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 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 an inefficient HVAC 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 the need for a new HVAC system.
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?

You should change your furnace filter regularly, typically every 1-3 months, or more often if you have pets or allergies. Here are some signs your filter needs changing:
  • 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 maintain good indoor air quality and HVAC system efficiency.

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.

What is the difference between an AC unit and a heat pump?

While both air conditioners and heat pumps provide cooling, they differ in how they generate heat. An AC unit cools your home by extracting heat and transferring it outside. It uses a separate furnace or heating system for heating in colder months. A heat pump, however, can both cool and heat. In cooling mode, it functions like an AC, extracting heat from indoor air and releasing it outdoors. In heating mode, it reverses this process, extracting heat from the outside air (even in cold temperatures) and transferring it inside. This makes heat pumps more energy-efficient for heating than traditional electric resistance heating, especially in mild to moderately cold climates.

  • Increased Energy Bills: A significant rise in energy bills could indicate 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.
