There’s nothing worse than walking into your home or business on a 90-degree day — and realizing your air conditioner isn’t working right. Whether it’s blowing warm air, cycling constantly, or running up your energy bill, AC issues are all too common in Maryland’s humid summers.
At Funk Electrical, we know how to keep cooling systems running smoothly when it matters most. Here are the most common reasons your air conditioner might be struggling — and what you can do about it.
1. Dirty Coils or Clogged Filters
Airflow is everything. When your filter is clogged or your evaporator coil is dirty, your system has to work twice as hard to push cool air through. Not only does this strain the unit, but it also increases your electric bill. We recommend checking filters monthly and scheduling professional coil cleanings once a year.
2. Refrigerant Leaks or Low Levels
If your AC is blowing warm air, low refrigerant may be the cause. This isn’t a DIY fix — leaks can only be safely handled by a licensed technician. We’ll find the leak, repair it, and recharge the system so it cools efficiently again.
3. Aging or Undersized Equipment
Air conditioners typically last 10–15 years. If yours is older, inefficient, or undersized for your home or building, it might never reach your set temperature. We offer system evaluations and can recommend energy-efficient models that fit your space and budget.
4. Thermostat or Electrical Issues
Sometimes the problem isn’t with the AC itself — it’s with the thermostat or electrical connection. Our technicians test and recalibrate thermostats, inspect wiring, and ensure your system’s electrical components are properly functioning.
5. Routine Maintenance Matters
Annual maintenance visits help prevent 80% of common AC breakdowns. From cleaning coils to tightening connections, we make sure your system is tuned up before summer heat peaks.
Don’t sweat through another Maryland summer. Schedule your AC tune-up or repair with Funk Electrical today, and let’s keep your home or business comfortably cool all season long.
