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.

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

Kirkland Air Conditioning Tips: How to Clean Your Outdoor HVAC Unit

Friday, February 3rd, 2012

That big metal box in your backyard or on the side next to your Kirkland home plays a vital role in air conditioning your home and keeping you comfortable. That box is called the outdoor condensing unit, the key component in your home’s central air conditioning system. The condensing unit houses the compressor, which converts gas into fluid before sending it to the condenser coil, where it is cooled and sent to an indoor evaporator coil.

What you need to know is that the entire outdoor operation runs smoothly when the area inside and around the condensing unit is clean and free of debris. In some cases, the outdoor unit will fail to work if there is too much debris or dirt build-up. That can cost you a lot of money in repairs or a total replacement. Keeping the condensing unit clean is not a difficult chore – and here are some steps you can take.

First of all, try and avoid blowing leaves or grass clippings near the unit. And regularly cut down or remove any weeds or grass that may grow up around the base of the unit.

To clean the inside of the unit, first turn off the electrical power to it. Check for an on-off switch on the unit or on a separate box nearby. Remove the grille from the unit and carefully remove the fan in order to gain access to the coil and other moving parts. At this point, you should be able to clean out any debris from inside the unit using your hands. You can also use a vacuum hose to remove debris. A soft brush or cloth rag can be used to other areas of the HVAC unit.

The fins on the coil require a gentler approach as they can be easily bent or damaged. If you notice a bent fin you can straighten it out by using a simple dull knife or a special fin “comb” which you can buy at your local hardware store. While you are in the unit, check the fan belt on the motor to ensure it is not damaged or cracked. You can also add extra oil to lubrication ports on the condensing unit, if any are available.

Use a garden hose to clean the coil and the grilles on the condensing unit. Do not use highly-pressurized water as it may cause some damage to the fins. Once this last task has been completed, reinstall the grille, switch on the condensing unit, and start up your air conditioning. You should notice if your house is cooling down quicker. If not, you may want to do some more cleaning.

If you have any doubts about cleaning your outdoor condensing unit or if you find any damaged parts that may need repair or replacement, call your local qualified heating and cooling (HVAC) contractor and schedule a service call.

Good luck – and stay cool.

How Many Solar Panels Do I Need For An Electric Solar Power System in Tacoma?

Wednesday, February 1st, 2012

Aside from determining cost, knowing how many solar panels you need to potentially power your home in Tacoma helps you picture what the finished product will look like. After all, you want your home to be energy efficient, but you also want it to not be an eye sore. Estimating how many panels you will need involves some research and math, but it can be done simply enough and is worthwhile. Below are some steps to help you estimate how big your array will need to be:

Researching Solar Panels

First up, decide how much of your energy needs you want a solar array to provide. For example, you may choose to keep your home on the utility grid, but plan to have 50% of your home’s energy come from solar. The steps below assume 100% solar energy.

You should also determine your current energy usage. You can do this by looking at old utility bills. It is best to look at usage over a span of 6-12 months in order to get an accurate estimate. You will usually find this figure in kilowatt hours (kWh). Estimated energy use for an average American household is about 740 kWh per month.

Another important step is to find the insolation value for your area. This number reflects the number of hours in a day that a solar panel will perform as rated. You can find reference tables of insolation values online.

Calculations for Your Solar Panels

Now comes the fun part – a little bit of math. First, you need to figure out the desired wattage output of your system. To do this, divide the number of kWh to be produced in one day and divide it by the insolation value. Using the average monthly usage from your research, you can see the daily average usage is about 24 kWh per day. With an insolation value of 4 hours (for example), a solar array needs to generate 6 kilowatts per hour. Because the system is not 100% efficient, raise that value by 30% to account for possible energy loss. This system will need to generate 7.8 kilowatts per hour. Since large solar panels produce about 130 watts per hour each, this system would require about 60 panels.

Note that this is an extreme example, as most homes won’t use solar for 100% of their energy needs. You will almost certainly use fewer panels; these steps are just meant to help walk you through the process. There are also calculators available online to make the estimation process a little simpler.

Is Your Kent Home More Valuable with Energy Efficient Appliances?

