HVAC technicians specialize in the heating, ventilation, air conditioning, and refrigeration industry. In the US, this occupation is a career with both formal and hands-on training. Typically, HVAC technicians earn an associate degree. Training includes classroom lectures, hands-on tasks, and apprenticeship with a professional HVAC technician. After completing training, HVAC technicians can earn certification in air conditioning, heat pumps, gas heating, and commercial refrigeration.
There are two types of air conditioning systems: package and split. Package systems are much simpler to install because the parts are all in one place. They also are less susceptible to damage caused by weather or outside debris. A split system does not have ductwork and is therefore easier to maintain. A split system is usually more durable than a package unit but is more susceptible to damage from pests and rust.
HVAC technicians recommend having a technician inspect your system once a year to make sure it is performing optimally. These inspections should include a pressure test, which indicates if you need to add refrigerant. Additionally, the technician will need to clean or blow out the coils to ensure there are no clogs or spills. The technician will also need to remove any trees or shrubs that are within three feet of the air conditioning unit.
Commercial HVAC systems are more complex than residential systems and need technicians with more specialized training. They have larger parts and are often located in hard-to-reach areas. As a result, commercial HVAC maintenance is more expensive and requires more frequent visits. Moreover, commercial HVAC systems require frequent technician visits, and full maintenance visits are recommended every three to four months.
A commercial building’s HVAC system is a complex network of equipment that needs to be properly maintained to be efficient. Proper maintenance of these systems will help cut down on energy bills by 5 to 40 percent. A properly functioning commercial HVAC system is essential to prevent costly repairs. Moreover, weak parts will reduce the lifespan of your equipment, causing it to work harder than necessary.
Commercial HVAC systems are also important to the environment. Using energy-efficient HVAC systems can improve the air quality and reduce your energy bills. In addition to increasing the air quality, commercial HVAC systems are equipped with economizers, which help flush out warm air and bring in cooler outdoor air. The economizers also use sensors to monitor outdoor air temperature and humidity. However, there are times when economizers or dampers fail to function properly.
An HVAC technician can calculate the size of the system you need, depending on your budget and the size of your home. Often, the calculations involve factors such as sunlight exposure, ceiling height, and insulation. It’s always a clever idea to purchase the most energy-efficient system you can afford, since it will save you money eventually.
