What Is the Energy Efficiency Rating of Central Air Conditioners and Why Is it Important? A Question From Cobblestone

When you are shopping for a central air conditioning system in Cobblestone, 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. If you have more questions about which type of air conditioner will work for you, contact your local HVAC professional.

Air Conditioners and Humidity: Some Tips From Gladden Farms

Ever wonder why all of those air conditioners hanging out of people’s windows in Gladden Farms are constantly dripping water on hot summer days? All they’re actually doing is disposing of the moisture they’ve removed from the indoor air. That’s right – air conditioners are dehumidifiers too.

When you think about it, it makes a lot of sense. After all, you know how much more uncomfortable 90° is when the humidity’s up around 90% than when it’s closer to 60%. Of course, some air conditioners are better at removing moisture from the air than others, so you should definitely consider how well an air conditioner dehumidifies when evaluating your air conditioning options.

Why Humidity Matters

High humidity, even at lower temperatures is uncomfortable. But there are more reasons than simple comfort to want an air conditioner that reduces indoor humidity levels. For instance, high levels of humidity promote the growth and spread of several allergens like dust mites and mold spores. High indoor humidity can also cause problems for the wood fixtures and furnishings in your home.

The Importance of Proper Sizing

Most air conditioners do a decent job of controlling humidity indoors. But depending on the severity of your problem and the typical levels of humidity in your area during the summer months, you may want to pay special attention to each unit’s capabilities when evaluating your options.

An air conditioner’s ability to maintain proper humidity levels indoors has a lot to do with how well it’s matched to the size of your room as well. An air conditioner that’s too small likely won’t get the humidity or the temperature down to a comfortable level. On the other hand, that doesn’t necessarily mean that bigger is better.

In fact, an air conditioner that’s too large for the space you’re using it to cool will have a hard time bringing down the humidity level. Sure, you’ll wind up with a cold room, but that room will remain damp, making it no more comfortable than it was before the air conditioner was turned on.

For all of these reasons, it’s important to carefully evaluate your options when buying an air conditioner and make sure that the unit you buy is the right kind and size for the area you’re cooling. A little extra time spent researching your options will make your home infinitely more comfortable this summer.

Why You Cannot Neglect AC Maintenance: A Tip From Vail

If you have just purchased a new air conditioning system for your Vail home, maintenance is probably the last thing you are thinking about. In fact, if you are like most people, you do not think about your air conditioning system at all until it does not work when you need it. But if you simply continue to use your air conditioning system without maintaining it, you will be setting yourself up for a lot of problems later on.

Just like your car or any other machine that you run on a regular basis, your air conditioning system requires a regular tune up to keep it running like it is supposed to. The type of air conditioning system you have will dictate exactly how often this maintenance service needs to take place, but most systems benefit greatly from having a tune up once a year.

When you have just purchased an air conditioning system, the last thing you probably want to do is shell out a bunch of extra cash when the system is still running fine. But it really is much cheaper to pay now rather than waiting until you have a problem with your air conditioner to call for service.

During a regular maintenance visit, your technician will examine all of the component parts of your air conditioning system to make sure that they are working the way they should and not showing any signs of excess wear and tear. This is a great way to detect problems early, even when they have not yet begun to show in the air conditioner’s performance.

Your air conditioning technician will also thoroughly clean out your system to ensure that no excess debris is allowed to build up around the coil or other vital parts of the air conditioner. This is important because it helps the air conditioner to continue to function at peak energy efficiency levels. Without regular maintenance, your air conditioner will gradually lose efficiency over time. It will only lose a little bit every year, but if you do not do something to stop it, those little bits will quickly add up.

Regular maintenance also helps to prevent more costly and inconvenient repair visits later on. And it will certainly help to increase the lifespan of your air conditioner as well. Whether you have just purchased an air conditioning system or have had yours for several years, it is never too late to start your annual maintenance visits.

