How Thermostat Trouble Can Lead to Heating Repair

Monday, October 27th, 2014

The thermostat is an essential part of your heating system: this small, usually unobtrusive device that sits on the wall near the center of a home is responsible for sending instructions to a heater (and air conditioner as well) to turn it on and off and control how long to will continue to run. Without a working thermostat, you don’t have a working heating system.

The thermostat can also malfunction in ways that will causes trouble inside the heater that may lead to it requiring repairs. This is one of the reasons you must not allow a broken thermostat—even one showing only minor miscalibrations—to remain that way for long. Call the excellent technicians at Polar Bear Air Conditioning & Heating Inc. whenever you need heating repair in Northern Virginia to restore your thermostat and heater. We have more than a decade of experience with keeping home warm throughout the winter.

The thermostat and heating repair

One of the major troubles you want to avoid from a thermostat is a miscalibration that causes the unit to misread the temperatures in a home. This can cause the heating system to start running too long, and will in turn lead to wear and tear and probably repair needs that wouldn’t have been necessary otherwise.

A thermostat miscalibration can also cause a situation known as “short-cycling.” This is when the thermostat prematurely shuts down a heater’s heating cycle before it can complete because it falsely reads that the heater has reached the target temperature. The thermostat will soon switch the heater back on again… only to have it shut off quickly once more… and on and on. This is a huge waste of power, but it also puts an incredible strain on the heater’s mechanical components. This will lead to issues such as burned-out blower motors in furnaces and heat pump and broken circulator pumps in boilers.

Another common problem with thermostats is when they lose their connection that shuts off the heater’s fan. Thermostats have separate wires to turn on and turn off the blower fan for a furnace or heat pump; if the thermostat loses its link with the wire that turns off the blower fan, the fan will run continuously, leading to it suffering from damage that will require repair needs.

Any time you notice a decline in heating power or detect the heating system turning on and off at strange times, you may have an issue in the thermostat.

Call for repairs fat the first sign of trouble. Polar Bear Air Conditioning & Heating Inc. is here to service all your needs for heating repair in Northern Virginia.

Choosing an Energy Efficient Unit for Furnace Installation in McLean, VA

Monday, October 20th, 2014

Furnaces are one of the most popular heating systems for homeowners. There are two main types of furnaces, but before choosing any kind of furnace for your home, it’s important to understand how energy efficiency is rated for furnace systems. Knowing ahead of time how a new system is supposed to perform is an important part of your furnace installation in McLean, VA. Equally important is hiring experts to perform the installation. For over 10 years, Polar Bear Air Conditioning & Heating Inc., has installed, repaired and replace multiple heating systems, and we bring this experience to every job we do.

What Is AFUE?

AFUE stands for annual fuel utilization efficiency. AFUE is the measure of a furnace’s efficiency in converting fuel to energy. As such, the higher an AFUE rating, the more efficient a particular system will be. One thing to understand about efficiency ratings is that they do not indicate that a system will heat better than another; what the efficiency rating tells you is that a particular system will heat the same as another, but will use less energy to do so. Currently, the minimum AFUE ratings for non-condensing, fossil-fueled furnaces is 78%, but this will change as of January 1, 2015 to 80%, so it’s important to note this upcoming change.

Energy Star

Another way to ensure that you install an energy efficient heating system is to look for the Energy Star sticker on the product. Whole-home appliances earn the ENERGY STAR rating by being at least 15% more energy efficient than the standard. If you have questions about using an Energy Star-labeled product, consult with your technician.

Types of Furnaces

There are two types of furnaces that Polar Bear Air Conditioning & Heating Inc., carries:

  • Gas
  • Electric

Both can efficiently heat your home, but the heating is slightly different as gas furnaces are combustion systems and electric furnaces are not. As far as efficiency is concerned, they are almost equal: a gas furnace can have an efficiency rating as high as 98% while an electric furnace can have one as high as 100%.

Which Furnace Should I Choose?

Choosing a furnace is based largely on your needs, and working with a trained professional can help you address what’s most important, including the system that will fit best in your home.

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.

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.
