Your Unit Is Working Overtime
When you start to notice that there are some weird smells being blown out from your home's HVAC system in conjunction with the cold air, then you have a problem somewhere. Depending on the odor that you are smelling, you could be dealing with anything from ice buildup to a fan motor overheating. Prior to contacting an HVAC contractor, though, it is a good idea to be familiar with the different types of odors that you may smell from your air conditioning unit and what they could mean.
Does your air conditioner make unpleasant noises every time you turn it on? It's still blowing out cold air, but those sounds are starting to get on your nerves. This indicates you need to call an air conditioning repair company. Here are some repairs they may have to make in order to quiet your system down.

When purchasing a home that has previously been lived in by one or more occupants, most buyers will spend a few hours cleaning walls, floors, and fixtures as part of their moving in process. This is common, even though most sellers are careful to ensure their home is already clean when they move out.
But even the most fastidious rarely concern themselves with the one area of the home that may be secretly harboring decades of dirt, dust, and bacteria.
If you are purchasing a home or simply have an older air conditioning unit, you may have made an appointment to have the residential AC unit inspected. This inspection can help to tell you the condition of the air conditioning unit, if any repairs are needed, approximately how much life the unit has, or whether the professional recommends that you replace the unit. Here are a few of the most important steps that take place during a residential AC inspection appointment.
