Washington, DC Heat Pump Tip: Why Your Heat Pump Isn’t Heating

Monday, October 28th, 2013

If you have a heat pump installed in your home, you’ll expect it to fulfill both sides of its heating and cooling bargain: air conditioning during hot weather, heating during cold weather. With the chilly temperatures now crawling up on us in Washington, DC, you might find that your heat pump is failing on the “heat” promise. What might cause this, and what can you do to get the heat levels you need?

Polar Bear handles Washington, DC heat pump installation, repair, and maintenance—we know what sort of problems you may encounter with the heat pump in your home, and we are ready to help. Contact us to schedule an appointment.

Why you might not get heat from your heat pump

Before investigating any possible serious malfunctions with your heat pump, make sure that you have it set correctly. Check the thermostat to see that the pump is in “heating” mode, not “cooling.” Make certain that the current programming in the thermostat (if you have a digital, programmable model—and you should) isn’t causing it to shut off at the wrong time.

There is the possibility that the thermostat has developed a fault and is sending the wrong instructions to your heat pump: this is a common occurrence, but one that technicians will have little trouble addressing.

If the heat pump is experiencing issues, the likely reasons are a malfunctioning reversing valve or compressor. A heat pump needs two compressors and the reversing valve to change from air conditioning to heating.

Another possibility to consider is the temperature outdoors. Heat pumps draw heat from outside to warm your home. Even when it’s cold outdoors, there is still some heat available. However, at extreme cold temperatures, heat pumps will struggle to operate efficiently. This will become noticeable when the outdoor temperature drops below 35°F. Then your auxiliary heat will turn on to keep your home comfortable. However, if there is an issue with your electric resistance coils, then your heat pump will not be able to heat your home.

Another issue can be the defrost cycle. When the heat pump is absorbing heat from the outdoor air, ice can form on the evaporator coils. Usually, your heat pump will have a defrost cycle that runs periodically to melt this ice and allow your heat pump to function. However, if there is a problem with your defrost cycle, the ice can build up on the coils and prevent them from absorbing the heat from the air.

Heat pumps won’t work for all homes and all weather conditions. If you discover that your heat pump isn’t malfunctioning and simply cannot cope with the extreme cold, you may need to get a replacement model, a larger heat pump, or a back-up system.

Heat pump repairs require service from professional HVAC technicians. If you can’t explain why your heat pump has stopped giving you heat, contact us right away. With more than a decade of experience, we can find out the source of the problem and devise a solution that will restore your warm indoors as quickly as possible. Give your Washington, DC heat pump the finest care— call Polar Bear Air Conditioning & Heating!

Can I Save Money with a Heat Pump in Arlington, VA?

Monday, April 8th, 2013

Heat pumps make a great addition to any home in Arlington, VA. They are widely recognized to be one of the most energy efficient ways to cool your home, and they also work during the heating season to provide warmth and comfort. This type of flexibility allows you to save money. If you’re in the market for a new air conditioning system, consider a heat pump. Most importantly, though, make sure you opt for reliable and professional installation so you know your system will work well for years to come. If you need a heat pump in Arlington, VA, call the pros at Polar Bear Air Conditioning today!

Let’s take a look at how a heat pump works. Heat pumps work just like air conditioners. They extract warm air from your home, blow it over the cool refrigerant in the evaporator coils, and return the cooled air into your home. The refrigerant has now been pressurized by the warm air and is sent through to the compressor, where the heat exhausts outside. The cycle then repeats itself. The essential principle behind the heat pump is heat transfer, although we often think of it merely as cool air entering our homes.

But heat pumps are more versatile than your average air conditioner. They are equipped with a device that allows the refrigerant to work in reverse, so that they can draw heat from even the coldest temperature outside to warm the cold air removed from the inside of your home and thereby heat your home. This type of versatility makes them incredibly energy efficient. And that means you save money.

One of the most important things to keep in mind as you shop for heat pumps is their size. For your heat pump to operate correctly, it needs to be properly sized to your unique living space. This requires professional assessment not only of the volume of air in your living space, but perhaps also considering the placement of the heat pump equipment. Professional installation will go a long way towards making sure that your heat pump continues to save you money on your energy bill throughout the year. For more information about our Arlington, VA heat pump and air conditioning services, call Polar Bear Air Conditioning today!

Washington DC Heating Guide: How to Maintain High Efficiency Filters to Reduce Stress on Your Heat Pump

Monday, September 24th, 2012

The filter on your heat pump is an integral part of your Washington DC home’s comfort system. Without that filter, the device will quickly be subjected to an influx of debris and contaminants that can get into the machinery and the air being filtered into your home. As a result, you need to make sure you properly maintain the filters to reduce stress on your heat pump.

