Who We Are

Downey Plumbing, Heating and Air Conditioning is a family-owned and operated plumbing and HVAC company that has served homeowners and businesses throughout Downey and the surrounding Los Angeles County and Orange County communities since 1930. For more than 90 years, we have built our reputation one service call at a time, by showing up when we say we will, diagnosing problems honestly, and doing the work right the first time.

We hold California Contractor License number 731172, verified through the California Contractors State License Board. We are fully insured, BBB A+ accredited, and 4.8-star rated on Yelp by hundreds of verified customers. We are also highly rated on HomeAdvisor and 100% recommended on Facebook.

Whether you are a homeowner dealing with a plumbing emergency at two in the morning or a property manager planning a scheduled HVAC upgrade, you deserve a contractor who is honest with you, transparent about pricing, and accountable for their work. That is the standard we have held ourselves to since the day we opened.

Our History in Downey

We have been part of this community for a long time. When we started in 1930, Downey looked very different. The homes we serviced then are still standing, and in many cases we are still servicing them today, sometimes for the same families across multiple generations.

That kind of longevity is not something you hold onto by cutting corners. The homeowners of Downey, Bellflower, Norwalk, Lakewood, Long Beach, and the dozens of other communities we serve have always had other options. They have chosen us because they know what they are going to get: a licensed technician, a straight answer, and a fair outcome.

We are proud to be active members of the Downey, Long Beach, Bellflower, Pico Rivera, South Gate, Paramount, and Commerce Chambers of Commerce, and a member of the Commerce Business Council. These are not just listings. They reflect our commitment to the communities we work in every day.

How We Work

Licensed and Verified

Every technician who works under the Downey Plumbing name works under California Contractor License number 731172. This license is publicly verifiable, which means you are never taking our word for it. Our licensing covers plumbing, heating, and air conditioning, so you do not need multiple contractors for different systems in your home.

Fully Insured

All of our technicians and contractors carry full insurance coverage including general liability and workers compensation. This protects you, your property, and your household throughout every job we perform. It also means you are not exposed to liability if something goes wrong during the work.

Background-Checked Technicians

Every technician on our team submits to a full background check before working in anyone’s home. We understand that inviting a contractor into your home requires a level of trust that goes beyond technical skill. We take that seriously.

Continuously Trained

We send our technicians to the Plumbing, Heating and Cooling Contractors School, better known as PHCC, to keep their skills current with the most innovative and efficient service methods available. The plumbing and HVAC industries change, and our team stays ahead of those changes so the advice and service you receive reflects what is current, not what was standard a decade ago.

Fully Stocked Vans

Our service vehicles carry the parts and materials needed for the most common repairs and installations. This means most jobs are completed in a single visit rather than requiring a return trip after sourcing parts. Your time matters, and we try not to waste it.

The 2030 California Water Heater Regulation

One topic we get a lot of questions about right now is California’s upcoming 2030 water heater regulation. Starting in 2030, the sale of new gas-fired tank and tankless water heaters is expected to be phased out in California. This does not make your existing unit illegal to operate, but when your current water heater fails after that date, a direct gas-for-gas replacement may no longer be an option.

We help homeowners understand what this means for their specific situation and plan ahead on their own timeline rather than being forced into a rushed decision during an emergency. Visit our dedicated page on the 2030 California water heater changes to learn more, or call 562-646-1221 to speak with one of our technicians.

Emergency Service, Around the Clock

Plumbing and HVAC problems do not keep business hours. A water heater that fails at midnight, an air conditioner that stops working during a heat wave, or a gas line that gets tagged on a Friday afternoon all need attention right away. Downey Plumbing provides emergency service 24 hours a day, 7 days a week, 365 days a year. When you call 562-646-1221, a real person answers.
