24/7 Commercial HVAC Repair: Rooftop Units, Commercial AC & Heating
A failed rooftop unit at 6 a.m. doesn’t wait for business hours. AVS offers commercial HVAC repair around the clock, with nights, weekends and holidays at standard rates, because we don’t charge overtime fees.
What we repair:
- Rooftop units (RTUs) and packaged units: compressors, fans, controls and the rest of the system.
- Commercial AC repair: commercial split systems and rooftop cooling. No cooling, weak airflow, frozen coils and refrigerant issues.
- Commercial heating repair: commercial furnaces and heat pumps. No heat, short cycling and failed ignition.
Every service call starts with a diagnosis and a written price before work begins. If the repair doesn’t make economic sense, we’ll tell you, and quote the replacement side by side.
Commercial Furnace Installation & Heating Replacement
Heating equipment that runs hard every winter eventually loses efficiency, breaks down more often, and becomes a liability. AVS handles commercial furnace installation and commercial heating replacement, plus commercial heat pumps and packaged heating systems, sized to your building’s actual load.
Replacement makes sense when repairs exceed half the cost of a new unit, when parts are obsolete, or when the system is old enough that its efficiency is costing you every month in energy bills. Installation can be scheduled around your operations, with no extra charge for nights and weekends.
Every commercial heating project starts with a free written estimate: site walkthrough, load assessment, equipment options at different efficiency levels, and one written price. Financing is available through Wells Fargo, including 0% APR up to 18 months on select units and zero-down plans (subject to lender approval).
Commercial AC Installation & Replacement
Commercial cooling has one unforgiving season: summer, when your building needs it most and your old system is most likely to fail. If your rooftop units or commercial split systems are limping through another season, plan the commercial HVAC replacement before the next heat wave.
We install and replace commercial air conditioning systems, including rooftop packaged units and split systems, with proper sizing and airflow checks. New equipment brings lower energy costs, quieter operation and a new manufacturer’s warranty.
Like every project: free written estimate, written price before work starts, and installation scheduled around your operations, with no extra charge after hours.
Preventive Maintenance for Businesses
Scheduled maintenance catches small problems before they become emergency calls. Spring and fall inspections cover coils, refrigerant levels, electrical connections, belts, drains and controls, so your equipment is ready for each season.
Maintenance for commercial buildings is priced per building and per system. Call for a quote, and we’ll walk your property and give you a written number.

What Customers Say About AVS Commercial HVAC
“Had a complex issue with a commercial walk-in fridge. They were able to diagnose the issue and quickly make repairs in a fraction of the time I was quoted from other vendors to even just come and look at our system. Great work.”
“It was very nice working with AVS. They arrived in the estimated time window, and Anil diagnosed the AC problem right away at our commercial property. AVS had the AC motor replaced and everything working again quickly. They were very friendly and professional. Would recommend!”
