There are so many different types and styles of air conditioners on the market these days, it can be difficult to figure out what features are worth paying attention to when it comes time to buy one for yourself. One helpful way to simplify the process is to consider a few tips for choosing an air conditioner based on your specific home and cooling needs. Air conditioning is not a luxury but a necessity during high temperatures, especially in regions like Allentown, where reliable cooling is essential for comfort.

Of course, the most important thing to do is make sure you get an air conditioner that’s appropriately sized for the space you’re trying to cool. But what should you look for beyond that? For instance, if your current unit is underperforming or frequently breaking down, it may be worth recognizing the signs your AC should be replaced before investing in new features. Here are a few features you might like to have on the unit you purchase:

  • Energy Efficiency – The more energy efficient your air conditioner is, the less your cooling costs will be. It’s as simple as that. So when you’re evaluating devices, remember that it’s worth paying a little bit more up front for a more energy efficient unit. It will save you money in the long run and you’ll be doing your part to help the environment. You might also want to explore potential air conditioner upgrades to consider that enhance efficiency and overall comfort. Many reputable brands, such as Carrier, Trane, Lennox, and Rheem, offer models with high efficiency ratings.
  • Dehumidification – Just about every air conditioner controls humidity to a certain extent in addition to cooling. But some do this better than others. There are also air conditioners with separate dehumidification settings for those days that are more humid than hot. Even when you need both cooling and dehumidification, it’s nice to have control of each of these independently.
  • Timer – Being able to program your air conditioner to switch on and off at different times of day is more than just convenient; it will save you money. You don’t want to leave your air conditioner running all day when you’re not home, but it sure is nice to come home to the comfort of an air conditioned space. If your air conditioner has a timer, you can have both. Just set the unit to come on a half hour or so before you get home and you’ll enjoy cool, refreshing indoor comfort right when you get home without paying through the nose to keep your home cool when no one is there.
  • Easy-to-Use Controls – As simple as this one seems, you might be surprised at how inconvenient the controls on some air conditioners can be. So when you’re evaluating your options, make sure you research how easy each unit is to operate. This can definitely save you from plenty of frustration in the long run.
  • Warranties and Service – When comparing models, check for strong warranties and reliable service to ensure peace of mind and long-term support.

Air conditioners come in many different shapes and sizes. To make sure your decision works best in your home, do your research well in advance. When the summer heat kicks in, you’ll be glad you did. Don’t wait until your system is completely non-functional before considering a replacement—timely action can help you avoid discomfort and costly repairs.

When researching your options, begin by searching for honest, family-owned AC service providers in Allentown who take pride in their job and have a skilled team. Start by searching for local providers and reading reviews to know what to expect from the installation process. Choosing the right model and having it installed by a reputable team ensures long-term value and satisfaction.

Professional installation is crucial for optimal performance. Installing an air conditioning unit can be dangerous without the right tools and expertise, so it’s best to contact or speak with a professional to ensure the job is done right. Many AC companies also offer heating and plumbing services, making them a one-stop shop for comprehensive home maintenance.

Air Conditioner Components and Potential Issues

A reliable air conditioning system is made up of several essential components, each working together to keep your home cool and comfortable. The compressor, condenser coils, evaporator coils, refrigerant, and thermostat all play vital roles in the performance of your air conditioning unit. When any of these parts experience problems, it can impact the efficiency and effectiveness of your entire cooling system.

One of the most common issues homeowners face is a refrigerant leak. When refrigerant levels drop, your air conditioning unit may struggle to produce cool air, leading to higher energy bills and less comfort. Skilled technicians from a reputable ac company can quickly diagnose and perform air conditioning repair to resolve refrigerant leaks and restore your system’s performance. Another frequent problem is a malfunctioning thermostat, which can cause your ac unit to cycle on and off at the wrong times or fail to maintain the desired temperature. Prompt air conditioning repair services are essential to prevent further damage and keep your home cool, especially during the hottest days of the year.

Regular maintenance is key to preventing these issues and extending the life of your air conditioning system. Air conditioning maintenance services, such as cleaning or replacing the air filter and checking the coils, help ensure that your system runs efficiently and doesn’t blow warm air when you need cooling most. PA homeowners can rely on trusted air conditioning services to provide thorough inspections, tune-ups, and repairs, saving money on energy costs and avoiding unexpected breakdowns.

If your current ac unit is outdated or frequently in need of repair, it may be time to consider a replacement. Investing in a new, energy-efficient air conditioning unit can improve your home’s comfort, reduce energy consumption, and increase property value. When selecting a new system, factors like the size of your house, your budget, and the type of cooling system you need should all be considered. An experienced ac company can guide you through the process, ensuring you choose the right unit for your needs and handle the installation with care.

