Springfield HVAC Tip: Why Do Heat Pumps Need Refrigerant?

Monday, April 16th, 2012

Despite its name, your Springfield heat pump is not designed solely for heating. In fact, the technology in your heat pump was originally designed for air conditioning and is used today in air conditioners, refrigerators and cooling units in vehicles and airplanes. And the entire process relies on refrigerant – a chemical compound that is compressed and expanded to move energy from one environment to another.

 How Refrigerant Makes Heating and Cooling Possible

Springfield HVAC Your heat pump has quite a few components that work with the refrigerant to transfer it from one state to another. The compressor, as the name suggests, compresses the refrigerant to its liquid state. The liquid then runs through the expansion valve to the evaporator coils, where it expands into a gas. Refrigerant evaporates at a much lower temperature than water so it rapidly moves from one state to another, drawing heat from the surrounding environment.

That’s how an air conditioner or your refrigerator cool a space. However, in the case of a heat pump, the process can work in both directions. In cooling mode, your heat pump extracts heat from the air going into your home. In the case of heating mode, the heat pump extracts heat from the outside air. Because the heat is transferred into the refrigerant, it can then be recompressed by the compressor. The heat is then is then released in the condenser coils, where the gas returns to liquid state. A blower then distributes air blown across the condenser coils into your home as heat.

 Troubleshooting the Process

Your Springfield heat pump is a complex piece of machinery, but once you know how it works, you can perform quite a bit of troubleshooting should anything go wrong with the device. For example, if you notice cold air coming from your vents, you can check to make sure it isn’t in cooling mode and that there is enough refrigerant in the device.

Keep in mind that if any service needs to be performed on the heat pump involving refrigerant, you should call Cool It Heating & Air Conditioning due to the volatile nature of the chemical. In most municipalities, you must have a license to distribute or dispose of refrigerant and even if not, it can be dangerous to both you and the environment.

Common Heat Pump Performance Problems: A Troubleshooting Guide from Broomall

Wednesday, February 29th, 2012

The heat pump in your Broomall home needs to work year round to provide heat and air conditioning. This is why you want to make sure it’s performing as efficiently as possible to save on energy costs and prevent break downs. You should schedule an annual maintenance check-up and inspection with a certified HVAC technician to test the efficiency levels.

However, there are a few common causes of performance issues to be aware of so that you can be sure your heat pump performs at optimal levels. Call Cool It Heating & Air Conditioning if you have questions about heat pump performance issues, or to make an appointment for an annual inspection and professional cleaning.

Airflow Issues

There should always be a certain amount of airflow (measured in cubic feet per minute) in your heat pump to maintain proper efficiency levels. If the airflow is less than 350 cfm per ton, it could increase your energy costs. You should make sure your HVAC contractor checks the airflow whenever your heat pump is inspected. Always keep the coils clean. Sometimes the ducts are not the right size, or the fan speed needs to be increased, but often cleaning the coils will help airflow, which is why it is important to clean and maintain the components of your heat pump. A certified technician will know what methods are best, so if you suspect an airflow problem with your heat pump, call a professional heating technician.

Air Leaks in the Duct System

Inefficient or poorly-designed duct systems may not distribute air properly throughout your home because of potential air leaks. There should always be a balance between the intake and return air in a forced air system, which helps maintain a neutral pressure within the house and increase efficiency. Some contractors argue over how tightly a house should be sealed for this reason, but if your heat pump is losing heat through leaks in the air ducts, this will greatly affect its efficiency.

Improper Refrigerant

Refrigerant leaks are another common cause of low performance levels in heat pumps. Most heat pumps already have refrigerant when they leave the factory and shouldn’t have any issues. Heat pumps that are charged with refrigerant when they are installed can sometimes have the wrong amount of refrigerant. Either too much or too little refrigerant will lower the heat pump’s efficiency and performance levels. Always check the recommended refrigerant amount or ask an HVAC technician before you add refrigerant yourself.

If the heat pump in your Broomall home isn’t working properly, it is also affecting your heating bills. Call Cool It Heating & Air Conditioning today to set up an appointment.

