FAQs

Tunge Heating and Cooling LLC

  • What does HVAC stand for?

    HVAC stands for heating, ventilation, and air conditioning. These systems work together to regulate your indoor climate and maintain comfortable temperatures throughout your home.
  • How often should I change my air filter?

    We recommend changing your air filter every 1–3 months under normal conditions. If you have pets or family members with allergies, you'll likely need to replace filters more frequently.
  • What is a good SEER rating?

    SEER, or seasonal energy efficiency ratio, measures your air conditioner's efficiency—the higher the number, the more efficient the system. Standard ratings fall between 14–16, while systems rated 18 or higher are considered highly efficient.
  • Why does my HVAC system keep turning off?

    Several factors can cause your system to shut off repeatedly. The most common culprits include a clogged air filter, malfunctioning thermostat, or an oversized unit that's short-cycling.
  • What size HVAC system do I need?

    Determining the right system size requires a professional assessment. Our technicians calculate the appropriate capacity based on your home's square footage, insulation quality, and window placement—not just the size of your space.
  • How can I improve indoor air quality?

    You can enhance your home's air quality by replacing filters on schedule, installing air purifiers, keeping humidity levels between 30–50%, and ensuring adequate ventilation throughout your home.
  • Why is my AC freezing up?

    An air conditioner that's freezing typically suffers from low refrigerant, clogged filters, or restricted airflow preventing proper operation.
  • What is a heat pump?

    A heat pump is an energy-efficient system that transfers heat rather than generating it. During summer, it removes heat from your home, and in winter, it extracts heat from outside air and brings it indoors.
  • What are signs I need a new HVAC system?

    You should consider replacing your system if it's 10–15 years old or older, your energy bills are increasing without explanation, you're scheduling frequent repairs, or you're experiencing inconsistent temperatures throughout your home.
  • How often should I get maintenance?

    We recommend scheduling professional maintenance twice annually—one service visit for your air conditioning system and another for your furnace.
