During one of our summers in Virginia, a home’s air conditioner will receive a serious workout. An AC here has to deal not only with overcoming high heat but also high humidity. (Although you can have a special dehumidifier integrated into your HVAC system to assist with this.) All this stress can lead to an air conditioner that needs repairs to keep it running effectively and efficiently.

Why is My AC Running but Not Cooling?

Friday, April 4th, 2014

If you’re asking the question “why is my AC running but not cooling?” you likely have a significant problem on your hands. The good news is that such a problem is relatively common and can often be fixed by a qualified service tech. Here in Arlington VA, our air conditioning repair experts are ready to help, but you can take the first steps by understanding some of the potential causes of the problem. We’ve listed three of the biggest ones below:

  • Low refrigerant: Refrigerant is what allows your AC to cool your home, and it needs to stay at certain set levels in order to function like it should.  If a leak springs up, it can result in a lower level of cooling. You can spot the signs by checking the evaporator coil for frost. The build-up of ice on the coils acts as a further retardant for cooling your home, since it insulates the refrigerant from the air it’s intended to cool.
  • Faulty condenser fan: The condenser fan serves a vital function in the air conditioning process. Without it the refrigerant can’t undergo the transition it needs to and the cooling process will be extremely restricted. A trained technician can repair or replace the broken motor.
  • Electrical connections: An overloaded electrical component could create problems with the air conditioner without necessarily cutting off the flow of air. In order to check on the problem, shut off power to the whole AC unit from your circuit breaker, then turn it all back on again. If the issue persists, call a repair technician to assist.

If you’re asking yourself “Why is my AC running but not cooling?” then call upon the experts at OASIS Heating A/C & Refrigeration Inc. to help. We’re based in Arlington, VA, air conditioning repair services are our specialty, and we can point out the specifics of the problem before conducting thorough and professional repairs.

Tripped Breakers and Air Conditioning Repair in Arlington, VA

Monday, September 9th, 2013

You expect your air conditioning to work hard for you in Virginia, where the warm and muggy weather can make it extremely uncomfortable inside your home without cooled air circulating through it. When your air conditioner stops working, it can be as serious a problem as having your electricity go out. Indeed, electrical issues and air conditioning problems are closely linked: a malfunctioning AC can cause blown fuses. If turning on your air conditioner causes a tripped circuit breaker, your unit probably needs immediate professional check-up and repair.

One possible cause of a tripped circuit breaker is the compressor in your AC. The compressor requires the most energy to run of any part of your air conditioning system. If your compressor is a “hard starter,” it may overload circuits and trip a breaker. To fix the problem requires fixing the wiring in the compressor or even getting a replacement. An expert can come to your home to diagnose the electrical trouble with the compressor and provide the necessary repairs to get your air conditioning working again without causing a blown fuse.

Another reason for your AC tripping a circuit breaker is problems in the capacitor. This cylindrical device does the job of transmitting voltage to the condenser to keep it operating. Broken wiring can cause the capacitor to malfunction and send a power surge that causes the tripper breaker. A professional can perform electrical tests on the capacitor to determine what steps to take to get it running properly again.

Don’t delay calling in an expert when problems like tripped circuit breakers start occurring each time you switch on your AC. Simply trying to “wait out” the trouble won’t fix anything—an air conditioner is not a self-repairing device, and it needs attention from a highly-trained HVAC professional. For Arlington, VA air conditioning repair, OASIS Heating, Air Conditioning & Refrigeration, Inc. is an excellent and dependable resource. Our NATE-certified technicians can determine the repairs you require and provide the necessary work.

Getting More Out of Your Air Conditioning in Arlington, VA

Thursday, August 29th, 2013

When it comes to air conditioning, Arlington, VA residents know the value of reliability. Our hot, muggy days  make cool comfortable air a necessity, and most of us prefer to get that air without breaking the bank in high monthly bills. You can do that by upgrading your older air conditioning to a new one, or you can do it by getting more out of your existing model. A trained expert can help you out.

