Alexandria, VA Air Conditioning Repair Question: Why is My AC Blowing Warm Air?

Thursday, August 1st, 2013

It doesn’t take an expert to figure out that something’s wrong when your AC blows warm air. An air conditioning unit is supposed to cool your house, not warm it. In Alexandria, VA, air conditioning repair is no laughing matter; no one wants hot air blowing into their homes in the middle of a Virginia summer heat wave. But why would an AC blow hot air in the first place? Why is it that the fan seems to work fine, but the cooling process is ineffective?

In some cases, the explanation may be very simple. Your thermostat may have been set to a “fan” or “heat” setting, which blows plenty of air around, but doesn’t cool it (check on this before you contact a service professional). Another common – and more serious – cause of warm air flow is a low level of refrigerant in your air conditioning system. Without enough refrigerant, the air won’t be cooled properly, and a leak in refrigerant lines means that a service technician will need to hunt down the source of the leak and recharge the system.

Similarly, if the air conditioning system isn’t properly maintained, then dust may build up on key components like the condenser coils or evaporator coils. That can impact the system’s ability to cool the air. You may also be facing a dirty air filter or damaged ducts, which impede the overall flow of air and may affect the flow of cool air into your home.

Unless the thermostat has been set incorrectly, all of these issues mean opening up the air conditioning system and checking for problems, a task best performed by a professional.When your AC starts blowing warm air, call the experts at Polar Bear Air Conditioning. Contact us today and set up a service call; we’ll be there to do the job right, and are committed to your 100% satisfaction.

Signs You Need to Schedule Air Conditioning Repair: An Alexandria, VA AC Tip

Tuesday, July 23rd, 2013

Homeowners expect their air conditioning system to function effectively, and in Alexandria, VA, they need a reliable system to help combat those humid summers. When something goes wrong, a prudent homeowner needs to schedule air conditioning repair as soon as possible to get it back on track. But when should you schedule a repair, and what signs should you look for to indicate that a repair is necessary?

In general, it’s a good idea to avoid do-it-yourself repairs to air conditioning systems. Most AC units contain complex components, and refrigerants need to be handled by qualified professionals with training. Beyond changing the air filter and keeping the outside of the unit free of dirt and debris, it’s wise to refrain from tinkering with the air conditioning yourself. That means you should call in an expert whenever signs of trouble appear. Such signs can include, but aren’t limited to, the following:

  • The air conditioning system refuses to turn on, or doesn’t blow cool air when it does turn on.
  • The air conditioner exhibits strange noises, or sounds unusually loud when it runs.
  • The air conditioner “short cycles” or turns on and off very quickly with less than ten minutes passing between the two states.
  • Ice forms on the evaporator coils or elsewhere on the system.
  • Electric bills are unusually high, even when you don’t use a lot of extra energy in your home.
  • The air conditioning heats the house unevenly, with some areas feeling cooler or more comfortable than others.

Whatever the reason, you want to schedule air conditioning repair that fixes the problem effectively and ensures that you don’t waste money on higher costs and future repair bills. If you suspect that your AC unit is in need of repair, and want it fixed promptly, then call on Polar Bear. We specialize in air conditioning repair in Alexandria, VA, and pride ourselves on diagnosing potential problems quickly and accurately. If you suspect your air conditioning system may not be functioning at peak capacity, trust our trained experts to find the best possible solution.

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.

Alexandria, VA Air Conditioning Tip: Cutting Cooling Costs

Tuesday, July 9th, 2013

Energy prices seem to always be on the rise, which is why more and more homeowners are looking for ways to cut cooling costs. At Polar Bear, we understand that our customers want to stay cool in their homes but they don’t want to pay an arm and a leg to do it. That’s why we decided to put together a quick list of some of the things that you can do in order to reduce the amount of energy that you use to cool your home. Give us a call today if you need air conditioning repair, maintenance or installation in Alexandria, VA,  and we’ll be able to help.

  • Run the fan – Whenever it’s possible, run the fans in your home in addition to your air conditioning system. By plugging in an area fan or turning on your ceiling fans, you can make your rooms feel cooler without needing to turn down the thermostat. Fans can also help circulate the air conditioned air throughout your rooms.
  • Use curtains – During the day, keep the curtains on south face windows closed. This can help prevent solar heat gain. Installing ENERGY STAR rated windows can also make a big difference in how much the sun heats up your home during the day.
  • Use water – Our bodies produce sweat when we’re hot because as the sweat evaporates, it actually cools our body. You can use the same principle in other ways around your house. Consider soaking some towels or rags in cool water and placing them on your neck or wrists. As the water evaporates it will cool your body.
  • Install a programmable thermostat – Programmable thermostats allow you to automatically adjust the temperature in your home based on time of day. If there is a time during the day that your home is usually empty, such as when everyone is at work or school, you can program your AC to turn off. It can turn back on before you come home, which keeps you comfortable and helps you save energy.

