Does Humid Air Affect How The AC Runs in My Home?

Wednesday, February 22nd, 2012

As a Spokane County resident you’ve probably heard a dozen times that humidity is removed by air conditioning. Unfortunately, the common assumption is that there is no inherent cost in allowing humidity to persist in their home. But, did you know it costs significantly more to remove humidity from the air with air conditioning than with a dehumidifier? Here’s why.

Water Vapor in Your Air Conditioner

Consider the amount of energy it takes to raise the temperature of water by one degree – one BTU. However, to change water from liquid to steam, another 10 BTUs are required. So, imagine how much energy it takes to condense water vapor from the air (in the form of humidity) into a liquid. This is what your air conditioner does whenever it processes humid air. It takes about 1,050 BTUs to condense one pound of moisture in the air into liquid.

The cost of running your air conditioner strictly for dehumidification can be huge, especially considering the fact that humidity is heaviest in the morning and evening when you probably don’t need your air conditioner every day (at least not early and late in the summer). Imagine, the cost difference if you used a dehumidifier to remove 150 or more pounds of moisture per week and an air conditioner when needed just to remove 15-20.

Negative Impact on How it Runs

Another thing to consider is that humidity can actually put an extra burden on your air conditioner. While the system is designed to remove that liquid from the air and get rid of it through the cooling coil and condensate drain, every extra minute the system is running is a bigger burden on it. Of course it will do its job for a few years, but the extra running time will add up, not only on your electricity bill but eventually on the machine itself.

The added pressure will result in eventual breakdown of the system and a need for early air conditioner replacement. The easiest solution is to purchase a dehumidifier. These run at a fraction of the energy level of a full AC system and work extremely well to remove humidity from your home. In fact, most air conditioners will only remove humidity after 20-30 minutes of continuous operation. For short cooling cycles, you may not even dehumidify the house. So a dehumidifier ensures higher levels of comfort all at a lower cost.  Please contact ACI NW if you have questions about this.

Heat pump maintenance, the right way

Wednesday, February 1st, 2012

Heating and cooling your Spokane County 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 heating 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.

High Efficiency Furnaces and Chimney Concerns in Mead

Wednesday, December 7th, 2011

When upgrading to a high efficiency gas furnace, you may need to make some upgrades to your Mead home’s chimney. Older chimneys built for standard furnaces with normal exhaust needs are not built to the specifications needed by today’s high efficiency models. Not only is it unsafe to leave it as is, but the cost of repairs if you don’t have it upgraded can be substantial.

Down-Sizing

A common concern when upgrading to a high efficiency gas furnace is the issue of condensation and draft. Because the amount of exhaust being vented is reduced by a high efficiency furnace, your current setup is not sufficient for the new model. So, it needs to be reduced in size by a professional to avoid backup of exhaust. Proper chimney sizing is a complex process that requires professional guidelines and careful measurements of all appliances in your home.

Because the chimney often isn’t used at all for a high efficiency furnace (often PVC pipe used instead), the extra airflow in the chimney can become a major issue.

Chimney Condensation

The biggest concern for the chimney when changing the furnace efficiency is condensation. Specifically, acidic condensation droplets can build up in the chimney if not properly stopped. A new chimney liner must be placed in the chimney to avoid excessive corrosion due to the acid droplets. Keep in mind that the efficiency of your new furnace will determine whether you will use the traditional chimney for exhaust or if a new line will be installed to vent your furnace.

When to Take Action

If you have your furnace replaced, your technician will likely discuss the chimney situation in your home with you. Keep in mind that this might be necessary and that there might be an added cost involved because of it. Modern furnaces are not designed to accommodate aging chimneys and your safety and the integrity of your house are at risk if you don’t retrofit the chimney if necessary.

When Should You Replace Your Existing Heat Pump? A Guide from Latah

Monday, October 17th, 2011

Nobody wants to think about having to replace a home heating and cooling system in Latah. It’s a big job and a new system probably won’t come cheap – not if it’s worth buying anyway. But in the end, you’ll be better off replacing your heat pump sooner rather than later if you start noticing signs that it may be on its way out.

So what are these signs? Well, they’re actually pretty easy to recognize if you know what to look for. For instance, if your heat pump is suddenly making more noise than it used to, there’s a good chance that something’s going wrong inside. This may only require a minor repair, but if minor repairs like this become a regular occurrence, you should start seriously thinking about looking around for a new system.

