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.

How can I tell if my furnace filter needs changing?

You should change your furnace filter regularly, typically every 1-3 months, or more often if you have pets or allergies. Here are some signs your filter needs changing:
  • 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: A dirty filter restricts airflow, forcing your furnace to work harder.
  • 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.

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

AFUE (Annual Fuel Utilization Efficiency) measures how effectively a furnace converts fuel to heat. A higher AFUE rating means greater efficiency and lower energy bills. 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.

What type of HVAC system is best for my home?

The best HVAC system for your home depends on several factors, including your:
  • Climate: Heat pumps are generally more efficient in moderate climates, while furnaces are better for colder regions.
  • Budget: The upfront cost of different systems can vary significantly.
  • Energy Efficiency Goals: Higher-efficiency systems are usually more expensive upfront but result in lower energy bills over time.
  • Home Size and Layout: The square footage and layout of your home affect the system's capacity and ductwork requirements.
  • Existing Ductwork: If you have existing ductwork, you'll need a system compatible with it.
A qualified HVAC contractor can assess your needs and recommend the most suitable HVAC system for your property.
