AC Problems You Need A Mounds View Air Conditioning Professional to Fix

Monday, August 6th, 2012

Doing the Basics

For small or big central air conditioning systems in Mounds View, regular cleanings and a filter change should be a part of every season. It’s not hard to remove the cover and replace the panel of webbing that catches lint and other particles out of your conditioned air.

Make sure the drain is clear, always cover the unit when more naturally cool temperatures take over and you’ve got conditioned air and relative peace of mind in the years ahead.

Big Problems

Without the regular service, however, an air conditioner begins to work much harder to produce the same amount (or less) of cool air and parts begin to break down.  With total neglect, the unit itself may need replacement much sooner than was promised when you paid for it. These are repairs that could be avoided and require a Mounds View air conditioning professional to make.

The key ingredient to cooling is a chemical called a refrigerant that is capable of transforming rapidly from gas to liquid and back again at low temperatures. This runs through two intricate tubes, a compressor, and a critical expansion valve that controls the process.  It is a delicate and complicated process that calls for expertise and the right tools, especially since the refrigerant is considered hazardous and requires special handling.

When the air gets stuffy, it could be that the fan is the problem.  Belts could be worn, loose or broken.  The motor may be low on oil and is stained to the breaking point.

If mysterious signs of water or mold are showing up on the inside of the house near the unit, there could be a problem with the condensate that is released with the heat when air is cooled.  This could be a simple or complicated fix, but should be checked out by a Mounds View AC contractor.

Linwood AC Question: Will My Air Conditioning Work Better with Dehumidification?

Monday, July 30th, 2012

There are a number of common misconceptions about humidity and air conditioning and how one affects the other. In truth, humidity is a major part of the discomfort we feel when the mercury rises. It can be 78 degrees outside but feel miserable simply because the humidity is high. So, many people in Linwood wonder whether a dehumidifier is a good solution to moderate heat and how it will work in tandem with an air conditioner.

Humidity and Your Air Conditioner

First, remember that air conditioning naturally lowers humidity because it cycles air through its condenser and evaporator coil. Conditioned air is naturally lower in humidity, regardless of what’s going on outside. So, if it is hot outside and humid, an air conditioner alone is very effective. On the other hand, a dehumidifier is useful is when the temperature isn’t that high but the humidity is.

Dehumidification not only lowers the relative humidity in your home, it reduces the need for cooling because you will feel more comfortable. Not only that, but a dehumidifier costs significantly less to run. So, when the temperature outside isn’t that high, there is no need to use thousands of watts per day of electricity just to stay comfortable.

This also reduces the overall wear on your air conditioner. Since it doesn’t need to run 24 hours a day to reduce humidity, wear and tear on the device is reduced and you save a tremendous amount of money on repairs and eventual replacement costs.

When to Use a Dehumidifier Alone

Generally, the Department of Energy recommends setting your air conditioner to 78 degrees and using a combination of a dehumidifier and fans to stay cool while it is off. If the temperature rises above that level, the air conditioner will turn on and supplement your dehumidifier. Consider too that a dehumidifier will reduce the burden placed on your air conditioner to pull humidity from the air. Humid air takes more energy to cool than dry air. Despite the fact that dehumidifiers will often raise the air temperature by 1-2 degrees, they save energy and make you more comfortable.

So, if you’re looking for a way to reduce your energy bill and enhance the longevity of your Linwood air conditioner, look no further than a quality dehumidifier. Call Air Mechanical Heating, Cooling & Plumbing today if you have any questions about installing a dehumidifier in your home!

Vadnais Heights Air Conditioning Tip: Breakdowns – How to Handle an Overloaded AC

Monday, July 16th, 2012

The last thing you need on a hot summer day is for your Vadnais Heights air conditioner to suddenly cut out. Without the cooling power it provides, your house will get uncomfortable quickly. Fortunately, once you know why this happens, there are several things you can do about it.

Why Air Conditioners Cut Out

The most common reason for air conditioner failure is an overabundance of pressure in the unit. This happens because the coil gets too hot, causing the pressure to rise in the entire device. As the pressure rises past a certain point, an automatic safety shutoff system is engaged. If you can stop the coil from heating up to this point, you can keep your Vadnais Heights air conditioner running.

How to Keep Them Running

Of course, this is easier said than done. Since your condenser unit with the coil inside is located outside in the heat, it’s only natural for it to get hot during the day – especially an extra hot day when you’re using your air conditioner a lot. You also need to be careful not to put anything over or up against your outdoor condenser unit.

While this may block the sunlight, it will also keep heat in the system and prevent the air conditioner from removing exhaust naturally. So in order to keep your air conditioner as cool as possible, make sure there is nothing up against the vents or impeding air flow in any way. Once you’ve done this, try and find a way to provide shade for you air conditioner without placing objects near the device. Blocking out direct sunlight is the best way to keep your air conditioner cool as long as you can do it without interfering with the system’s natural air flow.

