How is Air Filtered in Commercial HVAC Systems?

There are a few different ways that air is filtered in commercial HVAC systems. The most common method is through the use of an air filter. Air filters are designed to remove airborne contaminants from the air that passes through them. They are typically made of paper or cloth and can be replaced when they become clogged with dirt and debris. There are also electronic air filters that use negative ions to trap dust and other particles, but these can be more expensive than traditional filtration systems.

UV Systems

Another common method of commercial HVAC system air filtration is through the use of UV lights. These are installed directly above cooling coils or heat exchangers, where mold and bacteria can grow. The UV light kills these contaminants, preventing them from being circulated back into the air.

HEPA Filters

HEPA filters are also sometimes used in commercial HVAC systems. HEPA stands for high efficiency particulate air and these filters are designed to remove 99.97% of all particles that are 0.3 microns or larger. These filters are used in applications where there is a high amount of dust or other pollutants in the air.

Custom Settings

In addition to these filtration methods, commercial HVAC systems can also be designed to improve ventilation and circulation within a building. This helps remove airborne contaminants from occupied spaces, particularly when large amounts of people gather in enclosed spaces. Proper ventilation and filtration can help ensure that air quality remains high in even the most common areas of commercial buildings.

As you can see, there are a variety of ways that air is filtered in commercial HVAC systems. Whether you are considering installing an HVAC system or have one already, it is important to understand how the air is being filtered so that you can get the most out of your system.

The Most Common Summer HVAC Problems

As summer dwells up on us, it is time to get the air conditioning (A/C) units running. For many buildings, the A/C unit has sat idly by since last Fall. Before you begin to turn on your A/C, it might be wise to get an inspection done to prevent it from breaking down on a sweltering day. Here are some of the most common problems a commercial HVAC unit faces during Minnesota’s hot summer weather.

Improper Air Flow

If you sense that your system’s air flow is weak, the first place that may be the problem is the filter. Dirt and debris accumulate over time, and if the filter has not been changed, the blower goes into overtime to ensure air is moving efficiently. Clogged filters not only decrease airflow, but the blower motor consumes more electricity. This results in higher bills and uncomfortable settings. The filter should be replaced regularly throughout the year. Make sure to schedule an appointment with a trusted HVAC company for a thorough inspection.

Clogged A/C Condensate Drain

A clogged drain line is another common problem seen in A/C units in the summertime. Condensate is a byproduct that occurs normally in the air conditioning process. But sometimes, it can be backed up with debris, dirt, or dead bugs. Clogged drains can lead to water leakage from the A/C into your building. A clogged drain is usually a simple fix, but sometimes the HVAC unit will require a more thorough cleaning.

Refrigerant Levels are Low

Your air conditioning unit requires a certain level of refrigerant to keep the building cool and operate properly. However, over time small leaks in the system can cause the refrigerant to escape. This could result in an undercharged A/C unit.

Undercharged air conditioning units will have a difficult time maintaining the desired temperature. The refrigerant used in HVAC systems is regulated by the EPA, so it is essential you have an experienced HVAC technician such as Altemp Mechanical repair any leaks.

How Optimizing your HVAC Can Ease Allergy and Asthma Symptoms

Springtime can be one of the worst seasons for allergy and asthma sufferers. HVAC systems can have a direct role in alleviating some of these symptoms, as a highly optimized system can reduce pollutants and improve air quality. There are many straightforward options for optimizing your HVAC to reduce its spread of pollen and other pollutants. Managing your HVAC settings in a commercial HVAC system is just as important as it is in a residential area.

Invest In a Quality Filter

The air filter is crucial in reducing indoor allergens. High-quality filters can trap the smallest particles. Its effectiveness is used on the MERV rating, which stands for minimum efficiency recording value. This rating system scales from one to twenty, where the higher numbers offer the highest filtration.

Air Purifiers Can Be a Tremendous Help

Centralized HVAC systems work well with high-efficiency air filters. Adding an air purifier can also be a smart investment for trapping the allergens that your HVAC cant catch alone. Air purifiers will help with indoor air quality, making the air much easier to breathe. This is especially important for the warmer months.

