You have probably complained of irregularities with your old AC system. Due to the complexity and bulkiness of the older systems, you may not have total control over temperature and humidity in your commercial premises. However, retrofitted units operate intending to improve comfort for occupants.

Longevity

Opting to replace a defective part of your HVAC system gives it new life. You may also consider changing the entire equipment, but it would prove expensive in both short and long runs. Consider retrofitting your unit to increase the lifespan of your current system while still shielding your pockets.

The fact is all commercial heating and conditioning systems and equipment will need replacing at some point. Nonetheless, retrofitting equipment has the above-discussed benefits for long-term solutions. Are you considering this option? Call us today at 408-295-2182 for immediate HVAC attention.

What Are the Most Efficient Commercial Air Handler Options?

Choosing the right commercial air handler can make your business more comfortable, efficient and save you money. This device provides a key element of the heating, ventilating, and air-conditioning (HVAC) system.

What is an air handler?
Air handlers, also referred to as air handling units (AHUs), circulate and regulate the air from an HVAC unit. The AHU forms the backbone of the HVAC system. Its large metal housing contains the blower, cooling and heating elements, fan, its filter chambers or racks, dampers and sound attenuators. It filters and circulates air throughout the building’s duct system.

Efficient Air Handlers

You’ll find three main types of commercial HVAC systems with air handlers. Depending on the size of your building, the following might be right for your needs:

  • single split system,
  • multi-split system,
  • VRF or VRV system.

Single Split System

A single split system provides an affordable system for small commercial buildings. It lets your heating and cooling individual areas or rooms. This makes it a typical solution for cafes, server rooms, small offices, and shops. While you can combine them since you need one outdoor unit for each indoor unit, it adds to the cost and you need space outdoors too for each unit. This can detract from the landscape.

The advantages of more than one single split though are its cheaper than a central system and since each self-contained unit ensures you still have HVAC if one unit breaks down.

Multi-Split System

A multi-split system functions similar to a single split with one key difference – some systems let you connect up to nine indoor units per outdoor unit. These prove popular with doctor’s offices, restaurants, shops, and large offices.

This choice lets you preserve the aesthetic of your building’s exterior while efficiently cooling and heating the interior. You can use more than one type of interior unit and you can combine wall- and ceiling-mounted air conditioning units. Their complexity does require more pipework than using several single splits which drives the cost up.

VRF or VRV

The two acronyms refer to the same technology. Variable refrigerant flow (VRF) and variable refrigerant volume (VRV) share the same meaning. The VRF/VRV option provides the most efficient solution for medium to large structures such as hotels, mixed-use buildings, large offices and retail spaces.

These systems provide reliability and simple controls with shorter installation times. Two types exist: heat pump and heat recovery. The heat pump option works better in open plan areas to provide either cooling or heating to the structure. Heat recovery options let different areas of the building use heating and cooling simultaneously. This makes them ideal for large office buildings with many individual offices. These recovery systems provide the greatest efficiency since they recover waste heat and use it to heat both hot water and other rooms.

How Long Does It Take to Install a Commercial Air Handler System?

Installation of air conditioning units in commercial facilities has become a standard practice for modern developments. The demand for conditioned air in office and business premises continue to grow every year, and here are some of the reasons.

Nowadays, when a customer enters into an office or business premises, they expect to be in a cool and pleasant environment. Presence of fresh and regulated temperatures creates an ideal environment for people to spend more time. If customers spend more time in your restaurant or café, they are definitely going to spend more money, which is an advantage to the proprietor.

In-office settings, employees are more productive when they work in a conditioned environment. In a school setting, students are likely to perform better when they study and take their exams in a comfortable environment. Commercial air handlers do guarantee not only the comfort of the people residing in business places but also their health. The filters in an industrial air handling unit help to remove contaminants that cause various health problems.

Installing commercial air handlers

If you are planning to install an industrial air handling unit in your facility, you have many options to choose from. However, you will have some work to do unless you have a trusted specialist to consult. To start with, you will need to carry out a thorough assessment of your premises to determine the size of the air handling unit required to cater for ventilation needs in your premises. Once the evaluation has been completed, a commercial air handling unit specialist will help you to choose the right equipment for your commercial facility.

How long does the installation take?

This is a commonly asked question by many people who want to install a commercial air handling unit for the first time. To be honest, there is no definite answer to how soon the technicians can complete the project of installing a commercial air handling unit. The time taken to install this unit depends on several factors.

The size of your commercial facility

Do you want to install a conditioning unit in a 5000 sq./ft or a 10,000sq/ft commercial facility? The project can be completed in one day if it is in a small facility and without any complications. However, the project can run for a few days or even weeks in more extensive commercial facilities.

Is it a changeout of full system replacement?

We have two types of commercial air handling installations: a full system replacement and a changeout. A changeout refers to when specific components of the air conditioning unit are replaced while the rest of the system remains intact.

How often will I need to replace my commercial air handlers?

An industrial facility is full of people and equipment that generate much heat, making it uncomfortable to work in the interior spaces. During such times, a commercial air handling unit comes in handy as it plays a crucial role in making the interior spaces habitable. These units help in dehumidifying, cooling, filtering, ventilating, and distributing the indoor air.

The working of a commercial air handling unit is more complicated than a residential HVAC system. These units consist of several components that play a crucial role in maintaining air quality in an industrial facility. With continued use, the parts of a commercial air handing unit wear out. They, therefore, need to be replaced regularly to maintain the quality of air. But how often do you need to replace commercial air handlers?

