AC Replacement Process

Here's How We Handle Installation

First, we assess your home’s cooling needs and existing ductwork to determine the right system size and type. This isn’t guesswork – we calculate the actual load requirements based on your home’s square footage, insulation, windows, and layout.

Next, we remove your old equipment safely and prepare the installation area. Our technicians protect your floors and belongings during the work. We install the new system according to manufacturer specifications, connecting refrigerant lines, electrical components, and ductwork properly.

Finally, we test everything thoroughly before we leave. We check refrigerant levels, airflow, electrical connections, and thermostat operation. You’ll know exactly how to operate your new system and what to expect for ongoing maintenance. The installation area gets cleaned up completely.

Most residential air conditioning installations take 6-8 hours for a complete system replacement. This includes removing the old equipment, installing the new indoor and outdoor units, connecting refrigerant lines, and testing everything thoroughly. Larger homes or complex installations may take longer. We’ll give you a realistic timeframe upfront so you can plan accordingly. Factors like accessibility, ductwork modifications, and electrical upgrades can extend the installation time, but we work efficiently to minimize disruption to your daily routine.
The right AC size depends on your home’s square footage, insulation levels, window types, ceiling height, and local climate conditions. We perform a proper load calculation to determine the exact cooling capacity you need. An oversized system will cycle on and off frequently, wasting energy and failing to remove humidity properly. An undersized system will run constantly and struggle to keep you comfortable. Our technicians measure and calculate these factors during the estimate process to ensure you get a system that’s properly matched to your home’s specific cooling requirements.
Yes, we handle all necessary permits and coordinate required inspections for your air conditioning installation. This ensures your installation meets local building codes and manufacturer requirements. Proper permitting protects you if you ever sell your home and ensures the work is done to professional standards. We know Duxbury’s local requirements and work with municipal inspectors regularly. The permit process is included in our installation service, so you don’t need to worry about navigating the paperwork or scheduling inspections yourself.
Absolutely. We install both central air systems with new ductwork and ductless mini-split systems that don’t require ducts at all. For homes without existing ductwork, ductless systems are often the most efficient and cost-effective option. These systems use individual indoor units connected to an outdoor compressor, allowing you to control temperatures in different zones independently. If you prefer central air, we can design and install a complete duct system, though this involves more extensive work. We’ll evaluate your home and discuss both options so you can choose what works best for your situation and budget.
Your new air conditioning system comes with manufacturer warranty coverage on parts and our workmanship guarantee on the installation. If you experience any issues, we’ll diagnose and resolve them promptly. Our Dempsey Comfort Club members get priority scheduling for service calls. Most installation-related issues surface within the first few weeks, and we stand behind our work completely. We also provide ongoing maintenance services to prevent problems and keep your system running efficiently. Our goal is to ensure you’re completely satisfied with your AC installation and the performance of your new cooling system.
AC installation costs vary based on system type, home size, existing infrastructure, and specific equipment selected. Central air systems, ductless mini-splits, and heat pumps all have different price ranges. Factors like ductwork modifications, electrical upgrades, and accessibility affect the total investment. We provide detailed estimates that break down equipment and installation costs clearly. Rather than giving you a generic price range, we prefer to assess your specific situation and provide an accurate quote based on your home’s actual requirements. This ensures you get realistic pricing without surprises.
