Insulation Tip: Benefits of Insulation Replacement

Monday, January 28th, 2013

The benefits of insulation replacement really depends on the condition of the insulation in your Melbourne, FL area home, the climate, your home’s design, and even your budget. Call Next Generation if you have further questions or would like to set up a consultation. Meanwhile, here are some of the basic benefits of insulation replacement.

Insulation is measured by different values called the “R-value.” The greater R-value, the more heat flow resistance you get to prevent energy loss. This also helps protect against problems related to excess moisture. When we assess your home, we will be able to consult you on what type of insulation is best for you. Sometimes you may need to use higher R-value insulation on exterior walls and in attics, but these spaces are not always easy to get to. You may need to install blow-in insulation or another type that suits your particular home and needs.

In addition to preventing energy loss, adding insulation can also help detect areas where there are other issues that need to be taken care of. Dirty insulation can indicate a ventilation issue, which will affect where the insulation is installed.

Attic insulation is one of the places in your home that will probably need more insulation and ventilation. This helps protect against heat loss in the winter and keeps your home cooler in the summer. You easily can tell whether or not your attic has enough insulation by the way it feels in there. A drafty attic in the winter and hot one in the summer could mean that your attic needs more insulation or sealing.

Air Conditioning Guide: Causes Of AC Short Cycling

Monday, September 10th, 2012

Especially if you live in a very warm climate, you know how important it is to maintain your Rockledge air conditioning system to keep it working properly. So if your AC turns on and off repeatedly in short period of time, you should suspect that it is not functioning effectively.

This is also called as AC short-cycling. It is a problem because it makes your indoor environment less comfortable, and also because it makes the components of the AC wear out faster. If you notice the symptoms of AC short-cycling in your home, you need to call a Rockledge air conditioning professional to test your AC unit immediately.

Here are some of the causes of an AC short-cycling that need quick fixes.

  • AC Refrigerant Leaks: A refrigerant leak within the AC unit might be a cause for short-cycling. You need to contact an HVAC professional in order to find and repair the leak properly and make sure that the problem does not recur.
  • Ice on the AC Coils: This can happen when the cooling or evaporator coil has been coated with the ice or frost. To correct this, the unit should be completely turned off in order to let the ice melt. Testing and replacing the dirty filters is also recommended to keep the problem from coming back.
  •  Oversized AC System: If your AC system is too big for your home, it may result in a short-cycling problem as well. Bigger does not mean better performance in all cases. If your AC is too big, it will create uneven cooling, irregular dehumidification and also short-cycling. In order to avoid this type of problem, you have to call a professional to calculate the total cooling load in your home and ensure that you are getting the right system for your needs from the beginning.
  • Problems in the AC Control Board: This will create inconsistent starts and stops in cooling cycles, especially if the control board or switch of your AC system is damaged. If that’s the case, you have to contact an AC technician to replace the broken control board or switch.

Your AC may be functioning, even if it is also short-cycling. But it is not effective and efficient. So call Next Generation Air & Heat Inc. immediately to take steps to correct this type of problem.

Insulation Question: What is R-Value?

Tuesday, September 4th, 2012

The R-Value of insulation is a measure of that material’s resistance to heat flow. In other words, this tells you how effective that insulation is at keeping heat in or out of your Melbourne home. Insulation is more effective if the R-Value is higher. Factors that influence this value include the type of the insulation in question, its thickness, the material it’s made from and its density.

If the installation has more than one layer, R-Value is calculated by adding the values of I the individual layers together. The location where the insulation is installed also plays a major role in determining the effectiveness of heat flow resistance.

For instance, full-rated R-Value will not be provided by compressed insulation. There will be a difference in the R-Value of the insulation when it’s installed in a ceiling or wall, as heat tends to flow through the joists and studs. To ensure optimum value, it is important to install insulation in a proper manner and with the help of qualified professionals.

