Rising temperatures in Spokane mean hot summer days are just around the corner. It is best to plan your air conditioner service now, before it gets too hot, to ensure everything is ready for the upcoming season. A well-functioning cooling system keeps your home comfortable and prevents unexpected breakdowns when you need it most.
At Mainstream, we recognize how crucial your air conditioner is for your family when temperatures climb. With over 20 years of experience in Spokane and the Inland Northwest, we’re here to help you stay cool this summer. Taking care of minor ac repairs and maintenance now can ensure your AC works effectively and can help avoid costly repairs in the future.
What Makes Spokane Summers Tough on AC Systems
Spokane summers aren’t just hotter—they’re lasting longer, too. What used to be a few sweltering days scattered through July now stretches into weeks of consistent heat. That extended heatwave pushes older AC units well beyond what they were designed to handle.
Many systems installed before 2010 aren’t equipped to deal with this kind of workload. They tend to run longer, use more power, and still leave parts of your home feeling warm and uncomfortable. On top of that, frequent ac repairs and rising energy bills are often signs that your cooling system is no longer up to the task.
Installing a more efficient air conditioner not only makes your home more comfortable, but it also cuts down on energy use and monthly utility costs. Plus, upgrading adds value to your home—something that matters whether you plan to stay long-term or eventually sell.
Signs Your AC Might Be Having Trouble
Before an air conditioner completely stops working, it usually gives some warning signs. Catching these signs early can prevent costlier air conditioner repairs or an inconvenient breakdown.
Warm Air Instead of Cool
If your AC is blowing warm air, something isn’t right. This issue can stem from causes like refrigerant leaks, compressor problems, or clogged filters. One common and often overlooked culprit is a failing HVAC capacitor. The capacitor powers the compressor and fan motors, and when it begins to fail, your AC may struggle to cool your home.
Unusual Noises While Running
Air conditioners should operate quietly, producing only the soft hum of air through vents. Strange sounds like humming, buzzing, or clicking indicate potential problems. A humming noise often points to a capacitor that’s failing to provide enough power, while clicking sounds may signal electrical issues. Ignoring these sounds could lead to bigger problems, including a total system failure.
Frequent On-and-Off Cycles
Short cycling, where the AC turns on and off repeatedly without completing a full cooling cycle, is inefficient and signals trouble. This issue is often linked to a failing capacitor that prevents the system from running consistently. Not only does this increase wear and tear on your AC, but it also raises your energy bills and creates uneven cooling in your home.
Rising Energy Bills
If you’ve noticed a sudden increase in your energy bills, your air conditioner may be struggling to perform efficiently. A common reason for this is a faulty capacitor, which interrupts the electrical flow that powers the system. Fixing the problem quickly can save you money and improve your AC’s performance.
Delayed Start or No Start at All
When your AC hesitates to start or doesn’t power on, the capacitor is often the issue. This small component provides the initial energy surge needed to start the compressor and fan motors. As it fails, your system may experience delays or fail completely, leaving your home uncomfortably warm.
Why the AC Capacitor Matters
Though small, the AC capacitor is a key part of your air conditioner’s functionality. It stores and releases electrical energy to power the compressor and fan motors, ensuring the system runs smoothly. Without a working capacitor, an air conditioner can’t start or maintain consistent cooling cycles.
Capacitors endure a lot of wear and tear, especially during constant use in the summer. Over time, they can weaken or fail, leading to performance issues. Knowing the importance of this component helps illustrate the value of early detection and repairs.
Signs Your HVAC Capacitor Might Be Failing
A failing capacitor often gives clear signals. Knowing what to look for can help you address problems before they cause a complete breakdown.
Visible Damage
Bulging or leaking capacitors are clear signs of trouble. A swollen or misshapen capacitor indicates it can no longer handle the electrical load, while leaks suggest internal damage. If you notice these issues during a visual inspection, it’s time to contact a professional.
Performance Problems
Trouble starting, longer cooling times, or unexpected shutdowns are common symptoms of a failing capacitor. These issues disrupt cooling and leave your home uncomfortably hot during summer’s peak temperatures.
Electrical Issues
Frequent circuit breaker trips or strange smells near the outdoor unit often point to capacitor problems. These symptoms arise when the capacitor struggles to regulate electrical flow, causing stress on the system.
Deciding Between Repair or Replacement
When faced with AC problems, deciding whether to repair or replace your unit depends on several factors:
- Age of Your AC Unit: Systems older than 10-15 years are more likely to break down repeatedly. Replacing may be a smarter choice.
- Repair Frequency: If your AC has needed multiple repairs recently, investing in a new system could save you money and reduce stress.
- Energy Efficiency: Newer AC models are significantly more energy-efficient. Upgrading can lower utility bills while improving cooling.
- Cost Comparison: Weigh the cost of repairs against the price of a new system. Frequent repairs can add up quickly, making replacement the better option.
