How Does The Office Temperature Effect Your Productivity?

You may be surprised to learn that the efficiency and performance of a commercial HVAC system can have a lot to do with a company’s overall productivity. Numerous studies have yield varying results when trying to determine the ideal office temperature to optimize productivity. The of studies majority find that between 70 and 73 degrees (Fahrenheit) is the best temperature to boost employee productivity.

Dialing in your office thermostat to an optimal temperature is actually more difficult than it sounds. Each individual working in the office has an opinion about what optimal temperature is. Body mass index describes how much body fat a person has. An individual with a low BMI usually gets cold easier while a person with a high BMI is more sensitive to heat. Age is also a factor because older people are more affected by cold. Most people are naturally more comfortable at warmer temperatures during the summer and colder temperatures during the winter because they are predisposed to expecting certain kinds of weather at certain times of the year.

Clothing affects how people are affected by ambient temperature. During the spring and summer, people tend to wear clothing made with thin fabrics that breathe. During the winter, wardrobes consist of heavy sweaters and coats made of materials designed to insulate the body.

You also need to think about controlling humidity in the work environment. It does you no good to set the temperature at a comfortable level if the humidity level is much higher or lower than 40 percent. Condensing air conditioners typically remove moisture from the air. During the winter, running the HVAC system can reduce the humidity level below a comfortable point. When this happens, your nasal passages, throat and skin dry out and it feels colder than it actually is.

Creating a comfortable work environment for your employees will pay off with increased productivity and a positive effect on the bottom line. Providing your commercial HVAC system with regular maintenance and service will ensure that it works at peak performance year round.

The Basics About Legionnaires’ Disease And HVAC Systems

HVAC systems have long been known to be a major culprit in the spread of Legionnaires’ disease. Anyone working in the HVAC industry should be familiar with this very important topic, and learn what they can do to help prevent this very serious disease.

Legionnaires’ disease, or Legionellosis, is caused by the bacterium Legionella pneumophelia. This bacterium is a particular type of pneumonia that can result in people developing coughs, aches, chills, fever, in addition to a variety of other serious symptoms. The L. pneumophelia bacterium has been traced back to the 1960’s; however, in 1976, when 221 attendees at an American Legion convention in Philadelphia became ill, resulting in the death of 34 people, scientists began researching the cause of the disease. Finally, in 1976, the bacterium was identified and named.

Legionnaires’ disease is most commonly found in air conditioning systems and cooling towers, but can also be present in shower heads, hot tubs and other elements. Warm stagnant water in HVAC systems can provide the ideal environment for the bacterium to grow. When central HVAC systems are used, the bacterium is then dispersed into the air. Of course, with the bacterium airborne, people are exposed to it simply by being in the building and breathing the contaminated air.

While Legionnaires’ disease is often effectively treated with antibiotics, up to 30% of the people who contract this disease will die from it. The CDC reports that approximately 18,000 U.S. citizens are hospitalized each year with Legionnaires’ disease. Clearly, the best course of action is to prevent the disease rather than react to the disease once people become sick.

There have been numerous outbreaks of Legionnaire’s disease since 1976 and many of these cases have been traced to an HVAC system. Europe has implemented what they call, “Approved Code of Practice and Guidance L8” as a means of trying to effectively prevent Legionnaire’s disease. It is clear that prevention requires managing all phases of the HVAC system. From initial design and installation to proper operation and routine maintenance, focusing on HVAC systems can help prevent Legionnaire’s disease.

Should I Leave Interior Doors Open Or Closed During Heating And Cooling?

In multi-roomed buildings, closing interior doors during heating and or cooling is lowers energy efficiency. All HVAC equipment, whether heaters or air conditioners, have fans that blow air around in massive quantities; 1000-2000 cubic meters per minute. Open interior doors enable the fan-moved air to circulate without restrictions but closed interior doors inhibit air flow, pressurizing the rooms.

Increased energy efficiency from open interior doors

Increasing pressure cannot be contained, and the already conditioned air is forced out of a room through holes, slits, and other openings in order to relieve the pressure. However, since the doors are still closed (limiting air circulation space), and the heating/ cooling equipments are still running, the rooms remain pressurized. In pressurized rooms, the vacuum created by expelled air is replaced with outdoor air that is sucked into the building through fire flues and other unobstructed openings.

Reduced energy efficiency

In closed doors rooms, conditioned air is wasted through the forceful eviction of air that results from the pressurization of the rooms, and this means that HVAC systems have to restart the air conditioning process all over. Since optimum indoor air quality (IAQ) is not achieved, the excessive heat, cold and moisture form conducive conditions for the growth, circulation, and increment of pathogens such as mold, bacteria, and mites. The elimination of these pollutants requires additional costs invested in elimination equipment, as well as the energy required to run those equipments. A re-run of an HVAC equipment translates to additional energy consumption.

