You think anything dealing with HVAC is complicated. There is complicated work going on inside of any HVAC system. That is why serious repairs require trained professionals. However, there is much information available that can help make this topic easier to understand.
Always make sure you are up-to-date about your HVAC unit. It is important to understand what model it is and which brand it is. Also, if it has been serviced before, you should have that information handy. Your contractor will appreciate this information.
Before an HVAC expert comes to your home to do any repair work, walk around the home and check out the temps in every room. Make a list of the rooms which are comfortable and which just aren't. If you do this, it will be a great help to the future contractor, who will now be able to quickly locate the problem issue.
Be sure to regularly clean debris from external condenser units. Wind can pile up all sorts of debris against its grill. It may begin to overheat, causing massive damage.
Each spring, try cleaning the fan blades and coils on the condenser fan. Before you do anything, however, turn the power off. Then you need to get the grill popped off and get the blades out so you can clean them and your unit gently.
Lubricate the oil ports on your condenser once each year. These ports are typically covered with caps made of metal or rubber. You should select an SAE 20 oil since it is lightweight and does not contain detergent. Be sure to use just 10 drops or so, or your system may overfill.
When choosing the area for placing an outdoor compressor device, place it in a shady area. The cooler the air which goes in, the less work the unit will have to do.
Once it gets cold outside, you should turn off the outdoor condenser unit. If temps go below 60 you run the risk of damaging a unit that remains on. This will allow your system to work well every year, and that saves you quite a bit on making repairs.
Now you know all about the HVAC system. It can be difficult to get into this type of thing unless you're motivated to do well, so use this advice to get you started in the right direction. You will be happy you found this article.
