The Importance of Insulation

After living in our first home for a few years, my wife and I could tell that something was wrong. It was exceptionally difficult to regulate our indoor climate, and we constantly found ourselves adjusting the thermostat. Our house was perpetually uncomfortable, and it was really frustrating. Fortunately, because we decided to hire a professional HVAC contractor to inspect our system, we were able to detect serious insulation problems early. We decided that it might be helpful to make a website dedicated to providing free information about heating, ventilation, and air conditioning, so that other people could recognize serious issues.

Got A Noisy Window Air Conditioner? Check Out These Possible Causes

Window air conditioner units offer the great advantage of having air that is portable and still efficient enough to keep your entire home cool in most cases. However, these units are also well known for causing a little racket with small disturbances or debris. There are few things more frustrating than an aggravating air conditioner that has to make a lot of noise while it cools your home. Check out these common window unit air conditioner noises and the potential causes and solutions you need to know.

Noise: Repetitive, consistent knocking or rattling

Cause and Solution: This kind of noise is often related to the fan blades that are tucked away inside the air conditioning unit. If the blades get slightly bent out of shape, it can change the way they rotate and even cause them to brush up against the interior as they move, which results in a repetitive noise. If a knock or rattle develops that is fairly consistent in sound, it is a good idea to have an air conditioning service technician take a look and see if the fan of your window air conditioner is bent out of shape. 

Noise: Rustling and rattling noises at random times

Cause and Solution: In some cases, something will make its way into the open vents in the air conditioner and get inside where it will be tossed and tumbled around due to air flow when the unit is on. In some situations, you can remove the unit from the window and turn it face down so the air vent is pointing downward and then shake whatever debris has gotten inside out. If the unit is too large for this or you have tried to do so and it is not working, a technician can disassemble the outer shell of the air unit to remove any debris lodged inside. 

Noise: Whistling in a high-pitched tone

Cause and Solution: High-pitched whistling noises are usually an easy issue to track down and diagnose on your own. In most cases, a small piece of plastic or other thin material has become lodged somewhere where the air flow from the unit is slipping over it and it creates a telltale whistling sound. Pull off the cover to the unit after you have turned it off and see if you can find a thin piece of debris around the air vent. Make sure you run your hand along the inside of the vent where debris may not be as visible.
