Common Problems with Air Conditioners in Arlington

hot man and fanModern air conditioners in Arlington, VA are truly a remarkable feat of technological design and manufacture. The latest units pack an incredible amount of cooling power into a relatively compact and affordable package. Northern Virginia Homeowners should be glad to have them. Still, they do occasionally run into problems. Here are five of the most common ones and how to fix them:

Common AC Problems in Arlington and How to Fix Them

Blocked Drain – One of the most overlooked factors in the proper functioning of an air conditioner in Arlington is the catch basin and drain. All of these units – for safety reasons – have automatic cutoff mechanisms if too much water accumulates in the pan. In other words, your system will not start because it does not want you to get electrocuted. Simply, clear the drain pipe and empty the catch drain. Your AC will be up and running in no time at all.

No cooling effect – Unfortunately, homeowners can rely on AC units to do too much, especially in hot Arlington and Northern VA summers. With overuse, an HVAC unit can suffer a variety of malfunctions from coolant leakage to burned-out motors. It is best to have an HVAC unit proactively checked out by a professional at the beginning and the end of the summer season. It may seem costly in the short term but a homeowner will pay less in repairs and operating bills, and will see the useful life of their unit extended significantly.

Faulty thermostat – Although a relatively inexpensive part of the HVAC system, the thermostat is the “brains” of the operation. If it malfunctions, the entire system will not perform properly. It is possible to empirically test a thermostat to see if it’s working properly, but a trained mechanic can do the job in a fraction of the time and much more reliably.

System won’t start – With this problem, it is always the best policy to start with the obvious – check to make sure that the unit is plugged in and the breaker hasn’t been thrown. Then, try turning the thermostat onto the coolest setting. If none of these solutions work, it is again time to call in a professional.

There is no airflow –The issues related to poor airflow range from blocked or crimped air ducts through faulty baffles to damaged blowers in the main unit. Try to isolate the areas not being serviced to limit the possibilities. A blocked vent is easy to remedy and a stuck baffle not much more so. A malfunctioning air blower, however, must usually be handled by a qualified technician.

Odd noises – The compressor, the condenser and the blower as well as accessories such as dehumidifiers are all mechanical items that will eventually wear out. When they do, they tend to make noise. The same is true of an bearings or belts that facilitate their operation. Have a professional check out any unusual sounds coming from your system.
