Why Is the Outside Unit of My Dual Fuel Hybrid System Still Running?

Thursday, January 15th, 2015

Furnaces have been around for many years, and are known to be reliable and safe central heating systems. However, furnaces haven’t always been known as the most efficient systems out there. Older furnaces had a standing pilot light that remained on at all times, consuming energy even when the heating cycle was complete. Today’s furnaces are far more efficient, with an electronic ignition system that allows for at least 80% annual fuel utilization efficiency (AFUE). However, this still may not be as efficient as a heat pump.

A heat pump is an air conditioning and heating system in one, which contains both an outdoor and an indoor unit much like a traditional air conditioning system. Heat pumps are efficient because they don’t use any energy to generate heat; they just shift heat from place to place. But on a very cold day, a heat pump may not have enough power to fully heat up a home. Dual fuel hybrid systems switch between the two units when temperatures drop too low, producing some of the most efficient heating possible.

Normally, when homeowners run their heating units, no outside unit runs. This is because a traditional air conditioner contains an outdoor unit and an indoor unit, while a furnace only has an indoor component connected to the ducts. But when you have a dual fuel hybrid system, you’ll probably notice the outdoor unit continues to run, even on a very cold night. This worries some homeowners, but if you know how a heat pump works, you know this is perfectly normal.

Heat pumps use refrigerant to move heat from the outside to the inside or vice versa when you switch it into heating mode. The outside unit, which contains the compressor, a large coil, and a fan, must continue to run in order to draw in outside air and absorb heat. The unit should be able to work effectively even in very cold weather. In fact, the gas furnace shouldn’t kick in until the temperature outside reaches the balance point the heat pump can meet, which is usually below freezing.

Signs Your Ducts May Be in Need of Repair

Monday, November 10th, 2014

Good ductwork is essential to your comfort and the efficient operation of your HVAC system. Ductwork can last a long while, but it can wear down and break just like any other part of your system. Because your ductwork resides behind the walls of your home, it can be difficult to know when issues develop. To help you determine whether or not you are experiencing ductwork issues, our Air Conditioning Experts, Inc., technicians have put together a list of signs that can indicate it may be time for ductwork repairs in Norcross:

  • Uneven temperatures – when ductwork is faulty, significant air loss can occur. But this air loss isn’t equal across your home. Instead, you may experience various hot and cold spots, resulting in uneven temperatures.
  • Decreased indoor air quality – the cracks, holes and disconnections of a faulty ductwork system allow contaminants to enter directly into your home’s airflow. Signs of this are strange odors and excess dirt and dust in your home.
  • Increased energy bills – faulty ductwork can lead to significant air loss. To compensate for this loss, your HVAC system has to work harder to achieve your set temperature. Anytime your system has to work harder, it uses more energy, which you’ll pay for in your monthly energy bills.
  • Mold development – mold thrives in moist areas, and the excess moisture that enters your faulty ductwork is fertile ground for mold growth. This can be especially problematic for allergy sufferers.
  • Whistling sounds – as air escapes from the holes and cracks in your ductwork, it can create a whistling sound you may hear in your vents.
  • Loud banging sounds – it isn’t unusual for metal ductwork to expand and contract, but if you hear a loud banging sound every time your system blows air, it can indicate that a section of your ductwork has disconnected.

Hire Professionals

Ductwork systems are complex, which is why it’s important to hire trained experts to handle all of your ductwork repair.

If you see the signs of faulty ductwork, call Air Conditioning Experts, Inc., immediately to schedule an appointment for duct repairs in Norcross.

How Water Heater Maintenance Extends the Life of Your Unit

Monday, September 22nd, 2014

Water heaters are built to last a long time, but you may add years to your unit with proper maintenance. Many contractors offer water heater maintenance for customers who wish to prevent their water heaters from needing sudden repairs and want to restore some efficiency to their unit for greater energy savings.

Water heaters should last around fifteen years, though this lifespan may vary depending on the type of unit and your manufacturer. But this may only be true for most systems if they receive regular maintenance. Annual maintenance ensures that your water heater is performing as well as it possibly can. A technician will check for any current repair needs as well as any issues that may affect performance in the future. Listed below are some of the problems found during water heater maintenance that could affect the life of your unit.

  • Rusted Anode Rod: The anode rod is a small rod in your tank that helps protect the tank from rust and corrosion. This rod is meant to attract rust to itself so that your tank won’t have to take the hit, but it needs to be replaced from time to time so that the rod does not become too worn down to function.
  • Sediment in Tank: Sediment may build up in the tank as a result of hard water. A maintenance technician flushes the tank with every visit to drain the unit of any buildup. Excessive sediment affects the operation of your water heater, wearing down the tank. It may also cause clogging and reduced heating.
  • Problems with the T&P Valve: The temperature and pressure valve helps ensure proper levels in order to protect your unit and your home. If the water pressure is too high, it may damage your unit, causing it to fail prematurely. During maintenance, the technician will check to make sure the valve is accurate, reducing the chances of any unnecessary wear and tear and reducing the risk of a sudden and costly failure.

Water heater maintenance should be done by a professional who knows which problems to check for and what issues may reduce the efficiency of your unit.

When you decide it’s time to schedule water heater maintenance in Norcross, contact the professionals at Air Conditioning Experts, Inc.

Does This Sound Mean It’s Time for Air Conditioning Repair?

Monday, June 24th, 2013

You should expect a certain amount of sound from your air conditioning system. After all, it’s a mechanical system with various moving parts and types of airflow. Many homeowners throughout our service area wonder about whether their air conditioners are making the right sounds or whether they should be worried. However, sounds are notoriously subjective and really require in-person diagnosis to understand what might be going on. But it’s better to be safe than sorry. If you notice a loud or unexpected shift in the sound of your AC, chances are that there’s something wrong with its operation. If you’re in need of air conditioning repair in Atlanta, GA, don’t hesitate to call Air Conditioning Experts today.

Let’s look at a few of the most common sounds:

  • Hissing: If it sounds like there is an air leak in your ductwork, then there may indeed be a small crack, hole, or loose connection somewhere. This can happen over the years and you may need to have them sealed or otherwise repaired to cut down on energy loss. But if you hear it coming from the indoor or outdoor unit, then it may be an indication of a refrigerant leak. This is the primary cause of low refrigerant, which can lead to inadequate cooling and system damages.
  • Banging: A loud banging sound can be annoying. But beyond the inconvenient noise, it can also indicate a problem causing physical damage to your AC. There could be a bent fan blade in your blower, or some other loose component that is moving around within the housing.
  • Grinding: If you notice a grinding sound, then it is probably something in the compressor or blower motor. If the bearings are dry inside a motor, then they lack the lubrication necessary to reduce friction and thermal stress.
  • Rattling: A rattling sound can indicate an issue with a loose panel or some other loosened component that needs fastening.

There are numerous sounds your AC can make during its operation, but make sure you get any strange or unusual ones checked out as soon as possible. If you’re in need of air conditioning repair in Atlanta, GA, don’t hesitate to call Air Conditioning Experts today.
