How can I be sure my Unit is the right size?
Obviously, an air conditioner that's too small won't keep your
home sufficiently cool. But what many don't realize is that an oversized
system will cycle (turn on and off) more than necessary, wasting
expensive energy and possibly putting undue strain on the compressor.
A good contractor, such as Jimmy Burton's Air Conditioning $ Hearing, will determine the optimum size for your home by
making a careful study of your cooling requirements. Window dimensions
and exposure. Floor space, insulation and local climate. Heat-generating
appliances. The direction your home faces. Even the amount of your
home's exterior shaded by trees.
The cooling capacity of the system will be specified in either
Btu/h (British thermal units of heat removed per hour) or refrigeration
tons (one ton being equal to 12,000 Btu/h).
Which air conditioners are energy efficient?
Much like automobile manufacturers, today's air conditioner
manufacturers are required by law to evaluate and rate their equipment
according to its energy efficiency. This rating is known in the industry
as a SEER, or Seasonal Energy Efficiency Rating. The higher the SEER,
the more efficient the equipment.
Most new homes with central air come equipped with a standard
builder's model. However, when replacement becomes necessary, property
owners can upgrade their air conditioning by specifying a more
energy-efficient system.
The Ruud Classic XIV® High Efficiency model, for example, has a
SEER of 14.00, among the highest available. It's significantly higher
than today's standard models, many of which carry SEER's of around 10.
High SEER models are generally more expensive, but can easily
make up the difference by reducing your home energy bills over the long
run.
Are some air conditioners built better than others?
The compressor is the heart of a condensing unit. On a hot day, it works
long and hard. Ruud installs the highly advanced scroll compressor in
every Ruud condensing unit we produce. Scroll Compressors are recognized
by the industry as the leader in reliability, efficiency and quiet
operation.
Other features to look for include louvered steel cabinets that protect the coils from damage and expensive repair bills.
Also, with some condensing units, the fan can be another source
of bothersome noise. Ruud units have a grill design that minimizes air
restriction for quieter fan operation.
Choosing a Furnace System
These days, home owners search for all the value they can find
in every household purchase they make. You're probably no different. So
when the time comes to replace a furnace in an existing central heating
system, or to install a totally new system, you want equipment that
minimizes costs and delivers dependable comfort for your family - season
after season. Here's a look at some things to consider.
What do Good Furnaces Have in Common?
The best furnaces are efficient. They keep a home warm and
comfortable. They provide steady, dependable performance year after
year. And they are quiet, long-lasting and low in service frequency and
cost.
Which Furnaces are Energy Efficient?
When a furnace loses or wastes heat, it requires more energy to
keep your home warm. Some furnaces lose heat through the walls of the
furnace cabinet. Energy-efficient furnaces like Ruud's full line of
state-of-the-art models significantly reduce this loss with a blanket of
insulation that lines the inside of the cabinet walls.
When a gas furnace is not in operation, most send a steady, wasteful
draft of warm household air traveling up the venting system and out the
roof. The Ruud Classic® Series and Classic® Plus Lines - with AFUE
ratings of 78% and better - feature an induced-draft blower that works
in conjunction with a hot surface ignition system to pull hot gases
through the heat exchanger at a constant and controlled rate of flow. As
the burner cycles off, the draft blower stops, keeping the heating air
in the system.
Pilot lights also can be wasteful. The electric ignition in many of
Ruud's furnaces eliminates the need for a constantly burning pilot. This
feature alone gives up to 6% higher efficiency. And in combination with
an induced-draft blower, can improve furnace efficiencies by over 20%.
Most gas furnaces vent combustion by-products and gases by allowing
the warm air to rise naturally. However, on occasion, proper venting of
combustion by-products may be restricted due to blockage, deterioration
of venting systems, malfunctions or other causes.
The Ruud induced-draft blower maintains a constant draft through the
heat exchanger, which assures proper venting of the furnace combustion
chamber. Ruud also features a pressure switch which continuously
monitors venting; and in the event it senses a vent flow restriction, it
will automatically shut down your heating system for your safety.
The most efficient furnaces tap the energy of the hot vent gases -
which can reach temperatures of 500 degrees Fahrenheit, and more. The
Ruud 90 Plus® gas furnace does this by routing the hot gases through a
secondary heat exchanger. This step captures the otherwise wasted
heat-using it to preheat the household air-and delivers AFUE ratings up
to 94.5%
A high-efficiency furnace generally wears a higher price tag, but it
can make up the difference by reducing operating costs over the long
run. And with today's consumer interest in efficiency, such equipment
enhances the bottom line of your home
Are some furnaces better than others?
Definitely. Features to look for include heat exchangers that resist
corrosion, direct-drive blower units, induced draft blowers, pressure
switches, and an insulated blower compartment, which helps minimize
operating noise.
You also should ask your dealer if the manufacturer of the brand
you're considering quality-checks and tests every unit before it leaves
the plant.
And be sure to check out the terms of the Limited Warranty. Quality
manufacturers put a convincing warranty behind their work. Ruud
furnaces, which include all the features described here, offer one of
the very best. Even the primary and secondary heat exchangers in the
Ruud 90 PLUS are protected by a Limited Lifetime Heat Exchanger
Warranty.
How to Choose a Heat Pump System
As cold as it gets outside, you'll heat up the productivity
indoors. Ruud has the most comprehensive, feature-loaded lineup in the
heating industry. Our super-efficient technology provides savings on
both gas and electricity. Whatever Ruud heating option you choose, you
can depend on energy-saving, cost-effective, reliable performance for
years to come.
Are Some Heat Pumps Better Than Others?
Naturally, energy efficiency is important. But when making your
selection, remember low operating costs are little comfort if service
and repair bills are high. Don't be sold on energy efficiency alone.
Ruud is the only manufacturer to install the Copeland® Compliant
Scroll® Compressor, the industry best, in its entire residential heat
pump line.
What Should I Know About SEER and HSPF?
The Department of Energy requires all air-conditioning and heating
equipment manufacturers to evaluate and rate the efficiency of their
equipment on a seasonal basis. These ratings are known as the SEER or,
Seasonal Energy Efficiency Rating, for air conditioners, and the HSPF
or, Heating Seasonal Performance Factor, for heating equipment.
Heat pumps use both numbers. The higher the SEER or HSPF rating, the
more efficient the heat pump. High-efficiency units cost more. But since
operating costs are lower, the payback period may be shorter than you
realize. A high SEER/HSPF heat pump also can add value to your home
which is important to today's energy-conscious home buyers.
Are Exterior Features Important?
Absolutely. Look for features such as a louvered, galvanized
steel cabinet to protect the condensing unit from outdoor hazards. And
make sure the cabinet is powder-painted with a high-quality enamel for
improved durability and appearance.
What Kind of Coils Should I Look For?
Look for copper tubing in the evaporator and condensing coil.
Copper tubing is a good conductor of heat and is virtually immune to
corrosion. And unlike fragile aluminum tubing, copper tubing is
relatively simple to repair in the field.
Are Some Brands Quieter Than Others?
With some units, the outdoor fan can be a bothersome source of noise.
Ruud units have a grille design that minimizes air restriction which
allows the fan to operate more quietly. Also, the fan is mounted on the
underside of the grille. This protects it from the elements and it
directs airflow upward, away from plants and shrubbery.
