Tacoma HVAC Q/A: What Is an Electronic Ignition?

Wednesday, March 7th, 2012

Gas furnaces in Tacoma are very complex pieces of equipment. Modern ones in particular are designed to use as little gas as possible, and to recapture as much of the heat generated from burning that gas as can be done safely. One of the many safety and energy-efficient advances in furnace technology in the least twenty years is the electronic ignition.

The Purpose of Electronic Ignition

In older furnaces and boilers, a pilot light would stay lit continuously whenever the heating system needed to be available. That meant continuously burning gas throughout the fall, winter and spring months for those times when heat was needed. It was inefficient and unsafe, especially in older devices that didn’t have safety valves.

Today, furnaces are built with electronic ignitions – small devices that only ignite the gas supply when the thermostat is on. there are two types of electronic ignition used in boilers and furnaces today.

  • Intermittent Pilot – An intermittent pilot is unique in that it releases a spark through an electronic component to the gas pilot, lighting the gas burners.
  • Hot Surface Ignition – Hot surface ignition uses an electronic filament (like a lightbulb) to heat up and ignite the burners when the thermostat calls for heat.

Both devices are designed to use a very small amount of electricity and reduce the amount of gas needed for continuous operation of your furnace.

Safety Benefits of an Electronic Ignition

While gas efficiency was a big part of the transition from pilot lights to electronic ignition, safety was an equally big component. Whereas before, the pilot light was continuously lit, meaning gas was continuously flowing into the furnace, today’s furnaces are essentially off when not in use. This means less of a chance that gas will flow unburned or that the pilot will get dirty or burn too soft, releasing carbon monoxide.

If your furnace or boiler still uses a traditional pilot light, consider having it upgraded to electronic ignition, not just to save gas but to keep your home and family safer.  Call Sound Heating for more information.

Redmond HVAC Question: How Tightly Should You Seal Your Home?

Wednesday, January 25th, 2012

More and more products and solutions are available to us these days to help seal our homes off from the outside world. The idea is that by keeping outside air out, our Redmond homes are more energy efficient and healthier, because all pollutants and pathogens are barred from entry.

This is a good idea in theory, but it can have its drawbacks. Most notably, sealing your home up too much can be bad for your family’s health. If your home is sealed too tightly such that there is not enough air flow from within the home to the outside and vice versa, then the indoor air just…stays indoors.

That means that all the sneezes, coughs, dust, dander, smoke and carbon dioxide stay inside with it. All that stuff can make you sick, completely flying in the face of your efforts to stay healthy by sealing your home.

Now, that’s not to say that sealing your home is a bad thing. Using LEED glass in your windows does keep heat in and increase heating efficiency. Air filters do help eliminate pollutants and pathogens from the outside than can make you sick. Good insulation and intact ductwork do help keep your home comfortable and efficient in both the cold and hot months.

So, sealing your home is not a bad idea. The trick is to not go overboard and seal it up so tightly that you are crossing the threshold from having a healthy home to having a giant Petri dish. You want to have a home that is insulated, but not vacuum sealed. You want a home with filtered air, but still plenty of air exchange with the outside world.  Thankfully, mechanical ventilation is a way to both keep your home energy efficient and keep your indoor air from getting stale.

To help you with this endeavor, there are guides available online, such as at the ENERGY STAR website. In addition, it is a good idea to consult with a professional and ask plenty of questions when building a new home or making improvements to your current one. A qualified Redmond HVAC technician will know how to insulate and ventilate your home properly to protect your family’s health.

Tumwater Heating Installation Tip: Pros and Cons of Various Heating Systems

Wednesday, December 28th, 2011

When it comes time to install a new heating system in your Tumwater home, there are a lot of options to consider. Many people get overwhelmed when confronted with all of the furnaces, boilers and heat pumps on the market these days. So, to help you get a handle on what each has to offer and which will offer you the best benefits, here is an overview of the modern heating system market.

