Has your central air conditioner suddenly stopped putting out cold air? Check inside the air handler, which is typically inside your furnace, to see if the evaporator coils are iced over. This icing over is often referred to as the air conditioner "freezing up." Potential causes can vary depending on coexisting conditions, but if the unit seems to freeze up more often when the weather is humid, the problem could be in your refrigerant.
Many people don't see heating, ventilation, and air conditioning units (HVACs) as fire hazards. However, these systems can cause fires if not properly maintained. Here are some of the possible causes of HVAC fire:
Problems with Insulation or Connections
A typical HVAC unit has many electrical parts. Examples include the condenser fan, condenser coil, unit controls, and thermostat, among others. Loose connections or damaged insulation in these parts can lead to electrical fires.
The TPR (Temperature/Pressure Relief) valve usually helps to increase water heater safety by helping to prevent explosions that occur as a result of thermal expansion. It does this by providing an opening through which excess water can escape. This usually reduces the volume of water in the heating system, thus preventing excessive build-up of pressure. Here are some of the things that you should pay attention to when it comes to your water heater's TPR valve.
At some point, the air conditioning in your home is going to break down, especially in the summer when the unit is being used the most. For this reason, you are going to have to make some repairs. However, it's not always easy to tell what types of repairs are needed. Here are four tips to help you repair your air conditioner:
Ice Droplets Can Indicate a Motor Malfunction: At some point, you may notice ice droplets on the hoses of the air conditioning.
Much of the focus when choosing cooling equipment for a home falls on the size of the AC unit and the style of the ceiling fans to be used. If this is the case in your home, you are missing a key source of cooling. While an AC unit can create cool air for use in your home, a whole-house fan can help to reduce the amount of electricity you use to meet your cooling needs.
