How Can I Choose the Most Efficient Boiler?

Monday, November 10th, 2014

For most homeowners looking to buy a new boiler, all-around comfort and saving money are the two most important factors in selecting the right system. Of course, you want a boiler that radiates heat throughout your home and keeps your family comfortable on the harshest of winter nights. And for many homeowners, saving money upon installation is important as well. But you should also choose the heating system that is the most efficient so that you can save a lot more money over time.

Check the AFUE

AFUE stands for Annual Fuel Utilization Efficiency, and the AFUE of a furnace or boiler must be displayed on the label of any unit sold in the U.S. The AFUE is represented as a percentage, with the most efficient boilers boasting an AFUE of well over 90%. Boilers built two or three decades ago tend to have an AFUE between 50-65%, while any boiler sold in the U.S. today must have an AFUE of over 80%. This means that replacing your older boiler will already save a bundle every month over your older one. But spending a little extra on a boiler with a higher AFUE should offset the initial cost over time.

Make Sure It’s the Right Size

Another thing to check on is the size of a boiler. You can buy the most efficient boiler available on the market today, but if it’s the wrong size for your home, it won’t do you any good at all. Boilers must be properly sized according to several different calculations in order to provide sufficient heating and save you money over time. If the boiler is too small, you may leave it on for longer to feel comfortable and consume more energy in the process. If it’s too large, it will require a lot of energy to run in the first place.

Ask a Professional Heating Technician

Only a professional technician knows every precaution to take to make sure you have the correct size and model of boiler in your home and that it runs as efficiently as possible. Inform your heating technician about your budgetary and efficiency needs so you can end up with the right sized unit for your home and the most energy-efficient model possible for your budget.

Choosing the Right Type of Heating System for Your Home

Monday, October 13th, 2014

Replacing your heating system is a great opportunity for you and your household. Why? The installation of a new system offers you the chance to significantly increase your energy efficiency, comfort levels and, best of all, to choose a new system that may be a better fit for your home than your current system. There are a number of choices homeowners have when it comes to a new heating installation in Washington, DC, and the trained and certified technicians at Polar Bear Air Conditioning & Heating Inc., are here to help you every step of the way.

Choices of Heating Types

Here is an overview of the heating system types available from Polar Bear Air Conditioning & Heating Inc.:

Furnaces

Furnaces are one of the most widely-used heating systems in the US. Furnaces use ductwork to deliver hot air to your living spaces, so it is necessary to have ductwork in place in order to use a furnace. There are 3 main types of fuel used for furnaces:

  • Electricity
  • Oil
  • Natural Gas

Natural gas is the most popular of fuels, but not all homes have access to a natural gas fuel line; as such, it may be necessary to consider furnaces that use oil or electricity. Today’s furnaces are very energy efficient no matter what fuel is used, so choosing a specific type of furnace will depend on your needs.

Heat Pumps

Heat pumps can be a great option for homeowners looking to have one system provide both heating and cooling. Thanks to a component called a reversing valve, a heat pump can change the flow of refrigerant in your system so that it can heat or cool, depending on the mode it’s in. Heat pumps do not use fossil fuel; they only use a small amount of electricity to operate.

Packaged Units

Packaged units also offer both heating and cooling, but with different mechanics. With a packaged unit, your air conditioner is fueled by electricity, and the heating component uses natural gas. These types of units offer two different efficiency types, standard and high efficiency. Packaged systems have different capacities, so it’s important to work with a trained professional to ensure that you install a unit that offers the correct amount of heating and cooling for your home.

A new heating installation in Washington, DC, can be a great thing for you, your family and your home, and the best way to ensure that it is a great thing is to work with a trained, certified professional.

If you are ready for a new heating installation, call Polar Bear Air Conditioning & Heating Inc., today and schedule an appointment with one of our specialists.

Why Schedule Annual Maintenance for Your Heating System?

