We Replaced a 21-Year-Old AC Before Lunch | 4-Ton ACiQ Heat Pump Install

Can a complete 4-ton central HVAC system really be replaced before lunch? We get it done so we can go to the bar for lunch! In this full, uncut installation, Mikey Pipes and the Pipe Doctor team remove a 21-year-old Carrier central air-conditioning system and replace it with a high-performance ACiQ Extreme+ communicating inverter heat pump system in Woodmere, New York. We started at approximately 7:30 AM—and had the new system heating and cooling before noon. The old Carrier equipment still looked surprisingly clean from the outside, but its indoor evaporator coil had developed a refrigerant leak. At 21 years old, investing in a major repair no longer made financial sense. The homeowners chose to upgrade to a modern inverter-driven heat pump capable of providing efficient cooling and heating throughout the year. This video shows the entire process with nothing hidden: ✅ Pumping down the old Carrier system ✅ Removing the overgrown outdoor condenser ✅ Installing a heavy-duty wall-mounted heat pump bracket ✅ Keeping the outdoor unit above the Long Island snow line ✅ Reusing and professionally reforming the existing line set ✅ Creating and torqueing new flare connections ✅ Installing the Mikey Pipes SPD-01 surge and voltage protection panel ✅ Wiring the ACiQ S1/S2 communicating system ✅ Nitrogen pressure testing ✅ Pulling a deep vacuum measured in microns ✅ Charging the system with R-454B refrigerant ✅ Installing the ACiQ communicating thermostat ✅ Measuring the system’s actual amperage ✅ Testing its whisper-quiet operation At the end of the installation, this 48,000-BTU inverter heat pump was operating at approximately 13 amps while cooling the home. That is the advantage of modern inverter technology. Instead of repeatedly starting and stopping at full capacity, the system can automatically adjust its output based on the actual heating or cooling demand inside the home. This can provide more consistent temperatures, quieter operation, improved humidity control and greater energy efficiency. You’ll also see why evacuation is one of the most important parts of any HVAC installation. Air and moisture left inside a refrigeration system can contribute to acid formation, contaminated oil and premature compressor failure. Anyone can bolt equipment onto a house—the work you cannot see is what often determines how long that equipment will last. And then there’s the Fieldpiece core removal tool… After another frustrating leak during the vacuum and commissioning process, Mikey finally had enough. Watch until the end to see exactly what happened and why the tool received the full “Fisher-Price Fieldpiece” treatment. NEED HVAC SERVICE ON LONG ISLAND?
