Types of Conditioners

Central air conditioners come in two main types: split-system units and packaged units. This is a crucial consideration when deciding which type to install in your home.
Split-system central air conditioners have an outdoor unit containing the heat exchanger, fan, and compressor, and an indoor unit with the heat exchanger and blower. This setup is often preferred because it allows for more flexibility in terms of installation and maintenance.
A heat pump can be a great alternative to a split-system air conditioner if you already have a furnace but no air conditioner. Heat pumps can provide both heating and cooling efficiently.
Packaged central air conditioners, on the other hand, have all the components - heat exchanger, compressor, fan, and blower - located in one cabinet. This cabinet is typically placed on a roof or concrete slab next to the house's foundation.
Here are the key differences between split-system and packaged central air conditioners:
By considering these factors, you can make an informed decision about which type of central air conditioner is best for your home.
Choosing or Upgrading Your Conditioner

Central air conditioners are more efficient than room air conditioners, consuming less energy and producing fewer emissions. They're also quieter, more convenient, and out of the way.
To save energy and money, buy an energy-efficient model and reduce your central air conditioner's energy use. In an average-sized home, air conditioning can consume more than 2,000 kilowatt-hours of electricity per year.
A central air conditioner can be a significant investment, but it's worth considering the long-term benefits. For example, a new energy-efficient model can pay for itself over time through reduced energy bills.
When choosing or upgrading your conditioner, consider the following factors:
- Energy efficiency: Look for models with high SEER ratings (up to 22 or more) and high AFUE ratings (up to 95 or more).
- Size: Ensure the unit is correctly sized for your home, using an Air Conditioning Contractors of America (ACCA) Manual J Load Calculation.
- Features: Consider models with advanced features like smart thermostats, humidity control, and air purification.
- Warranty: Check the manufacturer's warranty and customer support.
Pumps and Energy Efficiency
Heat pumps are a great option for whole house HVAC systems, especially in moderate climates. They provide both heating and cooling and can be more efficient than traditional air conditioners.
One key benefit of heat pumps is their ability to switch between heating and cooling functions depending on the temperature. This makes them ideal for a variety of climates.
Proper sizing is crucial for an efficient heat pump system. An oversized unit won't adequately remove humidity, while an undersized unit won't cool effectively on the hottest days.
A high SEER (Seasonal Energy Efficiency Ratio) rating is also important. Newer systems can have SEER ratings as high as 26.
To maximize energy efficiency, look for the ENERGY STAR and EnergyGuide labels. ENERGY STAR certified units are about 15% more efficient than standard models.
Variable capacity systems are another option to consider. These units run often but usually at very efficient low speeds, offering minimal sound and enhanced dehumidification.
Here are some key features to look for in an energy-efficient heat pump system:
- High SEER rating (up to 26)
- ENERGY STAR certification (15% more efficient)
- Variable capacity system (minimal sound and enhanced dehumidification)
Inverter technology is also worth exploring. It allows the compressor to change its frequency to match the demand for heating or cooling.
Cooling System Options and Process
Central cooling systems are a crucial part of a whole house HVAC system, and there are several options to choose from.
A split-system air conditioner is a common type of central cooling, consisting of an indoor and outdoor unit that work together to distribute cool air through a system of ducts in your home.
The indoor unit holds a fan and evaporator coil, while the outdoor unit holds a fan, condenser, and condenser coil, all connected by copper tubes.
There are also packaged air conditioners, which are a single unit that sits outside the house, taking air from the home, cooling it, and then supplying it back through ductwork.
Central cooling kicks off when a thermostat senses that the temperature in your home needs to be changed, and the process involves several steps to cool your home.
Here's a simplified overview of the central cooling process:

Cooling Process
The cooling process is a crucial part of keeping your home comfortable, especially during hot summer months.
Central cooling systems work by taking heat and humidity from your home and releasing it outside, dropping the temperature inside. This process involves multiple parts working together to achieve the desired temperature.
Here's a step-by-step breakdown of the central cooling process:
- A fan from the indoor portion of your AC moves room temperature hot air out of your home.
- This air is filtered, so dust, lint and debris are taken out.
- The filtered, hot air is blown over the evaporator coil, a portion of your air conditioner that gets filled with liquid refrigerant.
- The newly cooled air is pumped back into your home via ducts.
- The heat that was recently absorbed needs a place to go, so the heated, gaseous refrigerant passes through a copper tube into the outdoor portion of your air conditioner.
- The refrigerant is put into the compressor, which pressurizes the gas and sends it to the condenser coil.
- The condenser coil releases the heat that used to be in your home from the refrigerant, turning it back into a liquid.
- The process starts again.
For optimal efficiency, it's recommended to set your central air system's fan to "auto" mode and use circulating fans in individual rooms for additional air circulation.
Cooling System Options
Central cooling systems come in three main types: split-system air conditioners, heat pumps, and packaged air conditioners.
A split-system air conditioner has an outdoor and indoor unit that work together to distribute cool air through ducts in your home.
The two units are connected by copper tubes and ductwork throughout the house.
A heat pump can reverse the flow of refrigerant to heat the home, making it a more versatile option.
Packaged air conditioners, on the other hand, have the entire unit sitting outside the house, with no equipment inside.
They take air from your house through return ductwork, cool it, and then supply it back to the house through supply ductwork.
A split-system AC only cools, while a heat pump can both cool and heat the home.
The five main parts of a central air conditioning system include a thermostat, outdoor unit, indoor unit, copper tubes, and ductwork.
