Don’t heat or cool the outdoors:

  • Close windows and doors when running the furnace or air conditioner.
  • Inspect doors and windows for gaps or cracks, and seal with weatherstripping, caulking, or foam insulation. 
  • Use plastic film on windows and draft snakes, sweeps, and weatherstripping for doors to seal your home from cold drafts.
  • Adding insulation and sealing air leaks can reduce heating and cooling costs by 15% or more.

If you have air registers, make sure they are clear of furniture or other obstructions so that air can circulate. 

Cold Weather Tips

  1. Set your thermostat at 68°F during the day, and lower it at night or when you are away.
  2. Open curtains, blinds, and shades during the day to let the sun help to warm your home, and close them at night.

Warm Weather Tips

  1. Set your thermostat at 78°F and use a simple box fan when you're in the room to reduce air conditioning costs.
  2. Close curtains, blinds, and shades during the day and open windows at night to take advantage of free, cool, evening air.

Smart Thermostat

Install a programmable or smart thermostat

A smart thermostat can be programmed to cool or heat spaces in advance rather than maintaining a constant temperature.

Check with your local utility to see if they offer rebates or free thermostats. If you schedule a home energy audit, the visit often includes a free programmable thermostat, installed.

Learn more about programmable thermostats.

Maintenance

Get your heating system tuned up annually and replace furnace filters monthly.

Emergencies

If your furnace stops working and you can't afford repairs, contact the Energy Assistance Program (EAP), usually your local Community Action Agency.

Lighting

Turn off lights when you are not in the room or when you can use natural light.

Replace incandescent bulbs and CFLs with LEDs.

 

Make a plan for when you should replace appliances and equipment.

Appliances lifetimes vary based on how they're used, if they're serviced, and many other factors. The best way to prepare for purchasing energy-efficient models is to know a little about your current appliances. If you make a plan for upgrades before something breaks down, you can take advantage of incentives from your local utility and other programs. Log the appliances in your home below and make a plan. 

Appliance Upgrade Plan

Appliance  Date of installation  Last serviced Average lifespan ENERGY STAR? When to replace
 Space heating    

 Boiler 10-30 years

 Furnace 15-20 years

   
 Air conditioning      15-20 years  

 

 Water heater      8-12 years  

 

 Range/oven      13-20 years  

 

 Refrigerator      14 years  

 

 Dishwasher      10 years  

 

 Washing machine      10-13 years  

 

 Dryer      10-13 years  

 

 Other:         

 

Consult Energy STAR's "When is it time to replace?"

Kitchen Appliances

Refrigeration

  • Move refrigerators and freezers away from heat sources.
  • Identify leaky refrigerator and freezer doors: close the door on a piece of paper, and if it is easily pulled out, replace the seal or gasket.
  • Check that refrigerator cooling coils are clean. 
  • Defrost the inside of your freezer or refrigerator.
  • Use the power saver feature on refrigerators, if available.

Cooking

  • Cook with your microwave or crockpot to avoid overly heating your space.
  • Consider an induction range or cook top. They're more efficient than gas or traditional electric stoves.

Water heating

  • Turn down the thermostat on your water heater to 120°F to reduce energy use and prevent burns.
  • Wash your clothes with cold water (and don't forget to clean the dryer lint trap before or after every load). 
  • Reduce water heating costs with water-efficient faucet aerators and showerheads. Look for the WaterSense label.

Understand your energy bills

Who supplies the energy to your home?

Find your utility and find out if they provide energy assessments, rebates, or free energy-saving items. It may be important to know how to contact them in case of emergencies.

Your electric and natural gas bills have several types of charges. Actual energy costs and items on bills can be different depending on your utility, but here are the basics:

Energy Charge

The energy charge on your bill is the cost of the electricity or gas you used.

It is billed by kilowatt-hour (kWh) for electricity and therms for natural gas.

Your utility reads your meter to determine the amount of electricity or natural gas used.

Understanding kW and kWh

Kilowatts (kW) are a rate of energy use; kilowatt-hours (kWh) are a quantity of energy used.

For example, a microwave might use electricity at a rate of 1 kW. If the microwave is used for 2 hours, it will use 2 kWh of electricity. 

Understanding therms

Therms are a unit of heat.

One therm is equal to approximately 29 kWh and can be provided by about 97 cubic feet of natural gas. 

Service Charge

The service charge is a flat monthly fee that you pay every month to have access to energy.

Even if you do not use any energy in a given month, you will still be charged for access under the service charge.

Riders

Many utilities also include “riders” on your bill. Riders are charges for specific aspects of your utility service, such as the cost of fuel.

Riders may be based on how much energy you use or they may be a flat monthly fee.

Taxes

Taxes on your bill vary based on where you live.

Taxes may be flat fees or variable.

If your utilities are shut off or you are behind on payments

CONTACT YOUR UTILITY

Minnesota’s Cold Weather Rule (CWR) is a state law that protects you from having your electric or natural gas service shut off between October 1 and April 30. If you are behind on your bill payments, contact your utility company to find out if you qualify for CWR protection, and sign up. You must set up a payment plan and keep it or you may be disconnected.

All natural gas and electric utilities must offer CWR protection to residential customers. You can set up a CWR payment plan any time during the CWR season. The utility must set up a payment plan that is reasonable for your household circumstances. If you and your utility can’t agree on a payment plan, contact the Minnesota Public Utilities Commission at 800-657-3782, or email [email protected] and they can help you work with your utility. 

You can also contact your local Energy Assistance Program to help with energy bills.

Find out if you qualify for the Low Income Home Energy Assistance Program. If your income is too high to qualify, you should still work with your utility to establish a payment plan.

