To qualify for Cascade’s rebates:
- Homeowners must be on residential rate schedule 503 (work was completed at a residential address, not a commercial business)
- For heating and weatherization rebates, homeowners must use natural gas as your primary heat source (not a back-up for an electric heat pump); or

We offer rebates on qualified equipment for new and existing homes. Some projects may be eligible for additional tax credits or rebates.

A “Combi” system is an appliance that can do two things well: Heat your Home and Provide you with Hot Water
It is a high efficiency appliance that uses condensing technology to heat water and distribute it for space heat and domestic hot water use as needed.
The most efficient combination system uses an indirect-fired water heater; the boiler feeds a heat exchanger inside a storage tank (typically 50-100 gallons), transferring heat to the potable water. This system takes advantage of the already-hot boiler during the heating season. Condensing boilers have a long life, 30 or 40 years compared to 10 to 15 years for a standard storage-type water heater.
The system can be configured to provide space heat via hydronic heat (like piping in the floor, or radiators placed throughout the home), or a hydronic Air Handler can be installed for heat distribution

Yes, $50.00! Your model must be selected from the ENERGY STAR certified Clothes Washer list:
$75.00! Your model must be connected to home WIFI. The unit does not need to be ENERGY STAR certified if installed on or after March 15, 2024.
Yes! This measure is the perfect marriage between Insulation and Air Movement. Think of your house like a person, standing outside, without a coat. On a nice day, you are comfy and don’t need a coat. Then the temperature drops. Installing insulation is like putting a coat on your house. Back to your house as a person. It’s cold, and now it’s windy. Your insulation coat works pretty well, but when that wind hits you want to run inside. Air Sealing is like putting a wind-breaker on your house. Just like a ski parka, when you have insulation combined with a wind breaker, you feel warm!
REQUIRED PRESCRIPTIVE AIR SEALING DOCUMENTATION
Must meet sections 4.4 and 6.2 of the 2016 BPA Residential Weatherization Specifications. Must be performed by a CNGC Trade Ally and concurrently with a non-duct insulation install. Attic Insulation must be present.

Prescriptive Air Sealing targets specific areas of your home to reduce leakage but does not require a Blower Door Test. Rather, your contractor will follow the guidelines of Sections 4.4 and 6.2 of the 2016 BPA Residential Weatherization Specification Guide.
Whole House Air Sealing will target these and other areas, using a Blower Door to find air leaks throughout the home and seal them. Whole House Air Sealing also requires specific Washington Department of Commerce Weatherization documentation.
