Consider a Split Air Conditioning System When Replacing Your Old Unit

Friday, June 6th, 2014

Installing a new air conditioner can be a serious undertaking, and you should always consider all of the options before pulling the trigger on a replacement system. Here in Arlington, air conditioning replacement services can discuss all of your options with you, including the installation of an alternative system like a ductless mini-split system. Depending on the circumstances, you may wish to seriously consider a split air conditioning system when replacing your old unit. Here’s a brief discussion of the advantages of such a move.

As suggested by their title, ductless mini-split systems don’t rely on ducts spreading out from a central unit. Instead, they involve the installation of numerous individual units inside your home. Each one is designed to cool off a specific area (usually a single room). That allows you to tailor the temperature in each room as you wish, and to turn off the air in parts of the home you aren’t using. This is far more efficient than a centralized system, and can potentially save you a great deal of money on monthly bills.

The question becomes whether that savings is enough to offset the cost of installing a ductless mini-split unit, and possibly abandoning your existing duct system in the process. That could actually be a benefit if your duct system has run into problems. Installing a new ductless system may be easier and more cost-efficient than trying to repair extensive damage to an existing system, and the flexibility afforded by a ductless system can further sweeten the pot. You might also consider a ductless system if you have a particularly large house, only part of which you use in the day. The ductless system can help you save a great deal on monthly expenses over the years… perhaps even enough to offset the cost of installation.

We’re based in Arlington, air conditioning replacement is our specialty, and we can provide a whole range of options based on your particular circumstances.

What are the Advantages of Air Cleaners?

Friday, May 23rd, 2014

Air cleaners are essentially a more sophisticated form of air filters, using anything from UV light to electromagnetic static to help keep your air free of dust and dirt. They can usually be installed in your heater or air conditioning system with little trouble, and they bring a number of benefits to your household once they’re in place. Here in Arlington, air cleaners can be easily installed by a qualified air conditioning service company. What are the advantages of air cleaners? A few of the more common ones are listed below.

Advantages of Air Cleaners

  • Cleaner air. First and most importantly, air cleaners help improve the overall quality of your indoor air. Not only does that make your household more comfortable, but it can reduce the amount of allergic attacks in family members and help prevent other common forms of illness. You should especially consider this factor if you have an elderly member of your family, or you are expecting a baby anytime in the near future.
  • A more efficient air conditioner. When dust and dirt coat the inside of the air conditioner, it can increase friction on moving parts as well as interfering with the refrigerant’s ability to do its job. An air cleaner can help prevent dust from accruing, helping your air conditioner function more efficiently and lowering the cost of your monthly energy bills in the bargain.
  • Reduced need to dust. An air cleaner will reduce the amount of dust and dirt that builds up on your furnishings, which means that dusting and similar forms of housework will be made a lot easier.

The advantages of air cleaners are palpable, even for those without immediate health concerns. If you live in Arlington, air cleaners can also be used to help reduce the amount of bacteria and mold that crop up during our muggy summers. We can answer any question you might have, then install the air cleaner that’s right for your home and family.

Air Conditioning Basics: The Compressor

Friday, May 2nd, 2014

Understanding the basic components of a central air conditioner will help you know why you must schedule maintenance for your system every year. The refrigerant, the evaporator and condenser coils, the blower fan, the capacitors, and the motors are all essential parts of AC operation that must remain in good condition year-round in order for the system to work efficiently and effectively. But perhaps no other component in an air conditioner is as important as the compressor: it’s not only the heart of how an air conditioner runs, it’s the part that needs to stay in the best shape or else the whole system will fail. When a compressor dies, it often means the air conditioner must be replaced.

We’ll take a closer look at the compressor to see how it works—and how it might fail.

For the repairs and maintenance on your air conditioning in Arlington, VA that will keep the compressor healthy, call Polar Bear Air Conditioning & Heating Inc. today.

Compressor basics

The compressor isn’t the figurative heart of an AC. It’s the literal heart: it pumps refrigerant through the system in order to move heat from the indoors to the outdoors.

The compressor is a large pump that operates similar to a piston motor. It is located in the outdoor cabinet of a central air conditioner and only comes on when the thermostat calls for cooling. When that happens, the compressor (powered by its own motor) squeezes down on the liquid refrigerant inside it. This turns the refrigerant into a hot, high-pressure gas. The refrigerant exits the compressor to move to the nearest area of low pressure, the condenser coil. After the refrigerant completes its full trip through the air conditioner—releasing its heat to the outside, then absorbing heat from the inside—it returns to the compressor where the process begins again.

