Sugar Hill Heating Installation Question: What Exactly Are High Efficiency Boilers?

Friday, February 17th, 2012

You have already read plenty about how energy costs are rising. You know plenty well that heating your Sugar Hill home is a substantial expense, and that the cost of running a boiler is constantly on the rise.

But as technology has gotten better, so have boilers become more efficient at providing heat. It stands to reason that a more efficient boiler is one that costs less to run…but what does “efficient” really mean in the context of boilers? What makes a boiler “high efficiency”?

 What Is a High Efficiency Boiler?

All boilers are rated according to a standardized system of rating efficiency, called the Annual Fuel Utilization Efficiency (AFUE). Essentially, this rating tells you how much heat energy is produced by a boiler compared to how much energy it draws. The higher a boiler’s AFUE rating, the more efficient it is.

For a boiler to be called high efficiency, it must carry an AFUE of at least 90%. For basis of comparison, older systems carry an AFUE of about 70%, while mid-efficiency systems run at about 82%.

In addition, a high efficiency system has a second heat exchanger for capturing and condensing flue gases, as well as a closed combustion system.

These three things — an AFUE of 90% or above, condensing flue gases and closed combustion – define a high efficiency boiler.

The initial investment in a high efficiency boiler can be costly, but the savings over time in heating bills make it well worth the expense.

If you would like a high efficiency boiler installed in your home, give Triad Mechanical a call today!

Pros & Cons of Heat Pumps: Some Tips from Statham

Wednesday, November 23rd, 2011

When deciding on any major purchase for your Statham home, a critical step is to weigh the pros and cons. This helps you to decide on the best option and reach the best decision for your needs and preferences.

Installing a new heating system is a perfect example of a situation in which you would need to weigh pros and cons. There are a lot of options, and not all of them are right for all people. Take heat pumps, for example. They are great devices and serve many people extremely well as home heating solutions, but they are not without their drawbacks. Below are some of the pros and cons of heat pumps to help you decide whether a heat pump if the way to go for you.

Pros:

  1. Inclusive – A heat pump not only heats your home in the winter but also cools it in the summer, thanks to a reversing valve that changes the flow of the refrigerant. Having one appliance for both heating and cooling can be very convenient.
  2. Energy efficient – Heat pumps are extraordinarily efficient when it comes to energy use. Because they simply move and distribute heat, rather than producing any on their own, they use minimal electricity.
  3. Simple – Operating on the same basic principles as your refrigerator or an air conditioner, heat pumps are relatively simple. More importantly, they simplify your life by putting your heating and cooling solutions in one package and running on electricity, so you don’t need any other fuels on hand.
  4. Inexpensive to operate – In addition to being energy efficient – which lowers your monthly energy bills – many heat pumps are eligible for federal tax credit. You can save a bundle by using a heat pump.

Cons:

  1. May need supplementing in cold climates – In climates where winter temperatures stay below 30 degrees Fahrenheit for a while at a stretch, a heat pump will have trouble keeping up and need to be supplemented.
  2. Don’t work in power outage – Obviously, because they are powered by electricity, a heat pump won’t work in a power outage, unlike some other heating solutions that do not require electricity.

Although the pros clearly outweigh the cons here, the cons are important as well. Carefully consider all these factors and more while deciding whether a heat pump is the solution for you. And if you have any questions, talk to your Statham heating contractor.

Heating System Preventative Maintenance: Some Pointers from Auburn

Monday, November 14th, 2011

Ben Franklin once said, “An ounce of prevention is worth a pound of cure.” His famous quotation can apply to many things in life, including the heating system in your Auburn home. While heating systems in Ben Franklin’s time consisted of wood burning stove and fireplaces requiring little maintenance, today’s sophisticated furnaces and building controls require a good dose of preventative maintenance in order to avoid mechanical failures and inefficient operation.

