150 homeowners use Cool Calc app to assess heating needs daily

Every day, about 150 new users sign up for an app called Cool Calc, which helps homeowners in the U.S. determine their property’s heat requirements. Surprisingly, over one third of these new users are private homeowners rather than tradespeople. This trend reflects a growing desire among homeowners to take control of the heating system selection process, according to Bill Fiore, the app’s founder and CEO.

The increased interest in understanding heat loss calculations comes at a time when many homeowners are considering heat pumps as a sustainable heating option. These calculations, which measure how much heat a home loses during colder months, are crucial for ensuring the correct sizing of heat pumps. If a heat pump is improperly sized, it can lead to inefficiencies and potentially leave homeowners with chilly living spaces. Fiore notes that many people are skeptical and want to verify the advice given by professionals.

Recent research from Purdue University highlights the risks of relying solely on tradespeople for heat loss calculations. In a study involving approximately 75 U.S. homeowners, researchers found that many calculations overestimated heat loads by two times or more. This miscalculation can result in oversized heating systems, which not only waste energy but can also create uncomfortable living conditions. Homeowners have reported spending over $1,000 for heat loss surveys, with some even paying as much as $2,500, raising concerns about the value of these services.

Experts urge caution when selecting heating systems, particularly as misinformation proliferates online. While Cool Calc plans to integrate AI chatbots to enhance the reliability of its advice, homeowners are advised to remain vigilant and informed. As energy costs rise and climate concerns grow, accurate heat loss calculations have never been more critical for efficient and effective home heating solutions.