No matter the issue—whether it’s a refrigerant leak, malfunctioning thermostat, or simply the need for regular maintenance—having access to professional air conditioning repair and maintenance services is a necessity for PA homeowners. By relying on skilled technicians and investing in regular maintenance, you can keep your air conditioning system running efficiently, protect your investment, and enjoy a cool, comfortable home all summer long.

The evaporator coil is an essential piece of your air conditioning system. It absorbs heat from air that passes over it, and that air then travels into your home to cool it. So if your coil is dirty or isn’t functioning properly, the cooling power of your air conditioning system is diminished. Fortunately, this problem is fixed easily by cleaning the evaporator coil. You can do this on your own or have a professional come in to take care of it.

Signs of a Dirty Evaporator Coil

The most obvious sign of a dirty evaporator coil is an overall drop in system pressure. As long as you know what constitutes a normal pressure for your system, you should be able to tell if the current pressure is below that level. If it is, a dirty evaporator coil is probably your culprit. You can also check the static pressure in your system to see if that is low, but this requires specialized equipment.

Even if you don’t notice any particular signs that your air conditioning system isn’t working properly, it’s a good idea to clean your evaporator coils once a year or so. This can help prevent any larger problems from developing in the future.

Finding Your Coil

Probably the hardest part of cleaning an evaporator coil is reaching it. Unlike your condenser coil, which is located in your outdoor condenser unit, the evaporator coil is found inside near the air handler or furnace. If you have the owner’s manual, there should be detailed instructions telling you where the coil is and how to safely access it.

Alternately, you can have an HVAC technician show you what to do the next time they come out to work on your system. Whatever you do, though, make sure that power to your AC unit is completely shut off before you start working on it. Once you’ve gained access to the coil, use a brush or vacuum attachment to remove any debris or sediment you find there.

The Importance of Maintenance

Cleaning your evaporator coil is only one part of the regular maintenance required to keep your air conditioning system in good working order for the foreseeable future. There are plenty of things you can do on your own, but it pays to have a professional come out once a year or so to check out the entire system and make any necessary repairs.

When you set the thermostat on your air conditioning system, you pretty take for granted that the system will maintain that temperature throughout your house. 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.

If you’re like most people, you probably don’t think too much about how your air conditioning system works. All you really need to know is that when you switch on the system, your house gets cooler. But if you’re looking to purchase a new air conditioner for your home, it’s a good idea to know how to select the right one to fit the space you’re trying to cool.

Air Conditioning Basics

Air conditioners use Freon as a coolant to remove heat from indoor air and transfer that heat outside. To do this, they cycle the Freon through a closed loop of coils. When the cold Freon enters the cooling coil of the air conditioner, it absorbs heat from the air passing by, thereby lowering the temperature of the air. That cooled air can then be transferred into your home and more warm air can be cycled past the cooling coils.

Air Conditioner Sizing

The more air your air conditioner can cool at once, the larger its load capacity. In order to keep a particular space cool, an AC unit has to have a large enough load capacity to accommodate that type of air volume. A unit that’s too small will obviously never be able to keep your room cool enough, but one that’s too big will have a similar problem.

The truth is that when it comes to air conditioner sizing, bigger is not better. It’s best to simply get as good an estimate as you can of what type of load capacity is ideal for the space you’re trying to cool and stick as close to that as you can.

Load Capacity and Freon

Of course, if you want your air conditioner to cool more air at a time, you’ll need more coolant. But simply increasing the amount of Freon in your air conditioner won’t make it cool any better. Freon is simply one of many elements that contribute to effective cooling. And the larger the entire system is, the more Freon is needed.

So more Freon technically contributes to greater cooling capacity, but it’s not enough to accomplish that all on its own. There is really nothing you can do to increase the load capacity of your air conditioner once it’s in place. So for best results, make sure you pick out an appropriately sized unit the first time around.

If you’ve been looking at air conditioners, you’ve probably noticed that they all seem to have a SEER rating. But what does this actually mean?

The SEER, which stands for Seasonal Energy Efficiency Ratio, is a measure of how energy efficient a particular air conditioning model is. So when you’re shopping around for the best deal on an air conditioner for your home, this is something you’ll absolutely want to pay attention to.

Interpreting SEER Ratings

The SEER rating system is relatively simple – the higher the SEER, the more energy efficient the product. But because a higher price tag typically comes with a higher SEER rating, it’s important to know just how much more efficient a higher rated unit will be. It helps you decide whether paying significantly more for a higher rated unit is worth it in long term savings. Will it actually save you enough each month to make up for the difference in price?