Monday, September 15th, 2014

We are in the last stretch before the cold weather arrives – is your heating system ready to go? One of the best ways to get your heating system in shape for the cold weather and get ahead of any potential problems is by scheduling a fall maintenance appointment for your heating system in Washington, DC. Maintenance offers several benefits that we’ll outline below, and as with any air conditioning services, it’s important to always hire trained professionals. Polar Bear Air Conditioning & Heating, Inc., has been helping customers in the Washington, DC area with their cooling and heating equipment for over 15 years, and we can help you get ready for this winter.

What Happens During a Maintenance Appointment?

Your Polar Bear Air Conditioning & Heating, Inc., technician will conduct the following during a routine maintenance appointment:

  • Full inspection of equipment, including heat exchangers and burn assemblies.
  • Check electrical components, including wiring and terminals.
  • Lubricate all moving parts.
  • Check refrigerant levels (for heat pumps).
  • Check fan belts and adjust belt tension on covered equipment.
  • Provide written recommendations for corrective actions, if any.

Benefits of Annual Fall Maintenance

There are several important benefits to scheduling annual fall maintenance for your heating system:

  • Prevent repairs – no one wants to find out their heat isn’t working on a cold winter day. Scheduling annual maintenance helps you get ahead of possible repairs by spotting them early with the thorough inspection that occurs during a regular maintenance visit.
  • Increase energy efficiency – a tuned-up heater runs better than one that is dirty and suffering from normal wear-and-tear. When your AC runs optimally, it uses less energy.
  • Extend life of equipment – the average lifespan of a furnace is about 15 years. Keeping your heater in good working order can extend this lifespan.

One of the best ways to prepare your home for winter is by scheduling heating maintenance in Washington, DC.

Fall offers a great window of opportunity to schedule maintenance, so contact Polar Bear Air Conditioning & Heating, Inc., and make an appointment with one of our experts today.

How Technicians Size a New Air Conditioner for Installation

Monday, August 18th, 2014

Although it may seem logical, the answer isn’t “As large as can fit.” A more powerful an air conditioner doesn’t mean necessarily mean a better air conditioner. Professionals must size a new AC to accommodate a home so that it 1) provides sufficient cooling load for comfort, and 2) works efficiently without energy waste. An air conditioner that is too small will not deliver enough cooling, and one that is too large will start to “short-cycle,” turning on and off rapidly and draining energy.

The process of sizing an air conditioner is a complicated one that requires the professionals to perform a heat load calculation. We’ll explain this process to show you the importance of having AC installation experts on the job.

Polar Bear Air Conditioning & Heating Inc. has more than a dozen years of experience sizing ACs. You can trust us with your air conditioning installation in Washington, DC.

The heat load calculation

A heat load calculation combines information about how a home traps and keeps out heat to determine the cooling load necessary to keep it comfortable. Numerous criteria go into the calculation; here are some of the most important ones:

  • House volume: Square footage of a home isn’t helpful for determining its cooling needs; it’s the volume of space inside that matters.
  • Insulation: How well-insulated is the house to keep excess heat from entering? How well-insulated is the attic?
  • Number of windows and their facing: Windows allow in radiant heat from the sun, so the number of windows in a home and the direction they face is important for understanding how hot the house can get.
  • Appliances and lights: The calculation takes into account the amount of heat-producing appliances and how much heat they add to a home.
  • Number of residents: The human body creates a significant amount of heat, so the calculation must include the number of people regularly reside in the house.

Once all this data is collected, the technicians plug them into the calculation and determine how much cooling in tons an air conditioner must supply to overcome the warmth in a house without overworking. This way, they will know the ideal AC to install.

The consequences of putting in an AC that’s the wrong size are extreme, and usually the only solution to the problem is to replace completely the improperly-sized unit.

Make sure this error doesn’t occur with your new air conditioning installation in Washington, DC:

Call on the professionals at Polar Bear Air Conditioning & Heating Inc. and let us handle the work, starting with correctly sizing your new AC unit.

