Why Don’t I feel Enough Heat from My Boiler?

Monday, October 6th, 2014

Boilers tend to be very efficient heating systems. No system is perfect, however, and boilers are just as susceptible to heating issues as any other system. A rare, though quite frustrating, problem is that of the boiler not producing enough heat. Let’s look at the possible causes behind this issue.

Thermostat Issues

It is quite possible that your problem doesn’t rest with the boiler at all, but with the thermostat. The thermostat is the central control for your entire heating system. If it malfunctions it can easily prevent your boiler from providing enough heat, even if the boiler is in perfect condition. Check the display to make sure that everything is set properly. If the display is correct, but the heat is still not turning on, the sensors may be off. An HVAC technician will need to check in order to make a definite diagnosis.

Low Water Level

Though rare, leaks can happen in hydronic radiant heating systems. When this occurs, the lower water supply cannot carry enough heat to effectively warm the house. As usual, a professional will need to examine your system to know for certain whether this is the case. One way to tell, though, is if you notice water pooling on your floor or dripping from your ceiling when your heating is on. It is also possible that the pipes are clogged, which will produce a similar effect.

Burner Issues

The burner is comprised of several flames that serve to keep the boiler lit during use. Over time, however, one or more of these burners may malfunction or become dirty. If this happens, those burners may stop working all together. Your boiler will still provide heat, but it will be less heat than usual because it only has a few burners to heat the water.

If your boiler seems to be underperforming, call Polar Bear Air Conditioning & Heating Inc. Our expert technicians conduct boiler repair throughout the Arlington area.

Don’t wait for your boiler to stop working altogether. Call Polar Bear Air Conditioning & Heating today, and we’ll have your boiler back to normal in no time.

The Best Time to Schedule Heating Maintenance in Arlington

Monday, August 25th, 2014

Winter is still a few months away, but the change from summer to fall will start you thinking about how to heat your home for the coming cold weather. It’s likely that the furnace or boiler in your home hasn’t come on for a few months, and during that time it may have developed dirt, dust, damage, or mechanical troubles. When you first turn the heater on to deal with the arrival of cold weather in the late fall, you don’t want to discover an unpleasant surprise when the system either works poorly—or doesn’t work at all!

To prepare your home’s heater, and yourself, for the approaching colder weather, you need to schedule heating maintenance in Arlington, VA from a professional HVAC company. When you call Polar Bear Air Conditioning & Heating Inc. to arrange for regular maintenance, you’ll receive top-quality work from the most skilled technicians around… because those are the only kind of technicians we hire.

When is the best time for heating maintenance?

Right now.

There isn’t a simpler, or better, answer than that. In general, its never too late to schedule heating maintenance—you can’t afford to skip a year—but the ideal period to have the tune-up and inspection work done is during the start of fall.

One of the reasons that this is the best time to arrange for heating maintenance is that the work calendars for HVAC companies are more open during this time of year. Between the air conditioning emergencies and installations of summer, and the many winter repair calls, the fall is a period when technicians have an easier time scheduling work when it’s convenient for customers. Don’t wait until the top maintenance companies are literally snowed-under with emergency heating calls: take advantage of the slower season.

Scheduling maintenance in early fall gives you a good buffer before the cold weather to arrange for any repairs the heater needs to have done. You can probably deal with having the heat shut off in your home for short periods of time if it’s necessary for the repair work. If you should need new heating installation, you definitely want to have some extra time to schedule the work while the weather is still warm.

Polar Bear Air Conditioning & Heating Inc. offers a Preventive Maintenance Program that will take care of both your heating and cooling systems during the year. Our technicians will do a thorough inspection of your heater in the fall to find any potential malfunctions, and then tune-up, clean, and adjust the system so it will perform at high efficiency throughout the winter.

This fall, trust to our more than a decade of experience with heating maintenance in Arlington, VA. Call Polar Bear Air Conditioning & Heating, Inc. today.

Air Conditioning Repair Question: Is My Compressor Damaged?

Monday, August 4th, 2014

The compressor is one of the most important components of your air conditioning system, but it’s also one of the parts that is most likely to fail when your air conditioner runs into problems. If you believe your compressor is faulty, you may hesitate to call an AC technician for fear of costly repairs. However, it is better to get the problem fixed with professional air conditioning repair soon than to risk irreparable damage.

The compressor is responsible for compressing, or adding pressure to, the refrigerant in its gaseous state. Refrigerant must continuously change from a gas to a liquid and back again in order to absorb and release heat from your home, so the compressor allows this process to begin before it changes to a liquid at the condenser.

Compressor problems may be caused by a number of different issues. In general, the best way to keep your compressor free of damage is by calling a maintenance technician at least once a year to inspect your system. But there are many reasons the compressor fails, and the effects may be sudden.

One of the reasons a compressor may become damaged is if there is a refrigerant leak. The components of your system are designed and sized to hold only a certain level of refrigerant. The compressor in particular suffers when refrigerant levels drop due to leaks or incorrect installation, and it may fail if not enough refrigerant can pass through.

