Healthcare HVAC Maintenance in Southeast Michigan

Written by Jake Pence | Oct 12, 2026, 3:15:48 PM

Medical offices, outpatient clinics, dental practices and care facilities depend on steady temperature, humidity and air movement. When the HVAC goes down, patients and staff feel it right away. Air Handlers Service Group has maintained commercial HVAC across Southeast Michigan since 1985. Here is what healthcare facility managers should focus on.

Why healthcare buildings need closer attention

  • Patient comfort: People who are sick, elderly or recovering are more sensitive to heat and cold.
  • Humidity: Michigan winters are dry and summers are humid. Humidification and dehumidification keep conditions steady.
  • Air movement: Exhaust fans, make-up air units and VAV boxes need to work as designed so each room gets the air it should.
  • Uptime: A clinic cannot easily close for a day because a rooftop unit or boiler failed.

Maintenance checklist

Every visit

  • Change filters on the schedule your equipment and facility require
  • Check belts, motors and bearings
  • Clear condensate drains and pans
  • Verify thermostat and building automation setpoints

Cooling season

  • Clean condenser and evaporator coils on rooftop units
  • Check refrigerant circuits and compressors
  • Test economizers

Heating season

  • Inspect boilers, burners and safeties
  • Check humidifiers and make-up air units
  • Test exhaust fans and confirm airflow

Keep records

A written report after each visit shows what was checked and when. It makes questions from owners, landlords or inspectors easy to answer.