Air Cleaners vs. Air Purifiers: The Best Choice for Your Home

Monday, August 11th, 2014

The terms “air cleaner” and “air purifier” can bewilder first-time customers who are looking for a way to cleanse out the unhealthy particles from their home’s air. There is actually a wide range of different names for these indoor air quality systems that can mean a variety of things, so we understand why people often feel confused. We’ll try to cut through some of that cloud of confusion in this post to help you focus on what you may need when it comes to getting the healthiest air possible for your house.

For air purifiers and air cleaners in Washington, DC, you can count on Polar Bear Air Conditioning & Heating Inc. to help you navigate through the different models and choices. We will also handle the installation to make sure that the new device does the job it should for many years to come. Contact us today to set up an appointment.

Specifics of the terms “air cleaners” and “air purifiers”

Confusingly, these two terms mean that same thing technically—electronic air cleaners—but in common use, an “air cleaner” refers to a mechanical air filter, and an “air purifier” refers to an electronic device with ionization technology.

Air cleaners, i.e. air filters

Air filters use a mesh of fibers, usually made from fiberglass, to attract and trap particles in the air that flows through them. They do not require any power to run, although they must occasionally be replaced when they become too clogged with trapped contaminants. Powerful air filters, such as HEPA filters, are capable of trapping 99.97% of the particles that pass through them that are 0.3 microns or larger; they can catch smaller particles as well, although not at so effective a level.

For many homes, an air filter is sufficient to reduce the dangerous allergens and asthma triggers from the air. A professional will need to select and install the unit to make sure that it will not interfere with airflow.

Air purifiers, i.e. electronic air cleaners

Air purifiers do not use filtration technology at all to clean the air. Instead they create an electronic ionization field inside the ventilation system. This ionizes contaminating particles, which are then drawn to a set of collector plates in the cleaner, where they are trapped. Air purifiers can affect particles down to 0.1 microns, and they can trap gaseous and odor molecules—something that air filters cannot. If you have issues with odors, smoke, pesticides, carbon monoxide, etc., then an electronic air cleaner is probably your best option.

When you call on the indoor air quality experts at Polar Bear Air Conditioning & Heating Inc., you’ll find out exactly what is in your air and what system you need installed to counteract it.

Whether you need air purifiers or air cleaners in Washington, DC installed for your home, you can count on Polar Bear Air Conditioning to do the job right. Call us today.

How to Tell You Need Ductwork Repair

Monday, July 21st, 2014

Ductwork can be easily forgotten because it isn’t very visible, but problems do develop with it. Common ductwork problems can include leaks, holes, cracks, broken seals, pests, debris, and dust and dirt build-up. Clearly, a lot can happen with your air ducts, but just as other parts of your air conditioner will give an indication of developing problems, so, too, does your ductwork in Washington, DC. Here are some of the more common signs our Polar Bear technicians see when it comes to ductwork repair needs:

  • Issues with airflow – decreased air flow can mean a few things, but if all other possibilities are ruled out (such as low refrigerant or fan problems), it may be time to take a look at your ductwork and see what’s happening. Cracks, holes, broken seals, disconnections and obstructions can all constrict the air flow in your system and ultimately affect your indoor air quality.
  • Abnormal sounds – rattling, whistling and humming can all indicate that there are loose components or other issues with your ductwork; scratching and scampering sounds can be indicative of pests. All should be inspected to find the root cause.
  • Higher utility bills – have you noticed a sharp increase in your monthly energy bill but haven’t changed how you’ve been operating your AC? Faulty ductwork can account for up to 30% of air loss, which is a large amount of air to compensate for.
  • Hot and cold spots – inconsistent temperature can be an indication that air is not delivering evenly throughout your home because of issues with the ductwork.
  • Increased humidity – cracks, holes and disconnections can allow humidity and moisture into the ductwork, which then gets delivered into your home.
  • Increased dust – are you seeing more dust in your home than usual? It could be coming directly from the vent work.

