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.

Why Are Clean Filters So Important to AC Efficiency?

Tuesday, February 28th, 2012

Air conditioners cost a lot of money to operate in Seattle – even more when they don’t work at 100% efficiency. So, it is important to perform the various regular air conditioning maintenance tasks that ensure the system uses as little electricity as possible. The first thing on your list (and the easiest) is cleaning those filters.

Keeping Filters Clean

The Department of Energy’s Energy Savers website states that you can reduce your air conditioner’s energy consumption by as much as 15% simply by keeping the air filters clean. Why do they matter so much? Consider the nature of a filter.

The filter on your AC unit is designed to capture any dust, debris and sediment in the air supply. If that dust and sediment was allowed in, not only would it gum up the mechanical workings of the device, it would get into your ductwork and reduce the air quality of your home. So, filters are used to capture such things. However, when a filter gets clogged, the system must work harder to draw the air in. As it works harder, the motor turns faster and more electricity is used.

It takes very little to clog the filter of an AC unit, especially if it is running 24 hours a day for two or three months out of the year. So, it’s best to check your filters once every 30 days regardless of what type of filter you are using.

Which Filters to Check

The main filter on your AC unit should be checked along with any air handler filters and any air cleaner filters you have installed in your system. Another thing to consider is the condition of your home and the area around your outdoor condenser. If you have pets, lots of plants or your condenser is located in a dusty area, you may need to check and change those filters even more often.

Most filters are located along the return length of the ductwork – sometimes in ceiling ducts and walls, though they may also be located in your furnace’s air handler or inside the air conditioning unit. If you have window units or mini splits, the filters are frequently in the unit.

Clean air filters are important for your health, your wallet and the longevity of your AC system. Stay on top of them and you will save money in more ways than you might expect. Please contact Sound Heating if you have any questions.

Heating Q/A: Can Your Heating System Warn You of a CO Leak?

Wednesday, February 22nd, 2012

Carbon monoxide is a serious health risk, even in Tacoma. It is an odorless gas that is produced as a natural byproduct of combustion. So, any time something burns, carbon monoxide (CO) is released into the air.

As long as heating installation is properly ventilated, the carbon monoxide cannot build up in the air to a dangerous level of concentration. For example, if you are around a campfire or charcoal that is burning outside, you are generally safe.

In the home, the danger arises when combustion is not properly ventilated and this toxic gas is allowed to seep into our living spaces. If you use any gas, fuel or wood burning appliances in your home, you are at risk for exposure to carbon monoxide. To help mitigate that risk, it is important to know some warning signs. Your heating system gives off some warnings that can tip you off to danger, so be on the lookout for these three signals:

Carbon monoxide detector goes off. Some heating systems these days have built-in carbon monoxide detectors, which can provide an extra measure of safety. Whether you have one of these systems or not, your home should still be equipped with a CO detector. If it begins sounding the alarm, get everyone out of the house immediately.

A fume vent is leaking. Fuel-burning furnaces have vents to move combustion gases out of the house safely. If you notice this vent is leaking on your heating system, CO may be seeping into your house. Shut down the furnace, open windows for ventilation and have the fume vent repaired immediately.

Smoke backing up from the fireplace. If you have a fireplace and you notice smoke in the room while using it, stop using it immediately. Your chimney may be blocked or leaking, preventing the smoke from rising and venting properly, which means CO can e getting into your house. Do not use the fireplace again until you have had the chimney inspected.

Please take care and note this is just a simple guide. There are other risks and warnings of carbon monoxide. If you have any suspicion that there is CO in your home, immediately call Sound Heating to look into the situation.

HVAC Tips: What is an Electric Furnace?

Friday, February 17th, 2012

There are many types of furnaces for Covington homes that use a variety of energy sources to operate. Gas furnaces use natural or propane gas, boilers and radiators use water, heated by electricity. And then there are electric furnaces, which may have an advantage over other energy sources based on energy costs.

Simply put, electric furnaces function through the use of electricity. They do not require the use of any type of fuel – but function through wires and chords. An electric furnace uses heating coils, sometimes referred to as “resistance calrods” to create heat directly in the air flow. Inside the furnace cabinet are controls, a blower, and the circuit breakers for the heating elements. Some furnaces have the breakers accessible from the outside of the cabinet.

Other add-on accessories may include an electronic air cleaner, air filter, humidifier, high performance media filter, and air conditioning evaporator coil.

The heating process begins with the home’s thermostat. A drop in temperature is sensed by the thermostat, which alerts the electric furnace. The coil then warms up, thanks to the electric current that passes through it. The heated coil in turn heats the temperature of the air around it, which is then blown into the house through a blower. The pressure that is exerted by the blower on the heated air, warms it further. The blower is able to overcome the resistance of the duct work and replace unheated, colder air with the heated air. In most homes there are various return air ducts that are used to bring in the colder air to the furnace. This cold air travels through the furnace, through an air filter, the blower, and finally through the heat exchanger. After this it will then be pushed back into the house as warm air.

