The State of the HVAC Industry

2017年，由于当地经济强劲，HAC/管道行业实现了显著增长. The good news should continue locally in 2018. 在全球暖通空调市场预计将增长的一年里，美国的空调市场预计将继续增长.S. market is expected to post the largest gains in 2018. 这一增长将不仅来自新的销售，还来自对暖通空调服务和维护重要性的日益提高的意识, including smart maintenance.

消费者日益增长的生态意识和技术的影响 helping the modern HVAC industry evolve. 消费者仍然重视舒适，但他们不希望它损害地球或他们的口袋. They’re demanding more efficient heating, cooling, 制冷解决方案和对可再生能源和替代能源越来越开放. 这些消费者需求反映在新暖通产品的上市上.

与大多数行业一样，新技术正在影响暖通空调业务的运作方式. 他们越来越多地收集和分析实时数据，以做出更明智的商业决策，而不是依靠直觉. This trend is impacting a range of factors, including dispatching, HVAC technician and installer compensation, and financial management. 云技术也有助于暖通空调业务的高效运行, especially when they’re on job sites.

HVAC businesses aren’t the only ones using technology. 他们的客户也使用在线媒介来选择和评价暖通空调系统. 这种趋势意味着暖通空调企业必须花时间通过社交媒体与消费者建立联系, ensuring their web presence is mobile-ready, and building their online reputations.

Commonly Used Equipment in This Sector

暖通空调技术人员使用各种不同的天天进行安装, service, and repair heating, cooling, ventilation, 以及为个人和企业客户提供的制冷系统. 这些只是暖通空调公司经常使用的一些天天:

• Boom and scissor lifts:暖通空调技术人员可以使用电梯将自己、暖通空调产品和天天移动到高处. Lifts are commonly used when installing, servicing, 在住宅和商业建筑中维修暖通空调管道和安装暖通空调天天, especially multi-story properties. Electric scissor lifts are especially popular for these jobs, and boom lifts are also used on many HVAC job sites.
• Cranes:一些企业更喜欢用起重机而不是起重机来吊起暖通空调产品. This is common for commercial projects, which require larger, 较重的暖通产品比小型电梯升得更高.
• Basic hand tools: A variety of basic hand tools — including screwdrivers, pipe cutters, hammers, electrician’s pliers, and wrenches — help technicians install HVAC systems.
• Infrared temperature sensors:这些传感器可以在不接触的情况下测试暖通空调天天的温度, so they’re a handy tool for installation and maintenance work. 它们还能比标准温度计记录更广的温度范围, usually between -40˚ and 4500˚F.
• Manifold refrigerant gauges:这些工具显示液体和气体的压力以及HVAC冷却系统内的真空压力. HVAC技术人员在压力测试或为HVAC产品充电时使用这些仪表.
• Carbon monoxide testers这些测试人员检查大气中一氧化碳的危险水平, which may be caused by a faulty furnace, boiler, water heater, etc. If the test is positive, 暖通空调技术人员可以发现问题的根源，并在消费者遭受任何负面健康影响之前为他们解决问题.
• Voltmeters:电压表用于测试暖通空调天天安装后和定期维护期间的电压.
• Combustion gas analyzers:这些工具用于测试以燃气为动力的HVAC天天的燃烧效率, including residential and commercial boilers and burners, after installation or during routine servicing. 它们提供了有关能源效率、温度、draft和压力测量的详细信息. 基本单元显示氧气、一氧化碳和二氧化碳水平的详细信息. More advanced units also give details of nitrogen oxide, nitrogen dioxide, and sulfur dioxide levels in the atmosphere.
• Acetylene torches:这些焊枪在暖通空调天天安装和维修时，用作便携式热源进行钎焊和焊接.

What Do HVAC Technicians Do?

Professionals working in the HVAC sector, known as HVAC technicians, are responsible for the installation, servicing, and repair of heating, cooling, ventilation, and refrigeration systems in homes and commercial properties. They might specialize in installations, servicing, or repairs, or specialize in certain types of HVAC systems. The following are common duties for HVAC technicians:

• 评估客户需求，提出满足客户需求的暖通空调方案. During this process, 暖通空调技术人员解释各种暖通空调系统的好处和它们如何运行, so customers can make the most informed decision.
• Installing HVAC systems. 这可能需要使用吊杆和剪刀式升降机将暖通空调天天移动到多层建筑中所需的位置. 添加泵和风管是这个过程的另一个常见部分.
• 起草并向个人和企业客户销售暖通空调维护合同.
• Performing routine maintenance on installed HVAC systems. Specialized tools are often required for testing.
• 排除暖通空调系统问题，根据需要维修或更换部件或整个暖通空调系统. 这种故障可能发生在暖通空调系统故障或停止有效工作时, or during the maintenance process.

Most HVAC technicians have a set working schedule, 虽然这可能不包括其他公司的正常工作日朝九晚五的时间. 暖通空调技术人员在晚上和周末工作并不罕见. 许多暖通空调技术人员随时可以接到紧急呼叫, 因为在极热或极冷的时期，维修暖通空调系统可能是生死攸关的问题.

Many HVAC technicians work for themselves on a freelance basis. This gives them the greatest degree of flexibility. 然而，一些技术人员更喜欢在一个成熟的HVAC公司工作所提供的稳定性.