Like piston motors, compressors can wear down due to dirt and lack of lubrication. This will eventually cause the compressor to become “tight” and eventually “seized,” stopping all motion. Repair technicians can often repair the compressor to get its piston moving once more.

Eventually, an aging compressor will wear down to the point that it will burn-out completely: it will no longer be able to create the proper pressure for the refrigerant. This usually coincides with the end of the life service of the air conditioner itself.

Repairs and maintenance

Although a compressor will fail eventually, you can help it achieve the longest life possible with regular maintenance from a technician. Along with annual visits, make sure you call for repairs when you notice any odd behavior, such as the compressor failing to turn on, or stuttering at start-up and then turning off prematurely. A compressor that fails early in an air conditioner’s lifespan can mean the end of the system and the need to install a new one—the most expensive repair of all!

Since 2001, Polar Bear Air Conditioning & Heating Inc. has helped people stay cool through the summer with repairs for their air conditioning in Arlington, VA. Call us today to sign up for our maintenance program.

Is a Heat Pump Sufficient Year Round?

Friday, March 28th, 2014

Here in Arlington, VA, heat pumps are a viable alternative to forced-air furnaces and similar traditional forms of heating. They work as both a heater and an air conditioner year round, sending refrigerant gas through a series of coils that first heat the surrounding air and then cool it. In cooling mode, the heat pump asborbs heat from your home and transfers it outside, and in heating mode, it absorbs heat from the outside and transfers it into your home. They’re an effective and cost-friendly way to keep your home comfortable no matter what the season, but is a heat pump sufficient year round? Further south, they usually are. Here, however, they sometimes need a little help.

A heat pump’s big advantage is its efficiency. It doesn’t actually create heat or cold temperatures, it merely facilitates a heat exchange with the refrigerant running through its system. That means it uses much less energy than some other forms of heating and air conditioning, keeping your monthly costs down while providing an all-in-one option for conditioning the air in your home. There’s just one catch: that efficiency drops off considerably when temperatures approach freezing levels. Here in Virginia, we don’t get as many cold days as they do in, say, New England, but we certainly have our share of snow and ice in the winter, and a heat pump may not be sufficient during those periods.

The good news is that most heat pumps have electric resistance coils that kick on when the temperature outside gets too cold. They provide that extra bit of help the heat pump needs. You can also choose to combine your heat pump system with a back up furnace to use on very cold days.

If you’re wondering whether a heat pump is sufficient year round for your Arlington, VA home, and need some expert advice, then give us a call here at Polar Bear Air Conditioning & Heating Inc. We’re ready to help so don’t be afraid to contact us today!

Air Duct Problems and Furnace Repair

Sunday, March 2nd, 2014

Furnace repair is sometimes not a simple process. Your home contains numerous elements that can help or hinder proper heating, but a good technician can usually deal with any component in the process that isn’t functioning as it should.  Take for example, the duct system that carries heated air from your furnace to the various rooms of your house. Air duct problems and furnace repair go hand in hand: when issues crop up in your air ducts, they invariably affect the way your furnace functions.

Air ducts carry the heated air form your furnace, which means they can affect your air en route if there are problems. The most obvious is a breach in the duct system which allows the heated air to escape and/or cooler air to enter into the ducts. Both conditions have the same effect: lowering the temperature of the heated air and forcing your furnace to work harder to compensate.

Similar issues can arise if the ducts become dented or build-up inside them reduces the air flow. Furnaces depend on a regular flow of air to raise the temperature in your house. When a blockage in the ducts reduces the flow, the furnace must again work harder: raising monthly costs and increasing the chances of a more serious breakdown in the future.

In addition, the environment around the ducts can cause problems. Say, for example, that a stretch of ducts lies in the crawlspace next to an outside wall. The cold surrounding air will cool the sides of the ducts, which will in turn cool the air inside. You can alleviate this problem by adding more insulation to the crawlspace, or by insulating the ducts directly.

Reliable heating repair services like Polar Bear Air Conditioning & Heating Inc. can help with these issues. Call us today to set up an appointment!