Getting it Back On

If your unit does cut out on you, don’t despair. The best thing to do is to wait about a half hour to give your unit a chance to cool off on its own. Then, spray the coil and other overheated areas with a fine mist of cool water. This should lower the temperature enough that the system can come back on without any further complications.

If the problem persists despite the work you’ve done to keep it cool, you may want to call in a Vadnais Heights air conditioning professional like Air Mechanical Heating, Cooling & Plumbing to take a look and make sure nothing is broken or worn inside to cause the overloads. Most of the time a little maintenance will take care of the problem, but if not, you’ll want to get repairs done quickly to avoid a full breakdown.

Stillwater Air Conditioning Guide: The Ins and Outs of Ductless Splits Air Conditioning

Monday, July 2nd, 2012

So, it’s time to install a new air conditioner in your Stillwater home and you’re pretty sure there just isn’t enough room in the walls or ceilings to place the necessary ductwork. No problem. There is a rapidly evolving technology that allows you to have air conditioning without ductwork. It’s called mini-split ductless air conditioning and it relies on individual units placed in key locations around your house. Here’s how they work.

Multi-Zone Cooling

The first step is to install a central unit. This is your compressor and condenser and is usually placed outside like the core of a central AC system. These units range between 15,000 and 40,000 BTUs depending on how much cooling your home needs and will support up to 4 zones within your house.

Once the central unit is installed, smaller room-sized units are placed throughout your house. These units are designed for between 9,000 and 18,000 BTU spaces and are usually placed high on the wall of your room to distribute cooled air. The smaller units are connected to the main unit by refrigerant lines that are run up the side of your house (or inside if you want them out of the elements).

Because each indoor unit is individual and has its own thermostat, you save electricity by having direct control over each part of your home. In fact, the average ductless split system uses something like 30% less electricity than a standard air conditioning system.

Is it Right for You?

This is the most common question we hear and to be honest, it really depends on your needs. If you have a large house – we’re talking 3,000 square feet or bigger, a multi-zone ductless system may not provide enough cooling on its own. Most systems only support up to 4 individual units and therefore cannot cool massive spaces. However, if you have a smaller home, or more importantly have no space for ductwork, these systems are much more efficient than installing multiple window units.

How to Use AC Most Efficiently in Chisago City

Wednesday, September 7th, 2011

Air conditioning is definitely something most of us wouldn’t want to try and get through the summer in Chisago City without. And for a lot of people, because of medical or other conditions, it’s an absolute necessity. But just because you need to run your AC unit all summer doesn’t mean you need to suffer under the weight of cooling costs.

So if you’re interested in ways to save on cooling without sacrificing comfort, here are a few tips to get you started:

  • Get a Programmable Thermostat – When you come home at the end of a long day, you want your home to be cool and comfortable. But if you only have a basic thermostat, you would have to leave your air conditioning on all day in order to make this possible. Paying to cool an empty house is probably the last thing you want to do. But what is the alternative? Programmable thermostats offer the best solution in a case like this. These devices can be easily integrated into just about any home air conditioning system and they allow you to set different temperatures for different times of the day. That means you can have your air conditioning off while you’re not home and set it to come on a half hour or so before you get there. This way, you get the pleasure of walking into a cool, comfortable house without paying extra to keep it that way when you’re not home.
  • Incorporate Passive Cooling – The design of your home and how you use it can also have an effect on how hard your air conditioning system needs to work. Taking steps as simple as closing the blinds to block out the afternoon sun, putting up awnings and making sure that the exterior of your home is painted a lighter color to reflect sunlight rather than a darker one that will absorb it are all excellent ways to reduce the load on your air conditioner.
  • Supplement Your System – You can also take a good chunk out of your cooling bills by using things like ceiling fans in conjunction with your air conditioner. A ceiling fan can effectively lower the indoor temperature several degrees on its own, allowing you to set your thermostat a little higher.

Air conditioning is a major expense that most of us are resigned to paying, but there’s no reason to pay more than necessary with so many strategies available to save money.

What Is the Energy Star Label? A Question From Lino Lakes

Wednesday, August 31st, 2011

Any time you go out and buy any type of appliance in Lino Lakes, you probably notice that some have a distinct mark that signifies them as Energy Star appliances. That sounds like a good thing, of course, but what does it actually mean? Should you always buy an Energy Star model over another type?

The Energy Star label was originally developed to help consumers more easily recognize appliances that are more energy efficient than the average. In order to obtain an Energy Star seal of approval, any device must meet very strict guidelines when it comes to energy efficiency.

What that translates into for you as a consumer is a lower monthly energy bill when you buy Energy Star appliances. Of course, once they have obtained an Energy Star labels, manufacturers can charge whatever they want for their product, and it is not unusual to pay more for a model that is certified an Energy Star.

