Our searchable database of stock coils contains of over 200,000 hot water coils and stock booster coils, and includes part numbers and prices. We recently added performance data to stock coil descriptions to make it easier for HVAC professionals to select and purchase new and replacement coils.

The stock coil database allows you to run searches based on specifications, including: Tube Diameter, Casing Type, Rows, Fin Height, Fin Length, Fins Per Inch and Connection Size. The newly added performance data includes: Capacity, Air Flow Rate, Entering Air Temp, Leaving Air Temp, Air Pressure Drop, Entering Fluid Temperature, Leaving Fluid Temperature and Fluid Pressure Drop.

After you narrow down options based on specifications, you can view performance data to find the right fit for your HVAC system. For example, if 36,000 BTUs are required for an HVAC system, you can review the Capacity data to find a stock coil with the right tonnage. Or if you have a concern about water or fluid pressure drop, you can see how a specific hot water coil will do under standard conditions.

Emergent Coils offers a wide range of stock coils with prices starting at $150 to $500, depending on the type and size of coil needed. Stock coils are typically shipped within three to five business days.

We also offer quick build options, so you can have coils within two days.

5 Ways to Lower your Commercial Heating and Cooling Costs

Posted By Tommy Thompson On 08/28/2017 at 12:16PM

The cost of heating and cooling commercial buildings is a major expense. According to the U.S. Department of Energy, commercial buildings represent just under one-fifth of U.S. energy consumption, with office space, retail space, and educational facilities representing about half of commercial sector energy consumption. In an average commercial building, as much as 30% of the energy and cost that goes into powering heating, ventilation and air conditioning (HVAC) systems are wasted.

To lower the operating costs associated with heating and cooling your commercial building, reducing energy waste should be at the top of your list. Reducing waste can be as simple as routine maintenance. It could also mean investing in new energy-efficient heating and cooling solutions for your commercial building. Here are 5 ways to lower your heating and cooling costs: • Change your HVAC filters on a regular basis. Dirty filters make it harder for air to flow through the system, which requires more energy. Dirty filters also reduce indoor air quality and increase commercial HVAC maintenance issues and costs. This simple step can reduce waste by between 5-10%.

• Use programmable thermostats. Businesses can set thermostats to coincide with business/non-business hours to reduce energy waste. By automating these changes, people will remain comfortable during work hours. During non-business hours, thermostats can be set at higher temperatures in warmer months and lower temperatures in colder months when spaces are not in use, reducing energy consumption and lowering costs.

• Schedule routine HVAC maintenance. Routinely check HVAC systems for leaks, cracks and other signs of wear and tear that reduce heating and cooling capabilities. Damaged coils, improper seals and dirty filters are just a few of the things to look for. While it’s tempting to come up with low-cost temporary solutions, like patching leaking HVAC coils, performance goes down and the temporary fix might lead to problems with other heating and cooling components. If you have a leaking chilled water coil, hot water coil, steam coil or refrigerant coil contact us for a quote.

• Upgrade or replace HVAC equipment. HVAC systems wear out over time. Rather than putting more money into outdated, inefficient systems, upgrade elements or replace HVAC systems with energy efficient models. Consider buying ENERGY STAR-certified products, including furnaces, boilers, air conditioners and heat pumps. The increase in efficiency will offset the investment in new equipment.

• Look into tax incentives for upgrading equipment. Tax incentives may help offset the costs for energy efficiency upgrades in commercial buildings. To learn more about the tax incentives available under The Energy Policy Act of 2005 (EPACT) and The Emergency Economic Stabilization Act of 2008 extended provisions in EPACT, visit

4 Tips for Improving Energy Efficiency in Commercial Buildings

Posted By Tommy Thompson On 05/21/2017 at 09:37PM

As I’ve discussed before, you can improve the energy efficiency and performance of your commercial HVAC system by doing regular maintenance (cleaning coils and replacing them when they start to fail, etc.). But improving energy efficiency in commercial buildings goes beyond HVAC systems.

According to the U.S. Department of Energy, lighting represents the largest source of electricity consumption in commercial buildings, costing an estimated $38 billion per year. The National Renewable Energy Lab is working on a way to help commercial buildings save on lighting and ventilation costs by improving the accuracy of motion detection.

In the meantime, here are 4 Tips for improving energy efficiency. Don’t forget to share this information with tenants and others in your buildings to improve overall energy efficiency. • Rethink your lighting. o Install occupancy sensors, which can reduce lighting costs by up to 40%. o If sensors aren’t an option, remove excess lighting not necessary for security and safety. Turn off lights in unoccupied areas and after hours. o Replace incandescent bulbs with compact fluorescents, which can last up to 9 times longer. o Upgrade fluorescent lighting fixtures to high-efficiency equipment. o Replace incandescent lights in exit signs with LED fixtures to reduce costs by up to 95%. • Use sun-blocking solutions on windows. o Close the blinds when direct sunlight is heating up the room, use solar shade screens, or add sun-control film to windows. This reduces HVAC usage and lowers energy consumption. • Power down office equipment when not in use. o Energy costs can be cut by approximately 40% by using sleep-mode when computers, monitors, printers, and copiers are not in use. Turning off office equipment after hours or unplugging unused equipment reduces costs even more. o Automate the process using “smart” power strips, which sense the presence or absence of office workers and turn the attached equipment on or off accordingly. • Buy energy-efficient products. o ENERGY STAR certified equipment, including computers, monitors, and printers, are more energy efficient than other products, saving you money on utility bills, and helping protect the environment. For more tips on increasing your energy efficiency, visit DC’s Department of Energy & Environment website. Improving energy efficiency lowers overall operating costs and saves valuable resources.

Making sure your commercial HVAC system is ready for summer

Posted By Tommy Thompson On 04/01/2017 at 09:51PM

Now is a great time to make sure your commercial HVAC system is ready to handle spring and summer cooling. Evaluating your evaporator coil and condenser coils is part of the process.

The evaporator and condenser coils inside a central air conditioner or heat pump facilitate the heat exchange process, which is the basis of refrigerated cooling and, in the case of heat pumps, heating. Refrigerant circulates on a continuous loop between the evaporator coil and condenser coil.

As you probably know, the evaporator coil is located inside or near the air handler where the blower fan is. The condenser coil is located outside in the condenser unit, which also contains the compressor, a fan and copper tubing, as well as valves and switches. Condenser coils come in a variety of shapes, but for most central air conditioning systems, the condenser coil wraps around the sides of the outdoor condenser unit. The evaporator coil works with your heating system in the winter and your cooling system in the summer. Evaporator coils are made from copper, steel or aluminum because these metals conduct heat easily. The evaporate coil operates with the air conditioner or heat pump to condition and cool indoor air that flows over it by removing moisture and heat. In winter, the heat pump pulls air in from the outside and runs the air over the evaporator coil. The colder air is warmed by the evaporator coil and then pumped through the ductwork to heat the building. Even if the air outside the building is below freezing, the HVAC system is able to pull some heat from it. The first sign there may be a problem with the condenser coil is when the temperature of the cooled air is warmer than the thermostat setting. Check the amount of refrigerant in the system to make sure there is enough coolant. If the coolant level is OK, it might be time to replace the condenser coil. Check your local guidelines to learn about the proper disposal of old condenser coils. Also check for leaks in your evaporator coils if the refrigerant level is low. Corrosion from building materials, furniture and common cleaning solutions that produce fumes called volatile organic compounds (VOCs) can cause the evaporator coils to leak. Contact our coil experts at 1-855-Coil-Now or if your commercial HVAC system needs new or replacement condenser and evaporator coils.
