What HVAC Services Do You Offer in Livermore?
Livermore summers are no joke. The Tri-Valley's gateway to wine country also happens to be one of the Bay Area's heat capitals — temperatures routinely exceeding 95–100°F from June through September, with occasional heat waves that push well past that. For the wineries and vineyard estates of South Livermore, precise climate control is a business requirement. For the growing neighborhoods of North Livermore, it's the difference between a comfortable summer and a miserable one. Galaxy Heating & Air Conditioning has specialized in Livermore's extreme climate for years.
We serve Livermore's full range of properties: vineyard estates in South Livermore where wine storage zones need precise temperature control alongside whole-home comfort; established neighborhoods in Springtown and Junction West where older undersized systems get replaced with properly calculated alternatives; growing communities in North Livermore where builder-grade equipment needs upgrading; and historic downtown homes where ductless retrofits serve Victorian properties that never had central systems. Our technicians perform Manual J load calculations for every installation — in Livermore's climate, correct sizing isn't optional.
The specific failure mode we see most often in Livermore: homeowners with systems that were sized years ago when summers weren't quite this hot, running constantly during heat waves without reaching the set temperature. These systems aren't undersized because someone cut corners — the climate has genuinely shifted. Today's answer is a variable-speed heat pump with a 18+ SEER2 rating, sized for current conditions, that delivers powerful cooling at 100°F+ while running efficiently during the mild spring and fall weather that bookends Livermore's calendar.
Livermore homeowners qualify for some of the most generous rebate programs in California — 000, and 500–$12,500. Emergency service is available 24/7, especially important during Livermore's peak heat periods. Call (925) 578-3379.
Why Trust Galaxy for Livermore HVAC Service?
Livermore's unique blend of established neighborhoods, wine country estates, and newer developments creates diverse HVAC needs. Many homes have undersized AC systems that were adequate years ago but struggle with today's increasingly hot summers. We specialize in right-sized system upgrades that deliver reliable comfort during extreme heat.
We serve Livermore's wine industry, restaurants, retail spaces on First Street, office buildings, and light industrial facilities. Our commercial team understands critical applications like wine storage climate control, tasting room comfort, and server room precision cooling with 24/7 emergency support.
Livermore experiences some of the Bay Area's most extreme summer heat-temperatures of 95-105°F are common from June through September, with occasional heat waves pushing even higher. This makes air conditioning essential, not optional. We recommend high-efficiency variable-speed heat pumps rated for extreme heat performance. These systems deliver powerful cooling during peak heat while using minimal energy during milder weather, providing year - round comfort with lower utility bills.

Recent Livermore Installations
South Livermore Neighborhood
Installed a Carrier variable-speed heat pump system (model Infinity 18VS with Infinity control) in a 2,600 sq ft South Livermore home with vineyard views. The new 18 SEER2 system replaced an aging 13 SEER AC that struggled during 100°F heat waves. The variable-speed compressor delivers powerful cooling during extreme heat while operating quietly and efficiently during milder weather..
North Livermore Neighborhood
Replaced an undersized 14 SEER AC and 80% furnace with a properly-sized 17 SEER2 Lennox variable-speed heat pump in a 2,100 sq ft North Livermore home. The previous system couldn't keep up during Livermore's hottest days. The new heat pump maintains consistent 72°F comfort even when outdoor temperatures exceed 100°F, and the homeowner reports 38% lower summer cooling costs.
Downtown Livermore Neighborhood
Installed a Mitsubishi ductless multi-zone system (model MXZ-4C36 with 4 zones) for a renovated downtown Livermore home and attached wine tasting room. The system provides precise temperature control for the living quarters while maintaining optimal wine storage conditions year-round. The inverter-driven compressor handles Livermore's extreme temperature swings efficiently while operating whisper-quiet.
Springtown Neighborhood
Installed a new American Standard gas furnace and matching air conditioner at a Springtown Livermore home on Felicia Avenue. The properly-sized system replaced an aging unit with a clean closet install, code-compliant gas and electrical connections, and a tidy new condenser pad alongside the home — giving the homeowner reliable heating for cold Livermore winter mornings and powerful cooling for triple-digit summer afternoons.

What Livermore Customers Say
"When our AC unit broke down during that heatwave in South Livermore, I was in panic mode. I called Galaxy Heating & Air Conditioning, and they had a technician at my door within hours. He quickly diagnosed the issue and had it fixed before I could even finish my iced tea! I was so relieved to have a cool home again. Definitely a lifesaver!"
"Living in North Livermore, our heating system was really struggling this winter. I called Galaxy for maintenance, thinking it might be a lost cause. Their team was punctual and thorough, explaining everything they did. They even suggested ways to improve energy efficiency! Our bills are down, and the house is toasty warm now. I’m so glad I found them!"
"I recently moved into an older home in Downtown Livermore and knew the HVAC system needed an upgrade. I contacted Galaxy Heating & Air Conditioning for a new installation, and they walked me through all my options. The crew was friendly and professional, and they worked quickly. Now, I’m ready for summer without worrying about skyrocketing energy bills. What a relief!"
