It is our mission to provide excellent workmanship and complete customer satisfaction from start to completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer.

"We recently discovered a plumbing leak from the last freeze that had gone unnoticed on our outside water spigot, and unfortunately the water had been leaking into our garage. Joseph from Vortex Plumbing Solutions came out right away and got everything taken care of quickly and professionally. What really stood out was his follow-up during the recent freeze. He reached out to make sure our pipes were properly covered and even offered to swing by to check on everything if needed. That level of care and customer service means so much. We truly appreciate the responsiveness, professionalism, and peace of mind Joseph and the Vortex Plumbing Solutions team provide. Highly recommend!"

Your trusted advisers for AC repair, furnace repair, plumbing and electric in Austin, Texas. Fox Service Company is a local heating and air conditioning, plumbing and electrical company that has been in existence since 1972. As a family oriented company, we employ local team members committed to providing the highest quality service. We service the greater Austin, TX, Metro area, including all of Georgetown, San Marcos and Round Rock, Texas.

"PAID $14,000 for an Lennox system ONLY 2 YEARS AGO. Fox installed and serviced it. Recently, system stopped working and a Fox tech charged us $320 to fix. It stopped working 3 days later, so they came out again. Then, they wanted $3244 to replace the coil. NEVER buy Lennox (look up the class action lawsuit RE coils). NEVER use Fox (I've been pushed up to a "supervisor" 4 times with no resolution, the last one has yet to call). Lennox system's have faulty coils (see Reddit). Fox says they NOW don't use Lennox. (Head scratch) You make the connection. So, all I asked for was a new coil installed (part covered under warranty, 7 yrs left) and a guarantee that if it failed again (meaning I'd pay this time and have seven TX summers to go), Fox would not charge me for labor ($3244...pretty steep price too)...no call back."

"I really needed my outside faucet replaced, it was not working properly and was very hard to turn off, to prevent leaking. I called Excalibur Plumbing and they sent Curtis out to fix my issue. He was very friendly, courteous and easy to work with. I use this faucet a lot in the summer time to water my flower bed and my yard. It's now working better than ever! Thanks Curtis!"

FAQs for water heater repair or service projects in San Marcos, TX

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
