Tips for Preventing AC Emergencies Before They Start
AC preventative maintenance is one of the most effective ways to avoid unexpected breakdowns, especially during Arizona’s hottest months when your cooling system works overtime. When your air conditioner is properly maintained, it not only keeps your home cool but also helps improve energy efficiency, lower utility bills, and extend the system’s lifespan.
Extreme heat can quickly expose any weaknesses in your unit, potentially leading to a full-blown AC emergency. Fortunately, there are warning signs to watch for that can help you catch problems early. From unusual sounds and uneven temperatures to rising energy costs and odd smells, these indicators are your system’s way of asking for attention.
Here’s what you need to know to stay ahead of AC issues.
When Should You Call for AC Service?
While it’s definitely time to call a professional when your AC unit is struggling to cool your home, there are also some more subtle signs to look out for to prevent a serious AC emergency. Believe it or not, over-cooling can be a sign that your AC needs some attention.Usually, this is a sign that your thermostat is malfunctioning and is an easy fix, but it can also cause your unit to overwork and decrease its lifespan. Poor air quality is also an indicator that your unit is struggling.
If you notice a chemical smell from the AC vents, the air doesn’t seem as fresh, or your allergies are acting up, it could be time to have your unit serviced. A chemical smell could be a sign that you have a refrigerant leak in your AC unit, which could end up costing a lot to fix if it is left to run without addressing the issue.
If you happen to hear strange sounds coming from your AC unit, it’s best to contact a professional to diagnose the issue. If you hear humming, buzzing, squealing, rattling, or clanking, it’s a sign that something is wrong. Getting things like this diagnosed right away can end up saving you a lot of money and will help prevent an AC emergency.
Tips to Prevent Air Conditioner Issues
Taking care of your HVAC system doesn’t always require professional service. There are several tasks you can, and should, handle yourself as part of an AC preventative maintenance routine:
-
Change Air Filters Regularly: Replace your filters every 1–3 months to keep air flowing freely and avoid buildup of dust, allergens, and debris.
-
Keep the Outdoor Unit Clear: Remove leaves, grass, and other debris from around the condenser. A clear area improves airflow and prevents overheating.
-
Clean Vents and Registers: Blocked or dirty vents restrict airflow and reduce efficiency. Make sure they’re dust-free and unobstructed.
-
Inspect the Thermostat: Check batteries (if applicable), and ensure settings are appropriate for the season.
Having Trouble? Call a Technician
While there’s a lot homeowners can do, professional preventative maintenance is critical for in-depth care. Scheduling a seasonal tune-up, ideally in spring before the high temperatures hit, allows a trained technician to inspect refrigerant levels, test components, clean the coils, and calibrate the thermostat.
These inspections help detect problems you might not notice on your own and reduce the likelihood of costly repairs or emergency breakdowns later. Most importantly, regular maintenance ensures your system operates at peak performance all summer long. Take action now on your AC preventative maintenance to save time and money down the line.
