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.

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...

You don’t have to spend all your money just to stay cool. Here are some energy efficiency air conditioning tips to help you through the warmer weather. 1. Make Sure You’re Keeping Your Cool Air In Your Home If your conditioned air is escaping out of your home, your AC will work harder to replace it. Not only does that increase the wear and tear on your AC, it also increases your bills. You want your cool air to stay inside. Here are a few things you can do to make sure that happens: Keep all your doors and windows closed Seal any cracks or openings where air might escape Close your blinds or curtains The better you seal everything up, the less air you will lose. Without air escaping, you will find your AC performing more efficiently while using less energy to do it. Having your air ducts checked for leaks can help a lot as well. 2.

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...

How to Size a Hot Water Heater

May 2, 2018

When you need to get a new water heater, how will you know what size to get? There are big water heaters, there are small water heaters—get one too big and you waste money, get one too small and you won’t have warm and hot water when you want it. For a tankless or traditional (tanked) water heater, one of the first things that you’ll need to determine how much demand will there be and the flow rate, which is the number of gallons per minute. How many different things might be pulling hot water at the same time? Whatever that answer is, you’ll want to have a big enough water heater to satisfy your family’s needs and requirements. Probably one of the things to keep in mind is if you’re in a shower and using another appliance, you don’t want to run out of hot water! A fairly common flow rate for a shower is 2.5 gallons per minute. Water coming from a faucet to fill a clothes washer might be .75 gallons per minute. Water heaters are normally set at 120 degrees. You can figure that normal water coming through the faucet is about 50 degrees, so it...

When is a Good Time to Get AC Maintenance?

March 30, 2018

Regular AC maintenance will keep your air conditioning in top shape so you can get through the summer months staying cool and comfortable. The best time to get AC maintenance is in the fall and spring. If you get your maintenance in the spring, you ensure it will run through the warm months. If you get the maintenance done in the fall, you will rest easy knowing that once you stop running your system in the winter, it will be ready to go again in the summer. Since you only need maintenance once a year, it’s best to decide when you are going to run your system more. If your system is just for cooling, then the spring is best. If your system is both heating and cooling, do you run it more in the summer or in the winter? Right before you run it the most is the ideal time for maintenance. When the unit gets inspected in the fall it will likely need some more cleaning, since summer can be a lot dustier than winter in many areas. Some people choose to get their system looked at twice a year for these reasons. Summer is not a good...

Why Get a Video Camera Inspection for Your Sewer?

February 16, 2018

Showers, sinks, toilets — these household fixtures can become clogged from time to time. Using a plunger is often a homeowner’s first attempt to find a solution. Thankfully, this works for small clogs. Other times, a homeowner might use a liquid drainage solution. This is also effective, to a point. What happens when a plunger or a liquid drainage solution is ineffective? The problem might not be as local as first believed. Drainage Issues If there is a drainage issue, the problem might be farther down the pipe. Sewer lines, often times, run underneath the home. The trick is to find out where the issue is. To assist in diagnosing the location of the backup, a video camera inspection should be considered. The video camera will look for the following: buildups, stoppages, a broken pipe, or even roots. Once the backup is located, work can begin to rectify the problem. Buying a New Home Another time to get a video camera inspection is when purchasing a new home. The plumbing system might work today but it’s not guaranteed to work tomorrow. A comprehensive home inspection is often conducted before a buyer closes on a home. While home inspections are common,...

Why is Backflow Prevention Important?

January 26, 2018

What is Backflow? Water is vital to your entire household. You drink it, shower in it, wash laundry with it, and water the lawn with it. However, not every source of water is the same. For many places, the pure, clear drinking water that comes from your kitchen taps is different from the water that runs through the toilet or irrigates your garden. This system can work very well as long as the different kinds of water are kept separate. However, that doesn’t always happen. When water travels through your house, it passes through many connection points. Some of these pipes connect with non-drinkable water sources. By law, all of these sources should have a one-way valve that prevents potentially contaminated water from getting into the drinking water system. However, sometimes a change in water pressure or other issue causes these valves to fail. That’s where backflow prevention comes in. Where can Backflow Affect Your House? One of the most common areas for backflow to occur is in your property’s irrigation system. Water that’s suitable for keeping your lawn lush and green may not be suitable for washing your dishes. If backflow occurs, you may find your drinking water contaminated...