Tips for Your Home

Information specifically for renters, residents of manufactured homes, single-family home buyers, and landlords provide ways to be comfortable, safe, and efficient.

Know before you buy

Inspect the Home

Assume that the home is being sold “as is.” Get it inspected by a professional who is a member of ASHI or InterNACHI. It can be a good idea to request previous utility bills to estimate heating and cooling costs in the home, as high bills could indicate that energy improvements need to be made.

Before buying a home, there are four areas you should inspect, with the highest opportunity for energy savings in Minnesota’s climate:

  1. Attic Insulation: Air leaks allow air from inside a house to enter the attic, potentially causing comfort issues, ice dams, and moisture issues. Sealing these leaks and adding insulation will improve a home’s durability and save energy.
  2. Heating System: Forced air furnaces typically have a 20 year life, and boilers should be replaced after 25 years. 
  3. Wall Insulation: Walls with little insulation are cold and drafty. Dense packing walls with insulation reduces home drafts and improves home comfort. This will also reduce energy waste and save money. 
  4. Windows: Windows should be double-pane, or single-pane with storm windows. Storm windows can be installed on the exterior of single-pane windows to cost effectively reduce energy usage, reduce drafts, and improve comfort.

Know before you rent

Ask to see recent utility bills so you know how much they might cost.

What utilities does the house or apartment have?
If there is more than one unit in the building, are there individual energy meters for each unit or is there one shared meter? Electric, natural gas, delivered fuels (propane or fuel oil), other?

Who pays the utilities: renter or landlord?

Your landlord can be your partner

Talk with your landlord about energy:

  • Ask if there’s been an energy assessment or audit recently.
  • Ask for help installing a programmable thermostat.
  • Find out whose responsibility it is to change the furnace filter monthly and get the furnace serviced regularly.
  • If appliances are old or need replacement, request ENERGY STAR appliances that qualify for utility rebates.
  • Ask for help installing water-efficient faucet aerators and showerheads to reduce water heating costs.
  • Find out how to turn down the water heater to 120°F to reduce energy use and prevent burns.

If your heat stops working

Contact your landlord.

MN law requires that landlords maintain rental properties so that they are “fit to live in” and “kept in reasonable repair.”

If your utilities are shut off or you are behind on payments

If your landlord pays your utilities:
Contact your landlord to alert them that utilities need to be paid. If your landlord still does not pay, you or a group of tenants may pay the utilities and deduct the payment from your rent.

  1. Notify your landlord in writing that you plan to pay the utilities if they are not paid within 48 hours. If it is winter and the heat is not on, a shorter time period is acceptable. 
  2. If the utilities are not reconnected in that time, a tenant may pay the amount due for the most recent billing period. Submit a copy of the receipt to your landlord with your rent. You may deduct the amount paid from your rent payment.
  3. If you live in a building with five or fewer units, you or another tenant may establish an account in your name, pay the monthly utility bill, and submit a copy of the receipt with your rent payment each month.

If you pay your own utilities:
Minnesota’s Cold Weather Rule (CWR) is a state law that protects you from having your electric or natural gas service shut off between October 1 and April 30. If you are behind in paying your electric or natural gas bill, contact your utility company to find out if you qualify for CWR protection, and to sign up.

Know Before You Buy

The Data Plate is a sheet of paper located in a kitchen cabinet, an electrical panel, or a bedroom closet. It should never be removed! If it is missing, you may not be able to find out whether the home was designed for Minnesota’s cold climate. A missing data plate may also mean that the home was manufactured prior to 1976, when efficiency standards were implemented for manufactured homes. There are several pieces of information on the data plate that are particularly important: 

  1. When was the home manufactured?
  2. Some homes were designed only for temporary housing. Make sure the data plate does not include a warning against long-term habitation. 
  3. What is the factory-installed equipment? If the current equipment is different, then you know it has been replaced at some point since the home was manufactured. Check the nameplates on the heating systems (furnace/boiler and hot water) to make sure they are rated for manufactured homes.
  4. What thermal zone was this home designed for? If you live in Minnesota, it is essential that the home be designed for thermal zone 3 (U value of 0.079 BTU/hr·ft2·oF). 
  5. What snow load is was this home designed for? If you live in Minnesota, it is essential that the home be designed for at least 30 lb/ft2. 

Inspect the home

Assume that the manufactured home is being sold “as is.” Get it inspected by a professional who is a member of ASHI or InterNACHI. A few things to look for:

  1. Moisture barrier and insulation should be intact on the underbelly.
  2. Gaps (such as for plumbing entrances) should be sealed against air leaks.
  3. Furnace and water heater must be rated for manufactured homes (this should be marked on the nameplates of the furnace and water heater).
  4. There should be no damage in the area of the furnace, water heater, or bathroom.
  5. Watch for sagging, dark spots, peeling ceiling panels, or warping of the floor, which are often signs of roof leaks or other damage.

Do-It-Yourself Improvements

  • Leaky heat ducts under the floor are a common problem that you can inspect and seal on your own.
  • Seal your home from cold winter drafts with plastic film on windows and draft snakes, sweeps, and weatherstripping for doors. Use spray foam for other gaps, such as around plumbing and electrical entrances. Close storm windows on doors and windows, too.
  • Make sure that the crawlspace under the floor (underbelly) is well insulated.
  • If you need to replace your furnace or air conditioner, install high efficiency EnergyStar units.
  • Heat with your furnace, not portable space heaters which can be the biggest use of electricity in the winter and are also fire hazards.
  • More energy efficiency tips for manufactured homes.
