Is your old AC unit costing you a fortune in energy bills and frequent repairs? It might be time for an Air Conditioner Change (Replacement). MDTECH Services specializes in professional AC system replacement and installation, helping homeowners across Orange County and Los Angeles County, CA, upgrade to high-efficiency, reliable cooling.
Choosing to change your air conditioner is a major decision—we make the process seamless, affordable, and fully tailored to your home’s specific comfort needs.
Why Consider an Air Conditioner Change?
Replacing an outdated or failing unit offers immediate and long-term benefits that far outweigh the cost of endless repairs.
1. Immediate & Long-Term Cost Savings
Modern AC units use significantly less energy than models 10–15 years old.
Lower Utility Bills: New systems have higher SEER2 ratings, meaning they convert less electricity into cooling power. You could save 20% to 40% on monthly energy costs.
Reduced Repair Costs: Eliminate the stress and expense of recurring breakdowns on an aging system.
2. Enhanced Comfort & Air Quality
Newer models provide more consistent, quiet, and superior cooling comfort:
Variable Speed Technology: Modern units (like heat pumps and variable-speed systems) run constantly at lower speeds, eliminating temperature swings and hot/cold spots.
Improved Filtration: New AC systems integrate with advanced air quality features to filter out dust, allergens, and pollutants common in Southern California air.
3. The R-22 Refrigerant Phase-Out
If your unit is older, it likely uses R-22 refrigerant (Freon), which has been phased out due to environmental regulations. If your R-22 unit leaks, the gas is scarce and extremely expensive to recharge, making replacement the most financially sound choice.
5-Step MDTECH Air Conditioner Change Process
Our professional installation ensures your new system is sized correctly and installed perfectly to maximize its lifespan and efficiency.
| Step | Action by MDTECH Experts | Importance |
| 1. Load Calculation | Perform a precise Manual J load calculation to determine the exact size (tonnage) your home requires. | Prevents oversizing or undersizing, which causes system strain and inefficiency. |
| 2. System Removal | Safely and legally recover and dispose of the old system and any remaining refrigerant (like R-22). | Ensures environmental compliance and site safety. |
| 3. Pad & Line Set Prep | Replace the condenser pad and flush or replace the refrigerant line set to ensure optimal performance of the new unit. | Vital for system longevity and leak prevention. |
| 4. Installation & Connection | Install the new indoor coil and outdoor condenser, braze the line set, evacuate the lines with a vacuum pump, and connect all electrical components. | Guarantees a leak-free, correctly wired, and high-performing system. |
| 5. Testing & Warranty | Test the system for correct airflow, temperature output, and pressure. We register all manufacturer warranties and walk you through system operation. | Confirms maximum efficiency and validates your investment protection. |