To maintain a supply of fresh air in the house, some furnaces also suck air from the atmosphere outside. After the air in the house reaches a particular temperature, the thermostat automatically shuts off the electric furnace.

An electric furnace may be less costly to run, depending on the price of electricity versus other sources like natural gas, propane gas, or oil. Gas and oil are fossil fuels and burning them leaves a “carbon footprint” – the release of carbon compounds and gases into the atmosphere. An electric furnace does not burn fuel and thus does not leave a carbon footprint. This electric warming process results in fewer particulates and contaminants in the air, too. If you have any questions about this topic please call Sound Heating.

The Most Effective Environmentally Friendly Heating Methods

Monday, February 13th, 2012

Protecting the environment is a priority for many Puyallup homeowners these days. The problem is that it can’t be as a high a priority as heating your home. Sure, you want your home to be environmentally friendly, but you need it to be warm.

So, it seems you are forced to run your electric or fuel-powered furnace as much as is necessary and hope that it’s not too much for the environment — or your wallet — to take.

Beyond the traditional heating methods of electricity, gas, oil and what have you, there are some alternatives out on the market these days that can keep your home warm while also being green.

Geothermal

One solution is geothermal heat, which harnesses the natural heat of the Earth to warm your home. Pipes filled with coolant run through the ground outside your home, absorbing the warmth of the Earth. Then, the warm coolant is pumped into your home through a network of pipes that radiate heat.

This method is effective and requires no additional fuel or energy.

Micro Combined Heat and Power (MCHP) Systems

Relatively new to the game are so-called MCHP systems. These heating systems have on-board power generators with high-efficiency computer modules attached. The power module interfaces with the thermostat, calling for heat when necessary. That activates the generator system, which quietly and efficiently generates all the necessary power to run the heater.

These systems are incredibly efficient and can slash the cost of your heating bill. As an added benefit, they continue to work during power outages, which has obvious utility in areas that experience harsh winter storms.

Solar

Then, of course, there is the most obvious and readily available source of heat to the whole planet: the sun. Solar heating systems can be either active or passive, which essentially just depends on whether additional specialized equipment is to be installed.

Obviously, solar heating systems are a better choice for areas that get a lot of sunlight year round.

Whichever environmentally friendly heating solution you choose, they have the added benefit of lowering your heating bill, which is always welcome. If you have any questions about these environmentally friendly heating methods please contact Sound Heat & AC

Get Rid of the Icicles on Your Eaves in Des Moines

Friday, February 10th, 2012

There’s nothing more impressive than a particularly long icicle on the eaves of your Des Moines home. As it reaches toward the ground, dripping cold water, you can’t help but think of starting up your furnace. However, icicles are often unsafe – not only for you and your family but for anyone else that might be near your home. As more water joins the icicle and the structure grows, it gets heavier. That weight heightens the chance that it will fall and hit someone or that it will cause damage to your roof or gutter.

So, it’s important to get rid of icicles on your eaves as they appear. Generally, it is best to remove them before they reach 4 or 5 inches in length. Even shorter icicles can be dangerous if left unchecked and if anything is stored underneath the overhang of your roof, it can be damaged.

Removing Icicles

There are quite a few ways to remove icicles. The easiest way to is to cut or break them down. If your roof is low enough, you can hack them down with a large saw or knife. If the roof is higher, a board or broom can be used to reach up and knock them down. In the winter, you should do your best to avoid going on the roof to remove icicles. The danger involved is too great due to ice and snow.

Another way to remove icicles is with heat. There are a few ways to do this. A blowtorch or heated rod provided by a roofing company can help to remove them from the ground. Or you can install heating panels on your eaves and gutter that will keep those icicles from forming in the first place.

Safe Removal

When removing the icicles from your roof, make sure you carefully rope off the area and don’t allow anyone nearby. You should wear a helmet if you plan on standing below them and try to stand clear of the fall area. Icicles are very sharp and incredibly solid – they can cause horrific injury if you’re not careful.

Ideally, if you act fast, icicle removal is just a minor inconvenience every weekend. However, if the icicles form up too heavily and become a physical danger to people in and around your home, you should contact a professional with tools that can remove them quickly and safely without putting anyone at increased risk. If you have any questions about this please contact Sound Heating & AC.

Heat Pump Maintenance in Renton

Wednesday, February 8th, 2012

Heating and cooling your Renton home is a priority. You need your home and family to be comfortable all year round, so you either got or are considering a heat pump. These machines are great because under the right circumstances, they are essentially all-inclusive and incredibly efficient solutions for all your home heating and cooling needs.

Notice the “under the right circumstances” part. A number of things have to be considered when choosing a heat pump, such as the climate and the size of your home. But these are not the only circumstances that influence how well your heat pump works for you. Proper heat system maintenance is a vital component of heat pump ownership, ensuring that you get the best performance out of your heat pump for the longest time possible.

