Plumbing and HVAC in Ontario, CA 91761
36 providers listed in Ontario, CA 91761 for Plumbing and HVAC: 18 companies and 18 independent tradespeople. 36 licensed.
Every business here holds a current licence, shown on the listing so you can check it yourself.
Some states license the person rather than the firm (master plumbers, gas technicians), which is why independent tradespeople have their own tab.
Badges come from public records, not from us or the business. Licence verified: an issued licence number and a city permit record name the same firm. Established: ten or more permits on record. Active this year: a permit dated in the last 12 months. A business without a badge may simply work where we hold no permit records. San Diego County permit records here run to April 2025, so a business known only from those records cannot carry Active this year.
Also in 91761: verified permit history, trade unconfirmed
These businesses pulled permits that Orlando and San Diego County recorded, but the permit records do not establish which trade they work in, so we do not file them under one. Ask what they do before you ask for a quote.