How Does Central AC Work? A Question From Safford

We pretty much just take the fact of central air conditioning for granted these days in Safford. It is present almost everywhere and it is hard to imagine getting through a long hot summer without it. But if you are like most people, you probably do not actually know how central air conditioning works. While you can certainly take advantage of it without understanding it, the basic concept is pretty simple.

Basically, central air conditioning systems are composed of an outdoor unit that typically houses the compressor and condenser and an indoor unit that manages the flow of air throughout your house or other building. This indoor unit is typically either an air handler or a furnace, and it directs the flow of air through a series of ducts that feed into the various rooms of the house.

The cool air originates in the outdoor unit and is blown into the house, gradually absorbing heat as it goes, and that air is then returned to the outdoor unit to be re-cooled. What actually happens in the outdoor unit involves the cycle of a type of refrigerant from a gas to a liquid and back. In the condenser area of the outdoor unit, the pressure on the refrigerant is lessened and it is able to absorb heat from the air returning from the house.

This gas, while warmer than the liquid refrigerant, is still quite cold and acts to cool the air being passed back into the house. As that refrigerant moves along to the compressor area, the gas is converted to a liquid and is forced to release the heat it had been holding. In that way, the air conditioner is able to remove heat from the inside of your house and release it outside.

Your air conditioning system is also generally hooked up to a thermostat, which is what controls when the unit switches on and off. You can set the thermostat at the temperature you would like to maintain inside your house and the thermostat will signal the air conditioner to switch on when the indoor temperature rises above that level. And once the indoor temperature is again below the preset level on the thermostat, the air conditioner will switch off again.

Why the SEER Is Important When Choosing an Air Conditioner? A Question From Oro Valley

There are many things to take into account when you are trying to pick out a new air conditioning system in Oro Valley. You want one that will be powerful enough to cool the required space but not so big that it turns your home into a walk in freezer. With so many models and types on the market, it can be difficult to figure out what details you need to pay attention to and what you can ignore.

The seasonal energy efficiency rating (SEER) that each air conditioner comes with is not something you should ever disregard, however. This number is a reflection of the overall energy efficiency of the unit and it can have a huge impact on the amount you pay to keep running your air conditioner every month. The higher the SEER of a product, the more energy efficient it is and the lower your monthly bills will be.

Of course, air conditioners with a higher SEER also generally come with a higher price tag, so you will have to weigh the amount of your potential savings against the difference in price of units with different SEERs.

To calculate this, you will need to know exactly how much more energy efficient one model is compared to the others. For instance, when you know that an air conditioner with a SEER of 11 is 7% more efficient than one with a SEER of 10, you are in a better position to evaluate the potential savings.

You will still need to translate this into dollars, of course, because the amount you save with a 7% boost in efficiency will depend largely on how much you typically pay already. If you are only paying around $320 a year with a SEER 10 air conditioner, upgrading to a SEER 11 will only save you about $30. However, if your annual cooling bills are closer to $1000, you will easily save close to $150 with this small upgrade.

SEER numbers go much higher than 10 and 11 too. In fact, the highest you will probably get is a 19.5 SEER, but that will more than cut your cooling bills in half if you are starting with a SEER 10. Still, the actual amount that you will save depends on how much you were paying to begin with, but if your cooling bills are already very high, it may be worth it to invest in an expensive but very high efficiency system. If you need more information, contact your local HVAC contractor.

Saving Energy with Air Conditioners: Some Pointers From Bisbee

Air conditioners can definitely make it easier to get through a particularly hot and sticky summer in Bisbee. But they are also pretty expensive to run, especially if you live in an area with long, hot summers. Fortunately, there are quite a few things you can do to help your air conditioner keep your home cool without running up those astronomical energy bills.

