Warm air heating systems are a popular heating and air conditioning option for most homes. They heat the air by using oil, electricity, or natural gas in a furnace. The air is then distributed throughout the home out of ductwork that spread out across the floor and ceilings and is then blown out in vents, registers, and wall or ceiling supplies to control the temperature of a particular area. The cycle is pretty straightforward but there are a few nuances which could help you understand issues that can arise from this particular system. Read more
“It started as a nagging headache,” Diane said. “And then it became worse before turning into a horror show.”
It was around 9 pm on a cold December night and both of them were sitting in front of their fireplace, decompressing from the hard day’s work. The baby June was in her crib. Suddenly, Liam, Diane’s husband, became sick – headache, vomiting, the works. That made Diane concerned for her husband’s health but she chalked it up to the bug that was going around the neighborhood. “Must be the flu.”
Two hours later, Diane felt her heart thudding in her chest, wanting to come out. She became nauseous and lightheaded, and her whole body went cold. She panicked and rushed to “Google” the symptoms – finding it just might be Carbon Monoxide poisoning. She called 911 after finding out that they were indeed being poisoned by the stealthiest killer: Carbon Monoxide.
Her family was saved thanks to Diane’s quick reaction and pure timing but, everyone is not so lucky.
What is Carbon Monoxide?
CO is a colorless, tasteless, and odorless gas. That means between 1999 to 2010 most of the 5,149 Americans that ended up in graves because of non-fire-related Carbon Monoxide poisoning had no idea what hit them. No bad odor, no horrible taste, nothing – except for the untimely death.
Although, like all accidents you can minimize the chances of dying from CO, most people avoid taking the right precautionary measures until it happens to them. When, unfortunately, it is already too late. And the damage is done.
CO is produced any time you burn fossil fuels like in cars, trucks, fireplaces, and good old furnaces. Everyone is at risk regardless of gender or age, but children and elderly and those with preexisting diseases of heart or lungs are at higher risk of developing complications such as permanent brain damage, life-threatening heart complications, and death.
How Does Carbon Monoxide Affect Our Health?
Once inhaled, it goes into the blood stream and displaces oxygen from hemoglobin, that results in a deficiency of oxygen which leads to hypoxia and eventually death.
The symptoms of CO are non-specific and often don’t tell anything by themselves. Most common symptoms include altered mental status, headache, nausea, weakness and chest pain.
Fortunately, science has made it really easy to prevent against CO exposure. Take steps to prevent accidental exposure to Carbon Monoxide. Because it is real. And it kills.
How to Avoid Carbon Monoxide Poisoning
Here are just a few ways that you can avoid carbon monoxide poisoning:
1. Install and maintain a CO detector: This is the single most important thing you can do to protect your family against the possibility of Carbon Monoxide poisoning. Make sure to buy a battery operated detector with a loud enough alarm to wake you up. But that’s not all, replace the battery every year and change the detector once every 5 years.
2. Don’t use portable gas camp stoves indoors. Small appliances like these also contribute to the buildup of Carbon Monoxide and when indoors, the harmful gasses can’t escape and your family can’t escape from them. Get rid of them folks.
3. Get your gas appliances checked by an expert. Make sure that they are working correctly and all the stuff that is supposed to be inside is staying inside and not spilling out to kill you when you’re asleep.
4. Never ignore any unusual odor coming from your refrigerator. CO itself has no odor, but in this case, other gasses mixed with CO have a particular odor that might give it away.
5. Clean your chimney. Debris can clog up your chimney real bad. So, now all the gasses would accumulate inside your living room instead of escaping through the chimney. Get your chimney cleaned before it cleans you.
6. Be smart. Don’t burn charcoal indoors, use generators inside of your home or basement, or patch a vent pipe with chewing gum. We’ve seen it all and it’s always dangerous.
One last thing, if you ever suspect that you or a family member has been exposed to Carbon Monoxide, immediately evacuate the house and call 911.

Selecting a Water Heater
Over the last several years new advances in water heating technology have given the consumer many more choices than even just a short time ago. New heaters are more efficient, keep water at temperature longer, are quieter, and can save you lots of money over the life of the heater.
There are a few things you will want to keep in mind when choosing a water heater.
- The size of your home
- Hot water needs
- Geographic location
Home size and budget are going to be your two major concerns followed by your hot water needs and geographic location.
Types of Water Heater
The most basic type of heater that everyone is familiar with is the tank-style of water heater. These are among the least-efficient options in heating water, however they are the least-expensive and they have gotten more efficient than they have been in the past. They will provide a lot of hot water over a long period of time.
One option for people in the sunnier parts of the US is solar. Solar is exactly as it sounds and will use the sun’s energy to heat water. Their downsides are weather, cost, and need for a supplemental water heater. The initial cost of these can be high and you will also need another water heater to help out when the sun isn’t out.
