As a homeowner, you should expect that most of the things in your home will break down over time. Even if they don't need to be replaced, you'll still encounter numerous repair calls to a variety of professionals to come and work on your home.
One of those systems is your air conditioner, which could leave you stranded in the middle of a hot day. Below are some of the most common problems that are experienced by air conditioning systems; if you see any of them, contact your local HVAC company to schedule a residential air conditioner repair service as soon as possible.
Unit Not Turning On
Since the main job of the air conditioning system is to cool down your home, if it's not happening at all, that means that you usually have a problem with your unit's power source. This could be something as simple as a flipped breaker or a thermostat that isn't working; check either of those first, since they're much more common than homeowners realize. If it's something like a connection point between your air conditioning system and your home's energy supply, you'll need to have a technician look at it, since it requires specialized tools and experience to be done safely and effectively.
Home Not Cooling Properly
As the system ages, it's inevitable that certain rooms in your home will not get as cold as others. Usually, this comes from clogged air ducts or a system that is running harder, and thus less efficiently. A simple tune-up may be all you need, but if there is another issue, such as a fan belt that is about to give way, you'll need a residential air conditioning service to have it looked at. Alternatively, you should also check your home's air filter to see if it's clogged. Without airflow being able to move back and forth between your home and system, your house won't be able to cool down as easily.
Strange Sounds and Smells
Ideally, your air conditioning system should not make any sounds at all, apart from the clicking sound that it makes whenever the system turns on and off. If you hear rattling, whining, or a metal-on-metal sound, you need to have your system looked at before the damage gets too severe and you'll need a new residential air conditioning system installation. If you notice a musty smell coming from your air vents, mold might be forming, which can not only impact your home but also your family's health.
No matter what's happening, if you notice anything out of the ordinary, it's best to have a residential air conditioning repair specialist look at your unit sooner rather than later.
