Maintenance Tips and Quick Fixes
For Homeowners
How to prevent frozen pipes during Wisconsin winters
Keep cabinet doors open so warm air reaches your pipes, insulate exposed pipes, and let faucets drip during sub-zero nights to prevent freezing.
Simple ways to improve water pressure
Check for clogs in aerators, clean showerheads, and have your pressure regulator inspected by a plumber.
Signs your water heater needs maintenance
Rust-colored water, inconsistent hot water, or rumbling noises are signs your water heater may need service.
Replacing furnace filters
Most filters should be replaced every 1–3 months, but it depends on filter type, pets, and home air quality.
Preventing drain clogs in bathrooms and kitchens
Use drain screens, avoid flushing wipes or grease, and clean stoppers regularly to reduce clogs.
For Business Owners and Facility Managers
Routine checks to avoid HVAC shutdowns
Inspect belts, filters, thermostats, and outdoor units monthly. Schedule professional service each season.
Drainage and grease trap tips for commercial kitchens
Avoid overusing disposal systems, clean traps regularly, and have grease interceptors sized and cleaned as needed.
Preventative maintenance planning for large systems
Log routine inspections, keep a maintenance checklist, and service critical systems quarterly or biannually.
What to do when a commercial boiler shows signs of failure
Shut off the boiler and call a technician immediately—unusual smells, noises, or leaks are red flags.
Understanding seasonal load demands on HVAC systems
Plan for peak cooling/heating needs in spring and fall. Clean filters and schedule load testing pre-season.