Overheating is another common cause of compressor damage. Overheating may result from electrical damage. In general, however, if any component of your AC is damaged, your compressor has to run longer and work harder to compensate, which could cause it to wear out. Of course, a compressor will also become damaged over time, and may simply fail because it is too old to function.

So how can you tell if the air conditioning problem you’re having is compressor damage or not? This is something you should leave up to the experts. While banging noises, hard starting, and a system that won’t turn on are all good indicators of damage, these can point to other problems as well, and you may only need a small repair.

For air conditioning repair in Arlington, trust the trained and certified technicians at Polar Bear Air Conditioning & Heating Inc. Give us a call today!

How Do Packaged Air Conditioning Units Differ from Centralized Units?

Monday, July 14th, 2014

There are a lot of choices these days when it comes to choosing a type of air conditioner for your home. Many factors need to be considered, including the size of your home, what kind of energy efficiency you seek and what type of system you feel would work best for your property. One of the types of air conditioners Polar Bear Air Conditioning & Heating, Inc., installs frequently is known as a packaged air conditioning unit, and it may be a good option for your Arlington property.

What Is a Packaged Air Conditioner?

A packaged air conditioner is one in which all the components – the compressor, condenser, evaporator and blower – are all housed in a single unit. This unit is typically placed outdoors, but it can also be placed on a rooftop, in a crawlspace or in an attic space. The ductwork goes directly to the unit.

What Types of Packaged Air Conditioners Are Available?

There are 4 main types of packaged air conditioners:

  • Traditional packaged air conditioner – as described above, has a single cabinet that houses the whole system
  • Packaged heat pump – a packaged heat pump system offers both heating and cooling in the same unit
  • Packaged duel fuel – this type of packaged system offers heat pump cooling in the summer, and heat pump heating for fall and spring. When the temperature goes below freezing, this unit will utilize either gas or propane to heat your home
  • Packaged gas/electric – a packaged gas/electric system uses electricity to cool during the warm months and gas to heat during the cold months

What Are The Benefits of a Packaged System? 

  • Packaged units are self-contained
  • Can cool (and heat) large spaces easily
  • Easier to repair
  • Flexible placement

Is a Packaged Air Conditioner Right for You?

The best way to determine if a packaged air conditioning unit is the best fit for your Arlington property is to work with a trained professional. As we mentioned above, many factors need to be considered when choosing a new air conditioner, and it helps to have the experience and advice of someone who does this kind of work every day.

Call Polar Bear Air Conditioning & Heating, Inc., today and schedule an appointment with one of our trained professionals to see if a packaged air conditioning system is right for your home.

How Does a Geothermal System Cool My Home?

Friday, June 27th, 2014

Geothermal systems are as effective at keeping a home cool as they are at keeping it warm: no matter the temperature outside your walls, using a geothermal system will bring you the comfort that you need.

Although people can easily understand why geothermal power provides warmth—the earth generates heat from its core that radiates outward where it can be harnessed—the idea of using that same power to provide cooling requires a bit of more explanation. It isn’t that much different than heating a home using geothermal power, however. We think you’ll see the immense advantages of choosing geothermal cooling in Arlington, VA so you’ll have the full benefits of heating in the winter as well.

Call Polar Bear Air Conditioning & Heating Inc. if you have more questions about going geothermal. We can help you find the solution you need for year-round comfort for your family.

The operation of the geothermal heat pump

The reason that geothermal systems can heat and cool a home is that they are heat pumps. Like standard “air-source” heat pump, they move heat from one location and place it in another using the cycle of refrigerant. Unlike air-source heat pumps, which use the air as the medium for this heat exchange process, geothermal heat pumps use the ground as the medium for exchange, and the stability of underground temperatures (usually around 55°F regardless of surface weather conditions) makes them reliable and efficient.

When you turn a geothermal heat pump to cooling mode, the indoor coil acts as an evaporator: the cool refrigerant (water, in this case) extracts heat from the air and cools it down. Where does this heat go? The refrigerant removes it into a series of ground loops buried at least 6 feet in the ground. The cool 55°F assures that no matter how blisteringly hot the weather is, the heat pump will always have an easy time moving indoor heat to the ground.

When a geothermal system switches to heating mode, the process reverses, and heat come from the earth and into a home. Heat pumps are especially efficient in this mode, since no matter how ice-cold the weather gets above ground, the earth still has sufficient warmth to draw indoors.

We think that geothermal systems are a fantastic way to have the right level of comfort for your home without losing energy efficiency. But you will need to have expert installers check if geothermal cooling in Arlington, VA is a good match for your home—not every property is ideally suited to installation. Schedule an appointment with the experts at Polar Bear Air Conditioning & Heating Inc. to discover if your house is right for geothermal installation this summer.

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.

If you’re considering a split air conditioning system when replacing your old unit, talk to the experts at Polar Bear Air Conditioning & Heating Inc. Pick up the phone today to make an appointment!

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.

For more on the advantages of air cleaners, or to schedule a consultation for installation, call upon the experts at Polar Bear Air Conditioning & Heating Inc.

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!
