What to Look for in an Air Conditioner Brand

When choosing an air conditioner brand, there are several factors to consider:

Customer Service

Responsive, friendly, and helpful customer service is crucial. Look for brands that offer multiple contact options, such as phone, email, and online request forms. Additionally, check for mobile apps with live chat features. Reading customer reviews can give you insights into the brand's customer support.

Energy Efficiency

Energy efficiency directly affects your electricity bills. Look for units with high SEER ratings, which indicate better efficiency. Consider choosing an ENERGY STAR-certified unit, ensuring it meets federal guidelines for energy efficiency.


If noise is a concern, check the unit's noise score in decibels (dB). Brands often provide this information on their websites, allowing you to choose a unit that suits your preferences.

Smart-Home Features

Smart-home features can provide better temperature control and energy savings. Look for units that can be controlled through a mobile app, voice commands, or remote control. These features allow you to adjust temperature and humidity levels manually or automatically based on your preferences.

Warranty Coverage

A solid warranty is essential to protect your investment. Review the warranty coverage details on the manufacturer's website before making a purchase. Look for warranties that cover both parts and labor for at least 10 years.

How Does a Wall-Mounted Air Conditioner Work?

Wall-mounted air conditioners are sleek and subtle, using advanced technology to cool your space effectively. Most designs feature rectangular units that blow air over coolant coils while expelling warm air outside. These units fit into framed holes on exterior walls and come with specially designed containment wall sleeves for an airtight seal.

Should You Get a Wall-Mounted Air Conditioner?

Wall-mounted air conditioners or ductless mini-split air conditioners can be a cost-effective and easy-to-install alternative to central air conditioning. They are particularly useful for guest houses, studios, sheds, or outdoor workshops. However, if you plan to resell your main home, it's best to avoid wall or window AC units as they may be less desirable to potential buyers.

Our Recommendation

Our top recommendation for wall-mounted AC units is Carrier. Despite being more expensive than other brands, Carrier stands out with its high energy efficiency, low noise levels, and positive customer reviews. Lennox is our runner-up, offering exceptional energy efficiency at a more affordable price.

We highly recommend reading customer reviews and thoroughly reviewing warranty details before making a final decision. Additionally, we suggest obtaining price estimates from at least three different brands to ensure you find the best fit for your needs.

We evaluated each brand's product specifications, SEER ratings, AFUE ratings, and sound ratings to ensure they met industry standards.