Change Your Filters

High efficiency filters are designed to remove as much of the airborne contaminants in the air as possible. This is fantastic for keeping your indoor air clean. But if you don’t properly maintain the filter, air quality can worsen and your heat pump is put under unnecessary stress. Specifically, the extremely tight knit filter, designed to stop nearly anything from getting through, gets clogged.

Now your Washington DC heat pump is forced to work much harder to draw the air it needs from outside and heat or cool your home. On top of that, the filter is filled with contaminants that can start to leak back into the air supply, actually making your indoor air quality worse than it would be otherwise. That’s why it is so important to clean your filters on a regular basis (for permanent filters) and replace them if they are one time use.

Recommended Filters

You have options as to which types of filters you use for your heat pump. Filters come in multiple options, from super high MERV rated filters that trap up to 99% of all contaminants as small as 0.3 microns.

Electrostatic filters are especially efficient because they extract contaminants of all types – from dust and mold to smoke and gas fumes. A good filtration system should effectively remove anything from the air without needing replacement too often.

Permanent filters tend to offer the best protection against airborne contaminants and generally need to be cleaned once a month. HEPA filters are often permanent and while each filter is different, these are often extremely effective at minimizing contaminants in the air without putting stress on your heat pump.

We all know that high efficiency filters are great to have in your home because they remove contaminants from the air. This keeps your indoor air clean and healthy by preventing pollutants from circulating throughout your forced air system. But what most people don’t know is that if you don’t maintain your air filters, they can actually cause your heat pump to work much harder. When high-efficiency filters get clogged, they can restrict airflow and cause stress to your heat pump. Not to mention making your indoor air quality worse! The contaminants that were caught by the air filter might now start getting back into the air supply, actually making your indoor air quality worse. It is easy to see why it is so important to change your air filter regularly, especially if they are high efficiency.

Washington DC Heat Pump Guide: Common Heat Pump Performance Problems

Monday, September 10th, 2012

The heat pump in your Washington DC home needs to work year round to provide heat and air conditioning. This is why you want to make sure it’s performing as efficiently as possible to save on energy costs and prevent break downs. You should schedule an annual maintenance check-up and inspection with a certified HVAC technician to test the efficiency levels.

However, there are a few common causes of performance issues to be aware of so that you can be sure your Washington DC heat pump performs at optimal levels. Call Polar Bear if you have questions about heat pump performance issues, or to make an appointment for an annual inspection and professional cleaning.

Airflow Issues

There should always be a certain amount of airflow (measured in cubic feet per minute) in your heat pump to maintain proper efficiency levels. If the airflow is less than 350 cfm per ton, it could increase your energy costs. You should make sure your HVAC contractor checks the airflow whenever your heat pump is inspected. Always keep the coils clean. Sometimes the ducts are not the right size, or the fan speed needs to be increased, but often cleaning the coils will help airflow, which is why it is important to clean and maintain the components of your heat pump. A certified technician will know what methods are best, so if you suspect an airflow problem with your heat pump, call a professional heating technician.

Air Leaks in the Duct System

Inefficient or poorly-designed duct systems may not distribute air properly throughout your home because of potential air leaks. There should always be a balance between the intake and return air in a forced air system, which helps maintain a neutral pressure within the house and increase efficiency. Some contractors argue over how tightly a house should be sealed for this reason, but if your heat pump is losing heat through leaks in the air ducts, this will greatly affect its efficiency.

Improper Refrigerant

Refrigerant leaks are another common cause of low performance levels in heat pumps. Most heat pumps already have refrigerant when they leave the factory and shouldn’t have any issues. Heat pumps that are charged with refrigerant when they are installed can sometimes have the wrong amount of refrigerant. Either too much or too little refrigerant will lower the heat pump’s efficiency and performance levels. Always check the recommended refrigerant amount or ask an HVAC technician before you add refrigerant yourself.

If the heat pump in your Washington DC home isn’t working properly, it is also affecting your heating bills. Call Polar Bear today to set up an appointment.

Heat Pump Maintenance Tips from Washington DC: What Happens When You Neglect to Maintain Your Heat Pump System

Monday, August 27th, 2012

Just like any HVAC system, the heat pump in your Washington DC home needs routine maintenance and yearly check-ups to operate as efficiently and safely as possible. You also don’t want your heat pump to wear down to the point of a major malfunction or breakdown, which can be costly to repair or may require a complete system replacement.

Here are some things that could go wrong and cost you a lot more in the end if you don’t keep up with the regular maintenance of your Washington DC heat pump.

Damage to the Compressor

The compressor in a split-system heat pump works whether you are heating or cooling your home. In the winter, the compressor reverses the flow of the refrigerant to defrost the outdoor coils, and in the summer it supplies the refrigerant to cool the home, as well as cooling the outdoor coils. Proper airflow is vital to keeping the compressor running smoothly. Filters that are not changed regularly, dirty coils, and dirty fans can all restrict airflow, which will damage the compressor. Debris around the outside components should also be cleared to allow proper airflow.

