Furnace Replacement In Your Future? Right Sizing Is Crucial

Furnace Installation & Replacement Tulsa

A furnace replacement may be one of the more challenging decisions you make as a homeowner, since these systems are complex and involve a number of factors. The right size is critical, not just for energy efficiency, but also for your comfort and the longevity of the system.Before homes were as air tight and energy efficient as they now are, larger equipment was needed to adequately compensate for lower insulation levels and more air infiltration. If you live in an older home and have made any improvements to either the insulation and plugged the air leaks, chances are you need a smaller system than you now have.HVAC contractors use a tool called Manual J to pinpoint the size that you need. This system was developed decades ago and it factors many aspects of your home, including:

• Cubic footage you need to heat;

• Layout of your home;

• Number of windows, their efficiency and exposure to the sun;

• Insulation levels in the attic and walls;

• Air infiltration rates;

• Heat-producing appliances under roof;

• Outdoor landscaping characteristics;

• Preferred indoor temperatures; and

• Age and number of household members.

Once the HVAC contractor finishes the analysis and knows the BTUs you need, he moves onto evaluating your current ductwork, using Manual D.Knowing the precise size you need not only saves you money initially for a furnace replacement, it also saves money over the life of the equipment. When furnaces are too large, they short cycle, which means they turn on and off more frequently. Short cycling increases your energy costs because the more the furnace runs, the more fuel it uses, and a portion of it goes up the flue, which is wasted. Running frequently also increases the wear and tear on all the components inside the system. Your comfort also suffers, since rooms may not thoroughly warm enough.If you'd like more information about furnace replacement, contact Air Assurance.
