Our AC Installation Process

Straightforward Installation, Professional Results Every Time

We start with a thorough assessment of your home to determine the right system size and placement. This isn’t guesswork—we calculate your cooling load based on square footage, insulation, windows, and how your family actually uses your space.

Once we’ve selected the right equipment, we handle all permits and scheduling. Our installation team arrives on time, protects your home with floor coverings and equipment pads, and installs your system according to manufacturer specifications and local codes.

After installation, we test every component, walk you through your new system’s operation, and make sure you’re completely satisfied before we consider the job complete. You’ll also receive information about our Dempsey Comfort Club, which provides ongoing maintenance to keep your investment running efficiently for years to come.

Complete AC Installation and Replacement

Everything You Need for Reliable Home Cooling

Your AC installation includes proper equipment sizing, professional installation of both indoor and outdoor units, refrigerant line installation, electrical connections, and ductwork modifications if needed. We handle all permits, inspections, and manufacturer warranty registration.

For homes without existing ductwork, we design and install complete duct systems that supply even cooling throughout your home. If you’re replacing an existing system, we’ll remove your old equipment responsibly and ensure your new system integrates seamlessly with your current setup.

Every installation comes with thorough testing, system startup, and a complete walkthrough so you understand how to operate and maintain your new air conditioning system. We also provide ongoing support through our Dempsey Comfort Club membership program.

How long does AC installation take in a typical Foxborough home?

Most air conditioning installations take one to two days, depending on your home’s setup and whether we’re working with existing ductwork. If you’re adding central air to a home that never had it, we might need an additional day for ductwork installation. We’ll give you a clear timeline during our initial assessment so you can plan accordingly. Weather can sometimes affect outdoor unit installation, but we’ll keep you informed if any delays come up.

What size AC unit do I need for my Norfolk County home?

The right size depends on much more than just square footage. We calculate your home’s cooling load based on insulation levels, window placement, ceiling height, and how many people typically occupy the space. Many Norfolk County homes need anywhere from 2 to 5 tons of cooling capacity, but oversizing is just as problematic as undersizing. An oversized unit cycles on and off too frequently, wasting energy and failing to remove humidity properly. We take precise measurements and calculations to get it right the first time.

Do I need permits for AC installation in Foxborough?

Yes, AC installation in Foxborough requires permits for both electrical and mechanical work. We handle all permit applications and scheduling inspections as part of our service. This protects you by verifying the work meets local building codes and doesn’t affect your home’s insurance or resale value. Some homeowners try to skip permits to save money, but their actions can create serious problems down the road. We include all necessary permits in our installation process so you don’t have to worry about compliance issues.

Can you install AC in older homes without existing ductwork?

Absolutely. Many Norfolk County homes were built before central air conditioning was standard, and we regularly install complete duct systems along with new AC units. We design ductwork routes that minimize impact on your home’s structure and appearance, often using basement, attic, or closet spaces for main trunk lines. The process takes longer than a simple equipment replacement, but the result is whole-home comfort that wasn’t possible before. We’ll walk through your home and explain exactly how we’d route the ductwork before starting any work.

What happens if my new AC system has problems after installation?

All equipment comes with manufacturer warranties that we help you navigate if issues arise. Beyond that, our Dempsey Comfort Club provides ongoing maintenance and priority service for system problems. We stand behind our installation work and will return to address any issues related to our workmanship. Most problems with new systems are actually minor adjustments or settings that we can resolve quickly. Our goal is your complete satisfaction, and we maintain relationships with our customers long after installation is complete.

How much energy will a new AC system save compared to my old one?

Energy savings depend on your current system’s age and condition, but most homeowners see a 20-40% reduction in cooling costs with a new, properly sized system. If you’re replacing a system that’s over 10 years old, the efficiency improvements can be dramatic. Modern systems also provide better humidity control, which means you’ll feel comfortable at higher thermostat settings. We can review your current energy bills and give you realistic expectations for savings based on the specific equipment we’re recommending for your home.
