HVAC and Generator FAQs

Browse our comprehensive FAQ to learn about HVAC maintenance, electrical safety, and system troubleshooting. 3RM’s answers help Fort Gibson homeowners make informed decisions and keep their systems running smoothly.

  • What regular maintenance does my HVAC system need?

    We provide residential, commercial, and emergency electrical solutions, including wiring, panel upgrades, lighting installation, and troubleshooting.

  • Why is my heater blowing cold air?

    There are several possible reasons:


    • The thermostat is set to “cool” or “fan only”
    • The pilot light is out (for gas systems)
    • The air filter is clogged
    • The system is still warming up

    If the issue persists, it’s best to call a technician to diagnose the problem.

  • What’s the difference between a furnace and a heat pump?

    A furnace generates heat by burning fuel (usually gas or electricity).


    A heat pump transfers heat from outside air into your home and can also cool in summer.


    Heat pumps are more energy-efficient in milder climates, while furnaces are better for extremely cold areas.

  • What size heater do I need for my home?

    The right size depends on your home’s square footage, insulation, ceiling height, and other factors. An oversized or undersized unit can lead to inefficiency and higher energy bills. We offer free in-home assessments to help you choose the perfect system.

  • How often should I replace my air filters?

    Replace standard filters every 1–3 months and high-efficiency filters every 3–6 months to prevent airflow restrictions and dust buildup.

  • Why is my circuit breaker tripping frequently?

    Frequent trips may indicate overloaded circuits, faulty wiring, or a malfunctioning breaker—schedule an electrical inspection to identify and fix the issue.

  • When should I consider upgrading my electrical panel?

    If your home frequently experiences breaker trips, flickering lights, or you’ve added new high-power appliances, panel upgrades ensure safe, adequate power distribution.

  • What causes uneven heating or cooling in my home?

    Uneven temperatures often result from clogged filters, improper duct design, or failing components—airflow inspection and balancing can resolve these issues.

  • How can I improve my home’s energy efficiency?

    Upgrade to a programmable thermostat, seal duct leaks, insulate properly, and schedule regular maintenance to enhance efficiency and lower utility bills.

  • Is an HVAC system tune-up really necessary?

    Yes—annual tune-ups prevent costly breakdowns, extend system lifespan, and optimize performance, saving you money in the long run.

  • How do I know if my wiring is outdated?

    Outdated wiring often shows signs like flickering lights, discolored outlets, or frequent breaker trips—consult a professional for a thorough electrical safety inspection.

  • Can I perform HVAC repairs myself?

    DIY repairs can be risky and may void warranties—leave complex tasks like refrigerant handling and electrical work to certified HVAC technicians.

  • How long do heaters typically last?

    Most modern heaters last 15 to 20 years with proper maintenance. However, older units or those that haven’t been regularly serviced may need replacement sooner.
