Your AC unit will sometimes not work that great during the summer months. You can fix a lot of issues yourself, but if the following problems surface, it's just best to leave the repair up to an HVAC contractor.
The motor is one of the most important components of an AC unit as it's what powers the compressor and fans. If it will not turn on and is in fact dead, it's important to hire an HVAC contractor because they'll need to replace this dead motor with a new one. They know exactly what type of motor to bring out based on your particular HVAC system. They can recycle the dead one and put the new one in quickly. After it's set up, they can test it out to make sure it's working perfectly. You won't have to worry about a thing.
Dirty Condenser Coils
The condenser coils are located outside and thus will get dirty from time to time. It's important to clean them so that your AC unit can perform optimally throughout the warmer months. Cleaning won't be difficult if you just leave this task up to an HVAC contractor contracted by one of many hvac companies. They have special cleaning agents that will effectively remove dirt and even sticky residue, and the agents won't cause harm to the coils at all. The HVAC contractor that comes out can also inspect other components around the condenser coils while they're around this area, making sure everything looks to be in great condition.
Poor Drainage From the Drain Line
The drain line is designed to direct water away that's created by your AC unit. If this line becomes clogged, then the drain pan can fill up and then cause a lot of water damage in a quick period of time. That's why it's so important you hire a HVAC contractor the moment you realize this line is clogged. The contractor can send down a special device to break through whatever is causing the clog. Water will then be able to move freely through this line and water damage won't be something weighing heavily on your mind anymore.
The AC unit in your home will not always work great. That doesn't mean you have to perform drastic measures and buy a new AC unit. The only thing you have to do is find a competent HVAC contractor, who can troubleshoot a wide variety of issues. They'll figure out a reasonable solution that saves you future headaches and money.
