No Heat From Your Boiler in Bremerton: Causes and Solutions

May 14th, 2012

Hydronic Boiler Systems in Bremerton are very popular because of their reliability and efficiency. Just like any other appliance though, hydronic heating maintenance is needed periodically, especially as units age, and they can happen for many reasons. The first step is to make sure you’re actually dealing with a breakdown and not something much more simple. If you’ve lost heat from your boiler, check to make sure there’s fuel in your oil or gas tank before making a service call. Also keep in mind that part of the heating system is electrical. A recent power outage or short circuit in the house could have tripped the circuit breaker for the boiler.

Next, check the emergency shut off switch. It looks like a typical wall light switch but with a red cover and bold lettering indicating the off and on positions. It’s usually placed in a convenient spot in the basement. In many Bremerton homes it’s located at the top of the basement stairs. Sometimes the switch is turned off accidentally, but if a repairman or someone else in you house turned it off for a reason, you need to find out why.

If the emergency switch is on and all the circuit breakers are on and there’s plenty of fuel, the next step in diagnosing the problem is checking the boiler. First, understand that most heating appliances automatically shut down when a critical component stops functioning properly. Don’t put yourself or your family at risk. Don’t attempt to restart or repair the boiler yourself. But you can help the HVAC technician help you by checking a few simple things before making the call.

A puddle on the floor usually means a pipe or valve is leaking. A drop in the water level inside the boiler could have triggered the shut down. But leaks in joints can also occur when something else shuts the boiler down and the metal plumbing shrinks. Is the puddle getting larger or is it stagnant?

If there’s no leak, carefully touch the copper pipes running in and out of the top. If some are hot and others cold, the boiler is probably working but some of the zone controls or thermostats may be broken.

If all the pipes are cold, carefully touch the metal panels covering the boiler. They usually warm up a bit when the boiler is operating normally. Listen for the faint hissing sound of the pilot light. If the  boiler is cold and completely silent, the pilot light may have gone out, triggering a shut down. Don’t attempt to relight the pilot unless you’ve done so before. The HVAC technician can show you how to do it. Keep in mind that many new boilers in the Bremerton area have pilotless electronic ignitions.

If the pilot is lit but the pipes and boiler are cold, and boiler uses fuel oil, the burner motor may have stopped working. The burner motor is a separate, smaller unit attached to the boiler. Most burners have a red reset button that pops up when there’s a burner malfunction. Try to locate the button and decide if it’s popped up, but don’t reset it. Call an HVAC technician first. Restarting a malfunctioning unit may cause further damage. Oil burner motors can stop working for many reasons, including soot blocking the air supply, blocked fuel line, dirty electrodes inside the motor, or seized up bearings. Only a licensed HVAC technician can correctly diagnose and fix such problems.

Common Mold Myths in Redmond

May 7th, 2012

You hear a lot of bad things about mold and while a lot of them are true, many are not. To help you avoid unnecessary scares and excessive worry about air filtration in Redmond, here are some of the most common myths we hear about mold:

  • Black Mold!! – Black mold is not the only mold you should worry about. While black mold does produce mycotoxins and can be quite dangerous if it develops in your living space, all molds can be potentially dangerous due to the off gassing of MVOCs and other chemicals. If you see mold – whether green, black, grey, or red – call someone immediately to test and check your home for toxicity.
  • Scrubbing with Bleach Gets Rid of Mold – Mold can be removed with bleach, but only on the surfaces you can reach. Real mold removal uses more advanced techniques to clear away spores, block sources of moisture and reduce the presence of the toxins produced by mold. It’s impossible to ever truly, 100% remove mold from any environment, but with the right abatement techniques, you can reduce its impact.
  • Mildew Isn’t a Big Deal – Mildew may have a different name but it’s the same problem. Mildew is a certain kind of mold and that stale, musty smell you experience when it develops is the development of microbial volatile organic compounds – chemicals like benzene and aldehyde. To ensure mildew doesn’t have a negative impact on the overall indoor air quality, be sure to reduce and remove moisture from your home whenever it develops – in basements and attics as well as bathrooms and kitchens.
  • Mold Needs Organic Material to Grow – Mold can grow on anything with enough moisture. While carpets, upholstery, paper and other organic based materials are more likely to develop mold, it can grow on glass, porcelain and metal if enough of the spores are present. The key to mold abatement is not material changes or closing it out; it is to remove the moisture and seal up holes.

