An air conditioning unit is one of the most vital components of home comfort, especially in the intense Texas heat. But even the most reliable systems won’t last forever. Over time, wear and tear from years of use, lack of proper AC maintenance, and outdated technology can reduce performance and increase your energy bills. At Shellaby A/C & Refrigeration, we often get asked when it’s time to replace a unit and what the AC replacement process actually involves. This guide is designed to walk you through the steps so you can make informed, stress-free decisions when the time comes.
Replacing an air conditioner is more than just swapping out one system for another. It involves a careful assessment of your current cooling system, your home’s HVAC needs, and choosing the right equipment for maximum energy efficiency. If you’re dealing with common AC problems such as uneven cooling, frequent breakdowns, or unusually high energy costs, it may be time to consider a full replacement rather than another short-term AC repair.
When is AC Replacement Necessary?
Before diving into the replacement process, it’s important to understand whether your unit really needs to be replaced. Many homeowners struggle to decide between repair and replacement. While professional air conditioner repair can solve a wide range of issues, there are times when replacement is simply the smarter investment. If your system is over 10–15 years old, requires frequent repairs, or is using outdated refrigerant like R-22, it may be time to upgrade.
At Shellaby A/C & Refrigeration, our expert HVAC repair technicians can help assess whether AC maintenance or a targeted repair will extend the system’s life—or if replacement is the most cost-effective solution. We always aim to provide honest guidance based on your system’s condition, energy efficiency, and long-term costs.
Step 1: System Evaluation and Load Calculation
The first step in the AC replacement process is a thorough evaluation of your existing system and your home’s specific cooling needs. This includes calculating your home’s cooling load—a critical process that ensures your new unit is properly sized. Oversized units can short-cycle and waste energy, while undersized systems may struggle to keep your home comfortable.
Shellaby A/C & Refrigeration’s HVAC professionals use industry-standard Manual J calculations to determine the ideal cooling capacity for your space. We consider factors like square footage, insulation quality, window placement, ductwork condition, and more to ensure optimal system performance.
Step 2: Selecting the Right System
Today’s air conditioning systems are far more advanced than those from a decade ago. They offer better energy efficiency, quieter operation, and smart features like programmable thermostats and zoning capabilities. Once we determine the correct size, we’ll guide you through system options based on your budget, preferences, and energy-saving goals.
As part of our Air Conditioning Replacement services, Shellaby A/C & Refrigeration offers high-efficiency units from trusted brands with SEER (Seasonal Energy Efficiency Ratio) ratings that meet or exceed federal standards. Choosing a high-efficiency unit may involve a higher upfront cost, but the savings on energy bills and the potential for rebates make it a smart long-term investment.
Step 3: Removing the Old Unit
Once the new system is selected, we carefully remove the existing air conditioning unit. This includes disconnecting electrical wiring, refrigerant lines, and ductwork connections. Our HVAC repair technicians ensure that all removal is done safely and in accordance with environmental standards, particularly when dealing with refrigerant disposal.
Improper removal can damage components or release harmful substances into the environment, which is why trusting licensed professionals like Shellaby A/C & Refrigeration is essential. We handle every step with care to protect both your home and the environment.
Step 4: Installing the New Unit
After the old system is out of the way, we begin the installation of your new AC. This is the most crucial stage of the AC replacement process. Every detail matters—from leveling the outdoor unit for proper drainage to ensuring airtight duct connections and correct thermostat integration.
Our team also checks and upgrades electrical components as needed and verifies the integrity of the refrigerant lines. Each step is executed with precision to guarantee that your new system operates at peak performance from day one. Once installed, the system is charged with the correct refrigerant and pressure-tested to ensure it’s ready for action.
Step 5: Post-Installation Testing and System Calibration
Installation doesn’t end once the unit is turned on. We conduct thorough post-installation testing to check for proper airflow, refrigerant levels, thermostat accuracy, and overall system performance. We also walk you through the system’s operation and help you understand how to use programmable settings to save energy and enhance comfort.
At Shellaby A/C & Refrigeration, we believe in getting it right the first time. That’s why we stay until every component is tested and you’re fully confident in your new system.
Step 6: Ongoing Maintenance and Warranty Support
A new AC unit is a significant investment—protecting it with regular AC maintenance is key to long-term performance. We offer customized maintenance plans that include seasonal tune-ups, filter replacements, and performance checks. These proactive measures reduce the risk of common AC problems and keep your system running like new.
Additionally, we help you register your manufacturer’s warranty and provide information about what’s covered. Many manufacturers require proof of professional air conditioner repair and maintenance to honor warranty claims, so partnering with Shellaby A/C & Refrigeration ensures you’re fully protected.