A major part of properly maintaining any machine is to keep it clean. A heat pump is no exception. Dirt and dust can affect the efficiency of your heat pump, as well as speed up corrosion problems. Keep the compressor and coils clean. Check them monthly or so and remove any accumulated dirt. Also, consistently check and change filters according to the manufacturer’s recommendations.

Simple cleaning is an easy and effective first step to heat pump maintenance, but there are some things that you just won’t be able to do on your own. For more intensive maintenance, it is best to call in a professional for an annual inspection.

During a routine maintenance check of your heat pump, a technician will inspect the whole heat pump system for problems. He will clean the compressor and coils, tighten any connections that may have loosened up and change the filters as needed. In addition, a skilled technician will be able to detect any early signs of trouble and make necessary repairs to prevent break downs. These small repairs can prevent big problems later on, thereby preventing some serious discomfort and a possible big expense.

If you are considering a heat pump as a heating and cooling solution for your home, great. If you have already decided on one and had it installed, congratulations on making a smart decision. Now, make another smart decision to protect that investment by keeping your new heat pump properly maintained. Please call Sound Heating & Air Conditioning with any questions.

When Is it Time for a Backup Heating System?

Monday, January 30th, 2012

A backup heating system is sometimes necessary for Tacoma homeowners who heat their homes with an air-source heat pump. This style of heat pump transfers the heat from the outside air to your home in the winter, and it pushes the warm air outside the home in the summer. Although some systems are efficient enough to work in colder climates, most heat pump systems require a backup heater when temperatures drop below 20° F.

York Furnaces are commonly used as a backup heater for air-source heat pumps, especially since the furnace fan blower can help distribute the hot air throughout the home. Although they are more expensive to buy and install, geothermal heat pumps typically do not require a backup heating system. These are also called ground-source or water-source heat pumps since they draw in heat from the ground below the house or from a nearby water source. Because they take advantage of the ground or water temperatures, they are also easier to maintain and have lower operating costs.

Getting the most cost-efficiency from a geothermal heat pump will depend on several factors, such as the size of your property, the temps of the subsoil, and access to local water sources. You will most likely not have to install a backup heating system with a ground-source or water-source heat pump; however, it is important to think about the installation costs and the variables that need to be in place before deciding on this type of heat pump.

Absorption heat pumps use a heat source, such as natural gas or solar-heated water, instead of electricity. Natural gas is typically used for absorption heat pumps, so they are also called gas-fired heat pumps. Depending on the source of the heat, you may or may not need a backup heating system. It’s always best to speak to a professional heating and cooling contractor if you are not sure when it’s necessary for a backup heating system.

Call Sound Heating if you have any questions about a backup heater for your Tacoma home.

Steilacoom Boiler Guide: Basic Maintenance

Friday, January 20th, 2012

The boiler in your Steilacoom home is a sensitive piece of equipment that needs routine maintenance and repairs. Regularly maintaining your boiler is especially important for safety reasons. Many boiler malfunctions and accidents are due to neglecting some of these basic tasks.

Even if you’ve just installed a new boiler, the safety valves and settings should be checked by a professional on a regular basis to prevent a breakdown or hazard. We recommend that you schedule a boiler inspection and cleaning at least once a year.

A service technician will measure the pressure, drain and remove sediment buildup, test the efficiency ratings, and make sure your boiler is set at the right temperatures. Regular maintenance can also help you determine whether or not you need a boiler replacement. By keeping track of performance levels, you will be able to tell when it’s time for an upgrade.

Other tasks performed during an annual maintenance visit include cleaning and lubricating all the components, checking for any leaks or clogs, and testing gas boilers for any carbon monoxide intrusion. If you have any gas appliances in your home, you should always have carbon monoxide detectors and test them once a month.

Boiler pressure is something that you can check often on your own. If you aren’t sure how to read the pressure gauge, or if you aren’t sure what the right pressure should be, just call one of our technicians to walk you through this process.

Always call Sound Heating & Air Conditioning Inc. if you have any problems with the boiler in your Steilacoom home. We are here to help and answer any questions you may have.

Heating Installation Tip: Load Calculations

Friday, January 13th, 2012

Do you ever feel that your Kent 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 and the furnace in your basement should be making your home as comfortable as possible. 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? Call a Kent HVAC contractor and ask for an energy audit for your home. The audit will include several key checks 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. An energy audit 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. Your HVAC contractor may also factor in the number of building occupants and normal usage patterns, i.e. having a home office or stay-at-home parent versus a working family where your home is occupied mostly at nights or on weekends.

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.

Make sure you don’t hire someone who “guesstimates” how much cooling or heating capacity you need for your home. Find a qualified professional who will make the correct calculations and who will qualify their recommendations. A properly sized HVAC system will equate to manageable utility bills and above average indoor comfort. You can live with that.
