"I had a new HVAC system installed by ( remove company name) which is now Heritage. I called Heritage about a service plan. They said a service needs to be done. I said your company just changed my filter and cleaned the system (literally a week ago). They said only the tech can sign you up so we need to do another service. I said I did not need another service. They insisted. I talked to Chris, one of the service managers and he would not budge. I called again and explained situation. Never heard back. Will not be doing business with a company that does not return phone calls when a customer is begging them to take money for a service plan. Such a poorly run company. So done with them. "

"Our heater stopped functioning on Nov 27, 2023 and we called Petro who had done the maintenance on it before and replaced a motor two years ago. They were responsive and a technician came two days later. He worked for 3 hours without explaining what the problem was. Then said he needed to replace the motor. He fixed the problem and left without much explanation. Two days later a bill of $2500 came via email. No explanation, no break-down. I called 4 times over the last 20 days, spoke to 4 different reps and was promised that a supervisor will contact me with the bill details. Nothing happened. Irresponsible customer service and unprofessional behavior. They show all the symptoms of big, bureaucratic, and indifferent service company. I would not recommend Petro if you have options of more personalized services."

"Frangioso is simply the best. We had a tiny project; we were looking for a quartz remnant for a bathroom vanity countertop and they treated us as if we were purchasing ten times that amount. They went out of their way to meet us when they weren’t technically open, walked us through numerous remnants (they had a great selection) and perfectly installed the countertop. I’m a perfectionist and couldn’t find fault with anything. What amazing service and quality in craftsmanship."

FAQs for gas piping projects in Amherst, NH

Plumbers with proper licensing and credentials install and relocate gas lines. When hiring a professional, verify they have experience with gas systems and all required certifications. Some homeowners choose to work with plumbers specializing in natural gas installations, as they have extensive experience with similar projects and understand the safety requirements.

The timeline for gas line relocation varies based on project complexity, permit processing, and inspection scheduling. The physical labor takes a few hours to one day, depending on the line length. However, the actual installation work represents only part of the overall project timeline. Your contractor should provide a specific timeframe based on your circumstances and local permitting requirements.

Your gas supply must be shut off during the relocation process. This safety measure prevents gas leaks while connections are being modified. Plan for this temporary service interruption by making alternative arrangements for cooking, heating, or other gas-dependent systems in your home. The shut-off generally only lasts for a portion of the work, often a few hours.

Relocating gas lines to connect new appliances is a common reason for this type of project. Whether you're installing a gas stove, fireplace, dryer, or outdoor grill, a professional can determine the best route for extending your existing gas system. The cost will depend on the distance between your current gas line and the new appliance location.

Gas line work is not suitable for DIY projects. Natural gas is highly flammable and potentially lethal if not handled correctly. Gas leaks can be difficult to detect without specialized equipment. Professional plumbers have the proper training, tools, and experience to safely relocate gas lines while ensuring compliance with local building codes and safety standards.