Decreased Efficiency

When dirty or broken components restrict the airflow, this damages the compressor and decreases the heat pump’s efficiency levels.  Not only is it important to clean your heat pump regularly, but you should also have it checked by a certified heating technician once a year. This will also prevent safety hazards and other hidden issues with the heat pump.

Improper Refrigerant Levels

Most heat pumps are charged with refrigerant at the factory; however, if models that are charged when they are installed are not given the right amount of refrigerant this can also affect performance levels. Refrigerant leaks and other common problems can be prevented by scheduling an annual maintenance visit with one of our qualified technicians.

Don’t wait until the heat pump in your home stops working, call Polar Bear Air Conditioning to schedule your yearly check-up today!

Pros and Cons of Various Heating Systems in Washington DC

Wednesday, January 4th, 2012

When it comes time to install a new heating system in your Washington DC home, there are a lot of options to consider. Many people get overwhelmed when confronted with all of the furnaces, boilers and heat pumps on the market these days. So, to help you get a handle on what each has to offer and which will offer you the best benefits, here is an overview of the modern heating system market.

Furnaces

Furnaces are the core of a forced air heating system and use gas, oil or electricity to heat air which is then circulated through your home by a blower in your air handler. Furnaces are among the most fuel efficient heating systems on the market today with options available at up to 95% AFUE (meaning it uses up to 95% of the fuel consumed to produce heat). They are also inexpensive to install and while they don’t last quite as long as boilers, they are highly efficient when well cared for.

Boilers

Boilers use gas, oil or electricity to heat water or steam which is then circulated through your home into radiators or baseboard heaters. The heated water or steam releases heat into your home and heats it in turn. While not quite as energy efficient as a high efficiency furnace, boiler heat is perfect for homes with existing radiators and no room for vents and ductwork. It also has less of an impact on indoor air quality since there is no air movement and boilers tend to last a very long time when well maintained.

Heat Pumps

Heat pumps are becoming increasingly popular, especially in milder climates where it rarely gets below 40 degrees F. A heat pump uses the same technology as an air conditioner to extract heat from outside using a compressor, evaporator coils, and condenser coils with refrigerant.

It is most efficient in the spring and fall when temperatures are mild, but it uses much less energy than either a boiler or furnace and it can be used in the summer to cool your home. When properly maintained, a heat pump will last 10-20 years and save quite a bit of money, though it is recommended that you have an emergency heat source for days when the temperature outside gets below 40 degrees F.

What Is the Most Efficient Way to Heat My Home? A Question from Washington

Wednesday, November 23rd, 2011

When it comes to Washington home heating, efficiency is one of the main factors most people take into consideration. There are quite a few different options in terms of home heating, including furnaces, heat pumps, and boilers, and each of these have their own set of advantages and disadvantages depending on your own particular situation.

For better or worse, there is no one system that is universally more energy efficient and effective than the others. The one that will turn out to be the best choice for you is the one that fits best with your specific heating needs, the climate you live in and the relative price of the fuel sources available to you.

For instance, if you live in a relatively moderate climate, a heat pump may very well be a good option for you. These systems are able to operate much more efficiently than furnaces because they extract heat from the air rather than generating it themselves. That means that in the winter, a heat pump can take heat from the outdoor air and pump it indoors to heat your home. In the summer, the heat pump can actually do the opposite, taking the excess heat from indoors and transferring it out to provide you with a yearlong temperature control solution.

Heat pumps generally run on electricity which can be expensive, but since they use so much less energy than something like an electric furnace, they can still be a very energy efficient home heating option. However, these systems are not as effective in areas with harsh, long winters, and so would likely require a supplemental heating system as well. Also, the lower the outside temperature, the less efficient a heat pump is going to be.

Furnaces, on the other hand, are quite effective at heating homes no matter how harsh or cold the climate. Gas furnaces are generally the most popular of the models available now, mostly because the cost of natural gas is lower in most areas compared to the cost of other potential fuels.

However, it may be worth considering an oil or electric furnace if these types of energy sources are relatively inexpensive in your area. No matter what type of furnace you get, you’ll be able to choose how energy efficient you want it to be as well, with lower efficiency 80% AFUE furnaces costing substantially less than those with an AFUE of 90% or more.

Do I Need to Supplement My Heat Pump with Another Heating System? A Question from Washington

Wednesday, October 26th, 2011

People often turn to heat pumps as a solution for their Washington home heating and cooling needs because they want a single, all-inclusive system that covers all the bases. The convenience and simplicity is part of the allure of choosing a heat pump to begin with.

