Split AC Unit Guide
By Travis Baugh
Welcome to Bryant's comprehensive guide on split AC units. If you are in search of an efficient cooling solution for your home, split AC units are an excellent choice. In this guide, we will cover the benefits of split AC units, how to select the right split unit air conditioner for your needs, and the importance of proper installation and maintenance. By the end of this article, you will understand why split air conditioners are an ideal cooling solution for your home. Let's dive in!
What Is Split System Air Conditioning?
A split system air conditioner is a type of cooling system that consists of two main components: an outdoor unit (condenser, such as an air conditioner or heat pump) and an indoor unit (gas furnace or fan coil). The outdoor unit is responsible for releasing the heat absorbed from inside the home, while the indoor unit cools the air and circulates it throughout the space.
How Split System Air Conditioning Works
A split system air conditioner operates by transferring heat from inside the home to the outside environment. This is done using the basic principles of thermodynamics and refrigeration. The outdoor unit houses the condenser and compressor, while the indoor unit contains the evaporator coil. The two units are connected by refrigerant lines, which carry the refrigerant between them.
Cooling Process
The indoor unit draws in warm air from the room and passes it over the evaporator coil. The refrigerant inside the coil absorbs the heat, causing the air to cool down. This cool air is then circulated back into the room.
Heat Transfer
Once the refrigerant absorbs the heat from the indoor air, it becomes a gas and is pumped into the outdoor unit. Here, the refrigerant gas passes through the compressor, which increases its pressure and temperature. It then moves through the condenser coil, where it cools and turns back into a liquid.
Repeat Cycle
This cycle of heat absorption and transfer continues, cooling the indoor space and releasing the absorbed heat outdoors. The process is efficient and maintains a steady, comfortable temperature.
Key Components of a Split System
A split system air conditioner consists of several key components that work together to ensure effective cooling:
- Condenser: Located outside of the home, the AC condenser is responsible for releasing the heat absorbed from inside the space. It houses the compressor and the condenser coil.
- Compressor: The compressor is the heart of the system. It pressurizes the refrigerant gas, which helps facilitate heat transfer from the indoor to the outdoor unit.
- Evaporator Coil: The evaporator coil is located inside the building, typically as part of an air handler or central unit. It absorbs heat from the air in the room, cooling it before it is circulated back into the space.
- Refrigerant: The refrigerant is a chemical fluid that absorbs heat at the evaporator coil and releases it at the condenser coil. It circulates between the two units, transferring heat in the process.
- Air Handler/Fan: The air handler is responsible for circulating the cooled air throughout the space. It can be integrated into the indoor unit or connected to ductwork, depending on the system design. Learn more about what is an air handler.
Five Benefits of Split AC Systems
Split system air conditioning offers several benefits that make it a popular choice for cooling homes. Here are some key advantages:
1. Even Cooling Throughout the Home
Split AC systems provides consistent cooling across all rooms in the house, ensuring that every space is comfortable. Through the use of ducts and vents, cool air is evenly distributed, preventing hot spots and ensuring a uniform temperature throughout the home.
2. Improved Indoor Air Quality
Split air conditioning systems often come with built-in air filters that help remove dust, allergens, and other pollutants from the air, improving indoor air quality. Regular filter replacement and maintenance can help reduce the presence of airborne particles, benefiting those with allergies, asthma, or other respiratory issues.
3. Energy Efficiency
Modern central air conditioners are designed to be energy-efficient, with many models featuring high SEER2 (Seasonal Energy Efficiency Ratio) ratings. Energy-efficient units consume less electricity while providing effective cooling, leading to lower cooling bills and a reduced carbon footprint.
4. Quiet Operation
Unlike window or portable air conditioners, which can be noisy, central air conditioning systems operate quietly. The noisy components, such as the compressor and condenser, are located outside, while the indoor unit runs with minimal sound, contributing to a more peaceful indoor environment.
5. Convenient and Easy to Control
With central air conditioning, homeowners can control the temperature of the entire home using a thermostat, making it easy to maintain a comfortable indoor climate. Programmable and smart thermostats offer further convenience, allowing for temperature adjustments based on time of day and occupancy, enhancing comfort and energy savings from the convenience of a smart home app. Learn more about the best smart thermostats for your home.
Choosing the Right Split AC Unit
By considering all of these factors, you'll be better equipped to choose the right split air conditioning system for your home and needs.
Home Size and Layout
The size of your home will determine the cooling capacity you need. A larger home requires a split HVAC system with a higher tonnage (cooling capacity) to maintain comfortable temperatures. Homes with good insulation or open floor plans may require less cooling power, while homes with poor insulation or complex layouts might need a more powerful system or multiple zones for efficient cooling.
Cooling Capacity (BTUs/Tons)
Central AC units are rated in tons (1 ton = 12,000 BTUs per hour). The appropriate size for your home depends on factors like room dimensions, insulation quality, and local climate. Oversized or undersized systems can lead to inefficiency, higher energy costs, or inadequate cooling. Your local Bryant dealer can help you find the right air conditioner size for your home.
Energy Efficiency
Look for systems with a high SEER2 rating. A higher SEER2 indicates better energy efficiency, which can lower electricity bills. ENERGY STAR certified units are designed to meet higher energy efficiency standards, which can save money in the long run and reduce environmental impact.
Cost
The initial cost of the unit and AC installation can vary significantly based on size, brand, and features. A higher-efficiency system may have a higher upfront cost but offer savings over time.
Noise Levels
Different units have different noise levels. If quiet operation is important to you, look for systems that are specifically designed to operate quietly. Noise levels are measured in decibels (dB), with quieter models typically operating around 50-60 dB.
Split HVAC System Installation
Installation of a split system requires careful planning to ensure the units are properly placed for optimal airflow and efficiency. The indoor unit is typically installed in a central location, such as a basement or attic, and the outdoor unit placed in a well-ventilated area. Proper sealing of ductwork and insulation are essential to maximize energy efficiency and comfort. Professional installation is highly recommended to ensure the system operates effectively and complies with local codes. Learn more about AC installation.
Split AC Unit Maintenance
Regular maintenance of a split HVAC system is crucial to ensure its longevity and efficiency. This includes tasks such as regularly replacing air filter and scheduling annual professional maintenance for tasks such as checking and cleaning the evaporator and condenser coils, and inspecting ductwork for leaks. Scheduling annual professional maintenance can help identify potential issues early, improve energy efficiency, and prolong the life of the system. Learn more about AC maintenance.
