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

The cost of repairing a gas leak depends on the type of leak, its severity, and how difficult it is for the repair technician to reach it. Some of the most common gas line repair costs, on average, include:

  • Cap a gas line: $75–$150

  • Gas system inspection: $150

  • Pressure test: $75–$500

  • Damaged or corroded pipe: $6–$7 per linear foot

  • Repair gas leak: $120–$5,000

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

A few potential problems can cause your gas grill to stop working:

  • Burners aren’t properly aligned.

  • Food debris is clogging the burners.

  • Hose connections may be blocked.

  • Burners may not be getting enough gas.

  • Gas valve is not working properly. 

If you’re experiencing any of those problems with your gas grill, hire a local grill repair professional to inspect your grill for issues and implement a plan to resolve them.

Most qualified local plumbers in your area should be able to help with this job. However, it's always best to check with your utility company before starting any gas-related project. Speak with them about your needs and request recommendations for licensed plumbers who can pull permits and properly install the line.

Yes, it can be worth installing a gas fireplace, depending on your home heating needs. The cost to install a gas fireplace can be much lower than the cost to install a comparable wood-burning fireplace. The convenience of starting a fire with the flip of a switch and turning it off just as quickly makes a gas fireplace a big time saver over starting and maintaining a wood-fueled fire. A gas fireplace also does not require ash cleanup or frequent chimney cleaning to remove creosote and other buildup that can lead to chimney fires. Gas fireplaces burn and heat much more cleanly than wood fireplaces.
