Look What Our Clients Say
Fast response, honest pricing, and work done right the first time — that's what our clients appreciate most.
"Our 13 year old tankless died over New Years. Contacted LA Water Heaters and they were out early the next day to put in a new and improved one. Very knowledgeable, courteous, professional and fast. Can't recommend more highly."
"Our water heater broke, and the LA Water Heaters team was out two days later installing a new one for us! We are so grateful for their knowledge and expertise as they helped us choose the right solution."
"Our water heater went out and when I inquired on Yelp they were very responsive. They reached out, gave me a quote and had the new unit installed the next day. They even hauled away the old unit and the housing it was in."
"LA Water Heaters did a fantastic job installing a new Rheem water heater. Proficient, efficient, and comprehensive from start to finish. I'd use them again without hesitation."
"LA Water Heaters may be my new favourite plumber! Their crew came on time and installed the water heater quickly and cleanly. Fair price and great communication throughout."
