What Proper Installation Gets You

When your AC installation is done right, you get consistent cooling in every room. No more hot spots upstairs or freezing cold downstairs while other areas stay warm.

You’ll see the difference in your energy bills too. A properly sized and installed system runs efficiently instead of constantly cycling on and off, which wastes energy and drives up costs.

Most importantly, you get reliability when you need it most. During those 90-degree July days when everyone’s AC is working overtime, yours keeps running because it was installed to handle Canton’s climate demands from day one.

Local Experience You Can Count On

We’ve been serving Canton and Norfolk County homeowners with professional HVAC services for years. We’re not the biggest company in Massachusetts, but we’re built for this area.

How We Handle Your Installation

First, we assess your home’s cooling needs and existing ductwork. This isn’t a quick walk-through—we measure rooms, check insulation, and examine your electrical setup to determine the right system size and type.

Next, we remove your old equipment and prepare the installation site. This includes any necessary electrical work, ductwork modifications, or structural adjustments to accommodate your new system.

The installation itself typically takes a full day. We connect all refrigerant lines, test the electrical connections, and run the system through multiple cycles to verify everything operates correctly. Before we leave, we walk you through the controls and answer any questions about your new AC system.

What's Included in Every Installation

Every air conditioning installation includes complete system testing and startup. We don’t just connect the equipment and leave—we verify that refrigerant levels are correct, airflow is balanced, and all safety controls function properly.

You also get a thorough explanation of your new system’s operation and maintenance requirements. Many Canton homeowners have never owned a modern, high-efficiency AC system, so we make sure you understand how to get the best performance and longevity from your investment.

All installations come with warranty coverage on both the equipment and our labor. Plus, as a Dempsey Energy customer, you’re eligible for our Dempsey Comfort Club membership, which provides priority service and maintenance benefits to keep your system running smoothly year after year.

Most residential air conditioning installations in Canton take one full day, typically 6-8 hours. However, older homes sometimes require additional work like electrical upgrades or ductwork modifications, which can extend the timeline to two days. We’ll give you an accurate timeframe after assessing your specific situation during the initial consultation. Factors that affect timing include the complexity of your ductwork, accessibility of the installation area, and whether any electrical panel upgrades are needed to handle the new system’s power requirements.
The right AC size depends on your home’s square footage, insulation quality, window placement, and ceiling height—not just the size of your old system. Many Canton homes have oversized or undersized units that were improperly selected years ago. We perform a proper load calculation that considers your home’s specific characteristics, including how much sun exposure you get and the age of your windows and insulation. An oversized system cycles on and off too frequently, while an undersized system runs constantly without adequately cooling your home.
Yes, we obtain all necessary permits for AC installation work in Canton and handle the inspection process with the local building department. Most air conditioning installations require an electrical permit, and some may need a mechanical permit depending on the scope of work. We’re familiar with Canton’s specific requirements and have established relationships with local inspectors, which helps promote a smooth permit and inspection process. The permit costs are typically included in our installation quote so there are no surprises.
Absolutely. Many older Canton homes were built before central air conditioning was common, so we regularly install ductwork as part of AC installation projects. We can run ducts through basements, attics, or crawl spaces depending on your home’s layout. In some cases, ductless mini-split systems might be a better option if running traditional ductwork is disruptive or expensive. During our consultation, we’ll evaluate your home’s structure and recommend the most practical and cost-effective approach for adding central air conditioning.
All our AC installations come with extensive warranty coverage on both the equipment and our installation work. If you experience any issues related to the installation, we’ll return to diagnose and resolve the problem at no charge. We also provide detailed information about the manufacturer’s equipment warranty, which typically covers parts for several years. As part of our commitment to customer service, Dempsey Comfort Club members receive priority scheduling for any service calls, verifying you get fast attention if any issues arise with your new system.
AC installation costs vary significantly based on the system size, efficiency rating, complexity of the installation, and any additional work needed like electrical upgrades or ductwork modifications. Rather than giving you a generic price range that might not apply to your situation, we provide detailed, written estimates after evaluating your specific needs. This approach assures you understand exactly what’s included and why certain costs are necessary. We’ll also explain different system options and efficiency levels so you can make an informed decision that fits your budget and cooling needs.
