Rooftop package units, split systems and ductless equipment repaired, replaced and maintained for offices, shops, restaurants, wineries and other businesses around Lodi.
When the AC quits in the middle of a Lodi summer, a business doesn’t just get uncomfortable. Customers leave, staff can’t work, and kitchens and equipment rooms overheat. AccuFlow Plumbing, Inc. provides commercial HVAC service under our C-20 HVAC license (CSLB #1025946) for light commercial buildings across Lodi, Acampo, Stockton, Galt and the surrounding area. We diagnose and repair rooftop units and split systems, replace equipment that has reached the end of its life, and keep it maintained on a schedule. We’re a local, family-owned contractor, so you deal with the same people every visit, and the same company can take care of the plumbing in your building.
Most retail strips, offices and restaurants in the area are cooled and heated by rooftop package units (RTUs): one cabinet on the roof that holds the compressor, coils, blower and a gas heat section or heat pump, with ducts running down into the space. We troubleshoot and repair them, from failed capacitors, contactors and fan motors to refrigerant leaks, worn belts, dirty coils, gas valve and ignition problems, and economizers stuck open or closed.
Smaller offices, shops and converted buildings often run on split systems, with a condenser outside and a furnace or air handler inside. For spaces the main system doesn’t reach well, like a server room, a back office, a tasting room or a shop added onto a warehouse, a ductless mini-split adds heating and cooling without new ductwork.
We work on heating and cooling for offices, retail stores, restaurants, winery tasting rooms, convenience stores, shops and agricultural buildings. Each has its own problem: restaurant kitchens load up coils with grease and heat, tasting rooms need steady temperatures for guests and wine, and dusty ag and shop buildings clog filters and condenser coils fast. We set the service schedule around how hard your equipment actually works.
A repair usually makes sense when the unit is in decent shape and the failed part is a capacitor, contactor, motor, igniter or control. Replacement starts to make more sense when a unit is near the end of its service life, needs a compressor or a coil, or keeps breaking down. Units still running on R-22 refrigerant are expensive to recharge because R-22 hasn’t been produced or imported in the U.S. since 2020, so a big refrigerant leak on an older unit often tips the decision.
When replacement is the right call, we size the new equipment to the building and plan the job ahead: rooftop swaps can need a crane lift and a curb adapter to fit the new unit to the old roof opening, and we pull the permit where one is required. We give you the options side by side, with a firm price for each, so you can plan the spend.
Commercial equipment runs longer hours than a home system, so it needs attention more often. We set up commercial HVAC maintenance on a schedule, usually twice a year (cooling in spring, heating in fall), or quarterly for restaurants and dusty buildings. Each visit covers filters, belts, coil cleaning, condensate drains and pans, electrical connections, capacitors and contactors, refrigerant pressures, economizer operation, the gas heat section and safety controls. Owners and managers get a written list of what we found, so repairs can be planned instead of discovered on the hottest day of the year. See HVAC maintenance for what a tune-up includes.
Where we can, we schedule disruptive work like replacements before opening or after closing, and we check in with your manager when we arrive and before we leave. Because AccuFlow is licensed for plumbing, HVAC and general building work, the same team can handle the restrooms, water heaters, grease lines and gas piping in the building. See commercial plumbing.
Estimates are free, and you approve a firm price before any work starts. For maintenance contracts, the price depends on how many units you have and how often they’re serviced.

If I could give Mikey and his team more than 5 stars, I would! We called in on a Friday morning to get our water heater replaced. They had it done by lunch. Quick service, super professional, and quality work you can depend on. Honest team with very competitive rates. No need to get any quotes with anyone else, this is the team you need to handle your HVAC and plumbing.
Had 100 gallon natural gas water heater installed at Skilled Nursing Facility. Accuflow was very communicative and performed the job efficiently with no issues!! They understood that facility kitchen and laundry could not go without water nor gas for too long and took that into consideration and planned accordingly to ensure job was completed as quickly as possible!! Will save in my list of vendors for future services!!
