Commercial HVAC Equipment We Install & Repair
We install Carrier, Bosch, and Mitsubishi. We repair any brand.
Package & Rooftop Units
Self-contained heating and cooling in a single cabinet — rooftop or ground-mounted. Common in East Bay retail, light industrial, and small office buildings. We install Carrier commercial package units and service all major brands including Lennox, Trane, and York.
Commercial Split Systems & Air Handlers
Separate indoor and outdoor units for multi-zone commercial applications where a package unit is not practical. We install Carrier, Bosch, and Mitsubishi commercial split systems and service all major brands. All commercial equipment inspected and repaired at the $189 diagnostic rate.
Commercial Ductless Systems
Multi-zone ductless mini-split systems for light commercial spaces without ductwork — small offices, tenant-occupied retail, converted residential space, and multi-family ADUs. Independent zone control per unit. We install Carrier, Mitsubishi, and Bosch ductless systems and service all brands.
Signs Your Commercial HVAC System Needs Attention
Catching problems early avoids emergency downtime, tenant complaints, and costly equipment failures.
- Occupant or tenant comfort complaints — inconsistent temperatures across zones, hot or cold spots that don’t resolve with thermostat adjustment
- System running constantly without holding setpoint — often a refrigerant, compressor, or duct issue; check utility bills for a concurrent increase in energy costs
- Rising utility bills without a change in occupancy or use — degraded system efficiency, often caused by coil fouling, refrigerant loss, or worn electrical components
- Unusual noises from package units, air handlers, or ductwork — grinding, rattling, or squealing during operation or startup
- Visible ductwork problems — damaged, separated, or visibly disconnected duct runs; uneven airflow in specific zones
- Maintenance overdue — commercial leases and manufacturer warranties commonly require documented annual maintenance; overdue service creates lease compliance and warranty liability
- System over 15 years old with recurring repairs — rooftop and package units nearing end of useful life are candidates for a replacement assessment before the next failure
- No heat or cooling in a commercial space — call 510-848-5010 for 24/7 emergency commercial service across Berkeley and the East Bay

What Customers Say About Aarvaks
★★★★★
“I had a duct fan fail in a very heat sensitive wine cellar and Aarvaks came same day to diagnose issue. They ordered the part and picked it up the next day and everything was fixed within 48 hours. Personal service. Professional service. They know their stuff. They are prompt and reliable. Trustworthy.”
★★★★★
“Aarvaks was professional, knowledgeable, friendly, and very efficient with both maintenance and install tasks. Will definitely use their services going forward and highly recommend them to others.”
★★★★★
“Very happy with the quality of service over the last decade+. So when it came time to replace our old A/C and gas furnace with a new and efficient heat pump, we naturally went with Aarvaks and have not been disappointed by their professionalism and quality of work. This is an expensive investment in our home, something I wouldn’t go with just anybody on.”

Recent Installations
A recent light-commercial heating retrofit completed in Berkeley.
Twin Carrier Performance 96 Furnaces + Ecobee Remote Sensors — Berkeley Church
The sanctuary at this Berkeley church hadn’t been reliably warm in years — even when staff turned the heat up manually hours before service. The original furnace had run since the 1940s and was both inefficient and unreliable. We installed twin Carrier Performance 96 two-stage furnaces with MERV 13 filtration and an Ecobee WiFi programmable thermostat with customized remote sensors. The new system holds setpoint reliably, cut utility costs, and lets staff start warming the sanctuary remotely before meetings and services — or run the fan for air-cleaning on smoky days.
Frequently Asked Questions
What types of commercial buildings does Aarvaks service?
Aarvaks services light commercial buildings and small multi-family properties throughout Berkeley and the East Bay — retail, office, restaurant, apartment buildings, and converted residential-to-commercial spaces. We install, repair, and maintain package units, rooftop systems, commercial split systems, and ductless mini-split equipment. For large-scale commercial or industrial projects, call 510-848-5010 to discuss scope.
How much does a commercial HVAC diagnostic cost?
The commercial diagnostic fee is $189, waived if we do the repair. The fee covers a full system inspection and a written repair recommendation with itemized pricing. No work begins until you approve it. Call 510-848-5010 or book online to schedule a commercial diagnostic.
Does Aarvaks service rooftop package units?
Yes. Rooftop and ground-mounted package units are common in East Bay commercial buildings — retail, small office, and restaurant applications in particular. We install and service all major commercial package unit brands. Rooftop access is standard on commercial service calls. The $189 commercial diagnostic fee applies.
Can Aarvaks service all commercial HVAC brands, or only the brands you install?
We service all major commercial HVAC brands for repair and maintenance — Carrier, Bosch, Mitsubishi, Lennox, Trane, Goodman, Rheem, American Standard, Daikin, and others. Aarvaks is a Carrier Authorized Dealer and installs Carrier, Bosch, and Mitsubishi systems. Manufacturer authorization does not restrict which brands we can diagnose and repair. CSLB #1146520.
What is included in a commercial maintenance agreement?
Commercial maintenance agreements include scheduled service visits, priority appointment scheduling, and documented service records. Each visit covers a full system inspection, cleaning of critical components, refrigerant charge verification, electrical component testing, and a written report with all findings. Documented annual maintenance is commonly required by commercial leases and manufacturer warranties. Call 510-848-5010 to discuss a maintenance agreement for your property.
Can Aarvaks coordinate service access directly with tenants in multi-family buildings?
Yes. For multi-family property owners and managers, we can coordinate service scheduling directly with tenants to confirm access without requiring the property owner to be present for every visit. Confirm this coordination arrangement when scheduling.
Do you pull commercial mechanical permits for HVAC work in Berkeley and the East Bay?
Yes. Commercial HVAC installation and replacement requires a mechanical permit in Berkeley and most East Bay jurisdictions — including like-for-like equipment swaps on commercial systems. We handle the permit application process as part of every commercial installation. All work is inspected and meets local code requirements.
How do I decide whether to repair or replace aging commercial HVAC equipment?
If the repair cost approaches or exceeds half the replacement cost of a comparable system, replacement is typically the better investment — especially on equipment over 15 years old. A failed compressor or heat exchanger on an aging unit is often the decision point. We give you both figures — repair cost and replacement cost — so you can decide without pressure. Call 510-848-5010 or book online to schedule a commercial diagnostic.