Inline water heaters are a new style of heater that has become popular over the last few years. They are among the most efficient systems however their initial cost can be a little high. Inline heaters only heat the water as it is passing through the unit itself. This saves a lot on heating costs however you may need to have more than one, which will raise the initial costs.
You can think of heat pump water heaters as something like a reverse air conditioner for your water. Very much like your ac run in reverse, these systems heat by moving heat energy from one area to the desired area. They are very efficient however to operate best they will need to be placed in an area that has fairly steady temperatures and won’t get too cold.

If you suffer from allergies, you know their symptoms can make life miserable. Obviously you’d be interested in anything that can bring you relief, and that’s why you may want to seriously consider buying at humidifier for your home.
What Is a Humidifier and How Does it Work?
Humidifiers are electrically-powered machines that use various methods to turn liquid water into vapor. The vapor is spread across adjacent rooms, moisturizing the air and raising relative indoor humidity in the process. Humidifiers are commonly employed during the winter time in cold climates, where excessive dryness of the air is a constant problem, and all year round in arid or desert climates where the air is chronically lacking in moisture.
Point-of-use humidifiers are portable devices that can be moved from room to room and are generally appropriate for any house or apartment. But another type of unit, known as a whole-house humidifier, disperses much larger quantities of moisturized air from a centralized location. Whole-house humidifiers are used in both commercial and residential settings.
How Do Humidifiers Help Reduce Allergy Symptoms?
Allergy attacks can dry out the throat or nasal linings even as they clog sinuses. Excessively dry air will only exacerbate the trouble, making this type of allergic reaction more severe than it otherwise might be.
Boosting indoor humidity can help eliminate most of this unpleasant dryness, and humidifiers are extremely efficient at doing this. Good-quality units usually include a control device called a hygrometer, and if you set it to produce relative indoor humidity of somewhere between 40 and 49 percent it should bring you almost instant relief. Colds and the flu often manifest in the same way as allergies, so humidifiers can also make you feel better when you’re sick.
Some allergies cause rashes or itchiness, which is also related to excessive dryness (of the skin in this case). People who suffer from eczema also experience much more intense and frequent outbreaks of this disorder when the air is dry. But higher humidity levels works as a remedy to skin allergies and eczema; comfortably humid air can moisturize the skin even more effectively than many over-the-counter topical creams designed to treat dry skin conditions.
One word of caution: if you let your indoor humidity get too high (50 percent or more), it can encourage the breeding of dust mites and the growth of mold, both of which are frequently responsible for allergic reactions. When using a humidifier for allergy relief you have to be careful not to overdo it.
Common Types of Humidifier
Evaporative humidifiers rely on the forces of nature (evaporation, in other words) to moisturize a home’s air gradually, while vaporizing humidifiers use an extra energy input to convert water directly to steam. Point-of-use and whole-house units both require the regular replenishment of water supplies in order to keep functioning, as do impeller and ultrasonic humidifiers, a couple of other options you may want to investigate.

Theoretically a water heater should rust out from the inside in a matter of months. But this doesn’t happen thanks to water heater anodes, the “secret ingredient” that keeps water heaters up and running and virtually rust-free throughout their existence.
Water Heater Anodes 101
Water heater anodes, which are more commonly known as sacrificial anodes, are long rods of magnesium or aluminum wrapped around a steel wire core. When placed inside a water tank they will gradually corrode and would eventually rust down to nothing if not replaced within two or three years. Because the sacrificial anode rusts away the steel interior of the tank remains untouched, and it will stay that way as long as new sacrificial anodes are added as needed.
It is a basic principle of science— when two metals are in contact inside a watery solution they will not rust at the same time. Instead, whichever one is more reactive (prone to rusting) will corrode away completely before the second metal is touched. As it happens magnesium and aluminum are both far more reactive than steel, and that is the secret to the sacrificial anode’s success.
Water Heater Anode Options
Sacrificial anodes come in one of two models. Hex-head anodes screw in at the tank and extend down into the water, while combo anodes are an integrated component of the hot-water delivery assembly, extending into the tank through the hot water outlet. Water heaters are generally sold with either a hex-head anode exclusively or with one anode of each type, which explains why some new heaters are sold with six-year warranties and others with 12-year guarantees (two sacrificial anodes are twice as effective as one).
For those who prefer an option that will keep on working continuously and without degredation, a powered anode can be used in lieu of the sacrificial type. This version of the protective anode is powered by electricity and stops interior tank corrosion by releasing a small but continuous flow of electric current into the water. This interrupts the electrochemical reaction that normally causes metallic corrosion.
