If you know how small problems with your HVAC system can grow quickly into bigger problems, you may be ready to call for repairs as soon as you can. However, while that is a good rule to have, there are a few things you can do before you call for repairs. That way, you can rest easy knowing that you didn’t call for help for no reason. Sometimes, we can make mistakes and come to conclusions before we inspect things and know all the details. Here are 5 things you can check before you call for repairs for air conditioning system service in Potomac.
Change the Filter
If your filter gets too dirty and blocked up, it can reduce the volume of hot air that gets blown out and even cause your furnace to shut down completely. This can reduce efficiency and the lifespan of your furnace. Check the air filter every one to three months and replace it if it’s dirty to keep your furnace functional and avoid needing to call for unnecessary air conditioning system service in Potomac.
Check Your Thermostat
If your furnace isn’t switching on or seems to be blowing less than an adequate amount of hot air, you may want to check your thermostat. To test and fix it, make sure your thermostat is set to heat. Set it to five degrees above room temperature (to see if the furnace comes on), check and replace the batteries if needed, and open the panel to blow away any loose dust and debris.
Check Your Ducts
If your problem is a few cold spots in your home, the issue may be with your air ducts. Check to make sure there is no blockage in your ducts and, if that doesn’t seem to be the problem, ensure that there are no cracks or leaks that require sealant.
Make Sure the Blower Motor Panel Is Shut
If the last time a repair was made, your blower motor panel was not shut properly, a safety device may prevent your furnace from turning on. Make sure the panel is shut, and then test your system. If that doesn’t work, call for air conditioning system service.
Make Sure the Gas Valve Is Open
Similar to the blower motor panel, if the gas valve was turned off during a repair, no gas can enter the furnace, and so there’s nothing to burn to create heat. Turn it back on and test it to see if that solved the problem.