Factors that Influence Quality of Insulation

The amount of insulation required for your home depends on the type of cooling and heating system you have, the climate you live in and the area in your home you wish to insulate. High quality insulation with a good R-Value is often applied by spraying. This ensures that every single cavity in the building will be completely filled to prevent any convection heat loss.

Use the Right Insulation Material

In order to prevent any heat loss through radiation and air infiltration, the insulated area should be densely packed. Cellulose is one of the most popular materials used for insulation. This material offers optimum insulation, blocks sound transmission and prevents quick spreading of flames in case of fire.

Areas that Need Insulation

One of the most common questions people ask is whether all areas of their homes require insulation of the same R-Value. Wood framed walls, crawl spaces with walls, and basements require lower R-Values than rooms with cathedral ceilings and attics.

What is a Whole House Fan?

Wednesday, July 13th, 2011

Cooling your home is a big deal. Especially if the temperature in your home is generally very high in the summer, the cost of air conditioning is tremendous. A central air conditioner can cost between $2,000 and $4,000 to run for an average 2,800 square foot home over the course of six months. That’s a lot of electricity just to stay cool.

That’s why a whole house fan is a great option for those that want to forego the use of direct air conditioning for at least part of the year.

What It Does

A whole house fan is different from a standard air conditioner because it doesn’t use a heat exchanger to remove heat from air before it enters your home. That heat exchanger is the culprit for a large percentage of an air conditioner’s energy consumption. A whole house fan can be used when the temperature outside is lower than inside, a common occurrence on moderate days in the summer.

The whole house fan draws air and then cycles it through your air vents without cooling it. The act of moving air through your home, however, is often enough to cool the space to a comfortable level. The size of your whole house fan depends on quite a few things. First, how big is your home? Large homes that require even cooling need a larger fan to draw in air. However, small homes can often get away with models that use as little as 120 Watts of electricity. That’s less than your computer uses.

Choosing a Fan for Your Home

Keep in mind that a whole house fan only works when the temperature outside is lower than inside. If the air outside is excessively humid or if it is very warm in the hottest months of summer, you will still need an air conditioning unit. But, even if you run your air conditioner for two months out of the year, you’ll save a tremendous amount of money in the other four months by operating a whole house fan.

Whole house fans should be used in conjunction with an effective air purification system to ensure all outdoor contaminants are effectively removed before they are cycled through your house. They also require the same level of maintenance and cleaning as a normal AC system. However, with the right care, they work wonders to cut down on your energy bill.

The Energy Efficiency Rating of Central Air Conditioners: What Is it and Why Is it Important?

Friday, July 1st, 2011

When you are shopping for a central air conditioning system, you will have to evaluate your options based on a number of different factors. For instance, you will need to decide which type of system is the best match for your home and for your particular cooling needs. It is also important to make sure that the central air conditioner you choose is the right size for the cooling load it will have to take on.

However, it is also very important to evaluate your central air conditioning options based on how energy efficient they are. This will have a great deal to do with how much you pay in terms of cooling costs each month, which makes it easy to see why you should take it into account before you make a purchase.

The energy efficiency of a central air conditioner is generally expressed as a seasonal energy efficiency rating, or SEER. The SEER numbers you will typically find on the latest air conditioning systems range from eight to 19.5 with the higher numbers signifying a more energy efficient model.

So it is pretty easy to figure out that a central air conditioner with a higher SEER will save you some money monthly because it will use less energy to get the same job done. But central air conditioners with high SEERs also typically have high price tags. So to determine how high of a SEER you need, you will need to know more exactly how much more money you will save as you move up in the rankings.

You can do this by comparing the SEER of the system you currently use with the new system you are considering and compare how much your current energy usage would cost you with each model. Basically, you want to pick a central air conditioner that will save you enough to offset the purchase price of the unit.

Often, this means that you will be best off with a SEER 14 or SEER 16 because these units save you a considerable amount over older models without carrying too high a purchase price. However, the amount you save will be directly related to how much you use your central air conditioning system, so if you live someplace that is extremely hot for a large chunk of the year, it may be worth it for you to buy a very high efficiency air conditioning system.