Saving energy is good for the environment and for your wallet. Follow these simple tips to cut down on your cooling costs this summer. If you have any questions about our Alexandria, VA air conditioning services, make sure that you call Polar Bear.

Getting to Know Your Air Conditioning System: 3 Basic Components

Wednesday, June 26th, 2013

It is important that homeowners contact a licensed, qualified professional for any Northern Virginia air conditioning services they may need. However, it is also a good idea to get to know the way in which your AC operates a little better. You should never attempt to service your system on your own, but having a basic understanding of the components that make up this system is a great way to ensure that you are able to recognize any problems with its performance. Here are a few components of your air conditioning system that you may not be familiar with, but which are absolutely necessary for its successful operation. Contact Polar Bear today with any questions you may still have.

Compressor

The compressor is located in the outer unit of your air conditioning system, generally speaking. It is the compressor’s job to squeeze the refrigerant when it arrives in order to pack the molecules closer together, increasing its energy and temperature. From here the refrigerant makes its way to the condenser.

Condenser

The condenser, also housed in the outside unit of your air conditioner, is the part that has metal fins. These fins allow heat to dissipate fairly quickly, which in turn allows the refrigerant to reach a much cooler temperature. When the refrigerant leaves the condenser it is no longer a gas but a high-pressure liquid. From here, through a very tiny opening, this liquid enters the evaporator.

Evaporator

The evaporator in your AC system is where the pressure of the refrigerant drops, turning it into a gas. Heat is extracted from the air surrounding it as it evaporates, and a fan is used to circulate the air in your home blows air across the evaporator fins.  When refrigerant leaves the evaporator it heads back to the compressor to repeat the whole process.

To learn more about the components of your air conditioning system or to schedule any AC service, call the pros at Polar Bear. We are happy to help you better understand the way in which your air conditioner cools your home. Contact us today to speak with a Northern Virginia air conditioning expert on our team.

Arlington, VA AC Tip: Reasons for Inefficient Air Conditioning

Wednesday, June 19th, 2013

When the summer starts to heat up, most homeowners will start to run their air conditioners in Arlington, VA more often. This will usually cause a corresponding increase in energy usage as well. However, if you notice that your energy bills are increasing without an increase in usage, it could mean that your AC isn’t working efficiently. If you need any kind of air conditioning services in Arlington, VA, just call the experts at Polar Bear. We can fix any issue that you might be having and help you get your AC working more efficiently again quickly. Check out a few of the most common reasons why your AC might be running inefficiently.

  • Lack of maintenance – One of the best things that you can do for the efficiency of your air conditioner is to get it regularly inspected and maintained by a professional. During regular maintenance visits, your AC technicians will look for any small problems and issues that could be causing your AC unit to have to work harder than it should.  They will clean all of the parts and fix any problems which could help return some of the efficiency to your system.
  • Clogged air filter – Probably the most common cause of air conditioning inefficiency is a clogged air filter. Your AC has an air filter that is usually located near the return air vent that protects the inside from dust, dirt, insects and other pollutants. If the air filter doesn’t get changed regularly, it could get clogged and restrict the flow of air through the system. This will cause your AC to have to work harder to pull air through it and, thus, reduce the efficiency of the system. By regularly changing your air filter you could be able to make sure that your air conditioner continues to operate at peak efficiency.

For all your air conditioning installation, repair or maintenance in Arlington, VA, just call Polar Bear today.

Air Conditioning Repair in Alexandria, VA: Common Problems with Packaged Systems

Wednesday, June 5th, 2013

A packaged air conditioning unit is unique because all of the system components are packaged together in a single unit. A typical split system, on the other hand, keeps the indoor air handler/evaporator and the outdoor condenser/compressor separate. A packaged system often sits on the roof or outside away from the home. Like all AC units, however, your packaged system may encounter problems during operation that will need to be fixed by a trained professional. While professional installation and routine, preventive maintenance go a long way towards ensuring that you stay cool and comfortable during the summer, some problem are inevitable. Call Polar Bear Air Conditioning & Heating today for quality air conditioning repair in Alexandria, VA.