For example, a furnace runs better and lasts longer when you maintain a regular schedule of filter cleaning or replacing. A dirty or clogged filter can restrict airflow from the furnace into your home’s ventilation system and cause the furnace to work harder, putting more wear and tear on it and taking months, if not years, off of its useful life. If your furnace uses disposable filters, check them every month and replace them if necessary. If your furnace uses an electronic filter that requires cleaning, check it on a monthly or semi-monthly basis and clean it with soapy water and a hose. Be aware of the change of seasons which could add extra pollutants into the air like pollens, ragweed, and cottonwood. This debris easily finds its way into the filters and creates an unhealthy indoor environment.

You can also perform a simple visual inspection of working components inside your furnace by removing the access cover and checking – with a flashlight – for loose fan belts, frayed electrical wires, or a build-up of dirt and dust. Simple solutions include tightening or replacing belts, repairing wiring, and vacuuming out dirt and dust with a hose attachment. All of these actions will keep your furnace working better and prevent future failures.

You can also do a visual check of your home’s ventilation system, paying close attention to any cracks in duct seams or holes in flex ductwork. Using sealing cement or duct tape can usually fix these problems and allow for better, unrestricted air flow. Again, these actions will help your furnace work more efficiently and avoid premature failures.

Maybe the best advice for preventing heating system breakdowns is to have a regular maintenance schedule with a local qualified heating contractor. Most contractors can set you up with annual furnace and ventilation system inspections. Having a service agreement – as a rule – gives you priority emergency repairs and discounts on parts and services. Besides that, planned maintenance is also preventative maintenance, something that will give you peace of mind in the long run.

Electric Furnace Maintenance Tips from Auburn

Wednesday, November 9th, 2011

Electric heat is clean – but some Auburn homeowners pay for that cleanliness with high utility bills. Depending on the area of the country, electric bills can rival those of gas, oil, or propane. So it is only natural to assume that an efficiently running electric furnace is a must for homeowners who are looking to keep their energy costs down.

Electric furnaces are fairly simple machines. They use heating elements to warm the air, which is then distributed through the ventilation system via a fan or blower. The heating element is made up of a metal wire that is heated by normal electrical current. The element is used to warm or heat something, much like the function of an oven or toaster. Their operation is fairly simple – either they work or they don’t.

When a heating element fails it is usually because it is broken, bend, or misshapen. When that happens, it is time to replace it. You can do some preventive maintenance with a visual inspection of your heating elements. If your inspection does not reveal any problems, you can test the element for continuity. You should know how to use an ohmmeter to test it or ask a professional heating and cooling technician to check the elements for you.

Speaking of visual inspection, you can do a quick check for any frayed or damaged wires, which can be a source for wasted electricity, too. Another way to ensure that your electric furnace is running efficiently is to replace or clean your furnace filters on a regular basis. A clogged filter can make a furnace work harder and lead to premature mechanical failure.

And obviously, if the furnace is not working it is best to check for any blown fuses or tripped circuit breakers in the main electrical panel box. If you find one, make sure you replace it with another of the correct amperage.

Lastly, check to make sure the blower motor is operating correctly. You can have perfectly working elements but if the blower can’t push the warm air through your ventilation system, then all of the steps to ensure the electricity is working are for naught. You can usually hear a noisy motor or smell one that isn’t working improperly. Check it on a regular basis and check the fan belt for any damage or slippage, too.

As you have read, an electric furnace is a very simple machine with simple working parts. Maintaining it is just as simple.

HVAC Maintenance Tips from Atlanta

Monday, October 24th, 2011

Do you hate to work on your own mechanical equipment in your Atlanta home, like furnaces and plumbing fixtures? You aren’t alone. Many people are not cut out to be do-it-yourselfers (DIYers). They prefer to hand off their maintenance and repair chores to qualified professional. That’s not a bad thing. But there are lots of DIYers who prefer to work on their own home repairs – and those are the people who aren’t afraid to take on the most challenging jobs.

If you are looking for good ideas on how to maintain your home’s heating and cooling (HVAC) system beyond the normal filter changeouts, here are some good things to check – things that will help with the overall performance of your HVAC system.

