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

Most likely, a gas plumber would be the best pro for many components in your home, and you might not even realize it. Natural gas plumbers are responsible for maintaining and installing natural gas lines, including installing appliances that use natural gas. These can include:

  • Fireplaces

  • Water heaters

  • Furnaces

  • Hot tubs

  • Clothes dryers

  • Ovens

  • Outdoor grills

Gas plumbers are also the pros that would handle a natural gas leak in your home, so it's essential to know the signs of a gas leak before it becomes a dangerous situation.

Yes, it’s possible to cap a gas line yourself if you’re no longer using it or are simply going out of town for an extended period of time. It’s essential to follow the steps on properly capping a gas line yourself. If you’re uncomfortable with any of the steps, you may want to bring in a natural gas plumber for added reassurance.

Running a natural gas line costs between $260 and $820, with an average cost of $540. Gas line repairs cost between $15 and $25 per linear foot, and the cost depends on the type of fittings and connectors, the piping needed, and the mounting hardware. The pipe’s location also matters as it will take more time and labor to access underground pipes than aboveground pipes.

It's not hard to replace a gas line, but it requires a pro’s knowledge and expertise. Replacing a gas line becomes more time-consuming and costly if you need to excavate the area to access a gas line underground.

Plumbers typically install gas lines. When hiring a plumber, you should make sure that they have the proper licenses and credentials. While you can hire any plumber to complete this task, you may consider hiring a natural gas line plumber who specializes in moving gas lines. They’ll have extensive experience completing similar projects.
