According to the Department of Energy, heating and cooling uses more energy and costs more money than any other system in your home – typically making up about 48% of your utility bill. No matter what kind of heating and cooling system you have in your house, you can save money and increase your comfort by properly maintaining and upgrading your equipment. By combining proper equipment maintenance and upgrades with recommended insulation, air sealing, and thermostat settings, you can save up to 30% on your energy bill while reducing environmental emissions.
Here are some tips to help you keep your furnace in top shape so you can save money while keeping your home comfortable at the same time:
Change your air filters. This simple task can end up saving the life of your furnace. Air filters are designed to collect dirt, dust, and other impurities in your indoor air. If you go months without changing them, the debris gets thicker and thicker, causing your system to work that much harder to produce warm air. And the harder your system has to work, the more energy it uses and the more money it will cost you. Also, the dirt and dust will get sucked back into the system causing it to fail – in fact, that’s one of the leading causes of furnace failure.
Make sure the capacitor is running efficiently. The capacitor is located in the fan of the furnace and is responsible for starting up the motor. It is like a car battery and has a charge. When it is below the recommended percentage, which is 5%, it needs to be changed. The motor will still come on if the charge is low, but it will pull more amps and greatly increase your energy usage and monthly bill. And once the charge gets low there is no guarantee of how long it will continue to work.
Make sure your system is shielded. A shielded system is one that has no cracks or leaks. For example, if there are small leaks in your air ducts, then the warm air will seep out and end up heating your attic AND the living portion of your home. This will cost you more money and it will also take a lot longer to reach the desired temperature inside your home.
Adjust the temperature when leaving for work. There is no need to keep your furnace running strong while your house is empty. By setting the temperature to a lower degree, you are still keeping your furnace running, but not as hard, which can amount to savings.
Maintain your system. It is important to have your furnace inspected annually during the fall. A lot of internal problems can only be diagnosed by a licensed HVAC technician, and by having your system inspected right before winter you are being proactive about finding and fixing small problems before they become big and costly.
Utilize your fireplace. Your fireplace is not there just to make your house look good. The flue in your chimney is not airtight, and when it is cold outside it is not uncommon to feel a breeze in your home coming from the fireplace. By lighting a fire you are providing heat in your home and giving a little bit of rest to your furnace because you don’t need to have the temperature set as high.
By paying attention to your thermostat and furnace, and by following the advice listed above, you should be able to maintain a warm and cozy household at an affordable price. But if you have made some changes and still notice no difference in your monthly payments, it’s time to give the expert HVAC technicians at JW East Mechanical a call. We can properly diagnose all furnace-related problems and help get your home comfortable in no time.
The HVAC system inside your home is complex. It’s composed of many different parts that work together to heat or cool your home. Today we want to discuss the different parts of a furnace and how they function. Knowing the parts of your furnace is key to keeping it in good condition.
Read on as we shed some light on identifying the most important parts of your furnace, what their purposes are, and why it’s so important to take good care of them.
Parts of a Furnace
Burners
The gas burners are ignited by a pilot flame or electronic ignition that is incorporated in most modern gas furnaces. The main function of the gas burners is to heat up cold air using heat exchangers that are made of stainless steel. Then the warm air is distributed through the ducts by a blower motor.
Blower
Run by the blower motor, this is one of the crucial parts of the entire furnace system because it helps set up the air draft that is required for the operation of the furnace itself. The blower’s main purpose is to allow for easier intake of cold air and then channel it through to the heat exchanger chamber.
Heat Exchanger
The heat exchanger is made of heavy gauge metal mixed with alloys that resist temperatures above 2000° F to accommodate the extremely high temperatures that are reached inside the combustion chamber. That’s why it’s important to perform annual inspections and examine the state of the heat exchanger on a regular basis. If not, there could be dangerous consequences.
The heat exchanger is the part of the furnace that takes carbon monoxide out of the house. Because it is usually visible and easy to spot, it needs to be regularly inspected for cracks or rusting. Noticeable damage on the outside can run the risk of causing a carbon monoxide leak inside your home, which can be deadly.
Capacitor
Capacitors store electricity and help compressors and blower motors turn on and operate. Specifically, start capacitors provide motors with a boost in starting torque. Faulty capacitors lead to overheating, intermittent motor operation, humming noises and can even cause blower motor failure.
