Any discussion about changing the lifestyle within your home, must begin by keeping you, the homeowner, aware of what is available in Indoor Air Quality and what you should expect (demand?) from your HVAC contractor. This lack of consumer awareness (and the reluctance of HVAC contractors to market higher-priced equipment) is the primary reason the air inside so many homes today is both unsatisfactory and unhealthy. We continue that discussion today, focusing on the heating system, which in our area is the heart of a "Total Indoor Comfort System". Some heating systems less than 10 years old for example, have efficiencies in the range of 56% to 70%. Times have changed and equipment dramatically improved. Some of today's heating systems can achieve efficiencies as high as 97%, converting nearly all the fuel to useable energy. These condensing furnaces (with efficiencies over 90 percent) offer the most energy savings. These furnaces achieve their high AFUE ratings by sending flue gases through a secondary heat exchanger, where heat formerly wasted, is now converted to usable energy for your home. Remaining flue gases are then exhausted outdoors through a special plastic-type vent pipe inserted through the wall of the home. This "direct-vent" piping configuration also draws in outside air for combustion, eliminating the old method of using indoor air for the process. Result: Infiltration is reduced ---added, energy savings. But energy efficiency is not the only thing that has changed in the new systems. In older furnaces and even in many standard central heating and cooling systems sold today, the blower runs at one speed, which means the system is either "on or off". Variable
speed blowers use control technology that automatically
changes blower speed based on your home's heating and cooling
requirements. It starts slowly…gradually increasing speed
up to the maximum if needed…instead of coming on at full
capacity all at once. It is estimated that with this feature,
the lowest blower speeds are used 80% of the time. Result: The
dual advantage of more comfort at less cost. Next time, we will discuss in detail, how high technology cooling systems (the second part of a "Climatemakers Total Comfort System") can improve your lifestyle and how easily they can be yours. Until then, if you would like to see an integrated system live, click here. LAST CALL: There are still 5 days remaining
to take advantage of our Annual Fall Heating System 32 Point, "Tune
Up-Check-Up". If you act promptly, you can still get the 20%
discount and reserve the date that is most convenient for you.