Pros and Cons of Various Heating Systems in Glenolden

Monday, December 19th, 2011

When it comes time to install a new heating system in your Glenolden home, there are a lot of options to consider. Many people get overwhelmed when confronted with all of the furnaces, boilers and heat pumps on the market these days. So, to help you get a handle on what each has to offer and which will offer you the best benefits, here is an overview of the modern heating system market.

Furnaces

Furnaces are the core of a forced air heating system and use gas, oil or electricity to heat air which is then circulated through your home by a blower in your air handler. Furnaces are among the most fuel efficient heating systems on the market today with options available at up to 95% AFUE (meaning it uses up to 95% of the fuel consumed to produce heat). They are also inexpensive to install and while they don’t last quite as long as boilers, they are highly efficient when well cared for.

Boilers

Boilers use gas, oil or electricity to heat water or steam which is then circulated through your home into radiators or baseboard heaters. The heated water or steam releases heat into your home and heats it in turn. While not quite as energy efficient as a high efficiency furnace, boiler heat is perfect for homes with existing radiators and no room for vents and ductwork. It also has less of an impact on indoor air quality since there is no air movement and boilers tend to last a very long time when well maintained.

Heat Pumps

Heat pumps are becoming increasingly popular, especially in milder climates where it rarely gets below 40 degrees F. A heat pump uses the same technology as an air conditioner to extract heat from outside using a compressor, evaporator coils, and condenser coils with refrigerant.

It is most efficient in the spring and fall when temperatures are mild, but it uses much less energy than either a boiler or furnace and it can be used in the summer to cool your home. When properly maintained, a heat pump will last 10-20 years and save quite a bit of money, though it is recommended that you have an emergency heat source for days when the temperature outside gets below 40 degrees F.

How Often Should I Have My Geothermal System Checked? Some Pointers from Newtown Square

Wednesday, November 23rd, 2011

The beauty of having a geothermal system in your Newtown Square home is that is requires very little maintenance. They have fewer mechanical components are than other heating systems – and most of these components are underground or inside, shielded from the outdoor elements. The underground tubing usually is guaranteed to last 25-50 years and inside components are easily accessible for servicing.

Nonetheless, keeping a geothermal system working at peak efficiency is very important. If the geothermal system loses some of its efficiency, it will cost home and building owners money in energy costs, which makes little sense since geothermal system installation costs are higher than most other heating systems.

Its key component is the ground loop system, polyethelene tubing which carries refrigerant from below the Earth’s surface and back to an above-ground compressor. When installed correctly, the buried ground loop can last for decades. A leak in the metal tubing is usually the only problem if the ground loop is not installed correctly. In the case of a leak, it may be necessary to dig up the tubing – often installed at least ten feet below the surface – and repair the leak.

Other geothermal system components include its air handling unit, compressor, and pump. These components require periodic system checks by qualified professional heating and cooling technicians. Maintenance normally requires filter changes and component lubrication, to name the most common. In some cases, building owners can perform their own filter replacement and refill of lubricants. However, it is recommended that an experienced technician perform a multiple-point inspection of the geothermal system components, usually during regularly scheduled service calls.

What to Do About Cool Spots: A Tip From Boothwyn

Friday, August 19th, 2011

Sitting in your Boothwyn home on your couch watching TV should be an enjoyable experience, especially after a long day at the office. But, if your air conditioner deposits an abnormally high volume of cold air directly onto your couch, making you shiver despite the 90 degree heat outside, you may have a cool spot.

Cool spots are an unfortunate side effect of modern air conditioning technology. They occur when HVAC systems are improperly sized or ductwork is improperly installed. Other factors like insulation, vent configuration or window placement can also contribute to the presence of a cool spot (and possibly some hot spots). So, what can you do about it? There are a few options, starting with a quick inspection of the space.

Checking for Common Problems

Your inspector will check a number of things. Most importantly, they’ll measure the size of your HVAC system and compare it to the dimensions and particulars of your house. Usually, in the case of cool spots, the problem is directly related to an oversized system. When it turns on, even for a few minutes, it produces more cold air than is necessary, flooding your home with cooling. The thermostat recognizes this and the system shuts off soon after turning on. As a result, you’ll feel fluctuation between cold and warm as the system fails to properly condition the space.