  1. Check the ventilation system. The ventilation carries conditioned air from a main source throughout your home.  It takes a little time and effort to check your ventilation system for things like cracks or leaks around joints, but it is an important maintenance task. You may even find separations between joints or holes caused by nails. A leaky ventilation system could be sending conditioned air into attics, walls, or crawlspaces and making your furnace work extra hard just to keep your living areas warm and comfortable. Take time to visually inspect as much of your ventilation system as possible – usually metal or flex duct – and repair using joint glue, metal filler, or duct tape.
  2. Inspect the insulation. Your heating system works in conjunction with the insulation in your home to provide comfort and warmth while saving you on high utility bills. A home that is poorly insulated or not insulated at all will cause a furnace to work harder and not only send utility bills higher, but increase the possibility of mechanical failure. Replacing or adding insulation in walls and crawlspaces is a relatively easy, yet time-consuming task. You can roll down or tack up fiber insulation or blow in insulation into walls. You can also seal up cracks on your home’s walls, roof, or foundation with a number of different products. Once again, your goal is to make your heating system work less and save you money.
  3. Check the visible components of the furnace. A build-up of dust and dirt can make the moving components of your furnace work even harder, such as the motors, fan belts, contactors, etc. If you live in an area where there is lots of dust and humidity or if your home has several occupants and/or animals, it is particularly important to check your system on a regular basis. This can be done by removing the access panels and taking a vacuum cleaner hose into as many areas as possible. A good, thorough vacuuming should produce immediate results and make your furnace run much more efficiently.

Try these three steps and you may not have to repeat them for another year or so – possibly not ever again while you live in your home.

How Do I Check a Gas Furnace Draft Pressure Switch? A Question from Buford

Wednesday, October 19th, 2011

There are many reasons why a furnace stops working and in many cases, a Buford homeowner can perform some simple diagnostics to pinpoint the problem. Finding the problem is one thing – fixing it is another. When in doubt, don’t try it yourself. Call a qualified professional.

But let’s look at one possible problem and solution you may be able to perform yourself – testing the draft pressure switch. The draft pressure switch on a gas furnace allows an electrical current to pass through to ignite the furnace. The pressure switch monitors the draft conditions and won’t allow the furnace’s gas valve to open unless draft is correct.

If the switch is malfunctioning, so too will (or will not) the furnace.

The best way to locate the switch is by consulting with your owner’s manual or by going online and simply typing in the words “gas furnace draft switch.” It is identifiable by its round size and is bolted to the outside of the furnace. It should be nearby the draft inducer motor because the two are connected by a metal tube. The tube may sometimes be the culprit, too. A tube that is blocked with condensation may cause the switch to go bad.

To check for proper function, first turn off power to the furnace, either by shutting down the “on’ switch at the furnace or shutting off the circuit breaker.

Use a volt ohm meter to check if the switch is opening and closing properly. Start by zeroing out the meter’s probes by touching the tips together. Using the dial (could be analog or digital), set the meter to 24 volts. Ground the black probe by attaching it to any metal part of the furnace. Then place the end of the red probe on the metal tube connecting the draft pressure switch to the draft inducer motor.

If the switch is working properly the meter should read at least 24 volts, or very near that. If the reading is short of 24 volts, the switch is not working correctly. At that point you may decide to replace it or call a professional to do the task (recommended).

Always remember that there are many sources which will help you diagnose and repair a problem, especially those available through the Internet. If you search YouTube.com you will find many videos advising you on how to repair certain components. Use all of the resources available to you and keep the phone number of a qualified and professional heating and cooling contractor nearby.

How to Check if Your HVAC System is the Right Size: A Tip From Watkinsville

Wednesday, October 5th, 2011

Do you ever feel that your Watkinsville home just doesn’t get cool enough during the warm months or warm enough during the cold months? You have tried to adjust your thermostat to the right comfort level but it just never seems right. And on top of that, you notice that your utility bills keep going up and up. Even when you dial up the thermostat in the summer and dial it down in the winter to saving on energy usage, your bills are still about the same.

