From small retail storefronts and restaurants along US-190 to large facilities on the I-12 corridor, Hammond businesses depend on climate control and refrigeration that does not quit. We understand the cost of downtime. Every commercial call gets priority scheduling and a stocked truck out of our Hammond shop on Covington Ridge Drive.
Our commercial division handles rooftop package units, split systems, VRF and mini-split arrays, make-up air, walk-in coolers and freezers, reach-in refrigeration, ice machines, and ongoing maintenance plans. We work with property managers, GCs, restaurant owners, school facility teams, and medical office managers across Tangipahoa, Livingston, and St. Helena Parish.

How Commercial Service Works
Priority dispatch
Commercial calls jump the queue. When a Hammond restaurant calls during a Friday lunch rush, we route the nearest tech and give the manager a direct text contact so they can plan around our arrival.
Documented service records
Every visit ends with a written work order, photos, parts list, and recommended follow-up. That documentation matters for warranty claims, health inspections, and ownership handoffs.
Honest repair-versus-replace guidance
Older rooftop units in Hammond often have one more season in them with the right repair. Sometimes a replacement is the right call. We give you the math so you can make the decision with real numbers.

Our Hammond Diagnostic Process
Every Hammond HVAC repair call starts with a structured diagnostic. We check thermostat call, transformer voltage, low-voltage signal to the air handler, blower operation, refrigerant pressures, and static pressure across the indoor coil. That sequence pins the actual fault instead of swapping parts until something works.
Repairs We Handle Most Often
- Failed run capacitors and hard-start kits
- Burned contactors and pitted relays
- Refrigerant leak repair and recharge
- Frozen evaporator coil thaw and root-cause fix
- Clogged condensate lines and float switch installs
- Failed blower motors and ECM modules
- Control board and thermostat issues
What a Hammond Tune-Up Actually Catches

Our spring AC tune-up catches weak capacitors, low refrigerant from slow leaks, clogged drains, dirty coils, and worn contactors before the July heat exposes them. The fall heating tune-up catches cracked igniters, failed flame sensors, dirty burners, and weak inducer motors before the first cold front.

Smart Thermostat Wiring in Older Hammond Homes
Many Hammond homes do not have a common (C) wire run to the thermostat. We add the C-wire properly at the air handler rather than relying on power-stealing adapters that cause smart thermostats to misbehave. Done right, your Nest or Ecobee works the way it should.

Hammond Humidity and Why It Matters
Hammond air carries 70 to 90 percent relative humidity for much of the year. That moisture load forces ACs to overcool just to dry the air, which wastes energy and makes homes feel chilly and damp. A whole-home dehumidifier paired with the right thermostat strategy fixes both problems.