Vents
Vents are one of the only parts that are directly visible to the homeowner. Vents are usually made of stainless steel or PVC, with PVC being most common due to its durability. The vent pipe works by carrying the exhaust gasses that are formed due to combustion outside of the home,
Igniters
This is one of the key components designed for the safety of the furnace. The flame sensors, pilot, electronic or hot surface igniters monitor the presence of the flame in the combustion chamber. If the flame in the combustion chamber goes out, these sensors stop the flow of gas into the chamber using their link up with the gas control valve.
Control Board
The control board is the brain of the entire operation. Wires attached to the board run to the motor, gas valve, ignitor, and other necessary components. It controls your furnace by telling it when to kick on the gas and at which point the fan can shut off.
Modern furnaces use integrated circuit boards to monitor the furnace’s operation. It works because of light emitting diodes that show failure codes if the gas furnace is malfunctioning in any way.
Keep Your Ears Open
Most of the parts of the furnace are usually behind a door. According to experts, a person can actually hear certain parts of the furnace working.
The furnace is made up of the blower motor, the heat exchanger, the blowers, and the control board. They are the main components of a furnace, and none of them can be seen with the naked eye. Because you can’t physically see damage, listening for it is the next best thing. If you hear a loud popping sound, or any other sounds that don’t seem right, it’s time to call a professional.
Be Smart: Consult a Pro
We recommend always calling an experienced JW East Mechanical HVAC technician to come to your home and check everything out for you. We aren’t just saying that. There are fragile and expensive parts that need to be removed or moved, and only professionals have the hands-on experience to get it done correctly and safely.
If you are experiencing any issues with your HVAC system give us a call. We also recommend a fall furnace check to keep your system operating year round. We’ll perform regular maintenance to identify any worn parts or leaks. Most breakdowns in HVAC systems happen because of deferred maintenance, so have us perform these important checks every year and avoid the stress and inconvenience of a broken heater in the middle of winter.
Will it work? Is that a strange smell? What was that sound? These are all questions that go through our minds as we turn on the heater for the first time of the year. We might not use our heater as often as those who live in other places, but we do use it. And when we need to turn it on, it’s important to have peace of mind knowing that it will work correctly. The best way to make sure your heater will work is to get an annual furnace check.
Simply stated, an annual check-up ensures that all aspects of your furnace are working correctly. The number of problems that can occur within your HVAC system are endless, which is why it’s important to have a licensed professional thoroughly inspect your unit to catch small problems before they become out of control. By doing this you will not only prolong the life of your unit, you will save money and create a more energy-efficient home.
A comprehensive furnace check should inspect the following:
Blockage in the vent or drainage system- The vent and drain are essential parts of your system. Your furnace will perform at its best and last much longer with proper drainage and vent piping care by a qualified technician.
Accumulation of dust and debris- Over time, dust and other particles will collect in your system and cause blockages and other damage. Air flow is also compromised when dust gets in the way. A professional knows the right way to get around your system and clean it properly.
Rust and corrosion- If a part needs to be replaced, don’t wait long to get it fixed. Waiting a prolonged period of time will cause additional damage to your system like rusting, which is very expensive to fix.
Dirty flame sensors- If your flame sensors are dirty, your burner cannot turn on and your furnace will not produce heat.
Physical condition- Even if the individual parts of your system are working, the physical condition of the furnace is important too. Are there corrosion spots on the outside? Is there debris pushed up against the unit? All of this will keep your system from running as efficiently as it should.
Emission of dangerous, undetectable gasses- HVAC service technicians always check the carbon monoxide levels, as well as other gasses in the system to ensure there are no leaks. Gas leaks can be extremely dangerous. A carbon monoxide leak can go undetected for a long time and can lead to serious health problems, including death.
Deemed the Silent Killer, carbon monoxide is colorless and odorless, and kills on average 169 individuals a year according to the U.S. Consumer Product Safety Commission. In a 2012 study by the National Fire Protection Association, an estimated 72,000 non-fire carbon monoxide incidents were reported between 2006 and 2010. Of those, 94 percent occurred in a home.
At JW East, we recommend a fall furnace check to keep your system operating year round. We’ll perform regular maintenance to identify any worn parts or leaks. Most breakdowns in HVAC systems happen because of deferred maintenance, so have us perform these important checks every year and avoid the stress and inconvenience of a broken heater in the middle of winter.
Hurricane season is here. And so far, we have escaped the path of some very destructive storms. But that doesn’t mean we are in the clear just yet. As we all know by now, hurricanes can strengthen at the very last minute, which sometimes means you have very little time to prepare. We recommend always being ready, not only with food and water, but also making sure your house is properly prepared to handle the storm.