Repair or Replace Your Existing Heating System

Tuesday, January 21st, 2014

Heating systems are designed to be run for many years, but sooner or later, you need to face the reality that a new system is necessary. You will have to decide whether you should repair or replace your existing heating system. It’s typically a case by case situation and you’ll need to decide for yourself it it’s worth it to repair a given system or simply install a new one. If you need any help with furnace repair in Arlington, VA, give Polar Bear Air Conditioning & Heating, Inc. a call.

That decision usually boils down to money, and how much you’ve spent on your existing heating system. If repair bills keep piling up and/or you’re dealing with a major cost to a given repair, you might prefer to consider a new system rather than sending good money after bad. Similarly, a furnace that has suffered from overall wear and tear might be due for a replacement, even if you don’t have any specific repairs. An inefficient heater with a lot of worn parts will use a lot more energy than it should to keep your home comfortable. As the months go by, those extra costs will add up until a newer, more efficient heater is really the only viable option.

Those issues can be compounded by the age of the system. In and of itself, an old heater doesn’t necessarily merit any replacement. If it’s functioning properly and you’ve kept it well maintained over the years, it can last well beyond its normal expiration date. On the other hand, if your heater is more than ten years old and you have to repair it a lot, or if it’s using more energy from month to month than it should, then its advanced age may be the final factor in deciding to install a new unit.

When asking whether to repair or replace your existing heating system, you can count on the experts at Polar Bear Air Conditioning & Heating, Inc. for advice. We handle furnace repair in Arlington, VA and we can help determine if your old unit is worth save or if a new one might be best. Give us a call to set up a consultation today. You’ll be glad that you did!

Paying Too Much for Heating in Arlington, VA?

Tuesday, October 22nd, 2013

In terms of heating, Arlington, VA homeowners need to watch the bottom line. Our winters can get cold, and a good heating system is often the only way to keep your home warm and comfortable when temperatures drop. A lot of people simply accept high heating bills as the price they pay for a cozy home. But it doesn’t have to be the case. Are you paying too much for heating in Arlington, VA? If you are, you can take steps to alleviate the condition.

It can be tricky to spot high heating bills, especially in the winter. Obviously, you are not going to use your heater as much during the fall as you do in the dead of winter. One good method to determine whether you’re using too much energy is to schedule a maintenance session for your heating device. A trained technician can arrive at your home and examine the heater for any signs of wear or use. If a small part is worn out, he or she can replace it. If dirt or dust have built up, he or she can clean the unit. If larger repairs need to be made, he or she can pinpoint the problem and schedule a later service date. Ideally, this maintenance session should take place at the end of cooling season, before the winter settles in. It allows you to spot potential trouble areas and increases the heater efficiency, helping to cut down on heating costs.

If you’re able to consider something more radical, look into the possibility of upgrading your unit to a newer and more efficient one. Heating systems have their efficiency measured in Annual Fuel Utilization Efficiency (AFUE) ratings, measured as a percentage. The higher the percentage, the more energy is spent actually heating the home instead of being wasted. Newer units have a higher AFUE rating than older ones, and this can lead to significant savings on your utility bills each month.

If you’re paying too much for heating in Arlington, VA, Polar Bear can help. Whether you want to install a new unit or just give a little care to your old one, our staff has the training and experience to do the job right. Call us today to set up an appointment.

Arlington, VA Air Conditioning Repair: Not Enough Cooling

Monday, September 23rd, 2013

The convenience of air conditioners is something we often take for granted. Their soothing white noise is part of the unnoticed backdrop of daily life. But you will notice if your air conditioner starts to lose its ability to lower the temperature. If the air from the vents in your home feels warmer than it once did, you might have an AC malfunction that requires repair. When you need work done on your air conditioning system in Arlington, VA, the right place to turn is Polar Bear. Our more than 10 years of experience means we are well equipped to care for home comfort systems.

