"Last October, my sister, an elderly veteran living alone, contracted Genie Bath Systems to remodel her master and guest baths. She was diagnosed cancer and passed before the remodel was complete. Which, to be fair as we were not able to work with Genie while attending to my sister. The contract was expensive. Very expensive. The cost of the remodel is close to 1/4th the value of her home. I noticed there were issues with the remodel that showed a surprising lack of attention to detail. Genie sent people to address the issues twice. Yet issues remain. My calls to my contact at Genie are now being ignored. Also, the only document I have for the remodel is the contract my sister signed. It is not detailed. I have and continue to ask for a breakdown of the cost. An estimate or work order. This request is also being ignored. I am disappointed and have to wonder why Genie will not provide this information. I have several other questions for Genie that I will not go into here. But based on my experience, I cannot recommend Genie. In fact I would warn anyone considering Genie to be very careful about the cost of the contract."

We are proud to be San Antonio's largest residential heating and air conditioning contractor. From the moment you call until the job is done, our goal is your 100% satisfaction. If the job is not done right, we will make it right.

"UPDATE: Amazing how this wonderful review has turned to wishing I never left it or could give them 0 stars. The initial sale was amazing (should’ve known it wouldn’t last). We spent 30k on a brand new unit. 1.5 year later and we find ourselves on day 8 without an AC, now being told it may be another week “and if we don’t hear back from them by Friday, for US to call them again”. Do not be tricked by their initial caring demeanor. It obviously doesn’t seem to last. I have health issues, we have 2 senior dogs and are in Texas. It’s been pushing 90 degrees in our home and they can’t provide a solution to a ‘Cadillac of units’ that THEY recommended and we fell for. I am at a loss. Jon Wayne is the company that installed the unit, now they’re saying the unit ‘is grounded’ and ‘is like a heart that stopped beating’. Crazy that it’s supposed to be a top of the line unit that they compare to a Cadillac for the AC world, yet it stopped functioning after a year. Do yourself a favor and get other options and opinions before trusting them on something as important as cool air in your home. I can’t believe we are dealing with this. Now we’re 30k in, an additional 1k for their ‘warranty’ and still without a working AC. WOW."

FAQs for water heater installation and replacement projects in La Vernia, TX

You'll need an expansion tank if your home has a closed water system, which is standard in newer homes or those with backflow preventers or pressure regulators. Expanding hot water has nowhere to go in closed systems, creating potentially damaging pressure. The expansion tank provides space for this expanded water, protecting your plumbing system and water heater from premature failure. Many local building codes now require expansion tanks, and some water heater warranties may be voided without one.

For a standard 50-gallon water heater, a two-gallon expansion tank is sufficient. This sizing assumes normal household water pressure between 40 and 60 psi. If your home has higher water pressure (60 to 80 psi), consider upgrading to a slightly larger tank for added protection. The expansion tank's purpose is to accommodate the increased volume that occurs when cold water heats up, which is proportional to your water heater's capacity.

Watch for signs like dripping water around the tank, fluctuating water pressure throughout your home, or unusual noises in your plumbing system. A properly functioning expansion tank should feel light when tapped on the bottom—if it feels heavy or waterlogged, the internal bladder has likely failed. Other indicators include frequent triggering of your temperature and pressure relief valve, visible corrosion on the tank, or unexplained increases in your water bill, suggesting hidden leaks.

Most expansion tanks have a service life of five to 10 years, though some may last up to 12 years or more with proper maintenance. Factors affecting lifespan include water quality, system pressure, installation quality, and tank construction. Hard water areas often see shorter lifespans due to mineral buildup. Regular maintenance checks can help identify potential issues before complete failure. When your water heater is due for replacement, it's wise to replace the expansion tank simultaneously, even if it hasn't failed yet.

A 30-gallon water heater needs an expansion tank if your home has a closed plumbing system. The need for an expansion tank is determined by your plumbing system type rather than water heater size. Even smaller water heaters create thermal expansion when heating water. If your home has a backflow preventer, pressure regulator, or check valve on the main water line, you have a closed system that requires an expansion tank. Check your local plumbing codes, as many jurisdictions now mandate expansion tanks regardless of water heater size.
