The Preventative Maintenance That Will Save You the Most on your HVAC System

Friday, September 16th, 2011

Having a high performance, energy efficient HVAC system will save you a good deal of money in terms of your monthly heating and cooling bills in Estacada. But that efficiency will not last unless you also take the necessary steps to keep your equipment in good working order. While regular maintenance visits from a professional HVAC technician are an important part of this, there are also several things you can do on your own to keep your equipment running at peak efficiency.

  1. Keep it Clear – The first thing you should do is to make sure that there is plenty of space cleared around your outdoor unit. Whether it is the condenser and compressor for your air conditioning system or part of your heat pump, that outdoor equipment needs to have plenty of space to vent hot air. Also, the space will mean that debris is less likely to develop inside the unit.
  2. Clean the Condensing Coil – While your technician will do this when they make their annual visit, it is best to clean your coil more than just once a year. Just make sure that the power is turned off to your unit before you begin. This will help the unit cool air more efficiently and can prevent a whole host of other problems from developing.
  3. Check on the Blower – If your blower is not working right or the blade is clogged, your HVAC unit will not work properly. Make sure your blower fan is free of all debris and that is turns freely once you have cleaned it. If you are still having a problem with it, you may have to call a technician for repairs. Cleaning the blower out on a regular basis, however, should keep this from becoming a problem you need a professional for.
  4. Air Filters – You should also make sure you change your air filters regularly. This can help to keep your indoor air clean and healthy and it will also enable your HVAC system to run more efficiently.
  5. Clean it Out – Clean out any debris that you can reach from any part of your system. Just make sure any time you work inside your HVAC system that you have all of the power turned off. Anything from leaves to dust can get in there and cause a problem if it is allowed to build up over time. As long as you are on top of things and keep to a regular schedule of maintenance, none of this should take you very long.

Air Conditioners and Energy Use by Percentage

Wednesday, August 31st, 2011

It’s no secret that air conditioners use up a lot of electricity and can add substantially to your energy bills during those warm summer months in West Linn. But did you know that all air conditioners actually account for an estimated 11% of the total energy used in all buildings in the US each year? This is a staggering figure and makes it easy to see why it’s best to invest in the most energy efficient system possible.

Keeping Your Consumption Down

There are plenty of reasons to try and keep your energy consumption down. You want to save on your energy bills, and the less energy you use, the better it is for the environment. The best and most straightforward way to go about this is to purchase only highly energy efficient appliances and equipment, and that includes air conditioners.

Because air conditioner usage accounts for such a substantial part of the total energy used in this country, putting more energy efficiency models into use is the best way to cut that usage down.

Supplementary Cooling

However, there are other ways to reduce the workload of your air conditioner. For instance, you can use a ceiling fan to maintain good air circulation and keep your home cool. Using a ceiling fan with an air conditioner, even on the hottest days of the year, allows you to turn up your thermostat a bit to conserve energy while still enjoying a comfortable indoor environment. And because ceiling fans use so little energy to operate, you’ll come out ahead on your energy bill.

Passive Cooling

There are also several passive cooling methods you can employ to keep the temperature in your home down. Blocking out sunlight is the most important of these, so keep your blinds closed on any windows that receive direct sunlight, particularly in the early afternoon. Alternately, you can have awnings put up, which allow you to block the direct sun while still keeping the blinds open.

Shade is another effective passive cooling device. Planting trees around your home to block out the sun at the hottest times of day is a totally energy-free way of keeping your home cool and reducing the workload on your air conditioning system. The less your air conditioner has to work, the less energy it consumes and the lower your energy bills will be.

Who Invented Air Conditioning?

Friday, August 26th, 2011

For hundreds of years, people have been trying to figure out how to stay cool in the heat of the summer. 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 Troutdale 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. For more information about modern air conditioners, contact your local HVAC contractor.

The Energy Efficiency Rating of Central Air Conditioners: Why is this important?

Wednesday, August 24th, 2011

When you are shopping for a central air conditioning system in Estacada, you will have to evaluate your options based on a number of different factors. For instance, you will need to decide which type of system is the best match for your home and for your particular cooling needs. It is also important to make sure that the central air conditioner you choose is the right size for the cooling load it will have to take on.

However, it is also very important to evaluate your central air conditioning options based on how energy efficient they are. This will have a great deal to do with how much you pay in terms of cooling costs each month, which makes it easy to see why you should take it into account before you make a purchase.

