Why Commercial AC Repair Can't Wait
Here’s the thing about commercial cooling systems: they’re not like residential units. When a home AC breaks, it’s uncomfortable. When a commercial system fails, it can cost you thousands of dollars in lost business, spoiled inventory, and employee downtime. Santa Rosa summers can hit 90°F or higher, and in spaces like retail stores or restaurants, that heat builds up fast.
Studies show that employee productivity drops by up to 15% when indoor temperatures climb above comfortable levels. Your workers slow down, make mistakes, and can’t focus. Customers won’t stick around to shop or dine in a hot building. And if you’ve got temperature-sensitive equipment or inventory, you’re looking at potential damage that could run into serious money.
That’s why we prioritize commercial calls. Our trucks are stocked with commercial-grade parts for rooftop units, split systems, package units, and chillers. Most repairs get done on the first visit because we come prepared.
Common Commercial AC Problems We Fix
Running a business in Santa Rosa means dealing with unique climate challenges. Our Mediterranean weather brings hot, dry summers that push AC systems hard. Here’s what we see most often:
Refrigerant Leaks: This is probably the biggest culprit behind poor cooling. When refrigerant levels drop, your system works harder but cools less. You’ll notice higher energy bills, inconsistent temperatures, and frozen evaporator coils. We use leak detection equipment to find the exact problem spot, seal it properly, and recharge your system with the right refrigerant (R-410A, R-22, or R-32, depending on your unit).
Compressor Failure: The compressor is basically the heart of your AC system. When it fails, everything stops. Compressor problems often show up as strange noises, warm air from vents, or the system turning on and off repeatedly. Sometimes it’s a failed capacitor or contactor, which we can replace. Other times, you’re looking at compressor replacement, which we’ll be straight with you about.
Frozen Evaporator Coils: Sounds weird, right? Your AC freezes up when it’s hot outside? It happens more than you’d think, usually because of restricted airflow, low refrigerant, or dirty filters. We diagnose the root cause, not just the symptom, so it doesn’t keep happening.
Electrical Problems: Commercial AC systems pull a lot of power. Faulty wiring, blown fuses, tripped breakers, or bad contactors can shut everything down. Our technicians use digital multimeters and amp clamps to track down electrical issues safely and fix them right.
Thermostat Malfunctions: Modern commercial thermostats and smart controls can get finicky. Calibration issues, dead batteries, or programming errors can make your system behave strangely. We handle everything from basic thermostat replacement to advanced HVAC zone controls.
Poor Airflow: If some areas of your building feel like a sauna while others are fine, you’ve got airflow problems. Could be blocked ductwork, damaged dampers, failing blower motors, or clogged air filters. We test airflow throughout your system and fix whatever’s causing the imbalance.
Commercial AC Systems We Service
We work on every type of commercial cooling system you’ll find in Santa Rosa businesses:
Rooftop AC Units (RTUs): These are workhorses for commercial buildings. They sit on your roof, handle heating and cooling, and they’re built to run continuously. We repair and maintain all major brands, checking everything from the condenser coils to the air handlers.
Split AC Systems: Common in smaller commercial spaces, these have an outdoor condenser and indoor air handler. They’re efficient and relatively easy to maintain, but they still need expert care when things go wrong.
Package AC Units: All-in-one systems that handle both heating and cooling. Perfect for businesses with limited indoor space. We install, repair, and service package units in businesses throughout Rincon Valley, Railroad Square, and beyond.
Commercial Chillers: Larger facilities often use water-cooled or air-cooled chillers. These are complex systems that need specialized knowledge. Our technicians have the training and equipment to handle chiller repairs and maintenance.
Variable Refrigerant Flow (VRF) Systems: These high-efficiency systems let you control temperatures in different zones independently. They’re getting more popular in Santa Rosa office buildings and retail spaces. We’re factory-trained on VRF technology.
What to Expect During a Commercial AC Repair Visit
We don’t waste your time. Here’s how it actually works:
You call us (707-527-1504) or reach out online. We ask key questions about your problem, building size, and system type. If it’s an emergency, we can often have someone there within hours.
Our technician arrives in a fully stocked truck with commercial parts on board. They’re wearing a uniform, carrying proper ID, and they’ve passed background checks. First thing they do is listen to you describe the problem. You know your building better than anyone.
Then they start diagnostics. They’re using HVAC manifold gauges, temperature probes, leak detection equipment, and other specialized tools to figure out exactly what’s wrong. No guessing. They check refrigerant levels, test electrical components, inspect coils, examine ductwork, and test system performance.
Once they know what’s wrong, they explain it to you in plain English. What failed, why it failed, what it’ll take to fix it, and how much it’ll cost. Upfront pricing, no surprises. If it’s something we can fix right then, we do it. If we need to order a special part or schedule a bigger job, we’ll give you a timeline.
Most commercial AC repairs in Santa Rosa get completed the same day we show up. Our trucks carry capacitors, contactors, fan belts, blower motors, thermostatic expansion valves, and other common parts. For bigger jobs like compressor replacement or major coil work, we schedule it at a time that works for your business operations.
Preventive Maintenance: Stop Problems Before They Start
Here’s something most business owners don’t realize: about 80% of commercial AC breakdowns can be prevented with regular maintenance. We’re not trying to sell you something you don’t need. It’s just facts.
