HVAC Cleaning Checklist

As the seasons shift from Winter to Summer, it is an ideal time to take advantage of the milder temperatures by taking a look at the performance of your HVAC systems. Setting aside time to inspect your HVAC system is imperative for the HVAC’s performance level to operate at maximum efficiency. This time of year is also a smart time to install an industrial HVAC system for your establishment!

Here is a brief overview of the components that help your HVAC system run, understanding these components and their functions makes annual maintenance that much easier to complete! An HVAC system is an explosion-proof unit consisting of 9 essential components which include an Air Return, Filter, Exhaust Outlets, Ducts, Electrical Elements, Outdoor Unit, Compressor, Coils, and Blower. These components are responsible for functioning together as a team to regulate the heating, cooling, and ventilation of your home or establishment. Whether you live in a single-family home in Baton Rouge, a lakeside mansion near Hammond, or work in any kind of industrial or commercial building, you will still need a high-quality HVAC system with an explosion-proof air conditioner to regulate intense temperatures in the deep South.

Inside Components of Condensing Unit

Here is your efficient, simple, and quick HVAC maintenance check-list:

1. Filters:

We hear this word all the time when our cars or other appliances require cleaning, and your HVAC system is no exception. The purpose of the filter on an industrial HVAC system is to filtrate the air from pollutants like mold spores, dust, or any other toxic particles. Keeping your air clean is paramount for your health and the health of anyone in your establishment. It is recommended to check these filters on a quarterly basis (around 4 times a year) if your unit operates in an office building or a relatively clean environment. Alternatively, if your HVAC system operates in a higher-trafficked environment, like a restaurant or auto shop, then it is best to clean/replace your filter more frequently.

2. Clean the Outside Area:

The outdoor container housing your HVAC unit should be clean and free of debris because the debris can clog vents and block or reduce airflow. Remove any grass, mud, leaves, stickers, litter, or other distracting materials from your vents and coils. While you’re cleaning those coils, take a look at the coil’s integrity and straighten out any bent sections. If you’re cleaning a cabinet HVAC system, like a cabinet cooler, then it is a good idea to clean your cabinet with water and mild detergent.

3. Clean the Inside Area:

Similar to the outside area, the inside area of your HVAC system is equally as important to keep clean. Remember those 9 essential components that make up your HVAC system? It is a good idea to take a closer look at some of these components so your system continues cooling or heating properly. Mainly, you only need to focus your attention on the HVAC’s blower fans, evaporator coils, and control panel. At this point, you can also lubricate any moving parts of the HVAC system, such as fans.

4. Cooling System:

The refrigerant on the HVAC system is its cooling mechanism and it plays a vital role in running your HVAC unit at optimum health. Simply, you want to ensure it is capturing and releasing the proper amount of heat. For this step, it is best to hire a HVAC technician to look at the refrigerant (also known as “charge”) and to check for any leaks.

5. Calibrate:

This one is pretty simple! Test all of your system controls to make sure they are working properly. Ensure your HVAC system turns on and off without any issues, and after that it is best to calibrate all of your thermostats so they are outputting correct temperature readings.

6. Check and Clear Drain Lines:

Last, but certainly not least you should check your condensate drains. A drain’s function is to drain fluids freely, so take a moment to ensure they’re clear of obstruction. It’s not a bad idea to apply an algaecide to prevent unwanted algae growth, too!

Why You Need a Cabinet Cooler

Safe Air Technology Cabinet Cooler
When you need to enclose electrical or other components in a cabinet to protect them from dust and debris, you run the risk of them overheating. When your components overheat, they can lose efficacy, part of their lifetimes, or even fail, costing you money in repair costs, lost revenue, or even emergency evacuations. To solve the problem of overheating electrical components, you need a cabinet cooler, which can alleviate cabinet heat without requiring a full air conditioning solution.

How Cabinet Cooling Fans Work

All cooling fans work on the principle of forced convection, which enhances natural convection – the process of heat transferring from one area to another through air movement – with fans or blowers. As cooler outside air is pushed through the system, the heat generated by the electrical equipment within the cabinet is pushed out through the exhaust vent.
A cabinet fan is an economical answer for any industrial enclosure you may have, as long as the environment is not excessively harsh, like an indoor cabinet without exposure to heavy dust or sprayed liquid. More intense environments or cooling needs may necessitate a closed-loop cooling system, like an air to air heat exchanger or enclosure air conditioner, to properly cool the cabinet.

Is Extra Cooling Required?

Not every cabinet on your property will need additional cooling. Natural convection and heat transfer through the cabinet walls might be enough to maintain the equipment at or below its specified maximum operating temperature.
To figure out if you need a cabinet cooler, you’ll need to calculate the total waste heat the equipment in your cabinet produces while operating, or its heat load. Your equipment’s specifications should list its heat load, so check that.
An example of a calculation is this: say you have a VFD with an operating efficiency of 92% at design load. That means that you’ll lose 8% of the total energy used by the drive as heat, since 100% – 92% = 8%. For, say, a 100 horsepower VFD, that works out to 8 hp of waste heat, or 5,965.6 watts. If your cabinet loses less heat than that via convection and conduction, you’ll need a cabinet cooling fan.

What is “Explosion Proof,” and how do I know if I need it?

Explosion Proof Vertical Wall Mount Package Unit

In your heavy industrial, refinery, or chemical processing plant, you still need a capable HVAC system to keep your workers and machinery cool. However, you can’t use just any HVAC system, since the environment of a plant is more hazardous than the standard house or business Louisiana. You need what’s called “explosion proof” equipment to keep your business and employees safe.

What does “explosion proof” mean?

The term “explosion proof” comes out of the National Electric Code (NEC®), first published in 1897 by the National Fire Protection Association (NFPA). That document defines a number of protection techniques for various hazardous locations, including explosion proof, dust ignition proof, dust tight, purged/pressurized, intrinsically safe, and hermetically sealed.

Each of these techniques contains a number of criteria that must be met by components installed in hazardous locations. The term “explosion proof,” specifically, refers to the unit’s ability to contain any explosion that originates within its housing, and to keep sparks from igniting any vapors, dust, or other particles that are in the air around the unit. It actually doesn’t mean that it can withstand an explosion! It just won’t cause any fires itself.

Do I need an explosion proof HVAC?

Each of the protection techniques laid out by the NEC® is permitted only in specific applications. Explosion proof machinery is approved for use in Class I, Division 1 or 2 locations, so if your plant or building is in a higher class, you might need other equipment. Often, if your building is in a lower class, an explosion proof unit will be acceptable. Products listed for a higher classification often surpass the requirements of lower-classified areas.

If you’re not sure whether you need an explosion proof unit or not for your HVAC needs, the helpful people at Safe Air Technology are happy to answer your HVAC questions! Give us a call any time to describe your needs and we’ll be happy to help. We know what we’re doing and what you will need!
