How To Maintain Your HVAC System
You may think that your heating, ventilating, and air conditioning (HVAC) system does not need regular maintenance, but you would be wrong, even if it is a brand new system. The fact is, not only can your system fail if it is not properly maintained, but the health of the occupants of the building can suffer as well. Besides, HVAC systems are an expensive investment, and there is no reason why you should not protect that investment with regular maintenance. Here are some steps to take when maintaining your system.
Filters
Changing the filters regularly may be the single best way to prevent illness and poor air quality. It helps prevent water from pooling and collecting mold and bacteria. Filters are rated using a system called MERV. The higher the rating, the more effective the filter. A clear filter allows the system to more easily cycle air through. If it is clogged, then it will spend more energy pushing air through the system, plus that air will be contaminated by the nasties stuck in the filter.
Do Not Allow Pooling Water
The air conditioner intake is a prime spot for water to collect, creating a breeding ground for bacteria. Cleaning back the tree line and keeping the roof clear will help keep debris and dirt from getting into the unit. The drain lines that carry condensation away from the unit should also be kept clear and free flowing.
Evaporator and Condenser Coil Cleaning
Evaporator coils collect moisture, which promotes the growth of mold. Air coming into the building passes over those coils as well, meaning contaminated air gets spread throughout the building. Coils should be cleaned using and antimicrobial cleaner. Ultraviolet lights may also be effective in preventing mold. However, most HVAC systems do not come with ultraviolet lights, so they would have to be installed afterwards, potentially using a separate power source.
The best thing for your HVAC system is to keep it running at its best at all times. That means even if it is a brand new system, maintaining it regularly and keeping it clean. This will make sure that the air in the building is not causing illness, and also ensure that the system is running as efficiently as possible.

Researchers Look to UVGI To Improve HVAC Performance
HVAC Innovation
Researchers are looking into a new way to improve the air quality and energy efficiency of heating, ventilation, and air conditioning (HVAC) systems. A team from Penn State University have been testing whether ultraviolet germicidal irradiation (UVGI) would work to help maintain cooling coils and keep them clean.
The team went about testing the air flow, humidity, and pressure drop before and after cleaning the cooling coils with UVGI. They will then use that data to measure what the benefits would be of using it.
HVAC Operations
When an HVAC system is running, microorganisms collect on the coils that transfer heat throughout the system. These fungi and bacteria, along with other materials, can build up to a point that affect the performance of the system as a whole. More energy is used to make up for the gap in performance. Not only that, but the microorganisms are also spread into the building. The condensation that forms on heat transfer coils are what make them particularly susceptible to contamination.
What to Do
There are a few current options for cleaning the coils. They include mechanical and chemical methods. UVGI is also currently used, but because there is very little research about its effectiveness, it is not common. UVGI is a common disinfectant for other applications, but there are concerns not just about the effectiveness for HVAC systems, but also whether it negatively affects air quality. This new research is meant to make determinations on these questions.
The project is currently operating at two test sites. Not only will they be collecting immediate data, but they will also collect data over time to see if the results hold up in the long term. That way, they can see if UVGI continues to be safe and effective after several uses.
The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) have been working to “maximize the actual operational energy performance of buildings and facilities,” and this research coincides with that effort. The hope is that UVGI will prove to be a safe and effective cleaner for HVAC systems, and can be used more widely.
There is a movement across all industries and sectors to be more energy efficient and safer in all things. HVAC systems will continue to improve in both factors through research like this.

How To Protect Your HVAC System During a Hurricane
From the recent hurricane activity over the summer, it should be obvious to anyone that hurricanes can cause a massive amount of damage. When it comes to protecting your home, it’s always best to be prepared well before a hurricane strike is imminent. This includes protecting your HVAC system from the elements. Your system can sustain massive damage in several ways from a hurricane. Here’s how to protect it.
Disconnect The Power
If you air condition your home through window units, then make sure to disconnect the power. Also, you should remove them completely from the window. The high winds could end up blowing the units into your home and causing damage and injury.
Put a Cover On Your HVAC Unit
If you don’t use window units, then you’ll need to protect your outdoor unit as well. It can’t be moved indoors, so a simple tarp that covers the entire unit should work just fine. You will need to strap it down securely, however, so it doesn’t blow away. The tarp will help protect it from the elements, as well as from any flying debris. While you won’t be moving it, you should also try to anchor the unit in place. It may be too heavy for you, but it might not be too heavy for the hurricane. You can purchase straps that have been specifically designed to anchor your HVAC unit in place.
Get Surge Protection
A big part of hurricanes is the amount of lightning that comes with them. If your home gets hit and has a power surge, your HVAC system could be destroyed, along with any number of other appliances. You can purchase a surge protector that will ensure that everything in your home is protected. It’s also wise to switch off breakers to the thermostat and the HVAC unit until the storm passes.
Inspect Your Yard
While a tarp will provide some protection, it won’t defend well against certain things. Inspect your yard for lawn equipment, toys, large branches, and other objects that can be swept up in the wind.
Do not be caught flat-footed when a hurricane strikes. Make sure to take every precaution to protect your HVAC system.

