Frequently Asked Questions About HVAC Companies

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

What are the most common HVAC problems?

Common HVAC problems include:

  • AC not cooling: Refrigerant leaks, compressor issues, or thermostat problems.
  • Furnace not heating: Pilot light or ignition control issues, blower motor problems, or clogged filters.
  • Uneven temperatures: Ductwork leaks, inadequate insulation, or faulty thermostats.
  • Poor air quality: Dirty air filters, mold growth in ductwork, or inadequate ventilation.
  • Strange noises: Unusual sounds from the system can indicate a variety of problems with different components.
  • High energy bills: Inefficient systems, ductwork leaks, or improper thermostat settings.
If you're experiencing any of these issues, contact a qualified HVAC technician for diagnosis and repair.

How do I choose the right size AC unit for my home?

Choosing the right AC unit size is essential for efficient cooling. An undersized unit won’t cool your home adequately, while an oversized unit will cycle on and off frequently, wasting energy and leading to premature wear and tear. A qualified HVAC technician will calculate the appropriate size AC unit for your home based on factors like:
  • Your home's square footage
  • Your local climate
  • Insulation levels
  • Window efficiency
  • Number of occupants
This calculation involves determining your home's cooling load, typically measured in BTUs (British Thermal Units). Don’t rely on estimates or guesswork; consult with an HVAC professional to ensure your new AC unit is properly sized for your specific needs.

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.

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.
