Frequently Asked Questions About HVAC Companies

How do I choose the right size AC unit for my home?

Choosing the right AC unit size is essential for efficient cooling. An undersized unit won’t cool your home adequately, while an oversized unit will cycle on and off frequently, wasting energy and leading to premature wear and tear. A qualified HVAC technician will calculate the appropriate size AC unit for your home based on factors like:

• Your home's square footage
• Your local climate
• Insulation levels
• Window efficiency
• Number of occupants

This calculation involves determining your home's cooling load, typically measured in BTUs (British Thermal Units). Don’t rely on estimates or guesswork; consult with an HVAC professional to ensure your new AC unit is properly sized for your specific needs.

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 fix the leak and add refrigerant.

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 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.
