What is A Heat Pump?

November 6, 2018

If you ask a search engine, you’ll probably get some variation of ‘a device that transfers heat from a colder area to a hotter area by using mechanical energy’. This is accurate but doesn’t give the clearest picture of what it does. Here is an explanation of what a heat pump looks like and what it does. Heat Pumps in Layman’s Terms The term ‘Heat Pump’ relates to two separate parts of one machine. There is the out-door unit, which is technically the actual heat pump part. Then there is the in-door part. This is called the air handler. Refrigerant is moved between these two parts via a piece called a Compressor. What makes a heat pump so useful is how it transfers heat instead of trying to generate it. Depending on the weather, it can either move the heat from your home or move it into your home. This way your home is a lot more energy efficient. If you have any interest in installing a heat pump or learning more about the process, feel free to call REAL HVAC Services! We’re here to help.

How Often Do I Need To Change My Air Filters?

November 3, 2018

The filters in your home, and how clean they are, can determine air quality, system efficiency, and so much more. Seeing how important clean filters are, how often do you need to change them? While there are a variety of factors going into the answer, there are common suggestions from HVAC experts. Filter Changing Recommendations From The Professionals Without any other deciding factors, most would recommend getting your filters changed every three months. If you have pets, this time drops to two months. If a member of your household has allergies, or any other type of sensitivity, this will drop again to every six weeks. Those living in the home aren’t the only deciding factors. The size of your home, its location, and how often you use the HVAC systems can play a role. A small cottage in the country won’t require as many changes in comparison to a large home in the city. If you have any questions about how often you need to change your filters, or you need to schedule an appointment to get them changed, feel free to call Real HVAC Services. We’re here to help!

What Is a SEER Rating?

November 1, 2018

There are a lot of acronyms in the HVAC lexicon, and one fairly common one is SEER. What is SEER and how does it effect your energy bills? Let’s start with the first question. SEER stands for Seasonal Energy Efficiency Ratio. Essentially it is how much of a cooling output your system has divided by all the electrical energy that goes into the unit. Both the output and the input are during the same period hence the ‘seasonal’ part of SEER. What Should My SEER Rating Be? Now on to what your rating should be. Most modern AC units are made with a minimum of a 13 SEER with the maximum getting higher all the time. If you have an older unit with a lower SEER than 13, it is highly recommended you upgrade to a newer system. Depending on the conditions of your home, you may be spending more to cool your home. It’s not just the savings which improve with a higher SEER rating. Your living situation will improve as well. Homes with a high SEER unit have a more even temperature and less humidity. In short, it is recommended your SEER is somewhere between 14 and 18....

What Does BTU Mean?

October 30, 2018

Often words or terms used in the HVAC industry have most people scratching their heads. And while BTU has been partially defined in other blogs on this website, it can be useful to explain what something is in its own article. So what does BTU mean? British Thermal Units BTU stands for British Thermal Unit. As the term ‘thermal’ suggests, BTU is a way to measure energy created through heat. One BTU equals the energy needed to heat a pound of water one degree. In other words, you’d need approximately 1,178 BTUs over an hour to boil one gallon of water starting at seventy degrees Fahrenheit. BTUs for Heating and Air Conditioning Since HVAC systems often involve the movement of heat and thermal energy, BTUs are often used to measure the amount of energy needed to heat or cool a room or home. Portable air conditioning units are a great example of systems that use BTUs. If you’re looking to find out how efficient your home is, check how many BTUs are needed to heat it. If your home is using far more than what is normal, you may be losing money on heating and cooling. If you have questions...

Why Do I Need A Humidifier

October 24, 2018

As we transition from summer to fall, it’s important to think ahead to winter. While preventative maintenance checks are in order for both your HVAC and plumbing systems, it’s critical to plan for other weather-related issues. Once the humidity of the summer and fall pass, the arid nature of winter must be addressed. Your building, whether residential or commercial, has an optimal range of humidity. In the summer, you should have sixty percent or less in terms of humidity, and in winter the humidity should rest between twenty-five and forty percent. If the percentage is too high, your home will become an environment prime for mold growth. If it’s too low, some of these symptoms may start to occur: warping of wood furniture and flooring, dry or cracked skin, and nose bleeds. On top of that, you may start to experience the most wonderful trait of winter: static shock. To avoid these issues, and others like it, we recommend investing in a humidifier for your home. Before running out to buy one, you should consider which type you need. Do you need a humidifier for one room of your house? Or do you need a system that’s powerful enough to...

What is an AFUE?

October 1, 2018

Maybe you’re doing some research on replacing your furnace. Maybe your technician wrote down a term that you didn’t quite understand. Maybe your circumstance is completely different. Either way, you may be thinking: What is an AFUE? AFUE Explained AFUE, as an acronym, stands for Average Fuel Utilization Efficiency. But what does this mean in layman’s terms? An AFUE is a type of measurement used by technicians to describe how efficient a furnace is in terms of energy created versus fuel used. Here’s an example. A furnace that has an AFUE of 85% is a furnace that creates 85 BTUs (British Thermal Units) of energy for every 100 BTUs of fuel consumed. In financial terms, it’s better to have a furnace that has a higher efficiency, especially when combined with heat pump technology. The better the efficiency, the greater the chance of savings. Get Help From If you have any other questions about your current AFUE rating, want to replace your current furnace with a higher efficiency furnace, or are curious about how electric furnaces function in comparison to gas furnaces, feel free to contact Real HVAC Services. Our highly trained technicians can help you become informed about your current...

The Wonderful Invention of Air Conditioning!

September 11, 2018

Imagine having to endure a sweltering Maryland or Delaware summer without air conditioning. Sounds pretty frightening, right? Well, you can thank a man named Dr. John Gorrie for the cool air you feel when you enter an air-conditioned environment these days. Dr. John Gorrie of Florida was the first to propose a cool city. Gorrie lamented the “evils of high temperatures” and proposed that medical patients and laypeople would be much more comfortable if there was only a way to cool them off. Dr. Gorrie’s Horse-Powered Cooling System In the 1840s, Gorrie started experimenting with methods of cooling. His first invention in 1851 involved creating ice through the power of either the wind, a horse, water, or steam. Although we no longer use horses and steam to power our air conditioners, this invention was seminal in what would later become our modern-day air conditioners. A More Modern Method of Cooling It wasn’t until many years after Gorrie’s invention, in 1902, that a man named Willis Carrier took up with the idea of cooling indoor spaces once again. Carrier (a name that is today synonymous of high-end cooling systems) designed what he called an “Apparatus for Treating Air.” This system was...

Will Air Duct Cleaning Remove Mold?

July 20, 2018

One of the most pressing issues with air quality and allergy problems is mold. Mold can even be life-threatening if there is long-term exposure. Most people don’t realize that they are even breathing in mold spores inside their home, office, or school. People may only realize that they are being exposed to mold when they see it growing in or around the area or begin to have reactions to exposure. One of the most asked questions about mold exposure is whether or not the HVAC system can contain mold? Mold In The HVAC Unit? The HVAC unit and its ductwork can harbor and grow mold. The reason is that the unit sucks in air from the space, cools it, and then recirculates it throughout the interior of the home or business. If there is mold growing in any part of the area, the spore becomes airborne and are sucked into the unit. Once inside the unit, they collect and grow on the different parts of the unit including inside of the ductwork. This is one of the ways a home can be overcome with mold growth. In time, the mold can grow through all parts of the HVAC unit as...
