Signs Your Boiler Needs Repairs

Wednesday, December 18th, 2013

Boilers are an old and reliable form of heating technology that continues to be popular today.  They tend to be more efficient than gas heaters and don’t suffer from problems like drafts or cold spots. But like any piece of equipment, they still need repairs from time to time. The sooner you can spot signs your boiler needs repairs, the sooner you can call in a qualified Alexandria VA boiler technician to help, and the more quickly your heating system can get back up to strength.

Odd noises are the most obvious sign of a boiler in need of assistance. Kettling – a build-up of sediment in the heat exchange – can lead to rumbling noises, while low water pressure and similar problems can create bubbling or whistling noises in the system. Keep in mind that sound may travel through the system far from its source, and sounds in one part may actually indicate a problem in another part.

Leaks sometimes spring up in boiler systems, and can sometimes be spotted by puddles or moisture nearby. Keep in mind that not every leak creates puddles, however. Hot water and small leaks may combine to evaporate the leaking water, making it tougher to spot.

Problems with the thermocouple may prevent the heater from turning on, while faulty valves and build up may create low water pressure that prevents certain parts of the house from being heated properly. Any situation where a radiator doesn’t appear to work, where the heating isn’t being applied at all. And of course, any situation where the heater fails to turn on entirely is a sign that you need to call in a repair service.

Luckily, in Alexandria VA, boiler systems can be repaired by the experts at Polar Bear Air Conditioning & Heating Inc.  Our trained experts know how to spot signs your boiler needs repairs and correct it with speed and efficiency. Pick up the phone and give us a call today!

What Size Boiler Do I Need?

Tuesday, November 12th, 2013

Heating installation in Alexandria VA can be a tricky process. You need to size your boiler properly in order to heat your home with proper efficiency. If the boiler is too small, it won’t do the job. If it’s too large, it will operate inefficiently: cycling on and off too often and using up tons of unnecessary energy in the process. Considering how cold our Virginia winters get, neither option is acceptable.  “What size boiler do I need?” You ask. A trained technician can answer that (after examining your home), but a few of the basics can be found below.

Boiler “size” is measured in British Thermal Units (BTUs), which gauge how much heat the boiler generates. How many BTUs you need to heat your home depends on the size of your home, not only the square feet but the cubic feet, as tall ceilings will make a big difference in how much heat you need.

That isn’t the only factor involved in the equation, however. Your walls, roof and windows enter into it as well. In simple terms, it’s important to gauge how insulated your home is, both in terms of the insulation in your home and attic, and such factors as double glazed windows and the lack of cracks around the door. A technician will also take sunlight exposure into account: A room that gets a great deal of sunlight may be quite a bit warmer than one without. All of that can “move the bar” up or down, resulting in a smaller or larger boiler as appropriate.

Whenever the final decision, it’s important to consult with an expert to help answer the question “what size boiler do I need?” Not only can a trained technician perform exact measurements, but he or she can sit down with you to discuss you options and plan for an installation that meets your schedule. For these and other matters related to heating installation in Alexandria, VA, contact the experts at Polar Bear to help. We’ll help you determine the right size boiler for your home, then conduct the installation with professionalism and pride. Give us a call today!

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.

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.

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.

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!

McLean, VA Air Conditioning FAQ: Is Routine Maintenance Necessary

Monday, May 6th, 2013

Homeowners throughout the McLean, VA area are gearing up their air conditioning systems for the heat and humidity of the summer months. One question that we often get asked is whether routine maintenance is necessary. Well, that probably depends upon your point of view. Necessary to what? To energy efficiency, performance, indoor air quality, and possibly even your manufacturer’s warranty? Yes, it most certainly is. If you have received professional installation for your AC, then you’re well on your way to lasting home comfort, but don’t stop there. Professional routine maintenance is a cost-effective way to ensure that your home stays crisp and cool all summer long. Call the McLean, VA air conditioning pros at Polar Bear Air Conditioning & Heating today!

Professional maintenance visits involves comprehensive inspection, cleaning and tune-ups of all aspects of your system. Inspecting equipment for unsafe conditions, refrigerant leaks, electrical problems, clogged condensate drains, among others, allows your tech a close-up view of the details of your system. Cleaning of coils and filters, and lubrication of motor parts allow your AC to work as it should.

  • Performance: You can’t expect a neglected air conditioning system to perform as it should. Even high-end models that are designed to be powerful will gradually become less effective if they are not routinely maintained. Performance depends upon clean coils, efficient airflow, and the integrity of the electrical systems.
  • Energy efficiency: With good performance comes high energy efficiency. You need your AC not only to bring you cool air, but also to do it efficiently. While we cannot control the cost of energy in our area, we can control how we use it. By keeping your system clean and tuned-up on a routine basis, you can keep your energy bills to a minimum.
  • Manufacturer’s warranty: Depending on how old your AC is and who installed it, professional routine maintenance may actually be necessary in order to make sure your AC is protected. Speak to your installer or refer to your information packet for further details.