The energy efficiency of a central air conditioner is generally expressed as a seasonal energy efficiency rating, or SEER. The SEER numbers you will typically find on the latest air conditioning systems range from eight to 19.5 with the higher numbers signifying a more energy efficient model.

So it is pretty easy to figure out that a central air conditioner with a higher SEER will save you some money monthly because it will use less energy to get the same job done. But central air conditioners with high SEERs also typically have high price tags. So to determine how high of a SEER you need, you will need to know more exactly how much more money you will save as you move up in the rankings.

You can do this by comparing the SEER of the system you currently use with the new system you are considering and compare how much your current energy usage would cost you with each model. Basically, you want to pick a central air conditioner that will save you enough to offset the purchase price of the unit.

Often, this means that you will be best off with a SEER 14 or SEER 16 because these units save you a considerable amount over older models without carrying too high a purchase price. However, the amount you save will be directly related to how much you use your central air conditioning system, so if you live someplace that is extremely hot for a large chunk of the year, it may be worth it for you to buy a very high efficiency air conditioning system.

Different Types of Room Air Conditioners

Monday, August 1st, 2011

If you are like most people in Happy Valley, you probably picture the air conditioner hanging out of the window when you think of room air conditioners. However, while these are by far the most popular type of room air conditioners, they are not the only option. When you are shopping for a room air conditioner, it is a good idea to explore all of your options before you make a purchase.

The traditional window mounted air conditioners have plenty of advantages, and that has helped to keep them at the top of the room air conditioner market for a long time. These types of units can be installed in windows of multiple sizes and you can just about always get them in yourself. These units are available in a wide variety of sizes too, so you will be able to match the unit to the size of the space you need to cool.

No matter what type of air conditioner you get, it is very important to make sure it is the right size for the task you have laid out for it. Bigger is not always better and you do not want an air conditioner that is too powerful for the space any more than you want one that is too small. Also, be sure to check the energy efficiency rating of the air conditioner you are considering before making your purchase. That can save you a lot of money over time as well.

Another type of room air conditioner to take a look at is a wall mounted unit. Many of the window mounted units can actually be used in this way as well, but the installation involves actually making a hole in the outer wall of your home so you will most likely need some professional help to get it in place.

Just like window mounted units, wall mounted air conditioners come in all sizes and with all different energy efficiency ratings. Always take care to check out the specifics of the model before you buy it to make sure it is the right choice for your home.

Portable air conditioners are a third option in the room air conditioner category. They typically have wheels so that they can be easily moved from one room to another and they have an exhaust hose that must be hooked up to a window to ensure adequate ventilation. These types of room air conditioners are usually more expensive than wall or window mounted units, but it is definitely convenient to be able to move them from one place to another. If you have more questions, contact your local air conditioning professional.

What Is a Whole House Pressurization Test and Should I Get One?

Monday, July 18th, 2011

If you have a forced air heating or cooling system in your home, you also have a system of ducts through which that heated or cooled air circulates. And most people don’t give a second though to those ducts. After all, if your heating and cooling systems are working, the ducts must be doing their job, right?

Unfortunately, that’s not always the case. If ducts are not working properly, the whole system will be in trouble, even when you don’t realize there is a problem. That’s why a pressurization test is so important – it provides peace of mind knowing that your home’s ductwork is not only properly installed, but that it doesn’t need any special repairs.

Why Pressure Matters

Your duct system depends on proper pressurization to evenly and efficiently distribute air throughout your home. Leaks, cracks or clogs in the system can disrupt that pressure and lead to uneven or inadequate movement of air through your ducts. This causes problems you may not notice, so if you haven’t had your ducts checked for proper pressure in a while, it’s worth looking into.

Improper pressurization causes symptoms like hot or cold spots in your home or an overall drop in the effectiveness of your home heating and cooling system. When loss of pressure is due to a leak that lets in unfiltered air from outdoors it can also lead to a decrease in indoor air quality. Often these symptoms are easy to ignore. But by doing so, you only allow the situation to get worse.

A whole house pressurization test is the best way to determine the state of your home duct system. By using high tech diagnostic equipment, home HVAC professionals check over your entire system to determine whether you have a pressurization problem. If so they can then quickly pinpoint the source. Once that’s done, the repairs are usually quite simple and you’ll get much more out of your home heating and cooling system than you did before.

Even if no symptoms of improper pressurization in your ducts have presented themselves, it’s worth having one of these tests performed. Especially if you don’t know when the system was last checked, a whole house pressurization test can help uncover small problems before they turn into bigger ones. And the peace of mind this provides is well worth the day it takes to perform the test.
