The process of replacing a central air conditioner involves assessing your current system, picking a new unit, preparing for installation, and having professionals handle the air conditioner installation. You'll start by checking if your old AC is truly at the end of its life expectancy.
Next, you'll pick a new air conditioning unit that fits your home and budget. Then, you'll clear the area for workers and ensure your home is ready.

Key Takeaways
You need to check your current system and pick a new unit that’s right for your home.
Getting your house ready before the HVAC installation team arrives is key for a smooth process.
A new, more efficient cooling system can lead to better comfort and lower energy costs.
Assessing Your Current System
Before replacing your central AC system, it's crucial to evaluate your existing setup. This step helps you make informed decisions about the new HVAC unit's capacity and efficiency standards.
Evaluating the Existing Unit
Take a close look at your current air conditioner. How old is it? Most units last 10-15 years, and if yours is nearing this age, it might be time for an air conditioner replacement.
Check for signs of wear and tear. Are there strange noises or hot air from the vents? Does it struggle to cool your home? These could be red flags.
Look at your energy bills. Have they gone up lately? An inefficient AC can lead to higher costs, signaling it's time to upgrade.
Consider how often you've needed repairs. Frequent fixes may indicate it’s time for unit replacement.
Determining Capacity and Efficiency
Your new AC should fit your home's cooling needs. Measure your living space to determine the right size unit. Look at the SEER rating, too. Higher numbers mean better efficiency, helping to increase efficiency and reduce costs over time.
Think about your home's insulation and sun exposure, as well as any changes since the current system was installed, such as new windows or added rooms.
Energy Star-certified units are a good option to help operate efficiently and save money long-term.
Choosing a New Central Air Conditioner
Picking the right air conditioning system is crucial for your comfort and energy efficiency.
Types of Air Conditioners
When you're looking for a new central air conditioner, you have a few options. Split systems are common. They have an outdoor unit and an indoor unit connected by pipes. These work well for homes that already have ducts.
Packaged units are another choice. Everything is in one big outdoor box. These can be good if you don't have much space inside.
Heat pumps are a third option. They can cool your home in summer and heat it in winter. This can save you money if you live somewhere with mild winters.
Features and Innovations
New air conditioners have cool features that can make your life easier. Look for ones with high SEER ratings. SEER stands for Seasonal Energy Efficiency Ratio. The higher the number, the less energy it uses.
Some units have two-stage compressors. These can run at low power on mild days to save energy. Others have variable-speed motors that adjust to your needs.
Smart thermostats are a great add-on. They let you control your AC from your phone. Some can even learn your habits and adjust on their own.
Moisture removal is another key feature. Look for units that can keep your home's humidity just right. This makes you feel more comfy without turning the temp way down.
Pre-Installation Preparations
Getting ready to replace your central air conditioner involves important steps. You'll need to find the right professional and make sure you have the proper paperwork in order.
Hiring a Professional HVAC Contractor
To start, you'll want to find a qualified HVAC contractor. Look for licensed professionals who have experience with air conditioner installations. Ask friends and family for recommendations, or check online reviews.
Get at least three quotes from different contractors. Make sure each quote includes the same services and equipment for a fair comparison.
Ask potential contractors about their experience, certifications, and insurance. A good contractor will do a home assessment to determine the right size unit for your space.
Don't forget to ask about warranties on both labor and equipment. A reputable contractor should offer both.
Obtaining Necessary Permits
Before any work begins, you'll need to get the right permits. Your HVAC contractor can usually help with this process.
Check with your local building department to find out what permits are needed. Most areas require permits for replacing central air conditioning systems.
The permit process helps ensure that the installation meets local safety and building codes. It may involve inspections before, during, and after the installation.
Getting permits might seem like a hassle, but it's important. It protects you and ensures the job is done right. Skipping this step could lead to fines or problems when selling your home.
Remember, the cost of permits is usually separate from the contractor's quote. Ask about this upfront to avoid surprises.
The Installation Process
Replacing your central AC involves several key steps. A professional HVAC contractor will carefully remove the old unit, install the new HVAC system, and inspect your ductwork.
Removal of the Old Unit
The first step is taking out your old air conditioner. The team will turn off power to the unit at your home's electrical panel. They'll disconnect the old system from electrical wiring and refrigerant lines.
Next, they'll remove the outdoor condenser unit. This often involves unscrewing it from its pad. They'll also take out the indoor evaporator coil from your furnace or air handler.
The crew will properly dispose of the old refrigerant following EPA rules. They may need to use special tools to remove the old unit, especially if it's in a tight spot.
Installation of the New Unit
Now it's time to put in your new air conditioner. The team will place the outdoor unit on a level concrete pad. They'll connect it to your home's electrical system and refrigerant lines.
Inside, they'll install the new evaporator coil in your furnace or air handler. This part helps cool the air that flows through your home.
The installers will add the right amount of refrigerant to your system. They'll also set up a new thermostat if you're getting one.
Ductwork Inspection and Repair
Your ductwork is key to your AC's performance. The team will check for leaks, damage, or poor insulation. They might use special tools to test airflow and find any problems.
If they find issues, they'll seal leaks with mastic or metal tape. They may add insulation to ducts in unconditioned spaces like attics. This helps your system work better and saves energy.
Sometimes, ductwork might need to be changed to fit the new system. This could involve resizing or moving some ducts for better airflow.
Post-Installation Checklist
Once the new AC unit is installed, testing the system is essential. Make sure the cooling system is working correctly, with no leaks or malfunctions.
Testing the System
Once your new AC is in place, it's time to check if it works correctly. Turn on the system and listen for any odd noises. Feel the air coming from the vents - it should be cool and flowing strongly.
Check the thermostat to make sure it's reading the right temperature. Set it to different levels and see if the AC responds as it should.
Look for any leaks around the unit or ductwork. Water or refrigerant leaks can cause big problems if not fixed quickly.
Ask your installer to show you how to change the air filter. This is a task you'll need to do regularly.
Proper Maintenance Tips
To keep your new AC running smoothly, you'll need to take care of it. Change or clean the air filter every 1-3 months. This helps your system run more efficiently.
Keep the outdoor unit clear of leaves, grass, and debris. Trim any plants growing near it to ensure good airflow.
Schedule yearly professional maintenance with 338Aircon. A technician can catch small issues before they become big problems.
Clean your air vents regularly to keep dust from building up. This improves air quality and helps your AC work better.
Check your thermostat settings often. Make sure they're set for comfort and energy savings.
