Commercial HVAC Services Across the Carolinas
Repair, replacement, preventative maintenance, and system diagnostics for commercial buildings. Technicians on call 24/7, dispatched from four Carolina branches.
Pro-Serv Facility Solutions provides commercial HVAC (heating, ventilation, and air conditioning) repair, replacement, preventative maintenance, and system diagnostics for businesses across North Carolina and South Carolina. Technicians are on call 24 hours a day for no-heat and no-cooling emergencies. Four branches cover New Bern, Raleigh, Wilmington, and Charlotte. Pro-Serv is a CFESA certified company serving restaurants, retail, offices, and commercial facilities.

What commercial HVAC services does Pro-Serv provide?
Pro-Serv Facility Solutions handles commercial HVAC repair, replacement, preventative maintenance, and system diagnostics for business properties. Technicians service rooftop units, split systems, air handlers, heat pumps, and ductwork. Work covers restaurants, retail spaces, offices, convenience stores, and multi-site facilities. Emergency repair is available 24 hours a day, seven days a week.
A commercial HVAC problem does not always start with a system that completely stops working. One office may stay warm every afternoon. Employees may keep changing the thermostat because nobody is comfortable. A restaurant may have a cold dining room and a kitchen that never cools down.
We start with what the building is doing, then work backward to the cause.
Commercial HVAC Repair
We diagnose the actual fault before replacing parts, whether the issue involves temperature, airflow, controls, refrigerant, or equipment performance.
System Replacement
Replacement starts with sizing the equipment for the building and how the space is used, not simply swapping one unit for another.
System Diagnostics
If the cause is not obvious, we track down what is changing inside the system and why the building is no longer comfortable.
Preventative Maintenance
Our preventative maintenance programs give us a chance to catch small changes before they turn into bigger problems.
Comfort and Airflow Solutions
If one room never cools down, employees keep changing the thermostat, or temperatures vary from one area to another, we can help figure out what is causing it.
Pro-Serv works with offices, retail stores, convenience stores, churches, warehouses, restaurants, and other commercial buildings. Food service is a specialty, not a limit.
What HVAC systems and brands do you service?
Pro-Serv technicians service all major commercial HVAC brands, including Carrier, Trane, Lennox, and York. System types include packaged rooftop units, split systems, air handlers, heat pumps, and ductless units. Technicians hold EPA Section 608 refrigerant certification. The age or brand of your equipment does not limit what Pro-Serv will diagnose and repair.
A packaged rooftop unit is the large heating and cooling system many business owners simply call “the unit on the roof.” These systems are common on offices, restaurants, stores, and other commercial buildings.
We also service split systems, air handlers, heat pumps, ductless units, and ductwork.
EPA Section 608 is the federal certification required for technicians who handle refrigerant. Pro-Serv is also certified by CFESA (Commercial Food Equipment Service Association).
Businesses that also need cold-side help can use our existing walk-in refrigeration service for walk-in coolers and freezers. Pro-Serv also services commercial ice machines and other refrigeration equipment.
How fast can you get a technician to my building?
Pro-Serv dispatches from four branches in New Bern, Raleigh, Wilmington, and Charlotte, which keeps technicians close to most Carolina markets. Emergency calls are answered 24 hours a day, seven days a week, and same-day service is available for no-heat and no-cooling failures. Standard service is scheduled around your operating hours.
Where your building is located, technician availability, and the type of problem all affect dispatch. We do not promise an exact response time that has not been confirmed.
New Bern
Our New Bern service team supports Eastern North Carolina and surrounding areas.
Raleigh
Commercial HVAC service for Raleigh and businesses across the Triangle.
Wilmington
Serving Wilmington businesses and nearby coastal areas.
Charlotte
Serving Charlotte and the surrounding commercial market.
Preventative maintenance customers receive priority scheduling. Standard service can also be planned around operating hours, so a restaurant does not need roof work during dinner service or a retailer during its busiest period.
Professional. Reliable. Hard Working. Team Driven. Results Matter.
What are the most common commercial HVAC failures?
The most common commercial HVAC failures are compressor faults, refrigerant leaks, blower motor failures, economizer and damper problems, control board and thermostat faults, and clogged condensate drains. Most begin as small performance drops rather than total shutdowns. Catching them early is why scheduled maintenance costs less than emergency repair.
Most businesses notice the symptom before they know the part causing it.
The system runs all day but never gets cold
Low refrigerant or a compressor problem could be keeping it from cooling properly.
The airflow is weaker than usual
A worn belt or blower motor problem may be cutting down the amount of air moving through the building.
The heating bill suddenly goes up
An economizer or damper problem could be letting too much outside air into the building.
One room is always hotter or colder than the rest
The thermostat, sensor, or controls for that area may not be working the way they should.
A water stain shows up on a ceiling tile
A clogged condensate drain may be causing water to back up.
The unit starts rattling or grinding
A motor or another moving part may be starting to wear out.
These changes are worth checking while the equipment is still running. The maintenance section below explains what technicians look for before a small performance issue becomes a larger service call.
Why do restaurants and food-service buildings need HVAC handled differently?
Food-service buildings move far more air than a typical office, because kitchen exhaust hoods pull conditioned air out continuously. When makeup air does not match that exhaust, the building runs negative, doors stick, and hood capture drops. Pro-Serv services the hood, the makeup air unit, and the HVAC system together.
A commercial kitchen hood removes hot air, smoke, grease, and conditioned air from the building. That air has to be replaced with makeup air. Once a hood moves more than 400 CFM, a measure of airflow, building codes require replacement air. When that air does not keep up, the building can fall out of balance and the hood may not capture smoke and grease as well as it should.
You may notice things like:
In a restaurant, HVAC, exhaust, makeup air, refrigeration, and cooking equipment all affect one another. Pro-Serv already works on commercial hood and exhaust cleaning, commercial kitchen equipment repair, refrigeration, and HVAC, so one team can look at the building as a whole instead of treating the rooftop unit as the only issue.
What does a preventative maintenance program include?
A Pro-Serv preventative maintenance program covers scheduled inspections, coil and filter cleaning, refrigerant and airflow checks, belt and motor service, control calibration, and a written condition report. Visits are scheduled seasonally or quarterly based on your equipment and run hours. Programs can cover HVAC alone or the full facility.
A maintenance visit may include:
- Cleaning coils and checking filters
- Checking refrigerant levels and system pressure
- Making sure air is moving the way it should
- Looking over belts and motors for wear
- Checking electrical connections
- Testing the thermostat and system controls
- Making sure condensate is draining properly
- Documenting the condition of the equipment
The written report creates a service history for each unit, so decisions do not have to rely on someone simply saying, “the unit is old.” It shows what has changed, how often the equipment has needed repair, and whether the same problems keep returning.
That gives facilities managers something concrete to use when planning future repairs or replacement. Documented maintenance may also be required by equipment manufacturers to maintain warranty coverage.
Programs can cover HVAC alone or connect with Pro-Serv’s broader preventative maintenance services.
What does commercial HVAC service cost?
Commercial HVAC cost depends on system size, equipment age, access, and whether the work is a repair, a maintenance program, or a replacement. Pro-Serv quotes after a technician has diagnosed the system, not over the phone. Maintenance programs are priced per building, based on equipment count and visit frequency.
For repairs, the cost comes down to what is wrong, what parts are needed, and how long the repair takes. Maintenance is priced differently because it depends on the equipment in the building and how often it needs to be serviced.
Replacement is a bigger decision. The new system has to fit the building and be sized correctly, not just match the old unit.
That is why a commercial HVAC quote cannot be accurate from a phone description alone. Two buildings can have the same complaint and completely different causes.

