In one of our previous articles about best places to live in the US, we mentioned that according to the Environmental Protection Agency (EPA) there are several indicators of climate change that are already taking place. According to NASA, rising global temperatures are causing more frequent incidences of extreme heat and humidity, which are having a serious impact on human health. As heat and humidity levels rise, the demand for air conditioners and dehumidifiers is expected to increase while also creating new opportunities for innovation in the HVAC industry.

Before we look at the 50 most humid cities in the US, let’s first take a look at the HVAC systems market and what some of the major market players are up to.

HVAC: A Growing Market with Opportunities for Growth

HVAC systems regulate the temperature, humidity, and air quality of indoor spaces by transferring air between indoor and outdoor areas. They play a vital role in improving the quality of life for people around the world by maintaining humidity at an optimum comfort level and keeping the indoor environment healthy.

According to a report by Fortune Business Insights, the global HVAC systems market size was valued at $150.04 billion in 2022. The market is projected to grow at a compound annual growth rate of 5.5% during 2023-2030, propelling the market to reach a value of $228.74 billion by the end of the forecast period. The changing global climatic circumstances and the need to maintain a comfortable ambient environment indoors and in buildings are key factors that are expected to have a positive impact on the market over the forecast period. Previously, in an article about the oldest buildings in the world that are still in use, we discussed that the construction industry is poised for growth. Construction of private and government offices, convention centers, hotels, hospitals, and theme parks is expected to further augment market growth. Buildings use HVAC systems to maintain a comfortable environment inside. The growing construction industry is driving the demand for HVAC systems and new installations, especially in hot regions.

On July 24, Reuters reported that as Southern Europe battles extreme heat, people have started investing more in air-conditioning to keep cool. According to the report, air conditioner sales in Italy soared during a recent heatwave. Unieuro S.p.A. (BIT:UNIR), the largest Italian retailer of consumer electronics and household appliances, also reported a doubling of sales of air-conditioning products in the week to July 21 this year, compared to the same week last year. The report also mentions that according to a consumer organization in Spain, OCU, the rise in electricity prices previously might have discouraged people from installing air conditioning units, but the rising temperatures and heatwaves this year has led to more consumers investing in fixed units.

A Look at the Top Market Players

Some of the top market players that are expected to benefit from incidences of extreme heat and humidity as well as the flourishing construction industry include Carrier Global Corporation (NYSE:CARR), Lennox International Inc. (NYSE:LII), and Electrolux AB (STO:ELUX-B).
