Where Does Moisture and Water Vapor Come From?

You may be surprised to learn that people are the main culprits when it comes to water vapor and moisture in a home. Despite the sheer volume of environmental water vapor that penetrates the walls of a house, even in a hot and humid climate, it’s far less than the amount of moisture we produce from activities such as breathing, showering and cooking.

A family of four produces about 3 gallons (10 to 14 liters) of water vapor per day, according to the American Society of Heating, Refrigerating and Air-Conditioning Engineers.

And if you think opening a window will do the trick, think again. One thing to keep in mind for hot and humid climates is that cooling by natural ventilation may be counterproductive. It could bring more moisture into the house, which then should be removed through an active dehumidification process. Other strategies, such as shading, could be more effective.

5 Secrets HVAC Companies Won’t Tell You

If your existing HVAC system doesn’t work properly, then it is essential to contact the HVAC operator to repair the system. It is the responsibility of the home owners to select a reliable contractor who holds license and certification.

 

Whether the weather is getting warm or it is freezing, all of us depend on a heating and cooling system. But, what is the correct HVAC system for you? If you already own one, how do make sure it lasts from one season to another? Do not fall into these most common traps.

Size matters when it comes to your HVAC system

Do you buy clothes that are two sizes too big? No! They need to fit. Apply the same logic here. The HVAC system you install needs to be consistent with the size of your property. The bigger units will heat or cool quickly, thereby shutting on and off fairly repeatedly, making room for various issues.

A unit should not cycle on and off too much or you will incur more repairs cost. Electricity consumption also increases and causes higher electricity bills. Bigger units are expensive, not only to buy, but to install as well. To make the right decision on what size unit to install, ask the technician what calculation were used to arrive at the load required for your property.

Carefully consider part replacement

You call over a technician for air conditioning or furnace repair and he points out a part and says “take a look, this needs replaced.” Please think seriously about replacing it. Whenever a technician or an expert says something needs replaced, accept that you may not know everything about your unit. But that does not mean you shouldn’t seek a second opinion. Ask your questions and do your research and understand why the changing of the part is important.

What are the Advantages of a Split Air Conditioner?

Air conditioning has become such as integral part in our lives, even though we do not give much thought to it. Whenever you are out shopping, all the centres will surely be air-conditioned. Whenever the weather gets hot, you will be desperately looking for air-conditioning place to cool yourself.

 

For many homeowners, a split air conditioner is a great option for keeping their home cooled off during the hot summer days. Not only is the split air conditioner an efficient way to keep rooms cooled down, they are also a cost effective air conditioner.

Cost vs Expense

A split air conditioner will cost you more in the initial purchase than a regular window type air conditioner. The unit itself is a two part air conditioner that does not install the same way that a window type conditioner will. You may spend up to $300 for a window air conditioner. However, the split air conditioner can cost $3000 after the installation. In the long run, the cost of running the split air conditioner will actually be lower.

Installation

The split air conditioner is has that particular moniker for the fact that is has two pieces. There is a cold unit and a warm unit. They are separated to make the air conditioner more efficient in the way that it cools down the air and flows through the house. Of course, this means that this big advantage – being more efficient – also carries with it a certain disadvantage.

The installation is much more involved than simply resting it into a window. You have an outdoor condensing unit and an inside unit. They are attached by tubes and ducts that transfer the air. Installation requires cutting holes into the home, finding a stable place for the outdoor unit, and placing the cooling system in a furnace or other area where it can use the home’s duct work.

Whole House Cooling

The reason that the split air conditioner is so advantageous over window type air conditioners is that they cool the entire house. Using the existing duct work in the house, the cool air is transported not in just one room, or …

Benefits of Biomass Boilers

(C) energymyway.co.uk

Given that traditional energy supplying approaches are escalating in price and people have become more aware of the impact they’ve got on the environment, alternative methods are becoming increasingly popular since they’re more eco-friendly and reasonable. A very common alternative is biomass boilers.

a) Organic

The materials used to fuel the biomass boiler are organic compared to fossil fuels which will eventually come to an end. There are many alternatives with regards to the kinds of fuel you may use for a biomass boiler, some of which include wood chip or sawdust as well as municipal solid waste, which would lower the amount found in landfills. Despite the fact that larger amount are needed than previous it is still much more affordable to gain power in this manner.

