HVAC Company Serving Vallejo, CA

Master Craftsmanship and Local Accountability Just Minutes Away

If your furnace quit during a January cold snap or your air conditioner failed on a hot afternoon, you need a team that shows up promptly and gets the job done right the first time. Environmental Heating & Air Solutions delivers full-service heating, cooling, and indoor air quality performance across Solano County without the shortcuts or unnecessary upsells. 

Our office is in Benicia, just a quick drive down I-780 from Vallejo, so same-day or next-day appointments in Vallejo are standard. We work at or above manufacturer specifications on every job, whether it is a furnace repair on a cold morning or a full system replacement planned months ahead.

What Bay Breeze and Older Housing Stock Mean for Your System

Vallejo's bay breeze keeps summer highs several degrees below inland Solano County towns, but a system sized for an older, milder pattern often struggles once October's warm afternoons stretch into November. Homes in Vallejo Heights and other grid neighborhoods near downtown still carry original ductwork and electrical panels from the era around the old Mare Island Naval Shipyard, while newer construction in Glen Cove and Hunter Ranch runs equipment built for a different code cycle entirely. 

Our NATE- and BPI-certified technicians run load calculations and blower door testing before recommending a replacement, so the system installed matches the house in front of them, not a generic size chart. 

If the ductwork dates back this far, a repair alone rarely fixes airflow problems in every room.

HVAC Services We Handle for Your Home

Because our team treats your home's HVAC system as a complete, integrated unit, a single appointment resolves airflow, heating, and cooling issues thoroughly. 

Homeowners across Solano County call us for: 

• Heating repair and replacement – Furnace, heat pump, and electric or gas system service, with complete diagnostics before we write any repair estimate. 
• Air conditioning and ductless mini-splits – Central AC repair, replacement, and mini-split installation for additions or homes without existing ductwork. 
• Indoor air quality and energy efficiency – Duct sealing, whole house fans, air scrubbers, and blower door testing tailored to older Vallejo construction. 

Each service connects back to the same precise load calculation and diagnostic approach, helping your heating and cooling equipment operate at peak efficiency year-round. 

The Certifications that Back What Our Technicians Tell You

Environmental Heating & Air Solutions holds Lennox Premier Dealer status—a designation fewer than three percent of HVAC contractors nationwide carry—and earned the Dave Lennox Award in 2022, 2023, and 2024, an honor limited to under one percent of Lennox dealers each year. 

Our technicians hold NATE and BPI certifications, and our Pearl certification documents how system upgrades directly improve a home's energy performance and resale value alongside its comfort. 

Homeowners on our Energy Saving Agreement (ESA) maintenance plan get priority scheduling and a locked-in parts-and-labor warranty on repairs—details worth asking about before an aging system meets a Vallejo summer.