Monday, November 28th, 2011

It’s impressive the things people do to improve the value of their Kent home. We’re talking about crown molding, new floors, new siding, upgrades to the landscaping and much more. The cost of upgrading these things can grow out of hand quickly and if the boost to your home’s value isn’t equally exponential, it’s hard to justify the expense.

So, it’s always nice to find a simple upgrade that can be performed for a few hundred dollars that will save you money immediately and improve the value of your home in the future. Your appliances are one such upgrade.

The Value of Energy Efficiency

An energy efficient washing machine can save upwards of $150 per year on water costs. An energy efficient toilet cuts consumption by as much as 150%. Low flow shower heads cut water costs by one third to one half and your heating and air conditioning systems can be improved by 10-35% depending on the upgrades available to you.

When you add up all those savings, the result is a tremendous amount of money that can be saved each year on everything from your water bill to your cooling needs. Imagine what happens when someone looks to buy your home. They see that there are all new appliances with energy efficient ratings that will save them money.

It’s not just lower bills; it’s a decrease in upfront investment. On the surface, it’s unlikely that your energy efficient appliances will directly increase the value of your home, but they can increase the likelihood of someone paying what you’re asking for the home. They add value to the livability of the home, if not the property itself and in today’s housing market, that’s a major plus.

Best Upgrades

The best upgrades to your home’s appliances are the ones that save money without additional work. Water saving appliances should top your list since they are used throughout the year. A new toilet, a new washing machine, a new shower head and sink faucets all designed to cut down on water use are valuable upgrades. Major upgrades to your heating and cooling are good if you need an upgrade anyway or you plan on staying in your home for a few years.

To Zone or Not to Zone My Home Comfort: A Tip From Bellevue

Monday, September 19th, 2011

There are a lot of decisions to make related to your Bellevue home’s comfort system. You must decide what type of heating you want, how you’ll implement air conditioning, and then how to keep all of that heated and cooled air clean and healthy in your home.

On top of everything else, you have the option to implement zone control in your house to provide multiple comfort levels for each member of your family. Zone control systems are growing rapidly in popularity because they allow home owners to enjoy an enhanced level of comfort throughout the day, while not negatively impacting any one person.

For example, if it’s chilly outside and you need to turn your heater on, that doesn’t mean everyone in the house wants the thermostat set to 72°F. There are a few reasons for this. You may be in the kitchen, working over the stove or doing dishes where there is plenty of heat to keep you warm. More warm air coming through vents or radiators isn’t going to make you comfortable.

The second floor of a home traditionally needs less heat because warm air on the first floor rises and fills that space. The same is true in the summer when cool air settles in lower floors. Having a zone control system allows you to set specific temperatures in each room which are then controlled by your home heating system. You can even turn off the heating and cooling in a specific room like your office or the attic if it will be empty for long periods of time.

Other Considerations

A zone control system is good for comfort, but also for the overall air quality of your home. Too much conditioned air moving through your ducts carries more allergens and contaminants into your home and causes your air quality system to work harder. Your ventilation system will be asked to work harder as well.

Ideally, a good home air quality system is designed to use as little conditioned air as possible to keep everyone comfortable. A zone control system does this very effectively. When talking to a professional about a new installation, check to find out about programmable thermostats as well. These can make it easier to set and forget the temperature in rooms that are only used for a few hours each day.

How a Thermostat Works: A Guide From Covington

Wednesday, September 14th, 2011

Your thermostat is designed to closely monitor and maintain the temperature in your Covington home. When you flip the switch, you want your furnace or air conditioner to respond immediately. So, it’s a good idea to learn how it works so that if there is a problem, not only will you know better what needs to be fixed – you can decide whether to call a professional in for help.

Thermostats shouldn’t need input from you other than to set the initial temperature. From there, they are automatic switches. A thermometer inside the thermostat measures the indoor air temperature. When it gets above or below the limit you’ve specified, it triggers the thermostat to send a message to your home comfort system and keep things nice and comfortable.

Types of Thermostat

Thermostats come in two forms –electromechanical and electronic. An electromechanical thermostat is the simplest and has been used for decades to regulate temperature in homes. It has a simple strip or coil of metal that expands as the temperature rises and contract as it lowers. A mercury thermometer is placed on top of the strip. The coil’s movements cause the vial to tip as the temperature changes. There is a pair of electrical contacts on either end of the vial. The mercury can absorb that electrical current when the electrical contacts touch the thermometer. The mercury then acts as a switch to turn on your comfort system.

