEER AC with a high-efficiency 17 SEER2 Carrier variable-speed heat pump in a 1,900 sq ft Clayton Valley home.

"Last summer, our AC decided to quit during a heatwave in Downtown Concord. I called Galaxy Heating & Air Conditioning, and they were at my door within hours. The technician quickly diagnosed the issue and had us cooling down in no time. I was impressed with their professionalism and how they explained everything to me. I'll definitely keep their number handy for future needs!"
"We recently moved into an older home in Todos Santos and knew the HVAC system was on its last leg. Galaxy came in for a full inspection and helped us choose a new energy-efficient system. The installation was seamless, and I could see the difference in our energy bills right away. It’s a relief knowing we’re ready for the summer heat now!"
"During this chilly winter in Clayton Valley, our heater broke down right before a big cold snap. I called Galaxy Heating & Air Conditioning, and they fit us into their schedule immediately. The technician was friendly and thorough, ensuring everything was working perfectly before leaving. I can’t express how much I appreciated their quick response—it made a stressful situation so much easier."

The go-to solution when a standard heat pump won't fit. Built for Concord properties with limited outdoor space — side-discharge airflow opens installation locations that top-discharge units can't use.
