New Air Conditioning Systems for Old Homes
Often times, older homes fall victim to
hot summer days. Most of them are not equipped with the
proper space to install ductwork for a traditional central
air conditioning system. Of course you have the option of
using mounted air conditions to cool off temperatures, but
then you will have deal with loud noises and an unpleasant
home exterior. Consider some other alternatives that will
work well in your older home.
Retrofit Systems
-
Mini-Split Systems
- Used in homes, where extending or installing distribution
ductwork is not feasible. Mini-split systems are ductless,
individual cooling units that require a conduit, which
houses the power cable, refrigerant tubing, suction
tubing, and a condensate drain to link an outdoor compressor/condenser
and indoor units. Mini-split systems are small in size
and very flexible for zoning or heating and cooling
individual rooms. Typically, models can have up to four
units and are easily installed. Also, mini-split systems
avoid the energy losses associated with ductwork of
central forced air systems. Cost = about $1,500-$2,000
per ton.
-
High-Velocity Systems
- This system works on the principle of aspiration.
Chilled air delivered to a room enters at high velocities.
They use small 2" insulated tubing for supply lines.
This small tubing results in a low impact on existing
space, typically fitting within walls and between floor
joists. Cost = about $8,000-$10,000.
Make sure that when installing an air conditioning
system, you know that bigger is not always a better option.
The size of your home and proper installation play a bigger
role on the success of your system. Consult with a professional
installer about the air conditioning system that is right
for your house.
In addition, with older homes, it is important
to consider your homes electrical system. Central air conditioners
require a dedicated 230-volt circuit and may require 20
to 50 amps of power. Many older homes work off a 110-volt,
60-amp service. If this is the case, you may need to consider
making an electrical service upgrade.
