Lots of heating/cooling ducts are metal so they conduct noise quite easily from the air-handling unit to your rooms. To break the conduction of sound, you could have a heating contractor insert flexible insulation ductwork between the heating/cooling system and the ductwork runs. If you hear a pinging or popping sound coming from the ductwork, this may be caused by thermal expansion or by air blowing past a loose flap of metal.
Track along the duct runs, listening for the sound. If you hear it, make a little dent in the sheet metal to provide a more rigid surface thats less likely to move as it heats and cools.
When room temperatures swing more than about 3 degrees F. between when the air conditioning unit goes off and on again, it typically indicates that the pump is not cycling on often enough. When room temperatures drop lower than the set temperature on the thermostat, it typically means that the thermostat is incorrectly calibrated or installed w Here it doesnt sense a proper sampling of room air.
You may be able to repair your air conditioning unit by yourself. Right here are some things to think about before you call an air conditioning repairman to guarantee you do not get an $80 or $100 charge for a small product. These are all simple steps that any homeowner can take to find and repair a small AIR CONDITIONING issue that is keeping your system from cooling.
Many individuals think that by turning their systems off and allowing their homes to get hotter during the day, they are causing their systems to run less and are for that reason, saving money, however, this is not the case. The issue is that air is not the only thing that warms up when you do this; furniture, carpet, walls, etc. will also warm up. When you get home and turn your air conditioning unit back on, it actually has to work harder and longer to get rid of all the additional heat and bring the temperature down to a comfortable level.
Keep your doors and registers open as much as possible. An effectively installed and balanced air conditioning system is created to provide and return hot or cool air evenly to and from all spaces in your house. Closing doors and supply vents, however, could disrupt this balance and cause specific spaces to become hotter or colder than others, resulting not only in discomfort, but also in decreased efficiency. It also causes atmospheric pressure to build up in your ductwork, which can possibly cause or multiply air leaks, again reducing the efficiency.
Doors to unused rooms could be closed as long as there is enough space under the door to allow for air circulation; thick carpet which brushes against the bottom of the door creates a seal of sorts. If you do decide to close off a few of your supply registers, never close off vents to more than 10 % of your overall conditioned space.
