"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"Great service and work from Miguel and team. I would hire them again. What originally was a slow draining sewer line turned into a root infested backup. Miguel was able to scope the drain and visualize the root of the problem. They were prepared to start digging and had the tools and supplies on the truck to get the job completed. He clearly explained the discovery, repair, and installation process as well as potential other root intrusion spots. After the dig, the soil and grass was replaced and can hardly tell that any work was done. They also cleaned the dirt/mud on the concrete walk way. Thank you Miguel and team for the great work."

"I bought a hot water heater to replace the one that calcified due to Anaheim water. Technicians : Marty, Parker and Shane were excellent. I would recommend this company RT Olsen Plumbing Heating and Air Conditioning. They took out my old water heater and halled it away. The new water heater was installed with no problems. I Gave this company and there excellent crew 5 Star"

"As expected, I got bombarded with several texts/calls/Angi messages as soon as I requested a Water Heater replacement. I waited for a human to leave a message instead of automated systems, which was Paul at Complete Plumbing located in Claremont. Same day replacement, haul away, and install of a 40 Gal. Bradford White was $1595 (2 year labor water, 6 year manufacturer warranty). Michael did the installation and had a delay from the first job, but Paul kept updating status and the install time wasn't much later than the original estimate. Michael answered all my questions and concerns."

The 7 workers that were involved at various times all seemed to be well trained. Michael I, the lead plumber, is very intelligent, knowledgeable, and good to work with. Very nice people all around."