b) Versatile

This type of heating system can be made use of for almost any objective, whether for steam production, water production or area heating in structures. Biomass is made use of mainly as the fuel however some of the systems could utilize biomass with a fossil fuel as a back-up for satisfying top needs. These could be applied in almost any scale, whether in district, industrial, domestic or slightly commercial heating.

c) Cheaper

Biomass systems can be a less costly system for heating as well as electrical energy. Even though initial expenses could be high, long-term savings can be fairly great. There are many forms of biomass boiler designs on the market, presented in different price ranges. Even though the ones ideal for complex industrial purposes come in about 100,000 USD, the easiest ones which are by hand operable in kind come in about 1, 000 USD. Given that easily obtainable waste material can be used as fuel, they’re perfect options for people working and residing in remote and rural areas who cannot get access to woodchip suppliers.

d) Lower CO2 emissions

You are going to lower your carbon footprint. Biomass fuels do discharge carbon in to the environment however only a portion compared to fossil fuels. It is computed that the annual carbon dioxide emissions for heating a medium-sized house based on gas and oil is approximately 30 times higher than for biomass wood chips. That is a huge difference.

e) Reduced use of landfills

A portion of landfills consists of woody biomass from construction, lumber mill activities, disposal of wooden pallets, etc. Waste products from food processing, paper industries and home garbage also contain organic matter which can be converted to energy. Using these materials to create energy as biomass means less landfill space is needed hence protecting our environment further.

Biomass is used mostly as the fuel however some of the systems can use biomass with a fossil fuel as a back-up for fulfilling peak demands. Biomass systems really are a much cheaper system for heating and even electrical power. In comparison with those utilizing fossil fuels, biomass boilers lead to lower carbon dioxide emissions.

5 Signs for an Air-conditioner Repair

Having a fully-functioning air conditioner is practically a right for property owners. A few cities are intolerable without this vital feature. Losing the use of an air conditioner just for a single day is difficult, particularly in the intense summer. At the end of the day, walking from the car towards the door is made bearable with the anticipation of a cold home as soon as the threshold is crossed.

Whilst they might appear to be tiny problems, overlooking the warning signs can lead to discomfort and overspending. Professional air cooling services are not free. As a result, before calling anyone to your house, you need to be able to evaluate if you need one in the first place.

Odd odors
Air conditioners shouldn’t smell odd. When there is an odd smell coming from an air conditioner, it might mean not so good, both financially and medically. Odd odors could mean an overflow drain has issues with bacteria or mildew. In old properties, it could be essential to have the duct work cleaned to remove odors related to smoking or age.

Strange noises
The sound of an air conditioner is becoming part of the normal background noise in some homes. Few individuals actually observe it anymore. However, when that sounds changes in any manner, it abruptly becomes very noticeable. It is additionally an indication that someone needs to get in touch with their air conditioning repair services. A squealing sound can point out an issue with a belt, like one might experience in a car. Rattling noises could mean an element is loose and then it really is crucial that you call a professional.

Warm or stale air
Have you found that your air conditioning unit just isn’t as effective as it used to be? Whenever you place your hands to the vents are they much less cold as always or not cold in any way? This can be a problem like compressor failure, or perhaps your systems Freon levels are just way too low. When you observe an issue like this, you need to call a professional repairman to come out and take a look

Vacillating temperatures
In case you are having thermostat issues and your air conditioning system is performing inconsistently, this may mean that you have a malfunctioning thermostat. A good way to tell if it is an issue is if a section of your property is cold while another part is not at all.

Leaking Fluids
Air conditioning units are subject to condensation, as moist air passes across the cold evaporation coil. Yet, should your unit is visibly leaking fluid; you may have a mechanical problem that will require the attention of an air conditioning contractor. Water leakage inside or outside your home might signify the coil drainage system-where the condensation is routed-is stopped up. When you notice oil leakage, you may have a rust problem which is reducing performance.

Attic Exhaust Fans

Attic exhaust fans are absolutely crucial to keeping a healthy home. The main purpose of attic exhaust fans is to provide ventilation to help control the temperature in your attic.

 

Attic Exhaust Fan

Attics can collect heat, increasing your cooling costs in the summer, and moisture, which can result in mold, but these issues are remedied by installing an attic exhaust fan.

