Simple Steps to Prep Your Commercial HVAC System for Cooling Season

A well-maintained HVAC system can provide reliable cooling during the cooling season, helping to reduce energy bills and improve air quality for occupants. Proper maintenance includes regular filter changes, cleaning of cooling coils and drain pans, sealing of ducts, and regular inspection by an HVAC professional. Additionally, it is important to keep the system free from dust and other debris. Following these steps can help ensure a comfortable cooling season for all.

What is Cooling Season?

Cooling season in HVAC refers to the time of year when air conditioning is necessary for comfort and health. In many parts of the world, this generally lasts from May through September, although regional climates may cause it to begin or end earlier or later. During cooling season, an HVAC system circulates cool air throughout the home, office, or other building to keep the indoor environment comfortable. The temperatures used vary by region and comfort level.

Keys for Comfortable and Efficient Cooling

Replacing your HVAC coils is essential before cooling season because worn-out or damaged coils can lead to higher energy bills, poor indoor air quality, and inadequate cooling performance.

Check Coils for Leaks prior to Startup

Freeze Damaged HVAC Coil with Split Return Bends

Although not typically used during winter, some cooling coils may have split tubes and freeze damage due to exposure to freezing temps over winter. It’s important to check all coils for leaks several months before cooling season. This allows time to order and install the coils before they are needed to cool a building. Newer models of coils are more efficient than ever before, so replacing them can help you save money on your energy bills.

Cleaning Coils and Drain Pans before Cooling Season

Cleaning your HVAC coils and drain pans is essential for proper functioning during cooling season. Dirty coils can cause the system to work harder, which leads to higher energy costs and reduced cooling performance. Cleaning the coils also helps reduce the amount of dust, dirt, and other debris that can accumulate in the system over time. It’s important to clear out any debris that might be obscuring the coils, as this can prevent them from transferring heat effectively.

In addition to cleaning the coils, it’s also important to clean the drain pans and lines. If there is a buildup of dirt or other debris in these areas, it can impede the flow of water and lead to water damage. Regularly cleaning these areas can help ensure that your HVAC system is functioning optimally during cooling season.

Types of Cooling HVAC Coils

Chilled Water Coils

Known as hydronic cooling coils, chilled water coils are a type of heat exchanger used to reduce temperatures and humidity from air streams. Air passes through the fins while either water or an ethylene/propylene glycol solution circulates in the tubes for superior cooling capabilities. The flow of water and air generally move in opposite directions which maximizes heat transfer; this arrangement is known as counter-flow heat exchanger technology.

Direct Expansion (DX) Coils / Evaporator Coils

DX (Direct Expansion) coils, also called evaporator coils, are one of the most common types of coils used for cooling in HVAC systems. Evaporator coils remove heat and moisture from the air, cooling it in the process. The coils contain refrigerant that absorbs heat from the air as it passes across them, lowering its temperature.

Evaporator coils are available in an assortment of sizes, designs and capacities depending on the type of installation required, cooling capacity needed, and manufacturer. To increase the coil’s performance without changing length or width while keeping additional rows in place; more copper/aluminum tubing is added bringing you even closer to your optimal result!

Condenser Coils

A condenser coil is an important part of any cooling system. It takes heat away from the refrigerant and helps it turn back into a liquid. As air passes over the top of the coil, heat is taken away. A separate part of the coil helps make sure that the refrigerant changes back from gas to liquid. This all helps the cooling system run smoothly.

Why do Coils Fail?

Coils fail for a number of reasons.

These include:

// Vibration // Corrosion

// Excessive fan cycling

// Low load cycling // Physical damage

Fin/Tube coils are naturally susceptible to galvanic copper to aluminum corrosion that significantly reduces fin performance over time, and can also sacrifice the aluminum fin material in seacoast environments. Copper elbows and tubes also can corrode, pit, and crack over time. Thus, a coil mean time to failure can range from 5-10yrs, and preferably 15-20 years or more, if robust.

Microchannel coils, manufactured by others can fail due to the same reasons listed above. In many OEM systems, these coils are automotive style and use thin tube walls, yet are susceptible to the worst of operating conditions, vibration, and sea coast effects. Microchannel coils are the future of chiller condenser coils, but must take the same abuse, wear and tear.

Why Evapco Alcoil?

Evapco Alcoil is an all-aluminum microchannel coil, designed for high efficiency, with fins integrally brazed to the tubes, and tubes integrally brazed to the headers. Evapco Alcoil, however, is a robust industrial constructed coil with thicker tubes and thicker headers. It is the latest generation of high-performance condenser coil with vertical tubes (not horizontal) to reduce standing water on the coil, reduce thermal stresses and provide features intended for longer life operation.

How is a Evapco MicroChannel Replacement Coil Different from an OEM MicroChannel Coil?