Mold is a major health problem for millions – by better understanding it, you can minimize the risk and keep your family safe. If you suspect mold in your home, don’t wait to have it checked. Call Sound Heating today for full testing, inspection and, if necessary, removal.

Boiler Basics for Tacoma Residents: Know the Components of Your Hot Water Heating System

April 30th, 2012

Hydronic boiler systems in Tacoma, or otherwise known as water heating systems, are becoming very popular. They make use of water’s excellent efficiency for transferring heat. Hot water circulates through the house in a  network of pipes that connect to radiators or baseboard convectors that transfer the heat to the air. Return pipes cycle the water back to the boiler to be heated again.

The heart of the system is the hot water boiler.  As you might expect, boilers get their name because they are boiling water to produce heat. That doesn’t mean there’s a cauldron of water bubbling away inside the boiler’s walls. Water inside the boiler is contained entirely within coils of pipes. Burners beneath the pipes heat the water as it circulates through the pipes. The burners can be gas or oil fired, or electric.

When a pot of water boils on a stove, it sends a lot of heat and steam into the air. Put a lid on the pot and the pressure from the boiling water lifts the lid to allow the steam to escape. Now imagine water being heated inside the coils above the burner.  As the pressure builds it has nowhere to go so it drives the water out of the coils and into the network of pipes connecting to the radiators. As it circulates, the hot water pushes the cooler water through the pipes and back down to the boiler. The movement of the water through the system may be assisted by a motor-driven circulating pump connected to the return pipe where it enters the boiler. The pump creates negative pressure that helps cycle the water away from the boiler, through the pipes and radiators, and back to the boiler.

The basic operation of hydronic systems may sound simple, but safely and efficiently controlling it requires a series of sophisticated components. As the water is piped away from the burners and out of the boiler it flows through a valve connected to an expansion tank, which allows the water to expand as it heats. The expansion tank is a large, cylindrical object that hangs off the pipe exiting the boiler.

The large pipe heading away from the expansion tank is divided into a series of smaller pipes, each of which is connected to a zone valve, a small metal box with electrical wires attached to it. The zone valves are wired to the thermostats in the house. When the thermometer in the thermostat drops below the set temperature, it sends a signal to open the zone valve. The hot water from the boiler flows through the valve and into the series of pipes and radiators that service that zone. There may be one, two, or several zone valves depending on the number of zones in the house.

The boiler is also connected to the house water supply so it can be refilled if it loses water. The water supply is usually a small diameter copper pipe exiting the boiler and connected to a shut off valve. The shut off valve also has a pipe leading away from the boiler and connecting to the house’s cold water supply. There is also a pressure relief valve attached to another small diameter copper pipe running out of the boiler. The valve relieves excessive water pressure that builds up inside the boiler.

Oil heat boilers have an electric burner motor that pumps fuel oil out of the tank and into the boiler. The burner motor is attached to the boiler and should have a red reset button that pops up when the boiler shuts down from a malfunction. Gas powered boilers have a smaller gas valve that regulates the flow of gas into the boiler.

Exhaust gases from the burned fuel are vented through a large diameter stack rising up from the center of the boiler and into the chimney. The exhaust stack may be sealed or it may run into an even larger diameter vent with a cone-shaped skirt.

