Great service and stunning design can impress guests—but if a room feels hot, stuffy, or has a strange smell, it’s hard to overlook. That’s where HVAC in hotels and resorts plays a vital role. It ensures each space feels just right, providing comfort guests may not see, but definitely feel.

A Quick Look at the History

The journey of HVAC in hotels and resorts began far from hospitality. Early HVAC systems were first designed for factories, not guest rooms. Over time, these systems became smarter, more compact, and more energy-efficient—eventually transforming into today’s guest-focused climate control solutions.

How Modern HVAC Systems Work

Let’s break it down simply. The HVAC process works in a continuous cycle to maintain the perfect room temperature:

1. Pulling in Warm Air

Warm indoor air is drawn into the HVAC unit, where it passes over a cold evaporator coil. This coil cools the air by absorbing heat into a special liquid called refrigerant.

2. Moving the Heat

The heated refrigerant turns into gas and moves to the compressor, which increases its pressure and temperature—prepping it to release the heat outside.

3. Releasing Heat Outdoors

Next, the hot refrigerant flows to the condenser (usually outside), where the heat is expelled into the outdoor air. The refrigerant then cools and returns to liquid form.

4. Repeating the Cycle

Now cooled again, the refrigerant goes back to the evaporator, and the process repeats quietly in the background.
