Until now, you might have assumed the sun only added to the energy consumed by your HVAC systems. At least, you know your cooling system will have to work harder when the sun is out. By heating up the environment, the sun is requiring your air conditioner to run more often to cool your home on a hot day. However, when solar energy is harnessed as a source of power, it could actually help you spend less on both heating and cooling.

Here are 6 surprising facts about solar tied HVAC systems:
1. Using solar energy may not require a whole new HVAC system. Some systems can simply be modified and solar modules attached.
2. You’ll not only save money on monthly utility bills, but you may also be eligible for federal government and state tax credits to make the install more affordable.
3. Efficient heating and cooling systems that use the sun’s energy increase your home’s value.
4. If the sun’s energy is not needed to power your HVAC systems, it can be redirected to appliances like your refrigerator and entertainment system.
5. Some utility companies allow you to sell back extra energy when your system is tied into the grid. Watch your utility meter run in reverse.
6. Many systems allow you to monitor performance and see how much you’re saving. It’s better than clipping coupons!