Should you repair or replace a commercial HVAC system?
Repair usually makes sense when the system is under twelve to fifteen years old and the repair costs less than a third of replacement. Replacement makes sense when the compressor has failed, the unit uses a phased-out refrigerant, or repair costs are stacking up year over year. Pro-Serv gives you both numbers before you decide.
Ask:
- How old is the system?
- How does the repair cost compare with replacement?
- What refrigerant does the unit use?
- How many repairs has it needed in the last two years?
A newer system with one isolated problem may still have plenty of useful life left. An older unit with repeat compressor, refrigerant, electrical, or control problems may be harder to justify.
Refrigerant matters too. Phase-outs are making some older refrigerants more expensive and harder to source.
The goal is not to replace equipment simply because it is old. Pro-Serv gives you the repair number and the replacement number before you decide.

Frequently Asked Questions
Do you service commercial HVAC outside of restaurants?
Yes. Pro-Serv services commercial HVAC for offices, retail spaces, convenience stores, churches, warehouses, and multi-site facilities across the Carolinas. Food service is a specialty, not a limit. Any commercial building with a rooftop unit, split system, or heat pump can be serviced by a Pro-Serv technician.
Do you offer 24-hour emergency HVAC service?
Yes. Pro-Serv technicians are on call 24 hours a day, seven days a week for commercial HVAC emergencies, including no-heat and no-cooling failures. Emergency calls are dispatched from the nearest of four Carolina branches. Call (910) 650-3721 to reach a technician.
What HVAC brands do your technicians work on?
Pro-Serv technicians service all major commercial brands, including Carrier, Trane, Lennox, and York. Both packaged rooftop units and split systems are covered, along with air handlers, heat pumps, and ductless units. Technicians hold EPA Section 608 refrigerant certification.
How often should a commercial HVAC system be serviced?
Most commercial HVAC systems should be professionally serviced at least twice a year, before the cooling season and before the heating season. Buildings with heavy run hours, such as restaurants and 24-hour operations, are usually better served quarterly. Equipment count and run hours set the right schedule.
Why does my restaurant feel hot even when the AC is running?
A restaurant that stays hot with the air conditioning running is often out of air balance. Kitchen exhaust hoods pull conditioned air out faster than the makeup air system replaces it, so the system runs constantly without catching up. The fix is balancing exhaust and makeup air, not just the rooftop unit.
Can you handle HVAC for all of our locations?
Yes. Pro-Serv operates four branches in New Bern, Raleigh, Wilmington, and Charlotte, covering North Carolina and South Carolina. Multi-location businesses can run every site through a single account and one service number, with consistent reporting across locations.
Do you offer commercial HVAC maintenance contracts?
Yes. Pro-Serv builds preventative maintenance programs covering scheduled inspections, cleaning, refrigerant and airflow checks, and a written condition report after each visit. Programs can cover HVAC alone or extend across refrigeration, cooking equipment, hood systems, and plumbing.
Is it worth repairing an older commercial HVAC unit?
It depends on age, repair cost, and refrigerant type. A system under twelve to fifteen years old with a repair costing less than a third of replacement is usually worth repairing. Failed compressors, phased-out refrigerants, and repeat repairs point toward replacement. Pro-Serv provides both numbers.
