Types of Air Conditioners We Install

Every home is different, and so is every cooling solution. Our comfort advisors will assess your home’s size, layout, insulation, and existing ductwork to recommend the right system for you.

Central Air Conditioners

The most common choice for Ottawa homes with existing ductwork. A central AC system pairs with your furnace to deliver consistent, whole-home cooling. We carry high-efficiency models with SEER2 ratings that reduce energy costs while keeping every room comfortable.

Ductless Mini-Split Systems

No ductwork? No problem. Ductless mini-splits are ideal for additions, older homes, or rooms that never quite reach the right temperature. One outdoor unit can connect to multiple indoor heads, giving you room-by-room control without the expense of installing new ducts.

Heat Pumps

A heat pump does double duty — cooling your home in summer and heating it in winter. Modern cold-climate heat pumps are engineered for Canadian winters and can qualify for Ontario’s Home Renovation Savings Program rebates. Ask us if a heat pump makes sense for your home.

Signs You Need a New Air Conditioner

Not sure whether to repair or replace? Here are signs it may be time for a new installation:

  • Your AC is 15 years old or more
  • Repair bills are adding up — multiple service calls in one season
  • Your energy bills are rising despite normal usage
  • Certain rooms stay hot no matter how long the AC runs
  • The system makes unusual noises or cycles on and off frequently
  • Humidity levels inside feel uncomfortable even with AC running

Frequently Asked Questions

AC installation costs in Ottawa typically range from $3,500 to $7,500 or more depending on the type of system, the size of your home, and whether new ductwork is needed. Contact us for a free in-home quote — we'll give you an exact price before any work begins.
Most central air conditioner installations are completed in one day — typically 4 to 8 hours. Ductless mini-split installations can be faster. We will give you a time estimate before we start.
In most cases, yes — installing a new central air conditioning system in Ottawa requires a permit. Capital City handles all required permits and inspections on your behalf, so you don't have to worry about the paperwork.
Sizing depends on your home's square footage, insulation, ceiling height, window placement, and sun exposure. An undersized unit won't cool effectively; an oversized unit will cycle on and off too quickly. Our technicians perform a proper load calculation to find the right fit.
Certain high-efficiency systems — particularly qualifying heat pumps — may be eligible for rebates through Ontario's Home Renovation Savings Program. We will review current rebate availability and eligibility during your free consultation.