Furnaces

Furnaces are the core of a forced air heating system and use gas, oil or electricity to heat air which is then circulated through your home by a blower in your air handler. Furnaces are among the most fuel efficient heating systems on the market today with options available at up to 95% AFUE (meaning it uses up to 95% of the fuel consumed to produce heat). They are also inexpensive to install and while they don’t last quite as long as boilers, they are highly efficient when well cared for.

Boilers

Boilers use gas, oil or electricity to heat water or steam which is then circulated through your home into radiators or baseboard heaters. The heated water or steam releases heat into your home and heats it in turn. While not quite as energy efficient as a high efficiency furnace, boiler heat is perfect for homes with existing radiators and no room for vents and ductwork. It also has less of an impact on indoor air quality since there is no air movement and boilers tend to last a very long time when well maintained.

Heat Pumps

Heat pumps are becoming increasingly popular, especially in milder climates where it rarely gets below 40 degrees F. A heat pump uses the same technology as an air conditioner to extract heat from outside using a compressor, evaporator coils, and condenser coils with refrigerant.

It is most efficient in the spring and fall when temperatures are mild, but it uses much less energy than either a boiler or furnace and it can be used in the summer to cool your home. When properly maintained, a heat pump will last 10-20 years and save quite a bit of money, though it is recommended that you have an emergency heat source for days when the temperature outside gets below 40 degrees F.

How to Get the Best Heat Pump in Tukwila

Friday, October 28th, 2011

Happy Halloween weekend from everyone at Sound Heating & Air Conditioning! We hope you have a fantastically spooky time! But buying a heat pump shouldn’t be scary, even around Halloween. Here are some tips on how to choose the right heat pump for your Tukwila home.

But how do you decide what the best option is, especially when choosing a product that you know little about, like a heat pump? The average homeowner does not spend a lot of time studying his heat pump or reading heat pump magazines for fun, so chances are you are not a heat pump expert. That’s understandable…but it doesn’t help you when you are trying to buy a new one and you want the best.

Fortunately, there some things you can look for to get clues about the quality of a heat pump and how well it suits your needs. Read on to learn more about these indicators in brief.

Efficiency is among the most important factors in choosing a heat pump. Because heat pumps can be used for both heating and cooling, they have two different efficiency ratings, one for each mode.

The heating efficiency for a heat pump is rated on a scale called the heating season performance factor (HSPF). This rating is actually the result of a calculation. To find the HSPF for a heat pump, the unit’s estimated heating output is divided by its energy consumption. Simply put, it’s the ratio of heat put out by the unit to the amount of power it draws. The higher the HSPF, the more efficient the heat pump is. To give a frame of reference, all new heat pumps are required to have an HSPF of at least 7.7. The most efficient units available carry an HSPF of 10.

The rating system used to convey the cooling efficiency of a heat pump is the seasonal energy efficiency ratio (SEER). This is a simple numeric value that rates how efficient the unit is. Many new heat pumps carry a SEER of at least 12, while the most efficient models rate between 14 and 18.

While efficiency is important, it is just one factor. More efficient units are also more expensive, so you will want to consider the upfront cost. The most efficient units will pay for themselves in savings relatively quickly, but the purchase price is still important. Be sure to weigh all the pros and cons when choosing a new heat pump. And if you have any questions, talk to your local contractor.

Who Invented Air Conditioning? Some History From Tumwater

Friday, September 2nd, 2011

For hundreds of years, people have been trying to figure out how to stay cool in the heat of the summer, even in Tumwater. But it wasn’t until 1902 that the first modern air conditioner was put into service in Brooklyn, NY. Since then, many adjustments and improvements have been made to make air conditioning available and convenient for people to use in their homes and cars. But through it all, the basic principles used in that first air conditioner have remained constant.

