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.

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 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. If your HVAC system is over 15 years old, it's a good idea to start considering a replacement.

What are the benefits of a programmable thermostat?

A programmable thermostat allows you to schedule temperature changes throughout the day, reducing energy usage when you are not at home. This can significantly reduce your energy costs and improve home comfort.

What regular maintenance should I do on my HVAC system?

You can perform some simple maintenance tasks yourself to keep your HVAC system running smoothly:
  • Change Air Filters: Change or clean your air filters every 1-3 months. Dirty air filters restrict airflow and decrease system efficiency.
  • Clear Debris: Keep the area around your outdoor unit clear of debris, leaves, and snow.
  • Check Thermostat Settings: Make sure your thermostat is set to the desired temperature and is functioning correctly.
For more complex maintenance, like cleaning coils or checking refrigerant levels, contact a qualified HVAC technician. Schedule annual or biannual maintenance with a reputable HVAC contractor.
