When NOT to replace the heater

While there are benefits to putting a new central air system in your home, no one wants to do it if it’s not necessary. It can easily cost a few thousand dollars to replace the heaters. Before homeowners think about doing it, they should consider more effective and affordable alternatives.

When necessary, your heater contractor will suggest timely replacements. Otherwise minor problems can easily be solved so that no one has to replace anything in the future.

The air duct system is generally kept sheltered in the attic. Although the material from which the ducts are made is fragile, it does not often leak or leak. However, when this happens, clean air conditioning can leak. At the same time, dirty air from the attic enters the air system. As a result, heating can be inefficient.

Fortunately, a leak in the air duct does not mean that owners should replace the heaters. Technicians can provide repairs to air ducts by sealing leaks.

Air filters should be changed about twice a year. This simple task is something that homeowners can do on their own.

Over-used filters add extra stress to the central air system. This happens because dirty filters restrict airflow, causing the central air system to overwork while collecting accumulation inside.

With enough time and wear, this may require an HVAC technician to replace heater parts due to damage. But it will rarely be necessary to replace it completely.

On the hygienic side

Microbiological growth occurs when the drip pan or evaporator coils collect water. Hygiene becomes a problem as this type of growth enters the air system and the home. Heater maintenance takes care of the problem.

During maintenance, your heater contractor cleans the evaporator coils of any build-up. The condensate lines and drip tray will also be evaluated for any type of microbiological accumulation.

Although your technician may suggest replacing some parts of the heater, the system will continue to operate for service. However, it should be noted that homeowners who avoid maintenance are often scheduled to replace their heater sooner than expected.

Unless the thermostat is in good condition, homeowners will not have access to heating and air conditioning. HVAC technology has vastly improved and there are now smarter, more durable, and more efficient thermostats. In this case, you only need to replace parts of the heater connected to the thermostat, such as the thermostat itself and the wires connecting it to the heater.

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.

How often should I request for HVAC maintenance?

In the electronic, electrical and technological aspects, if an appliance does not receive good care or proper maintenance, its lifetime is drastically reduced. One of these products is air conditioning system, equipment that has very delicate parts that need to be replaced from time to time, as well as periodic cleaning to help prevent possible creation of bacterial and fungal pests inside, with the consequent air pollution in our homes and offices, causing health problems.

The time factor is one of the most important when it comes to maintaining air conditioning. If you only use this appliance in seasons such as summer, you must carry out the following steps before turning it on.

The number of maintenance we must carry out per year depends largely on the use we give the equipment (number of hours per day) and the conditions of the site where it is located. For example, if the air conditioner is exposed to external factors such as dust, car smoke, pollution, or saltpeter, equipment maintenance should be done more frequently.

Taking into account the above, our recommendation is to carry out preventive maintenance in the following periods:

– In homes with moderate use of air conditioning (6 – 8 hours a day) and normal external conditions, it is recommended to perform maintenance every 4 months.

– In homes with intensive use of air conditioning (10-24 hours a day) and normal external conditions, it is recommended to perform maintenance every 3 months.

– In offices, warehouses, restaurants or areas with high traffic and higher thermal load, it is recommended to carry out a monthly or bimonthly maintenance plan. This plan must include predictive maintenance that can detect possible future failures.

– If our air conditioning has a long period of non-use, our recommendation is to carry out prior maintenance before turning it on.

The proper functioning of air conditioning systems not only responds to questions of comfort, health, and well-being of people who work in offices, hotels, restaurants or hospitals, or those who live in air-conditioned buildings. Specialized research units, for example, require exceptionally accurate designs and optimal facilities. There can be no mistake here. The smallest margin could cause local infections, even a pandemic, or dead.

Biosecurity is a matter of life and death. Working in biocontainment tasks does not only concern excellent engineering designs and maintenance services, but it also involves carrying out practices as delicate as preventing the spread of highly infectious agents into the environment, which must remain completely sealed.

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.

Climate-friendly architecture

The term ‘bioclimatic’ refers to bioclimatology or discipline that studies the relationship between climate and living things. In this context, it can be affirmed that bioclimatic architecture refers to the use of environmental conditions for the benefit of the needs of the users of a home.

When designing a building, this type of architecture is based on the climatic conditions of the environment in order to take advantage of the available resources with the least environmental impact and in order to obtain the lowest possible energy consumption for the home.

The traditional thermal draft system with flow and temperature control makes sense in this type of home, but it is difficult to design and limiting when it comes to construction. In contrast, controlled mechanical ventilation can provide the bioclimatic home with optimal conditions for users in terms of renovation and air quality with the aim of achieving high levels of sanitation.

In addition, it can also provide the necessary air conditioning for optimum thermal comfort if the construction has faithfully followed the rest of the previous parameters, in terms of orientation, insulation, etc. The use of these ventilation systems also prevents problems of humidity, mold, and the proliferation of mites and other polluting elements in the interior environment.

In those cases in which the house is located in a place with a hot and dry climate, it may be necessary to use a system to cool the environment. Evaporative cooling systems are ideal for cooling the air in bioclimatic homes since they use water as a refrigerant, and are systems that provide greater energy savings than traditional cooling systems with less environmental impact.

In essence, bioclimatic architecture tries to harmonize construction with the environment by optimizing natural resources in order to cover our comfort needs with minimum energy consumption. Something as simple as making a rational consumption of natural resources and energy, reducing our impact on the environment.

Regarding the soil

The high thermal inertia of the soil produces a climatic effect that can be exploited in this type of architecture since it dampens and retards the temperature variation that occurs between day and night. The semi-burial of buildings or one of their facades can help to take advantage of the heat accumulation capacity of the soil and, in addition, it must be taken into account that a layer of earth can act as additional insulation.

In a house built according to the bioclimatic concept, the capture of energy as a source of air conditioning will be one of the most important elements, although not the only one, due to its direct impact on the energy consumption of the house. In this way, the orientation of the transparent enclosures to the south, allowing solar radiation to penetrate through the glass, heating the elements inside, will allow this energy to be used in the winter months.

As for the suitable materials, we must bear in mind that houses with a high thermal mass behave maintaining a temperature without sudden variations, relatively stable against external conditions. Thus, heavy construction materials such as concrete, natural stone or brick can act as an effective thermal mass. Furthermore, they are appropriate for this type of construction.
