Fan Systems/Bathroom Exhaust Fans – What to Look For!

Bathroom exhaust fansWhether your bathroom provides a luxurious shower similar to a spa retreat, the humidity and steam coming along with the shower water might be causing destruction on the quality of air. That is why it is advisable to include the bathroom fan to enhance the quality of air. Bathroom exhaust fans are installed either into the ceiling or wall and designed to improve airflow, add ventilation, and decrease excessive humidity level.

Literally, they get rid of warm moisture from the bathroom and drain it to the outside through the house’ ducts. The bathroom fans help prevent problems brought about by mildew and mold, and therefore maintain a healthy indoor air quality as well as keeping your family safe and comfortable. Therefore, below are the 5 main things to consider when buying a bathroom exhaust fan.

The right size

If you select the right size of bathroom fan based on the bathroom’s size, you will ensure that sufficient ventilation is achieved. The exhaust fans are rated and sized by their capability to drive air in cubic feet per minute (CFM). A small and less powerful fan will move less air and therefore suitable for small bathrooms. Those units that can generate higher CFMs are perfect for larger rooms.

Exhaust fan installation

Bathroom exhaust fans installationBathroom exhaust fans can either be installed into the ceiling or wall. Most of the units have integrated duct adapters which connect to a home’s ductwork. The fan should be installed in such a way that it moves air outside of the house through the ductwork. Remember, the air should not be vent into an attic because it transfers moist warm air to another room area within the home, leading to moisture problems. So, consider the place to install the unit, choose a model with the right duct adapter size for your home.


Most of the modern bathroom ventilation fans have various features, which can enhance their operational convenient and effective. Some models have integrated lights, which can reinstate the existing fixtures or include additional lighting. You can find some of the fans with night lights to provide smooth illumination during night time. For those living in colder areas, fans with built-in heaters can be ideal for adding warmth in your house.

You can enhance energy conservation in the house by choosing fans with motion and humidity sensors. Motion sensors detect when a person enters the bathroom and turns the light or fan on. Humidity sensors monitor the bathroom and also stimulate the fan to turn on whenever the level of humidity rises above a certain point or turns off when the humidity drops. The fans with several functions have separate controls for every function or have the option of using all the functions together.

Bathroom exhaust fans types

Noise level

There are some bathroom fans that produce a loud noise, which can interfere with the peaceful retreat that you deserve. While shopping for a fan, you will come across different models that produce different levels of noise – so, choose a quieter fan. Bathroom fan sound is measured in sones based on how it is sensed by a normal listener. If you are looking for a quiet fan, it is advisable to choose a model with a sone rating of 2 or below.


When shopping for a home appliance or system, efficiency should be at the top of your mind. Interestingly, most of the today’s bathroom exhaust fans are more efficient than the traditional ones. For instance, Energy Star fans use 70% less power compared to other conventional and non-Energy Star fans. This means you rest assured of saving on energy. Apart from the general efficiency in energy consumption, reliable fans must meet the low sound emission qualifications, low wattage rating, powerful, and efficient performance.

Before buying a new bathroom exhaust fan, check if it is an Energy Star model so that you can get the benefits of energy saving. It is also recommended to buy a fan with motion and humidity sensor so that it can operate when required. Finding a bathroom exhaust fan is not an easy task given the many things that need to be considered. However, you can seek assistance from a professional bathroom fan installer to give suggestions on the best choices based on your needs.

Tech Changes in 2017/Quiet Air Conditioner Innovations

The issue of renewable energy reliance has been proposed by many state governments across the globe. Relying on renewable energy sources has various benefits including promotion of low carbon production development, as well as addressing energy security issues while steering up economic growth. This trend has also been integrated into HVAC technologies. Many companies all over the world are involved in research projects that are geared towards creating a more energy-efficient traditional system, and also a new type of system that runs off alternative energies such as solar and geothermal.renewable-energy

There are green technologies that are bringing changes to the HVAC systems. Also, more improved technologies are expected in the near future as tech companies continue working towards changing reliance on fossil fuels. Consequently, many experts are always looking for ways to improve air conditioners. Every year, various air conditioning technologies are being introduced in order to make the ACs perform more effectively. The modern ACs are more efficient than the traditional models. Additionally, they have become a bit affordable and that is why they are a norm nowadays. As a result, many people are using air conditioners to have a better home climate.

The following are some of the new innovations and technologies in 2017.

Thermally-Driven Air Conditioning

green technologyA thermally driven chiller that is created by an Australian company, Chromasun, offers a low-cost option to the traditional air conditioning units that are electrically powered. These chillers utilize solar energy, but they can also be supplemented by natural gas when the solar power is running short. The solar panels, which are made by the same company, generate high temperature for driving the double-chiller system effectively. The system is said to offer a more improved cooling compared to a photovoltaic system, hence eliminating costs of electricity.

Ice-Powered Air Conditioner

The Ice Energy uses an ice-powered unit known as the Ice Bear to provide cooling in buildings as well as reducing building’s total energy consumption. The Ice Bear functions through chilling 450 gallons of water in a tank and then make the frozen water available for cooling the following day. The Ice Bear is turned from its Ice Charging into Ice Cooling mode so that it can provide cooling for more than 5 hours. Once the ice melts completely, the cooling reverts back to the conventional commercial building AC unit. This is why the Ice Bear works together with a conventional unit.