Evaluating Your Energy Usage

A big factor here is how much you will use your air conditioner. If you live in a place with very hot and humid summers where the air conditioning runs constantly, you’re probably best off with the highest SEER you can find. When you consume that much energy to keep your home cool, you want to get as much as possible out of it, and that’s what a high SEER model can do for you.

On the other hand, if you live in an area that doesn’t have the harshest summers, you may be better off with a slightly less efficient (and therefore cheaper) model. Keep in mind, too, that the actual percentage increase in energy efficiency goes up by smaller and smaller increments the higher in SEER ratings you get. For instance, while a 10 SEER unit may be almost 20% more efficient than an 8 SEER model, a 12 SEER is only about 10% more efficient than that 10 SEER.

Finding the Right Balance

The best way to decide what SEER rating is best for you is to determine the annual cooling costs with your current unit and then calculate your savings in dollars based on the percentage each model would improve your efficiency. If you don’t currently have an air conditioner, this can be a bit tricky, but a professional contractor or air conditioning salesman can help you estimate your total monthly cooling costs with the various units.

You’ve probably heard many arguments for why you should purchase an energy efficient air conditioner. They may cost a bit more up front, but they’ll save you money in the long run by cutting down on your monthly energy bills. They’re also better for the environment because their lower energy usage means less fossil fuels are burned to keep them running.

But there’s another reason energy efficient AC units are better buys than your standard alternative. There are Federal tax credits available to consumers who purchase them. This tax credit can more than make up for the higher purchase price of the units, allowing you to enjoy your monthly savings much sooner and know you’re doing your part to protect the environment.

How to Qualify

In order to qualify for 2011 air conditioning Federal tax credit, you need to purchase an appropriate energy efficient AC system. Your HVAC contractor or salesperson can tell you which models and units qualify for this program. Just make sure you save all documentation and proof of purchase in case you need them to validate your claim.

The AC units that qualify you for this tax credit include those with a SEER (seasonal energy efficiency ratio) of 16 or greater and an EER (energy efficiency ratio) of at least 13. These two numbers are the best and clearest indicators of the overall energy efficiency of the product and can easily be found on the packaging for any air conditioning unit. While a 16 SEER is very good, it is not the highest rating currently available, either, so you won’t be forced to buy the most expensive model available to get your credit.

Credit Details

The tax credit is good for up to 10% of the purchase price of the unit up to $300. Keep in mind, though, that you can only claim up to $500 lifetime towards this program. So if you’ve previously claimed $250, you can only claim an additional $250 for 2011. That’s still a significant savings, though, and well worth looking into if you’re in the market for a new AC unit or system.

So if you’ve been thinking about upgrading your AC system, but haven’t quiet gotten around to, now may be the time to take advantage of this great tax credit opportunity before it’s too late.

Just about everyone can agree that effective ventilation is essential to maintaining a healthy indoor living environment. But exactly what does this entail? There are quite a few ways to circulate air throughout your home, and each method is appropriate for a specific situation.

Benefits of Natural Ventilation

Natural ventilation, of course, can be achieved simply by opening a window. But there’s actually a lot more to it than that. If you really want to ventilate your home through natural means, then you’ll have to learn to take advantage of the differences in pressure in different areas of your home.

One way to do this is to use cross ventilation. This means opening windows or doors on both sides of your home and allowing the outdoor air to blow through, carrying stale, indoor air out the other side. A more sophisticated version of this is stack ventilation.

In a two-story home, stack ventilation can be achieved by opening the windows on the bottom floor on one side of the house and on the top floor on the opposite side. Because of the differences in outdoor air pressure, air will be sucked in through the lower floor windows and out through the upper ones.

Why Natural Ventilation Is Not Always Practical

These types of natural ventilation can be extremely effective when it comes to both cooling an indoor environment and removing indoor air contaminants. Unfortunately, allowing outdoor air inside unimpeded allows outdoor contaminants easily as well.

On particularly hot or humid days, natural ventilation can’t reduce the indoor temperature enough to make it comfortable indoors. While a light breeze is enough to take the edge off on a moderate spring or summer day, more is needed when the weather is extreme.

Types of Mechanical Ventilation

When you think of mechanical ventilation, you probably jump right to large central air conditioning systems. But that’s certainly not the only type of effective mechanical ventilation available. In fact, mechanical ventilation can be performed by just about any type of fan on the market, and while operating a fan is certainly more expensive than opening a window, it’s still much more affordable than running an air conditioner all day long. Fans can also be used in combination with natural ventilation to achieve better results than either system could on its own.