Don’t Do Ductwork Repairs Yourself

Ductwork repair is complex and requires the use of certain tools you may not have or may not be familiar with. Instead of trying to repair the ductwork in your Washington DC home yourself, call an expert: Polar Bear Air Conditioning & Heating, Inc. We’ve been fabricating, installing and repairing ductwork in the Washington DC area for almost 15 years.

Don’t let your ductwork compromise the operation of your air conditioning system – call Polar Bear Air Conditioning & Heating, Inc., today.

Ways to Upgrade Your Commercial Air Conditioning in Washington, DC

Friday, May 30th, 2014

The summers in Washington, DC can bring with them heavy heat and humidity. To run a business with a comfortable workspace for employees, customers, and/or clients, you need to have an effective and efficient air conditioning system that’s up to commercial standards. Poor AC can threaten your company’s livelihood, so make sure that the system you have installed can deliver the temperatures the people in your workspace expect.

For this summer, perhaps you’re looking for change in your system. It’s time to seek options for an upgrade that will take your company to the next level of comfort, as well as energy savings. To find out how you can receive better and more efficient cooling, contact the experts in commercial air conditioning in Washington, DC at Polar Bear Air Conditioning & Heating Inc. today. We’ve cooled down local businesses since 2001.

Some upgrades for a commercial air conditioning system

  • Rooftop package units: The most popular type of AC for businesses is the package unit located on the roof. A package unit eliminates the need for the older split-systems that have two cabinets, a condenser outside and an evaporator inside. With a package unit, you have all the components in one place, which saves space and removes most of the noise to the outside of the building. Many of these systems also come with humidity controls. Package units are easier for technicians to service, another advantage.
  • High performance systems: Commercial HVAC technology is constantly advancing. If you’ve had your current AC for more than a decade, some amazing developments have come along that you may wish to take advantage of. New high-efficiency systems sometimes score SEER greater than 20—an improvement of over a third what non-high-efficiency systems rate. Although these systems are more expensive to install, they will rapidly pay for themselves, especially for a busy company that needs to run the AC during most summer days.
  • New thermostat controls: A good thermostat makes for a better air conditioning system. You probably have multiple thermostats in your workplace, all networked into a central control panel. If you have an older system without high-functioning programmable abilities and alerts to identify rooms that are too hot or too cold, then you are missing out on an opportunity for greater savings and increased comfort for everyone in your company. Call up commercial AC technicians to see how they can wire up a better thermostat system for your business.

You can expect happier workers and customers, and a utility bill that is more pleasant to look at each month.

Before the summer heat starts to ramp up, call Polar Bear Air Conditioning & Heating Inc. and improve cooling for your company in Washington, DC.

3 Noises That Indicate Air Conditioning Problems

Friday, May 9th, 2014

Air conditioning technology has not reached the stage of artificial intelligence programs that can perfectly detect operating problems, diagnose them, and then alert homeowners to what needs repairs. But ACs do have something like an early-warning system: strange noises. When you hear any sound different from the hum of the fans and the compressor, pay attention close to it. It is likely a fault that requires the work of an HAVC expert to fix. If you ignore the warning noises, the trouble will grow worse and possible cause the air conditioner to break down. A great way to prevent your air conditioner from falling into disrepair is to enroll in our maintenance program.

Here are three common noises that signal you need to call for air conditioning repair in Washington, DC. For fast local service, call Polar Bear Air Conditioning & Heating Inc. We will do the work right the first time.

3 air conditioning warning sounds

  • Hissing: This is almost certainly the sound of refrigerant escaping from a leak. Loss of refrigerant will cause the system to start losing the ability to absorb heat from inside your house. This will not only lower your comfort, but it can cause ice to develop over the coils and even damage to the compressor that can turn catastrophic. Technicians will locate the leaks and seal them, then recharge the refrigerant to its original level.
  • Groaning/grinding: Best described as “mechanical failure noises,” the sort you associate with a failing car engine. The problem is often in the motors of the air conditioner, which run the blower fans and the compressor. Loss of any of these will impair or shut down the air conditioner. If repairs reach the problem in time, they can rescue the motors. Often, the motor will need replacement.
  • Clicking: If you hear this sound when the compressor or the fans start, and the unit stutters to get going, you have a system that is “hard starting” because of electrical trouble. The most common reason for this is failing capacitors: the components that transmit voltage to the motors. Repairs will replace the capacitors or else install a hard-starting kit that will overcome the problem.

