Frequently Asked Questions
As a Pasadena homeowner, my sewer line is backing up. Could local tree roots be the cause, and how do you handle it?
Yes, tree root intrusion is a very common sewer issue in Pasadena due to our mature landscaping. Our technicians use electronic inspection cameras to locate the exact point of blockage or damage. Depending on the severity, we can clear the roots with specialized equipment or, if the pipe is compromised, perform a precise repair or replacement to restore proper flow and prevent future problems.
I need a new water heater installed. What does your process involve to ensure it's done correctly?
Our process starts with assessing your home's specific hot water needs and the existing setup. Our licensed plumbers handle the full installation, including safe disconnection of the old unit, proper disposal, code-compliant installation of the new water heater, and thorough testing for leaks and performance. We also explain your new system's operation and maintenance to ensure your long-term satisfaction.
My HVAC system isn't cooling properly. Do you offer repair services, or is replacement usually necessary?
We always start with a comprehensive diagnostic to determine the most effective and economical solution. Many issues, from refrigerant leaks to faulty components, can be repaired. If the system is very old or inefficient, a replacement might be the better long-term value. We'll provide a clear, upfront assessment and explain all your options so you can make an informed decision for your home and budget.