The cost of even minor repairs will certainly add up quickly over time, and you’ll have to seriously think about whether it makes financial sense to continue to repair an older system rather than simply replacing it with a new one. Chances are that you’ll have to invest in a new one anyway, and the sooner you do it, the less you’ll have paid for repairs to a system you were just going to get rid of anyway.

Also, if you’re starting to notice humidity problems in your home or if some parts of your house are being kept warmer than others, it may very well be a sign that you heat pump isn’t working like it should. Again, this can sometimes be rectified with repair work, but especially if your heat pump is 10 years old or more, it probably makes more sense to replace it.

Another item to keep an eye on when you’re worried about how well your heat pump is working is your monthly energy bill. If you notice a sudden or even a gradual but steady increase over time that you know isn’t a result of an increase in energy prices in your area, you should suspect that your heat pump isn’t working like it should.

Even if it’s still keeping your home at a comfortable temperature, the fact that your heat pump is using more energy to do it is a sign that there’s something wrong with your system. Plus, newer systems are generally more energy efficient anyway, so you’ll be making up for the initial investment of purchasing a new system when you start paying even less on your monthly energy bills.

How Much Can I Save with New Equipment? A Tip From ACI Northwest

Monday, September 12th, 2011

There is certainly something to be said for upgrading your current Cheney home’s HVAC equipment to newer, more energy efficient equipment. Doing so can save you a ton of money in heating and cooling costs and it can make your home a more comfortable place in general. Of course, upgrading your equipment is a big investment, but ideally you will save enough on your monthly energy bills that it will more than make up for the initial cost of the installation.

But before you can decide whether or not it makes sense for you to upgrade, you need to know exactly how much you stand to save every month by upgrading. And that will vary considerably depending on several particulars of your situation.

For instance, you will have to take the age of your current system into account. No matter how energy efficient your system was when you first bought it, that energy efficiency has almost certainly deteriorated over time. Plus, the older your system is, the less energy efficient it probably was to start with. And the less energy efficient your current system is, the more you will save when you upgrade to a newer, more energy efficient system.

But that is not the only variable you will have to be on top of. The amount you will save monthly and annually will also have to do with how much you use your HVAC system. If you live in a rather temperate climate, you may use your HVAC much less, both in the summer and the winter.

In a case like this, the percentage you will save with an equipment upgrade will be the same as it would for someone who lived in an area with a harsher climate, but the actual dollar value will be much lower. All that really means is that it will take you longer to recoup your investment, but it may still be worth it to invest in a new system now.

You will also need to be aware of other factors that could impact the energy efficiency of your HVAC system. For instance, if your house is not well insulated, it will not matter how good your HVAC system is. You will still be paying more than you should to keep the indoors comfortable, and while investing in a new system may save you money, you will save more by taking care of your insulation problem first.

What Are Limit Switches and How Do They Work? A Pointer From Latah

Friday, August 19th, 2011

When you set the thermostat on your air conditioning system, you pretty take for granted that the system will maintain that temperature throughout your Latah home. But did you ever stop to think about how it’s actually accomplished? The truth is that there are many moving parts that all play a role in keeping your home cool and comfortable, and one of these is the limit switch.

What Is a Limit Switch?

Although you’re probably not aware of it, you’ve encountered plenty of limit switches over the years. A limit switch is anything that stops an electric appliance under certain circumstances. The little switch that turns the light on in the refrigerator when you open the door and then off again when you close it is the perfect example of a limit switch. Another common one is the switch that stops your washer or dryer from running when you open the door. Limit switches are used for a variety of appliances and gadgets to not only save electricity but to keep you and your device safe.

Limit Switches and Air Conditioning

The limit switch on your air conditioning system is the link between the blower on your air handler and the thermostat. When the thermostat senses that the desired indoor temperature has been reached, it stops the air conditioner from producing any more cold air. At that point, it’s important for the blower to stop functioning as well.

If it doesn’t, the blower will continue to move and warm air rather than cold will begin circulating throughout your home. However, if the blower shuts off too soon, the cold air that’s still being generated by the air conditioner won’t be able to circulate. So it’s essential that the blower be switched off at the same time the cold air stops arriving. That’s exactly what the limit switch does.

While it’s only one very small part of a large machine, the limit switch in your air conditioner plays a vital role in keeping your home comfortable and in allowing your air conditioning system to function as efficiently as possible.

If you notice that your air conditioner is shutting off too soon or not soon enough, it may be because of a broken limit switch. Sometimes, the system simply needs to be reset, something you can do with the help of your owner’s manual. However, if your limit switch is broken, you should contact a professional to take a look and determine if it needs to be replaced.