How Attic Exhaust Fans Work

Installed in your roof, an attic fan draws heat from your home and attic and pushes it outside, while pulling cooler air into the space. Think of the exhaust fan in your bathroom: it works in much the same way. However, attic fans aren’t all created equal. there are a variety of choices depending on your home’s needs.

Look for fans made of metal, which are the most durable, and that incorporate a screen to keep insects and other pests out. Fans may be installed on your roof top or at a gable-end.

Traditional Attic Fan

For many homes, a traditional fan suffices to cool the attic. You’ve seen these space-aged, dome-shaped fans that are driven by a belt. A drawback is that they leave an opening in the roof, which allows cold air to infiltrate in the winter. They can also be loud and require frequent maintenance as the belt can wear out.

Electrical Attic Fans

Electric fans can move large volumes of air. Many include thermostats that help save energy. They are more difficult to install than traditional attic fans because they require wiring.

Solar Attic Fan

Save on operating costs by using a solar powered attic fan. However, efficiency can diminish if there is not enough light to power it.

Wind-Powered Fan

If you live in a windy area and are seeking an environmentally friendly attic exhaust fan, consider the wind-powered fan. Wind blows the turbine vent, which in turn generates an air current that cools your attic.

Difference Between Best HVAC Brands

Building a new home or upgrading an existing one? Air conditioning and home heating is an important part of that process. So what do you consider when choosing the best air conditioning brand for your home.

two men installing an HVAC unit

If you’re in the market for a new furnace, air conditioner or heat pump system, then chances are that you need to hire someone to install it properly.

So you went online to start figuring out which brand, which model, which size, which contractor, how much, what financing options, etc. — a lot of things to consider!

Couple that with the fact that this expense is most likely unplanned, perhaps even an emergency situation, and it becomes quite a big decision that needs to be made quickly. Here’s how to do it:

Why do you want to replace your HVAC system?

If you’re shopping for a new HVAC system because you recently had service, and the service tech told you that you had to, or that it’s dangerous, then let’s take a step back for a second.

It’s very rare that a system must be replaced. Now, sometimes repairs can cost as much as a new system, but that doesn’t mean you must go that route. There are almost always options for repair.

So, if your answer is, “because I have to,” then get a second opinion.

RELATED: 3 Tips to Avoid Poor HVAC Service

Now, maybe that system is getting old and you just don’t want to deal with annual repairs, or you want higher efficiency to reduce those utility bills, or your system has never heated or cooled your home just right. OK, those are some good reasons to replace your HVAC unit.

Anyway, it’s time to pick a contractor. Wait a minute, what about brand?

Who is the best HVAC manufacturer?

I have an Apple iPhone, a Honda Civic, and I’m reading this on a Sony laptop while drinking my Starbucks coffee! Brands are burned into our psyche as Americans.

For most purchases we make, you pick the brand first, then go to a dealer or retailer. Here is how the story goes: I see an ad for a Honda Civic, see people driving them around and now I want one.

How to Clean and Straighten AC Condenser Coils

The condenser coils are a vital part of your air conditioner unit. Without it, your aeration and cooling system won’t work appropriately. It is therefore vital to keep it in working condition.

 

The AC condenser coils need regular maintenance and cleaning along with the indoor AC evaporator coils because the condenser unit is other half a split central air conditioner system. The purpose of the condenser coil is to release the heat absorbed by the refrigerant at the evaporator coils inside the home so it’s ready for the next cooling cycle. If the condenser coils are clogged with dirt or the fins are bent it will block air flow through the coils and interfere with the heat exchange. This causes the system to work harder and drives up your electric bill.

 

Bent AC Condenser Coil Fins

The air conditioner system was installed by the home builder and are now about 12 years old. The Heil “entry model” or economy condenser units have coils that are protected by a wire grille which in reality isn’t much protection. I noticed the condenser coil fins had become bent and damaged sometime in the past 2 years. Were the fins bent by the hail storm or more likely by the pressure washer guy?

The bent condenser coil fins are very noticeable in the 2012 photo. The damaged fins are straightened by fin combing in the 2014 image:

How to Clean and Straighten AC Condenser Coils

I called my HVAC service company for the twice a year seasonal maintenance and asked for condenser coil cleaning and fin combing to straighten the bent fins which cost an extra $125 per unit.

