Frequently Asked Questions About HVAC Companies

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. Proper maintenance can help your system last longer. An older system is likely to be less efficient and more prone to repairs.

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: 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 keep your system running efficiently.

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 are the signs that I need a new HVAC system?

Several signs indicate it might be time for a new HVAC system:

• Frequent Repairs: If your system requires repairs often, it may be more cost-effective to replace it.
• Age of System: HVAC systems typically last 15-20 years. If your system is nearing or beyond that age, it's likely less efficient and more prone to breakdowns.
• Increased Energy Bills: A significant rise in energy bills might mean your system is losing efficiency and needs replacement.
• Uneven Temperatures: If some rooms are too hot or too cold, it could be a sign of ductwork problems or an undersized/aging system.
• Poor Indoor Air Quality: If you're experiencing allergies, dust, or other indoor air quality issues, a new HVAC system with better filtration could help.
• Strange Noises or Smells: Unusual noises or foul odors emanating from your HVAC system could signal a problem that requires a system replacement.

If you're unsure whether you need a new system, contact a trusted HVAC technician for an assessment.
