Boiler Repair in St. Louis Includes:

While we encourage homeowners who don't know the ins and outs of boiler repair, Weis Heating & Cooling provides a basic checklist below for reference. Our HVAC maintenance plans are much more detailed, of course, but here's an idea of what to keep in mind when you contact us for more information:

  • Leaks, Pumps & Valves: Any leaks can lead to bad pressure in your pumps and valves. There are several ways to check gas and water pressure in your system. One way to avoid any boiler installation issues is to make sure your system is clean and maintained. This can also improve the health and safety of your home.
  • Temperature Settings: The temperature your boiler is set at is important as well. Water too hot? Turn it down. Too cold? Turn it up. Maintaining water temperature is doubly important when your boiler controls your home's heating.
  • Safety: One priority when repairing or installing boilers is to check fuel cutoff points. We highly recommend hiring experienced, qualified technicians to monitor a gas boiler's fuel consumption.