The aquastat is the electrical switching device that ignites the burners when a zone control sends a signal to the boiler calling for heat. The aquastat may be housed in a small metal box attached to the boiler, or it may be inside the boiler. In either case, it will have thick electric cables leading into it. The last critical component on the boiler is the pressure/temperature gauge. If a problem arises with the heating system, it allows the homeowner or the HVAC technician to determine if the boiler is overheating, losing pressure, or not functioning.

Des Moines Indoor Air Quality Tips: Microbial Volatile Organic Compounds

April 23rd, 2012

Homes if Des Moines can develop microbial volatile organic compounds, which are chemical agents produced by organic materials like mold that can have a potentially dangerous effect on your nervous system. In fact, some MVOCs have an equal or even worse effect on the human body as petroleum based VOCs which have long been labeled as dangerous to inhale by the EPA.

The problem of course is that there are too many talking heads out there telling you that MVOCs will kill you or that they can be ignored. The truth is in between, and for your family to remain safe and healthy you need to keep a close eye on the effects of potential black mold patches in your home.

Handling MVOCs

The first step to reducing MVOCs in your home is mold abatement. Proper removal will reduce the volume of mold that can off gas these chemicals. Additionally, you should reduce your use of such chemicals as aerosol sprays, paints and paint thinners, hobby supplies, air fresheners and other chemicals compounds that produce manmade or petroleum based chemicals that feed mold.  Make sure that your home has proper ventilation and air filtration.

Finally, make sure you have your home inspected as soon as you suspect the presence of mold. Regardless of the mold’s color and the smell you notice, it should be checked by a professional in the mold detection and abatement field. It might be nothing, but if it is something, you want someone you can trust to take care of it immediately.  Ask a professional what type of air purification appliances you should utilize.

Toxicity in Many Molds

The most commonly cited “toxic” mold is black mold or stachybotrys. This mold produces a mycotoxin that can quite literally poison anyone who breathes or ingests it. However, other forms of mold which might appear as red, white, green or grey produce MVOCs that are equally dangerous. Many people with mold have these dangerous chemicals in their home and don’t even realize it.

Typically, MVOCs can be smelled as a musty, organic gas that develops from the mold as it matures. Mold produces a variety of chemicals including benzene, aldehyde, tulolene, more. These chemicals create that musty scent and are all quite dangerous to the human body. Just because a chemical is organic doesn’t mean it isn’t dangerous to your health. Imagine if man made formaldehyde or benzene were in the air near your children – what would you do?

AC Problems You Need A Professional to Fix in Puget Sound

April 16th, 2012

In a hot climate, it’s great to be cool.  Air conditioning in Puget Sound makes life possible for some people.  It lets us sleep and helps us be our best through the hottest days.

Air conditioning is a cool blanket that wraps around us like a mother’s arm around a little baby.  It’s such a part of our lives that it’s easy to forget that, like a baby, our own air conditioners must be well fed and maintained.

Some quick fixes are easy for a home owner, but other air conditioning repairs are complicated, and require a professionally certified HVAC company like Sound Heating to accomplish.

Doing the Basics

For window mounts or the big units on the side of the house, regular cleanings and a filter change should be a part of every season.  Even for the most bumbling of hands, it’s not hard to remove the cover and replace the panel of webbing that catches lint and other particles out of your conditioned air.

Some warm water and a good shot of compressed air gently on the exposed fins will help to increase the longevity of the unit.  Be careful not to put pressure on the fragile fins and coils or use hot water that could cause corrosion.

Make sure the drain is clear, always cover the unit or store it away when more naturally cool temperatures take over and you’ve got conditioned air and relative peace of mind in the years ahead.

Big Problems

Without the regular service, however, an air conditioner begins to work much harder to produce the same amount (or less) of cool joy and parts begin to break down.  With total neglect, the unit itself may need replacement much sooner than was promised when you paid for it. These are repairs that could be avoided and require a professional to make.

