Common Repair Problems with Commercial HVAC Systems

Friday, June 13th, 2014

The equipment for light commercial HVAC systems is more durable and sturdier than those found in homes… but that doesn’t mean they will experience any fewer repair issues. Commercial air conditioners, heaters, and packaged units must undergo much more stress than residential comfort systems, and that means they will need occasional service from trained experts.

Whenever you experience issues with your business’ heating or cooling system, contact DuAll Heating & Cooling for the service that will restore your workplace to the level of comfort your employees need and your customers/clients expect. We handle light commercial HVAC repair in Naperville, IL.

Here are a few common problems with commercial HVAC systems that our technicians encounter on the job:

Damage to the fan

The majority of commercial comfort systems are rooftop packaged units: all the components are housed in a single cabinet kept on the roof. Although the roof offers a large amount of isolation and therefore protection for the unit, it also exposes it to the elements. Debris can sometimes infiltrate the cabinet and cause damage to the large fans necessary for the heat exchange cycle. Loss of the fans will affect heating and cooling within the building and will require professional repairs.

Thermostat troubles

Even light commercial HVAC systems can use a complex series of thermostats and controls, far more intricate than those found in homes. Businesses frequently have zone control systems set up to allow different temperatures in different parts of the workplace, and errors with the thermostats can cause zones to lose conditioned air. It takes experienced commercial repair technicians to track down and figure out thermostat problems.

Insufficient heating/cooling

If air is blowing out of the vents, but it isn’t the expected temperature (room temperature instead of cooling or heating), you’ll soon start to hear complaints about it. The trouble may be in the thermostat, but it’s more likely a problem within the rooftop unit, such as a leak in refrigerant. If the rooftop unit is a heat pump, the problem could be a broken reversing valve, which will prevent the system changing form one mode to another.

The right time to call for commercial HVAC repair in Naperville, IL is immediately.  Our NATE-certified light commercial HVAC specialists are ready 24 hours a day to help keep your business at the right temperature.

As soon as you notice a change in temperature, hear loud sounds from the ductwork, or detect a drop in airflow from the vents, contact DuAll Heating & Cooling.

3 Unique Qualities of Commercial Air Conditioning Systems

Friday, May 30th, 2014

The commercial world has different requirements for air conditioning (and heating) than the residential world. Businesses must remain appropriately cooled down to keep customers/clients happy and employees content and productive. These different needs for businesses mean that their HVAC systems are unlike those found in homes. And that means they need installation, repair, and maintenance work from technicians specifically trained on commercial systems.

For light commercial air conditioning in Romeoville, IL that will keep your workspace comfortable through this summer and many summers in the future, call DuAll Heating & Cooling. With the amount of stress that your AC may experience this season, you need to have technicians on which you can count… any time of the day or night.

3 qualities that make commercial ACs different

  1. Packaged unit design: The majority of commercial HVAC systems are packaged systems, unlike the split systems that most homes use. A split system has an outdoor condenser cabinet and an indoor evaporator unit. Commercial systems have both the condenser and the evaporator—along with the compressor and fans—placed in a single cabinet, which is usually located on the roof. This design and placement saves space for a business, makes the HVAC cabinet easier for a technician to repair without intruding onto the workspace, and helps reduce the noise level from the system. Some package units are also heat pumps, so they can provide heating as well as cooling.
  2. Size: There is simply no comparison between the size of a commercial system and a residential one. Even a large mansion won’t require the amount of cooling power that a small business space needs. This isn’t only an issue of space, but of the amount of people who need cooling. More cooling is required to accommodate more people, but also to overcome the amount of heat that additional people generate. Commercial air conditioners are vast compared to home systems, and have special requirements with which technicians must be familiar.
  3. Modular design: Commercial air conditioners are designed as separate modules, usually in 10-ton, 12-ton, 15-ton, and 25-ton units. This makes it easier to construct and move a large and powerful AC system. The main advantage of modular design, however, is that it allows a company to expand without needing to replace the entire air conditioning system. Technicians can increase the cooling load with the addition of a new module of the appropriate size. For businesses that intend to expand, this is a significant benefit.

Never trust your company’s comfort to amateurs or technicians without experience on commercial air conditioning in Romeoville, IL.

3 Advantages of Roof-Mounted HVAC Commercial Units

Friday, March 28th, 2014

You need to have an effective and efficient HVAC system keeping your business comfortable throughout the year, whether it’s warmth during the winter, refreshing cool during the summer, or all the mixtures of temperatures in the seasons between.

One of the most popular ways to provide heating and cooling for businesses is a roof-top HVAC unit. There are a number of reasons these rooftop HVAC systems are so popular. We’ll look at three.

When you’re ready for commercial HVAC installation in Romeoville, IL, call on DuAll Heating & Cooling. Many companies in Romeoville and the surrounding towns have placed their trust in our services, and we’ve delivered them the comfort they needed. We can do the same quality work for you.

3 Reasons to Install Rooftop Package Units for Your Business

  • Space-saving: Unless for some reason you like to do business on the roof of your building, the roof is the best place to install an HVAC system as large as the one necessary to condition a significant space. Since all the components found in larger commercial HVAC units are put into one self-contained cabinet, the rooftop system won’t even take up that much room at the top of your business.
  • Cooling and heating in one (if you want it): Rooftop units are often configured to contain all the heating and cooling needs for a building, so you won’t need to have separate systems. This is convenient for you, and it also makes it easier for technicians to repair the unit. However, you don’t need to have heating installed in your rooftop unit; installers can configure them for air conditioning only if you wish.
  • Pre-assembled and easy to install: Putting in a roof-mounted HVAC system is a simple job for installers, since the units come as complete packages with all their components already in place. This means that having new units installed will pose no major interruption to your business.

Roof-Mounted Units Require Regular Maintenance

There is one drawback to a rooftop HVAC unit, and that is that it receives exposure to the elements, such as rain, snow, and occasional hail. Manufacturers build these units for durability, but they aren’t indestructible. To get the maximum life from your commercial rooftop HVAC system, make sure you schedule annual maintenance from specialists.
