It seems that walking on a tile floor makes more of a pounding noise and kind of shakes the floor. More so than hard wood or carpet. At least that is my experience.
In the US, square feet. In most other countries, I would presume, square meters.
The unit for noise is decibels
Noise Unit was created in 1989.
Yes. Make sure the unit can still be serviced. Be aware you will have allot of heat and noise coming from the unit.
Yes. Tub or shower water entering the wall through loose tiles or grout can run down the pipes, through the holes the pipes are going though, and into the unit below. It is more common for water to get into the unit below from leaking shower doors or poorly used tub/shower curtains that allow water to leak out the face of the tub/shower. It then enters the gap where the tub/shower meets the floor, then builds up on the sub-floor, and eventually into the unit below.
Rule #1: Read your homeowner's policy (yes, it's tedious but it may give you an answer). More than likely, the damage CAUSED by the defective unit will be covered (floor and tiles) but the defective cooling unit will not be covered. Rule #2: Contact your insurance agent and only give them the actual facts as they occurred. Request from your agent that a claims rep contact you; try to insist that the claims rep inspect the damage (very rare nowadays). They usually have you get three estimates for repair (the floor and tiles in your case). Rule #3: Check to see if the cooling unit has a warranty and contact the manufacturer to see if you can file a claim for a defective cooler.
When choosing a floor AC unit for a large room, consider the cooling capacity, energy efficiency, noise level, size and portability, and additional features like programmable settings and air purifying capabilities.
If the drain line from the ac unit is tied into the sink drain line, the trap leaving the ac unit has probably run dry. Fill the trap at the ac unit with a cup of water and it should stop the noise. Assuming a proper install, kinda hard guessing about it from here without seeing it.
It will depend greatly on the thickness & install method, however a standard unit of measure would be .020 for 1/4" thick tiles which is almost the same value as Concrete at .100 for 1" thickness
If your AC unit is making a high-pitched noise, you should first check if the air filter is clean and the unit is level. If the noise persists, it's best to contact a professional HVAC technician to diagnose and fix the issue.
IF the stereo is a low-cost unit, it may not have good alernator noise suppression or may be defective. I would bet that it is defective. You may need to install a noise filter on the power lead going to the new radio. Make sure that the unit is properly grounded to the vehicle chassis.
When an AC unit makes a loud noise when turning off, it could be due to the sudden release of built-up pressure in the system, causing vibrations and rattling. This noise is often normal and not a cause for concern, but if it persists or gets louder, it may indicate a problem that needs to be addressed by a professional technician.