These are 3 ton (or 36,000 BTU/hr) condenser units. The coils are painted black by the factory which has mostly worn off. The coils show numerous silver looking areas with bent fins or impact damage. The individual strikes could be something thrown by the lawn mower or a hail strike. That bent fins near ground level are probably from careless use of the weedeater. I believe the pressure washer guy caused the large area of bent fins at the left corner when he cleaned the house (BTW – never pressure wash AC coils!):

5 ADVANTAGES OF DUCTLESS COOLING AND HEATING SYSTEMS

There are many different ways to keep your home comfortable. A ductless cooling and heating system provides efficiency and energy savings ideal for each and every home.

 

Modern living room with wall-mounted ductless unit

Most people have heard of ductless cooling and heating systems, and they have probably seen the small, indoor devices installed high on walls in homes, restaurants or office buildings. But what do you really know about these systems?

1. They Offer Highly Flexible Solutions

Whereas traditional heat pumps and central air conditioning systems force cooled and heated air through ducts, ductless systems deliver air directly into different zones. They are comprised of a small outdoor unit and one or more indoor units that require nothing more than mounting capabilities and access to electricity.

Sometimes referred to as split systems, multi-split systems, or split-ductless systems, ductless cooling and heating offers home and business owners a cost-effective way to replace inefficient window units, space heaters and electric baseboard heaters. They can be installed in home additions, new construction, condominiums and apartments, or to improve temperature control in specific rooms. Ductless systems can even be fit for buildings that currently use ducted forced-air systems.

2. They Save You Money

One of the biggest reasons why homeowners switch to ductless cooling and heating is overall cost savings. In recent years, utility costs across the country have skyrocketed. When a home’s temperature depends upon an inefficient system, monthly bills can quickly climb out of control. Ductless systems operate on less power – they are smaller than traditional forced-air systems, and because the temperature-controlled air is delivered directly into a room, there is no loss in efficiency. Multi-split systems also allow homeowners to …

Biomass

Biomass has been around for the last 10 years, but only now is it becoming popular. What is it so? What did people discovered that gained their interest in such?

 

Wood burning stove image

Wood-fuelled heating systems, also called biomass systems, burn wood pellets, chips or logs to provide warmth in a single room or to power central heating and hot water boilers.

A stove burns logs or pellets to heat a single room – and may be fitted with a back boiler to provide water heating as well. A boiler burns logs, pellets or chips, and is connected to a central heating and hot water system. A wood-fuelled biomass boiler could save you up to £990 a year compared to electric heating.

The benefits of biomass heating

  1. Affordable heating fuel
    Although the price of wood fuel varies considerably, it is often cheaper than other heating options.
  2. Financial support
    Wood fuel boiler systems could benefit from the Renewable Heat Incentive.
  3. A low-carbon option
    The carbon dioxide emitted when wood is burned is the same amount that was absorbed over the months and years that the plant was growing. The process is sustainable as long as new plants continue to grow in place of those used for fuel. There are some carbon emissions caused by the cultivation, manufacture and transportation of the fuel, but as long as the fuel is sourced locally, these are much lower than the emissions from fossil fuels.

If you live in Scotland, view case studies and examples where homeowners have installed a wood-fuelled heating system.

Costs, savings and financial support

Costs

For boilers, an automatically fed pellet boiler for an average home costs between £9,000 and £21,000, including installation, flue, fuel store and VAT at 5 per cent. Manually fed log boiler systems can be slightly cheaper.

Pellet costs depend mainly on the size and method of delivery. If you have room for a large fuel store that will accept several tonnes of pellets at a time, delivered in bulk by tanker, you can keep the cost down to around £220 per tonne in most parts of the UK.

Logs can be cheaper than pellets, but costs depend on the wood suppliers in your local area, as they cost a lot to transport.If you have room to store more than a year’s worth of logs you can save money by buying unseasoned logs and letting them season for a year. Search for wood fuel suppliers in your area on the Biomass Suppliers List.

Savings

Savings in carbon dioxide emissions are very significant – up to 15.7 tonnes a year – when a wood-fuelled boiler replaces a solid (coal) fired system. Financial savings are more variable – if you replace an ….