The Sackett-Wilhelms Lithographing and Publishing Company

The heat and humidity in New York in the summer isn’t something to be taken lightly, but it posed particular problems for the owner of the Sackett-Wilhelms Lithographing and Publishing Company. The conditions inside his facility were such that the paper used was warping and the dimensions fluctuating, causing the printing to constantly come out misaligned.

To try and solve this problem, he hired the Buffalo Forge Company, which itself had just hired Willis Haviland Carrier, a recent recipient of a Master’s Degree in Engineering from Cornell University. Carrier approached this problem by trying to find a way to cool air by passing it over cold coils in the same way air was heated in those days by passing it over hot coils.

As it turned out, this process worked to reduce both the temperature and the humidity in the area and Carrier’s first air conditioner began running at Sackett-Wilhelms in July of 1902.

The Next Steps

As the potential for this new technology became more and more apparent, demand for Carrier’s device grew in all sectors of the economy. Employers were delighted by the way air conditioners increased the productivity of their workers during the hottest months of the year, and in order to keep up with demand, Carrier eventually founded the Carrier Air Conditioning Company which still exists today.

The coolants used in the earliest air conditioners were generally either highly flammable or toxic, and often both. In order to make air conditioning safer and easier to use, a safer coolant needed to be introduced, which was what drove Thomas Midgley, Jr. to develop Freon in 1928. Freon was initially made up of chlorofluorocarbons (CFCs), but as the disastrous environmental impacts of those chemicals became apparent, usage shifted first to hydrogenated chlorofluorocarbons (HCFCs) and then to the hydrofluorocarbons (HFCs) that are predominantly used today.

If you have any questions about modern air conditioning, contact an air conditioning contractor.

Saving Energy with Air Conditioners: A Tip From Tumwater

Monday, August 8th, 2011

Air conditioners can definitely make it easier to get through a particularly hot and sticky summer in Tumwater. But they are also pretty expensive to run, especially if you live in an area with long, hot summers. Fortunately, there are quite a few things you can do to help your air conditioner keep your home cool without running up those astronomical energy bills.

  • Think about Your Thermostat – Most people set their thermostat at one temperature and leave it there. But does it really make sense to pay to keep your home cool all day long when no one’s home? Instead, try turning up the temperature when you leave the house and then again at night before you go to bed. It’s likely you won’t notice the difference and even an adjustment of a couple of degrees can make a big difference.
  • Multiple Climate Zones – When you are home, of course, you want to set your thermostat to a temperature you’ll be comfortable with. But that probably still means you’ll be cooling a lot of empty space. Installing a multi-zone system allows you to set different temperatures for different parts of your home. You can keep the spaces you use regularly cool and comfortable without wasting money paying to cool the unoccupied parts of your home.
  • Ceiling Fans – It might seem silly at first glance to use a ceiling fan at the same time as an air conditioner. But the truth is that using a ceiling fan to compliment your air conditioning system can actually save you a lot of money. Ceiling fans use next to no electricity to operate and they can make the house feel a few degrees cooler. With that added help, you can turn your thermostat up a few degrees without sacrificing indoor comfort and save yourself quite a bit of money – more than enough to cover the cost of running the ceiling fan.
  • Keep Things Sealed – Making sure your house is well sealed and insulated is another important way to keep your energy usage down during the summer. The more cool air that escapes, the harder your system has to work and the more energy it will use.
  • Proper Maintenance – Keeping up with the recommended maintenance for your air conditioning system is the best way to make sure it maintains the highest possible level of energy efficiency. Over time, it will ensure your system stays efficient longer as well – well beyond the initial lifespan estimates.

Do I Need Surge Protection for My HVAC?

Monday, July 25th, 2011

You probably know that to keep your HVAC system in good working order you need to keep up with regular maintenance. This includes things like changing air filters, cleaning out air ducts and clearing debris from both inside and outside the system. Surge protection for your system may not be something you think of immediately, but like those maintenance tasks, it’s an important part of keeping your equipment functioning properly over time.

