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.

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!

Sunday, July 8th, 2012

Why “like” or “follow” your air conditioning company on Facebook or Twitter? To communicate and get help in an emergency. We all learned the importance of social networks from the Derecho thunderstorms on June 29. At Polar Bear Air Conditioning, although our phone lines were powered by generator and our crews were working, our phone company did not have power and therefore our customers could not reach us through our main number, even forwarded to our cell phones. Over one million DC area residents also lost power in our homes, but many of us were able to travel to Wifi hot spots with power to recharge our devices and access the Internet.

For those customers who were able to access our website, we posted an emergency number on our homepage. Wouldn’t it be great in a similar State of Emergency to receive a Tweet or Facebook post from your air conditioning and heating company, with an emergency number to reach us? Polar Bear Air Conditioning will do this in all future emergencies that involve heating, air conditioning and communication issues for our customers. But we need your help. In the coming weeks, we will be contacting our customers and asking you to like us on Facebook or follow us on Twitter, or you can do that now by choosing the links on our home page. We will ask you if you only want to be contacted in emergencies, or would like to receive newsletters and special offers no more than 4 times a year. You can also opt to be contacted by email. We will never sell or share your information with 3^rd parties, and you will not receive more than 4 promotional emails a year.

We hope to not experience another Derecho for several years. However, our goal is to be ready to communicate with and help our customers through all States of Emergency in all four seasons. Have a quiet and cool summer.

Your friends at Polar Bear Air Conditioning and Heating, Inc.

Reasons Your Washington DC Heat Pump Can’t Maintain the Right Temperature

Monday, March 26th, 2012

When you set your thermostat for a certain temperature, you expect that your Washington DC heat pump will either heat or cool it to that temperature, right? When you want 72 degrees, you don’t expect to have the temperature stay stuck at 70 degrees while your heat pump struggles futilely.

Sometimes heat pumps have trouble maintaining the right temperature, especially in heating mode. It’s not uncommon, and it has a number of potential causes. Run through this checklist to see if it is something you can fix yourself:

The outdoor unit is iced up. Running a defrost cycle can usually fix this.
The outdoor unit is not running at all. Sometimes this is simple enough to fix on your own. Read the manufacturer’s instructions to troubleshoot the problem.
Too much cold air is getting in the house for the heat pump to keep up. Make sure your doors and windows are closed to keep that valuable heat inside.
Your vents are closed. It may seem obvious, but problems like this can sometimes be attributed to user error. Make sure your vents are open to allow heat in.

This is by no means an all-inclusive list, and it covers just those causes that you could potentially fix yourself. There are many other possible culprits out there that could be more sinister and require Washington DC heating and air conditioning professional to be properly repaired.

Some of these include:

The compressor is not running.
A compressor valve or reversing valve is faulty.
The thermostat is malfunctioning or needs to be recalibrated.
The refrigerant level is low or there is a problem with the flow of the refrigerant.
The heat pump needs routine maintenance.

If your heat pump is not working properly for several days, especially after you have tried some of the DIY solutions above, call Polar Bear Air Conditioning right away. Your heat pump may need repairs before a bigger problem develops.

Washington DC Heat Pump Guide: Understanding the Defrost Cycle

Wednesday, January 11th, 2012

If your Washington DC home has a heat pump, you’ll want to understand the defrost cycle to help you maintain your heat pump and troubleshoot repairs. While this is a basic guide, you should call a qualified HVAC technician if you experience major issues with your heat pump.

During the winter when a heat pump is heating your home, the cooler outdoor air that’s pumped in and heated may have excess moisture. The outdoor coil evaporates this moisture, but under certain weather conditions, frost can accumulate on the coil and decrease the overall efficiency of the heat pump. To help reduce the potential for damage from the frost, heat pumps are manufactured with a defrost cycle to melt the frost from the outdoor coil. The defrost cycle occurs often during heavy frost conditions, so check weather reports if your defrost cycle seems to be running often.

At the beginning of the defrost cycle, the heat pump switches to the cooling mode and temporarily warms up the outdoor coil until it reaches somewhere around 60° F to melt the frost from the coil. To increase the temperature of the coil, the outdoor fan is prevented from turning on until the outdoor coil reaches the desired temperature. Weather conditions and the timing device both affect the amount of time it takes for the heat pump to move through the entire defrost cycle.

In older homes, electric heating elements are sometimes installed to prevent cool air from being distributed throughout the home. This element will turn on with the defrost cycle and shut down the blower fan inside the house. If you have an older heat pump, you may want to consider upgrading to a more efficient model.

Call Polar Bear any time if you have questions about the defrost cycle for the heat pump in your Washington DC home.
