The Basics About Legionnaires’ Disease And HVAC Systems

There is no doubt that HVAC systems bring enormous benefits to homes and buildings across the globe. They not only cool the premises but also help people stay comfortable throughout the day. Their presence enhances productivity and prolongs the life of vital equipment. However, they could also negatively impact air quality if not properly cared for. The health of the occupants may suffer with individuals contracting respiratory diseases. One of the most dangerous is Legionnaires’ Disease.


A Brief History of Legionnaires’ Disease

The bacterium responsible for the disease may have been present for over six decades but it only came to public consciousness in the 1970s when a tragic incident got massive attention. It was 1976 and the American Legion gathered in Philadelphia for their annual convention. Suddenly, 221 of those who attended became sick and doctors could not figure out what was happening. Thirty four of them eventually died which triggered a panic. After the mystery behind the illness was solved, the strain was named after this incident.


Common Signs and Symptoms

Legionnaire’s Disease, also called legionellosis, is a form of pneumonia. Persons who are exposed to the bacteria will experience chills, coughing, high fever, body aches, and a host of other symptoms. As we have seen from the 1976 outbreak, this disease can be fatal and is difficult to cure. The best way to fight it is to prevent it from happening in the first place. The bacterium thrives in warm water that remains stagnant, making cooling towers ideal habitats. They can spread inside an establishment through centralized air conditioning as well as other means.


How the HVAC Industry Can Help

The industry has studied how to prevent a recurrence of the outbreak. Experts have found the weaknesses that made systems of that era vulnerable to the bacterium. Since then, various manufacturers have made changes to their product design and installation protocols. There are also methods of operation and maintenance procedures that help owners avoid this illness from affecting their site. All of these keep people safe from harm.

Surge Protectors And HVAC: What You Need To Know

All electrical appliances suffer from one vulnerability, power surges, which can fry the electrical circuitry of the device and render it inoperable. Modern HVAC equipment use printed circuit boards, which can also be damaged by power surges. There is therefore need for HVAC surge protectors to be installed in the power supply systems of the cooling and heating systems of a home.

Causes of Power Surges

The most common cause of power surges is lightening strikes. The high voltage from lightening can find its way into the grid and any load that is connected to the grid will be affected. The damage may be minor or severe, depending on the types of protective circuits in place. Another cause of power surges is abnormalities in power generation, transmission and distribution systems. While they may be rare, they can cause serious damage to appliances that are connected to the grid. Thirdly, when heavy loads, such as washing machines, electric ovens, water heater and dishwashers are turned off at the same time, there will be a minor power surge in your home’s power supply system. This may damage some appliances, including your air conditioner and heater.

Protecting Your Home Against Power Surges

It is important to note that voltage spikes can emanate from the grid or from your home’s power supply system. To protect your home from power surges emanating from the grid, you may want to consider installing a whole-house surge protector at the main breaker box, or consumer control unit. To protect each electrical appliance from surges resulting from switching off and on of heavy loads, it is crucial that you install individual surge protectors at each electrical outlet where the devices are connected.

Importance of Using HVAC Surge Protectors

Air conditioners contain numerous electrical components, including; compressor pump, thermostat, control system, fans and blowers among others. Each of these components can be damaged during a power surge, hence the need to install surge protectors. These devices are not usually costly, but there are some high-end surge protectors that are very effective. Follow us for more great articles on heating, air conditioning and home needs.

What Are The Different Kinds Of Air Conditioning Systems?

As spring pushes winter into the rear view mirror, the promise of warmer temperatures means summer will be rushing in soon. While there might be a month and some change before you need to make the full switch over, it won’t be long before the cold of winter is a distant memory and one heatwave after another batters us with 90 and 100 degree temperatures. There’s no question about it: air conditioning weather is coming!

There are several different air conditioner types, and which one works best for you varies depending on your home, your budget, and what your specific needs are.

Central Air Conditioning
Central air is the most efficient and generally the most effective air conditioning system for a home or apartment complex. In most cases, at least when it comes to apartments, central air conditioning will be either installed, or not even an option.

