An annual inspection of your unit can ensure that the various potential problems mentioned above are detected early, and before they require complete replacement. During this inspection, for instance, a professional might find small cracks in your heat exchanger or a faulty seal in your blower motor. Some manufacturer's warranties even require these annual inspections to maintain validity. Typically, your furnace inspection will cost between $80 and $150 depending on the area in which you live and the professional you work with.
Solar heating is a method where the sun’s energy is collected by panels and converted to reusable energy. The sunlight collected is converted to direct current (DC) by photovoltaic cells in the panels. Then an inverter converts the DC current into alternating current (AC) and the panels send that electricity out and into your home to power things like your TV, computer, game consoles, and air conditioner. The more sunlight you have access to, the more energy you can produce. In some areas, solar powered homeowners can sell or trade the excess power they have accumulated to local power companies.
