Xcel Energy, which provides natural gas and electricity to a large proportion of Colorado homes, is offering up to $2,800 in rebates. You’ll need to move quickly to take full advantage: some of the rebates expire on March 31.

Air Sealing and Insulation – Up to $1,850 in Rebates

According to EnergyStar, you could be wasting up to 20% of the energy used to heat and cool your home through air leakage and poor insulation. That’s about the same amount of energy wasted as leaving a window wide open all year long.

Xcel Energy offers the rebate to customers with a qualifying service type (gas only; gas and electric; electric only) and house type (gas heating; gas heating with no central AC; gas heating with central AC; and resistance heat). The rebate is then tiered based on those factors and the improvement(s) you make – air sealing, bypass sealing, or weatherstripping; attic insulation; and external-wall insulation above grade.

Furnace and EC Motor – Up to $850 in Rebates

EnergyStar also reports that heating and cooling account for almost half of the energy use in a typical home, making it the largest energy expense for most homes. By upgrading to a 95% efficient furnace, you can save energy and money.

Xcel Energy offers the rebate to gas and electric customers. The rebate is up to $750 for purchase and installation of a 95% efficient natural gas furnace, and $100 for an EC motor in a new or existing furnace.

Water Heater – Up to $100 Rebate

Earn a rebate on a high-efficiency natural gas or electric water heater that can help you save energy and money on the appliance that consumes nearly 20% of the energy in your home.

Xcel Energy offers the rebate to gas and electric customers. This rebate is a little different, because the deadline is July 31 of the year after the qualifying equipment is installed. It’s also different because you aren’t required to use a participating contractor; you can self-install and still qualify for the rebate.

If Xcel is Not Your Gas or Electric Provider

Check to see if your natural gas and electric providers offer rebates  – the company’s website is a good place to start. Even if your provider doesn’t provide rebates, odds are good you’ll find a wealth of helpful energy-saving strategies.