The key ingredient to cooling is a chemical called a refrigerant (most often Freon) that is capable of transforming rapidly from gas to liquid and back again at low temperatures. This runs through two intricate tubes, a compressor, and a critical expansion valve that controls the process.  It is a delicate and complicated process that calls for expertise and the right tools, especially since the refrigerant is considered hazardous and requires special handling.

When the air gets stuffy, it could be that the fan is the problem.  Belts could be worn, loose or broken.  The motor may be low on oil and is stained to the breaking point.

If mysterious signs of water or mold are showing up on the inside of the house near the unit, there could be a problem with the condensate that is released with the heat when air is cooled.  This could be a simple or complicated fix, but should be checked out professionally to ensure all is well.

With love and care, an air conditioner should provide us with a decade or two of wonderful sleep and cool times.  Schedule regular service with Sound Heating to increase the comfort.

Eatonville Heating Q and A: What Is a Gravity Furnace?

April 9th, 2012

A long time ago, gravity furnaces were a very popular means of heating a home in Eatonville. Instead of pressurizing and blowing air through vents to each room of your home, a gravity furnace used gravity to move warm air between rooms.

The operation of these furnaces is pretty simple. When turned on, the furnace, which is located in your basement, burns fuel like gas or oil and produces heat. That heat is vented through ductwork to the top level of your home using the natural properties of gravity (hot air rises). The hot air exits vents as it travels up in the home and releases heat into the room.

Why to Replace a Gravity Furnace

While gravity furnaces can work nearly forever and have very few mechanical problems, they are incredibly expensive to operate and take up a lot of space. Due to the sheer volume of ducts needed to distribute air throughout your home and the cost of heating enough air to ensure it rises properly, you’re dealing with a heating efficiency of 50% or lower.

In fact, about half the energy you consume to heat air in a gravity furnace gets pumped straight out through the chimney. It’s a complete waste of money and a heating system replacement will start saving you money almost immediately.

Newer furnaces have efficiency ratings of up to 95% which makes them nearly twice as efficient as gravity furnaces. Additionally, they take up less space and with modern components, you can install newer devices like zone controls, electronic readout and display and more. It’s a fantastic way to enjoy steady, reliable heat in your home without having to invest a fortune in the fuel needed to operate it.

Comfort Matters

Another thing to consider is the comfort level of your home. Because gravity furnaces release warm air through the middle of the house and cold air comes back down along the walls, homes that have them are rarely comfortable except in the middle of the house. Forced air furnaces with blower fans are much more efficient at distributing heated air and matching the thermostat settings you select.  Please call Sound Heating to get started today.

Tacoma Heating Repair Question: Why is My Furnace Making Noise?

April 2nd, 2012

During a bitterly cold night, in the luxury of our homes, we have the ability to adjust the temperatures to comfortably walk barefoot down the hall.  It is easy to take our Tacoma furnaces for granted, but without proper maintenance, they can become noisy and irritable, growling with mysterious sounds of dissatisfaction and ominous groans, warning that slippers and more blankets may soon be necessary.

This does not have to happen to you.

At the beginning of each season, it makes good sense to care for the furnace that is going to take care of you.   Scheduling an annual inspection and filter change with Sound Heating & Air Conditioning Inc. ensures a longer life and more comfort.

Rattles and Bumps in the Night

At the first sound of trouble, checking the filter can often be a quick relief.  As air passes through the furnace, a filter picks out much of the dust and some heavier particles that have come along, gotten snagged and accumulated over time to create a solid blockage.

This filter can become clogged and force your Tacoma furnace to work much harder to push the air through the blocked passage. Located just inside the front panel of the furnace, the filter is very accessible and easily exchanged for a clean one.  This should be the very minimum of regular maintenance and is simple enough to do that it can make anyone feel handy.

Deeper Trouble

Heated air and cold air returning to and from the furnace travel through ductwork which is often metal (those long, silvery boxes tucked up between joists in your basement and covered by a nasty layer of cobwebs).  The vibration of footsteps across the floor overhead or even of just the air movement through the ducts can loosen the fasteners and rattle the metal like a rumble of thunder.