  • Think about Your Thermostat – Most people set their thermostat at one temperature and leave it there. But does it really make sense to pay to keep your home cool all day long when no one’s home? Instead, try turning up the temperature when you leave the house and then again at night before you go to bed. It’s likely you won’t notice the difference and even an adjustment of a couple of degrees can make a big difference.
  • Multiple Climate Zones – When you are home, of course, you want to set your thermostat to a temperature you’ll be comfortable with. But that probably still means you’ll be cooling a lot of empty space. Installing a multi-zone system allows you to set different temperatures for different parts of your home. You can keep the spaces you use regularly cool and comfortable without wasting money paying to cool the unoccupied parts of your home.
  • Ceiling Fans – It might seem silly at first glance to use a ceiling fan at the same time as an air conditioner. But the truth is that using a ceiling fan to compliment your air conditioning system can actually save you a lot of money. Ceiling fans use next to no electricity to operate and they can make the house feel a few degrees cooler. With that added help, you can turn your thermostat up a few degrees without sacrificing indoor comfort and save yourself quite a bit of money – more than enough to cover the cost of running the ceiling fan.
  • Keep Things Sealed – Making sure your house is well sealed and insulated is another important way to keep your energy usage down during the summer. The more cool air that escapes, the harder your system has to work and the more energy it will use.
  • Proper Maintenance – Keeping up with the recommended maintenance for your air conditioning system is the best way to make sure it maintains the highest possible level of energy efficiency. Over time, it will ensure your system stays efficient longer as well – well beyond the initial lifespan estimates.

What Are the Benefits of Having a Ceiling Fan? A Question From Cobblestone

There are definitely some days every year in Cobblestone that would be pretty miserable to get through without the benefit of a central air conditioning system in your home. And since you have a central air conditioning system in place, it may seem silly and unnecessary to think about having ceiling fans put in as well. There are actually quite a few benefits of having ceiling fans, however, regardless of what kind of central air conditioning system you have or how powerful it is.

Ceiling fans are not too expensive to put in and they take very little energy to run. But the breeze they produce can have a powerful cooling effect on a room. In fact, running a ceiling fan can make you feel up to eight degrees cooler than you would otherwise.

While this certainly is not enough on a really hot day, it can actually be plenty when the weather is not all that hot. But even if you have your central air conditioning turned on, you can still benefit from running your ceiling fan. That is because the cooling effect of the ceiling fan can allow you to turn up the thermostat for your air conditioner, resulting in a considerable savings on your cooling bill.

Because ceiling fans are so cheap to run, they can complement central air conditioning systems nicely and will provide significant savings over time. Running an air conditioning system alone can certainly keep you cool and comfortable all summer long, but it will also cost you considerably more than if you were to throw a ceiling fan into the mix as well.

And that is not all a ceiling fan can do to help you stay comfortable all year long. In fact, ceiling fans can also be of use in the winter because they help to return the warmer air to the lower parts of your rooms. Warmer air will naturally rise, meaning that your heating system will have to work harder and harder to keep the air in the lower part of your room warm. But with a ceiling fan in place, that warmer air will be re-circulated throughout the house to keep you warmer and help keep your energy bills down at the same time.

How to Stay Affordably Cool This Summer in Sahuarita

Putting in a high quality, energy efficient air conditioning system is a great step to take when you are trying to keep your house cool and comfortable all summer in Sahuarita without paying a fortune in cooling costs. Many of the latest air conditioners are able to use very little energy to provide powerful cooling power to your house no matter how big it is.

But if you are really serious about keeping cool and keeping costs down, there are plenty of other things you can do to give your air conditioning system a hand. It might seem silly, but putting in a little bit of effort around the house can save you quite a bit in the long run.

For instance, since you are paying to keep the air in your house cool, it is a good idea to make sure that the air you are cooling stays in your house. Sealing off unused doors and windows with plastic is an excellent precaution to take to ensure that no cooled air leaks out through the cracks and door jambs. Also, you will want to check for any other openings that could create a draft and allow cool air to escape or warm air to get in.

However, just letting in air from outside in the summer is not the only way that the heat can get in. The sun is powerful in the summer and the more you can block of it, the cooler your house will be. So make sure that your blinds are closed to block out the sun, particularly in the afternoon. Morning sun is not nearly as powerful as the sun you get towards the middle and later part of the day.

