HVAC systems are the single biggest consumer of energy in the home. Proper design and installation of your AC system can dramatically reduce your energy bill.
An undersized system will not be capable of keeping you cool when you need it most. It will also struggle in normal conditions resulting in more frequent service and repairs.
Oversized systems cost more upfront. They cycle on and off reducing their ability to remove moisture from the air. That moisture, or humidity, is the key cause of discomfort for most people. Short cycling also causes your equipment to wear out faster.
To ensure your AC system is exactly right for your home Absolute Precision will take the time to understand your needs and calculate the cooling requirements of your home.
As a general rule of thumb we can use the map and data from the U.S. Dept. of Energy to determine a starting point.
Here in Massachusetts we’re in the green zone. Before calculating other factors we can see in the chart that a 2100 sq ft house requires about a 3.5 ton air conditioner.
A few other factors would include the size and orientation of windows, insulation levels, as well as the number of occupants. Homes with energy efficient windows and insulation would require less powerful equipment while homes with skylights or large south facing windows would need more.
The location and condition of ductwork plays a role in the efficiency of central air conditioning systems in both new installations as well as upgrades. Ductwork installed in non conditioned spaces, such as attics, unfinished basements, or garages needs to be well insulated. Older ductwork should be inspected and resealed wherever possible as in all likelihood it is leaking.
The technical difficulty and thus the expense of installing ductwork in older homes here on the North Shore has always been a major stumbling block for families wanting a central air system. Until recently many households relied on noisy window units for relief. These would typically be only in bedrooms or family rooms making much of the house off limits during heat waves.
The introduction of mini split ductless air conditioning has changed the dynamics for many homeowners. And because mini splits are also heat pumps rooms that were previously off limits in both winter and summer now are reclaimed.
Recent innovations in HVAC mean that you don’t have to put up with noisy energy guzzling window AC units any longer. In older homes, or homes where the cost of installing ductwork is prohibitively expensive you can now enjoy the pinpoint precision of ductless air conditioning.
Residential central air conditioning systems are generally split systems where an outside condenser is connected to an evaporator coil which is installed in the cabinet or main supply duct of a furnace or heat pump. Mini split systems also utilize an outdoor unit but it is connected directly to an indoor unit which has an evaporator coil and fan. Ductwork, which can be leaky, dirty, and inefficient, is eliminated.
Ductless mini split systems, such as Mitsubishi’s has a reversible heat pump allowing you to heat as well as cool the conditioned space.
A central air conditioner here in Massachusetts is typically a split system where an outside condenser is connected to a blower motor inside a furnace. The existing ductwork of the hot air system is used to distribute cold air to individual rooms.
Whether you’re upgrading an existing AC system, adding AC to your existing hot air system, or going with a new central AC installation it’s best to have a qualified HVAC contractor calculate what size air conditioner is right for your home. You can use the chart above for a general rule of thumb but as noted above the size of your system depends on a variety of factors.
We offer a variety of air conditioners, including those with 2-stage compressors and variable speed fan operation. Not only will these features improve the comfort level of your home but also they will provide you with energy savings, too!
