Tips for choosing the best industrial HVAC service for your company

HVAC systems -that is, cooling or heating a space- account for almost half the energy expenditure of an average home. Therefore, creating an adequate maintenance program for the air conditioning units that your clients have installed at home is vital. And of course, using the right software can make these maintenance visits more streamlined and efficient.

Over time, the filters in air conditioners get dirty, and their cooling system loses power. The maintenance program ensures regular check-ups, and with it, not only great energy savings and more efficient work, but also healthier living conditions for all family members.

Doing research to find the best industrial HVAC service will make the difference between getting a professionally installed solid air system or just being ripped off. Fortunately, there are still organizations that are concerned with providing a quality service and in a very professional way, so in this article we will take care of showing you practical advice to choose the best industrial HVAC service for your company, with which it can be guaranteed efficient operation of your air conditioner for years to come:

1. First, be wary of an HVAC contractor offering you a quote or an estimate over the phone, as there are a number of factors that need to be properly inspected on site: What is your pipeline like? Is there an adequate number of records per department? What type of insulation do you have? What kind of windows does it have? The ability to answer these questions will determine how qualified a technician will be in performing the job.

2. Verify that the contractor replaces the old air conditioner with the same type of unit as before. Keep in mind that properly trained personnel will recommend various options to update the installation and increase its efficiency.

3. Ensure the contractor is well versed in cutting-edge technologies, including the most up-to-date HVAC industry service and that goes hand in hand with automation of building air conditioning systems.

4. The Industrial HVAC Systems Technician must possess a license certifying his experience in handling gas lines, as well as electrical and plumbing applications.

5. Demand a written offer or quote. Any reputable HVAC contractor will give you a written offer to adhere to, which should include a list of everything that will be done, as well as its cost.

6. Read Google reviews online and avoid Yelp, as it filters reviews, while Google does not.

7. Avoid going with the lowest HVAC industrial service bidder this can cost you more in the long run. The main reason is that air conditioning is a machine with moving parts that will (hopefully) run for 10 to 15 years, and if not installed correctly it will do one of two things: it will either not keep the building properly cooled or warm and otherwise it will fail completely.

A clean and air conditioning system checked from time to time is the best guarantee of correct operation, a clean environment and, of course, the ideal temperature for each season. Remember, who installs your HVAC unit is more important than the type of unit you buy. A good HVAC contractor can make anything work efficiently.

Why Aerothermal is the next step in renewable energy

The term aerothermal is undoubtedly fashionable in the world of air conditioning. If you have recently changed your heating or air conditioning system, you will surely have heard about it. If you are looking for a home, you have probably been informed. Even if you stay fully aware of this world, you may have heard about this technology at some point.

Air conditioning with aerothermal energy is a system that uses the energy of ambient air to produce cold through thermodynamics. In this case, the apparatus that will convert aerothermal air conditioning is a reversible heat pump.

The aerothermal heat pump is the most efficient system to reduce the temperature of any space since the heat pump always delivers more energy than it consumes. In other words, aerothermal stands out for its high performance.

For every 1 kWh consumed by an aerothermal heat pump, you get 4 kWh of heat energy. These data make aerothermal heat pumps tremendously efficient and environmentally friendly since the use of energy is excellent.

Another advantage of air conditioning with aerothermal energy is that the heat pump captures energy from a renewable source that is ambient air, converts it into usable energy and reduces dependence on other more polluting sources.

Depending on how the heat transfer is performed, different systems generate air conditioning with aerothermal energy:

Air-to-air aerothermal

In this type of system, the heat is transferred to the outside and the equipment transfers fresh air directly to the room.

Depending on the type of installation, it can be a split or multi-split unit consisting of an outdoor unit (the condenser) and one or several indoor split units (the evaporator).

Air duct air conditioning systems also use air duct air conditioning installations whose distribution is done by expelling air by cooling through a system of grilles strategically placed on a suspended ceiling.

Air-water aerothermal

With air-water aerothermal heat exchange takes place in a circuit of water that cools and that water cools the ambient air. This exchange can be done through two systems: refreshing soil or fan coils.

In a cooling floor system, the machine passes cold water through the floor. It is valid for areas with low humidity and those that are not very hot.

The fan coil unit receives cold water from the outdoor unit. A fan drives the air and makes it pass through the tubes through which the cold water passes, causing the temperature change here. After passing through the filter, the refrigerated air comes out, air conditioning the environment.

As in almost all cases, the convenience or not of this type of equipment depends on your needs and those of your installation. There is no definitive solution in terms of air conditioning. In general, it is a good alternative in most cases and certainly an option to have when choosing a type of solution.

