A malfunctioning air conditioner can quickly turn a pleasant day into an uncomfortable one. When your AC system shows signs of trouble, timely and effective repair is crucial. Our team specializes in diagnosing and fixing a wide range of air conditioning issues for residents and businesses in Ballwin.
Common problems we address include:

- Leaking Water or Refrigerant: Water leaks often point to drain line clogs, while refrigerant leaks are a more serious issue affecting cooling performance and system health.
- Frequent Cycling: If your AC unit constantly turns on and off, it could signal a system that's too large, electrical issues, or a clogged air filter restricting airflow.
- Uneven Cooling: Hot and cold spots in your property might indicate ductwork problems, airflow issues, or a struggling system unable to distribute cool air effectively.

New AC Installation & Replacement in Ballwin
Deciding whether to repair or replace your existing air conditioning system is a significant decision. If your AC unit is old (typically over 10-15 years), requires frequent, costly repairs, or your energy bills are steadily climbing, a new AC Installation or AC Replacement could be the most cost-effective long-term solution for your Ballwin property. Installing a new, energy-efficient system offers numerous benefits, including improved comfort, enhanced reliability, quieter operation, and significant savings on your monthly energy bills.
Our installation process begins with a comprehensive assessment of your property's size, layout, insulation, and specific cooling needs. This allows us to recommend the appropriately sized system to ensure optimal performance and efficiency – an undersized unit won't cool effectively, while an oversized one will cycle too often, leading to wear and tear and inefficient operation.
We work with various types of air conditioning systems suitable for Ballwin properties, including central air conditioning systems and ductless mini-split systems, which are ideal for specific zones or properties without existing ductwork. We feature reliable Goodman and Daikin systems, known for their quality and efficiency, offering impressive warranties, including limited lifetime warranties on certain components like compressors and heat exchangers.
We also provide guidance on understanding energy efficiency ratings like SEER2, helping you choose a system that aligns with your budget and long-term energy savings goals. Exploring Financing options can also help make the investment in a new, comfortable system more manageable.

- Enhances Comfort: A well-maintained system provides consistent and even cooling throughout your property.
- Maintains Warranty: Many manufacturers require annual maintenance to keep warranty coverage valid.
- Improves Air Quality: Cleaning or replacing air filters is a standard part of maintenance, contributing to healthier indoor air.

Frequently Asked Questions About AC in Ballwin
How much does AC repair cost in Ballwin?
The cost of AC repair varies greatly depending on the specific problem, the type and age of your system, and the parts required. Simple fixes like a clogged drain line or a faulty capacitor are typically less expensive than complex issues like a compressor failure or a refrigerant leak requiring detection and repair. A diagnostic visit is needed to accurately determine the cost of the repair.
Should I repair or replace my old AC system?
This is a common question. Generally, if your AC unit is over 10-15 years old, requires frequent repairs, or is significantly less efficient than modern systems (low SEER rating), replacement often makes more sense financially in the long run. A good guideline is the "rule of 5000": multiply the cost of the repair by the age of the unit. If the result is over $5000, replacement is likely the better option. However, our technicians can assess your specific situation and provide personalized recommendations based on the system's condition, repair cost, and potential energy savings from a new unit.
How often should I have my AC system maintained?
Most manufacturers and HVAC professionals recommend annual maintenance for your air conditioning system. Scheduling a tune-up in the spring before the cooling season begins ensures your system is clean, running efficiently, and less likely to break down during the hottest months. For heat pumps, a second check-up in the fall before the heating season is also recommended.
What are common reasons my AC isn't cooling effectively?
Several factors can cause poor cooling:
- A dirty air filter restricting airflow.
- Frozen evaporator coils due to low refrigerant or poor airflow.
- Refrigerant leaks.
- A malfunctioning capacitor or motor.
- Issues with the thermostat.
- Problems with the outdoor condenser unit.
Identifying the exact cause requires professional inspection.
