An early start-up can be convenient and appear to not be a problem but carries hidden risks that can undermine the project's success. Consider the following and discuss these issues with your stakeholders to gain support for a temporary system. ![HVAC Rooftop Office Building](https://info.polygongroup.com/hubfs/toolkit/HVAC%20Rooftop%20Office%20Building.png "HVAC Rooftop Office Building") ## Risks of an Early Start **1. Increased wear and tear** Permanent HVAC systems aren’t built to handle construction dust and debris, leading to reduced lifespan, lower efficiency, and potential damage that might void the warranty. **2. Voided warranties** Operating HVAC systems prematurely starts the warranty clock. Using them in harsh construction conditions may void the warranty, leaving owners with higher costs later. **3. Health risks** Dust and debris can accumulate in the system during construction, potentially impacting [air quality](https://www.polygongroup.com/en-US/services/remote-monitoring-and-control/indoor-air-quality/) long after the project is complete, leading to future health complaints. **4. Imperfect tool** Permanent systems heat and cool spaces, but they cannot target areas or turn on/off based on spec conditions making them an imperfect tool for the construction phase. **5. Higher operating costs** Since they are less efficient in unfinished buildings, permanent systems often result in higher costs than temporary systems. Imagine a 70,000 square foot building with 15-foot ceilings. Over the course of 30 days, the in-house HVAC system drives $38,500 in operating cost. Renting and operating a temporary climate solution, on the other hand, costs $32,300. By opting for the temporary equipment, you’re saving over $6,000 in one month. ![20240621\_081153](https://info.polygongroup.com/hs-fs/hubfs/toolkit/20240621_081153.jpg?width=2000&height=1500&name=20240621_081153.jpg "20240621_081153") ## What’s the solution? Temporary climate control systems reduce liability by managing temperature and air quality more effectively, protecting HVAC warranties, and saving money. An effective temporary system is versatile and energy-efficient in accelerating drying processes, protecting warranties, and providing continuous, and clean ventilation. These solutions ensure an optimal climate for curing coatings, manufacturing, and maintaining comfort without compromising the permanent system.
