What to Look for in an Air Conditioner Brand

Before making a decision, homeowners should thoroughly research air conditioner brands. Wall-mounted AC units are significant investments, so it's important to choose wisely. Here are a few things to consider when selecting an air conditioner brand:

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. Check if there's a mobile app with a live chat feature. Reading customer reviews can also provide insights into the quality of customer support.

Energy Efficiency

Energy efficiency has a direct impact on your electricity bills. Look for units with a high SEER rating, indicating their ability to provide efficient cooling. Additionally, choose brands that offer ENERGY STAR-certified products, as they meet rigorous energy efficiency guidelines set by recognized authorities.


Consider the noise level of the unit to avoid disruption, especially if you work from home, have young children, or are sensitive to noise. Most brands provide noise scores in decibels, allowing you to gauge the unit's sound output. Look for lower decibel ratings for quieter operation.

Smart-Home Features

Smart-home features offer 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 settings and even automate temperature and humidity levels based on your preferences.

Warranty Coverage

Since purchasing an air conditioner is a significant investment, ensure that the brand offers a solid warranty. Review the warranty coverage details on the manufacturer's website to understand what is covered, the duration of the warranty, and any terms and conditions. Look for brands with a minimum 10-year warranty that includes both parts and labor.

How Does a Wall-Mounted Air Conditioner Work?

Wall-mounted air conditioners are sleek and subtle, utilizing advanced technology for efficient cooling. Most units have a rectangular design and operate by blowing air over coolant coils while expelling warm air outside. They are typically installed in a framed hole on an exterior wall with a specially designed containment wall sleeve for an airtight seal.

Should You Get a Wall-Mounted Air Conditioner?

Wall-mounted air conditioners or ductless mini-split systems can be a more cost-effective solution compared to installing central air conditioning, especially for separate structures like guest houses, studios, sheds, or outdoor workshops. However, they may not be the ideal choice for the main living area if you plan to sell your home, as some buyers prefer alternative cooling options.

Our Recommendation

Our top pick for wall-mounted AC units is Carrier. With high energy efficiency, low noise levels, and positive customer reviews, Carrier stands out as the best overall brand. As a runner-up, we recommend Lennox. Their products offer exceptional energy efficiency at a more affordable price.

Before making a final decision, we recommend reading customer reviews and warranty details. Obtain price estimates from at least three brands to ensure you make an informed choice.

How We Chose the Top HVAC Brands

To determine the top air conditioner brands, we extensively researched dozens of HVAC manufacturers. Our rating system considered each brand's mid-tier and high-end product offerings, focusing on critical factors like product specifications, SEER ratings, AFUE ratings, sound ratings, ENERGY STAR certifications, warranty coverage, years of experience, and customer reputation.

We also took into account the brand's ability to fulfill the high-end and luxury needs of customers, such as smart-home integration options, solar-powered capabilities, and additional home comfort control products like air purifiers and humidity control systems.

Ensure that you consider these factors when choosing an air conditioner brand, as they will help you make an informed decision and ensure your home stays cool and comfortable during hot summer months.
