Spring AC and fall heating tune-ups that keep your system efficient, catch worn parts early and help keep manufacturer warranties in good standing.
Lodi summers regularly top 100 degrees, and that’s exactly when a neglected air conditioner gives out. HVAC maintenance from AccuFlow Plumbing, Inc. is a scheduled tune-up of your heating and cooling equipment by our licensed C-20 team. We clean what needs cleaning, test the electrical and safety components, check refrigerant and airflow, and clear the condensate drain. Most homes need two visits a year: one for cooling in spring and one for heating in fall. We maintain central air conditioners, heat pumps, gas furnaces, ductless mini-splits and boilers in homes and businesses across Lodi, Acampo, Stockton, Galt and the surrounding area.
Before the heat arrives, we check or replace the filter, clean the outdoor condenser coil (valley dust, cottonwood fluff and grass clippings pack it fast) and inspect the indoor evaporator coil. We check refrigerant pressures and the temperature split across the coil, test the capacitors and contactor, measure motor amp draw, tighten electrical connections, and check the condenser fan. We clear and flush the condensate drain and check the float switch, so the drain doesn’t overflow into the ceiling or closet, then confirm the thermostat is reading and switching correctly.
For a gas furnace, we inspect and clean the burners, clean the flame sensor, check the igniter, inspect the heat exchanger for cracks, check the flue and venting, test for carbon monoxide, verify gas pressure, and test the limit switches and other safety controls. We also check the blower and its motor. For a heat pump, we check the reversing valve, the defrost cycle and the backup heat strips. Boilers get their own yearly service; see boiler repair and installation.
Dirty coils, a clogged filter or the wrong refrigerant charge make your system work harder and longer for the same comfort. A weak capacitor caught during a spring tune-up is a quick fix; the same part failing on a 105-degree afternoon is a no-cool emergency. A furnace check is also a safety check, since a cracked heat exchanger or blocked vent can let carbon monoxide into the house. And many equipment manufacturers require regular professional maintenance to keep a warranty in good standing, so keep your service records.
Between visits, check your filter monthly and change it every one to three months, more often during dusty harvest months or with pets. Keep about two feet clear around the outdoor unit.
Rooftop units and commercial split systems run longer hours and usually need service twice a year, or quarterly for restaurants and dusty buildings, with belts, economizers and the gas heat section added to the checklist. We set up scheduled maintenance for businesses and give owners a written list of findings after each visit. See commercial HVAC.
Estimates are free, and anything we find comes with a firm price you approve before we fix it.

I needed a same day appointment and it was needed no problem for them. They explained everything they were doing so i understood with no problem. When the bill came it was very reasonable so I highly recommend this company if you need any work done.
Honestly, these guys are great! They came to my house fast, were courteous and professional. The price was about what I was expecting to pay. I can see why they have a 5 star rating and I will be recommending them to everyone!