However, as long as the potential savings over time that you will get by using the Energy Star model as opposed to one that is not as energy efficient outweigh the difference in initial purchase price, it is worth it to spend a bit more on the Energy Star model.

Keep in mind, though, that just because a produce meets the Energy Star guidelines for energy efficiency does not necessarily mean that it is a superior product in terms of quality or overall effectiveness. Plus, not all Energy Star appliances are created equal. You should still do your research and pick out the product that will both save you the most money and has the best chance of getting the job done right.

Another benefit to Energy Star products is that, because they use less energy when they run, they also have a smaller impact on the environment than a model that uses a greater amount of energy to perform the same tasks.

Overall, it is definitely worth taking a closer look at all of the Energy Star options out there when you are purchasing an air conditioning system or any other type of appliance. Using less energy is always a good thing both for your bank account and for the planet. But you also want to make sure you are actually getting the best product for your money.

AC As a Safety Feature in the Home: A Pointer From Coon Rapids

Friday, August 26th, 2011

Ask a hundred people in Coon Rapids what the primary role of air conditioning is and I’ll bet you they say “comfort”. We seek out AC to stay cool and beat the summer heat, but did you know your air conditioning is a lot more than just a convenience – it is a safety feature in the midst of heavy heat waves.

Heat Is More than Just Uncomfortable

We tend to think of heat as this massive, uncomfortable inconvenience. In reality, it is quite dangerous. According to the Center for Disease Control, heat waves killed 8,015 people between 1979-2003, more than hurricanes, tornadoes, lightning, earthquakes and floods combined in that time period.

Why is heat illness so dangerous? It comes on quickly and it’s easy to ignore the warning signs, especially when you are already uncomfortable. While hydration is important, the real risk occurs after you’ve become dehydrated – when your body can no longer keep itself cool. This is known as heat stroke and can lead to a number of life threatening conditions, especially for the elderly, infants and those with chronic conditions.

That’s where air conditioning comes in. On the CDC’s extreme heat preparedness webpage, air conditioning is listed as the number one preventative factor against heat related illness. Simply put – if you have an air conditioner, there is a much smaller chance you will get sick from the heat. Dehydration happens less frequently when you’re in an air conditioned environment, meaning that your body can regulate temperature internally and you feel comfortable – not a bad deal for a simple installation.

Staying Cool Is a Medical Necessity

Heat is more than just a direct threat. It addles the mind and makes your reaction times slower. In effect, by allowing your body to overheat, you put yourself at risk. Simple tasks like climbing a ladder or taking out the trash could result in an injury because you don’t have the energy or the mental clarity to perform them as you would on a normal day.

So, air conditioning is about a lot more than just staying comfortable – it’s a health issue. Especially if you have small children or elderly adults in the house or if anyone in your family has a medical condition like obesity, heart disease, mental illness, poor circulation, an air conditioning system is an absolute must during heat waves.

Cleaning Air Conditioners: A Tip From White Bear Lake

Friday, August 19th, 2011

One of the best things you can do to help maintain high indoor air quality in your White Bear Lake 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.

Why Install a Ductless Air Conditioner? A Question From Wazata

Monday, August 15th, 2011

As you explore your options in terms of a new home air conditioning system in Wazata, 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.

How to Reduce the Load on Your Central Air Conditioner: A Tip From Fridley

Friday, August 12th, 2011

Your central air conditioner can handle a lot. It can keep your Fridley house cool and comfortable all summer long with only a minimum of maintenance. And if you have a newer, more energy efficient model, you probably are not even paying very much for this luxury. But no matter how good your air conditioning system is, it is always best if you can reduce its cooling load as much as possible.

Cutting down on the amount of work your central air conditioner has to do will save you money both in the short term and in the long term. You will be able to keep your house cool all summer while paying even less than you already do and you will help to extend the life of your system as well.

In general, reducing the cooling load that your air conditioner is responsible for involves keeping your house cooler by some other means. One great option when this is your goal is to have some ceiling fans installed. These help to circulate cool air and also create a breeze that can make it feel cooler even if the actual indoor temperature is the same.

With adequate ceiling fans in place, you will usually be able to turn up the thermostat on your central air conditioner and still be completely comfortable indoors. Turning up the temperature on the thermostat means that your air conditioning system will not have to work so hard because it will not have to get the indoor temperature down so low.

You can also reduce the indoor temperature in your house by blocking the sunlight that comes in and warms up the indoor air. Drawing the blinds, especially in those rooms that receive warmer afternoon sunlight will keep that sun from raising your indoor temperature. This, in turn, means that your air conditioning system will not have to work so hard to get the temperature back down.

You can also help to keep cool air inside and warmer air out by covering any doors and windows you are not likely to use with plastic. Also, check to make sure there are no cracks or drafts anywhere that may be letting in air from the outside or allowing cooler indoor air to escape. All of these things can make it possible for your air conditioner to keep your home cool without working so hard, and that will also mean that you will be paying less each month on your energy bills.