However, it’s not always that simple. There are situations where a heat pump is not enough to handle the needs of the whole home. This doesn’t necessarily mean that the whole idea goes out the window, but the heat pump may need some help in the form of a supplementary heating supply.

Here are some reasons/situations that may call for a supplemental heat source in addition to a heat pump:

  1. A Particularly Cold Climate – Although heat pumps can serve as the primary heating system when temperatures drop as low as 30 degrees Fahrenheit, they have trouble keeping up when the cold snap lasts longer than a few days. In any climate where temperatures dip below this mark for a length of time, a supplemental heating system is recommended.
  2. A Large Home – Heat pumps come in many different sizes, but if yours does not have the capacity to match the size of your home, then it won’t be able to heat the whole house. It’s as simple as that. If you are installing a new heat pump, be sure to get one that is properly sized. But, if you have an existing heat pump that is overmatched by your home’s size, simply supplementing it may be the easiest solution.
  3. The Power Goes Out – A heat pumps’ use of electricity is a benefit in most situations, but unfortunately it means they are helpless when the power goes out. To avoid suffering in the winter chill when a blizzard takes out a local power line, have a backup/supplemental heat source on hand to use until the power comes back on.

Those are a few situations you may encounter in which supplementing a heat pump is a good idea. Remember, though, that each situation is different. When installing a new heat pump, consult with the professional installer beforehand to see if you should also have a supplemental heat system in addition to the heat pump. This is especially important if you live a cold climate.

What Is Forced Air Heating? A Question from Washington DC

Wednesday, October 12th, 2011

Chances are that you’ve heard the term forced air heating in Washington before, particularly if you’re in the market for a new home heating system. But what does that actually mean? The truth is that if you’re asking this question, you’re not alone. There are so many types of home heating systems out there that it’s common to be a bit confused and overwhelmed by it all.

The truth is that a forced air heating system is simply a heating system that distributes heat throughout your house using air to carry it. In this type of system, heated air travels through a system of ducts and is expelled through vents into the different rooms and areas of your home in order to maintain a particular temperature. That temperature, of course, is whatever you set your thermostat to, and when the desired temperature is reached, the heat will shut off until the temperature drops down again.

The main difference between the different types of forced air heating systems is the type of equipment that heats the air. For instance, you could have a furnace or a heat pump. All of these are capable of heating air, and when paired with a fan, blower or air handler, can distribute heated air throughout your home.

Many forced air heating systems are remarkably energy efficient and can effectively keep you home comfortable all winter long. Additionally, they are generally made to be incorporated with central air conditioning systems for year round temperature control. Heat pumps are especially convenient in this way, as they’re able to both heat and cool your home depending on the season and your home comfort needs.

Particularly if you already have ductwork in place or if you’re choosing a heating system for a new construction home, it can make a lot of sense to opt for some type of forced air heating. However, if you’re looking to replace an existing heating system in a house that doesn’t already have ductwork in place, the need to put it in can add a lot to the overall installation costs of the system.

Furnace vs. Heat Pump: A Tip From DC

Wednesday, October 5th, 2011

If you’re preparing to replace your existing heating system in Washington DC, you may very well be struggling with the question of whether to go with a furnace or a heat pump for all of your future home heating needs. Each of these systems have their own advantages and drawbacks, and once you’ve narrowed it down to one type or the other, you’ll still have a pretty wide variety of products to choose from.

Furnaces are still the most popular type of home heating equipment on the market. You can get furnaces that run on gas, oil or electricity, although gas furnaces are by far the most common type of furnace around these days. The latest models are extremely energy efficient, with AFUE ratings reaching into the high 90%s.

Like heat pumps, furnaces use ducts to transfer heated air throughout your home. They typically require regular maintenance once every year or two depending on the type of furnace you have, and they can be expected to last anywhere from 15 to 25 years when properly maintained. Most modern furnaces are also made to be compatible with a central air conditioning or cooling system as well.

Heat pumps, on the other hand, don’t generate the heat that they circulate throughout your house. Instead they are able to extract the heat from the air outside and pump it inside. This means that they use much less energy than even the most energy efficient furnaces.

However, heat pumps are only capable of heating your house comfortably when the outside temperature is above freezing. If you live in an area with particularly long and frigid winters, you’ll probably find that you need to supplement your heat pump with another heat source. Because of this, it actually makes little sense to use a heat pump in more extreme climates.

On the other hand, if you live in an area with relatively mild winters, heat pumps can be a great option. They provide a constant flow of warm air to all parts of your home and can also keep you house cool during hot summer months. To cool your home, heat pumps simply reverse the process they use to warm it. They take the heat out of your indoor air and pump it outside. This is a very effective home cooling method and makes heat pumps a great solution for year round comfort.
