    Exploring the Basics of How Central Air Conditioners Work

    Last updated 4 years ago

    Central air conditioning is a modern marvel that keeps your home or business comfortable and cool throughout the summer. But even though you use it daily during the cooling season, do you ever stop to wonder how central AC works? Read on for information on the basics of central air conditioning operation.

    The Basic Components
    Although central air conditioning systems vary in size and configuration, they all have the same basic components that allow them to turn hot air into cool air. All AC systems utilize a liquid refrigerant that expands and contracts based on its temperature. This refrigerant runs through two sets of coils, known as the condenser and evaporator coils, which help to capture and release heat throughout the system. To move the refrigerant, all AC systems need a compressor.

    Cooling Your Home
    The refrigerant plays a critical role in the production of cold air. As it moves through the air conditioning system, it changes from a liquid to a gas over and over. When it enters the evaporator’s coils, it absorbs heat from inside the home. As it absorbs heat, the refrigerant turns into a gas, making the evaporator’s coils super cold. When the HVAC fan blows against these cool coils, this generates cool air that is distributed throughout your air ducts.

    Cycling the Refrigerant
    After the refrigerant gas leaves the evaporator, it then travels through your HVAC’s pipes into the compressor, where it is pressurized back into a liquid. This pressurizing process generates lots of heat, which is released when the refrigerant travels through the condenser coils. These coils quickly cool the refrigerant, turning it back to a liquid. The refrigerant then enters the evaporator again to capture more heat inside the home.

    As you can imagine, failure of just one of these components can result in discomfort and huge energy inefficiencies. To keep your AC system running properly, contact Blue Dot Services of Maryland today at (410) 698-6465 to schedule professional AC repair and maintenance services for your home or business.

    Why You Should Turn Your Furnace off This Summer

    Last updated 4 years ago

    When was the last time a homeowner living on America’s mid-Atlantic coast used a furnace in order to stay cool and comfortable? Sure, winters in Maryland and Virginia can be downright freezing, but the ever more rare reprieves from summer’s sweltering heat are generally considered to be refreshing and welcome by all. Since you already know that the probability you will want to use your furnace this coming summer is zero, you should turn your furnace off now.  Here’s why:

    Save Gas
    Many homeowners assume that their furnaces do not burn any gas when they are not being used to heat their homes. Unfortunately, this is not the case with most furnaces. The pilot light that causes a gas furnace to heat up quickly when a homeowner cranks the thermostat up burns like an eternal flame. The only exemptions are system failure and manual deactivation.

    Save Money
    At present, natural gas prices in the U.S. are quite low. Cutting your pilot light for the summer months may only save you a cumulative $10 or $15, but that’s still money that would just burn up should you leave your pilot light on. Turn your pilot light off, and use the money to treat your family to an early summer ice cream!

    Save the Environment
    A more convincing reason to kill the pilot light for the summer is in the name of green living. There is no reason for that pilot light to be on, so why burn gas unnecessarily? An environmentally conscious homeowner whose furnace is on the verge of failing may want to upgrade to a modern, energy-efficient model that doesn’t have a pilot light. A heating contractor can do this for you.