It is to be noted that the expulsion of conditioned air is not the only problem that forces HVAC systems to run longer than necessary to condition air. External air that gets sucked into a room is not conditioned; it is full of pollutants and extreme temperatures. HVAC systems are forced to run longer and consume additional energy in order to condition (purify, cool or heat) the new air in order to ensure that the quality of indoor air is as pure, warm or cool as the building occupants require.

Since it is not possible for every building/ occupant to leave his/ her interior doors open all the time, people should apply any of the following energy efficiency tips. First, construction of buildings should put into consideration the need for pressure relievers. Gaps can be left above or below doors, and transfer grills can be installed on room-dividing walls. Alternatively, and whenever possible, building occupants/ owners should purchase HVAC systems that have return air ducts.

The Science Behind How Air Conditioners Work

Air conditioners are probably one of the greatest inventions on earth. They make our surroundings cooler, and our work and home environments more comfortable. It is certainly worth knowing how air conditioners work.

Air conditioners utilize chemicals called refrigerants which quickly convert gas to liquid at low temperatures. These compounds continuously evaporate and condense within the coils of the unit. The refrigerants, along with the fans, ducts, and vents in the system, move and transfer air from the inside to the outside.

Basically, a conventional air conditioner is equipped with these main parts: a compressor, a condenser and an evaporator. The set-up and processes involved are essentially the same and may differ slightly because of the different air conditioning variations. The first step involves the chemical compounds which reaches the compressor as a low-pressure, cool gas. As its name suggests, the compressor, which is a large electric pump, compresses the gas. This exerts pressure on the gas and as a consequence, the molecules are packed closer together, resulting in high energy and temperature.

This high pressure, hot gas then makes its way into the condenser which facilitates the transfer of heat and changes the gas to cool liquid. The liquid flows into the evaporator. The evaporator acts as the receptacle or container of the liquid refrigerant and transforms the liquid into gas. It is at this stage when heat is extracted from the surrounding air and cool gas is produced.

Air conditioners have fans that circulate and blow air from the inside to the outside. Cold air is denser than hot air; thus, hot air rises and cold air sinks. To address this, the machines also have vents to draw the air down into ducts, continuously removing the hot air and keeping the air cool. The entire process is repeated all over again until such time the room is at the preferred temperature.

This modern day machinery is indeed a result of the brilliant exploitation of the wonders of science — a combination of physical law and chemistry. For air conditioning and heating needs, do not hesitate to give us a call.

What Do UV Lights Really Do For Your Indoor Air Quality?

People who suffer from allergies and asthma have sealed their homes for years in order to keep outdoor air pollution from contaminating their indoor breathing air. They dust more and keep their windows closed to limit spores and allergens that aggravate their breathing problems. The Environmental Protection Agency has released recent information, though, that informs us that indoor air quality has actually reached higher levels of pollution that outdoor air quality levels.

The amount of fungi, bacteria, viruses, mold and other micro-organisms growing in homes are increasing and their spread is on the rise. This growth results in part from the way today’s houses are insulated to keep air in when they are built and how air flow patterns are created through them. According to the U. S. National Library of Medicine, these pollutants in indoor air plus in and on HVAC surfaces such as insulation, ductwork, drain pans, air vents and filters are harmful and pose several health risks for the homes’ inhabitants.

An environmentally safe and friendly solution is available in the form of UV Lights. UV Lights help because they produce ultraviolet radiation that destroys a great many of these air pollutants. Installing germicidal UV lights will break down the RNA and DNA of these micro-organisms, getting rid of them in upper-room air and playing a major role in prevention of secondary allergies. An in-duct ultraviolet germicidal irradiation system that uses short UV waves; or a germicidal ultraviolet air disinfection system using lamps directly shining onto the heat pump or A/C evaporator coils or lamps in the ductwork also kill many of the fungi, mold and viruses where they grow. Painting these surfaces with a catalyst solution that reacts to the ultraviolet rays from the lights converts germs to substances that are harmless. The EPA highly recommends this process because it greatly reduces indoor air pollution.

Because many studies show that germicidal UV Lights are very effective in breaking down polluting organisms in homes, they play a major role in reducing allergy suffering and controlling the micro-organisms that aggravate asthma. Many airborne pollutants and pathogens can be removed by a homeowner’s use of germicidal UV Lights and air disinfection systems to clean up polluted inside air.

Temperature Control Tips & Tricks For HVAC Systems

Just like any other machine or device, HVAC systems wear and tear over time. Therefore, it is up to the owner to schedule regular professional checkups and use good practices when operating the HVAC system. A well maintained air conditioning system lasts for long and operates efficiently. So, to get the best out of a HVAC system, one has to know some of the HVAC tips and tricks.

