How to Tell Your Commercial HVAC System Needs Repair

Monday, January 5th, 2015

If your commercial HVAC system breaks down completely, there’s no doubt you’ll hear about it. Complaints from customers, clients, employees, and/or tenants are almost guaranteed, particularly in the middle of summer, or during a cold winter’s night. But most likely, you’d rather avoid this situation and catch repair needs before a heating breakdown puts your business out of commission for a spell.

But how can you tell when it’s time to call for commercial HVAC repair?

At DuAll Heating & Cooling, we want to make sure that your commercial property isn’t left in the cold (or heat). Here are a few things you should check on to tell whether you need to schedule repairs.

  • Noises from the Ducts or the Unit: Chances are, you don’t hang around your commercial HVAC unit too often (since many of these are located on the roof of a building). But if you do happen to hear a strange noise (even a small one) from up above, from the boiler unit, or from inside of the ductwork, it could mean trouble with a fan, circulator pump, compressor, or any other vital heating/air conditioning component. This could lead to further trouble later on, which is why it’s important to call for repairs right away.
  • Reduced Heating or Cooling: To some business owners or managers, it may be a given to call for repairs when heating or cooling is suddenly reduced due to the nature of their business. But others suspect that the trouble will improve, or that they can wait a bit longer to call. However, the trouble can worsen as the parts become overworked attempting to get your building to the proper temperature.
  • High Utility Bills: High utilities may be a sign of parts that are working overtime to heat or cool the property, which means something within the unit is not quite right.

A final way to determine that your system is in need of repair is if your technician tells you so during a standard maintenance. At DuAll Heating & Cooling, we recommend you schedule maintenance twice a year with a commercial specialist to avoid sudden breakdowns.

Air Conditioning Question: What is a Rooftop Unit?

Monday, August 27th, 2012

Rooftop units tend to be used in commercial buildings for both air conditioning and heating purposes.  As light commercial HVAC specialists in Bolingbrook, DuAll Heating & Cooling works with rooftop units for a variety of businesses in the area, so call us today if you are interested in installation or repair.

Rooftop units are specially designed heating and air conditioning systems that are placed on the rooftops of commercial structures.  They both cool and heat larger buildings such as retail storefronts, office spaces, strip malls, and even warehouses.  Rooftop units can include a wide selection of special features such as high-end filtration systems, humidifiers and dehumidifiers, and even the option of solar panels for a much higher level of energy-efficiency.

Commercial rooftop air conditioning and heating units are usually housed in one cabinet that conditions the cooled or heated air.  An air handler then pushes that air through an intricate series of ducts which are usually run between floors, or behind walls.  As the air moves at a uniform speed and is well-balanced throughout the ducts, each room with a vent will receive the proper amount of air that has been preset by the HVAC thermostat.

Rooftop units are designed to be dependable, working all year long to make the various indoor workspaces comfortable to be in.   They can provide cooled and heated air with one single unit, but there are also separate rooftop AC and rooftop heating units that are then connected to the same ventilation and ductwork system.

DuAll Heating & Cooling is a light commercial HVAC company in Bolingbrook that understands the intricacies of rooftop units and can help you through rooftop AC installation, repair or maintenance.  Contact DuAll Heating and Cooling today!
