"James was great! I would hire them again. He replaced all four outdoor lights as well as shifted a wall thermostat so it wasn’t in the middle of our wall. He spent the extra time needed to get the thermostat done as well as run two separate times to Home Depot to get the equipment he needed. And the price they set was the price I paid as they didn’t charge me additional for the extra time. Thank You! (LOL - water heater wasn’t done, it was the only choice)"

"If you care about the safety of your kids and pets don?t used them for heating and cooling! We hired Apex to install a new furnace and thermostat in December. The installation seemed fine at first. But when we left town for a few days and left the air conditioning on for our cat, we came back to a nightmare. The heat was running at full blast and the house was well over 100°F. It was dangerously hot?this could have killed our cat. This wasn?t a small mistake. It was a serious failure, either in how the system was installed or configured. There was no warning, no alert?just a sealed-up house baking in extreme heat. If you care about the safety of your pets or children, I strongly recommend you do not use Apex for heating and cooling. When I called to report it, they acted like I was an inconvenience. I was told ?someone might call back,? and that was it. No urgency, no concern, no accountability. We trusted Apex with our home?s climate system. What we got was negligence and complet"

"It was great I used Greene Plumbing. Matthew called after I submitted to Angi and gave me a price over the phone. I got several other quotes but Greene price was very competitive and got me scheduled for the next morning. The work was completed and his work was excellent. He was very thorough and explained all the work and reviewed with me before he left. If I need a plumber again I will definitely use them."

FAQs for water heater repair or service projects in Lancaster, OH

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.