Internally, there are fans and lots of moving parts in the motor.  A noise coming from this area portends a repair of a more complicated nature and should have the inspection of a certified technician, a service easily provided by Sound Heating.

With proper care and maintenance, furnaces are built to last for decades, providing heat and comfort to the home or office and improving the quality of life for the people inside.  Consult with experts to ensure the efficient operation.

Pierce County Q/A: What Exactly Are High Efficiency Boilers?

March 28th, 2012

As a Pierce County resident you have already read plenty about how energy costs are rising for most heating systems. You know plenty well that heating your home is a substantial expense, and that the cost of running a boiler is constantly on the rise.

But as technology has gotten better, boilers in Pierce County have also 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, call Sound Heating today!

Different Types of Furnace Filters for Lacey Residents

March 22nd, 2012

A good filter for your furnace is a must. Because that device heats and blows air throughout your home, you want to be sure that it doesn’t recycle contaminants and bacteria that could easily be captured at the air handler. By choosing the right filter you also contribute to your overall heating system maintenance over time.  That’s why it’s vital to choose the right furnace filter on the first try. Here are some furnace filters to consider and their various benefits to your home and family:

  • Electrostatic – Most electrostatic filters are permanent and must be washed on a regular basis. They are electronically charged to capture particles as they pass through, much like a magnet. These filters are effective because they are both physical and electronic. However, keep in mind that they are only as efficient as the cleaning they receive.
  • HEPA – HEPA is the highest rating available for a filtration system, removing up to 99.9% of all particles as small as 0.3 microns. However, they are also inefficient when used in furnaces as they severely reduce air flow. They are not often recommended for this reason.
  • Pleated – Pleated filters come in both reusable and permanent forms and can be either purely mechanical or electrostatic. There is a very wide range of efficiency ratings for pleated filters so make sure you analyze your home’s specific needs before selecting any one pleated filter.
  • Activated Carbon – Activated carbon is unique from the other three filter types because it effectively removes fumes, odors and chemicals from indoor air along with other larger particles. It is recommended that if you choose an activated carbon filter, you supplement it with a pleated or electrostatic filter (or choose a combination filter) to remove all unwanted components from your home.

There are a lot of options when it comes to furnace filters. To make sure you get only the best air quality, call Sound Heating and we can help you determine which pollutants are the biggest problem in your home.

Federal Energy Efficiency Rebates Explained for Tacoma

March 16th, 2012

As a Tacoma resident you’ve probably seen the advertisements and heard the sales pitches. Upgrade with a heating system installation, air conditioner, tankless water heater, or insulation and receive a federal rebate on your taxes for a percentage of the installation cost. The government is seriously invested in improving the energy efficiency of the country, cutting electric bills and helping people stay comfortable. Here’s a quick look at some of those rebates and how you can tap into them.

Energy Efficiency Credits

There is a standard tax credit of 10% of the cost up to $500 or a specific amount between $50 and $300 for any upgrade made to your existing home for heating, ventilation, air conditioning, insulation, roofs, or water heaters. These upgrades must be made on an existing home in which you currently live – rentals and new construction homes are not eligible.

Green Energy Credits

Even better credits are available if you plan on installing a geothermal heat pump, wind turbine or solar system – either PV panels or solar heating. The tax credit here is 30% of the cost with no upper limit. This applies to any existing or new homes and can be applied to both primary and secondary residences.

Are the Tax Credits Worth It?

The big question is whether these credits are worth the investment in a brand new system? For the most part, it depends on your particular situation. If you have a 30 year old furnace and are planning on an upgrade anyways, why not take advantage of a nice rebate and get a more energy efficient system to go with it? However, if you just replaced your furnace three years ago and it works very well with a high energy efficiency rating, it might not be worth the investment.
