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 long does an HVAC system last?

The average lifespan of an HVAC system is typically 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. If your HVAC system is over 15 years old, it's a good idea to start considering a replacement.

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.

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 a ductless mini-split system?

A ductless mini-split system is a type of HVAC system that doesn't require ductwork. It consists of an outdoor unit (compressor/condenser) and one or more indoor units (air handlers) connected by refrigerant lines and electrical wiring. Each indoor unit cools or heats a specific zone or room, providing individual temperature control. Ductless mini-splits are more energy-efficient than traditional ducted systems and are a good option for homes without existing ductwork.
