Types Of Central Air Conditioners

When summer heat waves hit, a central air conditioner becomes a home essential. Understanding the different types of central air systems helps in choosing the perfect cool companion for your home. Let’s dive into the two main categories: split systems and packaged units.

Split Systems Versus Packaged Units

Split systems are the most common central air conditioners. They have two main components: an outdoor unit, called a condenser, and an indoor unit, usually connected to a furnace or air handler. The indoor and outdoor units work together to cool your home efficiently.

Packaged units, on the other hand, combine the condenser, compressor, and evaporator into a single outdoor unit. Ideal for homes with limited indoor space, they often sit on the roof or on a concrete slab near the house.

  • Split System Pros: Quieter operation, more energy-efficient, easier to maintain.
  • Split System Cons: Requires more indoor space, higher upfront installation cost.
  • Packaged Unit Pros: Space-saving, cheaper to install, all components protected in one casing.
  • Packaged Unit Cons: Generally noisier, less efficient, and more exposed to weather elements.

Energy Efficiency Ratings

Energy efficiency is crucial for keeping cooling costs down. Central air conditioners have efficiency ratings known as SEER (Seasonal Energy Efficiency Ratio). The higher the SEER rating, the more efficient the system.

Rating Efficiency
13-15 SEER Standard Efficiency
16-20 SEER High Efficiency
21+ SEER Super Efficiency

Select a unit with a SEER rating that fits your budget and climate needs. Remember, investing in a higher SEER rating can lead to lower energy bills in the long run.

Planning For Installation

Before installing a central air conditioner, proper planning is crucial. This step ensures your new system operates efficiently. The planning phase includes assessing your home’s layout and choosing the right size unit. Let’s explore these key factors.
