Frequently Asked Questions About HVAC Companies

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.

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 regular maintenance should I do on my HVAC system?

You can perform some simple maintenance tasks on your own 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.

What are the benefits of a programmable thermostat?

A programmable thermostat allows you to set different temperatures throughout the day, reducing energy usage when you are not at home. Programmable thermostats can make managing your HVAC system easier and more efficient.