Let’s take a look at a few common problems with packaged systems:

  • Compressor fault: Your compressor is the engine of the packaged system. It is responsible with pressurizing and circulating the refrigerant through the coils and valve. This is what you hear kick on during start-up. However, because it is so essential to effective operation, it is vital that any problems with its operation be professionally inspected and taken care of.
  • Thermostat miscalibrated: The thermostat is the user interface of the air conditioning system. Without it, the AC would not be able to sense what temperature it is—it would simply be an on/off operation. The thermostat allows you set a desire point for the AC, but if the thermostat is not calibrated to read the temperature accurately, then it will not work properly.
  • Dirty condenser coils: The condenser coils are responsible for dissipating the thermal energy absorbed from the indoor air. The exhaust fan assists with this. But if the coils have dirt or debris on them, then this dissipation process cannot possibly be efficient. It may lead to inadequate cooling and even warm air.
  • Low refrigerant: Your refrigerant charge should remain the same throughout the service life of your AC. But if there is a leak in the coils, your refrigerant level could decline, and this leads to higher energy expenditure as well as possible system damage.

Arlington, VA Air Conditioning Installation Tips: Choosing the Right System

Tuesday, May 21st, 2013

Are you tired of paying to repair your old AC on a regular basis? Do you need a new cooling solution for your new home? Whatever your reasons for needing an air conditioning installation, you need to ensure that you get the right system for your home. This depends on numerous factors, some of which we’d like to explore in today’s post. But the most important factor is the quality of the installation itself, which should always be performed by a qualified technician. If you’re in need of air conditioning installation in Arlington, VA, call Polar Bear today!

  • Size. Bigger is not better when it comes to air conditioning. Installing the largest system you can get your hands irrespective of the size of your home will not give you even more or better performance. In fact, a system that is too large can lead to inefficient cooling, uncontrollable temperatures, and even system damage because of all the short cycling. On the other hand, a system that is too small leads to inadequate cooling performance and a system that is constantly overworking itself to get by, which can also lead to system damage. Make sure your AC fits your home.
  • Type. You’ll need to decide what type of system you want to have in your home. The central air split system is the most popular throughout the country. It involves the installation of an outdoor compressor/condenser and an indoor air handler/evaporator. These units are connects to each by a lineset, and the cooling circuit uses the temperature changes of a circulating refrigerant to remove thermal energy from your home and send cool air into your home. There is also the option of a packaged system, which house all of the components in one outdoor unit. This allows for easy access during maintenance and repairs.
  • Other considerations. Installing a digital, programmable thermostat and enrolling in a preventive maintenance program at the time of installation are both great ways to ensure that your system does not go neglected.

If you need a professional, quality air conditioning installation in Arlington, VA, look no further than the experts at Polar Bear. Call us today!

Alexandria, VA Air Conditioning Tip: How Your Air Conditioning Installation Affects its Performance

Thursday, May 16th, 2013

Are you in the market for a new air conditioner? If so, then you have an unprecedented amount of choices to make. Considering all of the different brands and types of systems that are available these days, the selection of equipment can seem like a daunting prospect. Yet, you shouldn’t overlook the importance of professional installation. No matter what type of equipment you get, if it’s not properly installed, then it simply won’t perform well. Since this is such a major investment, you would do well to ensure that your installation is carried out by an AC technician. In this post, we’d like to look at how the quality of your Alexandria, VA air conditioning installation affects performance.

  • Size: Simply put, your air conditioner needs to be appropriately sized if it is to perform well. During professional installation, your technician will perform a load calculation, which measures the potential volume of air in your home that needs to be cooled, as well as other factors. This is then compared with the BTU and tonnage ratings of the air conditioners in your budget and the process of selection begins. Even before the installation gets started, there are important decisions to be made.
  • Quality: A professional AC technician has the equipment, tools, and technical expertise to ensure that all aspects of your installation run smoothly. In order to perform satisfactorily, your AC needs to have the correct “charge,” which is the level of refrigerant that circulates throughout the coils and compressor. Moreover, all of the piping connections need to be correctly joined together so that no refrigerant leaks occur.
  • Reliability: A professionally installed air conditioner followed up with routine maintenance will churn out years of solid cooling, no matter what the outside temperature is. There’s simply no other way to rely on consistent performance from your AC than by hiring a professional.

If you have any further questions about the importance of professional air conditioning installation, then do not hesitate to get in touch with us. For comprehensive Alexandria, VA air conditioning services, call Polar Bear today!
