One ton equals 12, Btu per hour. Why is getting the proper size unit so important? An undersize unit won't be able to cool rooms down completely on the hottest days and will cost more to operate because it has to run longer than a correctly sized unit.
An oversize compressor also costs more to operate because it simply takes more electricity to run a bigger unit. And an oversize unit doesn't lower humidity effectively.
That's because it cools the air so quickly that it shuts off before it has a chance to circulate the proper volume of air past the coils to extract the necessary moisture. The result is a room that doesn't seem as cool as the temperature indicates. In fact, the room can feel clammy and damp. After determining the size of the unit, your contractor should talk to you about efficiency, which is expressed by the seasonal energy-efficiency rating SEER.
The higher the SEER, the less it costs to operate. These units have lower operating costs, tend to be higher quality, have more safety features, better sound shields and lower voltage requirements. In general, the higher the SEER, the higher the initial cost for the unit. Next, you must decide what type of system to buy. There are two kinds. A "package system" gangs the condenser, which cools the refrigerant and exhausts warm air, with the fan-and-coil system, which cools and blows the air.
The ducting connects directly to the unit. This is essentially a large wall air conditioner with ducts. But package systems are rare. With a "split system," the condenser is outside the house and the fan-and-coil system are inside; they're connected to each other by pipes that carry refrigerant.
If you have a forced-air furnace, the refrigerant pipes are connected to a cooling coil system fitted into the furnace air handler. Sometimes it goes right into the existing plenum. If that won't work because of space limitations, the contractor will fabricate a separate sheet-metal plenum. If you don't have forced air, the fan-and-coil system is typically placed in the attic, where it will deliver cool air through ducts. There are two types of central AC units: split-system and packaged. A split system involves an outdoor unit and an indoor cabinet, while the packaged type sits in a cabinet either outside or on the roof of your home.
Packaged units are the ones which can also function as a heater with the addition of electric heating coils or a gas furnace. Of course, choosing the right size system will also impact your energy costs, so picking the appropriate system is crucial.
Hiring a professional eliminates the need for you to do anything other than sign off on the work and pay the bill. In most places, the local government requires permits for many home improvement projects, including replacing or installing large-scale appliances like home heating and cooling systems.
Contractors and HVAC professionals can obtain the proper permits for you, making the job smoother concerning timelines and getting things done quickly.
With most new installs, HVAC pros offer maintenance plan s for these systems. You may also need to finance the pre-installation work, potentially including pouring a concrete slab or making modifications to fit the new assembly on your roof. However, the professional installer will handle the details of the job. While rural living has many perks, getting items delivered and installed is not one of them!
For those itching to do a DIY job, there are a handful of perks to going it alone. Here are the top positive benefits of installing your new AC unit on your own.
While the cost of the AC unit is likely higher when you purchase it on your own many companies enjoy significant discounts with AC unit manufacturers when they buy directly from the brand , you will save on installation costs when doing the job yourself.
Many homeowners enjoy completing projects on their own because it requires them to learn more about the materials and processes used. If you plan to maintain your own AC unit, it makes sense that you will want to install it from the ground up.

This cycle repeats as needed to maintain the temperature set at the thermostat. Today, most houses come with the ductwork already installed and ready to move air on day one. When a house already has a forced-air central heating system, it is possible to modify the existing ductwork to accommodate central air conditioning. Some century-old houses, however, do not have any form of ductwork in the attic, basement or crawlspace.
For older buildings and homes without ductwork, there are ways to install central air conditioning without compromising the unique architecture. One option is a ductless air conditioner, which uses compact indoor units and space-saving tubing instead of traditional ductwork. Fujitsu-brand ductless units are popular choices for heritage homeowners who are installing central air conditioning in Toronto and the GTA.
