Our NATE-certified technicians specialize in systems that perform reliably during 100°F+ heat waves. As a fully licensed HVAC contractor, we meet all local codes and manufacturer standards.
We understand Livermore's extreme climate challenges: brutal summer heat that tests equipment limits, significant day-to-night temperature swings, and the need for systems that perform reliably year after year. Our team provides honest assessments, properly-sized equipment, and expert installation. We're available 24/7 for emergencies-critical during Livermore heat waves.

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.

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. The homeowner qualified for $2,200 in combined rebates and tax credits.
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 new heat pump maintains consistent 72°F comfort even when outdoor temperatures exceed 100°F, and the homeowner reports 38% lower summer cooling costs.
Installed a Mitsubishi ductless multi-zone system (model MXZ-4C36 with 4 zones) for a renovated downtown Livermore home and attached wine tasting room.
