Your Air Conditioner Startup Checklist
Winter is finally over and it’s time to prepare your HVAC system for the warmer season. Turning on your AC after winter can cause problems for your overall HVAC system if it’s not done properly. Follow this chiller startup checklist to prepare your air conditioner for summer:
Start with a visual inspection of your AC unit to look for obvious issues. Check for:
- Loose or missing covers and panels
- Malfunctioning control panels and internal compartments
- Refrigerant leaks
- Presence of any oil
If you notice a refrigerant leak or outstanding oil, immediately contact a professional HVAC contractor, especially if your refrigerant is outdated.
Leaks like this can lead to poisoning, difficulty breathing, eye irritation, and severe coughs, so an expert needs to take care of it as soon as possible.
Check Power Source and Control
Before your air conditioner startup, check your power and control sources for signs of overheating, tightness, and cosmetic damage. If you notice anything loose or too hot, contact an HVAC repair company to fix the issue—doing so yourself could lead to further damage.
If your AC unit has a mechanical contactor, have the contactor disassembled and inspected for arcing and wear. Ensure your safety cutouts are properly set and working to avoid future problems.
Review Winter Operation Logs and Service History
Operation logs and service history help HVAC technicians better understand your unit. This information highlights any previous damage, maintenance, and repairs, so your contractor knows what has been a problem in the past.
The technician can also make better recommendations for upkeep before your air conditioner startup, so it works efficiently in between maintenance checks.
Hire an HVAC Contractor for a Professional Inspection
The most critical step in getting your air conditioner ready for summer is hiring a professional HVAC expert to inspect your unit.
HVAC contractors notice problems that you may not have recognized during your initial inspection. Plus, they can replace and repair any damaged parts since they have access to the proper equipment.
Repairing your AC unit without any professional experience can be dangerous. You could expose yourself to outdated refrigerants or hurt yourself trying to make repairs on your own. When in doubt, always contact a professional.
Starting Up Different Types of Air Conditioners
Different businesses require different types of ACs. Here’s a breakdown of how to start up the most common types of industrial AC units:
When starting your water chiller for the summer, make sure the chiller operates correctly by checking the refrigerant and paying attention to:
- Condenser coil cleanliness
- TXV installation
- Clearance around the outdoor unit
- Oil return systems (for larger water-cooled units)
Cooling Towers and Ancillary Equipment
Properly running cooling towers are essential to your air conditioning system. Building owners, facility managers, and property management professionals must complete regular visual inspections of their cooling towers when starting their chiller plants.
If you have a cooling tower or other ancillary equipment:
- Clean the sump
- Check distribution nozzles
- Make sure the fill valve is tightly shut off
- Clean the filters and strainers
- Lubricate the condenser
An HVAC contractor should evaluate the energy efficiency of your cooling system every summer. Ensure your AC unit is running as efficiently as possible to prepare for the hotter season—if it’s not, hire a technician to install:
- Building automation system upgrades
- Speed drive retrofits
- Chiller plant automation
- Condenser water reset
- Optimal start/system functionality
Outdated chiller plants waste energy and money and decrease your air quality, so have an expert evaluate your HVAC system’s energy efficiency during air conditioner startup.
