Keep your home cool and comfortable all year round with window air conditioners from Ace Hardware. Browse window AC units in various sizes to find the option that best fits your space, then explore features and accessories for all your home cooling needs.

Find the Right Window Air Conditioner for Your Home

Window unit air conditioners are popular because they offer an efficient, low-maintenance way to keep your home cool. While many portable air conditioners need to be emptied by hand or occupy valuable floor space, casement window air conditioners automatically move moisture outside for an easy-care option.

When shopping for an air conditioner for a sliding window, consider the size of the room where you'll install the AC. You'll notice that each window AC unit lists a BTU number, which measures how much heat the window AC unit can remove per hour. Follow these simple guidelines to match the size of your room to the best BTU measurement:

  • 100 – 350 square feet: 5,000 – 8,000 BTU
  • 350 – 550 square feet: 9,000 – 12,000 BTU
  • 550 – 1,000 square feet: 14,000 – 18,000 BTU
  • 1,000 – 1,500 square feet: 18,000 – 24,000 BTU

Window Unit Air Conditioner Features

The best window unit air conditioners do more than just cool the air—they come with helpful features for programming, cleaning, and more. Explore a few of our popular window air conditioner features to find the best fit for your home:

  • Low Noise: When you're looking for a quiet window air conditioner, browse models equipped with a low-noise airflow system, which is perfect for bedrooms, guest rooms, and other sleeping spaces.
  • Remote Control: Turn your unit on and control its speed from the comfort of your couch with a convenient window air conditioner with a remote.
  • Wi-Fi Control: Adjust your temperature settings from wherever with a smart window air conditioner that’s controlled by Wi-Fi.
  • Energy Saver Mode: Save power and money with eco-friendly energy-saving settings.
  • Washable Filter: Reduce waste with reusable filters for your window AC
  • Self-diagnosis: Don't worry about wondering when to change the filter—look for models equipped with a self-diagnosis feature to alert you anytime you need to perform maintenance on your unit.

Window Air Conditioner Filters and Accessories

Once you're all set with the perfect window air conditioning unit for your home, keep it running smoothly with the right AC filters and accessories. Shop air conditioner parts and accessories to make maintenance and repairs easy, then browse our wide selection of air filters for everyday use. With various sizes and performance ratings, air filters are the perfect way to remove dust, bacteria, and allergens from the air. Check the specifications of your AC unit or air purifier to see how often your filter needs to be replaced.

Shop Window-Mounted Air Conditioner Units at Ace

Household fans are great options for staying cool, but sometimes circumstances call for something with more cooling power. You’ll find everything you need to keep your home cool and comfortable with window air conditioning units at your nearest Ace.

Available from brands like Perfect Aire, browse our small window air conditioners for compact spaces or shop for high-capacity heating and cooling systems for larger spaces. You’ll also find thermostats and heating supplies as well as exhaust fans for extra airflow.
