Frequently Asked Questions About HVAC Companies

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 refrigerant lines or evaporator coil.
• Increased Energy Bills: Your system has to work harder to cool, leading to higher energy consumption.
• Hissing or Bubbling Sounds: These sounds can indicate a refrigerant leak.

If you suspect low refrigerant, contact an HVAC technician to diagnose the issue and recharge the system.

How long does an HVAC system last?

The average lifespan of an HVAC system is typically 15-20 years. However, how long your system lasts can vary depending on usage, maintenance, and the system's quality. Regular maintenance can extend the life of your HVAC system significantly. If your HVAC system is over 15 years old, it's a good idea to start considering a replacement.

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 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.