As you explore your options in terms of a new home air conditioning system, you will probably have to decide whether you want a system that uses ducts to get the cooled air around the house or one that is considered ductless. Each type of air conditioning system is appropriate in certain situations, so it is important to understand the benefits of each before you can make a decision.

Duct air conditioning systems are the more traditional type on the market today. They generally consist of an outdoor compressor and condenser unit and an indoor air handler. The outdoor unit passes the cooled air through ducts to the air handler, which then takes over circulating the air through the house and back out to the condenser again.

It makes sense to install this type of air conditioning system if you have a large house or if you have ducts already in place. Duct air conditioners can cool a moderate to large sized house quite effectively and they can also be coupled with zone control systems to give you multiple climate zones within your house.

Ductless air conditioners, as their name suggests, do not rely on a system of air ducts to get cooled air distributed throughout your house. Instead, these types of systems use refrigerant lines to transfer coolant from the outdoor compressor to the indoor, wall mounted units. Each of these indoor units can take care of cooling one or two rooms, but in order to cool an entire house with one of these systems, you will need to install multiple indoor units.

However, these multiple indoor units can all be connected to the same outdoor compressor, and they can also be controlled independently. That gives you much greater control over which parts of your house are cooled and how much energy you are using to cool areas that may or may not be occupied.

Ductless air conditioners are generally more energy efficient than ducted ones, but their real advantage comes from the facts that they can be installed even in places where air ducts do not exist or cannot go. If you do not already have ductwork in your house, installing a duct system will add considerably to the price of installing a ducted air conditioning system. In a case like this, a ductless system is much easier and cheaper to install and certainly makes more sense.

When you are in the market for a new air conditioner, one of the decisions you will have to make is whether you want a two stage system or one that only functions in a single stage. Of course, before you can make a decision about this, you need to know what all of this means.

A single stage air conditioning system is probably what you are most familiar with. They have been around for longer and can be found in a wide variety of locations. Single stage air conditioners come on at full capacity when the temperature in your home rises above the preset level on the thermostat. Once they have effectively cooled the house, these types of air conditioners shut off until the temperature works its way back up again.

Two stage air conditioners, on the other hand, can function at either 67% or 100% of capacity depending on exactly how warm it is in your home. What that really means is that if the temperature in your home is only a little above the thermostat’s preset limit, the air conditioning system will come on at 67% and gradually cool the house to keep it right in a comfortable range.

However, if you have not been home for a while and your home has gotten very warm inside, your air conditioner will come on at full power to get the temperature down quickly. What this really means is that your air conditioner will be running more than a single stage air conditioner because it will sometimes not be using all of its power to cool.

The end result of using a two stage air conditioner is that you will receive a relatively continuous flow of cool air throughout your home. A two stage air conditioner will send in a steady but smaller stream of cooled air as opposed to the large blast of cold air you would get from a single stage system.

This results in a more consistent and comfortable environment overall, and it also makes it possible for the air conditioning system to dehumidify your house more effectively. When the air is cooled too quickly, the dehumidification system does not always have time to do its job. But with the longer cooling cycles of the two stage system, there is plenty of time to make sure the right amount of humidity is removed from the air.

If you already have a central air conditioning unit, you probably have not though much about having some ceiling fans put in as well. After all, why would you need a fan when your air conditioner can keep you as cool as you want all year long?

Well, the truth is that a ceiling fan can actually contribute a lot to your household even when you do already have the central air in place. It can also save you quite a bit of money when it comes to your monthly cooling costs, so there is really no reason not to look into getting a ceiling fan of your own.

Certainly the air that air conditioners distribute throughout your house is quite cool. But a ceiling fan will help to circulate it much more effectively. In fact, a good ceiling fan can make a room feel up to eight degrees cooler than it actually is just because of the cooling affect that moving air has on your body.

This means that you could set the thermostat on your air conditioner higher and still enjoy the same level of comfort that you are used to. You may already know that for every degree you raise your thermostat in the summer you will be saving up to 3% off of your regular energy bill. So if you can turn the air conditioning down by more than five degrees, you will surely be seeing some substantial savings.

Of course, you are still running the ceiling fan in place of the air conditioner, but the fan will use only a very small fraction of the energy that the air conditioner does. This all means that having a ceiling fan and using it wisely can help you cut your annual cooling costs dramatically.

And a ceiling fan will be useful in the winter as well. Since heat rises, you can turn your fan on backwards and it will push the heat that has risen to the top of your room back out along the walls and down. This means that you will be getting more for the heat you are paying for as well, making the ceiling fan a great money saver all year long.
