A/C Comfort issues

Outdoor A/C Noise! What is causing it?

An air-conditioner will not work properly if the outdoor unit condenser coil looks like this! And it will make a lot of unusual noises!

 

The outdoor air conditioning unit is getting louder and louder! What causes it to get so loud?

Many things can make the cooling unit louder, but the most common is lack of service. Cleaning, adjusting and checking the operation is a must to keep the noise down and the comfort up!

Cleaning –  the air conditioner condensing coil is the first thing that must be looked at. As the dirt and debris build-up on the coil, it will cause air flow issues, so the condenser fan labors to pull the air through the coil. The labor is loud! Or louder than normal and a cleaning must be performed to eliminate or lessen the noise. (The cooling unit in the picture above had to be completely disassembled to clean, flushing it with a water hose will not work to clean it!)

Adjusting – the system charge, voltage irregularities and unwanted foreign objects can be a source. All the air conditioning parameters must be set to the manufacturers specifications or the unit will be louder than normal.

Checking  – the indoor unit must be working properly or the outdoor unit will not sound correct as well. Proper air flow across the indoor evaporator coil can cause the outdoor cooling unit compressor to make unusual noises due to over heating or in some cases getting to cold and freezing up.

Air Conditioned Air – where is it going and why am I uncomfortable?

Supply Plenum – allowing cooled or heated air to escape to the attic!

 

As you can see from these pictures there are two different air flow issues that could be causing your discomfort in your home or business.

The supply plenum supplies the conditioned air to your duct work that distributes the air into the living space or work space. If it is losing that cooled or heated  conditioned  air into the attic the system will never perform up to it’s ability.

The return plenum pulls the conditioned air back into your heating or cooling system to be reconditioned to the desired temperature you have set at the thermostat. If the return air is pulling in unconditioned air from the attic it will never be able to perform during extreme outdoor weather.   

So have your heating and cooling system inspected every season to insure your system is not trying to do something it can’t do. Heat and or Cool outdoor air!

Your system will thank you and your pocket book will thank you for the lower utility bills and most of all for your improved COMFORT!

Call A.I.R. Plus today at 405-618-2AIR or 405-421-5191 to have your comfort level checked out! Or email us at gcollins@airokc.com to schedule an inspection or tune-up. Or go to our website at airokc.com

Return Plenum sucking in hot or cold attic air!

A/C Air Flow Restriction – What is it? Why is the amount of air so slow coming out of my a/c system?

Air Flow Restriction – Loose Insulation inside the air duct system or plenum-causing air flow problems in Cooling or Heating System.

What can cause an air flow restriction in your air-conditioning or heating system? The most common reason is a dirty or clogged air filter. The next most common reason is aging air duct work and or lack of knowledge. For example: air duct dampers are installed in the duct work system and the new home owner or business owner is not aware of them, flexible duct pipe has sagged and now has a kink in the run,  there is another air filter in the system up in the attic (double filtering), the evaporator coil is older and has never been cleaned, etc.

Or it could be a unwanted object restricting the air flow in the duct work system that is causing poor air flow into the home or a particular room. See the attached picture –  this is a good example of an older system that has experienced a problem with the glue that holds the insulation to the side of the sheet metal plenum, when the glue ages it will allow the insulation to come loose and then restrict the air flow.  And ultimately your Cooling/Heating or A/C system works harder to keep you comfortable!

So if you have concerns about the amount of air flow in your home or business, call A.I.R. Plus today for an inspection.
