In today's rapidly evolving technological landscape, smart thermostats have emerged as indispensable tools for modern households. These devices offer an array of features designed to enhance energy efficiency, such as adaptive learning capabilities, remote access via smartphone apps, and integration with other smart home systems. For consumers, the benefits extend beyond mere convenience; they encompass cost savings on energy bills, increased home comfort, and a reduced environmental footprint. As homeowners increasingly seek ways to optimize their living spaces, understanding the value of smart thermostats becomes paramount in making informed purchasing decisions.
However, the journey to selecting the right smart thermostat is often complicated by a multitude of brand options. Here, brand trust plays a pivotal role in influencing consumer behavior. Trust in a brand can significantly impact how consumers perceive product quality and reliability, particularly for technology that directly affects home comfort and energy consumption. A strong brand reputation not only reassures consumers about their investment but also fosters long-term loyalty. As shoppers navigate the crowded marketplace, the brands they trust can guide their decisions, making trust a crucial factor in the overall purchasing process.
To shed light on this critical dynamic, we turn to the insights from America’s Most Trusted® study, which evaluates brand perceptions among consumers. This comprehensive survey aims to uncover how brand trust influences shopping behavior, particularly in the realm of smart thermostats. By analyzing consumer ratings across various brands, the study provides a nuanced understanding of how trust shapes preferences and choices. In the following sections, we will explore the survey findings, examining the key players in the smart thermostat market and the factors that contribute to their trusted status.
The 2025 America’s Most Trusted Study
Initiated over a decade ago, the America’s Most Trusted® study has become a cornerstone for brands striving to understand the profound impact of trust on consumer purchasing behavior. Recognizing that consumer trust is essential for brand success, the study emphasizes how vital it is for companies to cultivate and maintain that trust. With annual updates released every January, this research has established itself as a definitive benchmark for measuring brand credibility in various sectors, including the smart thermostat market.
Building trust is particularly crucial for companies aiming to foster repeat business among smart thermostat buyers. A brand's standing hinges on its ability to fulfill customer expectations, and consumers are more inclined to engage with brands they perceive as reliable. When customers have confidence in a smart thermostat brand, they are not only more likely to make a purchase but also to advocate for the brand within their networks. This sense of trust translates into customer loyalty, as satisfied consumers tend to stick with brands that consistently meet their needs and preferences.
Over the years, Lifestory Research has released the latest findings from this study every January, reflecting ongoing trends in consumer sentiment.

What Is the America’s Most Trusted® Study?
The America’s Most Trusted® study focuses on evaluating brands that offer products or services to consumers in their homes, particularly in the residential new home industry. Instead of attempting to survey every brand, the study specifically targets the largest and most impactful brands in this sector.
How Does the Survey Work?
Conducted throughout the year, the America’s Most Trusted® survey aims to gather consumer opinions while minimizing biases that might arise from external events or trends. This year-long approach helps capture a more accurate snapshot of consumer sentiments.
Participants are surveyed based on specific criteria, such as whether they are actively considering a purchase in a relevant category—like buying a home, faucet, HVAC. Only those who express familiarity with a brand are invited to share their opinions on its trustworthiness, ensuring that the study reflects genuine consumer insights.
The Importance of Brand Awareness
An essential component of the study is brand awareness. Participants are first asked to identify brands they recognize. Only those who are familiar with a brand proceed to answer questions about it. This criterion ensures that only brands with sufficient public recognition are included in the final trust rankings.
Sampling Methodology
The study employs a non-probability sampling design, relying on online panels to recruit participants. Online panels are organizations that have an established relationship with consumers who agree to complete opinion surveys. Lifestory randomly ask consumers questions that identify consumers shopping for a specific product. Qualified consumers complete an online survey in which they are asked a set of questions about specific product brands.
The number of people completing a survey is referred to as the sample size. Each of the America’s Most Trusted studies seek to obtain a sample size that is large enough to be representative. The sample size is also designed to collect a large number of consumer opinions to minimize error and to assure the study results reflect the majority of consumers sentiment about a brand.
Calculating Trust Scores
At the heart of the America’s Most Trusted® study is the Net Trust Quotient Score. Participants evaluate brands based on their trustworthiness through a series of targeted questions. The responses are then categorized into three groups:
Advocates: Consumers who express strong trust in the brand.
Neutrals: Those who trust the brand but do not consider it superior to others.
Antagonists: Consumers with little to no trust in the brand.
These evaluations are quantified using a statistical method called a z-score, which standardizes the responses, allowing for easy comparison across brands. The results are ultimately transformed into T scores, which are more intuitive for understanding how each brand ranks relative to the mean score of all brands surveyed.
