According to Angi, installing a new AC unit can cost up to $8,000(based on 2023 data). But installation doesn’t only include connecting and setting up a unit. There are several steps and tasks homeowners often aren’t aware of. This article will explain the process a trained HVAC technician will follow when providing AC installation service.
An AC installer will first inspect your home to identify your needs. Are you replacing an existing unit or relocating your HVAC system? Many newer air conditioners are larger in dimensional size, so the current location of your AC may be unsuitable. Manufacturer guidelines, state laws, and local regulations may dictate equipment placement, clearance, and distance from utility meters.
Plus, the installer will consider your climate and the typical levels of heat and humidity. They’ll also perform an energy audit to look for poor insulation, drafty windows, and other factors that can reduce efficiency. Recommendations on improvements often target ways to maximize an AC’s energy efficiency over time.
The size (capacity) of an HVAC system must be just right. A technician will determine the square footage of your home and consider other factors to identify the cooling power you need. Many people oversize their air conditioners, lowering efficiency and increasing wear and tear. While sizing an AC unit requires extra time, it can pay off in improved comfort, moisture removal, energy efficiency, and fewer repairs.
A reputable contractor will explain options that can provide more efficient cooling. If your AC is well-maintained, it can last 15 to 20 years. During that time, you can save significantly if the system is efficient. Air conditioner efficiencies are rated using the following:
During an AC installation service call is a good time to evaluate ductwork for issues that decrease efficiency. Some considerations include whether the duct system is compatible with or large enough for the new unit. An inspector will also determine if your ductwork needs to be sealed or repaired. If there’s significant dirt and dust buildup, air ducts will be cleaned as well.
The installation crew should call or text their expected arrival time. You’ll speak to the lead installer about the project, the equipment to be installed, and other details. Good communication avoids misunderstandings and costly mistakes. In preparation for your new system, the installers will turn off the electricity and gas supply to your existing HVAC equipment and add protection to floors and furniture. All the tools and equipment they’ll use will be set up.
The refrigerant will be safely recovered and discarded with special machinery. A technician who removes AC refrigerant must be EPA certified to do so. Next, electrical wiring is disconnected from the unit, and then the disconnect box and electric power conduit are replaced. The old condenser unit and indoor evaporator coil, air handler, and copper refrigerant line are carefully removed to make way for new equipment. If necessary, modifications to the plenum will be made.
The pad the outdoor unit sits on is replaced and leveled. The ground below it may need to be leveled too, either by laying a gravel base or pouring a concrete pad. Composite pads are often used as concrete is prone to cracking and shifting and not as resistant to machine vibrations. Thorough preparation is necessary because, after installation, air conditioners can’t be moved or lifted without causing serious damage.
The installation procedure depends on the exact type of air conditioner. The general process during AC installation service is as follows:
If installing a mini-split system, ductwork installation or modification will be skipped. The installation crew will drill one hole in an exterior wall to connect a conduit between the outdoor and indoor units.
