Income-Qualified Weatherization Program

Weatherization helps individuals and families reduce energy costs and increase the comfort and safety of their homes.


Eligible income-qualified customers can schedule a no-cost weatherization appointment to improve the comfort and performance of your home, all while lowering your energy bills.

What you can expect:

  • A weatherization appointment usually takes 1-2 hours.
  • The occupant does not need to be the homeowner, but must receive written permission from the landlord or property owner before the installation of any permanent products: Property Owner IQW Authorization Form.

Your no-cost weatherization will include:

  • An analysis of your home's heating, ventilation and air conditioning (HVAC) system for operating efficiency
  • On-the-spot installation of some or all of these low-cost, energy-saving products:
    • LED bulbs
    • Duct sealing
    • Programmable thermostats
    • Energy efficient sink faucet aerators
    • Energy efficient showerhead(s)
    • Water heater pipe wrap
    • Water heater set-back
    • Furnace filter whistle
  • Check for water leaks, as well as electrical and gas hazards
  • Inspection of insulation levels

Eligibility requirements:
