Here's How Your Installation Actually Happens

First, we assess your home’s cooling needs and existing ductwork. This isn’t a quick glance – it’s a thorough evaluation of square footage, insulation, window placement, and airflow patterns to determine the right system size.

Next comes the installation itself. We handle electrical connections, refrigerant lines, and ductwork modifications if needed. Everything gets tested multiple times before we consider the job complete.

Finally, we walk you through your new system’s operation and maintenance requirements. You get warranty information, service recommendations, and direct contact details for any future needs. No guessing games about who to call if something goes wrong.

What's Included in Your Installation

Your AC installation covers everything needed for proper operation. That includes electrical work, refrigerant line installation, condensate drainage, and thermostat setup. We don’t hand you a list of extras after starting the job.

Green Harbor homes often need ductwork adjustments for optimal airflow. If your existing ducts won’t handle your new system efficiently, we address that during installation rather than leaving you with poor performance.

You also get startup testing and system commissioning. This means checking refrigerant levels, airflow measurements, and electrical connections to ensure everything operates within manufacturer specifications. It’s the difference between an AC that works and one that works properly.

Most air conditioning installations take 6-8 hours for a standard replacement, though this can vary based on your home’s specific requirements. If ductwork modifications are needed or electrical upgrades are required, the installation might extend to a full day or require a second visit. Factors like accessibility to your current system, the type of unit being installed, and any unexpected issues can affect timing. We’ll give you a realistic timeframe during the initial assessment so you can plan accordingly.
AC sizing depends on multiple factors beyond just square footage, including ceiling height, insulation quality, window placement, and local climate conditions. An oversized unit will short cycle and waste energy, while an undersized system will run constantly without achieving comfortable temperatures. The proper approach involves calculating your home’s actual cooling load using Manual J calculations, which account for all these variables. This ensures you get a system that cools efficiently without unnecessary energy consumption.
Yes, there are several options for homes without existing ductwork. Ductless mini-split systems are popular because they don’t require extensive ductwork installation and offer zone-by-zone temperature control. Alternatively, new ductwork can be installed, though this is more involved and costly. The best choice depends on your home’s layout, your cooling needs, and your budget. During the assessment, we’ll explain which options work best for your specific situation and provide realistic expectations for each approach.
Your installation comes with warranty coverage on both the equipment and the installation work itself. Equipment warranties typically cover parts and sometimes labor for several years, while installation warranties cover any issues related to the actual installation process. If problems arise, you have direct contact information for service calls rather than going through a call center. As part of our customer management system, we track all installations and can quickly access your system details when you need service.
Most AC installations require permits, especially if electrical work is involved or if you’re installing a new system rather than replacing an existing one. The permit process ensures the installation meets local building codes and safety standards. We typically handle permit applications as part of our service, since we know local requirements and have established relationships with permit offices. This protects you from potential issues if you ever sell your home or need insurance claims related to your HVAC system.
Replacing your AC before complete failure gives you more options and better timing control. You can schedule installation during moderate weather rather than during a heat wave when everyone needs emergency service. You also have time to research systems, compare options, and potentially take advantage of seasonal promotions or rebates. Signs it’s time to consider replacement include frequent repairs, rising energy bills, uneven cooling, or a system over 10-12 years old. Planning ahead usually results in better system selection and lower overall costs.