A guide to best practices regarding air filtration and ventilation in the current crisis

The current health crisis underscores the responsibilities of HVACR engineers, along with service and maintenance personnel, building owners and operators, to carefully assess building ventilation systems and conditions. Adequate ventilation, with a greater degree of fresh air supply, use of the correct types of air particulate filters, and careful maintenance can be important factors in the containment of the COVID-19 outbreak.

Breathing, as well as coughing and sneezing, releases tiny infectious droplets into the air that can contaminate the surrounding surfaces and, of course, the surrounding air. These droplets, called aerosols, can be of various sizes, from 1 to more than 10 µm (micron or micrometer, 1 micron equals 0.001 mm). Experts assume that viruses do not occasionally fly in the air, but are always trapped in droplets or attached to other particles.

This raises the question of how ventilation and air conditioning systems play a role in the transmission or containment of epidemic diseases such as COVID-19. Here are some basic recommendations that directly or indirectly influence the spread of viruses and the well-being of people in occupied spaces.

Indoor air quality has become a popular topic in recent years as more and more countries shift their focus to the health and well-being of building occupants in their everyday lives. Most people in the industrialized world spend up to 90% of their time indoors. Exposure to air pollutants, from dust to spores, bacteria, viruses, and chemicals, has a direct influence on people’s immune systems and can cause a variety of conditions, from allergies to cancer or – an epidemic disease like COVID-19.

Maintaining a healthy indoor air quality thus becomes a general and basic but extremely important necessity. While this is true at all times, it is imperative in times of a broader health crisis to prevent not only the direct spread of a virus but also to support people’s immune systems so that they can withstand more serious impacts of aggressive disease and thus reducing pressure on a health system that fights against overload.

While normal air filters are not designed to prevent the spread of viruses, they are essential to minimize the risk, as viruses tend to adhere to airborne particles and aerosols. Therefore, regular filters with high filtration efficiency (ePM1 filters) are crucial to reducing the risk of airborne diseases.

Order an inspection of the air filtration system in place and make sure that an ePM1 filter is installed. Call an expert to evaluate the filtration systems if you are not sure. Any air filter that removes particulates from the air has the potential to reduce exposure to Covid-19. As companies increase air rotation at their facilities, they must also filter air flows more aggressively.

The first step is to increase the filtration rate. The current industry standard for commercial HVAC (heating, ventilation, and air conditioning) systems in stores and restaurants is to use filters with a MERV 8 rating. It is recommended to replace them with filters with a MERV 13 rating, which are designed to filter out viruses and bacteria in the air.

In addition to updating filters, companies should also increase the frequency with which they replace filters, and if they generally change filters on a quarterly basis, doing so every 30 days, for example.

7 tips to save energy

The good weather arrives and the heating gives way to the air conditioning. It seems that with the good weather and the rising hours of sunshine, you will less turn on the light and save on the bill. A false belief that can be counterproductive if efficient and responsible use of air conditioning is not made in summer

To establish average consumption and be aware of the expense involved, you must know how much the device actually consumes. For example, if your air conditioner has an electrical power of 2000W every hour (2 kW per hour), it means that every hour that the appliance is cooling at full power, it will consume 2000 W.

The air conditioning is a perfect tool to be comfortable at home, not suffer from heatstroke and benefit from today’s technology. However, not making efficient and responsible use of it, can have a negative impact on our health, because the worst colds are caught by excess air conditioning and in our pocket.

Below, we have prepared a list for which you take note of how to save and make efficient use of the air conditioner:

  1. First, choose an efficient device. All appliances have an identification label indicating the degree of efficiency it has. The letter A, accompanied by “+” and the color green, is indicative of an energy-efficient device. Acquiring an efficient appliance saves 40% on energy consumption.
  2. Install the devices as far away from direct sunlight as possible. If the sun constantly gives you it can not only damage the system, but it will cost you more to function and therefore consume more.
  3. Set the device at a medium temperature. The thermostat should be set at 24 degrees, however, the body must adapt to the Summer temperature, and you should go with lighter clothes and set the thermostat at 26 degrees. You should know that the maximum difference between the temperature outside and inside must be 12 degrees. Every degree of difference you put, you will consume 8% more energy.
  4. If you have it, install the Eco mode, as it allows you to reduce consumption by 30%.
  5. Avoid putting it at night. Also if you have a special mode of lower consumption, it is better to lie down when it is fresh and turn it off. Open the windows to make current and reduce many hours of consumption.
  6. Insulate your home. Good insulation maintains the indoor temperature. At night, open windows and shutters, letting the air in, and in the morning, when the sun goes down, lower the blinds to keep the indoor temperature and prevent it from heating.
  7. Clean the device regularly. The air filters, when they are dirty, force the unit to consume more energy than usual to be able to cool.
