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.

What is an AFUE rating, and why is it important?

AFUE (Annual Fuel Utilization Efficiency) measures how effectively a furnace converts fuel to heat. A higher AFUE rating means greater efficiency and lower energy bills. The minimum AFUE for new furnaces is usually 80%, but high-efficiency furnaces can achieve AFUE ratings of 90-98%. Investing in a high-efficiency furnace can save money on heating costs over time.

What are the signs my air conditioner needs refrigerant?

Low refrigerant levels can cause various problems with your air conditioner:
  • Warm Air: The most noticeable sign is that the AC is blowing warm or lukewarm air.
  • Ice Buildup: Ice may form on the AC unit.
  • Increased Energy Bills: Your system has to work harder to cool, leading to higher energy consumption.
  • Hissing or Bubbling Sounds: These sounds may suggest a refrigerant leak.
If you suspect low refrigerant, contact an HVAC technician to diagnose the issue and recharge the system.

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: Ensure there are no obstructions near the vents inside your home.
  • 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.