Before we get into the technical stuff, we want to start by stating that a hurricane or even a bad thunderstorm can cause lightning strikes. These strikes, depending where they hit, can cause extensive damage to the HVAC system of your home. If this happens to you, the first thing you must do is assess the damage. While some signs of damage will be obvious, others will not be.
Signs of HVAC damage after a storm:
Unit is making strange noises: If you hear strange rattling or buzzing noises, this could be an indicator of a big problem. It could simply mean debris has blown in your unit from the storm, or it could be a sign of internal damage to components like the fan or compressor.
AC Unit isn’t cooling your home properly: If you notice your home not cooling like it did before the storm, chances are there is damage somewhere inside your unit. The most common reason for this is a damaged or leaking refrigerant line.
Flooded Unit: This problem is very easy to spot. If your HVAC system is not working and you see water pooled around it, then your unit has been flooded.
Electrical problems at the breaker box: Sudden electrical issues can trip a breaker. Your breaker box is the first thing you should check when your system isn’t working. But if your breaker keeps tripping after you have fixed it, you will need to call a professional.
Evidence of a power surge: Power surges are a common occurrence during hurricanes. Did lightning strike near your home? Did you lose any electronic products like a television or computer? A power surge can fry a capacitor, burn up fuses and wires, and cause compressor damage. Voltage issues can cause the most damage to your HVAC system.
“As we move into hurricane season, I would like to offer some advice on how to protect your HVAC system from voltage issues out of your control. Also, with the growing number of stand-by generators being installed, it is even more important to protect these high tech systems,” says Jim East, owner of JW East Mechanical. “The old ‘hard start kits’ that many contractors have installed in the past no longer meet the growing need to protect the high-dollar electronic components that are not only in your outdoor units, but also in the heating systems.”
We recommend installing a device that helps protect your HVAC system from dangerous high voltage strikes that come with hurricanes.
“There is not a silver bullet that fits every system,” says East. “It takes a professional to offer the right control to protect your system. One of the controls we use and recommend is made by ICM Controls. We recommend one for the cooling system and one for the heating system.”
A good protection device will do the following:
Reduce in-rush current draw necessary at startup. In-rush is the maximum instantaneous input current drawn by an electrical device when first turned on. By using a device that reduces this maximum output of energy, you will save money on your monthly bills.
Reduces loud noises on startup
Over / Under voltage monitoring. This means monitoring system health, including voltage, current, compressor startup and integrity. Upon a fault condition, it will halt operation and initiate a three-minute, anti-short cycle routine while providing diagnostic fault information by means of an LED indicator.
Compressor soft start. This will reduce the starting current of the compressor by actively controlling the current in both the run and start windings.
Now is the time to have a professional out to inspect your HVAC system. We will determine areas of vulnerability and will make recommendations to keep your system running efficiently. Call the experts at JW East today!
We have mentioned in our previous blog posts the importance of keeping the air inside your home clean and purified. According to experts, just one cubic foot of air can have more than 30 million pollutants including dust, mold spores, and allergens. Breathing in these irritants can make you sick, especially in children and the elderly. They can also trigger asthma, allergies and a variety of different respiratory problems. As an HVAC company, we understand how critical having clean air inside the home is, which is why we use air purifying products made by AprilAire.
Before we discuss how you can purify your indoor air, we want to explain why you should. The experts at AprilAire have done extensive research and come up with 8 basic benefits of having clean indoor air:
Reduce illness – Removing airborne contaminants from the home allows you and your family to breathe easily.
Eliminate pests – Pests thrive in homes with dust, dirt, and mold, which can be resolved with improved indoor air quality.
Alleviate allergies – By removing allergies from your home, your entire household will breathe better and not suffer as much from seasonal allergies.
Make your home more pet friendly – All pets produce dander, meaning there are no hypoallergenic pets. But with a purified home, most all dander and pet debris will be removed from the air.
Better sleep – Because your indoor air is clean and purified, you will no longer be affected by the sneezing, and will get better sleep.
Energy efficiency – Managing humidity in the summer or winter can drastically reduce heating and cooling costs.
Increase home value – A healthy home is less likely to be damaged by pests or humidity, and may increase property value.
Lower stress levels – In addition to better health, sleep, and energy efficiency, a healthy home requires less cleaning time. And less cleaning means less stress.
AprilAire offers a variety of products that will improve the quality of your indoor air:
