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 do I Determine Whether an HVAC Retrofit is Right for my Commercial Building?

Are you paying huge electricity bills every month for your business? If you have an older HVAC system that is driving your energy bills, you might be considering an upgrade. But what if your current financial status doesn’t allow you to install a new air conditioning unit? Does it mean that you will continue to foot large electricity bills for your commercial facility?

Also, regardless of how well you maintain your air conditioning unit, it will need to be a replacement at some point. Most of the HVAC systems have a life-span of 15-30 years. The functional life of these units is determined by the brand and style of the equipment. When your HVAC’s useful life ends, you will need to choose between replacing the entire system or retrofitting your HVAC unit.

What is HVAC retrofit?

HVAC retrofits allow you to utilize higher efficiency equipment and to add features to your existing HVAC unit to increase safety, comfort, durability, and efficiency. HVAC retrofitting helps to solve various air conditioning problems such as fluctuating temperatures, poor air movement, and changes in moisture levels. Sometimes, making small changes such as adding economizers can sealing ductwork in your air conditioning unit can change its performance significantly.

How do you know it’s time for HVAC retrofit?

Most of the HVAC retrofit projects arise from the need to increase efficiency, comfort, and safety of the air conditioning unit. Besides, you may need to retrofit your HVAC unit if:

• It is more than ten years old
• The electricity bills keep going up without any logical explanation
• You spend more money repairing your old HVAC system
• You experience changes in the indoor air quality

An old HVAC unit will require frequent repairs, lose efficiency, and also compromise comfort with time. When you get to this point, you may need to retrofit your air conditioning unit to restore its performance.

Common HVAC retrofit upgrades

There are various types of HVAC units, and they require different retrofit upgrades. Some of the equipment that are best candidates for retrofit upgrades include chillers, boilers, and package rooftop units. Retrofit upgrade services offered by certified HVAC contractors include:

• Sealing and replacement of ductwork
• Installation of airside economizer
• Replacing old compressors with new generation screw compressors
• Fitting carbon dioxide sensors
• Fitting supply fab speed controls
• Fitting smart temperature and humidity controls

When it’s Time to Upgrade Your HVAC Unit

You may have an older HVAC unit that’s causing you some problems. Older heating/cooling appliances can be tricky when determining what’s wrong with them. Pinpointing the issue is one thing. Deciding if you should repair or just replace the unit is a little more difficult.

If you are wondering if you need to replace your appliance, then check out the following signs to determine if an upgrade is in order.

Signs Your HVAC Unit Needs Upgrading

Higher bills- If you notice your utility bills are higher than usual, your HVAC unit may be using up more energy than it really should. Older appliances tend to need more power to run as they start to wear out.

Too much maintenance- If the repair costs of the unit far exceed the price you paid for it, upgrade your appliance. A new one would end up saving you money in the long run.

Noises- You may notice some loud, scary sounds coming from the unit. Often, parts loosen up or wear out. In older appliances, it may be hard to find replacement parts, or they may be costly to swap out.

Runs longer or there’s no heat/ cold air- The unit runs a lot longer than normal to warm up or cool down your home. Or, you may notice that it’s not kicking out heat or cool air at all. Ineffective parts can cause the appliance to work harder to get the job done. Or, you may have parts that just aren’t working.

Bad Odors- You might start noticing unusual odors coming from your unit when it’s trying to run. Parts, like motors, often smell bad when they’re going out. That smell will only get worse.
Age- Older units are doomed to go out eventually. If you find that yours has been around for more than 15 years or so, it’s probably time to upgrade your HVAC unit. It’s best to swap it out before your older heating appliance goes out.

Upgrading your heating/cooling device will bring you far more benefits in the long run. You’ll see your bills, as well as your repair costs, go down. You’ll also improve the quality of the air you’re breathing in, while eliminating respiratory problems you might have.

Why You Should Replace AC Ducts

When you are outside, you can breathe fresh air from all directions. In a building, you might receive the majority of your air from your air conditioning (AC) ducts. Learn why you should replace AC ducts.

Most air is a combination of many different elements, including oxygen. The dirtiest air is filled with germs, dust, smoke and other airborne contaminants. Some diseases are spread through the air.

When your workers have the freshest air with the highest percentages of oxygen, they are the most productive. They can concentrate and complete tasks faster. Here are some of the reasons for replacing AC duct work:

  • Fresh Air
  • Reduce Airborne Contaminants
  • Prevent Diseases
  • Indoor Air Quality

Do you know what is breeding in your air duct work?

Replace Air Ducts

When an athlete goes to the sideline, he gets oxygen to reinvigorate him. Fresh air can increase your workers’ productivity. They can process information faster and complete their tasks on time.

Do you want your workers to be coughing into their keyboards? This prevents them from completing their assignments. It also spreads germs and increases the chances that others will get sick too.

More sick time will lead to fewer productive hours. Airborne diseases can cause simple fatigue or lead to more serious lung problems. This is especially true during the flu season.

There are many other types of contaminants that simply make breathing more difficult. Dust can clog up the lungs. Coal mine workers eventually get “black lung” due to long periods of exposure to airborne contaminants. How do the lungs of your employees look?

As a building owner, you are not only responsible for your employees, but also guests and vendors. What do they say about your Indoor Air Quality behind your back? Do they rue visiting your establishment or leave with a hacking cough?

If you care about promoting an image of excellence, does this not extend to having superior Indoor Air Quality also? Rats, squirrels, bats and birds nest inside your air ducts. Vermin leave all sort of waste material that are then recycled into the air, you breathe.

Replacing your AC ducts can help all people breathe easier, avoid airborne diseases and work more productively. Are you convinced that your AC ducts need cleaning? If so, call us today at 408-295-2182

Can You Just Replace an AC Compressor Instead of The Whole Thing?

The HVAC system of your business is a critical component of your building and its function is vital to the overall health and ability of your business to function, whether you are running a small office building or a large industrial complex. Keeping the air temperatures regulated and airflow moving steadily can impact your bottom line.

Often, as the HVAC unit or units for your business age, they show symptoms of failure before complete breakdown. Symptoms such as failure to produce cool air can be tracked to a number of smaller issues, such as a coolant leak or a line blockage, but a thorough inspection by an HVAC professional may also uncover major issues such as a compressor failure.

In the case of a compressor failure, you need to decide whether your business will best be served by replacing the compressor or by replacing the entire AC unit.

Replace the Compressor or Replace the AC Unit?

  • Consider replacing just the compressor if the existing AC unit and component parts are still under warranty. In this instance, the new compressor should not cost you anything but you will still need to pay for the labor to do the job. Make sure to get a quote on the labor, time, and materials as replacing a compressor can be a challenging and time-intensive job.
  • Consider replacing the AC unit if the system is past warranty. While you could opt for replacing just the compressor in this case, bear in mind that the cost of a new compressor, as well as the cost for labor and materials, may be close in range to the cost of installing a new AC unit.
  • Consider as well that a new compressor may only come with a limited warranty, up to
    1-2 years, and that you may find yourself back in the same situation in a short amount of time, facing the same issue without the benefit and security of a warranty to offset the cost.

Dealing with the advanced and technical needs of your HVAC system can be daunting, especially if your business is impacted by changes in temperature and loss of cooling due to AC problems. Let us solve your AC problems so you can focus on what matters most: the success of your business. We can help, call now 408-295-2182

How Does an Industrial Air Handler Work?

The industrial air handler is an integral part of most industrial HVAC systems. Also known as an air handling unit, this device is responsible for the circulation and regulation of air through the HVAC system. Particularly because of its importance to the overall system, you may be curious about how your HVAC system’s air handler works. Before getting to know the process, it can be helpful for you to learn the terminology and types of air handlers so that you can better understand the unit that you use in your facility.

Your facility’s HVAC system most likely has a large outdoor air handling unit. These are commonly referred to as packaged units (PUs) or, when located on the roof, rooftop units (RTUs). Both of these are also called makeup air units (MAUs), as they only condition air from outside the facility rather than recirculating the air from inside. Air handlers that recirculate indoor air are known as terminal units. These are generally smaller and are only used in localized areas.

The Air Conditioning Process

The easiest way to explore how your air handler works is by examining the route that air takes through the various components of the whole unit. For most larger systems, this process is as follows:

  • Return fans bring air in from the return duct through air filters to prevent dust and other impurities from traveling through the system.
  • Heating and cooling elements, which may involve direct or indirect heat exchange methods, then condition the air to the desired temperature.
  • A humidifier may be present in colder areas to help prevent heating units from drying the air too much during the conditioning process.
  • In temperate climates, air is often moved to a mixing chamber, where return and exhaust air may be mixed to more accurately reach the desired temperature.
  • Supply fans will then blow the air back into the facility through the supply duct.

 

Not all industrial air handlers are made the same. Depending on the size, type, and other factors of your facility’s air handling unit, you may notice different or additional components. You can always talk to an expert if you have additional questions about the inner workings of your industrial air handling unit.
