Common Commercial AC Problems We Fix
Most AC issues come from a handful of causes. Here are the problems we fix most often — and how they affect businesses in Sonoma.
- Compressor Problems
A failing compressor often leads to warm air blowing through vents or the system constantly running without cooling. This is one of the most serious AC issues, and it needs fast attention to avoid a full shut-down.
- Dirty Coils or Clogged Filters
Dust, debris, and grease buildup restrict airflow and cause weak cooling, hot spots, and high energy bills. In busy or high-traffic commercial environments, this happens more often than people expect.
- Electrical Failures
Loose wiring, burnt capacitors, worn contactors, or malfunctioning sensors can cause the AC to shut off randomly, blow warm air, or stop responding to the thermostat.
- Fan and Blower Motor Issues
When the blower motor slows down or fails, airflow drops dramatically. You might feel weak airflow in some areas or no air at all.
- Refrigerant Leaks
Low refrigerant doesn’t just weaken cooling — it causes coil icing, compressor stress, and sudden shutdowns. Leaks must be found and repaired properly.
- Drainage Problems
Clogged drain lines cause water leaks around indoor units or moisture issues inside commercial spaces.
- Poor System Design or Old Equipment
Many older buildings around Sonoma Plaza, wineries, or historical structures weren’t designed with modern HVAC loads in mind. This can cause uneven cooling, constant cycling, or oversized/undersized units.
Why Commercial AC Maintenance Is Essential
A lot of business owners skip maintenance until something breaks. But here’s what usually happens when maintenance is ignored:
- Higher cooling costs
- Weak airflow and uneven temperatures
- More breakdowns at the worst possible times
- Shorter equipment lifespan
- Lower indoor air quality
- Safety risks from worn electrical parts or refrigerant issues
A maintenance visit covers the essentials:
- Filter replacement
- Coil cleaning
- Refrigerant level testing
- Electrical inspections
- Airflow testing
- Belt and motor checks
- Thermostat calibration
Catching small problems early protects you from big, expensive issues later.
What Makes Stout’s Heating & AC Stand Out
Here’s what we do better than many competitor pages or contractors:
We specialize in commercial HVAC
Commercial systems require different tools, training, and experience than residential systems. We know how to handle rooftop units, large condenser units, multi-zone systems, and heavy-duty motors.
We’re honest about repair vs. replacement
If your system can be repaired safely and reliably, we’ll repair it. If replacement is the smarter choice, we’ll explain why and show the long-term cost difference.
We use advanced diagnostic tools
We bring the right equipment to every job:
- Refrigerant gauges
- Multimeters
- Thermal imaging cameras
- Leak detection tools
- Coil cleaning tools
- Vacuum pumps
This ensures accurate diagnosis and long-lasting repairs.
We know Sonoma buildings
Older commercial buildings near the Plaza or around local wineries often have unique duct setups or aging systems. Newer buildings near the Arnold Drive corridor have different needs. We work with all of them.

Frequently Asked Questions (FAQs)
How often should commercial AC systems be maintained?
Twice a year is ideal — once before summer and once before winter. For restaurants, wineries, or high-use buildings, quarterly maintenance is even better.
Why are some rooms cold while others stay warm?
This usually points to airflow issues, duct problems, dirty coils, or a system that wasn’t sized correctly. We run airflow testing to pinpoint the cause.
Is it better to repair or replace an older AC unit?
If your system is 12 to 15 years old, needs repeated repairs, or uses outdated parts, replacement may save money long-term. We’ll give you honest recommendations based on your actual system.
What causes refrigerant leaks in commercial AC units?
Wear and tear, vibration, corrosion, or accidental damage. Once refrigerant levels drop, cooling weakens, coils freeze, and the compressor can fail.
Do you offer emergency repair service?
Yes. If your business is heating up and you need urgent commercial AC repair, we can respond quickly and get your cooling back.
How long does a typical commercial AC repair take?
Smaller fixes can be done the same day. Larger repairs — like replacing motors, compressors, or coils — may take longer depending on parts availability.
Do you offer maintenance plans?
Yes. Many local businesses in Sonoma use our preventive maintenance plans to reduce downtime and avoid surprise breakdowns.
