Question 1

How Does An Air Conditioner Work?

Posted by empiredd on July 31, 2017

Understanding how your air conditioner works will help you know when to call an air conditioner repair man. All air conditioners use heat transference to move energy. AC units circulate pressurized chemical refrigerant through a sealed system of tubes and chambers. One side of the system is high- pressure, and the other is low-pressure. As refrigerant passes through the low-pressure chamber (the evaporator), liquid refrigerant changes into a vapor in a process that takes heat energy out of the ambient air. The vapor carries the energy to the high-pressure chamber (the condenser). As the vapor changes back into liquid inside the condenser, the stored energy is released. A compressor pump moves the refrigerant, and a calibrated restriction in the lines maintains the pressure differential. Fans circulate air across both chambers to facilitate the heat transfer.If you have any questions or just want to learn more, ask one of our experts for a more details about the components of an air conditioner.

Why is My Air Conditioning Unit Freezing Up?

Posted by empiredd on July 31, 2017

A frozen AC unit indicates a problem. There are some common reasons for air conditioners to freeze up, but the best way to identify the issue is through a troubleshooting procedure. Freezing often occurs on older units that have been improperly maintained. Restricted airflow over the internal components, caused by dust buildup and clogged filters, can prevent an AC unit from absorbing heat efficiently. Condensation trapped along the internal components can freeze to the unit. Leaking refrigerant lines or internal damage to the working mechanical components can create pressure zones that lead to freezing conditions. While it may be possible to simply flush or clean the system to restore functionality, you should always call a qualified HVAC expert for a professional air conditioning diagnostic service before you attempt to diagnose or solve the problem on your own.

What Should I Look For When I Am Inspecting My AC Unit?

Posted by empiredd on July 31, 2017

As a homeowner, you should routinely perform basic home air conditioner maintenance to ensure that your unit is functioning safely and efficiently. Before you inspect your AC, isolate the power by switching off the breaker.Examine the mechanical and electrical components for potential problems, and take note of any loose wires, corroded contacts, signs of vermin or other red flags. Clean up any noticeable dust and change dirty or clogged filters. Next, listen to your AC unit run. A properly working unit will hum with a consistent tone. If you hear unusual mechanical noises, you’ll probably need to repair or replace your AC.Finally,test your thermostat and check the temperature of the air coming out of your vents.

Once you get to know your AC unit, you’ll be able to identify and address potential problems early.If you suspect that you need a repair – or a new unit – call a professional HVAC technician for help.

How Do I Clean My Air Ducts?

Posted by empiredd on July 31, 2017

First, locate all of your home’s vents and clear any furniture, rugs, or other objects out of the area so they don’t get dust on them. After you remove the vent cover, get a vacuum and suck all the dust, dirt, and debris out of the duct. (If the vent is high up or otherwise in an awkward spot, you may want to get someone to help hold the vacuum.) Next, wipe down the inside of the vent with a rag and soapy water. You should also check for mold; if you find any spray with vinegar or mold killing solution and then scrub it away. After you let the duct dry out, replace the cover and put everything back.

Or, if all that seems like a lot of work, you can just hire Brown Service Company to do your duct cleaning for you.

How Do I Know If My Air Ducts Need To Be Cleaned?

Posted by empiredd on July 31, 2017

There are a number of things that might indicate your ducts are getting dirty. If you smell stale or musty odors when the furnace or air conditioning runs, that’s one indicator; another is that your furnace filters quickly become dirty after changing them. If you notice excessive dust that reappears on your furniture or walls shortly after cleaning, that’s another indicator of trouble. Other problems that might indicate you need to clean the ducts include low airflow from your vents and unexplained headaches or congestion. Even if you don’t have any of these warning indicators, you should have your ducts cleaned regularly if anyone in your home has allergies or asthma; if you, your family members, or prior residents of the house are or were smokers; and if you or the prior residents kept cats, dogs, or other pets.

Do I Need To Have My Ductwork Replaced?

Posted by empiredd on July 31, 2017

In most cases, no. If the problem is low airflow or spreading dust, simply cleaning out the duct will almost always be sufficient. If you have mold, however, it depends on the type of duct—fiberboard ductwork will probably need to be replaced to eliminate the infestation, while metal ducts can just be cleaned. If you have minor leaks in your ductwork, then minor repairs should so the trick. For major problems, however, you might need to replace the duct. You’ll also need to replace your ductwork if you’re replacing your air conditioner or furnace, in order to ensure that the ducts are a good match. If the ducts don’t meet the necessary specifications of a heating or AC unit, then the warm or cool air can’t get to you, which defeats the purpose.

Is it Normal For My AC Unit To Have Condensation?

Posted by empiredd on July 31, 2017

Condensation is a perfectly normal part of a functioning air conditioner. HVAC technicians inspecting AC units for condensation look for proper drainage when performing an air conditioner trouble shooting procedure. A lack of condensation coming from your unit can signal a larger problem. As temperatures change, humidity in the air condenses on the lines and other components of your AC unit. A drain allows that water to escape. On particularly humid days, that condensation and draining can create a large puddle of water under or near your AC. A clogged drain slows or stops the water’s escape, leading to unpleasant smells, contamination, rust accumulation on metal components and corrosion of electrical connections.If you detect unusual odors coming from the AC unit or suspect that your condensation drain is clogged, have an expert perform an inspection.
