Buying Guide: Friedrich Through the Wall Air Conditioners Posted on April 8, 2025 Friedrich is a renowned name in the AC industry, and there’s a reason why we carry them in Total Home Supply. Since 1952, the brand has been known for its high-quality, durable, and energy-efficient consumer and commercial air conditioners. Among their extensive product lineup, Friedrich through-the-wall air conditioners stand out as a top choice for homeowners and businesses looking for a permanent cooling solution. This guide explores Friedrich’s through-the-wall units, their features, benefits, and why they are a leading option in the market. What is a Through-the-Wall Air Conditioner? A through-the-wall air conditioner is a self-contained cooling unit installed directly into a wall sleeve, making it a permanent fixture of a room. Unlike window ACs, these models do not obstruct window views and provide a sleek, built-in appearance. Through the wall units are ideal for apartments, condos, offices, and homes where window installation is not feasible or desired. To know more, check out our introductory Guide to Through-the-Wall Air Conditioners. Why Choose Friedrich Through-the-Wall Air Conditioners? Friedrich has built a reputation for designing air conditioners that prioritize efficiency, durability, and comfort. The brand boasts over 70 long years of air conditioning expertise, starting from commercial refrigeration before branching out to consumer ACs. With this legacy, their through-the-wall models come packed with advanced features that continually set new standards for the industry. These include: 1. Energy Efficiency Friedrich air conditioners are engineered for energy savings, with high Energy Efficiency Ratio (EER) and Combined Energy Efficiency Ratio (CEER) ratings. The higher the ratings, the more energy efficient the unit is. Many models are also EnergyStar-certified, meaning they meet strict efficiency guidelines set by the US Environmental Protection Agency, allowing them to be up to 20-60% more efficient than non-certified models in the same class. 2. Quiet Operation Noise levels are a key concern with air conditioning units, and Friedrich addresses this with the brand’s patented QuietMaster™ technology, which uses superior sound-dampening materials and optimized airflow systems to minimize operational noise. Examples of this include extra dense insulation to block outdoor noise, vibration isolating design and components specifically built to minimize operating noise, and precision engineering for maximum airflow and air dispersion at low sound levels. The result is remarkably silent operation, as much as 45% lower than competing through the wall units! 3. Durable Build Quality Friedrich air conditioners are built with high-quality materials to ensure longevity. They feature high-strength steel inner walls, corrosion-resistant coatings, commercial-grade wall sleeves, and advanced filtration systems to maintain optimal performance over time. 4. Smart Controls and Convenience Many Friedrich through-the-wall models offer modern convenience features, such as: Wi-Fi connectivity that allows smartphone control via the Friedrich Go app Smart home compatibility with Amazon Alexa and Google Assistant Programmable timers and sleep mode settings for optimized cooling schedules Multiple fan speeds and precise temperature controls for personalized comfort 5. Eco-Friendly Refrigerants Friedrich uses environmentally responsible refrigerants like R-32, which has a lower global warming potential compared to older refrigerants like R-410A. This makes Friedrich through the wall units a greener choice for eco-conscious consumers, while being compliant with the EPA’s new refrigerant standards.