Change filters 3-6 times a year

Commercial air filters play a crucial role in maintaining the quality of air in a business set up. You may need to change your unit’s filters up to six times in a year, depending on whether the air handling unit is used in a controlled or harsh environment.

Commercial air handlers used in switching offices and data centers may need to be changed 3-4 times a year. This is because these filters may take long to accumulate dust and debris.

On the other hand, commercial air handlers used in harsh environments such as chemical factories, medical facilities, and military facilities may require frequent changing. Mostly, the need to replace air filters in commercial settings is determined by maintenance sensors. If the sensors indicate changes in pressure, temperature, and airflow, it’s a good time to change the filters.

Clean dampers annually

A malfunctioning damper is one of the most common problems in a commercial air handling unit. If the damper malfunctions, it can cause significant changes in the indoor air quality as well as increasing electricity bills. The primary function of the damper is to regulate the activity of a compressor. For optimum functioning, dampers should be cleaned and adjusted annually.

Inspect moving parts two times a year

A commercial air handling unit has several moving parts which include the bearings, fan, and the belts. Although these components do not have a direct impact on the indoor air quality, they should be inspected semi-annually as part of a preventive maintenance plan.

Fixing air leaks in the cabinet and supply duct annually

A routine annual checkup should include replacement of screws, search for air leaks and replacement of gaskets. Maintaining the integrity of the supply duct ensures that air does not leak out of cracks that may be in the supply duct.

How Is Residential AC Different From Commercial AC?

When installing air conditioning, the requirements for each process differ based on what type of AC is needed. For residential AC, a central air conditioning unit is installed in the homes and apartment complexes of individual renters and owners. For commercial AC, a special installation is required as the air conditioning for commercial buildings is significantly different from residential AC.

With commercial AC, more power is needed to cool a commercial space. For the likes of businesses and office spaces, AC units need to be able to accommodate for all the body heat emanating from the staff, as well as excess space in office buildings. Moreover, with such a complex and sizable AC system, installing commercial AC requires a certain level of technical skill.

What to Expect from Commercial AC and Residential AC

When exploring the differences between commercial AC and residential AC, consider the following:

  • Residential AC is Simpler to Install: Easier to install, residential AC comes with standard central units that are connected to ducts. Residential AC usually keeps the condenser outdoors and its evaporator inside the building in a basement or garage.
  • Residential AC Maintenance is Inexpensive: As residential AC serves to provide air conditioning on a much smaller scale, the rates for performing residential AC maintenance are significantly lower in comparison to commercial AC.
  • Commercial AC is More Effective for Businesses: While the effectiveness of commercial AC for businesses depends on the size of a space, any significant office building would want to have commercial AC installed.
  • Commercial AC Requires Complex Zoning: While it may be better for businesses, commercial AC cannot be installed without adhering to certain complex zoning laws.
  • Commercial AC Uses Extensive Draining: The complexity of commercial AC requires it to use an extensive draining system. While residential AC uses a condensate pan, commercial AC needs several pans with drainage pipes that ensure the water doesn’t overflow the pans during the evaporation phase.

While there are various pros and cons to each form of air conditioning, making the choice between the two really comes down to what your air conditioning needs are. While you may automatically choose residential AC for your home, you may be considering commercial AC for your business.

However, this needn’t be the case. If your business has only a few employees, perhaps residential AC would better suit your situation. Ready to learn more about commercial AC and residential AC? Call us today at 408-295-2182.

What’s the Best Type of New AC Compressor?

When you need to replace the compressor in your air conditioner unit, you might wonder what kind you should choose. You want to select a compressor that will perform well and keep your building cool

However, you also may want it to lower your utility bills and not make a lot of noise while it functions. You can decide what type of air compressor is best for your building by learning about the available models.

Centrifugal Air Compressor

A centrifugal air compressor uses centrifugal force to move around refrigerant in the unit. It uses this force to pull in the coolant before rapidly spinning it with the impeller in order to compress it.

A centrifugal compressor is ideal for using in extra large HVAC systems. If your building uses a large air conditioner unit, you may decide that a centrifugal air compressor is right for your needs.

Rotary Air Compressor

A rotary air compressor can be the perfect choice if you are concerned about noise. When you want a quiet air compressor, the rotary model may suit you well because it:

  • Is small and quiet
  • Contains a shaft with several blades attached to it
  • Pushes coolant through the cylinder while compressing it at the same time


If you prefer your air conditioner function as quietly as possible, you could reduce the noise level without sacrificing the service of the unit by installing a rotary air compressor in it.

Screw Air Compressor

The screw air compressor has a reputation for being reliable and efficient. It is typically used in large buildings where substantial amounts of air need to be continuously cooled.

The screw air compressor has two large helical rotors that move the air in the unit from one end to the other. When the air moves through the compressor, the space gets smaller and the air gets compressed.

Reciprocating Air Compressor

The reciprocating air compressor is perhaps the most popular model available today. It has a piston that moves air up and down inside of the unit’s cylinder.

As it moves the air down, it creates a vacuum that sucks in refrigerant. As the air moves up, the gas compresses and moves into the condenser.

These models are the most common types of air compressors on the market. You can find out more about your choices by calling 408-295-2182 today.