You could try adding fans and shedding clothes during the warm months or wearing sweaters and crawling under a pile of blankets in the cold months. But do you really enjoy living that way? There must be another solution as to why your heating and cooling (HVAC) system is just not keeping you comfortable – and affordable.

That air conditioning condensing unit sitting in your backyard or the furnace in your basement should be your friends. But in many cases, they are not. That’s because whoever installed those HVAC system components didn’t do their homework on your home. The components were sized incorrectly. If a furnace or air conditioner is sized incorrectly, it usually cannot keep up with the demand for heat or cold and often puts such a burden on the equipment. As a result, regular failures and repair bills are commonplace.

And it may not be the fault of the installing HVAC contractor. Over the years your home may have undergone renovations including additions and new windows, which have increased the square footage or demand for more heating or cooling. Those renovations may not have included upgrades to your home’s HVAC system.

So how do you check for the right size? These checks are done including a load calculation, which adds in the size of your home’s living space, number of door and windows where heat loss or gain could occur, and a check of heat loss or gain through leakage in cracks, roofs, crawlspaces, etc. This will determine what size of furnace or air conditioner is needed to meet the heating or cooling needs of your home and its own individual characteristics.

All of these factors are considered when determining the equipment size. In air conditioning jargon, you will hear about tonnage of cooling capacity. An example may be a 2.5 ton air conditioning unit for a 2,000 square foot home. In furnace jargon, you will learn about Btu ratings, which are British thermal units. Most furnaces are sized in 20-25,000 Btu increments. Each is matched to the cooling or heating needs of your home. Your HVAC contractor will likely recommend using a programmable thermostat, too. That way, you can set the temperature of one or more zones in your home to when each zone is occupied.

Get the Best Value From Your Contractor: A Guide From Buford

Monday, August 29th, 2011

When looking for the best value from a service provider in Buford, it is best to understand what value means to you. The dictionary defines value as “a fair return or equivalent in goods, services, or money for something exchanged.”

In the case of a mechanical contractor, customers are looking for value in the quality of the replacement or newly installed parts or equipment. For example, if your contractor gives you the choice of a product that is warranted for five years versus one that is warranted for ten years – and the price for the longer warranty is within reason, it may be more valuable to choose the product with the longer warranty. It may cost more initially but it is less likely to be serviced as much and will last longer.

Similarly, your contractor may offer a value proposition which includes a “good,” “better,” “best” scenario for the product you are shopping for. You may choose from any of the three based on the amount of time you plan to live in your home or the level of comfort or convenience that you are accustomed to. And, if you choose a “good” product over a “best” product, it may diminish the value of your house when it comes time to sell.

Any good contractor who gives you these choices is one who is giving you the best value.

When it comes to service, there are also value choices, too. For example, how important is it to you to work with a contractor who values your time? Today, time can be just as important as money and is certainly a value consideration. One contractor may only be able to give you a large window of time when his company will be able to serve you, say 8:00 a.m. to 3:00 p.m. Is it worth your time or someone else’s to wait? Another contractor may be able to give you a shorter window – as little as an hour – for you to wait. It may cost a little more but is it worth it to you? The answer is likely to be yes; and this adds a value to the contractor who respects your time.

Another value consideration when choosing a contractor is the “guarantee proposition.” That is, does your contractor have a service or maintenance plan that will keep your equipment in maximum working order based on regularly scheduled maintenance and inspections? Or would you rather hire a contractor to make the original installation or replacement and “hope” there are no breakdowns or expensive repairs during the time you own your home? There is definite value in a contractor who believes that “face time” is a valuable commodity and would be happy to see you on a regular basis to maintain your equipment and keep you up-to-date on any changes that might affect your equipment.

The true value of a contractor lies in the equipment he sells, the service he provides, and the peace-of-mind and time savings you get in return.

