Frequently Asked Questions

  • How often should I change my HVAC air filters?

    For most homes in Georgia, we recommend changing filters every 30 to 90 days depending on pet ownership and indoor air quality needs.

  • Why is my air conditioner freezing up?

    This is usually caused by restricted airflow (dirty filters) or low refrigerant levels. Turn the system off and call us for a diagnostic.

  • What are the signs that my furnace needs repair?

    Look for odd noises, frequent cycling, a yellow burner flame, or a sudden increase in your monthly gas or electric bill.

  • Should I repair or replace my aging water heater?

    If your unit is over 10 years old or the tank is leaking, a replacement is often more cost-effective than frequent repairs.

  • Why do my circuit breakers trip frequently?

    This often indicates a circuit is overloaded or there is a short in the wiring. It is a safety risk and should be inspected by a licensed electrician.

  • What does a seasonal tune-up actually include?

    Our tune-ups include cleaning coils, checking electrical connections, testing safety controls, and optimizing refrigerant or fuel levels.

  • Do you offer 24/7 emergency services?

    Yes, we provide around-the-clock emergency support for critical HVAC, electrical, and water heater failures.

  • What are the benefits of a tankless water heater?

    Tankless units provide endless hot water on demand and are significantly more energy-efficient since they don't maintain a large tank of hot water.

  • How can I lower my monthly energy bills?

    Regular maintenance, installing a smart thermostat, and upgrading to high-efficiency equipment are the best ways to reduce consumption.

  • Is JML Heating, Air, and Electrical licensed and insured?

    Absolutely. We are fully licensed in the state of Georgia and carry comprehensive insurance for your peace of mind.