Think about it this way: would you drive your delivery truck for years without oil changes and tune-ups? Of course not. Your AC system works hard, especially during Santa Rosa summers, and it needs regular care.
Our preventive maintenance agreements include:
Coil Cleaning: Dirty condenser and evaporator coils make your system work harder and cool less effectively. We clean them thoroughly, which can cut your energy bills by 15-20%.
Refrigerant Level Checks: We verify you’ve got the right amount of refrigerant and that there are no leaks developing.
Airflow Testing: We measure airflow throughout your system to catch problems early.
Electrical Component Inspection: We check capacitors, contactors, wiring, and connections before they fail.
Filter Replacement: Using proper MERV-rated filters and changing them regularly keeps your indoor air clean and your system efficient.
Thermostat Calibration: Making sure your controls are accurate saves energy and maintains comfort.
Belt and Motor Inspection: We check fan belts for wear and test blower motors for proper operation.
System Performance Testing: We document how your system is performing so we can spot declining efficiency over time.
Every maintenance visit includes a detailed report showing what we found, what we did, and what (if anything) needs attention soon. This helps you budget for repairs instead of getting blindsided by emergencies.
Routine maintenance typically costs a fraction of what you’d pay for emergency repairs. Plus, a well-maintained system lasts 5-10 years longer than one that’s neglected.
Energy Efficiency Matters for Your Bottom Line
Energy costs are one of the biggest operating expenses for most Santa Rosa businesses. Your AC system is probably the single largest energy user in your building, especially from May through October.
When your commercial AC isn’t running efficiently, you’re throwing money away every month. Here are some numbers that might surprise you:
A system running with dirty coils can use 30% more energy than a clean one. That’s real money on your utility bill, month after month.
Refrigerant that’s just 10% low can reduce cooling capacity by 20% and increase energy use significantly.
A poorly calibrated thermostat can cause your system to run unnecessarily, wasting energy when your building doesn’t need cooling.
We do energy efficiency audits that identify where you’re losing money. Sometimes it’s as simple as adjusting your thermostat schedule or upgrading to smart controls. Other times, we might recommend newer, high-efficiency equipment that’ll pay for itself through lower utility bills.
California offers rebates and incentives for energy-efficient commercial HVAC upgrades. We’ll help you figure out what’s available and whether an upgrade makes financial sense for your business.

Frequently Asked Questions (FAQs)
How quickly can you respond to a commercial AC emergency in Santa Rosa?
For true emergencies, we aim to have a technician on-site within a few hours, sometimes faster depending on where you're located in Sonoma County and our current call schedule. We prioritize commercial emergencies because we know downtime costs you money. When you call (707-527-1504), we'll give you an honest timeframe and keep you updated. During peak summer months, we bring on additional technicians and extend hours to handle the increased demand. If you've got employees or customers suffering in the heat, we'll do everything possible to get there fast.
How much does commercial AC repair typically cost in Santa Rosa?
Honestly, it depends on what's wrong. A simple fix like replacing a capacitor or contactor might run $200-400. Refrigerant leak repair and recharge could be $500-1,500 depending on the leak location and amount of refrigerant needed. Compressor replacement on a commercial unit can run $2,000-5,000 or more, depending on the system size and type. We provide upfront pricing before we start any work, so you'll know exactly what you're paying. During the diagnostic visit, we'll identify the problem and give you a detailed quote. No hidden fees, no surprises. Sometimes we can offer repair options at different price points so you can choose what works for your budget.
Should I repair or replace my commercial AC system?
That's a big decision, and we'll help you think it through. Generally, if your system is less than 10 years old and the repair costs less than half of replacement, repair makes sense. If your system is 15+ years old, requires frequent repairs, or has major component failure (like a compressor), replacement might be smarter long-term. Newer systems are significantly more energy-efficient, which means lower utility bills that can offset the investment. We'll give you honest recommendations based on your system's age, condition, expected remaining lifespan, and your budget. We're not here to push you into a new system if your current one has good years left.
Do you work on all brands of commercial AC equipment?
Yes. We service all major commercial HVAC brands and models, including older systems and newer high-efficiency units. Our technicians receive ongoing training and have access to manufacturer technical support when needed. Whether you've got a Carrier, Trane, Lennox, York, Rheem, Goodman, or any other brand, we can diagnose and repair it. We also work on specialized equipment like VRF systems, commercial chillers, and rooftop package units.
What's included in your preventive maintenance program?
Our maintenance visits are thorough. We clean condenser and evaporator coils, check and adjust refrigerant levels, inspect and test all electrical components (capacitors, contactors, wiring), replace or clean filters, lubricate motors and bearings where applicable, check belt tension and wear, test thermostat calibration and controls, measure airflow and static pressure, inspect ductwork for leaks or damage, clean drain lines, and test overall system performance. You get a detailed report after each visit showing what we found, what we did, and any recommendations for future attention. The goal is to catch small problems before they become expensive emergencies and keep your system running efficiently.
Can you handle AC repairs for multiple locations?
Absolutely. We work with business owners and facility managers who have multiple locations throughout Sonoma County. We can coordinate maintenance and repairs across all your properties, provide consistent service, and help you manage HVAC costs across your entire operation.
