How Does an HVAC Contractor Add Central Air Conditioning?

More than half of existing homes have central air conditioning or some combination of central and window units. So if you’re considering adding central air to an existing home, you have a lot of company, according to data. 

It’s not even close in terms of new home construction: More than 90% of newly constructed homes nationwide now come equipped with central air. Fortunately, an HVAC contractor in Edmonton can handle every type of AC unit.

In this post, learn why you should add central air conditioning to your home. 

Easier Breathing

Another benefit of installing central air conditioning is improved indoor air quality. The air conditioner in Edmonton serves as a whole-house filtration system in addition to cooling every room. Every day, several times, the blower in a central air system circulates the whole volume of indoor air. 

The system filter continuously removes airborne particulates like dust, allergens, and other irritants as household air moves through the ductwork to preserve the quality of the air in your entire home.

The improvements in air quality that may be achieved by installing central air conditioning and utilizing high-quality air filters are incomparable to those achieved by a furnace blower that runs only half the year or a window unit’s smaller air filter.

Ductwork Is Important

The good news is that you might already own it. The bad news is that you might hesitate to install central air conditioning if you don’t. It can be frightening to imagine walls being knocked down to install new ducts and a protracted, disruptive building job. Contrary to popular belief, the truth is completely different:

As was already noted, if you have a forced-air furnace, you may already have installed appropriate ductwork for cooling. Many times, existing ducts can be used to link a central A/C system without the need for additions. 

A competent HVAC contractor can perform the calculations required to determine whether upgrading to a more powerful but frequently more energy-efficient blower is advised or whether the current furnace blower can handle the airflow needed to cool the property.

Significant renovations like opening wall gaps are rarely needed when installing ductwork for central air conditioning. In a house with only one level, the air handler is put in the attic, ductwork is run through the joists of the attic to the ceiling of each room, where supply and return vents are made through tiny holes in the ceiling. 

Ductwork is run through closets in split-level homes, going through the floor and ceiling of the closet and down to the lower level. The huge, boxy ducts you may be picturing are essentially a thing of the past; today’s smaller ducts require a majority of little holes to be created to install them.

Putting in Central Air in a Property with Ducting 

If your home already has a working system of air ducts, installing central air might be simple and less expensive. The existing ductwork will be examined by professionals to ensure that it is sound and adequately sealed to carry air through your home effectively.

After that, a split system is installed. This consists of an outdoor condenser and a large metal box housing the evaporator coils, often located in your attic or utility room.

The evaporator coils essentially use refrigerant to remove warm air and humidity from within the home and transport it outside to the condenser. The warm air is subsequently released outdoors via the condenser. The rest of the chilly air is dispersed throughout.

Central Air Conditioning Installation in a Home without Ducts

You still have options if your house lacks current ducting. A ductless central air conditioning system is an alternative to installing air ducts for a conventional split system.

A ductless system needs many blower units inside, a compressor, and a condenser outdoors. Room by room, the heated air is collected and sent through refrigerant tubing to the outdoor condenser as part of absorption.


These systems are typically more expensive than window units and less effective than central heating and air conditioning in Edmonton. Installing ducting or ductless AC in your home would be a significant task, but it is simple for an HVAC expert.
