FAQs We’ve Got Answers to Your Heating Services Questions
  • We’ll do an in-home consultation, work with you to find the best heating system for your needs, perform the installation and also check that the system is working before leaving.
  • It’s common for your heating and cooling equipment to make a little noise. However, hearing odd or loud noises could mean there’s an electrical problem or trouble with the blower fan or capacitor. If not fixed, there can be serious (or expensive) consequences later on.

  • A popping disturbance is a common sign of an insufficient duct design. This occurs when there’s more airflow than your ductwork can manage.

    Troubles with your ductwork can lead to other ventilation and air quality troubles, such as:

    • Significant noise
    • Greater energy needs
    • Early system malfunction
    • Irregular heating and cooling
    • Broken AC compressor in the summer
    • Too hot furnace or heat pump in the winter
    • Mold growth inside ducts

    Call a qualified company in the U.S like Peachtree Service Experts to examine your home’s ventilation system. We can offer suggestions for duct repair or installation.

  • If you want to include heating tune-ups with other important services, consider signing up for our Advantage Program™, which can help keep your warranty in good standing.