Modern systems are sized for your house at 100% capacity. So, when the system turns on, it should stay on for a substantial period of time, keeping your home cool. Turning off and on frequently is bad for the system and wastes energy (plus it produces those pesky cool spots). Keep in mind that hot spots can also occur if the system isn’t powerful enough.

Your inspector will also look for vent placement and duct configuration. Improper placement of vents can lead to pooling of cool air that creates cool spots. By checking for potential problems in the layout of your HVAC system, an inspector can determine if new vents or ducts are needed to solve the problem.

Fixing the Cool Spots

For now, you may just want to move to another part of the house. Cool spots rarely affect the entire space – they tend to cluster around vents and outlets and can usually be fixed by resizing or adjusting your system. However, only your contractor can tell you for sure what the best solution will be for your air conditioning issues so make sure to schedule an inspection.

Why the SEER Is Important When Choosing an Air Conditioner in Newtown Square

Wednesday, August 3rd, 2011

There are many things to take into account when you are trying to pick out a new air conditioning system for your Newtown Square home. 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 about what system is right for you, contact your local air conditioning professional.

Home Repairs You Don’t Want to Ignore

Wednesday, June 29th, 2011

There are a lot of things you need to take care of around your home. But, everything costs money so many homeowners will put off certain home repairs for weeks, months or even years until they can afford them. However, there are certain things around the house you simply should not put off. Not only can they cost you more money in the long run, they can put your home and your family at risk if you wait too long.

Dirty Filters

Dirty filters in your air conditioning, heating, or air quality system are a problem. Not only do they force your HVAC system to work harder to maintain a good temperature, they are frequently a major cause of airborne contaminants and pathogens. Imagine it this way; those filters are meant to remove something from your air. If they get dirty and are not replaced or cleaned, they probably aren’t working any longer and you can get sick. Dirty filters are inexpensive and easy to fix. Both you and your HVAC repairperson should see to them regularly.

Dryer Vents

Clogged dryer vents are more than just an inconvenience – they are dangerous. If your home has dirty dryer vents, the exhaust from your dryer isn’t able to escape. When this happens, heat will build up in the ducts. Not only can exhaust backup into your home, the risk of a fire goes up significantly. Have your dryer vents cleaned at least once a year and if you live in a two or three family house, make sure it is more often – closer to every 6 months.

Flexible Gas Connectors

Gas connectors are used to transfer gas from the supply entering your home to various appliances like your stove, water heater and furnace. So, there is a lot of natural gas passing through them each day. If they are not properly cared for, that natural gas can start to leak from the connectors and eventually build up in your home to an unsafe level. You should have a carbon monoxide detector installed on every floor of your home and you should have someone come out and check your system regularly for problems.

Water Leaks

Water leaks are more than just messy – they can cause damage to fixtures and floorboards and over time can lead to the growth of mold and the weakening of your entire home. Especially in concrete or foundational walls, water leaks need to be seen to immediately. Even just a small leak can cost you money and put your home at an increased risk of damage.

Indoor Air Quality Options

Friday, June 24th, 2011

Maintaining high indoor air quality is always worth investing time and money in. After all, if the air inside your home isn’t healthy, it can cause all kinds of health problems for you and your family. The state of the art home heating and cooling systems we have today make it possible to enjoy a perfectly temperature controlled indoor environment all year long, but they also trap indoor air pollutants and contaminants inside without proper ventilation.

Choosing a System that Works

Luckily there are a number of great products out there designed to remove these pollutants before they cause you and your family discomfort or illness. Before you run out to buy a new system, however, you should first consider what each has to offer and what pollutants you need to remove. You might have some idea about this already, but the best thing to do is talk to a professional who can help assess your indoor air and determine which types of contaminants are most prevalent in your home.

Different types of indoor air cleaners are better at targeting different types of contaminants. For instance, HEPA filters can remove up to 99.97% of particulate contaminants that measure 0.3 microns or larger. This includes things like pollen, pet dander, dust mites and mold spores, so if these are the things you want to target, an indoor air system that uses HEPA filters is probably right for you.

