What To Do When Your Central Heating Isn’t Working?

If your central heating isn’t working, there are a few things you can do to troubleshoot and get it working again. Most people try to delay the repair service, but delaying will only complicate the issue and make the repair service more expensive in the longer run.  Contact  our heating repair in Louisville to inspect the system and fix the issue with ease

Steps To Troubleshoot Your Central Heating System!

If your central heating system is having trouble functioning appropriately, here is how you can troubleshoot it and try to fix it: 

  • Check The Thermostat

Ensure the thermostat is set to heat. If you don’t see any lights on and can’t manually adjust the temperature, ensure the power is on. If you’re still not seeing any lights, try replacing the batteries in your thermostat; if that doesn’t help, it may be time to call the technicians at C&L Heating and Air for an inspection or heating repair in Louisville.

  • Check The Pilot Light

The pilot light is a part of the ignition system and helps to start the combustion process to produce heat. The pilot light should be blue; contact our professionals if it burns yellow or orange. If the pilot light is turned down, you should refer to the furnace’s manual to re-ignite it again. 

  • Use A Radiator Thermometer

Use a radiator thermometer to check all of your radiators for temperature. If they’re too hot or too cold, it may mean that there’s an issue with some of your pipes or valves that need to be fixed before you can get the central heating system operating at total capacity again.

If you notice water pooling around one of your radiators, something likely needs repair or replacement immediately, call us for heating service in Louisville immediately!

  • Cold Radiators 

Here’s how you can fix the boiler system if the radiators are cold: 

  • Check the heating system’s emergency switch to make sure it is on.
  • Bleed the radiators to remove any air pockets that may be blocking the flow of hot water.
  • Check the pump to make sure it is functioning properly.
  • Check the valves on the radiators to make sure they are open.
  • Check the boiler to ensure it is functioning properly and that there is enough water in the system.
  • The Buildup Of Rust And Sludge

The best way to get rid of rust and sludge is to use a pressure washer to clean out any clogged pipes so they can start flowing again without interruption. Check for damage, flush the system, and use a rust inhibitor to prevent further corrosion. If there is corrosion, maybe it is a sign you should call us for heating services in Louisville to replace the unit. 

  • Water Gurgling

The first step toward fixing this problem is ensuring there aren’t any leaky joints around where water enters or leaves your home. It is better to switch off the system and call the experts to look at it.
