A reliable central air conditioning system is an excellent investment for home comfort. Whether upgrading an old unit or installing a new one, the proper AC ensures a cool, energy-efficient home. With so many options, choosing the best system can feel overwhelming. At Green City Heating and Air Conditioning, we make it easy. From selecting the perfect SEER-rated unit to expert central air install in Fall City, WA, we’re here to help. Let’s explore the types of central air units, tips for efficiency, and common AC myths.

Types of Central Air Conditioning Units
Choosing the right central air unit starts with understanding the available types. Each system has advantages, depending on your home's needs and existing setup. Here are a few of them:
- Split-System Air Conditioners: This popular air conditioning system features an outdoor condenser unit paired with an indoor evaporator coil, linked by refrigerant lines. Designed for homes with existing ductwork, it efficiently distributes cool air throughout the entire space, delivering consistent and reliable comfort. Its widespread use is a testament to its effectiveness in maintaining ideal indoor temperatures.
- Packaged Air Conditioners: A single outdoor unit that houses all the components of an air conditioning system, including the compressor, condenser, and evaporator. These are an excellent option for homes with limited indoor space, as they free up room and are typically installed on the ground or roof.
- Heat Pump Systems: These adaptable systems offer both heating and cooling by moving heat instead of producing it, resulting in exceptional energy efficiency. By extracting heat from the air or ground, they provide year-round comfort while reducing energy consumption and utility costs. They are sustainable for year-round comfort and especially effective in moderate climates.
- Ductless Mini-Split Systems: Ideal for homes without existing ductwork, these systems feature an outdoor unit connected to multiple indoor air handlers, allowing for customized, zoned cooling in different areas of the home. They allow for customized temperature control in different parts of the home and are perfect for additions, renovations, or older homes without existing ducts.
Each type has pros and cons; the right choice depends on your home’s size, insulation, and cooling needs. Our Green City Heating and Air Conditioning team can help you determine the best fit for your home.
How to Choose the Right SEER Rating for Central Air
The SEER (Seasonal Energy Efficiency Ratio) rating measures an air conditioner's efficiency by calculating how effectively it transforms electricity into cooling output over a typical season. A higher SEER means better efficiency, but how do you know which rating is correct?
- Consider Your Climate: In Fall City, WA, where summers are warm but not extreme, choosing a SEER rating of 16-18 often provides an outstanding balance between energy efficiency and upfront cost. This range ensures your air conditioning system runs efficiently without overspending on unnecessary features for the local climate.
- Evaluate Your Energy Savings: Although higher SEER units (18+) come with a greater upfront investment, they offer significant long-term energy savings by reducing electricity consumption and lowering monthly utility bills. Over a few years, these units could save you hundreds—or even thousands—on your energy bills, making them a worthwhile investment for those looking to reduce long-term costs.
- Check for Rebates & Incentives: Many high-SEER models save energy and qualify for utility rebates or government incentives, which can help offset the initial cost. Research local energy programs to see if you can use these savings opportunities.
- Match It to Your Home’s Size: Bigger isn’t always better regarding SEER ratings. Installing a high-SEER unit in a small home won’t necessarily result in more significant energy savings and can even lead to inefficiencies. Ensure your system is sized correctly so your home performs well without unnecessary costs.
Choosing the right SEER rating involves balancing efficiency, budget, and home size. Our HVAC experts can help you determine the best SEER rating for your home’s needs.
How Central Air Improves Indoor Air Quality
Beyond cooling your home, a central air system is vital in improving indoor air quality. Keeping your AC unit well-maintained can greatly improve indoor air quality, making a noticeable difference for those with allergies, asthma, or excessive dust accumulation in their home.
- Air Filtration: Central air systems are equipped with filters that capture dust, pollen, pet dander, and other airborne pollutants, enhancing indoor air quality. For households with allergy sufferers or those looking for superior filtration, upgrading to a HEPA or high-MERV filter can trap finer particles, effectively minimizing allergens and airborne irritants for a cleaner, healthier home environment.
- Humidity Control: Too much humidity fosters the growth of mold, mildew, and bacteria, creating potential health risks and causing damage to your home’s structure and belongings. Central AC systems regulate indoor humidity levels, keeping your home comfortable and protected from moisture-related problems.
- Ventilation & Air Circulation: Stagnant air indoors can result in reduced air quality and discomfort. Central AC systems ensure continuous airflow throughout your home, minimizing stale air, odors, and airborne pollutants. This consistent circulation creates a healthier, more pleasant living space.
- UV Light Purification Options: Many modern central AC systems offer UV light purification technology, which uses ultraviolet light to kill bacteria, viruses, and microorganisms as air passes through. This extra purification enhances air quality, which is ideal for health-conscious homeowners.
To improve air quality and cooling efficiency, ask us about filter upgrades and air purification systems during your central air installation.
Tips for Making Your Central Air More Energy Efficient
Cooling your home shouldn’t mean breaking the bank on energy bills. With a few thoughtful adjustments, you can keep your home comfortable while improving efficiency.
- Upgrade to a Programmable or Smart Thermostat: These advanced devices allow you to set customized temperature schedules, ensuring your home stays comfortable while reducing unnecessary energy use when you're away. Many smart thermostats can also learn your preferences over time and adjust automatically for greater efficiency.
- Change Air Filters Regularly: Dirty air filters block airflow, forcing your HVAC system to work harder to maintain the desired temperature, which increases energy consumption and utility bills. To keep your system running smoothly and efficiently, change the filters every 1-3 months or more often if you have pets or allergies.
- Seal and Insulate Ducts: Air leaks in ductwork can cause up to 30% of conditioned air to escape, resulting in higher energy costs and uneven temperatures across your home, making your HVAC system work harder than necessary. Sealing and insulating your ductwork ensures more conditioned air reaches its destination, improving comfort and efficiency.
- Use Ceiling Fans: Ceiling fans enhance air circulation, ensuring cool air is evenly distributed throughout the room. By using fans alongside your AC, you can raise the thermostat a few degrees without compromising comfort, leading to noticeable energy savings. Just remember to switch the fan direction to counterclockwise in summer for optimal cooling.
- Schedule Regular Maintenance: Scheduling yearly professional maintenance allows technicians to detect and address small problems early, preventing them from developing into expensive repairs. Routine maintenance keeps your HVAC system operating at peak efficiency, minimizes energy waste, and extends the lifespan of your equipment for long-term reliability and savings. It's a simple way to keep your home comfortable while saving money in the long run.
With minor changes, you can significantly improve the efficiency of your central air system, saving money and reducing your carbon footprint.
