How Does An HVAC System Work?

How Does An HVAC System Work?

ThermostatYour commercial HVAC system controls the movement, quality, and temperature of the air within your building.  The system you have will behave in a repetitive cycle to maintain the quality of the environment you want.  Here are some basic HVAC components that allow that to happen.

Air Intake – This part of the system brings outside air into your building using a fan, thus providing fresh air to the system.

Air Handling Unit – This part of the system is responsible for filtering and adjusting the temperature of the fresh air that is taken in.

Supply Ducts – Your supply ducts take the filtered and cooled or heated air to the locations around your building.  You will find these on the floor or on the walls of your building.

Return Ducts – Your return ducts act in a contradictory way to your supply ducts.  Their job is to take the old air out of a room and recycle it in your Air Handling Unit.

Exhaust Ducts – This part of your system takes any excess air and removes it from the system.  You will find your exhaust ducts at the end of your HVAC system between the return ducts and Air Handling Unit.

Your commercial HVAC system is a very complicated unit.  These are just the basics of how a standard unit functions.  Please consider always using a professionally trained HVAC company for all of your HVAC related service, parts, and maintenance.

Preventative Maintenance Heating Services

Preventative Maintenance Heating Services

industrial heating system maintenance in MOAmerican Services preventative maintenance heating service near Ladue knows that every heating system is different and often times business owners just want a simple customizable preventable heating maintenance plan.  Heating maintenance doesn’t have to be difficult, but the key is in developing an understanding for simple tasks to ensure your heating system remains safe and properly functioning.  Systems that do not operate at their full potential will lead to future problems and unwanted costs.

As a business operator or homeowner wanting to develop a customize a preventative maintenance plan to ensure your heating system is working properly, you will want to begin by inspecting, cleaning, or changing the air filters once a month.  A dirty filter can increase energy costs and damage your equipment.  This is the easiest, most effective preventative maintenance task.

A typical heating service-maintenance check will include checking the thermostat settings and ensuring the heating system can maintain a comfortable temperature.  All electrical connections need to be tightened and motors need to have the voltage checked.  Moving parts will frequently require lubrication and all drains must be checked to ensure they are not plugged.  Lastly, the controls of the system must be checked to ensure safe and proper operation.  Many times these checks are typically completed by a professional but the simpler checks that don’t require equipment can be added to your plan.

Additional items to check are pipes, steam traps, couplings, and fittings that may develop a leak.  A simple visual check will also ensure that radiators, convectors, air intakes and air diffusers are not obstructed.  It is important to ask a service technician for additional suggestions, specific to your heating system, to add to your preventative maintenance plan.

How HVAC Systems Function

How HVAC Systems Function

HVAC Services in Saint LouisAmerican Services Heating and Air Condition knows that HVAC industrial service near Ballwin is defined as heating, ventilation and air conditioning, and is responsible for providing approximately 30 percent of the energy used by manufacturing companies today.

Both the housing and small business industry increasingly depends on HVAC technology.
Every HVAC industrial building installation will be determined by size, shape, and many other combinations of heating and cooling devices. Having a good air system design reduces energy consumption, cools the building, and improves air quality throughout the installation. Equally important is it leaves no footprint on the environment.

Normally, standard cooling installations consist of rooftop units, heat pumps, chillers and basic air conditioning units. Components such as a boiler, furnace, and electric heat can also be included.

Installation of the commercial HVAC system will depend greatly on the design of the system. So you will want to be sure to hire a contractor, such as American Services, familiar with many designs, and industrial building systems. For the basic industrial HVAC system
an air intake that is located at the top or on side of the building brings in air, this is forced through a damper by atmospheric pressure that regulates how much air is brought in.

This air is then mixed with air already in the system, and then routed through a filter to remove large debris including dust and leaves. The second filter removes the smaller particles.
The air then continues on through a fan and is either heated or cooled by coils.  A condensation pan collects any moisture from the coils. The air then moves through the ductwork to expel through the registers heating or cooling the building.  Finally the air is returned by air registers to be mixed with new air or sent out of the building.

Most commonly used in commercial HVAC installation are 3 main types of air conditioners.

– Direct expansion coolers
– Chilled water system
– Evaporative coolers

HVAC industrial installations are very complex. Knowing what is required before installation will reduce costs, prevent improper installation, and ensure good air quality. The key to successful HVAC industrial installation projects is to contract with a knowledgeable HVAC installation
professional such as American Services in St. Louis MO.