All of these steps will help to take the pressure off of your air conditioning system and allow it to get its job done with a minimum of energy expended. And that will certainly save you money every month. You can save even more, though, by adjusting the temperature on your thermostat a bit as well.

Most air conditioning systems are set to a default temperature of 72°F. While this is probably quite comfortable for you, it is likely that you would be equally as comfortable at 75°F. In fact, you probably will not even notice the difference. But that small adjustment on your thermostat can actually save you quite a bit on your monthly cooling bills.

Cleaning Air Conditioners in Cortaro

One of the best things you can do to help maintain high indoor air quality in your Cortaro home is to clean your air conditioning system on a regular basis. While these systems make it possible to endured a long, hot summer with minimal discomfort, they can also become a breeding ground for bacteria, mold and other indoor air contaminants that can make you sick or cause other types of problems.

Improving your indoor air quality isn’t the only reason you should worry about keeping your air conditioning system clean. A properly maintained air conditioner will function more efficiently for a longer period of time.

Air Filters

Changing or cleaning out your air filters regularly is one of the easiest and most important parts of air conditioner maintenance. These air filters are your number one line of defense against all manner of indoor air pollutants, but if they become saturated, they can no longer do their job. Fortunately, changing out these filters is a quick and easy job. Just mark the date on your calendar so you don’t forget.

Ducts

Without the system of air ducts that run through your home, your air conditioner wouldn’t be able to circulate all that cool air. But they’re also a very attractive place for dust, pollen, mold and other indoor air contaminants to collect. Unfortunately, the majority of your ductwork occupies space behind walls, beneath floors and in other equally inaccessible areas of your home.

For that reason, it’s generally necessary to have a professional with specialized equipment come out and clean your ducts once a year. By keeping up with maintenance, you can be sure that your air ducts aren’t harboring dangerous contaminants that your air conditioning system can then spread throughout your home.

Cooling Coils

The cooling coil is another part of your air conditioning system that needs to be cleaned on a regular basis. If your cooling coil is dirty, it won’t actually affect your indoor air quality, but it will impede your air conditioner’s ability to function effectively. The more sediment and debris allowed to build up on your air conditioner’s cooling coil, the less efficiently it will cool the air that passes over it. And if it can’t cool the air properly, your air conditioner will have to work overtime to maintain a comfortable temperature inside your home.

Ductless vs. Duct Air Conditioning Systems: A Tip From Tubac

When it comes time to pick out a new air conditioning system for your home in Tubac, you will have to make the choice between ductless and duct models. While both of these types of systems have their advantages, the specifics of your situation will go a long way to determining which one is right for you.

Ductless air conditioning systems are becoming more and more popular these days for a number of reasons. For one, they are generally considered more energy efficient than their ducted counterparts. Also, ductless systems are often cheaper and simpler to install, particularly in a house that does not already contain ductwork.

These types of air conditioners use refrigerant lines to connect the indoor unit or units to the outdoor compressor. The refrigerant lines take up much less space than ducts do and they also are much easier to install. Refrigerant lines can also reach into areas of your house that ducts may not be able to, making it possible for you to bring the benefits of air conditioning to places that did not have access to it before.

The indoor unit of a ductless air conditioning system can generally handle the cooling load of one or two rooms, but if you want to cool a larger space, it will be necessary to install multiple indoor units throughout the house. All of these units can connect to the same outdoor compressor and they can also be controlled individually. That means that you can set different temperatures in different parts of your house and you do not have to pay to cool the entire space if no one is occupying certain parts at the moment.

A duct air conditioning system also involves indoor and outdoor components. However, these elements are connected to each other by a system of ducts rather than by refrigerant lines. In a duct system, cooled air is brought inside from the compressor and then circulated through various ducts by the air handler.

The latest duct systems are quite energy efficient as well, and they can also be coupled with zone control systems to create different climate zones within your house. Particularly if you already have some ducts in place, a duct air conditioning system can be a great option for you.
