Thinking about installing a new air conditioning system in your Glendora or Oakland, CA home? Whether you’re replacing an outdated unit or setting up a cooling system for the very first time, the process can be overwhelming without proper guidance. From choosing the right type of AC system to navigating the installation process and understanding ongoing maintenance, there are several important steps involved.
In areas like Glendora and Oakland, where temperatures can rise quickly during warmer months, having a reliable and energy-efficient air conditioning system isn’t just a luxury—it’s a necessity. That’s why we’ve created this comprehensive guide to help homeowners make informed decisions every step of the way. Whether you’re concerned about system size, energy efficiency, or what to expect on installation day, this article will equip you with the knowledge you need for a smooth and successful AC installation experience.

System Selection
Choosing the right AC system is the first and most critical step. Here’s what you need to consider:
1. Assessing Your Home’s Cooling Needs
Every home is unique, and your cooling requirements depend on factors like:
- Square footage: Larger homes need more powerful systems.
- Insulation quality: Well-insulated homes retain cool air better.
- Sun exposure: Homes with large windows or direct sunlight may require higher cooling capacity.
A professional HVAC technician can perform a load calculation to determine the ideal system size for your home.
2. Types of AC Systems
There are several types of AC systems to choose from:
- Central Air Conditioning: Best for whole-house cooling, this system uses ductwork to distribute cool air.
- Ductless Mini-Split Systems: Ideal for homes without ducts, these systems offer zoned cooling and energy efficiency.
- Window Units: Affordable and easy to install, but suitable only for single rooms.
- Portable Air Conditioners: Flexible and movable, but less efficient for larger spaces.
3. Energy Efficiency and SEER Ratings
Energy efficiency is a top priority for homeowners. The Seasonal Energy Efficiency Ratio (SEER) measures how efficiently an AC system operates. Higher SEER ratings mean better energy efficiency, which translates to lower utility bills. Look for systems with a SEER rating of at least 14 for optimal performance.
4. Choosing the Right Size
An improperly sized AC system can lead to inefficiency and higher costs. An undersized unit will struggle to cool your home, while an oversized unit will cycle on and off too frequently, wasting energy. A professional load calculation ensures you select the right size for your home.
The Installation Process
Once you’ve selected the right system, the installation process begins. Here’s what to expect:
1. Initial Consultation and Assessment
A licensed HVAC technician will visit your home to evaluate your cooling needs, inspect your existing system (if applicable), and recommend the best options. This is also the time to discuss your budget and any specific requirements.
2. Preparing Your Home for Installation
Before installation day, take these steps to prepare:
- Clear the installation area of furniture, decorations, or obstacles.
- Secure pets and children to ensure their safety and avoid disruptions.
- Confirm that your contractor has obtained all necessary permits.
3. The Installation Day
On the day of installation, the HVAC team will:
- Remove the old unit (if applicable) and dispose of it properly.
- Install the new indoor and outdoor units, along with ductwork (if needed) and a thermostat.
- Connect the system to your home’s electrical supply.
- Test the system to ensure it’s functioning correctly and efficiently.
4. Post-Installation Inspection
After installation, the technician will conduct a thorough inspection to verify proper airflow, refrigerant levels, and overall system performance. They’ll also explain how to operate your new system and answer any questions.

Post-Installation Maintenance Tips
Proper maintenance is essential to keep your AC system running efficiently and extend its lifespan. Here are some tips:
1. Regular Cleaning and Filter Replacement
- Clean the outdoor unit regularly to remove debris and ensure proper airflow.
- Replace air filters every 1-3 months to maintain efficiency and indoor air quality.
2. Seasonal Maintenance
- Spring Tune-Up: Schedule a professional inspection before the cooling season to check refrigerant levels, clean components, and ensure optimal performance.
- Fall Maintenance: Cover the outdoor unit in the fall to protect it from debris and winter weather.
3. Professional Inspections
Annual inspections by a licensed HVAC technician can identify potential issues early, saving you from costly repairs down the line.
4. Energy Efficiency Tips
- Use a programmable thermostat to adjust temperatures when you’re away.
- Seal leaks in windows and doors to prevent cool air from escaping.
- Use ceiling fans to distribute cool air more evenly, allowing you to set your thermostat higher.
