FAQs We’ve Got Answers to Your ​Furnaces Questions
  • Most companies will recommend furnace replacement when the cost to repair your system is more than half the cost of a new system. At times, a repair won’t restore the heating system to a minimally effective level. The lifetime for most furnaces is 15-20 years, and so replacement is generally recommended during that time frame. For more considerations, visit our blog covering more details on when to repair or replace your furnace.
  • This could be because of improper thermostat settings. Check that the fan blower is set to “auto” and not “on.” Other causes include a damaged pilot light, restricted airflow due to dirty or clogged furnace filters, or blocked condensate lines. If issues persist, call Peachtree Service Experts for prompt repair.
  • Your home’s air filter should be changed routinely, typically every 30 to 60 days.
  • We service many types of heating systems, including gas furnaces and heat pumps.
  • Keeping your systems maintained will help bring costs down. Check our helpful in-depth information about keeping your systems healthy. This will tell you about proper maintenance and why it’s important.
