What HVAC Services Do You Offer in Walnut Creek?
Walnut Creek functions as the East Bay's downtown — drawing shoppers, diners, and commuters from across Contra Costa to its upscale Broadway Plaza, vibrant restaurant scene, and BART connections that reach San Francisco in 40 minutes. The residential neighborhoods surrounding that commercial core are equally diverse: historic older homes near downtown, hillside estates with top-rated schools, and newer condo developments near the station — each with its own HVAC story. Galaxy Heating & Air Conditioning knows Walnut Creek well across all of it.
We serve Walnut Creek's varied residential landscape: downtown-adjacent historic homes where ductless solutions fit original architecture; Northgate and Walnut Heights hillside properties with custom homes needing multi-zone solutions; Rossmoor retirement community where reliable, quiet operation is particularly important for residents; newer condo developments near the BART corridor requiring compact, efficient systems; and larger estate homes in the hills where Lennox and Carrier premium systems deliver the performance the properties demand.
Walnut Creek's inland Contra Costa location creates warm, dry summers — temperatures hitting 90–95°F regularly — while the city's hillside neighborhoods experience the slight temperature moderation that elevation provides. Variable-speed heat pumps serve this climate well from every angle: cooling capacity for summer afternoons, efficient heating for mild winters, and smart thermostat integration that optimizes performance around PG&E's time-of-use rates. For Walnut Creek's retirement communities, the quiet operation of modern inverter-driven systems is often as important as the temperature performance.
Walnut Creek homeowners and businesses can access the full Bay Area rebate portfolio — We handle all paperwork and provide flexible financing. Expert commercial HVAC available. Free estimates, 24/7 emergency service. Call (925) 578-3379.
Why Trust Galaxy for Walnut Creek HVAC Service?
From downtown condos to ranch-style homes in Saranap, we understand Walnut Creek's unique climate and housing stock.
We also provide HVAC solutions for commercial spaces in Walnut Creek, ensuring businesses have efficient heating and cooling.
Summers push your AC to the limit with temperatures often reaching the 90s, while cool nights make efficient heating a must. Reliable cooling systems are essential for both homes and businesses to maintain comfort and productivity. That's why we recommend variable-speed heat pumps and ductless systems that deliver optimal comfort year-round with quiet operation. Regular maintenance of HVAC systems helps improve their energy efficiency and prolongs their lifespan. Using programmable thermostats and energy-efficient HVAC systems can significantly reduce utility costs.

Recent Walnut Creek Installations
San Miguel Neighborhood
Installed a Mitsubishi ductless mini-split heat pump system (MXZ-SM36 outdoor with wall-mounted indoor units) in a single-family home in the San Miguel neighborhood of Walnut Creek, CA. The new high-efficiency inverter system now heats and cools previously uncomfortable rooms and has reduced the family's PG&E bill by about 40% compared to their old electric heaters.
Northgate Neighborhood
Replaced an older 80% gas furnace and AC with a high-efficiency, variable-speed 18 SEER2 cold-climate heat pump system sized for a 2,000 sq ft home using the home's existing ductwork in Northgate, Walnut Creek. The new system delivers more even temperatures, quieter operation, and qualified the homeowner for over $2,000 in Bay Area heat pump rebates plus
Downtown Neighborhood
Installed a compact side-discharge Carrier heat pump system (Carrier 37MURA Crossover Series, ideal for tight spaces and low-noise applications) for a downtown Walnut Creek condo with limited outdoor space. The slim outdoor unit fits neatly on a small patio, and the whisper-quiet, variable-speed operation keeps both the homeowner and close neighbors comfortable year-round.
Rudgear Neighborhood
Installed a Mitsubishi MXZ multi-zone 3-zone ductless heat pump system at a Walnut Creek home. The compact inverter-driven outdoor unit serves three indoor zones through a clean painted-to-match line-set chase, delivering independent room-by-room temperature control, efficient heating during cool winter mornings, and powerful cooling for Walnut Creek’s hot summer days — all with whisper-quiet operation.
Parkmead Neighborhood
Replaced an aging gas furnace at a Parkmead Walnut Creek home with a new properly-sized unit. The install included a fresh equipment platform, code-compliant gas and venting connections, refreshed sheet-metal plenum and supply transitions, and a clean condensate setup — delivering quieter, more even heat throughout the home.

What Walnut Creek Customers Say
"I called Galaxy Heating & Air Conditioning when my old system finally gave out during a heatwave in Northgate. They were quick to respond and helped me choose a new energy-efficient AC unit. The installation was seamless, and I’ve already noticed a drop in my energy bills! I can finally enjoy a cool home even when the temperature hits the 90s. Truly a lifesaver!"
"Living in Downtown, my heating system decided to fail on one of the coldest nights of the year. I was worried about the cost, but Galaxy was honest and fair. They came out quickly, diagnosed the problem, and had everything fixed in no time. Now my home is warm again, and I couldn't be happier with their service. It’s hard to find such reliability!"
"I had Galaxy Heating & Air Conditioning come for routine maintenance in my Saranap home before summer hit. I wanted to avoid any surprises with my AC. They were thorough and even found a small issue that could’ve turned into a big problem. My unit is running perfectly, and I feel much more prepared for the hot months ahead. Definitely worth the investment!"
