Why does my air conditioner emit a bad odour?

Possible causes of bad odor from Air conditioners:

  • Dirty evaporator coils, clogged condensate drain pans, and stagnant water can cause the smell of dirty socks or stinky feet. Usually, a professional cleaning will do the trick.
  • Air conditioners remove excess moisture from your home in addition to cooling it. When that moisture is unable to drain properly, mold grows easily in areas with remaining moisture. Additionally, dirty filters can give off the scent of mildew. Calling an HVAC technician who is trained in handling mold, mildew, and fungus in these situations is your best bet for getting rid of the smell and improving your home’s air quality

Why is my outdoor unit dripping water?

When using ac on heating it is normal that water condensate comes out of the outdoor unit.

Please visit here for more information

What is the difference between VRF and split AC?

Unlike multi-split or split unit, VRF (Variable Refrigerant Flow) systems are commercial devices that can handle differentiated loads. They continually adjust the flow of the refrigerant to each indoor unit to provide heating or cooling

What is VRF system and how does it work?

VRF systems use heat pumps or heat recovery systems to provide powerful heating and cooling for all indoor and outdoor units. With a VRF system, your building will have multiple indoor units utilized by a single outdoor condensing unit, either with a heat pump or heat recovery system (HR)

Can a VRF system heat and cool at the same time?

VRF heat-recovery systems provide simultaneous cooling and heating as well as heat recovery. This results in transferred energy from cooling zones to heating zones of the building

Why Choose a VRF System ?

DEMAND,  LOW COST & FLEXIBLE With VRF technology, heating and cooling only the spaces that need it is simple. These systems circulate the minimum amount of refrigerant needed for each individual zone to satisfy the building load.

What regular maintenance do the AC system need?

The most important part of an Air Conditioner maintenance aspect is maintaining unrestricted air flow. Dust, dirt, and debris are an HVAC system’s worst enemies. Whether it’s an indoor or outdoor unit, you must keep all filters clean and heat exchangers and coils free of restrictions. We recommend that your heating and cooling system be checked and serviced once every two years; ideally a spring and autumn tune-up. Also, we recommend that you check filters regularly. This alone can eliminate many of the most common problems that need fixing and can significantly reduce the possibility of a serious breakdown.

Solar Panels (PV Panels)

Solar Panels (PV Panels) are an investment that works for you 360 Days for 8 daylight hours depending on the sun exposure. Many people install solar panels because they choose to live a sustainable life by saving nature while reducing electricity bills and creating revenue.

How to decide what you actually need?

When choosing a PV System, durability and reliability are key to making your investment pay you in return. In order to make sure you’re investing in a durable long-lasting product you need to take the following questions and answers into consideration.

Why is the place of manufacture important, when selecting a P.V system?

We care about a greener world and a cleaner environment for a healthier future.

Does the size of a solar panel matter?

A bigger solar panel does not necessarily mean that it generates more energy, the efficiency or the watts per metre squared coupled with the quality is the most important factor to consider.

Product and Performance Warranty? What is the difference?

Most of the solar panel manufacturers offer a 25 years performance guarantee, but it does not mean that they also offer 25 years of product guarantee.

 

The manufacturer carries a product guarantee to get support on repairs parts and most importantly, a Reliable After Sales Service. BT Commercial offers a backup of 25 years and a performance warranty with highly qualified after-sales service at any time needed.

What should I consider for maintenance?

Solar panels need maintenance as well. When you think about the fact that you will own an asset for electricity production that you rely on it for the next twenty years, taking care of it should actually be one of your top priorities.

The first thing to do is to combine your solar panels with a monitoring system. Without data, it is much more difficult to know if your system is working properly. The monitoring application will help to identify issues and address them where needed.

It is of great importance that the system is maintained regularly, thus by cleaning the panels and observing shadowing caused by leaves, bird droppings, or any other deposits and scheduling maintenance to check structure, Inverter output, and connections visible module connections and cable. Choosing a long-term reputable company that offers you complete after-sales services in case you need, them is most important.

When choosing a photovoltaic system, should I pay attention to the hail resistance class?

We are aware that the climate is changing resulting in abnormal weather conditions which can cause medium to high-level storms to develop into hailstorms causing damage to agricultural crops, buildings, and vehicles every year.

Most photovoltaic modules are certified according to the IEC 61215 standard. This standard requires a hail test with 25 mm hailstones which Certify the durability of the modules.

How can I control electrical consumption at my home to get better result?

You may need to change your electrical water heaters to other sources to reduce your electrical consumption in order to reach your goal to reduce your electricity bills. BT Commercial offers alternative solutions for efficient water heating and can give you a comprehensive solution to reach your goal of reducing your electricity bills for a long time.

How can I generate income on my PV System?

PV Systems come with a varying number of panels resulting in the power output of the system. Output depends on the efficiency of the panels.  However, your roof space and Orientation can affect the amount of electricity you can produce. BT Commercial specializes in customer requirements and gives the best solution for each individual customer, the company can offer customized solutions depending on the budget and roof space available. So, if you have a lot of roof space you could be generating electricity to sell, creating a new source of income.

How can I cope with shady areas?

The amount of shade your roof gets will also affect how you install your PV system. We can offer solutions for Optimization in shady conditions by inverters that can be installed on partially shady roofs. These types of inverters are combined with power optimizers that are installed with each panel to increase energy output from PV systems by constantly tracking the maximum power point (MPPT) of each individual module

What is composed of a P.V system?

A PV system is made up of 3 main parts: the panels, the Mounting Structure (Supporting-Stand), and the Inverter. The Panels come in mainly 2 types, monocrystalline or polycrystalline. Because of lower silicon purity, polycrystalline solar panels are not quite as efficient as monocrystalline. Obviously, there is a price difference, the higher the efficiency the more expensive the panel.

Is the design related to the mounting structure important?

The Mounting Structure is required to mount the panels at the best angle so that solar efficiency is assured. The structure is also important as it needs to withstand the aggressive Maltese winds and salty weather /rainfall.  Moreover, since the panels are a long-term investment, the structure should be robust and strong enough to withstand corrosion. Our mounting structure is made out of 5mm thick anodized aluminum, that is Euro-coded and certified for the Maltese Climate.

What is the inverter? How it optimizes the Performance for shaded panels?

The panels produce Direct Current (D/C) power and the inverter then converts this D/C power into Alternate Current (A/C) power at a voltage that is equal to the local grid. An Inverter with Optimizers is specifically built to compensate for panels in the shade. This gives your PV system an edge over other inverters at producing electricity when part of the system is in the shade.

Electricity produced from the panels is fed into the inverter. A cable extends from the inverter into the government mains box. This allows you to use the electricity that you produce and also feed the grid with any extra electricity that you produce. This electricity is then used by the neighboring homes which will pay for electricity and Arms pays you for producing it.