Maintaining Filters

The air filters have to be cleaned every month so as to enable smooth flow of air in and out of the HVAC system. If the filters cannot be cleaned, the owner should replace them with new ones. There are many types of filters available in the market. However, the recommended ones are electrostatic filters. Cleaning the filters might not be a straightforward thing to a rookie. So, it is advisable to check the user manual for instructions.

Cleaning Condenser Unit

The smooth-running of the condenser unit plays a huge role in ensuring efficient operation of the HVAC system. Therefore, the owner should remove leaves and debris that has settled on the outdoor condenser unit. The condenser fans must also be kept running efficiently. This is done by cleaning the fan blades and coils before the cold seasons.

Clearing Vegetation

All vegetation that is close to outdoor HVAC units should be cleared. There should be a clearance of about 2 feet between the vegetation and the HVAC units. This keeps the fan grill clean at most times.


Since HVAC systems have moving parts, i.e. motors, the owner should lubricate them at least once a year. This is applicable to HVAC systems that have oil ports. For those that do not have oil ports, it is advisable to let a professional do the oiling. When lubricating the HVAC system, one should use non-detergent lightweight SAE 20 oil. Also he or she should not add more than 10 drops per port.

Those are some of the few HVAC tips and tricks that can be used to optimize the operation of HVAC systems. You must know them so as properly maintain your system. Moreover feel free to call us for all of your heating and air conditioning needs if at all you need a professional.

What Size HVAC System Should I Have

Choosing the central AC system for installation for your house’s HVAC is not straightforward. There are several physical factors pertaining to your house’s cooling that could directly influence the efficiency, performance quality, and costs of the air conditioning system. You should also look into the different air conditioning system varieties available, taking into account their efficiency, size, and installation needs.

The Cooling Cycle

Central ACs use a condenser coil and compressor housed in an external unit, and an evaporator and expansion valve mounted over the furnace heater within the HVAC system of your home. Air conditioning basically works by converting gas to liquid and reversing the process with the help of pressure. The refrigerant gets started with this cycle as a low-temperature, low-pressure gas. It moves into the external unit where it is initially compressed into a high-temperature, high-pressure gas. Then it steps into the coil where the gas is cooled by the fan to take shape of a high-pressure liquid. The refrigerant in the liquid form flows via the tubing inside the house to the HVAC system. It there enters the valve for expansion that restricts the liquid flow while entering the evaporator. The valve allows the liquid to expand within the coil.

The refrigerant later goes back to the external unit in the form of a low-pressure, low-temperature gas to restart the cycle. The air is cooled via exposure to the chilled coil, and is later circulated across the home. The air conditioning system runs continuously until it hits the desired temperature. Any form of humidity in the air condenses and embraces the coil in the form of water and dribbles into a distillation pan. This is how the central AC system both dehumidifies and cools your residence.

HVAC System Sizes

The right air conditioner size is key to installing a home cooling setup. Sizing an AC warrants a formal interaction with an expert consultant who’d look into the aspects that effect the house’s cooling.

Since air conditioning can be the most critical and expensive appliances you may own, it’s extremely important to have a trained professional take care of all the technical aspects. If you are looking for a reliable and experienced team of professionals to handle your HVAC needs, give us a call.

What Is The Difference Between Electric Heat Pumps And Furnaces?

The difference between electric heat pumps and gas furnaces has always been a source of confusion for many wanting to buy one of the appliances. The main difference between the two is that a furnace blows warm heated air throughout your premises, while a heat pump uses a refrigerant to either heat or cool air.

Making the choice between the two is dependent on several factors such as location. If you live in a relatively cold climate, a furnace may be the most viable option. However, people who live in warm areas are likely to benefit from cost effectiveness by buying heat pumps. It’s more of a personal choice but the right kind of information can help you choose the most suitable option.


Heat pumps have proved to be more efficient than furnaces. In fact, they can achieve about 30 -40 percent more energy efficiency as compared to gas furnaces. Heat pumps simply move and don’t generate heat enabling them to provide up to four times more energy than they consume. However, their efficiency is significantly reduced when there are huge temperature differences, especially in cold winters. One way to increase the efficiency of your heat pump is to ensure it is of the appropriate size for your premises. However, it is also important to size your furnace correctly to maximize its efficiency.


When it comes to cost, there are several determining factors you should consider before choosing to buy an electric pump or a gas furnace. Start by finding out the difference in gas and electricity prices in your area. The cost of the units also matters. Depending on your climate, a heat pump can heat and cool your premises all year round. If you choose a gas furnace, you may also need to buy an air conditioner to cool your premises in the warmer months.


In as much as heat pumps eliminate the need to invest in an additional appliance (an air conditioner) they use outdoor heat to warm your home. This means that they may not be as effective as a gas furnace if you live in a very cold area. A heat pump is more appropriate for moderate climate areas.

With the differences outlined above, choosing the most appropriate appliance should be easy. Call us for all your heating and furnace needs.
