The best approach to maintaining your home's HVAC systems is to work with an HVAC service company to schedule routine checks. If that's not something you want to do, and if you aren't sure if your AC needs maintenance, there are a few ways to know if you need maintenance or repair. If your air conditioner requires repair, it isn't something that should be delayed. Sometimes, delaying repairs can mean more damage to your air conditioner or HVAC system.
A Burning Smell
Any smell coming out of your air conditioner is usually a sign that a repair is needed. Bad smells could mean a variety of things. If you have a burning smell, it is likely that one of the parts, including the main fan, could be blocked or not functioning properly. It could be the case that some type of debris has gotten in the way of a part working properly, but you'll only know if you talk to an expert who can get inside the system to evaluate the cause. Any smell from the AC likely means there is a problem that needs to be addressed promptly, and you should turn off your AC until the problem is addressed.
The Air Isn't Cold
Another sign that your air conditioner may be having issues could be if the air that it's producing isn't cool. If it is lukewarm or warm, then you could have a variety of problems. In some cases, it could mean that coolant needs to be added to the system. A less expensive reason for warm air could be that your air filter isn't clean. A dirty air filter can cause the air to smell as well, so it's important to make sure to replace a filter as recommended.
The Equipment Isn't Turning On Like Normal
Sometimes, air conditioners can get damaged from being outside. If you have noticed that your air conditioner is acting inconsistently or isn't turning on at all, it's important to get the problem looked at immediately. With an HVAC system that is governed by a computer in the house, the problem could be a computer issue. In some instances, it may just be an update in the system or a setting adjustment that needs to occur. If your system isn't turning on like normal, however, it could also be that a part has been damaged. Getting a full diagnostic analysis of the equipment and the computer system will ensure a problem gets properly diagnosed.
It's important to keep up on repairs when it comes to your AC equipment. Not doing so can lead to much more costly repairs. Some neglect can actually lead to entire air conditioning units being replaced. It can be very expensive to replace HVAC equipment, but smaller repairs are manageable when it comes to cost.
