Care for your home's central air conditioning system and it can easily last you for 12–15 years before needing replacement. Unfortunately, even with regular inspections and tune-ups, your home's cooling system could be working harder than it needs to. And when your system is working harder than it should, you may find yourself needing to make premature repairs or replacement.
By being aware of some of the most common AC problems and how to avoid them, you can take better care of your home's cooling system and keep it running smoothly for many years to come.
1. Clogged Drain Lines
Air conditioning systems produce a lot of condensation when they operate, which is why drain lines are an important part of any central AC unit. Over time, however, drainage tubes can become blocked by debris. Not only can this eventually cause damage to the unit itself, but these wet conditions can also be conducive to mold and mildew growth. If you notice any water pooling around your home's AC condenser unit (the part of the unit that is outside your home), call an HVAC repair company to address the problem right away.
2. Refrigerant Leaks
Any air conditioning system relies on refrigerant to remove heat and humidity from the air before it is delivered to your home. Over time, however, leaks in refrigerant lines can result in low levels of this important compound. If you've noticed that your AC doesn't seem to be cooling as effectively as it used to, then low refrigerant could be to blame. You'll need an HVAC specialist to come out to your home, pinpoint the source of the leak, and repair it promptly.
3. Dirty Air Filters
Here's something you can handle yourself: change your ACs air filter at least once every 90 days. A clogged air filter impacts your indoor air quality and makes your AC worker harder than it should to keep your home cool. Air filters are relatively inexpensive and can be swapped out in a matter of minutes, so be sure to stay on top of this simple maintenance task.
4. An Outdated Thermostat
Upgrading from an "old-school" dial thermostat to a programmable or Wi-Fi-enabled thermostat can help improve the efficiency of your AC and furnace while keeping your home plenty comfortable in the process. If you're looking to upgrade your home's thermostat or need any other HVAC repairs, contact local HVAC contractors.
