Detailed Breakdown: The Full Heat Pump Installation Process
1. Pre-Installation Evaluation and System Sizing
A proper installation starts with an expert home evaluation. Technicians perform a Manual J load calculation to determine the exact size and capacity your heat pump needs. This assessment factors in your home’s square footage, insulation, windows, and local climate.
Installing the wrong-sized system is one of the most common mistakes—and one that Allison Air Conditioning & Heating, Inc. avoids by customizing solutions for every property.
2. Removal of Existing HVAC Equipment
If you’re replacing a furnace, AC, or old heat pump, the old unit will be carefully disconnected and removed. Technicians safely handle refrigerants and other materials, disposing of them according to environmental regulations. Removing the old system also allows for any necessary upgrades to ductwork, wiring, or mounting surfaces.
This step is handled efficiently to minimize downtime in your home’s comfort.
3. Installation of the New Heat Pump System
This is where the new equipment gets placed and connected. It includes mounting the outdoor compressor unit, installing the indoor air handler, running refrigerant lines, and connecting the electrical components. If needed, updates are made to your thermostat to ensure full system compatibility.
Every detail is checked—airflow, duct connections, drainage, and energy supply—before proceeding to the next step.
4. System Testing and Performance Calibration
Once installed, your technician will start up the heat pump to verify everything is functioning as expected. This includes refrigerant charge testing, thermostat communication, airflow measurement, and temperature accuracy. Safety checks are also performed to ensure reliable long-term operation.
The system is fine-tuned to balance efficiency and comfort for both heating and cooling modes.
5. Customer Walkthrough and Final Sign-Off
Before the job is complete, the technician will walk you through how to use and maintain your new heat pump.
