Commercial HVAC Systems— How do they Work?

aboutNot a lot of people understand how air conditioners work. Many often believe that these systems work by lowering the temperature of the air in a certain setting— a very common misconception. Air conditioners actually work by removing whatever excess heat is in a room. It then transfers this heat outside of through the system’s outdoor unit, leaving the indoor space cooler in the process.

Heat is effectively removed as it goes through the refrigerant coils that are located within the indoor units in HVAC systems intended for commercial spaces. The lines of refrigerant will then transfer the excess outside and disperse it. The moment the thermostat set temperature is achieved, the system will then stop the cooling cycle.

Commercial HVAC Service Contracts

A service contract for commercial HVAC enumerates in detail all the services your selected HVAC contractor will perform. A service contract needs to be well-defined and is a critical element towards maintaining a mutually respectable and long-term relationship between a contractor and the business owner. With this, installation of air conditioning systems along with a variety of HVAC services will be performed by the contractor at specific, pre-arranged frequencies and intervals.

Often, the tasks involved will include regular system checkups, cleaning, maintenance and testing. Contractors need to pay close attention to the coils, filters, condensate pans, blowers, drains and ducts. They also need to ensure that maintenance requirements are performed as specified by the system’s manufacturer. Regular maintenance needs to be carried out on a regular basis to ensure that the unit’s warranty will not get voided.

Also, emergencies to the HVAC system as a result of system malfunctions and other similar issues will be the responsibility of the contractor. They will also need to be responsive and must always have a standby team that will be ready to respond in the event that emergencies occur.

Is Commercial HVAC maintenance necessary?

commercial hvac unitYes. It doesn’t matter whether you plan on fitting in a brand-new commercial HVAC unit or are just looking for a contractor that can take care of the regular HVAC maintenance, check-up and cleaning. You need to have a reliable commercial HVAC contractor on your side. This helps ensure that you can keep the costs of running an HVAC system down.

If you’re interested in getting a new HVAC system installed in your commercial property, an HVAC specialist can help make it easier for you to choose the right size that will keep your energy costs minimal while also maximizing the overall efficiency of the unit. Making sure that you choose the right size for the unit ensures that all of the areas in your office are going to be equally cooled or heated, depending on the season.

In terms of maintenance, you will want to hire a contractor who will be responsible for keeping your system working at the higher standards of energy efficiency. This ensures too that malfunctions and issues are going to be noticed way before they escalate into more serious concerns.  Maintenance contractors for HVAC systems will carry out regular inspections to ensure that the system gets to function with utmost efficiency. They will also make sure that the cleaning vent air filters get regularly replaced along with components that are beginning to show wear and tear.

Commercial HVAC maintenance management

An HVAC system is an expensive investment, so you want to make sure that it is provided with regular maintenance to allow it to last long and for it to remain efficient the whole time. Waiting until your system starts to malfunction before taking any action is only going to make repairs costlier compared to what you would normally spend if you are just getting the HVAC system regularly maintained.

The frequency of your maintenance schedule is going to depend considerably on the age, size and type of commercial HVAC system you have installed. Ideally, an HVAC system needs bi-annual maintenance. This should be done once in the fall and once in the spring to get your system ready for the heating and cooling season.

Spring maintenance steps for commercial HVAC

  • Replacing air filters
  • Cleaning the condenser coils and evaporator
  • Testing the fan and blower motor
  • Lubricating the motor as well as the rest of the moving components
  • Checking the refrigerant levels
  • Checking the thermostat
  • Checking all the safety controls
  • Inspecting the wiring
  • Lubricating or replacing the belts
  • Checking for any unusual noises or smells
  • Checking the ducts
  • Cleaning the outdoor units

Fall maintenance steps for commercial HVAC

  • Replacing the filters
  • Lubricating the motors as well as the rest of the moving components
  • Testing the fan and the blower motor
  • Inspecting the wiring
  • Checking the heat exchange
  • Checking for unusual noises and smells
  • Checking for potential gas leaks
  • Checking the ducts
  • Assessing the refrigerant levels
  • Lubricating or replacing the belts

While it may seem that both the lists above seem to involve quite an amount of work, making sure that they are performed by a reliable HVAC system contractor will ensure that your unit is going to run seamlessly all year round. Once you select an HVAC company, they will then evaluate the system and come up with a maintenance schedule as frequently as your system requires it.

Costs for commercial HVAC ducting replacement

Addressing problems concerning your worn-out or old HVAC ducts is equally important as getting a new system fitted in.

Failing to pay attention to your commercial ducts will reduce their overall efficiency. Without regular cleaning and proper maintenance, the HVAC system may not work as effectively since the free-flowing air will be prevented throughout our property. You’d be surprised to know that this can reduce system efficiency by as much as 40%.

Old and worn-out ductworks tend to be susceptible to cracks and leaks which are to be expected with equipment that is experiencing wear and tear. If this happens to your system, the best choice to go for is to overhaul the ductwork.

When is the best time to replace commercial HVAC ducts?

In the event that patching up the ductwork is no longer doing its job, the ductwork seems to require more frequent repairs, the repairs need to be performed in areas that are hard to reach or if there just seem to be way too many areas of the ductwork that require repairs, getting the whole thing replaced is the more practical option. This is a reality that owners of older commercial properties have to face as there’s a very good possibility that the ductwork might not match the green standards that are being implemented today. A ductwork’s age can be a dead giveaway of how likely it is to be riddled with damages and when they do, they will become inefficient.

Commercial HVAC duct replacement costs

Costs for HVAC installation and replacement can differ from one project to the next as there will be a number of factors that will have to be considered before a price can be quoted. The age of the building will need to be taken into consideration. How old the ductwork is will need to be taken into stock as well. How big the building is will also be looked into. The variety of temperature zones in the building will also be factored in when naming a price. Asking for a free quote from a reliable local commercial HVAC contractor is the best way to go.

 

Commercial HVAC maintenance benefits

A commercial HVAC system that is neglected and isn’t getting the proper maintenance and looking after it needs cannot be expected to perform as efficiently as a well-maintained system would. As a result, a neglected system can lead to higher energy costs and the overall comfort inside your commercial premises will be at risk as well. With regular maintenance to your commercial HVAC system, you can expect your business to improve in the following ways:

  • Reduced possibility of malfunctioning equipment
  • Lower electrical bills
  • Longer life expectancy of the HVAC system
  • Decreased chances of needing emergency repairs
  • Safer operation
  • More comfortable space for you and your employees
