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 signs my air conditioner needs refrigerant?

Low refrigerant levels can cause various problems with your air conditioner:
  • Warm Air: The most noticeable sign is that the AC is blowing warm or lukewarm air.
  • Ice Buildup: Ice may form on the AC unit.
  • Increased Energy Bills: Your system has to work harder to cool, leading to higher energy consumption.
  • Hissing or Bubbling Sounds: These sounds can indicate a refrigerant leak.
If you suspect low refrigerant, contact an HVAC technician to fix the leak and add refrigerant.

How do I choose the right HVAC contractor?

Selecting a qualified HVAC contractor is essential for a smooth and hassle-free HVAC project. Here’s what to look for:
  • Experience: Choose a contractor with extensive experience in the HVAC industry, especially in the type of service you need.
  • Licensing and Insurance: Verify that the contractor is properly licensed and insured.
  • Certifications: Look for NATE (North American Technician Excellence) certification, which indicates a high level of technical competency.
  • Reputation: Check online reviews and ratings to assess the contractor's reputation and customer satisfaction levels.
  • References: Ask for references from past customers and contact them to inquire about their experience.
  • Estimates and Quotes: Get written estimates or quotes from multiple contractors to compare pricing and services.
  • Warranty Information: Ask about warranties on equipment and labor.
  • Communication: Effective communication is key. Choose a contractor who responds promptly and clearly answers your questions.

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.
