With summer just around the corner, now is the perfect time for San Ramon homeowners to ask an important question: Is your air conditioner ready for the heat? May is the ideal month to assess your cooling system and take care of any maintenance or repairs before temperatures start to soar. Waiting too long can leave you sweating—literally and financially—as HVAC companies book up fast during peak season.
Whether your AC has been dormant for months or showed signs of struggle last year, now’s the time to act. Here are the top AC repairs we commonly perform during May and how they can help you enjoy a cool, comfortable home all summer long.
1. Refrigerant Leaks and Low Refrigerant Levels
One of the most common AC problems we see in early summer is low refrigerant. Your air conditioner relies on refrigerant to remove heat from your home, and if there’s a leak, the system can’t cool effectively. Signs of a refrigerant issue include:
- Warm air blowing from vents
- Ice forming on the evaporator coils
- Hissing or bubbling sounds from the system
- Higher energy bills without increased usage
Refrigerant problems should always be handled by a licensed technician, as they require precise recharging and leak repair.
2. Electrical or Capacitor Failures
If your AC won’t turn on at all, or it starts and stops frequently (a problem known as short cycling), there could be an issue with the electrical components. Faulty capacitors, damaged relays, or corroded wiring are common culprits.
These issues are particularly common when the AC hasn’t been used for several months—moisture, dust, or rodent activity during the winter can damage electrical parts. A spring inspection can help catch these problems before they affect performance on a hot day.
3. Dirty or Clogged Air Filters and Coils
After months of inactivity, your system’s filters and coils may be covered in dust and debris. Dirty components restrict airflow, reduce cooling efficiency, and can lead to system overheating.
If your system is running but struggling to keep your home cool, replacing the filter or cleaning the evaporator and condenser coils may be all it takes to restore performance. Preventive maintenance in May can prevent costly repairs down the line.
4. Thermostat Malfunctions
Sometimes, the issue isn’t with your AC at all—it’s the thermostat. Faulty wiring, outdated models, or poor placement (such as near a window or in direct sunlight) can lead to incorrect temperature readings and poor performance. Upgrading to a programmable or smart thermostat is a great way to boost comfort and efficiency heading into the warmer months.
5. Drainage Issues
Your AC pulls humidity from the air as it cools, which drains through a condensate line. If that line is clogged or the drain pan is cracked, it can lead to water leaks, mold growth, or even system shutdowns. This is another common repair we see in San Ramon homes during the spring.
Don’t Wait Until It’s Hot—Schedule Repairs Now
The best way to avoid a midsummer breakdown is to tackle AC issues in May, before the heat peaks and before appointment slots fill up. Whether your system needs a quick fix, a tune-up, or a full diagnostic, acting now can save you money, stress, and discomfort later on.
