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 high-efficiency furnaces can achieve AFUE ratings of 90-98%. Investing in a high-efficiency furnace can save money on heating costs over time.

What are the different types of HVAC systems?

Several types of HVAC systems are available for residential and commercial buildings:

Split Systems: The most common type, consisting of an outdoor unit (condenser/compressor) and an indoor unit (air handler/furnace).
Heat Pumps: Provide both heating and cooling by transferring heat between indoor and outdoor air.
Ductless Mini-Splits: Ideal for homes without existing ductwork or for adding heating and cooling to specific zones.
Packaged Units: A single unit that contains all the system's components.
Geothermal Heat Pumps: Use the earth's stable temperature to provide highly efficient heating and cooling.

An HVAC professional can help determine the best type of system for your needs and budget.

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 do I find a good HVAC company near me?

Finding a reputable HVAC company requires research. Consider these tips:

Check Online Reviews: Look for HVAC companies with positive reviews and high ratings on platforms like Google, Yelp, and others.
Ask for Referrals: Reach out to friends, family, neighbors, or colleagues for recommendations.
Verify Licensing and Insurance: Ensure the company is properly licensed and insured to operate in your area.
Look for Certifications: Check for certifications from reputable organizations like NATE (North American Technician Excellence).
Compare Quotes: Get quotes from multiple HVAC companies to compare pricing and services.
Use a Directory like HVACCompaniesHub: Simplify your search by using our directory of pre-screened and qualified HVAC professionals.

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 high-efficiency furnaces can achieve AFUE ratings of 90-98%. Investing in a high-efficiency furnace can save money on heating costs over time.