However, if you’re more concerned with getting rid of smoke odors and cooking fumes, you probably want a system that targets even smaller particles. Air ionizers are more appropriate for these types of indoor air quality issues, as they can effectively remove much smaller particles than most HEPA filters. On the flip side, ionizers aren’t as efficient at removing the larger contaminant particles, so if you want to target both small and large contaminants, you need a system that combines both of these technologies.

Bacteria and viruses are also a problem when they find their way into your indoor air and they can be particularly tricky to get rid of. HEPA filters and air ionizers both have trouble completely eradicating these pathogens, but UV germicidal lights can be incorporated into your indoor air cleaning system to tackle biological contaminants effectively.

No matter what type of home air quality problem you have, there is a system on the market that will target and remove the pollutant. The key is to know which pollutants effect you the most and which products will do the best job of removing them from your home.

The Advantages of an Air Conditioning System

Monday, June 13th, 2011

Just about everyone knows that air conditioning systems keep your indoor environment cool and comfortable during the hot summer months. While this may be enough of a benefit for you, there are also some other benefits to having a central air conditioning system installed in your house as well.

For instance, if you have someone in your household who is more susceptible to extreme temperatures than most people, an air conditioning system can actually help improve their overall health. Babies certainly fall into this category, as they have more difficulty than older children or adults do controlling their body temperature.

Also, many elderly people or people suffering from certain medical conditions, particularly heart conditions, are especially sensitive to the heat. If they are unable to stay cool, it can be very dangerous and damaging to their health, and an air conditioning system helps to guarantee that they will be able to stay cool and comfortable even on the hottest days of the year.

Aside from direct health concerns, air conditioning systems can also help to alleviate the symptoms of colds and allergies. They do this by controlling the level of humidity inside your home. If the air in your house is too moist or too dry, it can exacerbate cold and allergy symptoms, as well as dry out skin and make the indoor environment generally uncomfortable.

Proper humidity control is also important because it helps to ensure that any air filtration or purification system you have in place is able to operate at peak efficiency. Many of these units have a hard time extracting particulate contaminants from the indoor air that circulates through them if that air is too humid or too dry. With a state of the art air conditioning system in place, however, you will not have to worry about whether or not the humidity level in your home is out of balance.

It is also worth noting that a central air conditioning system can be preferable to a window mounted unit because it provides for a more even distribution of cool air throughout the house. Also, when you have a central air conditioning system, the condenser which is the source of most of the noise and vibrations that air conditioners make will be located outside and out of earshot. With window mounted units, on the other hand, there is really no way to block out or diminish the noise.

What Is a Downflow vs. an Upflow Furnace?

Monday, April 4th, 2011

When you go looking to buy a furnace, you may well be surprised by how many different elements go into making a good purchasing decision. There are simply so many different kinds of furnaces available now and they each are more appropriate for certain situations. That means that finding the one that’s right for you is less about finding the one best unit than it is about finding the one that is the best match for your particular circumstances.

This applies to the type of fuel the furnace uses, its energy efficiency, and whether it’s an upflow furnace or a downflow furnace. Energy efficiency and fuel types are probably things that you’re more or less familiar with. But what are we talking about when we classify a furnace as an upflow or downflow model?

Well, it’s pretty much what it sounds like. These terms refer to the direction the air flows as it is taken in and heated by the furnace. So in an upflow furnace, the cool air is taken in at the bottom, warmed, and then expelled at the top. A downflow furnace, on the other hand, takes in cool air at the top and expels heated air at the bottom.

While this is all very exciting, it may still not be obvious what impact this will have on your decision about what type of furnace to buy. The main thing you’ll have to think about when you’re deciding between an upflow and a downflow furnace is where the furnace will be placed in your house.

An upflow furnace is generally installed in the basement so that the heated air is directed towards the parts of the house you want cooled and so that the furnace can be appropriately vented outside of the house. On the other hand, a downflow furnace would be installed in your attic for the same reasons.

So where you want to have the furnace installed is probably the biggest thing to take into account as you’re comparing these two types of equipment. Of course, whether you pick an upflow or a downflow furnace, you’ll still have to select the appropriate AFUE, size and fuel source to best meet your needs. But making the choice between upflow and downflow can at least make it easier to narrow down your options.
