Central Texas is no stranger to hot, humid summers that push air conditioners to their limits. Whether you live in Kyle, Buda, South Austin, Onion Creek or San Marcos, your AC is a lifeline during those blistering summer months. But how often should you schedule AC service to keep it running smoothly?
If you’re asking this question, you’re not alone. Many homeowners and business owners overlook regular air conditioning maintenance until something breaks down. Unfortunately, by that time, repairs can be costly—and often avoidable.
Here’s a detailed breakdown of how often you should schedule AC service in Central Texas, what it includes and why it matters more than you might think.
Why Regular AC Maintenance Is Non-Negotiable in Central Texas
In a climate like Central Texas, your air conditioner works overtime, especially from late spring through early fall. High temperatures and prolonged cooling cycles result in increased wear and tear on your system. Skipping maintenance could shorten the life of your unit and lead to inefficient performance or sudden breakdowns when you need it the most.
Regular AC service helps:
- Maximise energy efficiency
- Prevent unexpected breakdowns
- Improve indoor air quality
- Extend the life of your AC system
- Lower your monthly energy bills
How Often Should You Service Your Air Conditioner?
The golden rule for most homeowners is to schedule AC maintenance at least once per year, preferably in the spring before peak usage begins.
However, there are a few factors that might change that recommendation:
1. Older AC Units: if your AC unit is over a decade old, it’s working harder than newer models to cool your home. Scheduling two maintenance checkups per year—one in the spring and another in the fall—can help you stay ahead of wear and tear.
2. Commercial Properties: Businesses often have larger or more complex HVAC systems, especially in restaurants, medical offices or multi-tenant spaces. In these cases, scheduling quarterly service is recommended to ensure optimal performance and avoid downtime.
3. Heavy Usage Households: Do you run your air conditioner 24/7 during the summer? Have pets or people with allergies at home? These factors can accelerate wear and decrease air quality, making it wise to schedule service every six months.
4. Newer AC Units: Even if you just had a new unit installed, don’t skip out on annual maintenance. Most HVAC manufacturers require regular servicing to keep warranties valid.
What Happens During a Typical AC Service Visit?
A professional HVAC contractor in Central Texas will perform a thorough tune-up that includes:
- Checking refrigerant levels and looking for leaks
- Cleaning the condenser and evaporator coils
- Inspecting electrical connections and controls
- Testing thermostat calibration
- Flushing the condensate drain line
- Replacing or cleaning air filters
- Checking and lubricating moving parts
- Evaluating system performance and airflow
This kind of proactive care not only helps your unit perform at its best but also gives your technician a chance to catch small issues before they become major problems.
Warning Signs That You Need Immediate AC Service
While scheduled maintenance is important, there are times when you shouldn’t wait. If you notice any of the following issues, it’s time to call an HVAC technician:
- Strange noises (buzzing, grinding or squealing)
- Weak airflow or hot spots in your home
- A sudden spike in energy bills
- AC unit short cycling (turning on and off quickly)
- Unpleasant odours coming from vents
- Excessive moisture or leaks around the unit
Don’t wait for complete system failure—these signs typically indicate a problem that can get worse if left untreated.
DIY Maintenance Tips Between Service Calls
Although professional servicing is essential, there are a few things you can do yourself to keep your AC running smoothly:
- Change Air Filters Regularly – Replace filters every 1-3 months, depending on usage and household conditions.
- Keep Outdoor Units Clear – Trim plants and remove debris around your condenser.
- Check Thermostat Settings – Use programmable thermostats to reduce unnecessary strain on the system.
- Clean Vents and Registers – Dust buildup can restrict airflow and lower efficiency.
Simple steps like these can help stretch the time between professional tune-ups and keep your AC system humming.
The Cost of Skipping Maintenance
It might seem like you’re saving money by avoiding routine AC service, but the long-term costs are often much higher. Consider this:
- A neglected system can lose up to 5% efficiency per year
- Minor issues can snowball into major repairs or full replacements
- Emergency repair calls are often more expensive
- A poorly maintained unit has a shorter lifespan, sometimes by several years
The price of a routine tune-up is minimal compared to the cost of a full AC replacement or emergency repair during a 100-degree weekend in July.
Best Time to Schedule AC Maintenance in Central Texas
The best time to schedule air conditioning maintenance is early spring—ideally March or April—before your AC is in constant use. HVAC contractors tend to get booked quickly as the weather heats up, so early scheduling ensures you’re ready for summer.
For dual service (spring and fall), aim for:
- Spring Service: March to May
- Fall Service: September to November
Choosing the Right HVAC Contractor
Not all HVAC companies are created equal. When scheduling AC service in Central Texas, look for a contractor with:
- Positive local reviews
- Proper licensing and insurance
- Transparent pricing
- Emergency repair options
- Experience with both residential and commercial systems
Don’t be afraid to ask about maintenance plans, too. Many HVAC companies offer affordable annual service agreements that include regular checkups and priority scheduling.
Final Thoughts
In Central Texas, regular AC maintenance isn’t just a good idea—it’s essential. Scheduling professional AC service at least once a year helps prevent costly repairs, keeps your energy bills in check and ensures your home stays cool when it matters most.
Whether you’re in Kyle, Buda, Onion Creek, San Marcos or South Austin, staying on top of HVAC care can save you money and headaches in the long run.