When it comes to setting up a central air conditioning unit in your own house, this is often the most expensive option but it can create a system that easily cools every room in the house, allowing for a comfortable summer experience no matter how hot it gets outside.

Window Air Conditioning Units
Window air conditioners are among the most common options. This air conditioning type is easy to buy and is stuck in a window. A good unit can make one room incredible comfortable, or in a one story home will often be enough to make the entire floor extremely comfortable. Air units are made by a variety of companies and the price range can go from a few hundred bucks to a few thousand for high end models.

Portable Air Conditioners
Portable air conditioning units are an inexpensive option compared to most window units and come in both residential and commercial sizes and setups. Portable air conditioning units are fantastic for small apartments, bungalows, or single bedrooms in a home. Make sure to grab a portable air conditioner and not a portable air cooler, as the first one tends to work much better.

Ways To Increase Your Air Conditioner’s Efficiency

There are many ways to increase air conditioning efficiency; some will cost you some money while others will not cost you anything. Replacing your filters and hiring a heating and cooling company to clean your air ducts will cost you some money, but the following methods will not cost you a single dime.

Plugging Air Duct Leaks

If you have a central HVAC system, whether high velocity or low velocity, you need to check the ductwork for holes and gaps between joints. Use duct sealing tape to plug any leaks. This will ensure that heat energy is not lost while being transported to different parts of the house.

Clean the Condenser Unit

The condenser unit of an air conditioning system is normally located outside. This means that leaves and twigs, among other types of debris, may settle on the unit, covering it and causing disruption to air flow in the unit. As a result, the fan’s motor will be forced to work a little bit harder to push air through the condenser coil. A simple way of increasing air conditioning efficiency is to clear the debris and clean the unit to ensure unrestricted air flow.

Keep Heat Sources Away

Air conditioners have thermostats, which are responsible for turning the device on when the room needs cooling, and off when the room is sufficiently cooled. If you put a heat source, like an iron box, near the thermostat, cooling will continue to take place even if the temperature of the room is already cool. For this reason, any item that emits heat should be kept away from the AC thermostat to improve air conditioning efficiency.

Clean Air Filters

If you are able to open the AC unit, you can remove air filters and clean them to get rid of dirt. Clogged filters usually overwork the system forcing it to consume more power to push air through the clogged passageway. Alternatively, you can replace the filter, but this will cost you some money.

With these few tips on improving air conditioner efficiency, cutting down on utility bills is a reality, even for the average homeowner. Call us for all heating and air conditioning needs.

5 Home Cooling Myths

There’s nothing more exciting than enjoying the cool breeze from your AC unit during summer. On the other hand, not many people like the fact that energy bills often go higher when the weather is hot. In order to save money, there are lots of practices that people do to keep their houses cool. Perhaps you’re also doing some of these things, but the bottom line is, not all of these practices are true. If you want to distinguish cooling facts from cooling myths, you may read the article through and take note of these debunked beliefs.

Keeping Your Fan Turned On Will Make the Room Cooler

Many people think that in order to save on AC operating costs, they should keep their electric fans on even if they are outside. Honestly, fans don’t make rooms cooler. They only help circulate the air, which makes people feel the air on various areas of skin. As this happens, the body temperature goes lower, so it’s easy to think that the fan makes the room cooler.

Leaving the Fan On Will Help Me Save Energy

Leaving the fan on will not help you save on electricity bills, but will actually consume more energy so you have to pay more. Your air conditioner will consume the same amount of power whether your fan is on or not. It’s best not to use your fan if you’re happy with the temperature inside your room. The only exception to this myth is when the temperature outside is way too hot and you place the fan near the window, the air coming out of the fan can help prevent the hot air from entering the cold room.

A Bigger Air Conditioner Will Make Your Room Cool Faster

Keeping your room cool and comfy does not only depend on the size of your air conditioner. It is important that you get the right size of air conditioner to match the size of your room because this will help you save a lot of energy. Another thing that you need to check is how sealed your room is. Leaks can cause the cold air to escape, so make sure that all cracks and openings are sealed before turning your AC unit on.