Quiet-Duct Wrap

Unlike many of the latest technologies, duct wrap has been around for quite some time.  The Quiet-Duct Wrap is considered a green technology and the distribution is available in a few countries including the US. It is made of recycled denim fabric, which has been sidetracked from the landfill. While it has low VOCs and no irritants, it also reduces heat loss and gain, which happens via the air ducts. With the absence of fiberglass, it eliminates the possibilities of skin irritation and itching, as well as carrying a Class-A Fire Rating. It has an aluminum barrier that offers protection from moisture, air currents, vapors, as well as reflecting unnecessary radiant heat.

Energy Analysis Software

According to Trane, a world’s provider of heating and air conditioning systems, the energy analysis software can be used to project an energy efficient and cost-saving HVAC system for a particular space before installing and using the system. It can also be used by architects and engineers as an appropriate tool for designing purposes. The equipment can be used to project the energy usage of a building as well as taking into consideration the outcome of non-HVAC methods such as applications of reflective roofing.


Some of the air conditioning technologies have not been approved fully, and therefore they are still concepts. However, once they turn to be a reality, there will be many changes as far as air conditioners functionalities are concerned. Sound-wave cooling and smart-metals are also other technologies in the AC industry. The sound-wave cooling utilizes the helium gas rather than the refrigerant. On the other hand, the smart-metal is still a concept and uses shape memory alloys capable of transforming in response to applied stress, and thus capable of removing heat from a room during the transformation process.

A Complete Tech Guide to Wine Refrigerators

wine collectorIf you are a serious wine collector, those traditional wine racks are no longer a suitable choice to store your treasured investment. A true wine fanatic, of course, will buy some expensive and sensitive wine bottles that require right storage conditions in order to maintain the quality. The best way to store your wines is by use of wine refrigerators as they ensure the bottles are carefully kept at a controlled temperature.

In this guide, we shall briefly look at the key reason to buy a built-in wine cooler or a built-in wine refrigerator, types of built-in wine refrigerators, and things to consider when buying a new built-in wine cooler.

Reason to Buy a Built-in Wine Cooler

wine storage temperatureIn order to store your wines at an ideal temperature for finest aging, you need a wine cooler. However, many homeowners face the challenge of allocating an extra space to place an additional refrigerator despite the fact that many wine coolers are relatively smaller when compared to the ordinary home refrigerators.

Built-in wine refrigerators can be installed under the countertop. Nowadays, these coolers are becoming popular for many wine collectors who want to store their wines in the best possible temperature condition. The refrigerators not only help you to keep wines but also help to regulate and keep out excessive light that can destroy your wines. Unlike the wine coolers, kitchen refrigerators are colder and allow more humidity to enter the unit. Also, those refrigerators are always full of food stuff, and therefore no available extra space to store a few bottles of wine.

However, built-in wine coolers are more expensive than the ordinary refrigerators. They also require more labor during installation but they will become an integrated part of your home. If the kitchen is already overcrowded, the built-in wine coolers will save the space because they are tucked away from the space. Having a built-in wine cooler does not really mean you must be a serious wine collector because even typical wine lovers can enjoy keeping some bottles of wine for friends and guests.

Types of Built-In Wine Refrigerators

Built-in wine refrigerators work based on two types of technologies; thermoelectric and compressor cooling processes.

Thermoelectric Wine Refrigerators

Thermoelectric wine refrigerators use a technology that is quieter compared to their compressor counterparts. Additionally, they utilize less energy. If you are used to noisy appliances in your house, thermoelectric wine refrigerators will not add more trouble to the existing one. However, they are less powerful and therefore not suitable for cooling a large capacity of wine bottles. Sometimes, the under-counter cooler will experience more heat and a thermoelectric cooler may not be able to cool the bottles up to the required temperature condition.

Compressor Wine Refrigerators

Compressor wine refrigerators utilize a similar technology as the kitchen refrigerator. So, they are loud and vibrate vigorously, meaning they use more energy compared to thermoelectric coolers. Even though they consume more energy, they are powerful and can be able to cool a large capacity of wine bottles. During a hot day, they will perform well and consistently. They are perfect for those looking for good excellent performance rather than a quieter wine cooler.

Things to Consider when Buying a New Wine Refrigerator

Apart from deciding whether to buy a thermoelectric or compressor wine cooler, there are other several things to consider.


Ensure you have a place where you will install the new wine cooler. If you consider buying a freestanding model, you will figure out where to place the unit. For the built-in wine coolers, they should be installed in a space under a counter or somewhere it can become a home’s fixture.


Built-in wine refrigerators vary in prices with the cheapest models going for around $3000 while the high-end models cost several thousands of dollars. However, you need to consider what kind of style, size, capacity, and features you want before deciding to buy a particular wine cooler. Remember, installation costs are separate.


storing wineThis is one of the most crucial things to consider before purchasing a wine cooler. If your kitchen is limited on space, you will have to consider a smaller unit. For large kitchens, think about the bottles you want to keep at a given time. It is also advisable to check the size of bottles that can fit comfortably into the cooler because different manufacturers have different bottle sizes. Based on what kind of wine you want to store, choose a cooler that can accommodate them appropriately.

Number of zones

Many built-in wine refrigerators have a single zone, which means all your wines will be stored at a similar temperature. There are larger wine coolers that come with dual storage zones, meaning you can keep different types of wines at different temperature conditions. If you love both red and white wine, it will be advisable to go for a dual zoned wine cooler.


If you only care about capacity, style may not be a factor to consider. For those that want a good looking unit, there are plenty of models to choose from. You can choose a cooler with LED lighting or find wine coolers with different colors. You can as well research on different models to see what interests you most.

Energy usage

Last but not least, a wine refrigerator will use a significant amount of energy. No matter what model you purchase, your energy bills must increase. However, wine coolers use energy differently. If you are looking for a unit that will not consume a lot of energy, thermoelectric coolers are the best option.
