Unique conservation tips for winter include sealing ductwork with mastic, a thick paste which can be used on all ducts to provide a permanent seal. That will greatly reduce air leakage into unconditioned spaces under homes or in attics. Most aluminum sleeved duct systems have leakage percentages from 6% to 20% which result in massive energy consumption.

NV Energy recommends replacing inefficient furnaces with high efficiency units. A 98% efficient furnace means you're only losing 2% of what you pay for versus an older 60% unit losing 40%.

Installing closed cell polyurethane foam insulation is highly effective for extreme climates because of its high R-value per square inch, high expansion rate reducing waste, and its low permeation rating which helps seal walls and building envelopes.

High solar gain Low-E glass products are well suited for buildings located in heating-dominated climates such as Northern Nevada. This Low-E glass type is the product of choice for passive solar design projects. To reduce heating, select the highest SHGC (solar heat gain coefficient) you can find (usually 0.30 - 0.60 for the U-factor ranges required in colder climates) so that winter solar gains can offset a portion of the heating energy need.

Optimize air flow in your home. If air flow in your heating and cooling system is too high or too low, you may experience comfort problems and higher utility bills. A licensed contractor can test air flow and make any needed adjustments for optimal performance.
Do not close off air vents leading into the home. Even if a room is not used, that hot air needs to enter the house and collect back through the return air register to be re-heated. Closing these vents and rooms provides no advantages and can raise your energy use.