Putting the Temperature Setting As Low As You Can Will Cool the Room Faster

Doing this won’t cool the room faster. AC units have thermostats that will automatically switch off once the desired setting is achieved. Cranking the temperature nob to the lowest and changing it often may only break the thermostat control and waste a lot of energy.

It’s Okay Not to Clean My Air Conditioner As Long As the Room Gets Cold

You need to clean your AC unit, even if it seems to work fine. In time, your machine will have a hard time producing cold air if the filter, fan blades and coils are dusty. If you are unable to clean your air conditioner, you can contact experts to help you out to ensure that your unit runs properly for a long time.

Carbon Monoxide Myths And Facts

Many people are victims of carbon monoxide poisoning, but most people do not have enough knowledge about it. Since carbon monoxide is found in fire and smoke, many think that it can be easily seen or detected. Below are some carbon monoxide myths and facts that will help you know how to properly deal with CO-related issues.

Some say that you can smell or taste CO, so it’s easy to tell when there’s carbon monoxide leak in your home. Is this true?

Carbon monoxide is invisible, odorless and definitely tasteless. When people say that they smell carbon monoxide leaking from somewhere, they actually smell other elements of the fuel that are burnt. These elements may sometimes cause unpleasant tastes in people’s mouths, but they absolutely do not and cannot savor CO.

There are folks claiming that carbon monoxide alarms are only sold in the market for business reasons as they are not effective at all. Is there any truth to this?

Just like any product in the market, carbon monoxide alarms have gone through testing phases. Earlier versions of carbon monoxide alarms may not have been very accurate, but those old models are now replaced by advanced models today that are more precise and useful. It is vital for buildings and homes to have carbon monoxide alarms since CO cannot be seen, tasted or sensed by humans easily.

Carbon monoxide can’t kill you because there are more pollutants in the environment and yet people are still alive. Why are many people very scared about CO poisoning?

Inhaling large amounts of carbon monoxide can be fatal. An enclosed space filled with carbon monoxide can harm people faster because there are no other sources of clean air, thus, the people inside have no option but to inhale CO. Some experts label carbon monoxide as a silent killer because it is invisible and its presence cannot be detected right there and then. A person who breathes in carbon monoxide fills in his lungs with this type of gas instead of oxygen. As the hemoglobin binds with CO instead of oxygen, the body suffers from hypoxia, which can lead to unconsciousness, organ damage and slow death.

Carbon monoxide poisoning should not be treated lightly. All property owners should see to it that their HVAC machines are regularly maintained to prevent CO leaks. For further information and assistance on CO poisoning, it’s best to contact experts. Call us for all of your heating and air conditioning needs and we will provide you the best services as soon possible.

Reasons To Change Your Air Filter Regularly

The primary purpose of practicing proper air filter maintenance is to keep your home clean and comfortable. While it is convenient for you to wipe stains and dust off your couch, your bed or your dining table, it is a lot more difficult to remove invisible air pollutants. These air pollutants are present in the air inside your home and are harmful to the health of your loved ones. HVAC experts say that the best solution for this is to change your air filter regularly.

Why should you have proper air filter maintenance?

1.) To prolong the life of your HVAC unit.

A clogged up air filter causes severe damage to your unit. Since it cannot do its job of cleaning the air before it enters the system, dust and dirt can accumulate and make their way into the coils, fans and motor. When your unit malfunctions, you have to spend thousands of dollars on repair work and parts replacement. Simply changing your air filter every three to four months is enough to ensure that your unit will last you many years of use.

2.) To ensure good indoor air quality.

When you have a clean air filter, it means that you are preventing pollen, dust mites, dust and other pollutants from being circulated inside your home. With a fully functioning HVAC unit, your family will have fresh, healthy and clean air to breathe.

3.) To save on your electricity bill.

