The AC Installation Process We Follow
We understand that every home and customer in Greensburg has unique needs. That’s why our AC installation service is beyond a simple equipment swap. We provide a fully transparent, step-by-step approach so you know exactly what to expect.
1. Initial Consultation & Home Assessment
Our team begins by reviewing your home’s current cooling system, if any, and discussing your comfort goals and budget. We conduct a detailed inspection covering:
- Home size, layout, and insulation quality
- Existing duct system condition and design
- Current cooling equipment performance
- Electrical system capacity
- Any local regulations or HOA requirements impacting installation
This thorough evaluation allows us to tailor a solution specific to your home’s characteristics.
2. Precise System Sizing with Manual J Load Calculation
One of the most critical steps in AC installation is selecting the right system capacity. Oversized or undersized units lead to inefficiency and discomfort. We perform a Manual J load calculation, the industry-standard method, considering factors such as:
- Home square footage and room configuration
- Windows, sunlight exposure, and shading
- Occupancy and heat-generating appliances
- Local weather patterns and humidity typical to Greensburg
This calculation determines the exact cooling capacity your home requires, ensuring balanced comfort and energy efficiency.
3. Equipment Selection & Ductwork Evaluation
Based on the Manual J results and your preferences, we recommend air conditioning systems from leading manufacturers known for energy efficiency and reliability. Our technicians evaluate your existing ductwork to identify if modifications or sealing improvements are needed to maintain airflow balance and system performance.
In some cases, duct replacement or enhancements may be necessary to optimize air distribution, especially for older Greensburg homes or if significant equipment upsizing is involved.
4. Expert Professional Installation
Our certified HVAC technicians then handle the careful installation of the new AC unit. This includes:
- Proper placement of the outdoor condenser to allow adequate airflow and reduce noise
- Installation of the indoor evaporator coil or air handler in line with your furnace or duct system
- Connecting electrical wiring and controls securely
- Charging the system with the precise amount of refrigerant
- Sealing any ductwork penetrations to prevent air leaks
Every installation is performed following manufacturer specifications and local Greensburg codes to ensure safety and optimal operation.
5. Post-Installation Testing & System Commissioning
After installation, we rigorously test the system for correct pressures, airflow, temperature differential, and electrical safety. This commissioning phase guarantees your new air conditioner runs at peak performance from day one.
6. Homeowner Orientation & Warranty Coverage
We educate you on system operation, thermostat programming, and routine maintenance practices to preserve system health. Plus, we explain the manufacturer’s warranty details and our service commitments so you’ll have peace of mind with your new AC system.
