Erick - Oceanside, CA
Needed to have my water heater replaced. Called their customer service like and within 5 mins I had someone coming out for a free estimate. Ignacio arrived looking professional and a understanding of what we’re looking to have done. He took the time to explain the pros and cons to all our questions. To our amazement he was able to install our water heater that day and was done within 2 to 3 hours. The area was clean afterwards and he explain what had been completed. We are new to the area and I believe we could have found our new plumbers.

Ty, our service technician was incredibly knowledgeable and trustworthy. Although we ended needing to replace 2 a/c units, Ty was thorough in evaluating our existing units and explaining all of our options. Thompson will be my first call for future a/c, heating or plumbing issues.
Great service
Kevin - Oceanside, CA
Our technician, Ty called and asked if he could come early to service our A/C unit. We were good with that, and he arrived 20 minutes later. Ty got right to work, but was still able to answer questions. He is friendly and explained everything, a real pleasure to speak with.
