Commercial Refrigeration · Stanislaus County
Refrigeration is not a side job here. It is the job.
Your product is only as good as the box holding it. Restaurants, markets, c-stores and cold storage across the 209. Flat $150 service call credited to the repair, EPA 608 certified techs, documented readings every visit, and down equipment dispatched first.
How We Work
Diagnose. Document. Then quote.
Most refrigeration invoices arrive with a part number and a total. Ours arrive with the readings that justified the part.
Superheat and subcool tell you whether a system is charged correctly or just running. Defrost termination tells you whether the coil is icing because of a timer, a sensor, or a door that stopped sealing eight months ago. Fixing the symptom without those numbers is how the same walk-in fails three times in one season.
That discipline is the reason the $150 diagnostic exists as its own line item. It is not a trip charge dressed up. It is the part of the job that decides whether the repair holds.

Trusted Accounts
Companies that only trust Air Techs
We service every one of their locations across the Central Valley and the Bay Area. When a chain trusts one shop with all of its cold, that is the reference that matters.
For Contractors and Property Managers
Sub us in. We show up, we are licensed, and we do not make you babysit the scope.
General contractors, restaurant build-out crews, property managers and HVAC shops that do not do refrigeration bring us the cold side. Line sets, condensing units, walk-in boxes, rack systems, startup and commissioning.
We hold C-20 / C-38 under CSLB Lic. #10086412, insurance is on file, our techs are EPA 608, and other HVAC shops already sub us in when the refrigeration gets difficult. We have been flown to other states for jobs where the local trade could not close it. Send the plans. You get a number and a date.

FAQ
Common questions
What is the fastest way to get a tech out?
Call (510) 927-6675. Down equipment is dispatched ahead of scheduled maintenance and you get a window on the phone rather than a callback promise.
Do you stock common parts?
Contactors, capacitors, defrost timers and controls, thermostats, door gaskets and the usual failure points ride in the truck. Compressors and specialty parts are sourced same-day where suppliers allow.
Can you document readings for health inspections?
Every visit. Temperature and pressure readings are logged and provided in writing, which is what an inspector actually wants to see when they ask about your cold chain.
Do you handle refrigerant compliance?
Our techs are EPA Section 608 Certified. Recovery, charging and leak repair are handled and logged the way the EPA expects.
Do you take subcontract refrigeration work?
Yes. General contractors, build-out crews, property managers and other HVAC shops bring us the cold side, and other shops call us when the refrigeration gets difficult. C-20 HVAC and C-38 Refrigeration under CSLB Lic. #10086412, insured, EPA 608. Send the scope and you get a number and a date.
What is a Cold Chain Plan?
Our preventive maintenance agreement for commercial refrigeration. Quarterly or monthly visits, coil cleaning, gasket and defrost checks, priority dispatch on down equipment, and consolidated reporting for multi-site operators. Priced per site after a walkthrough.
