A&A Plumbing has a strong base of loyal, long-term customers who consistently praise individual technicians — particularly Rosendo, Dave, Larry, Germaine, and Mike — for technical skill, problem-solving ability, and courteous demeanor, which drives a solid experience score. However, professionalism is meaningfully dragged down by a recurring and well-documented pattern of no-shows, missed appointments, unreturned calls, and poor front-office responsiveness, appearing across multiple independent reviews spanning 2013 through 2024. Pricing is the weakest dimension: while many reviewers found costs fair or reasonable, a significant minority reported feeling overcharged, encountering arbitrary flat-rate billing, or receiving quotes far above market rate — including one reviewer charged $252 for a five-minute p-trap replacement and another quoted $350 for a faucet install versus a $110 market rate. Project completion scores moderately well when technicians do show up, with most jobs completed fully and a one-year warranty honored in several cases, but the no-show and scheduling failure pattern directly undermines this dimension. The overall score reflects a contractor with genuine technical strengths but serious and persistent operational reliability problems that have cost them customers and trust over many years.
Flags & Warnings
• SCHEDULING AND RESPONSIVENESS PATTERN: At least 10 independent reviews across multiple years (2013–2024) explicitly describe no-shows, missed appointments without notification, unreturned voicemails, and difficulty reaching the office. This is a systemic operational issue, not isolated incidents.
• PRICING COMPLAINTS: Multiple reviews (2016–2021) describe pricing that felt arbitrary, disproportionate to work performed, or significantly above market rate. One reviewer was charged $252 for a p-trap replacement taking under 5 minutes; another was quoted $350 for a faucet install vs. a $110 market rate; a third paid $377 total for a drain unclog and p-trap. One reviewer alleged pricing changed mid-job and felt threatened when questioning the bill.
• BLANK REVIEWS: 7 reviews contained no text whatsoever (only a star rating). These were excluded from dimension scoring as they provide no usable evidence per scoring rules.
• GENERIC SHORT REVIEWS: Several reviews contain only 1–2 sentences with no specifics (e.g., 'Fast and reliable.', 'Very professional and polite.', 'no problems', 'unknown'). These were counted only where they clearly supported a dimension but weighted conservatively.
• POSSIBLE DUPLICATE REVIEW: The review text 'Great company and knowledgeable staff! On time, very efficient and explained every step of the process in full detail. The charges were very fair and reasonable as well. Highly recommend' appears verbatim twice (2021-07-01 and 2022-06-10) from what appear to be different submissions. This may indicate a copied or fake review and was counted only once for scoring purposes.
• RECENCY NOTE: The majority of reviews are older than 12 months, with the bulk of content spanning 2010–2022. Only a handful of reviews are from the past 12 months (mid-2023 to mid-2024). The most recent negative review (2024-06-09) specifically states the contractor 'lost his touch' over the past year, suggesting possible quality decline. Recent data is limited and should be treated with caution.
• ONE REVIEW (2016-04-24) APPEARS TO DESCRIBE A DIFFERENT CONTRACTOR: The review references 'Carlos' as a 'lone proprietor' operating in the Baltimore/Baltimore County area, which is geographically inconsistent with A&A Plumbing in Sunnyvale, CA. This review may have been posted to the wrong business listing and was excluded from scoring.
• IDENTITY INCONSISTENCY: Reviews reference multiple owner names including 'Mike Fox,' 'Mike Gogos,' and 'Carlos,' and reference locations including Sunnyvale CA, Palo Alto CA, Medford MA, Somerville MA, and Baltimore MD. This suggests the review pool may aggregate listings from more than one business operating under similar names, which reduces the reliability of the aggregate score.
Reliability Statement
This WW Score carries HIGH volume confidence due to the large number of reviews, but its reliability is moderately reduced by evidence of possible cross-business review aggregation, at least one confirmed duplicate review, seven blank reviews, geographic inconsistencies across listings, and a persistent multi-year pattern of scheduling failures that suggests the score may overstate operational dependability.
