If you are new to having central heating and air conditioning, then you might be wondering about a lot of things. Learning about the HVAC system is something that you should try to do as soon as possible. This will give you the knowledge needed to take care of it the way you should be and to catch on to problems sooner so they can be repaired before things get much worse. Here are answers to some things many ask about central HVAC systems.
What Needs to Be Done to Care for the Unit Properly?
The filter needs to be kept clean at all times when the unit is going to be being used. Also, the outside housing should be checked to make sure the surrounding area is clean and to make sure nearby bushes don't need to be trimmed back. Yearly inspections should be done, and it's a good idea to have them done before you start using it.
Can You Save Money by Closing Some Vents?
Many people make the mistake of shutting the HVAC vents in parts of the house that aren't going to be used much. They figure they will be saving money by doing this, so the system only has to heat or cool the rooms where it's needed. This is not the way the system is designed, though. Shutting the vents causes an imbalance in the pressure and can cause repair issues. Central HVAC systems are energy efficient, and they won't have to work hard to heat or cool the whole house, as long as you have the correct size of unit installed. If you have found that one or more of the vents was shut and now you are having problems with the system, then you want a repair person to come help with the issue.
Why Is There a Smell Coming From the Vents?
If you are smelling something coming from the vents, then it means there is something in the ducts. Small animals like rats or squirrels can get in the ducts with little effort. They will relieve themselves in the ducts, and they can even die there. If they die in the ducts, it can cause a very bad smell. Also, sometimes mild can grow in them and this can cause a musty smell to come from the vents. Call someone out to see what the problem is and to take care of it for you.
How Come the System Doesn’t Seem to Be Working Right?
There are many possible issues that can cause the HVAC system not to run correctly. Before you call someone to come out, make sure you have the thermostat turned on and that it is set for what you want, either 'heat' or 'cool'. Verify that the temperature you want is set right as well. If everything appears to be set the way it should be, then you need a tech to come to troubleshoot the issue and fix it.
Why Is the System Making So Much Noise?
Since you are new to using a central HVAC system, you may not know how they are supposed to sound. This can leave you wondering if everything is okay. When a central system comes on, you may hear a hum, and you will hear a whooshing sound as the air goes through the system. You should not be hearing anything like banging, thumping, squealing, grinding, or anything of this nature. If you do hear things like that, call to have someone come out.
