29 Heating and Cooling Tips for Your Sustainable Home

Heating and cooling your home can be a major expense, both for your wallet and the environment. 

Fortunately, there are many ways to reduce your energy consumption and minimize your carbon footprint while still keeping your home comfortable. 

In this post, we’ll share 35 tips for sustainable heating and cooling that you can start implementing today.

Best Tips for Cooling Your Home Sustainably

1. Use a programmable thermostat to automatically adjust the temperature.

Programmable thermostats allow you to set different temperatures for different times of the day, so you can save energy while you’re away from home.

2. Use ceiling fans to help circulate air and keep the room cool.

Ceiling fans can help reduce your reliance on air conditioning by circulating cool air throughout the room.

3. Use natural ventilation by opening windows and doors.

On cool days or in the evenings, opening windows and doors can allow cool air to circulate through your home.

4. Install energy-efficient windows to reduce heat loss.

Energy-efficient windows can help keep cool air in during the summer and prevent heat from escaping during the winter.

5. Use window coverings like curtains, shades, or blinds to block out sunlight.

Window coverings can help keep your home cool by blocking out direct sunlight.

6. Seal air leaks around doors and windows to prevent drafts and heat loss.

Drafts can let in hot air during the summer and cold air during the winter, which can make your heating and cooling systems work harder than necessary.

7. Insulate your attic and walls to reduce heat loss.

Insulation can help keep your home cool in the summer and warm in the winter by reducing heat transfer through your walls and roof.

8. Use a whole-house fan to cool your home in the evenings or early mornings.

Whole-house fans can help cool your home by circulating cool air throughout the house.

Tips for Heating Your Home Sustainably

1. Install a high-efficiency furnace or boiler to reduce heating costs.

High-efficiency heating systems can reduce your heating costs by using less fuel to produce the same amount of heat.

2. Replace old, inefficient heating systems with newer, more efficient models.

Older heating systems may be less efficient than newer models, which can result in higher heating costs.

3. Set your thermostat to 68 degrees or lower during the winter.

Lowering your thermostat by just a few degrees can significantly reduce your heating costs.

4. Seal air leaks around doors and windows to prevent drafts and heat loss.

Just like in the summer, drafts can let in cold air during the winter, which can make your heating system work harder than necessary.

5. Insulate your attic and walls to reduce heat loss.

Insulation can help keep your home warm in the winter by reducing heat transfer through your walls and roof.

6. Use a humidifier to add moisture to the air and reduce heating costs.

Dry air can feel colder than moist air, so adding moisture to the air can help you feel warmer without turning up the heat.

7. Use natural sunlight to heat your home by opening curtains during the day.

On sunny days, opening curtains and blinds can allow sunlight to warm up your home.

Tips for Both Heating and Cooling Your Home Sustainably

1. Use a programmable thermostat to automatically adjust the temperature when you’re away from home.

A programmable thermostat allows you to set the temperature of your home according to your schedule. 

This means you can program it to turn down the heat or air conditioning when you’re away from home, and then turn it back up when you’re back. 

This saves energy and reduces your carbon footprint.

2. Use shades, blinds, or curtains to keep your home cool during the day.

Window coverings like shades, blinds, or curtains can help to keep your home cool during the day by blocking out sunlight. 

This is particularly important for south-facing windows that get a lot of direct sunlight. 

By keeping the sun out during the day, you’ll reduce the amount of heat that enters your home, which will help to reduce your cooling costs.

3. Plant trees or install shading devices to block direct sunlight.

Planting trees or installing shading devices like awnings or pergolas can also help to reduce the amount of direct sunlight that enters your home. 

Trees provide natural shade and can also help to cool the air around your home. 

Shading devices like awnings or pergolas can be installed over windows or doors to block out sunlight and reduce heat gain.

4. Use a dehumidifier to remove excess moisture from the air and reduce cooling costs.

In humid climates, excess moisture in the air can make your home feel warmer than it actually is. 

By using a dehumidifier to remove excess moisture from the air, you can help to reduce cooling costs and make your home feel more comfortable. 

A dehumidifier can also help to reduce the growth of mold and mildew, which can have negative health effects.

5. Use a space heater to heat smaller rooms instead of using your central heating system.

If you only need to heat a small area of your home, consider using a space heater instead of turning up the heat in your entire home. 

This can help to save energy and reduce heating costs. Just be sure to use the space heater safely and follow the manufacturer’s instructions.

6. Use draft stoppers to prevent cold air from coming in under doors.

Draft stoppers can be placed at the bottom of doors to prevent cold air from coming in under the door. 

This is particularly important for exterior doors and doors that lead to unheated spaces like garages or attics. 

By preventing cold air from coming in, you’ll reduce heat loss and save energy.

7. Use a fireplace or wood stove to supplement your heating system and reduce heating costs.

If you have a fireplace or wood stove, consider using it to supplement your heating system. 

This can help to reduce heating costs and provide a cozy, warm atmosphere in your home. 

Just be sure to use it safely and follow all manufacturer’s instructions.

Additional Tips for Sustainable Heating and Cooling

In addition to the tips listed above, there are several other ways you can make your home more sustainable when it comes to heating and cooling. 

Here are a few additional tips to consider:

1. Replace incandescent light bulbs with energy-efficient ones to reduce heat production. 

Incandescent bulbs produce a lot of heat, which can make your home warmer than necessary. 

By switching to energy-efficient bulbs, you’ll not only reduce heat production but also save money on your energy bills.

2. Use area rugs on tile or hardwood floors to keep your feet warm. 

If you have tile or hardwood floors, they can get quite cold in the winter. 

To keep your feet warm and reduce the need for extra heating, use area rugs to insulate the floors.

3. Close doors and vents in unused rooms to reduce heating costs.

If you have rooms in your home that are rarely used, close the doors and vents to reduce the amount of space that needs to be heated. 

This will help lower your heating costs and reduce your energy consumption.

4. Use a portable or ceiling fan to help circulate warm or cool air. 

Fans can help distribute warm air in the winter and cool air in the summer, reducing the need for heating and cooling systems to work harder. 

Consider using a portable or ceiling fan to help circulate air in your home.

5. Use a door sweep to prevent drafts from coming in under doors. 

Drafts can make your home feel colder than it actually is, leading to higher heating costs.

Install a door sweep to prevent drafts from coming in under doors and keep your home comfortable.

6. Keep your air conditioner filters clean to maximize efficiency and reduce energy consumption. 

Dirty air filters can reduce the efficiency of your air conditioning system, leading to higher energy consumption and costs. 

Make sure to clean or replace your air filters regularly to keep your system running smoothly.

7. Replace old air conditioning units with newer, energy-efficient models. 

If your air conditioning unit is more than 10 years old, it may be time to consider replacing it with a newer, more energy-efficient model. 

Newer units are designed to use less energy while still providing effective cooling.


In conclusion, sustainable heating and cooling practices can help you save money on your energy bills while also reducing your carbon footprint. 

By implementing these tips, you can make your home more energy-efficient and comfortable, while also doing your part to protect the planet. 

Remember, small changes can make a big difference, so start with one or two tips and build from there.