A poorly maintained HVAC unit would need about 15 percent more energy to circulate air inside your home. This means that it would eat up more electricity to be able to do its job. The more electricity it needs, the more you are going to spend on your utilities. By keeping your air filter clean, you will be able to save up to 15 percent on your electricity bill every month.

Changing your filter regularly is extremely important. It helps ensure that you are breathing in excellent indoor air quality and it helps you save on your electricity cost. Moreover, proper maintenance also helps prolong the life of your HVAC unit. Call us today and we will provide you with all your HVAC maintenance needs.

Why HVAC Maintenance Is Important

Many people invest a lot of money in their HVAC system, but they do not take the time to make sure it receives the proper maintenance. Regular maintenance is necessary for keeping your system functioning without any problems. Below is a list of additional reasons HVAC maintenance is important:

Lower Your Utility Bills

Saving money is one of the top reasons people should maintain their HVAC system. If your HVAC system is functioning properly, you will be able to save money on your energy bill. HVAC maintenance also helps prevent the need for major repairs or replacement.

Healthy Air

A properly functioning HVAC not only keeps your home comfortable, but it also helps keep the air clean. Clean coils and filters make it easier for the whole family to breathe. On the other hand, a poorly-maintained HVAC system can be a breeding ground for bacteria and mold. This can worsen respiratory problems.

Life Of The System

A HVAC system that receives the proper maintenance will last much longer. In fact, a HVAC system can potentially last over 10 years with maintenance. Replacing a unit can be quite expensive, so it makes sense to try to keep yours as long as you can.

Fewer Emergency Repairs

Most HVAC units will require emergency repairs at some point. However, a well-maintained system is much less likely to need emergency repairs.

Parts Under Warranty

If your HVAC system is in need of repair, and the component or part is still under warranty, you may be able to get it repaired for little or no cost. This is why it is important to have the part inspected before the warranty expires.


A poorly-maintained HVAC system has to work 20 percent harder in order to do the same amount of work. If your HVAC system is well-maintained, it will be able to use less energy to cool or heat the home. This means the unit will suffer less wear and tear.

Keeping your HVAC system maintained can help you save time, money and extend the life of your unit. Call us to schedule your HVAC maintenance checkup today.

3 FAQs For Home Heating, Ventilation And Water Heaters

Most furnaces are designed to automatically shut down when the air in your home is comfortable. In most cases, you won’t even realize when this process takes place. However, if your system keeps turning on and off constantly, it could mean that something is wrong. Before you get all worried, you can try some of these troubleshooting tips before calling a professional. Here are some frequently asked questions about heating systems.

Why does my heater keep shutting off?

Your furnace will usually turn on and off as a result of something called “short cycling”. This basically refers to problems within your system. When short cycling is left unattended for an extended period of time, it usually leads to break down or higher energy bills. When troubleshooting your furnace for short cycling, the first thing you should do is check the air filters. Air filters wear off after a while, and will require cleaning or replacing if your system is to resume normal function,

The next step will be to check your thermostat. A faulty thermostat can cause short cycling. Make sure your thermostat has the right settings and that it is switched on. In some cases, placement of the thermostat can affect normal operations. For instance, if the thermostat is comes in direct contact with another source of heat, such as sunlight, it might assume your home is too warm and shut down.

Other causes of short cycling may include; presence of debris in air vents or chimney, improper sizing of heating system or corrosion on flame sensors.

How are Heaters Rated?

AFUE or Annual Fuel Utilization Efficiency is the measurement used to rate how efficient heaters are. The higher the AFUE rating, the more efficient the heater is. A higher rating means that your heater will not only serve you better for an extended period of time, but will also save you money on utility bills.

Why is it that My Heat Pump Never Shuts Off?

If your heat pump remains on even in the hottest of seasons, then you should probably consult a professional. But before you do that, you can try troubleshooting it yourself. Make sure the thermostat is placed correctly and the outdoor unit is operating normally. You should also check whether the air filter is clean and that all doors and windows are closed when this problem arises.
