Commercial HVAC Preventative Maintenance | High Point, NC

Q: What is included in a commercial HVAC preventative maintenance visit?

A standard SBS-NC preventative maintenance visit includes filter replacement, condenser and evaporator coil cleaning, belt and bearing inspection, refrigerant pressure and superheat checks, electrical connection and amp draw testing, condensate drain clearing, control and thermostat verification, and a written report of findings for each unit.

Q: Does SBS-NC supply air filters?

Yes. SBS-NC is also a filter vendor, so the correct sizes and MERV ratings for your equipment are stocked and changed on schedule without a separate purchase order.

Q: Can SBS-NC maintain multiple locations in different states?

Yes. SBS-NC self-performs preventative maintenance across North Carolina, South Carolina, Georgia, Florida, Alabama, and Tennessee, giving multi-site customers one point of contact, one maintenance standard, and consistent reporting for every location.

The short answer

A commercial HVAC preventative maintenance program is a scheduled service agreement in which a contractor inspects, cleans, and tunes your equipment on a fixed calendar rather than waiting for it to fail. SBS-NC, LLC has self-performed PM for commercial facilities in Greensboro, Winston-Salem, and High Point, NC — the Piedmont Triad — and across the Southeast since 1992. A typical program includes two to twelve visits per year, filter changes, coil cleaning, electrical and refrigerant checks, per-unit written reports, and 24/7 priority dispatch when something does go wrong. Programs are sized to the building — semi-annual, quarterly, or monthly — and cover rooftop units, split systems, chillers, boilers, cooling towers, VRF, and building controls.

Why PM Pays

Planned work is cheaper than emergency work.

A failed compressor on the hottest Friday of the year costs more than the year of maintenance that would have caught it. That is the entire argument, and it holds up.

Lower energy cost

Dirty coils and loaded filters force equipment to run longer to hit setpoint. Clean systems draw less.

Longer equipment life

Belts, bearings, and contactors get replaced on schedule instead of taking a compressor with them.

Less downtime

Problems surface during a scheduled visit, not during business hours with customers in the building.

Budget you can defend

Documented equipment history turns capital replacement requests into evidence instead of guesses.

Scope of Work

What's in a maintenance visit.

Every technician works from the same checklist, and every visit produces a written report per unit.

Filter replacement

Correct size and MERV rating for each unit — we stock them, so nothing waits on a PO.

Coil cleaning

Condenser and evaporator coils cleaned so the system isn't fighting its own airflow.

Refrigerant check

Pressures, superheat, and subcooling verified; leaks found before the charge is gone.

Electrical inspection

Connections tightened, amp draws recorded, contactors and capacitors tested under load.

Belts & bearings

Tension, wear, and alignment checked; failing parts flagged or replaced on the spot.

Condensate & drains

Pans and lines cleared to prevent overflow, ceiling damage, and microbial growth.

Controls & thermostats

Setpoints, schedules, sensors, and BAS integration verified against how the space is used.

Economizer & dampers

Linkages and actuators exercised so free cooling actually works when it should.

Heat exchanger & burners

Combustion components inspected ahead of heating season for safety and efficiency.

Written report

Per-unit findings, photos where relevant, and recommendations with quoted repairs.

Common Questions

Preventative maintenance FAQ.

What is included in a commercial HVAC preventative maintenance visit?

A standard SBS-NC visit includes filter replacement, condenser and evaporator coil cleaning, belt and bearing inspection, refrigerant pressure and superheat checks, electrical connection and amp-draw testing, condensate drain clearing, control and thermostat verification, and a written report of findings for each unit.

How often should commercial HVAC equipment be maintained?

Most commercial rooftop units and split systems should be serviced at least twice a year — before cooling season and before heating season. High-runtime equipment, restaurants, manufacturing plants, and buildings with heavy filtration loads are better served quarterly or monthly.

Does preventative maintenance actually save money?

Yes. Clean coils and fresh filters reduce the energy a system uses to reach setpoint, and scheduled inspection catches failing capacitors, contactors, bearings, and refrigerant leaks before they cascade into compressor failure. Planned maintenance is consistently cheaper than emergency repair and premature replacement.

Does SBS-NC supply air filters?

Yes. We are also a filter vendor, so the correct sizes and MERV ratings for your equipment are stocked and changed on schedule without a separate purchase order.

Can SBS-NC maintain multiple locations in different states?

Yes. We self-perform preventative maintenance across North Carolina, South Carolina, Georgia, Florida, Alabama, and Tennessee — one point of contact, one maintenance standard, and consistent reporting for every location.

Do maintenance contract customers get priority service?

Yes. Contract customers receive 24/7 emergency response and front-of-line dispatch when equipment goes down, plus documented equipment history that supports capital planning.