How Surge Protection Works

Surge protection essentially shuts off your system in the event that power levels in the system rise suddenly and unacceptably. When a sudden increase in electricity occurs, any electronic device is at risk. But, unlike your stereo, your HVAC system costs thousands of dollars – no one wants to lose something so valuable to a surge that could have been prevented. That’s why a surge protector is so vital for your system.

The surge protector monitors the levels of electricity coming into your HVAC system. In the event that a surge occurs for any reason (faulty wiring, a lightning strike, etc.), the surge protector will immediately cut off power to the HVAC unit and shut all of the equipment down.

A Sizeable Investment

Your HVAC system was not an impulse buy. This is a collection of equipment that you probably spent a good deal of money on and that you rely on to keep your family comfortable throughout the year. When you look at it that way, it’s easy to see why it’s worth doing anything you can to protect your investment. Installing a surge protector is a relatively minor expense compared to the money and inconvenience it could save you by preventing serious damage to your HVAC equipment.

Proper Restart

Once a surge protector shuts off your HVAC system, you’ll need to restart it properly. The best thing to do is talk to the contractor who installs your system. They can walk you through the restart process step by step to ensure you know exactly what to do. After going through all that trouble installing a surge protector, the last thing you want is to make a mistake when turning it back on.

If you don’t already have a surge protector in place, call an HVAC professional today and learn what your system needs to be fully protected. It’s a small expense and a quick installation, so there’s no reason to put it off any longer.

The Facts about Indoor Air Quality

Friday, July 8th, 2011

One of the least understood aspects of your home’s comfort system is the indoor air quality. Most people assume that once they have a good furnace and air conditioner installed, there’s nothing left to worry about. However, with the push in the last 20 years to reduce energy loss through poor insulation, most homes are sealed up tighter than ever before. This doesn’t just cause stuffy indoor air – it can actually lead to illness.

How Bad Can Indoor Air Quality Get?

Homes built in the 1980s were recommended to have one third of the ventilation of those built before. Today, the standards have returned to their original levels, but for many years, homes were built with poor ventilation and excessive insulation. The result is a space that holds the air in too well. Everyday contaminants and allergens like dust, pollen, pet dander, mold, or smoke cannot get out of your home and as a result, you can get sick.

In fact, some people even suffer from Sick Building Syndrome (SBS). This is when they feel ill constantly, with respiratory symptoms that have no root cause and are hard to diagnose. Often, it is because they simply breathe too many contaminants and too much stale air.

Fixing Air Quality Is Simple

The first thing needed to fix air quality is a good filtration system. Despite what many people think, simple filtration is not that expensive. There are big, powerful purification systems with advanced ionization units and UV lighting to kill bacteria and viruses, but most families are served well with a simple HEPA filter to remove things like dust, pollen and dander.

It’s a good idea to have your indoor air quality tested, however, just to make sure other contaminants are not present. High humidity can lead to mold growth, and poor ventilation can lead to exhaust or gas fumes in your home. A good carbon monoxide detector is recommended for the latter, but testing should be done to make sure nothing else is floating around.

Finally, make sure your home is properly ventilated. Standard ventilation tends to leak heated or cooled air outside, so many homeowners now opt for energy recovery ventilators. These systems have heat exchangers that transfer warm air between indoor and outdoor air.

However you want to fix your indoor air quality issues, know that there are plenty of things you can do with the help of a good filtration device and regular cleanings of your ductwork and vents.

Save with Maintenance on HVAC

Friday, July 1st, 2011

You can never save too much money by making improvements and taking steps around the house. Of course, it is hard sometimes to see exactly where the money saving opportunities are. That’s because you expect to spend a certain amount on various types of services when you own a home. You know you are always going to have heating and cooling bills, for instance. But are they higher than they need to be?

For many people, the answer to that question is “yes.” And it is not because they use their home heating and cooling systems inappropriately or because they have the wrong equipment. It is simply because they neglect to get their HVAC systems the regular care and maintenance that would keep them running at peak effectiveness and energy efficiency.