Here are three common culprits that can impair your AC’s cooling ability and will require repairs:

  • Thermostat issues: The first step to take when you notice a weakening of cooling power in your AC is to inspect the thermostat to see that it is set correctly. A faulty thermostat can cause your air conditioner to turn off at the wrong times or to raise its temperature rather than lowering it. If simply changing the settings doesn’t help, then your thermostat will need repair or replacement.
  • Damaged ducts: If you have a standard air conditioner that relies on ductwork for air distribution, breaks and kinks in the ducts can lead to warmer air seeping inside. If a gap opens in a place where the air temperature is higher than the rest of your home (e.g. the attic or a crawlspace), your AC will draw in this warm air and blow it through the vents. Sealing the ducts with duct tape won’t solve this problem. It requires an expert using mastic sealant or other techniques to properly fix the damage.
  • Icing on the coils: Although you might think getting frost across the indoor coils would help with lowering the temperature, it seriously interferes with the important heat exchange across the evaporator coils and will mean less cool air. Icing often happens because of a leak in the refrigerant, although dirt on the coils can also trigger it. You will need an HVAC technician to diagnose the cause and make the repairs that will get the heat exchange back to normal.

Whatever your problem with getting proper cooling, trust the Polar Bear for reliable air conditioning repairs in Arlington, VA. Call us today to set up an appointment, and we’ll get the job done right the first time.

Air Conditioning Repair in Arlington, VA: Why You Need a Professional Technician

Monday, August 5th, 2013

It may be tempting to attempt air conditioning repair yourself instead of calling in a professional. This is especially true in Arlington, VA, where hot summers make waiting for a service technician uncomfortable and inconvenient. However, the prudent homeowner will always eschew do-it-yourself projects in favor of a skilled professional technician. The reasons for doing so may include, but are not limited to, the following:

  • Speed: Professionals know what to look for when an air conditioning unit malfunctions. They can usually spot the problem quickly and implement a solution with a strong understanding of the right steps. A person without any training may find themselves lost in the air conditioning system’s technical specifications, wasting time and energy without knowing what exactly needs to be done.
  • Accuracy: Without the experience and know-how of a professional technician, a do-it-yourselfer may exacerbate the problem instead of solving it. For example, if ice forms on the condenser coil and a layman simply attempts to get it off, he may end up damaging the coil without solving the original problem at all. A specialist can address the cause, not just the symptoms, and make sure the issue gets properly resolved.
  • Expertise: Many people undertake do-it-yourself projects as a way of saving money. But time and effort can add up, as can the cost of doing the job without the proper know-how. Certified professionals can ensure that the problem doesn’t recur. They can also provide routine maintenance service, helping you spot smaller problems before they turn into bigger ones. Not only does that save money in unnecessary repair costs, but it can extend the life of your air conditioning system.

Everyone wants to save money where they can. But when you weigh all the options, using a certified expert will spare you excessive costs and a lot of wasted time. If you need a professional technician for air conditioning repair in Arlington, VA, call Polar Bear Air Conditioning to set up an appointment. We pride ourselves on customer satisfaction, and are dedicated to doing the job right the first time, every time.

Arlington, VA Air Conditioning FAQ: Why Ducts Matter

Monday, July 15th, 2013

Your ductwork is not merely an add-on to your forced-air distribution system that keeps you cool all summer long. While often overlooked, your ductwork is a vital component, and necessary for your home comfort. There’s simply no substitute for ductwork that is professionally designed and installed according to the unique circumstances of your home. At Polar Bear, we understand the importance of ductwork, which is why we offer custom sheet metal services to our customers in need of professional air conditioning services in the greater Arlington, VA area.

  • Performance: Comfort during a Virginia summer comes down to the effectiveness of your air conditioning. In a central air system, your ducts are responsible for extracting the warm indoor air, sending it through the evaporator coils for cooling, and then returning it throughout your home. But they cannot provide the performance value you need if they are hampered by poor installation, air leaks, or poor connections.
  • Energy efficiency: Another important aspect of staying cool during the summer comes down to energy efficiency. When you installed your AC, it came with a SEER (Seasonal Energy Efficiency Ratio) rating as well as an estimated cooling output. Because these were meant to match your cooling and efficiency requirements, you need to make sure that your ductwork is also energy efficient, which means that it is not leaking air and that it is properly insulated. Professional ductwork installation can make all the difference, whether your home is 800 or 2000 square feet.
  • System lifespan: Another consideration is the lifespan of your entire system. Because of the vital role that ducts play in the every day operation of your AC, it’s no wonder that much of their wear and tear also impacts your ductwork. And vice-versa. In order to reduce the amount of wear and tear that your AC endures, it’s necessary that you keep your ducts clean and leak-free at all times.

Whether you need a comprehensive ductwork design and installation for your new home, or a simple repair, we can complete the job professionally so that you can get the most out of your air conditioning this summer in Arlington, VA. Call Polar Bear today.
