Why Preventive Maintenance Matters
Lower Bills and Better Efficiency
Your HVAC and plumbing systems account for a significant portion of your home’s energy use. Heating and cooling alone can represent more than one third of a home’s total energy consumption.
Fewer Breakdowns and Longer System Life
Routine maintenance helps ensure maximum system efficiency, fewer unexpected breakdowns, longer equipment life, and improved safety and reliability. Preventive care today can help you avoid costly repairs tomorrow.
Regular inspections help identify small issues before they become major problems.
Safety and Home Protection
- Dirty coils, blowers, or components can increase energy usage by up to 50 percent.
- Dirt buildup on motors and fan blades increases friction, reduces airflow, and accelerates wear.
- Low refrigerant levels can significantly increase operating costs.
- Many system failures are caused by a lack of routine maintenance.
- Cleaning and inspections help prevent breakdowns in furnaces, heat pumps, air conditioners, and plumbing systems.
- Valve tagging helps you quickly shut off water during plumbing emergencies.
- Leaky ductwork allows conditioned air to escape before it reaches your living space.
Preventive maintenance leads to fewer failures, longer system life, and better comfort throughout your home.
What’s Included in Each Inspection
- HVAC Tune-Ups (2 Per Year)
- Plumbing Safety Inspection (1 Per Year)
