Central AC + Mini-Split Installation
Get a clear quote for central air or ductless mini-split installation from Denoco. We size for comfort, humidity control, airflow, and long-term reliability across Kingston, Amherstview, Bath, Napanee, Gananoque, and surrounding Eastern Ontario communities.
If you already have good ductwork, a central AC is usually the cleanest fit. If you do not have ducts, or you have one stubborn room that never gets cool, a ductless mini-split (single or multi-zone) is often the better answer. We walk you through both based on your actual house.
If your unit is more than 12-15 years old, uses old R-22 refrigerant, is noisy, or your bills keep climbing, replacement usually pays off in the first few summers. We will give you an honest "repair vs replace" call instead of pushing the bigger ticket.
Oversized AC short-cycles and leaves the house clammy. Undersized AC runs forever and never catches up on the worst days. We size based on heat-gain reality, not square-footage rules of thumb, so the system actually controls humidity and stays quiet.
Mini-splits shine for additions, second-storey bedrooms, finished basements, garage workshops, and older homes that were never built for ductwork. Multi-zone systems run several indoor heads off one outdoor unit, so you cool only the rooms that need it.

Rule of thumb: if the repair cost is over 30-50% of a new system, the unit is older than 12 years, or it uses old R-22 refrigerant, replacement usually wins on bills and reliability. We give you a straight read after a quick look.
Central AC uses existing ductwork to cool the whole house. Ductless mini-splits mount on a wall (or ceiling) and cool only the rooms you put them in. Mini-splits are perfect for homes without ducts or for tough rooms; central is cleaner if you already have ducts.
It depends on equipment, electrical service, existing ductwork, and removal. We give you a written quote after a quick site visit — no vague numbers over the phone.
Single-zone installs are usually the lowest-cost path; multi-zone systems cost more but cool more rooms off one outdoor unit. We will give you options after seeing the home.
Yes — that is one of the cases mini-splits are best at. We size the head and the outdoor unit for the actual room load.
Most central AC installs run one to two days. Single-zone mini-splits are often a one-day job. Multi-zone systems vary with the number of heads and how they are routed.
Usually yes. We check airflow, return capacity, and the condenser location before confirming so the system actually delivers the comfort you are paying for.
Yes — we offer financing options and walk you through what works for your situation.
Manufacturer warranties on the equipment, plus our installation warranty. We confirm the exact terms in writing on every quote.
