For homes without ductwork — or anyone looking for highly energy-efficient cooling — ductless mini-splits are an excellent solution. These systems offer targeted cooling for individual rooms or zones, often using 30-40% less energy than central AC.
Why Ductless Mini-Splits Make Sense:
Want to know if a mini-split is right for your home? Schedule a free consultation with a Home Comfort Advisor — we’ll walk you through the rebate options and sizing. Learn more about ductless mini-splits.

Zoned air conditioning systems let you customize the temperature in different areas of your home — ensuring every room stays comfortable while optimizing energy efficiency. It’s a smart upgrade for larger homes, multi-story properties or any home with rooms that cool unevenly.
Why Choose Zoned Cooling?
Whether you’re installing a new zoned AC system or upgrading your current setup, your Dempsey Energy Home Comfort Advisor will design a solution that fits your home. Schedule a free consultation or call 774-719-0298.
It depends on the age and condition of your system. As a general rule, if your AC is over 10 years old AND the repair would cost more than 50% of a new system, replacement usually makes more sense long-term. Newer systems are also significantly more energy-efficient, which means lower utility bills. Our Home Comfort Advisors can give you an honest assessment during a free in-home consultation.
AC installation costs vary depending on your home’s size, the type of system you choose (central air, ductless mini-split, or heat pump), and whether ductwork modifications are needed. We provide free in-home estimates so you know the exact cost before any work begins. Financing is available and many systems qualify for Mass Save rebates.
AC sizing isn’t as simple as matching square footage — your home’s insulation, window count, ceiling height, and orientation all matter. We perform a Manual J load calculation during every installation estimate to determine the precise BTU capacity your home needs. An undersized AC will run constantly without cooling effectively; an oversized one cycles on and off too quickly and wastes energy. Our technicians get the sizing right the first time.
Annual maintenance is the industry recommendation — ideally in the spring before cooling season begins. Regular tune-ups extend system lifespan, maintain energy efficiency, and catch small issues before they become expensive repairs. Many manufacturers require documented annual service to keep warranties valid. Ask us about our maintenance plan for priority scheduling and discounted service.
Mini-splits are an excellent choice for homes without existing ductwork, additions, garages, finished basements, or rooms that don’t cool evenly with central AC. They’re highly energy-efficient (often 30-40% more efficient than central AC) and let you cool only the spaces you’re using. Learn more about our mini-split installations.
Most new AC systems come with a manufacturer’s warranty covering parts. On select new HVAC installations, Dempsey Energy also includes a 10-year labor warranty at no additional cost — meaning if a covered part fails during that window, you’re not paying for the repair labor either. Your Home Comfort Advisor will explain which warranty options apply to the system you’re considering during your consultation.
