Arlington, VA Air Conditioning Tip: Signs of Condenser Coil Problems

Monday, April 29th, 2013

Your home air conditioning system is comprised of various components that cooperate to cool the warm indoor air of your home and dissipate the heat into the outdoor air. This heat transfer process works by the radical temperature and pressure fluctuations of a refrigerant that circulates throughout the coils, compressor, and expansion valve. However, like all mechanical systems, your AC is prone to wear and tear and may require professional repair at some point. One such kind of problem concerns the condenser coil, which sits in the weatherized outdoor unit. We’d like to review some signs of condenser coil problems in this post so that you know how to identify problems when they occur. For excellent air conditioning repair services in Arlington, VA, call OASIS Heating, Air Conditioning & Refrigeration, Inc. today!

  • Inadequate cooling: Your condenser coil works by accepting the high temperature and high pressure gas refrigerant from the compressor and dissipating its heat into the outside air. Because thermal energy naturally moves into colder air, the condenser coil circulates the refrigerant as an exhaust fan pulls the much cooler outdoor air through the outdoor unit. Unfortunately, if your condenser coil is full of dust and debris, it won’t be able to dissipate this heat effectively and this can result in adequate cooling.
  • Warm air: Another effect of a clogged or dirty condenser coil is warm air. If this thermal energy cannot dissipate, the refrigerant will not adequately cool down before reaching the expansion valve, and the result may be warm air blowing your supply ductwork, rather than crisp, cool air. Your condenser coil has to work in tandem with the rest of the components for the refrigerant cycle to operate efficiently and effectively.
  • Leak: Because of the intricacy of the coils, detecting a leak in your condenser coil can often be next to impossible without the use of professional equipment and techniques. But if you do have a leak, it can lead to all sorts of system imbalances and problems within your AC. If something just isn’t right with your AC and you can’t figure out why, call for a technician, who may be able to test your condenser coil for leaks.

These are just a handful of the signs that may indicate a problem with your condenser coils. For more information, or to schedule a professional air conditioning repair in Arlington, VA, call OASIS Heating, Air Conditioning & Refrigeration, Inc. today!

Fairfax, VA Air Conditioning Repair Tip: Preventing Damage to Your Outdoor Unit

Monday, April 22nd, 2013

Whether you have a ductless mini split, or central air system, you need to make sure that all system components are protected from dust and other debris that can impair energy efficiency and functionality. Because it resides outdoors, your compressor/condenser unit is subject to more wear and tear than the indoor components. While it’s weatherized by design, it’s important to prevent any damage whenever possible. For more information about what you can do, or to schedule Fairfax, VA air conditioning repair, call the experts at OASIS Heating, Air Conditioning & Refrigeration, Inc. today!

Your outdoor compressor/condenser needs to stay clean and clear of debris. The compressor and condenser are both located in the outdoor unit, and if there is problems with air flow then they will be unable to dissipate the heat from your home and your air conditioning system will not be able to work effectively.

During the off-season, your outdoor unit may have accumulated various organic debris on its surface. As the vegetation once more becomes prevalent during the springtime, it’s all the more important that you ensure grasses and shrubs do not encroach upon the surface of the outdoor compressor/condenser. Even seemingly minor obstructions can cause significant airflow problems. By keeping your outdoor unit clean and clear, you can prevent damage to the outdoor unit.

Arlington, VA Air Conditioning Question: How Is Air Conditioner Capacity Measured?

Monday, April 15th, 2013

If you’re in the market for a new air conditioner, then you may have learned that you’ll need a calculation of your living space in order to assess what size air conditioner you’ll need to cool your home effectively and efficiently. Bigger is not better when it comes to air conditioning. This is a common mistake, and such homeowners will pay for inefficient (and sometimes inadequate) cooling for the next decade as a result.

In this post, we’d like to review the question of how an air conditioner capacity is measured, so that you can stay informed about how your AC works. For more information, or to schedule Arlington, VA air conditioning service, contact the pros at OASIS Heating, Air Conditioning & Refrigeration, Inc. today!

Your air conditioner unit uses several measurements to determine its cooling capacity. One such unit is known as the British thermal unit (BTU). It is an international standard, and it is equal to the amount of energy required to raise the temperature of one pound of water by 1° Fahrenheit. In the world of AC terminology, a BTU stands for the amount of energy required to remove that thermal unit from the room. An associated unit of measurement is the ton. One ton of cooling capacity equals about 12,000 BTUH (BTUs per hour). Thus, if you have a 3-ton unit, it can remove about 36,000 BTUs every hour. The unit of the ton is derived somewhat roughly from how much energy it would require to melt a ton of ice uniformly over the course of 24 hours. Thus, our modern AC jargon is handed down from the days when homeowners used ice to cool their homes.

Remember that only a professional will be able to assess adequately what type of cooling capacity in BTUH and tons you will need to cool your home effectively and efficiently.

Arlington, VA Air Conditioning Tip: Energy Saving Ideas for More Efficient Cooling This Summer

Monday, April 8th, 2013

If you are looking for energy saving ideas to get more efficient cooling for your home this summer, the Arlington, VA air conditioning experts at Oasis Heating, Air Conditioning & Refrigeration, Inc. can help. In this week’s blog post, we’ll discuss some ways that you can easily save energy and lower your utility bills.

First and foremost,  upgrading to a more efficient air conditioning system can save you a lot of money this summer. This will be especially important if you are facing costly repairs. It may be more cost-effective to upgrade your system to an Energy Star model than to keep on repairing failing equipment. However, make sure that your home is ready for a high-efficiency air conditioner. This includes having your ductwork checked for air leaks and insulating or sealing your home.

One of the easiest improvements you can make to save energy is to upgrade to a programmable thermostat. A programmable thermostat allows you to set the thermostat at different temperatures at different times of the day. You can set back your AC when you are at work and then program the thermostat to turn the air conditioner back on before you get home; this ensures that your home will be nice and cool when you get home and cut down on cooling costs.

Installing a ceiling fan may be another easy way to save energy, since it helps you feel cooler allowing you to turn down your AC. Depending on the size and layout of your home, a ceiling fan may help to circulate the air conditioned air inside your home as well. Attic fans are also useful and can help with ventilation and keeping your home cool without raising utility bills.