Never ignore unusual air conditioning sounds: any stress on the AC system means it is wasting energy and putting additional stress on other components. Tackle the repair when it’s isolated and less extensive, and before you need to worry about the air conditioning shutting down during one of the hottest days of the summer.

Call Polar Bear Air Conditioning & Heating Inc. to have your Washington, DC air conditioning repair job finished fast and effectively by highly trained professionals.

When to Stop Repairing Your Furnace and Replace It

Tuesday, January 14th, 2014

Our furnaces are usually things we rely on more than we think about. As long as you schedule regular maintenance, your furnace should last a good long time. Sooner or later, however, you’re going to need to put your old furnace out to pasture. Deciding when to do that can be tough, especially since buying a new furnace is a sizable investment. Here’s when to stop repairing your furnace and replace it.

The biggest sign of serious problems with your furnace stem from costs. If you find yourself calling a repair service more often than you’d like, or if the repairs are starting to add up, you may want to think about a replacement furnace. In addition, as furnaces get older, they must work harder to do their jobs, which means that your monthly heating bills may go up even if you aren’t using the furnace more often than usual.  Things may get so expensive that the monthly savings of a new unit outweigh the potential costs.

Then there’s the potential that a new system offers. Not only will it likely be a more effective unit than your old one, but it may offer options such as a variable speed fans, which can help you save energy.

All of that can be compounded by the age of the furnace. If yours is older than ten years and experiencing problems, it’s a good sign that you’ll need to think about a new one.

If you need Washington DC furnace repair service, call Polar Bear Air Conditioning, Inc. We can help you determine when it’s time to replace your furnace, and help you pick the right system for your home. Pick up the phone and give us a call today!

My Pilot Light Won’t Stay Lit: What Repairs Are Needed?

Tuesday, December 10th, 2013

Pilot lights are a necessary component of many gas furnaces. Although some furnaces today use electrical igniters to start up the gas jets along the burner, the pilot light is still the standard method for most models. As long as the pilot light is burning, the gas jets responsible for creating the heat inside your furnace will be able to come on whenever your thermostat requires heat.

A pilot light can occasionally go out because of a strong draft, in which case you should have no trouble relighting it. But if the pilot light will not stay lit, going out repeatedly, then your furnace will need an expert eye to see what’s wrong and offer solutions to repair it. Without a pilot light burning, you won’t have the heat you need to get through the winter.

When it’s time for furnace repair in Washington, DC, contact Polar Bear Air Conditioning & Heating Inc., where we’ve made a commitment since 2001 to deliver quality heating services.

Repairs for a fluttering and failing pilot light

The most common repair that technicians do to restore a pilot light is to clean off the burner unit. The pilot light requires oxygen to ignite, and if grime and dirt have coated the burner unit, it will prevent the pilot from activating. The technician will remove the burner unit to have it properly cleaned.

The trouble may come from the gas line itself. There might be blockage along the pipe, damage to a gas valve, or a safety control feature that has malfunctioned so that is activating at the wrong time. Technicians can usually handle gas flow issues… and you should never attempt to do repairs to a gas line on your own.

Some newer furnaces have electronic control systems which can malfunction and affect the pilot light. These are complex systems, and require a skilled technician to look over their circuit boards and find what is necessary to repair to restore the pilot light.

The trained technicians at Polar Bear Air Conditioning & Heating Inc. are ready to assist you with your furnace repair in Washington, DC so you’ll stay warm and safe through the winter. Call us today!
