"Fred was wonderful. He converted my new stove/range from Natural gas to propane. In the process, he fixed the gas lines coming from outside the home to the range. Even though it was a small project, he was out very quickly after my call. I expect to be hiring Meredith Plumbing and Heating again for a different project."

"He started great, but went down hill. 5 months to install a new heating system after being told it was 5-6 weeks.I was told he had no idea when he could finish because he started a 92 unit condominium project. On another project they installed an HVAC system with no control board. Lied to continuously about dates. We paid in advance for the work and found out afterward that he fired half the staff (I now know why.) Rather than be upfront about the issues he was facing we told lies. Very frustrating and found Devin to talk like an excon. Say one thing and do another with a very straight face."

Gas Leak Repair questions, answered by experts

The size of a pipe isn’t always the outside or inside diameter. Rather, it’s a nominal diameter that depends on the type of pipe. For male pipes, you’ll need to measure the outside diameter. For female pipes, you’ll need to measure the inside diameter. You’ll then need to use a nominal diameter conversion chart to get the actual pipe size you’d buy in the store.

If you sense a gas leak or are upgrading your appliances, it’s best to hire a gas engineer to disconnect the gas stove for you and conduct any other necessary inspections and repairs. While it is easy to disconnect the gas stove yourself, you may not be qualified to complete what needs to be done next. Gas is also harmful to the human body. Therefore, a trained professional is more suitable to handle any gas-related problems.

Yes, flexible tubing and high-efficiency gas lines are options for new installations.

Take this one seriously! If your oven smells like gas when it’s off, this is a telltale sign of a gas leak that can lead to a fire or explosion. In addition, a small leak has the potential to turn into a major leak without warning if any part of your piping or tubing breaks. Potential sources of a leak include the gas valve, burner, joint, or connection lines behind the stove. If the leak appears to be significant, you should contact the gas company or fire department.  

Yes, it’s possible to convert an oil furnace to gas. However, you may have to replace the furnace completely instead of simply converting it. If the original oil furnace has had any type of damage or is older (typically considered over 15 years old), then you will likely need a full replacement versus a conversion.
