Frequently Asked Questions About HVAC Companies

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

How often should I have my HVAC system serviced?

Regular HVAC maintenance is essential for optimal performance, energy efficiency, and extending the lifespan of your system. It's generally recommended to have your system serviced once in the spring and once in the fall. Regular maintenance typically includes cleaning, inspections, and tune-ups of key components.

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.

How long does an HVAC system last?

The average lifespan of an HVAC system is about 15-20 years. However, the actual lifespan can vary depending on usage, maintenance, and the system's quality. Regular maintenance can extend the life of your HVAC system significantly. An older system is likely to be less efficient and more prone to repairs.
