Repair & 24/7 Emergency Service

When a system goes down, the answer you need first is what is actually wrong. We diagnose electrically and mechanically before we quote parts: refrigerant, compressors, boards, contactors, capacitors, sensors, airflow. Then we tell you straight whether repair or replacement is the better spend on that unit.

Technician diagnosing HVAC electrical controls
What the job includes
  • /24/7 emergency dispatch
  • /Full electrical & mechanical diagnosis
  • /EPA 608 certified refrigerant work
  • /Compressor & board replacement
  • /Leak search and repair
  • /Written findings, not guesses
07

Preventive Maintenance

Maintenance is where HVAC money is either saved or wasted. Most of the emergency calls we run trace back to a dirty coil, a loose lug or a filter nobody changed. We build a maintenance interval around your equipment and your season, take real readings every visit, and hand you the numbers so you can see the system trending before it fails.

Technicians performing documented preventive maintenance
What the job includes
  • /Filter and coil service
  • /Amp draw and voltage readings
  • /Superheat / subcool verification
  • /Belt, bearing and drive checks
  • /Condensate and drain line clearing
  • /Documented readings each visit

New Installs & System Replacements

A replacement is only as good as the load calculation and the airflow behind it. We size to the actual building, not to whatever came off the roof, then handle equipment procurement, rigging, permits and start-up. You get a written scope before anything is ordered, and the equipment we install is what the scope says.

New equipment set during a full system replacement
What the job includes
  • /Load calculation & equipment selection
  • /Written scope before ordering
  • /Crane and rigging coordination
  • /Permit and inspection handling
  • /Start-up, balancing & commissioning
  • /Labor warranty on our workmanship

Thermostats, Controls & Electrical

Half of what gets called a compressor problem is a control problem. We troubleshoot and rebuild the control side: thermostats and smart controls, contactors, capacitors, transformers, safeties and staging, so equipment runs the sequence it was designed to run instead of fighting it.

Control and electrical service on refrigeration equipment
What the job includes
  • /Smart & programmable thermostat install
  • /Control panel troubleshooting
  • /Contactor, capacitor & transformer replacement
  • /Staging and sequence verification
  • /Safety and limit testing

Not sure which one you need?

Describe the symptom: short cycling, no cooling, tripping breakers, a failed inspection, and we’ll tell you what it actually is before anyone quotes you equipment.
