Frequently Asked Questions About HVAC Companies

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 tell if my furnace filter needs changing?

You should change your furnace filter regularly, typically every 1-3 months, or more often if you have pets or allergies. Here are some signs your filter needs changing:

• Reduced Airflow: Noticeably weaker airflow from your vents.
• Dusty Vents: Dust accumulation around your vents.
• Increased Dust: More dust than usual in your home.
• Allergies or Respiratory Issues: Worsening allergy symptoms or respiratory problems.
• Higher Energy Bills: Your furnace becomes less efficient.
• Overheating: The system overheats due to restricted airflow.

Check your filter monthly and change it as needed to maintain good indoor air quality and HVAC system efficiency.

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 is the difference between an AC unit and a heat pump?

While both air conditioners and heat pumps provide cooling, they differ in how they generate heat. An AC unit cools your home by extracting heat and transferring it outside. It uses a separate furnace or heating system for heating in colder months. A heat pump, however, can both cool and heat. In cooling mode, it functions like an AC, extracting heat from indoor air and releasing it outdoors. In heating mode, it reverses this process, extracting heat from the outside air (even in cold temperatures) and transferring it inside. This makes heat pumps more energy-efficient for heating than traditional electric resistance heating, especially in mild to moderately cold climates.
