"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."

At S&E Cataldi Heating & Air Conditioning we work hard for your comfort. Over a decades of study and experience have taught us that the right heating or cooling system can improve health of a house and the poeple who live in it. We're serious about comfort, because proper moisture balance means that you will breathe easier and the wood in and out of your home--including your antiques--will be well protected. Chronic moisture balance problems affect "leaky" buildings, making them difficult to dehumidify in summer and heat in the winter. The first line of defense of course, is proper insulation. Clover HVAC technicians are certified insulation and air seal specialists who can do a thorough analysis of the penetration points in your house and stop air leaks cold. Buildings are like the people in them. Both need the right balance of moisture in the air. People have their own natural cooling system--the ability to sweat. Houses need help. S&E Cataldi can set a heating and cooling system's balance to properly regulate interior air. The result? A structure that isn't so dry the wood is cracking or so moist there is rot, and inhabitants who won't develop skin problems from excessive dryness or allergic reactions to mold and mildew.

Gas Leak Repair questions, answered by experts

While some building codes allow galvanized pipe for natural gas, it shouldn’t be used for propane. Propane can cause the pipe to wear down, leading to dangerous leaks. Instead of galvanized piping for propane, you should consider coated copper, black iron, or corrugated stainless steel tubing (CSST). For underground propane line installation, you can use polyethylene (PE).

Some natural gas furnaces can be converted to propane with a conversion kit, but not all models are compatible. Consult a licensed HVAC pro to determine if conversion is possible and cost-effective for your system. The process involves changes to burner orifices and safety controls, and must be completed to code.

Yes, professional installations typically include safe gas and plumbing connections.

Natural gas companies advise only shutting off the gas supply at the meter yourself if you smell natural gas or suspect there is a leak, typically following an emergency. Instead, you can shut off gas to individual appliances when necessary. If you want to turn off your natural gas entirely, you should contact your utility company. You’ll generally also need to acquire a permit to work on your natural gas line.

You may want to remove the gas line if it’s unsightly or if it’s causing a problem with future appliances. The downside is if you decide to go back to gas, you would need to run a new gas line to the area.  The average cost to run a new gas line is $550, but the installation can range anywhere from $120 to $1,350.