Because it never rusts at all a powered anode can last indefinitely. Of course it is a far more expensive than the traditional option, generally running in the $250 range (a conventional sacrificial anode will cost from $40 to $75).
Magnesium sacrificial anodes are more common now than the aluminum versions. As it rusts aluminum leaves behind significant waste product that can clog water pipes and fill tank bottoms with nasty gunky sediment, which can threates a water heater’s long-term survival. Aluminum anodes also swell a bit as they rust and at times can be incredibly difficult to remove.
Meanwhile powered anodes have great utility when water is highly soft. Soft water is more corrosive than hard and will tend to wear out sacrificial anodes so frequently they’re no longer a cost-effective choice. Powered anodes will also kill bacteria that can infect water heater tanks and create terrible odors that follow the water wherever it flows.
Making a Change
Homeowners and landlords should remove sacrificial anodes from water heater tanks at least once per year to check for excessive wear and tear (this is an easy task, all that’s required is an adjustable wrench). If several inches of the steel wire core is visible too much corrosion has taken place and it’s time to get a new anode.
Water heater anodes are not automatically interchangeable, so anyone who needs to buy a new one should check with the dealer or the manufacturer first to find out which anodes are compatible with their heater.

Water heaters are often taken for granted. They work tirelessly 24 hours a day seven days a week. Most people tend to ignore the pops, hisses and small drips that an old or damaged water heater may make as long as they still have hot water. Ignoring or not recognizing the signs of a faulty or poorly working water heater can lead to higher energy cost and a lot of unnecessary stress and inconvenience. Here are a few signs to look for to help you decide if you need a water heater replacement.
Have a look
A visual inspection of the area around your water heater can reveal any problems that may require a replacement. Puddles around your water heater may indicate a severe leak. Also, look for streams of water that lead to a floor drain.
Take a closer look
After inspecting the area around your water heater, take a closer look at valves, fittings, and pipes. A water heater has few moving parts, so any problems can be quickly diagnosed. Some parts can be replaced relatively cheap, but if there is significant corrosion on the tank due to water exposure, then it should be replaced.
Check the age
If you happen to be moving into a new home, find out how old the water heater is before you close the deal. Any water heater over 10 years old should be replaced. A water can last quite a while after its warranty, but its efficiency will be reduced. Also, replacing an older water heater with a newer, more efficient one will save on energy cost.
Measure hot water time
If you discover that you have been running out of hot water a lot faster than you used to, then you may need a new tank.
Metal and water really do not get along well together. After time, minerals in the water will react with the metal and corrosion will occur. Sooner or later you will have to replace your tank even if it appears to be fine on the outside or you still get a decent supply of hot water. The heater could still have damage that reduces efficiency. Don’t wait until a leak occurs or you no longer have hot water to replace your heater, and always seek out a professional for advice and installation. Continue to follow us for more tips and information on how to keep all your heating and cooling systems working perfectly.
Most of the time the cause of water heater problems is revealed with little or no troubleshooting. For instance, if your heater is not heating the water, there is a leak around the heater or it makes a strange gurgling or popping sound when opened, its evident that there is something wrong with your water heater. Gas utility companies will normally makes a free house call if the problem has to do with supply of gas to the tank or the gas water heater’s burner, but you are on your own when it comes to other problems with the water heater. So you should do yourself a favor and learn as much about solving basic water heater problems as you can. For those intricate and technical problems you should definitely call a qualified water heater person to assist you.
One of the most common problems with water heaters is that it doesn’t heat water. In other cases, it either heats the water up too much or doesn’t heat it hot enough. The first and most obvious solution in this case would be to adjust the temperature dial. If this fails to solve the problem, then you should try a few more potential solutions. Usually the culprit when it comes to not enough hot water, is a undersized or small water heater. If you enjoy soaking in the tub and taking long showers you may need to invest in a larger water heater. If you notice that the water is too hot, you should attempt to adjust the temperature dial. Wait a few hours and see if there is a change in the water temperature. If hot water starts shooting out of the faucet,or you can hear the water boiling inside the heater, it could mean that the heater is not switching off at its required or set temperature.
There are many ways in which you can keep an eye on your water heater. You may attempt to adjust the temperature dial and do certain things to fix the problem with your water heater, provided that it is safe to do. Follow us for more useful information on how to save money.
