Why Stout’s Heating & Air Conditioning is the Right Choice?
-
We are a fully licensed HVAC contractor in California — our technicians are EPA-certified refrigerant handlers. We follow all safety and environmental regulations during repair and refrigerant handling (per the U.S. Clean Air Act, Section 608).
-
We use commercial-grade tools and equipment: manifold gauges, refrigerant recovery machines, leak detectors, multimeters, coil-cleaning gear, and more.
-
We work with all major refrigerants (like R-410A, newer compliant types), and replace capacitors, blower motors, condensers, coils, TXVs (thermostatic expansion valves), ducts, and drain lines when needed.
-
We follow proper processes: diagnostics, pressure testing, refrigerant recharge, electrical testing, coil cleaning, airflow balancing, and safety checks. Often that means we fix the real issue — not just patch symptoms.
-
If you have older or struggling systems, we also offer AC maintenance, tune-ups, indoor-air quality checks, duct sealing, and energy-efficiency upgrades.
Because we know businesses in Cotati can’t afford long downtime, we aim for a fast turnaround, reliable repairs, and transparent pricing.
What Types of Commercial AC Problems We Fix?
Here are common issues we see — and how we address them:
-
AC is on but blowing warm air → Could be a failed compressor, refrigerant leak, or bad capacitor. We inspect and test refrigerant levels, pressure, and electrical components, then replace faulty parts.
-
Poor or weak airflow from vents → Often due to clogged air filters, duct leaks, or failing blower motors. We replace filters, inspect ducts, and fix or replace motors if needed.
-
Strange noises — rattling, grinding, buzzing, banging → Might be debris, loose parts, or worn mechanical components. We diagnose, tighten/replace parts, and test to ensure safe, quiet operation.
-
Frequent on–off cycling (short cycling) → Could be thermostat issues, sensor problems, refrigerant imbalance, or electrical faults. We check thermostats, sensors, and system pressure to correct the root cause.
-
Water leaks or condensation around units → Usually from clogged drain lines, broken drain pans or condensate pumps, or frozen coils. We clean or repair drain lines/pans, check refrigerant and airflow, and restore proper drainage.
-
High electricity bills, uneven cooling, humidity problems, bad indoor air quality → We can perform energy efficiency inspections, duct sealing, indoor-air quality services, and ventilation improvements to address root causes.

Common Commercial AC Problems — And Why They Happen
Here’s what often goes wrong in business HVAC systems (and why):
-
Refrigerant leaks — over time, small leaks or corrosion reduce refrigerant levels. That lowers cooling power and can freeze coils or damage the compressor.
-
Clogged or dirty components — dust, dirt, and debris build up in filters, coils, or ducts. That restricts airflow, reduces efficiency, and raises energy bills.
-
Mechanical wear & tear — blowers, motors, capacitors, compressors — constantly working, especially in commercial use, tend to wear out faster.
-
Ductwork or ventilation issues — leaks, poor sealing, or improper design cause uneven cooling or hot/cold spots across your building.
-
Electrical or thermostat failures — faulty wiring, sensors, or thermostat issues can lead to short-cycling, inconsistent temps, or total system failure.
Because commercial systems often run longer and serve larger spaces than residential ones, problems can escalate fast. That’s why early detection and regular maintenance matter.
Save Money & Avoid Downtime — The Value of Preventive Maintenance
Most business owners dread unexpected system failure — especially on hot summer days when customers or staff expect comfort. Regular maintenance helps:
-
Extend system lifespan (many commercial HVAC systems, when well-maintained, can run 15–20 years)
-
Catch small issues before they become big, expensive breakdowns
-
Keep your energy bills down by maintaining airflow and refrigerant efficiency
-
Ensure good air quality (clean filters, ducts, and ventilation reduce dust, allergens, mold risk — especially important if you store inventory or have many employees)
We can set up a custom maintenance program for your building — semi-annual or quarterly, depending on usage and size.

Frequently Asked Questions (FAQs)
How often should I have my commercial AC system serviced?
We recommend at least twice a year once in the spring (before summer cooling) and once in the fall (before winter heating, if you have HVAC heating). Regular tune-ups catch small problems early and keep your system running efficiently.
My AC is running but delivers warm air. Is this an emergency?
Yes, warm air often means refrigerant leak, compressor failure, or electrical issue. These problems can damage the compressor if ignored. Call a licensed commercial HVAC technician (like us) right away for diagnostics and possible refrigerant recharge or component replacement.
Can I just replace the air filter myself to fix poor airflow?
Replacing the filter is a good first step, but if the problem persists, the issue might be deeper (duct leaks, blower motor failure, dirty coils, etc.). It’s worth getting a pro to inspect the whole system periodically.
My building has a rooftop HVAC unit. Do you service rooftop systems?
Yes. We service and repair rooftop units, split systems, multi-split systems, and standard commercial HVAC setups. We’re equipped and trained for rooftop safety, proper refrigerant handling, and system balancing.
Do you offer emergency or after-hours AC repair?
Yes. We understand AC problems don’t always strike at convenient times. We offer emergency repair service for many commercial clients to minimize downtime for your business.
How long does a typical commercial AC repair take?
It depends on the issue. Simple repairs, like replacing a capacitor or cleaning coils, can take a few hours. More complex problems (compressor or refrigerant leak repair) may take longer, especially if parts are required. After inspection, we’ll give you a clear estimate.
How can I make sure my AC lasts longer and stays efficient?
Keep air filters clean (check monthly or every 1–3 months), schedule regular maintenance twice a year, seal ducts if needed, and consider upgrades when your system is older than 10–15 years. These steps help maintain airflow, refrigerant balance, and indoor air quality.
