Tips for Choosing the Right Mini Window Air Conditioner

May 24, 2021

If you are starting to feel the effects of June, you are not alone. The heat and humidity are starting to ramp up, and our homes should be an escape from that. Unfortunately, sometimes, our air conditioning units don’t have quite enough strength to keep us cool once summer arrives. This is most likely a sign that HVAC maintenanceis needed, but you may have considered purchasing a window air conditioner for some instant relief.  Here are a few tips for choosing the right option for your home!

Selecting the Right Window Air Conditioner


The price of window air conditioners can vary between roughly $200 and $1,000. That is a massive range, and it exists for a few reasons. For starters, there are several sizes available designed to cool specific square footage. Energy efficiency also plays a significant factor in the cost. Cost also varies greatly depending on the features the unit is stocked with out of the box. Here are several features you may want to consider seeking out depending on your specific needs and preferences:

  • Google Assistant or Alexa compatibility
  • Multiple fan adjustment levels
  • Programmable timer
  • Extra-long cord
  • Filter sensors and washable/ reusable filters
  • Specific temperature control
  • Remote control
  • Venting options for airflow control


To properly cool and dehumidify a room, you’ll need to be sure to choose the proper power rating for your window air conditioner. Be sure to check the British thermal unit (BTU) rating on any window air conditioner before purchasing it. Here is a guide you can use to help you select the right size. Be sure to refer to the specific unit’s listed ratings for more specific guidance. Additionally, remember that the size and weight of the unit will increase as its BTU rating increases.

  • up to 350 sq. ft.: 8,000 BTU
  • 350-400 sq. ft.: 9,000 BTU
  • 400-450 sq. ft.: 10,000 BTU
  • 450-550 sq. ft.: 12,000 BTU
  • 550-700 sq. ft.:14,000 BTU

"After being out all day and coming home to a hot house, it was refreshing to get an HVAC company
to pick up the phone. Rob answered and I was able to tell him the inside unit was not running and it was frozen but the outside unit was running fine. He gave me his pricing and a ballpark figure for a new blower motor, if that turned out to be the problem. I gave him the information on the HVAC panel and he said he had a motor if that was it. He arrived Sunday morning, replaced the blower motor and a bad relay switch and two hours later the house was cooling off. He was very knowledgeable and pleasant. He didn't mind my two little boys asking all kinds of questions about his tools and what he was doing. I also thought the repairs were going to cost a lot more than what I paid. We have used several different companies through the years but Rob has been by far the best. We will be using him for all our future HVAC needs for sure and I would recommend him to anyone who asks."

the phone by himself and be able to come by the next hour. Fixed the problem and also check and
service both units we have. Good services and reasonable price. Good job and thank you, Robert!"

"We had a wonderful experience working with Rob Will & Will-Air. We called a few HVAC companies and chose to work with Will-Air because they were so friendly and helpful on the phone. They scheduled an appointment for that afternoon and offered to call 45 minutes before arriving and even bring a plug-in AC unit in case the repair would take two days. Rob Will was honest when diagnosing the issue with the air conditioning and very personable! We will definitely call him back for any future HVAC needs and recommend this company to our friends!"
