"HPC quickly determined and resolved the cause for our problem in August. However, they also determined that we had a relay that needed to be replaced. They informed me that it would take some time to get the relay, I think they mentioned delays due to the tariff situation. They promised to get back to me when the relay came in. They jury-rigged the system to work properly without the damaged relay, but warned me that the jury-rig would malfunction badly if we switched from cooling to heating. Starting in November, we called HPC a half-dozen times over several weeks asking for the status of the replacement relay. We were told that the appropriate people would be informed, and that they would call us back with the requested information. On November 11th, I sent an e-mail containing the same information. This resulted in a response containing an estimate for something called a "heat kit". When I asked whether the "heat kit" contained the replacement relay, I got no response. "

"Jimmy showed up to my home during a time when my thermostat was not working. That issue was fixed. He sold me a services contract and told me when he returned to services the units, he will cover the pipes outdoors. I purchased the contract for twice per year maintenance. I scheduled with him for a specific date. Appointment was confirmed but Jimmy did not show. When I called, he it appears that he forgot my appointment and he rescheduled saying he could not work in the rain. He rescheduled for a few days after and one of his workers showed up (Carlos). The guy showed up looking like he was someone who does not want to work and unprepared. So, I asked him if he has filters and he said know. Jimmy's workman did not bring filter, so I offered him filters I had stored. I asked him if he bought things to cover the pipes at the back, he said no. I called and left a message for Jimmy. Carlos was so rude and unprofessional. I was so scared of him and the way he was behaving. Carlos then said he would NOT do any service. IT WAS A WASTE OF MY TIME. He did return my money. BUT I will not recommend him. Will NOT use him again. As woman I will not hire again. Customer services was poor, reliability and punctuality poor."

FAQs for water heater repair or service projects in Rockville, MD

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.