Efficiency is the watchword in lowering your monthly energy bills without cutting down on the cool air you’re accustomed to. And efficiency starts with regular cleaning and maintenance. When dust and dirt build up on individual components, it affects their ability to function. Dust on the evaporator coils will impact its cooling ability, while build-up in the condensate drain can lead to water overflow in the pan. Wear and tear can take their toll as well, with old components struggling to perform their functions or flat-out breaking down in some cases. If you have a refrigerant leak, low refrigerant levels will cause issues with the cooling cycle. A regular maintenance plan can keep the unit clean and spot any potential problems before they become too large to handle without a serious service call.

You can help identify sources of trouble while they’re still small by noticing any changes in the performance of your air conditioning unit. If you sense that the air flow has dropped, if the air conditioner unit seems to stay on for longer periods of time, if the air isn’t as cool as it once was, or if you hear any unusual noises coming from the air conditioner, it may be time to call in a professional.

In particular, look for unusual spike in your monthly electric bill: as sure a sign as any that there could be an issue with your AC. If you live in Arlington, VA or any of the surrounding communities, call on the experts at OASIS Heating, Air Conditioning and Refrigeration, Inc.

Alexandria, VA Air Conditioning FAQ: What is Refrigerant?

Monday, August 5th, 2013

Refrigerant is a catch-all term referring to various types of chemicals used in air conditioning systems: necessary to cool the air in your home and generally make life more comfortable. In Alexandria, VA, air conditioning is vital during the heat and humidity of summer. How, exactly, does an AC use refrigerant? Let’s take a look.

For starters, we need to understand the sorts of properties refrigerant that makes the air conditioning process possible. Refrigerants need to be able to stay liquid when very cold (much below the freezing temperature of water, for example) in order to cool the air in your home. They also need to  have a boiling point below room temperature, so it is easy to have the refrigerant return to its gaseous form. In order to understand why these characteristics are important, you need to understand the refrigerant cycle.

In basic terms, the process works like this:

  • Gaseous refrigerant enters the AC unit’s compressor, which increases the pressure and raises the gas’s temperature.
  •  The refrigerant passes through condenser coils, dissipating the heat and returning the refrigerant to a liquid state (though keeping it under high pressure).
  • The refrigerant enters an expansion valve and passes through a set of evaporator coils. It evaporates back into gaseous form and cools the air around the coils in the process.
  • A fan blows across the coils, and the refrigerant absorb the heat from the air blowing over it, creating cool air which then passes through the duct system and into your house.
  • The refrigerant gas returns to the compressor and the process repeats itself.

Theoretically, this all takes place in a closed system, which retains the refrigerant indefinitely as it cycles through the process. In reality, however, leaks are possible. A loss of refrigerant impacts your system’s efficiency and the leak will need to be located and sealed by a licensed professional. For air conditioning service in Alexandria, VA, the technicians at OASIS Heating, Air Conditioning & Refrigeration, Inc. are here to help. We can recharge your refrigerant, identify and seal and leaks, and otherwise keep your system performing at its peak. Contact us today to set up an appointment.

Alexandria, VA Air Conditioning FAQ: What is That Grinding Sound?

Tuesday, July 16th, 2013

You never like hearing it, no matter what the situation: that grating, grinding noise of machinery parts scraping against each other. This is especially true with your air conditioning: an absolute necessity during the summer in Alexandria, VA regardless of whether you’re cooling a home or a business. Whatever the cause of it, that grinding sound likely means a visit from a qualified professional to make sure it doesn’t get worse.

Grinding sounds arise when two or more moving parts come together in ways they aren’t supposed to. With air conditioning, that probably means the fan, which may have bent or broken components striking another metal section of the unit. The fan belt, too, can cause a grinding sound when loose or broken parts start rubbing up against it. In fact, any loose screws or fittings might make a grinding noise when they come into contact with other moving parts. In some situations, the piston in the compressor may fail and need replacement.

