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

Yes. There are a variety of standard pipe sizes used in plumbing. The main supply line connecting your home to the street is either 3/4 or 1 inch in diameter. Supply lines are 3/4 inch in diameter. Individual components are 1/2 inch in diameter. Meanwhile, your main drainpipe is often 4 inches wide. Most shower and bathtub drains are 2 inches in diameter, most toilet drains are 3 inches in diameter, and most sink drainpipes are 1 1/4 or 1 ½ inches in diameter.

It can cost anywhere from $200 to $5,000 to repair a gas line. The cost may vary depending on where the problem is located. For example, if there’s a small gas leak somewhere that’s easy to access, the cost could be on the lower side. On the other hand, repairing buried lines and lines in other hard-to-reach areas will be more expensive.

In North America, pipe measurements are listed as the nominal pipe size (NPS). This measurement refers to the outside diameter. As an example, a 1/2-inch copper pipe has an outside diameter of 5/8 of an inch. If a hardware store lists a pipe as having a 2 NPS, it means that all the pipes with this measurement have a 2 ⅜-inch outside diameter, regardless of wall thickness and inside diameter.

Installing a gas line can be extremely time-consuming and dangerous, so you will want to hire a seasoned professional. Perform a thorough search ahead of time to find a reputable and reliable plumber. Pay special attention to licensing and insurance as you go about choosing the best contractor for your needs.

Consider an annual inspection conducted by a local plumber to prevent dangerous and destructive leaks. If you recently moved into an older home or are concerned about the age of your gas lines, call an inspector for a closer look. You may also be required to call an inspector after your contractor installs a new line for an appliance.