What New Technology is Changing the HVAC Industry?
We live in a world where we are becoming more connected all the time. We can contact whoever we want from a device we keep in our pocket, and access any information we need using that same device. Our homes are no different. More and more products are coming to the marketplace to help us be connected to, and automate, our home lives like never before. Should HVAC contractors be selling these products along with traditional ones, or leave that to the larger companies and big box stores?
Fringe Items
“Fringe items” is the new buzz term for items that will help connect several aspects of your home. They include locks, sprinkler systems, and lighting systems, for example. For heating and cooling, there are many new options on the scene that contractors can potentially offer to their clients. However, the HVAC industry as a whole has not embraced this new technology in the same way that other industries have. It may be time for contractors to start training both themselves and their staff on new technologies, so they can start seeing the benefits. Once they see the benefits, they will be able to more effectively sell those products and services to their customers and improve their lives.
How it Could Be Successful
It seems that for many contractors, it is all or nothing. They have either embraced home automation, or ignored it completely. The latter group may end up being squeezed out. Selling fringe items means getting to know your clients, and finding out what their needs are. The best thing about new options and technologies is that there is more of an ability to customize, so there’s no reason a client canot get what they want. HVAC contractors are in a unique position when compared to contractors from other industries who are in the home automation game. They often already have paid memberships, and they visit clients’ homes several times a year in some cases. With that relationship comes trust.
Since the world is getting more connected, there’s no reason that the HVAC industry should not embrace the changes. Making clients’ lives easier and providing them with the service should be the primary goal.
Tips to Save Air Conditioning Energy This Summer
There may be nothing better on a summer’s day than to come in from the hot weather, thirsty and sweaty, to a nice cool building. Air conditioning has become a lifeline for so many in the summer who cannot stand the heat. Unfortunately, your air conditioner uses a lot of energy, and can be quite costly. Here are some tips to keep your energy consumption low this summer.
Seal and Insulate
Make sure your building is well insulated, and seal any spots where air from the outside can get in. If hot air is coming in, then your HVAC system will have to work harder to cool down the building, which will cost you money. Your entire building should be well insulated as well, to keep the heat out and the cool in.
Use a Fan and Shades
Yes, a traditional fan can save energy. A standing fan or a ceiling fan can help circulate the cool air to better cover every spot in the building. On days that are not too hot, you can turn off your AC and use fans to be cooled by their breeze. Shading your windows will also help prevent your building from getting heated up by sunlight like your car does on a hot day.
Use a Programmable Thermostat
A programmable thermostat can be set to only run the air conditioning at certain times of day when it is most needed, or to maintain a certain temperature. You can set it to a slightly higher temperature than what you originally want, as well. Instead of setting it low to get an immediate blast of cold air, set it a bit higher. You’ll cool more slowly, but you will not work your AC system as hard.
Use A Swamp Cooler
A swamp cooler evaporates water in the air, so that the area cools. It uses much less energy than a compressed air AC system. The windows should be left open for this method.
Maintain Your Filters
Your filters can get clogged with all sorts of debris, so make sure you change them regularly, especially if you have pets. The less airflow there is because of a clogged filter, the harder your AC unit will work.
Do not let your energy costs get out of control this summer. Save energy with these helpful tips.
Tips for Office and Warehouse Air Conditioning
We all know it is tough in the summer to live in a home with no air conditioning. Sleeping can be difficult and uncomfortable, cooking makes it even hotter, and you probably do not want to snuggle with your kids or a significant other. What about work, though? It is important for workplaces to be kept comfortable as well, so keep staff and customers happy. Here is some advice regarding air conditioning in commercial settings.
Capacity
With larger spaces holding more people, the unit at your office or warehouse should have more capacity than a residential unit. People, plus machinery, combine to heat up the property, so you need to have the power to cool everything down.
Evaporative System
In a factory or any large commercial space, there are extra challenges when it comes to cooling them down. An evaporative air conditioner might be a good option. They use less energy than traditional air conditioners, which means they’re cheaper to run. They are very good at cooling large factory settings with lots of hot machinery, as well.
Machinery
Speaking of machinery, you would be surprised at how much they can add heat to a building. And it is not just large factory machines, either. Computers, printers, and photocopiers will also give off heat and make any office hotter. When you’re getting a quote for air conditioning, make sure to notify the contractor how much machinery you have, so they can get a good gauge on how much capacity you’ll need.
Keep Everyone Happy
There is no doubt that productivity can suffer if a workplace is not property air conditioned. Instead of working, staff will be fanning themselves, talking to each other about the heat, and generally being distracted by their discomfort. Also, if you have an office or a shop where clients come in to see you, then they may not come back if they were not comfortable. The important thing is setting your thermostat so there is a good balance between too cold and still hot. You’ll have staff and clients that have different comfort levels, so it is important to try to please everyone as best you can.
It is important for any workplace to provide a comfortable space for both workers and clients. Use these tips to keep productivity and comfort at high levels.
