"Of course, my A/c failed on one of the hottest days in July. Frankie made it to my house in the afternoon the next day, not bad by any means knowing it is a busy time. Repair was quick as it was just the capacitor. Cost wise, a little high based on my neighbor that had same problem a few weeks ago. My bill was $450- (150 service call, 300 for capacitor) neighbors company charged $275 for same service. These capacitors only cost $20-30. Perhaps service tech was in a hurry and did not want to list the other categories such as diagnostic fee and repair labor and just added those costs to the part price."

FAQs for water heater repair or service projects in Caldwell, ID

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.
