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 type of HVAC system is best for my home?

The best HVAC system for your home is unique to your situation, including your:
  • Climate: Heat pumps are generally more efficient in moderate climates, while furnaces are better for colder regions.
  • Budget: The upfront cost of different systems can vary significantly.
  • Energy Efficiency Goals: Higher-efficiency systems are usually more expensive upfront but result in lower energy bills over time.
  • Home Size and Layout: The square footage and layout of your home affect the system's capacity and ductwork requirements.
  • Existing Ductwork: If you have existing ductwork, you'll need a system compatible with it.
A qualified HVAC contractor can assess your needs and recommend the most suitable HVAC system for your property.
