Remodeling a Home

One of the things that helps many people fall asleep at night is the cool air from an HVAC system. Adjusting to sleeping in the heat can be difficult when a central air conditioner breaks down, and portable fans are not always helpful when a house is too hot. Repairing a problematic air conditioner sometimes only requires the minimum work being done to return to producing cold air. However, many of the problems can be resolved a lot faster if a professional technician is hired to handle the repair. The content below explains the usual problems that HVAC systems face when it comes to cooling a house down.

Something Jams The Blower Fan

The blower fan can affect the heating and cooling part of an HVAC system if it stops turning. The fan makes the air move when you turn the thermostat on. One problem that sometimes prevents a blower fan from turning is something getting stuck in the blades. If the blades are jammed, no air movement can be produced, which means your house doesn't get cooled down when the system is running. A technician can find out if the blades are jammed or if there is something else preventing the fan from turning.

Coolant Stops Circulating As It Should

A main aspect of obtaining cold air from an HVAC system is the coolant. There are several things that can go wrong with coolant, such as not circulating through the system. Poor circulation can stem from there being a leak that is draining the coolant out of the system. If a leak is the problem, a technician will have to repair it to ensure that enough coolant goes through the system. He or she will also have to recharge the coolant to a satisfactory amount.

The Coils No Longer Do Their Jobs

An HVAC system typically has two coils, depending on the size and model that it is. Both of the coils serve an important purpose in regards to air getting cold when the system runs. For instance, the evaporator coil is needed for working with the coolant to get rid of the heat that is circulated in the heat from the blower fan. The heat must have a way to get out of your house, which is where the condenser coil comes into play. The evaporator and condenser coils might need to be cleaned or replaced if they are not working properly.
