Standard renovations to keep your home cool

Window treatments

If you have a bit more cash to spend, you can make some changes to your window dressings that will help keep your home cool. From outdoor awnings to shutters to double-paned windows, there are a range of improvements you can make to cool your home.

Awnings or canopies

Awnings and canopies can cover a large area and help prevent the warmth of the sun from leaking into your windows. Three main factors can affect the cost:

  • Size
  • Installation
  • Motorization.

You always have the option of opting for a manual awning to save some money. The material the awning is made of can also increase the cost — basic canvas is priced less than aluminum or a heavy-duty fabric that protects from UV rays.

Plantation Shutters

Plantation shutters are adjustable indoor shutters that can help keep heat out of your home. The price changes based on the size of the windows and the materials used. Solid wood shutters are more expensive than PVC or other faux-wood shutters.

Reglaze your windows

Another option is to reglaze your windows. Window glazing effectively creates a seal between the glass and the wooden frame of the window to limit the heat coming in during summer and keeping the warmth in during winter.

Ceiling fans

You could place ceiling fans in each room to increase air circulation. There are a range of options and sizes, but they tend to range from $35 to $500 and up. If you can’t do the work yourself, you’ll need to get a electrician to install the fans — installation costs vary.

Split system air conditioning

Split system air conditioning units are wall mounted units that also have an outdoor unit that’s usually housed on the side of the house or on the ground outside. These units can usually only cool a single room, or a very small area, and can range in cost from $650 to $1500 or more.

Ventilation and air flow

Adding ventilation fans in your roof will work to push excess hot air out. Another option is to install a whole-house fan in the roof near the center of your home to take all the hot air and push it out through vents that you’ve added. Adding doors to hallways and stairwells can also control where the air flows inside your house.


Adding additional insulation to your roof, wall or floor can help reduce cool air from escaping in the summer. There’s a variety of insulation available, so you should do your research. Different climates and different areas of the home require different types of insulation.

It’s best to get insulation professionally installed. Installers also buy insulation in bulk, so they save on the cost of insulation, which they can pass onto their customers.


Small adjustments to your outdoor landscaping can help direct the breeze to the doors and windows and allow for full airflow in the house.

Adding shade-producing trees or bushes by sunny points around your home will also help keep your home cool.