Any number of issues can cause this sort of damage, from twigs and stones lodging in the fan array to general wear and tear that may lead to a breakdown. The good news is that it announces itself fairly clearly. You’ll never mistake that grinding noise for an air conditioning unit working like it should. That usually signals a complex problem, however, which means you need a qualified technician to give it a look, rather than attempting repairs yourself. Experienced air conditioning repair technicians can likely spot the source of the trouble very quickly, and diagnose a repair plan before the noise begins to interfere with your AC’s performance.

Alexandria, VA residents can look to OASIS Heating, Air Conditioning & Refrigeration, Inc. to get that grinding noise checked out. We make service calls throughout Northern Virginia and are fully equipped to solve any problem quickly and efficiently before it gets out of hand.

Alexandria, VA Air Conditioning Installation FAQ: Should I Go Ductless?

Tuesday, July 9th, 2013

Is it time of you to replace your air conditioning system? Are you finishing building a new home and you need an AC system for it? If so, you may be thinking about the air conditioning options that are available to you. A great option for many homeowners is a ductless mini split air conditioning system. We wanted to use this blog post to let our customers know exactly what ductless AC systems are and when they’re a good idea. Give us a call here at OASIS Heating, Air Conditioning & Refrigeration, Inc. if you have any questions or if you need professional Alexandria, VA air conditioning installation services.

Most homeowners are used to the idea of an air conditioning system using a series of ducts to circulate cool air throughout your home. But there are ductless systems that offer some pretty attractive benefits over traditional forced-air systems.

Ductless mini split air conditioning and heating systems use wall-mounted units in each room or zone of the house. Each unit circulates the air in its particular area and either cools or heats it. All the units are connected to one or two central outdoor units similar to the outdoor condensing unit that is used with traditional central AC system. The installation process is actually very simple. The outdoor unit is installed away from the home. A small hole needs to be drilled in your walls to run refrigerant tubes and electrical wires to connect the indoor units and the outdoor unit; then the indoor units just need to be mounted on the wall in an appropriate place.

Benefits of Ductless Air Conditioning

Ductless mini split air conditioning system offer some unique benefits. First, they allow homeowners to control the temperature of different areas of their house independently of each other. This could reduce energy usage because you’ll only need to cool or heat the rooms that you’re using. Second, ductless mini split AC systems don’t have the energy loss that is associated with ducts. And since they don’t use ducts, they can also help keep the air in your home clean and avoid dust build-up.

The best way to tell if a ductless mini split air conditioning system is right for you is to work with a professional Alexandria, VA air conditioning installation technician. Call OASIS Heating, Air Conditioning & Refrigeration, Inc. today.

Air Conditioning Repair in Fairfax, VA: AC Constantly Running

Thursday, June 27th, 2013

There are a few sure signs that an air conditioning system is in trouble, and an AC that runs constantly is definitely one of them. There are many different reasons why your air conditioner may be running constantly, and it is always necessary to contact a professional Fairfax, VA air conditioning repair technician if you experience this problem in your home. During the hot summer months you cannot afford to take any risks with the condition and performance of your air conditioning system. Call OASIS Heating, Air Conditioning & Refrigeration, Inc. at the first sign of trouble with your AC. Protect your comfort and the condition of your air conditioning system during the hottest time of the year.

One reason that your air conditioning system won’t stop running is simple user error. If you have set your thermostat incorrectly your AC may be struggling to reach a temperature it cannot attain. Make sure that you have not accidentally set your thermostat too low and that you have it set to “auto”. If you have the fan set to “on” then it will continue to run until you adjust the setting. Of course, not all problems with your AC will be as simple to resolve. It is also possible that your thermostat is faulty. If it is not able to read temperatures accurately then your system will not operate correctly.

Another problem that could lead to this issue is leaky ductwork. If your air conditioner is producing cold air but it is being lost en route to the different areas of your home through air leaks, it will continue to replace that lost energy. This not only has a negative impact on the comfort level in your home but can also put unnecessary strain on your system, leading to further problems and high cooling costs.

To learn more about possible system failures that could cause your AC to run constantly, call the Fairfax, VA air conditioning repair professionals at OASIS Heating, Air Conditioning & Refrigeration, Inc. Our skilled technicians will be able to determine with certainty what the issue is and how best to repair the problem.
