TECH TRENDS: From cloud-based software that can automate processes and optimize service schedules to mobile devices providing real-time updates and documentation to artificial intelligence that facilitates predictive maintenance, technology has become an indispensable part of the HVAC contractor’s toolbox.

Connectivity and Predictive Maintenance
Internet of Things (IoT) connectivity and smart devices, such as smart thermostats, smart meters, and sensors, are being incorporated into new commercial and residential construction at an unprecedented rate, and with good reason. IoT devices provide seamless connectivity, allowing HVAC systems to remotely control and monitor all connected building systems from a single interface. Some building automation systems even enable heating, air conditioning, and “smart” blinds to be adjusted at varying levels in different parts of the building to accommodate changing conditions outside the structure, from rising (or falling) temperatures to direct sunlight.

These systems not only generate real-time data on temperature, humidity, and airflow but also identify energy consumption patterns and potential problems before they occur. By leveraging networks of interlinked sensors, data analytics, and machine learning algorithms to continually analyze HVAC systems, technicians can track everything from airflow imbalances and clogged filters to equipment failures. This, in turn, allows them to schedule proactive maintenance, addressing system malfunctions before they occur and minimizing downtime while optimizing system performance and avoiding costly repairs.

Green Systems
Eco-friendly systems. Energy-efficient solutions. Green initiatives. Whatever you call them, they are in high demand. With consumers looking to save money in response to rising energy costs, that demand is only going to increase in the year ahead.

While the shift to renewable energy sources often translates into the addition of solar panels on both residential and commercial structures, demand for high-efficiency HVAC systems, such as variable refrigerant flow (VRF) systems, geothermal heat pumps, and dual-source heat pumps, are also on the rise, due in part to congressional renewal of the HVAC technology tax credit.

Geothermal heat pumps, for example, depend on the ground and water sources to heat; cool; and, if so equipped, supply hot water. Some models are available with two-speed compressors and variable fans for additional comfort and energy savings. Relative to air-source heat pumps, they are quieter, last longer, need little maintenance, and do not depend on the outside temperature. Dual-source heat pumps, meanwhile, combine the best of air-source and geothermal systems. While not as efficient as geothermal units, they cost significantly less to install and work almost as well.

HVAC technicians are also fielding rising requests for green cooling. In contrast to traditional refrigerants, which cause direct and indirect emissions, green cooling techniques use natural refrigerants — such as carbon dioxide, ammonia, waiter, air, and hydrocarbons (HCs), all of which have zero depletion potential — in combination with energy-efficient appliances. Such refrigerants are relatively cheap and, because they are part of natural biogeochemical cycles, do not form persistent wastes.

Ductless Solutions
It is nearly impossible (not to mention expensive) to update older buildings with air conditioning, particularly if those buildings don’t already have ductwork in place. Even if ducts are already part of the building infrastructure, though, they represent at best an imperfect system, which is regularly plagued by holes and gaps leading to air leaks.

To counter such situations, HVAC technicians are often turning to ductless technology. Because they are relatively small and offer flexibility for heating and cooling individual areas, ductless mini-split heat pumps represent a good retrofit option for structures with non-ducted heating systems. They are also a good choice for areas or additions in which extending or installing distribution ductwork is not feasible. Ductless systems are easier to install than many other types of space conditioning systems and because they have no ducts, do not experience the level of energy losses associated with standard ductwork.

Customer Experience
Wider consumer demand for eco-friendly solutions and a greater understanding of the HVAC technology now available hold the key for HVAC contractors to be successful in the New Year and beyond. It’s no longer enough for companies to simply do good work and offer competitive prices. Customers now expect a seamless experience that ensures immediate service, ongoing attention to handle their HVAC needs, and the use of innovative and sustainable technology to address any problems which arise.

For HVAC companies, that translates into a greater need to train technicians so that they are aware of the latest technological advances. It also means increased use of technology tools, both to market their businesses to tech-savvy consumers and to streamline the work of technicians in the field.

Because online testimonials; informative websites; social media; and convenient features, such as online appointment scheduling, are playing a greater role in consumer selection of service providers, HVAC companies cannot afford to be without a vibrant online presence designed to generate increased awareness of — and interest in — the business and the services it provides.

Similarly, many HVAC contractors are turning to electronic communications to send messages to customers, schedule appointments, deliver invoices, and receive payments. Field service management software, meanwhile, enables HVAC firms to construct calendars that cross-reference team assignments, easily moving workers from job-to-job so there are no wasted service hours while simultaneously tracking costs to provide deeper insights into job profitability. Drones are also gaining in popularity as a viable means to inspect infrastructure and deliver essential parts to technicians already in the field.

Bottom line, the HVAC profession is rapidly changing, driven in large part by technological innovations which are likely to play an even greater role in the year ahead. HVAC contractors who are prepared to embrace these advances will realize more opportunities to meet their customers’ needs and ultimately become more successful in an increasingly competitive field.
