Grinding, Squealing and Screeching: Interpreting the Noises Your HVAC Makes

If something is failing or going amiss with your HVAC unit, chances are, your HVAC unit is letting you know something is not quite right. However, most of the cues come in the form of sounds that many of us may overlook. If you hear your HVAC unit grinding, squealing, screeching or squeaking, it is letting you know it needs help. I was unaware of these cues and overlooked them. It ended up costing me a lot of money in repairs. I want to make sure that does not happen to other people, so I made this website. I hope you learn how to interpret the noises your HVAC unit is making so you can get it the repairs it needs before you incur a costly repair, or worse, permanently ruin your unit for good.

Cool Your Jets: What You Should Know About Portable Air Conditioners

by Billie Carlson

For many people, they likely have either a window unit or a central air conditioning system installed in their home. But not everyone needs or can afford these types of home cooling equipment. Portable air conditioners are small, easy to use, and are designed for mobility so you can move them from room to room. Before you decide to purchase one of these units from a company like Tropic Air Conditioning INC, get the facts on portable cooling.

Set Up

Installation and set up of a portable air conditioner is very simple. Since they're designed to be moved to any room in the home, most models can simply be plugged in and placed near a window. The reason their proximity to a window is important is because they must be able to transfer the exhaust outside. As an air conditioner works, it is converting warm air into cool air. This causes evaporation and this should be transferred outdoors with an included window kit. Portable units should be placed on the floor in a level, steady area of the room.

Cooling Properties

Most household models of portable AC units are designed to cool one room at a time. They are quite similar to a window unit other than the way they are installed. There are different sized options designed to cool larger or smaller rooms, but in most cases the cold air will not travel effectively from one room to another. If you would like to have extra cooling in an adjacent room, using fans to help move the cool air to another room can help. There are models available that are designed for larger, commercial spaces, but these are not recommended for the home because of their large size as well as the amount of energy they consume.

Window Kits

The window kit is an essential part of any portable air conditioner. As the unit works, it releases hot air from the back of the unit. This hot air, along with moisture, must be diverted out of the room, otherwise it will not cool it down. Window kits are installed in a nearby window and are fairly easy to use. A standard kit can fit into most standard sliding windows up to four feet wide or tall. Simply install the kit into the window and slide the window closed until it is butted up against the kit. An exhaust hose is attached to the kit that allows air to escape outside. Hoses are typically five to seven feet long so you can move the unit around within that range in the room you want to cool.