Humidity Control

While air purification control is highly advantageous, controlling humidity levels will help alleviate allergy symptoms. Humidity control is also important for creating a comfortable environment/ Dehumidifiers can be installed to make sure that the humidity levels are well-balanced. This will create a safe environment that is both comfortable and healthy for everyone.

Ongoing HVAC Maintenance is Key

The most cost-effective way to reduce allergy and asthma symptoms in a commercial setting is to schedule regular maintenance services. A professional commercial HVAC company can identify any existing problems and give guidance on how to best optimize your system given your setting.

What Causes Frozen Heat Pump Coils?

Many people may have a hard time believing that their heater can in fact freeze. Heaters produce heat, so shouldn’t that prevent freezing? Unfortunately, despite its nature, a heater can freeze and it can lead to a disastrous problem.

Heaters typically freeze due to poor airflow over the heat pump coils. When the temperature plummets, the pump coils will end up freezing. Functioning heat pump coils can withstand even the most drastic temperature drops, but some things can lead to freezing coils. Here are the most common causes.

Air Filter Needs To Be Cleaned or Replaced

Changing your air filter regularly is crucial for the performance of your heater and air conditioner. Over time, air filters will clog up with dust and dirt. This will block air from going through and passing on to the coils. When this airflow is interrupted, condensation will build up around the coils, which will eventually cause the system to freeze.

Outdoor Unit May Need Some Maintenance

Your outdoor HVAC needs to be regularly maintained and free of debris, such as plants, dirt, dust, and so much more. If the unit has settled in, it could lead to its foundation sinking. This will also reduce your airflow. Make sure to sweep through the area, and in the winter, try to scrape off excess snow as well. This way you can ensure it is operating to its fullest capacity.

The Coils Are Dirty

While there could be many factors that cause a system-wide freeze, the coils themselves may be the culprits behind the problem. Dirty coils transfer heat poorly, and even the thinnest layer of dust can prevent the heat from transferring properly. That’s because dust can act as an insulator. This results in a lack of heat transfer, and the coils’ temperatures will be behind to drop.

Many factors can cause an HVAC system to fail. Make sure to have yours regularly inspected by a trusted HVAC professional such as Altemp Mechanical. To learn more or to schedule a service call, feel free to contact our company online or by phone!

Spring Checklist For HVAC Maintenance

It’s that time of year where winter is ending and spring is starting. Although it might not feel like it yet, summer will be just around the corner. And we all know one thing about Minnesota summers: they can be hot and humid. That’s why your AC must be in working condition.

The best time of year to have HVAC maintenance is mid-season. As your furnace is shut off and prepared for the air conditioner in the summer, a little bit of upkeep will be incredibly beneficial. Taking preventative measures will help ensure your system is running perfectly come summertime. Here are some tips for any property owner wanting to keep their HVAC system in perfect condition.

Clear Out Debris From Your Outdoor Unit

Fall and winter bring debris buildup to practically every building and HVAC unit. If you are a busy landscaper or gardener, you are likely used to clearing out debris for your yard. So you should take the extra minutes to clear up any dead foliage and junk that has accumulated by your outdoor unit. This can help cut down on any stress your unit will have during the warm months.

Look For Any Damages

You never know what kind of damage the snow and wind can bring over the winter. Make sure your HVAC unit has a stable surface and look out for any serious damages. A damaged condenser could become a big problem when you need to crank up the A/C in June.

Clean Your Ducts

To enhance your indoor air quality, it might be a wise idea to schedule a duct cleaning. Before your AC is turned on, you should have all the dust, allergens, and mold removed. Since it can be sweltering in the summer, the last thing you want is to develop health complications from poorly maintained HVAC units.

Look For Leaks

Even if you properly maintain your HVAC system, it won’t do much if your building isn’t properly sealed. Look for areas where you feel a draft. These could be doors, windows, and door jambs. If there are any cracks or signs of cracking, it might be time to reseal or replace them. A properly sealed building will help with filtering your air, as well as keeping your building cool.

Every building needs a functioning HVAC system. Regular maintenance is kept in keeping your unit working properly for as long as possible.
