Full-Service Heating, Air & Ventilation Care for the East Bay
Cozy Conditions handles heating, air conditioning, and ventilation work for homes and light commercial properties across the East Bay. We repair, install, replace, and maintain HVAC systems — from routine upkeep to full electrification upgrades. One team handles the job from diagnosis through completion.



Homeowners, Property Managers & Businesses
Cozy Conditions works with three types of customers across the East Bay, and each gets the same direct line to our team.
Homeowners
Homeowners across Antioch, Brentwood, Oakley, Pleasant Hill, Concord, Pittsburg, Lafayette, Walnut Creek, Orinda, Martinez, Alamo, Dublin, Livermore, Berkeley, Oakland, San Leandro call Cozy Conditions for everything from a furnace acting up in the middle of winter to a full AC replacement before summer. We handle single repairs and larger system upgrades with the same attention.
Property Managers & Landlords
Rental properties and multi-unit buildings need HVAC issues resolved fast, without disrupting tenants longer than necessary. We coordinate directly with property managers and landlords to diagnose the problem, present options, and complete the repair or replacement on a schedule built around occupied units.
Light Commercial & Business Properties
Retail spaces, offices, and other light commercial properties across our service area rely on Cozy Conditions for heating, cooling, and ventilation work sized to their systems. We handle repair, installation, and maintenance for business owners who need a working system with minimal downtime.
Full-Service Residential & Light Commercial HVAC
Cozy Conditions covers the full range of residential and light commercial HVAC work, from routine repairs to full system installation.
Heating Repair & Installation
Furnace and heating system repair, replacement, and new installation for homes and businesses across the East Bay. From a furnace refusing to start to a full heating system swap, we diagnose the issue and walk through the options before any work begins.
AC repair, replacement, and installation, sized and set up for East Bay summers. We work on central air systems and standalone units, and we size new installations around the specific property rather than a one-size approach.
Ventilation & Indoor Air Quality
Airflow, ductwork, and ventilation work supporting healthier, more even indoor air. Uneven temperatures from room to room often point to a ductwork or airflow issue, and we track down the cause instead of only treating the symptom.
Mini-Split, Heat Pump & Multi-Zone (VRF) Systems
Modern all-electric heat pump technology — ductless mini-splits and multi-zone VRF systems that heat and cool different rooms independently. It's where residential HVAC is headed: quieter, more efficient, and built around electrification instead of gas.
System Replacement & Upgrades
Full HVAC system replacement when an aging unit no longer keeps up with demand. We walk through equipment options, present a straightforward recommendation, and handle removal and installation of the new system.
Maintenance Plans
Scheduled maintenance to keep heating and cooling systems running efficiently year-round. Regular visits catch worn parts, low refrigerant, and other small issues while they are still inexpensive to fix.

Why Homeowners & Businesses Call Us
Cozy Conditions handles routine maintenance, repair, and installation work, so one call covers the full range of HVAC needs. We work directly with homeowners and property managers, and we handle residential and light commercial systems with equal attention to detail. Every job, large or small, gets the same follow-through from start to finish.
A single company handling repair, installation, replacement, and maintenance means fewer companies to call and fewer gaps between diagnosis and fix. Homeowners get a team already familiar with their system after the first visit, and property managers and business owners get one contact who understands both residential and light commercial equipment.
Our focus is repairing and modernizing the equipment you already have — bringing it up to today's standards for efficiency and cleanliness — or, when it's time for something new, helping you move away from gas-fired equipment entirely with modern, all-electric, high-efficiency systems.
Tired of a larger company always trying to sell you more than you need? Cozy Conditions is a small, local team — we look at what your system actually needs and tell you straight, without the upsell.
