HVAC Maintenance & Repairs

Prevent Downtime. Protect Your Investment.

Stop putting out fires. Our proactive HVAC maintenance plans are designed to maximize system uptime, minimize energy waste, and detect issues before they become costly failures. CRS Mechanical provides ongoing service for commercial and industrial HVAC systems across New Hampshire—with responsive emergency repairs when you need us most.

Maintenance Services Include:

  • Our seasonal tune-ups ensure your equipment is running efficiently when you need it most. We inspect, test, and optimize all system components to prevent breakdowns, extend lifespan, and reduce energy costs during high-demand months.

  • Dirty filters and coils reduce system efficiency and indoor air quality. We replace filters and thoroughly clean condenser and evaporator coils to maintain proper airflow, prevent freeze-ups, and protect your investment from premature wear.

  • Low refrigerant levels or undetected leaks can cripple cooling performance and drive up operating costs. We perform EPA-compliant leak testing, recharge refrigerant to proper levels, and ensure pressure readings are balanced for peak efficiency.

  • Modern HVAC systems rely on accurate sensors and controls to function properly. We calibrate thermostats, sensors, and control panels to ensure your system responds efficiently to building needs—avoiding unnecessary run time and improving occupant comfort.

  • Worn belts or unbalanced motors can cause system failures and excessive noise. Our team inspects and adjusts all drive components, lubricates moving parts, and replaces worn belts before they snap—keeping downtime off your calendar.

  • Using advanced tools and monitoring, we evaluate system health in real time. Our diagnostic checks uncover hidden inefficiencies, early warning signs, and wear patterns—allowing us to recommend proactive service before a failure hits.
