The HVAC industry is continually advancing as equipment improves and new technology becomes available. Recent law changes have also had a significant impact on the type of cooling equipment available in the coming year. Most of the recent trends and changes are geared toward two interrelated goals: improving energy efficiency and protecting the environment.

New HVAC Refrigerants

Big changes are coming in 2025 as older refrigerants get replaced with more eco-friendly options. For years, R-410A has been the main refrigerant used in air conditioners and heat pumps. It became popular after the phase-out of an older refrigerant called R-22. Now, the government is aiming to reduce the use of refrigerants like R-410A to positively contribute to climate change. Under the AIM Act, production of these refrigerants will drop by 40% in 2025 compared to 2023. This effort also follows international rules, like the Kigali Amendment, that aim to protect the environment. To prepare for this, HVAC manufacturers are switching to new refrigerants like R-32 and R-454B. These new options are better for the environment because they have a lower global warming potential (GWP). While using these refrigerants isn’t required yet, many manufacturers are already getting ahead of the curve. This phase-down will impact homeowners in a few ways:

  • Servicing Costs: As production decreases, R-410A will become more expensive, especially for older AC or heat pump systems requiring recharges.
  • New Equipment Costs: AC and heat pump systems using R-32 or R-454B may have higher upfront costs. This is due to advanced components, additional safety features, and the time required for HVAC technicians to become fully familiar with the new refrigerant technologies.

Full phase-down efforts are expected to continue through the 2030s, with the goal of minimizing the use of high-GWP refrigerants by 2036.

Ductless HVAC Systems

The use of ductless HVAC systems has increased rapidly in recent years, and this trend is set to continue in 2025. Ductless AC and heat pump systems are becoming extremely common in new home construction as they provide an excellent alternative to central HVAC systems. Ductless systems offer significant advantages over central HVAC systems in terms of space requirements, energy efficiency, and temperature control. Ductless systems take up far less space since they eliminate the need for ductwork running throughout the house. Instead, individual indoor units (air handlers) are installed in each room or zone. This allows you to control the temperature in each area independently, eliminating issues like hot and cold spots. It also enables the system to work far more efficiently, helping you save on cooling and heating costs.

Integration of Smart HVAC Technology

While Wi-Fi-enabled smart thermostats have been around for more than a decade, recent advancements have taken smart HVAC technology to new levels. Instead of just allowing remote control via apps, many smart thermostats now integrate artificial intelligence (AI) and work seamlessly with other smart home devices. These advanced units, often referred to as learning thermostats, can adjust programming based on your behavior and daily routines. For instance, many models feature:

  • Motion Sensors: Detecting when people leave, return, or go to bed to optimize comfort and energy use.
  • Geofencing: Adjusting temperatures automatically based on your smartphone's location.
  • Smart Blinds and Window Sensors: Integrating with systems to open blinds on sunny winter days for passive heating or shut off AC units when windows are opened.

These features significantly reduce energy waste while ensuring your home remains comfortable and efficient.

HVAC Electrification

Another major trend for 2025 is the continued push toward HVAC electrification, which focuses on reducing reliance on fossil fuels for heating by promoting all-electric systems like heat pumps. This shift is supported by federal and local incentives. For example, the Inflation Reduction Act (IRA) offers a tax credit of up to $2,000 for qualifying heat pump installations that meet specific energy-efficiency ratings. Additionally, many utility companies provide rebates for homeowners who install heat pumps. Heat pumps are extremely efficient, using at least two to three times less energy than traditional heating systems. Advances in technology have also made heat pumps suitable for cold climates. Modern cold-climate heat pumps can operate effectively in temperatures well below 0 degrees Fahrenheit. High-efficiency systems often feature variable-speed technology, which allows for precise temperature control and further energy savings.

Advanced Indoor Air Quality Solutions

Improving indoor air quality (IAQ) remains a growing focus among homeowners. Integrating IAQ solutions into HVAC systems can create a healthier indoor environment while enhancing comfort. Popular IAQ solutions include:

  • High-Efficiency Air Filtration and Purification Systems: Reducing allergens, airborne contaminants, and germs.
  • UV Lights: Disinfecting the air and surfaces inside your HVAC system.
  • Humidity Control: Humidifiers and dehumidifiers that maintain optimal humidity levels, helping prevent mold growth and dust mites.

Smart technology advancements also allow IAQ equipment to integrate with sensors for real-time monitoring of air quality, humidity levels, and temperature.
