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 different types of HVAC systems?

Several types of HVAC systems are available for residential and commercial buildings:
  • Split Systems: The most common type, consisting of an outdoor unit (condenser/compressor) and an indoor unit (air handler/furnace).
  • Heat Pumps: Provide both heating and cooling by transferring heat between indoor and outdoor air.
  • Ductless Mini-Splits: Ideal for homes without existing ductwork or for adding heating and cooling to specific zones.
  • Packaged Units: A single unit that contains all the system's components.
  • Geothermal Heat Pumps: Use the earth's stable temperature to provide highly efficient heating and cooling.
An HVAC professional can help determine the best type of system for your needs and budget.

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.
