Frequently Asked Questions About HVAC Companies

Find answers to common questions about HVAC services, finding contractors, and getting the best heating and cooling solutions for your needs.

What is an AFUE rating, and why is it important?

AFUE (Annual Fuel Utilization Efficiency) measures how effectively a furnace converts fuel to heat. Higher AFUE furnaces waste less fuel. The minimum AFUE for new furnaces is usually 80%, but modern furnaces can achieve AFUE ratings of 90-98%. Investing in a high-efficiency furnace can save money on heating costs over time.

How can I tell if my furnace filter needs changing?

Here are some signs your furnace filter needs changing (remember to change it every 1-3 months):
  • Reduced Airflow: Noticeably weaker airflow from your vents.
  • Dusty Vents: Dust accumulation around your vents.
  • Increased Dust: More dust than usual in your home.
  • Allergies or Respiratory Issues: Worsening allergy symptoms or respiratory problems.
  • Higher Energy Bills: Your furnace becomes less efficient.
  • Overheating: The system overheats due to restricted airflow.
Check your filter monthly and change it as needed to maintain good indoor air quality and HVAC system efficiency.

How can I improve my home's indoor air quality?

You can take these steps to improve your indoor air quality (IAQ):
  • Regular Air Filter Replacement: Change or clean your HVAC system’s air filters regularly (every 1-3 months).
  • Professional Air Duct Cleaning: Have your air ducts cleaned by professionals every few years to eliminate dust, mold, and other contaminants.
  • Improve Ventilation: Ensure adequate ventilation in your home to bring in fresh air and exhaust stale air. Use exhaust fans in kitchens and bathrooms.
  • Control Humidity Levels: Use a humidifier or dehumidifier to maintain optimal humidity levels and prevent mold growth.
  • Clean Regularly: Dust and vacuum frequently to minimize airborne particles.
  • Avoid Smoking Indoors: Smoking indoors significantly reduces IAQ.
  • Use Natural Cleaning Products: Opt for natural cleaning products that don’t release harmful VOCs (volatile organic compounds).
  • Monitor Indoor Air Quality: Consider using an indoor air quality monitor to track pollutant levels.
If you have persistent IAQ issues, consult with an HVAC professional or an indoor air quality specialist for further assessment and solutions.

What are the most common HVAC problems?

Common HVAC problems include:

  • AC not cooling: Refrigerant leaks, compressor issues, or thermostat problems.
  • Furnace not heating: Pilot light or ignition control issues, blower motor problems, or clogged filters.
  • Uneven temperatures: Ductwork leaks, inadequate insulation, or faulty thermostats.
  • Poor air quality: Dirty air filters, mold growth in ductwork, or inadequate ventilation.
  • Strange noises: Unusual sounds from the system can indicate a variety of problems with different components.
  • High energy bills: Inefficient systems, ductwork leaks, or improper thermostat settings.
If you're experiencing any of these issues, contact a qualified HVAC technician for diagnosis and repair.