Tips from Buford for Controlling Rainwater

Friday, August 5th, 2011

Rain is a necessary evil almost everywhere, including Buford. It waters our lawns, replenishes the ground, stops dust from kicking up and wreaking havoc in our sinuses, and sometimes it’s even enjoyable to experience. Too much rain, however, can lead to all sorts of problems for homeowners. Hassles like flooding, leaks, water damage, and pests can be especially bad for people who live in particularly rainy areas. To make your life a bit easier, keep rainwater under control with some preventive measures.

Around The House

Rainwater clearly belongs outside, and if it gets inside, it can cause problems. Logically then, the first way to keep rainwater under control is to ensure structural integrity and proper drainage. Start on the roof by looking for any loose, damaged, or missing shingles. Replace these and patch any other spots that look troublesome. Repair all leaks promptly, no matter how small they are at first. Even a small leak can become a big problem in a storm, and can also lead to termite infestation. If you find extensive damage to the shingles – say, more than 20% – consider having the house re-roofed.

Next, clean out your gutters. This should be part of your routine spring maintenance list, as leaves and ice will have built up over the last several months. While you are up there, make note of any damage to the gutters and make repairs as necessary. Make sure your downspouts are clear of obstructions, flowing freely, and draining water away from the foundation. These steps are key to proper drainage of rainwater.

In The Yard

After taking care of the house, the next step is to head out into the yard. Take a walk through your yard and look for any areas where the grade is going back toward your house, as well as any depressions where water could pool. Essentially, you want to make sure that any excess rainwater in your yard will be effectively drained away from your house, in order to prevent flooding, water damage, and pest problems. Consider filling, grading, or installing a culvert or other drainage system to correct problems in the yard.

While you are at it, take a look at the driveway, too. Make a note of any cracks or holes that may need to be filled in, as these can also result in improper drainage. If you have a gravel driveway, consider having it graded if it hasn’t been done in a while.

Taking control of rainwater is all about keeping it out and away. These maintenance tips can help you do that. If you want more information about how rainwater can affect your HVAC system, call your local HVAC professional.

How Bad Is the Air in Your Home?

Friday, July 15th, 2011

Every day you hear about another awful contaminant that can get into your home’s air supply. Radon gas. Carbon Monoxide. Nitrogen Dioxide. Smoke. Mold. The list gets longer with each passing year and many homeowners are understandably worried. However, before you run out and by the newest lineup of filters, purifiers, and UV lights, stop and think about just how bad your indoor air actually is.

When Was Your Home Built?

Homes built in the last 10-15 years tend to be well ventilated and may even have air quality systems already in place. It’s those built in the late 1970s and early 1980s that tend to have the worst ventilation (assuming they have not been updated since then).

This kind of poor ventilation can be dangerous, but usually only in that you have less fresh air and more indoor allergens and contaminants. Specifically, you’re most likely to suffer from things like pet dander, dust, pollen, and dirt in the air. On their own, these are not dangerous, but without fresh air to circulate them outside and ensure you get a steady, clean supply of air to breathe, they can make you ill.

How Bad Can It Get?

While it’s rare, some homes suffer from more advanced contaminations. The most common is mold. Mold grows primarily in dark, damp spaces. If your humidity levels get too high in the summer, the ductwork in your house is perfect for mold and it will blow the spores directly into your air, putting everyone at risk.

You should also be wary of exhaust fumes from your appliances that may not get properly removed from the house. Both of these problems can be fixed with regular duct and exhaust cleaning.

Outdoor contaminants can also make it into your indoor air. Things like exhaust and smoke, gas, radon, or other outdoor pollutants should be tested for when you setup a new indoor air quality system. There are filters and purifiers that will remove almost all of these contaminants, but they are not always required, so you should check before making a decision.

Ultimately, the odds are that your home suffers only from some stale, dusty air. But, it is very important to keep everything clean and test it regularly to make sure nothing worse develops. Poor air quality is about more than just comfort – it’s an honest health issue.
