Frequently Asked Questions About HVAC Companies

Find answers to common questions about HVAC services, finding contractors, and getting the best heating and cooling solutions for your needs.

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.

How can I reduce my HVAC energy consumption?

You can reduce HVAC energy consumption and lower your bills by:
  • Regular Maintenance: Schedule annual HVAC maintenance to ensure your system is running at peak efficiency.
  • Programmable Thermostat: Use a programmable or smart thermostat to optimize temperature settings based on your schedule.
  • Seal Air Leaks: Caulk and weatherstrip windows and doors to prevent drafts.
  • Proper Insulation: Ensure adequate insulation in your attic, walls, and floors to prevent heat loss in winter and heat gain in summer.
  • Ventilation: Use fans strategically to circulate air and reduce reliance on AC.
  • Energy-Efficient Appliances: Choose energy-efficient appliances to reduce your overall energy load.
  • HVAC Zoning: Consider zoning your HVAC system to condition different areas of your home separately.

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.

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 not cool 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 AC repair specialist to fix the leak and add refrigerant.
