Inspection-summary reviews from San Gabriel Valley Basin + East/Northeast LA River Corridor homes
Each review is also emitted in the page JSON-LD with a 1:1 match between visible and structured-data text. Author names use first name and last initial only, and ratings reflect the actual review (some 4-star reviews are included where homeowners flagged a real complaint that was resolved).
Sewer backup on a Sunday at the Aldama Square rental. Tech was there in 90 minutes, pulled the cleanout, ran 60 ft of cable, cleared the blockage. Camera follow-up Monday showed grease buildup that he flagged for a hydrojet. Communicated with my tenant the entire time. The repeat-stoppage history made me ask for the camera, glad I did.
Eight Halo recessed cans in the living room ceiling and a new pendant over the dining table. The recessed install was great. The pendant box had to be relocated about 10 inches because the original was offset, and the resulting drywall patch is fine but you can see it under raking light. They offered to come back for a second skim coat. Lights themselves work perfectly.
Compressor was short-cycling on a Sunday afternoon in the Mission 261 area of Alhambra. Tech showed up with a manifold set, measured superheat of 12 and traced it back to a failing TXV on the evaporator coil. EPA 608 certified handling on the R-410A recovery, paperwork was clean, and the 4-ton condenser has run quiet since. He explained why the prior shop missed it.
Questions homeowners ask before booking
Why does Circuit & Cistern LA check air, power, and water together?
Older SGV and Northeast LA homes often have connected constraints. A heat pump may need panel capacity, a water-heater change may need venting or electrical work, and an AC leak may be condensate plumbing rather than refrigerant.
Is the booking form on this site?
No. Booking uses the external scheduler at https://nexfield.pro/crm/book?u=205. The site does not create a fake internal booking form.
What hours do you answer the line?
Standard dispatch is Monday–Friday 7:00 AM to 7:00 PM and Saturday 8:00 AM to 4:00 PM. After-hours emergency triage available 7 days a week for active leaks, sparking panels, no-cooling, no-heat, and gas-appliance concerns.
Do you publish a contractor license number?
License documentation is shared during the booking flow once a scope has been agreed. Inspector-facing paperwork (LADBS, Pasadena Permit Center, LA County Building and Safety) lists the responsible licensed contractor for the specific permit pulled.