When your HVAC system is new, it runs well and can be remarkably energy efficient. However, over time that energy efficiency will gradually deteriorate. This drop off in efficiency is often not obvious at first, but if you compare your energy bills from the year you got your system to bills for the same time of year and same usage five years later, you will probably notice that the bill has gone up quite a bit, and not just because energy prices have gone up.

You can do a lot to prevent this loss of energy efficiency, though, if you simply have a professional HVAC technician come out once a year and give your system a tune up. During this type of maintenance service, the technician will check over your entire system looking for worn out parts and buildup that could be interfering with your system’s performance.

They can clean out any areas of your HVAC equipment that require it and they will be able to make any necessary repairs at that time. Often, a technician performing this type of maintenance will be able to catch minor issues before they are able to develop into bigger problems. And while you still have to pay for the maintenance visit, the cost is much less than what you would pay for an emergency repair.

It also represents a substantial savings over what you would be paying on your energy bills every month without it. Regular HVAC maintenance can preserve the vast majority of your system’s energy efficiency loss over time, and it is never too late to start. Even if it has been several years since you had your system installed, you will still be able to get back the vast majority of your original energy efficiency by starting with regular maintenance now.

Sealing Your Home Can Bring Big Rewards

Monday, June 20th, 2011

You use a lot of energy – and money! – keeping your house at a comfortable temperature. But if there are holes in the “envelope” or “shell” of your home, air from the outside can get into your home and drive up your energy costs.

Sealing the envelope of your home is one of the most cost-effective ways to improve energy efficiency and comfort. Energy Star estimates that appropriate sealing can save up to 20% on heating and cooling costs.

There are three ways to seal the envelope of your home:

  • Sealing air leaks to stop drafts
  • Adding insulation
  • Installing Energy Star windows when replacing windows

Sealing leaks. It may be easy to find some of the leaks in your home, because you can feel and sometimes even see them (for example, around windows and doors). You can seal these leaks with caulk, foam, and weather stripping.

Other leaks may be hidden in attics, basements, and crawl spaces. Common leak spots include:

  • Recessed lights
  • Outdoor faucets
  • Dryer vents
  • Attic hatches
  • Around light switches and cable, phone, or power outlets
  • Chimneys and furnace flues
  • The tops of walls that lead up to attic space

To find and seal these hidden leaks, it may be advisable to hire a contractor who can use special diagnostic tools. The expense is often quickly paid back in increased comfort and reduced utility bills.

Adding insulation. There are several common types of insulation — fiberglass (in both batt and blown forms), cellulose, rigid foam board, and spray foam. Different types are appropriate for different places in your home.

The strength of insulation is measured by “R-value” – its ability to resist heat flow. The higher the R-value, the more insulating power. Different R-values are recommended for different parts of your house, depending upon where you live.

Insulating your attic may offer significant savings, and can be a good DIY project if you are handy. To see if your attic can benefit from more insulation, look across your uncovered attic floor. If your insulation is level with or below the attic floor joints, more would probably be helpful.

Remember, however, that even well-insulated attics need appropriate ventilation to prevent mold growth in the summer and ice buildup in the winter.

Installing Energy Star windows and doors. Replacing windows and doors is a big project and may not generate enough energy savings to justify the cost. However, if you are remodeling or building a new home, be sure to choose Energy Star windows and doors. Energy Star windows and doors will not only help seal and insulate your home – they will also act as a sunscreen to protect your pictures, furniture, and carpets.

After Sealing Your Home: Check Air Quality!

After any sealing or insulating project it’s very important to have a professional perform a Combustion Safety Test on your gas and oil burning appliances to ensure that they are still operating safely.

It’s rare that homeowners seal their homes too tightly – especially if it’s an older house. However, if you are concerned, you can hire a contractor to test your home’s ventilation. If your home is too tightly sealed, he or she may recommend that you install a fresh air ventilation system.
