“He ended up recommending equipment that is much stronger, more efficient (DC vs AC), and it is seamlessly integrated with the rest of our smart home.”- Thomas B.
“Quick and Honest Work”
My wife had started the process of getting bids for a new AC system on the house. The bids she was getting were pure insanity. We had American Plumbing out to do our tankless water heater, and I knew they did AC. I also had Nick from American out earlier to our house to replace a capacitor on our old failing system, and he was quick and honest about the job. I wanted to hear his take on our job. He ended up recommending equipment that is much stronger, more efficient (DC vs AC), and it is seamlessly integrated with the rest of our smart home. All for about $8k less than the other bids we were getting. I even got a roll-around AC unit for my garage/shop as part of the deal.- Thomas B.
Side bonus. My hummingbirds no longer fly away the second the AC fires up. -

“Service Was Brilliant”
American Plumbing Hvac came over to remove my furnace after my water heater leaked and created a flood. Andrew and James arrived on time were prompt and quickly removed the furnace. They both need raises! They were great gentlemen and the service was brilliant!- Kathy H. -

“They were amazingly efficient, friendly, professional, and even re-inspected their own work to make sure everything was 100% perfect.”- Chris A.
“Perfectionists!”
This company was referred to us by another plumbing contractor in San Diego.. so that says something right there. Justin came in and handled our laundry list from our home inspector. He reviewed all the work, the charges associated with it and helped to navigate what really needed to be done. They were amazingly efficient, friendly, professional, and even re-inspected their own work to make sure everything was 100% perfect. This is a high-quality company offering great services and fair pricing on all work performed. We are excited to have found our new local plumbers for any and everything in our home- Chris A. -
“I will ALWAYS use them for my plumbing needs and refer them to friends and family!”- Leslie W.
“Great Customer Service”
We had plumbing issues at THE worst time, Friday after 5 pm! We had a leak coming from the toilet in our only bathroom. We called 4 plumbing companies and the only one that got back to us that evening was American Plumbing. They offered to come out that evening but Saturday morning was best for us and we were their first appointment! Ozzie Garcia was the technician that came out and he was great! Then Sunday afternoon we had an issue with our main water line and again, American Plumbing and Ozzie Garcia came to our rescue!! Both times they called back in a timely manner and took care of our plumbing issues right away. Ozzie is professional, courteous, timely, and has great customer service!! I will ALWAYS use them for my plumbing needs and refer them to friends and family!- Leslie W.