// Non-Automotive, industrial design

// 25-30% Thicker tube walls

// Epoxy Coating for superior corrosion protection

// Lower Refrigerant Pressure drop for improved operation and oil return

// Built-in Mini-receiver (in lower header) to make it easier to charge

// Side Flange for drop in/slide in installation

// 5-Year Warranty

How to Tell When Your HVAC System Needs to have the Coils Replaced

by Caitlin B. | Feb 23, 2020 | Coils

Don’t let them fail! Here’s your HVAC coil replacement guide

The coils in an HVAC system are some of the most important parts of your air handling system, which is why a proper HVAC coil replacement is essential to keeping that system running. The HVAC coil is an essential component that your system just can’t run without. If you suffer from an HVAC coil failure and your coil springs a leak—or worse, it ruptures—you have a huge problem on your hands. Damaged coils can cause massive losses of product, degrade air quality, and lead to extensive water damage.

So don’t let your coil break, and make sure to stay as up-to-date as possible on your repairs. A good inspection and repair schedule can extend the life of your HVAC coils by many years. But the truth of the matter is that HVAC coils have a life expectancy and even with the best care eventually require replacement.

So how can you tell when you need to repair vs replace? Look for the signs listed below for a rough idea of when you should have your HVAC coils replaced.

Signs That Show Your System Needs HVAC Coil Replacement

If you take good care of your HVAC coils, they will last a long time. But eventually, everyone will need an HVAC coil replacement. Here are a few signs that you should replace HVAC coils instead of spending your money on the HVAC coil leak repair cost.

Is there oil residue in the condensate drain pan tray? If there is a leak in your system, the fluid or refrigerant may be leaking out, which causes a drop in performance. The refrigerant looks like a dark oil, and if you see it in the tray, then there’s probably a leak. A leaking HVAC coil should be replaced before it causes further damage.

Do you need to replace fluids or refrigerant often? If you feel like your system is always low on fluid or refrigerant and you find yourself replacing it often, it might mean that you have a leak. A perfect system has no leaks and should rarely need replacement. Most systems aren’t perfect, but you still shouldn’t need to add fluids or refrigerants every few weeks. If you find yourself performing maintenance more than you should have to, you may have a leak. Check for a leak or call a professional to do it for you.

Can you spot an actual leak? Sometimes a leak in the coil will be obvious (like a freeze-induced rupture), but sometimes it will not be. Just like a bicycle tire, you can find a leak in an HVAC coil by smearing soap on a suspicious spot and watching for tiny bubbles. If you do find a leak, don’t let the air conditioner coil replacement cost prevent you from replacing the coil before it gets out of hand.

If you find a leak in your system, call a professional. Not every leaky coil needs to be replaced: some of them can be repaired with a leak seal treatment or by brazing the hole. A professional can help you make the best decision for your air handling system and your building as a whole. Give Cooney Coil a call or get in touch today to find out how we can help.

5 Ways to Prepare for Heating Season

by Caitlin B. | Sep 30, 2019 | Coils

The summer has come and gone, is your HVAC system ready for heating season?

Winter is coming. Get ready with our 5 quick tips to prepare your facility.

Replace Filters

Dirty filters cause a reduction in airflow. This makes your HVAC unit work harder leading to higher operating costs. Replacing your filters on a PM schedule will help keep your coils free from debris, making them more efficient.

Coil Leak Test

Before starting up a coil this season, test it for leaks. Some leaks may be easy to spot, like a split from a freeze-damaged coil. Others may be too small to see. There are several tests you can perform on a coil to test for leaks. The easiest test is the soap test:

Apply soap solution
Watch for bubbles

The formation of bubbles indicates a leak. Address any leaks before they get out of hand and replace coils when necessary to ensure reliability throughout the colder months.

Test Isolation and Control Valves

Valves are used to isolate areas of piping, control both fluid and steam flow, and regulate pressures. Systems are designed to operate at certain parameters. If a valve fails or leaks, those limits could exceed design setpoints for equipment in the system. When a control valve is not operating properly, the equipment it serves (coils, heat exchangers, etc.) will not perform as intended. As heating season nears, you should double-check the operation of all valves in the system.

Vent Air from Coils

Drain Port HVAC COil

Air is the world’s best insulator, which is why double-pane windows have a thin layer of air in between the two panes of glass. If there is air inside of a coil or heat exchanger, the heat will not transfer at the same rate. This could result in cold spots, air stratification and/or drop in efficiency.

To remove all air from a coil, make sure to remove the plug from the air vent (typically found near the top of the header of the leaving fluid side) and fill the coil slowly from the lower connection. This will force the air up and out of the air vent.

Replace Broken/Damaged Coils

If your coils are broken or damaged replace them before winter is upon us. Swapping out old inefficient coils will ensure your facility stays warm all winter. When ordering new coils, add Freeze Block Technology to protect your coils from potential freeze damage. You’ll have peace all winter long, knowing your coils are guaranteed by the industry’s best warranty – 30-month protection from freeze damage. Make it a Smart Coil and receive a warning when a freezing event occurs and extend your warranty to 48-months.