An electronic thermostat simply has an electronic sensor that measures the indoor air temperature. You set a temperature for your room and when it changes significantly, the switch inside your electronic thermostat is triggered, causing it to turn on your comfort system.

Ways to Upgrade Your Thermostat

Most homes only need the bare minimum in their thermostats. However, there is some very exciting technology on the market these days that can add quite a bit of value to your system. Not only can you install a programmable thermostat, you can opt for zone control systems that allow multiple thermostats in different rooms of your home.

Programming allows you to set temperatures for certain times of the day. This is especially great if you are gone from the house for long periods of time each day. Why heat or cool a home when it is empty? And if you have multiple people with different temperature needs, zone control temperature control allows you to set specific temperatures for specific rooms in your home – a very enticing option for large families or multi-story homes.

What to Look for when a Home is 50 Years Old

Monday, July 11th, 2011

Buying an older home can be a very rewarding experience. The architecture is unique, the rooms have character, and it feels more like a home than a brand new, prefabricated home that was built in a development. But, there are quite a few things to keep in mind when buying a house that is 50 years old or more – from what construction materials were used to how it was maintained for the last 50 years.

Possible Safety Issues

Because the dangers of lead paint and asbestos were not yet understood in the 1950s and ‘60s, you should always have your home thoroughly inspected for both before buying. The risk of either being in a 50 year old home is high unless someone has gone to the trouble of removing them in a remodel. Even then, older insulation, hidden paint layers or other construction decisions can be potentially dangerous, especially if you have children.

Not that you should avoid an older home solely for this reason. There are plenty of homes that have been made livable again with a little hard work – it’s just important that you know about it before investing so much money.

Maintenance Issues

Another thing to consider is the upkeep of the house. A 50 year old home has been lived in for many years. That means there have been multiple furnaces and air conditioners, replacements of windows, new roofs put in and much more. How well and how often those things were done will play a major role in determining how good of condition the house is in.

If you buy a 50 year old home and the roof and furnace need to be replaced, that’s another 5 figure investment to update your living space.

Other things you should be on the lookout for are old appliances like your refrigerator and stove, as well as the gas lines and electrical. Your panel box may be outdated, as may your electrical lines and outlets. These are all things that get updated eventually, but a home built 50 years ago would be both unsafe and outdated by today’s standards.

More than anything, when buying an old home, the most important thing is the condition. Age has very little to do with how livable a home is. Some people live comfortably in homes that are 200 years old. Others must have 10 year old homes completely remodeled. It’s all about how the home is maintained and cared for.

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.

Maintenance Really Does Save Money

Wednesday, June 29th, 2011

When it comes to your home heating and cooling systems, you really cannot go wrong with proper annual maintenance. While it may seem like an unnecessary expense, especially if your systems are relatively new, you will save a lot in the long run if you pay that small fee once a year for each system.

During a maintenance visit, a technician can thoroughly clean out your heating or cooling system and check all parts to make sure they are not showing signs of excessive wear and tear. If they do find a problem or a part that needs to be replaced, they will be able to make the necessary repairs quickly and you will not have to worry about calling someone out later for an emergency visit.

Also, catching problems early like this means that repairs will likely involve fewer parts and cost much less than they would if you let the problem go and it became more widespread. The truth is that your heating or cooling system can continue to work when one or another of its parts is not working correctly, but that means that other parts of the system have to work overtime to create the same result.

Your heating or cooling system will also be much more energy efficient if it receives regular tune ups and attention from a professional. Even the best new systems lose a small percentage of their efficiency each year that they are in operation. While this is not much from year to year, the cumulative effect will soon cause your energy bills to climb higher than necessary.

Paying for regular maintenance, then, can actually save you money because it will mean you pay less each month to run your system. And it is never too late to start. Even if your heating or cooling system is not new, it will benefit from a thorough cleaning and tune up. You may be quite surprised how much your energy bills go down after this type of service has been performed.

Annual maintenance can also help you to get more for your money by extending the useful life of the heating or cooling system. Many systems that are properly maintained can last even beyond their expected life span, meaning that you will not have to replace it as soon as you would have otherwise. For all of these reasons, the minimal cost of an annual maintenance visit is well worth paying over the long term.