Modern household water heaters are expected to operate for 8 – 12 years. Unfortunately, many water heaters never last this long due to lack of water heater maintenance. This means many people never get the most out of their water heaters. The following tips may help resolve this problem.
i) Flush the Water Heater Regularly
Flushing is the process of removing sediments, impurities and dirty water that may settle at the bottom of the water heater tank. It entails draining water through the drain valve at the bottom of the tank, running more cold water into the tank and repeating the process until clean water comes out. Flushing can be done as a DIY project, but hiring a professional is recommended if you know little about water heaters.
ii) Insulate the Heater Properly
The efficiency and performance of your water heater depends on the type of insulation you have. The insulating material reduces heat loss to the surrounding, so your heated water can stay hotter for longer. In addition to insulating the water tank, be sure to also insulate hot water pipes running from the heater to faucets and shower heads. Proper insulation can save you a lot of money in the long run.
iii) Inspect the Anode Rod Regularly
The anode rod in your heater is responsible for maintaining cleanliness in the water heater. It is normally located in the upper section of the water heater. Ideally, you should check the anode rod annually and replace it if necessary.
iv) Adjust the Temperature Setting Accordingly
Water heaters normally come with a default setting of 140 degrees Fahrenheit, but this is just too hot. In fact, most homeowners would live comfortably with a temperature of 120 degrees Fahrenheit. Lowering the temperature setting will not only lower your energy bill, but also improve the performance of your water heater.
v) Check the Rated Life Expectancy
Knowing when your water heater is expected to expire is crucial as it will enable you to start making early preparations for a replacement.
Water heater maintenance can help you get the most out of your water heater. It will also reduce your monthly heating bill as well as extend the lifespan of your water heater. Follow us for more great articles on heating, air conditioning and home needs.
When it comes to purchasing heating and cooling equipment for your home, you need to realize that size really does matter. Installing equipment with a capacity that matches the home’s size will decrease energy usage while improving comfort for you and your family.
Home builders these days are constructing more energy efficient homes. The installation of double-pane windows, weather-stripping, insulation and caulking reduce heat gain during the summer and heat loss during the winter. This allows homeowners to purchase and install smaller systems than they needed in the past without sacrificing comfort.
Anyone who thinks bigger is better when purchasing a heating and cooling system should think again. Purchasing something that is too big for the space is the most common HVAC sizing mistake consumers make. An oversize HVAC system will produce large temperature swings making it difficult to maintain comfort. It will not run long enough to remove all the moisture from the air, which makes it feel clammy. In addition to being uncomfortable, high humidity can promote mold growth, which is a health hazard.
Residential Load Calculation is the Manual J method of HVAC sizing created and recommended by the Air Conditioning Contractors of America, or ACCA. Residential Duct Design is the Manual D method of HVAC sizing used when the system includes ducts.
Both manuals take into account a variety of factors that affect a home’s requirement for heating and cooling. These factors include the number of occupants, climate, house size, house shape, roof surface color, which way the house is oriented, air infiltration rates, the types of home appliances and lights giving off heat and ceiling, window and floor area.
An experienced estimator will calculate room volumes, estimate air leakage and check the R-value of the insulation. The process should include inspecting the condition of seals and insulation as well as duct distribution in a forced air system. The contractor should provide a written estimate for sizing the system, a contract and a written warranty on labor and equipment.
Purchasing the right size HVAC system is the best way to ensure your home is energy efficient and comfortable year round.

Water heaters are one of the larger and more expensive appliances in a home. They are typically placed in an inconspicuous location within the home, such as a corner in the basement. The location can be the root of an “out of sight, out of mind,” attitude that often results in neglecting the ongoing condition of a water heater.
Homeowners typically get a wake-up call when a shower turns cold due to an irreparable water heater that needs to be replaced. The silver lining will generally be the purchase of a much more energy efficient model that will, in the long run, save money to the homeowner. There are other elements to consider before making a water heater shopping trip.
Tank Or Tankless
Tank or tankless water heaters can operate with gas or electric, and both are available in sizes that are dependent on the water capacity that is needed for a particular home. Conventional tank water heaters should coincide with the number of bedrooms and bathrooms within a home. Tankless models are purchased on the basis of a predetermined flow rate measured in gallons per minute (GPM). The flow rates for fixtures or appliances that are primarily used in a home are combined with the expected water temperatures for each function to determine the necessary size of a tankless unit. Hybrid water heaters operate with electric and are more expensive at the time of purchase, but save money over the course of a year. Modern technology allows a heat pump to draw in surrounding air and use extracted heat to provide water at warmer temperatures.
Energy efficiency should be a primary concern to save on cost and overall energy use. Water heaters with an energy factor (EF) closest to 1 will be the most efficient.
Other Desired Features
Once a water heater is chosen, its dimensions should be taken into consideration for an ideal fit. Larger units might need additional plumbing. Remember to pay close attention to other options such as self cleaning, which will promote the longevity of a water heater. A quick recovery speed indicates how quickly a tank of water will be heated and an auto shutoff valve can prevent a catastrophic fire when using a gas-operated water heater. Take time to thoroughly research available water heaters while contemplating the advantages and disadvantages of each model.
