Why The Filter Needs Changed












It’s true. Out of sight usually means out of mind. HVAC systems are
always installed where they can’t be seen, such as in garages,
basements, closets, rooftops or mechanical rooms, making them
easy to ignore. Your Heating and Cooling system is the most
complicated appliance in your home. Most people take for granted
the comfort it provides, until something goes wrong and the system
needs to be serviced or replaced. Our factory-trained Service Techs
understand your heating and cooling system and can eliminate
money waste problems, giving you peace of mind, knowing your
HVAC system is running at peak efficiency.

It is important to note that routine maintenance is
NOT covered under any Manufacturer’s Warranty.

The fact that your system is operating does not ensure that it is operating
at peak economic efficiency. Ignoring your HVAC system until it
breaks down means higher utility bills, personal discomfort, productivity
loss, and even premature replacement of system components.
Lack of proper maintenance can reduce equipment efficiency
by 5-15%. By having your heating and cooling system maintained
with regular tune-ups, your system will be kept at peak efficiency,
which means savings on your utility bills and fewer emergency

• Maintaining mechanical equipment extends its useful life cycle.
• As little as 100th of an inch of dirt on an evaporator coil can
increase operating costs by 5%.
• A dirty blower wheels can reduce air flow over 30%.
• A 23% refrigeration undercharge can cause 53% efficiency loss.
• A 10% reduction in air volume (where excessive) can increase
fan energy consumption by 30%.
• A 15% return air leak from 120° attic can increase operating costs
by 30% or more.
• Well-maintained equipment will help prevent costly repairs in the future.

Filters need to be changed a minimum of every 90 days.
We cannot over-emphasize enough the importance of changing furnace
filters every 3 months, or Air bear filters twice yearly. A restricted filter in the
winter will cause the thermostat to not keep up with the desired temperature.
In the summer, a restricted filter may cause the AC to freeze up.
Check the filter, and change if necessary. Make sure that furnace
access panel is tightly closed, and that the door switch is engaged.
Air conditioning units and heat pump coils should be kept free of grass
clippings, cottonwood, and other debris, whch restrict air flow.
Poor maintenance will shorten the life expectancy of your equipment, as
well as contribute to higher monthly utility bills.

When it looks like it is snowing outside in June, you know the cottonwood
is flying! White fluffy cottonwood seed gets sucked into your outdoor
coil every time your air conditioner is running, creating the equivalent
of dryer lint on the outdoor coil. You wouldn’t go without cleaning the
vent screen on your dryer, and like wise your outdoor air conditioning
unit coil needs cleaned too. You may need to clean your unit more
than once per season!

An air restriction at the outdoor coil is the biggest cause of component
failure in all outdoor units!

Smart homeowners agree – it’s cheaper to prevent a problem than
to fix one. A Planned Maintenance Tune-up program gives you the
security of knowing that your HVAC system is always in prime working
