Before You Hire

Facilities usually schedule HVAC contractors at least twice a year, before cooling and heating seasons. Ask:

  • Do you take commercial work, and do you service buildings like ours?
  • Can you send a certificate of insurance naming us as additional insured?
  • Are your technicians EPA Section 608 certified to handle refrigerant?
  • Do you service our equipment type and brand (rooftop units, chillers, boilers)?
  • What does a service agreement include, visit by visit?

Hiring Tips

  • Change filters on a schedule set by your dust load, often every 1–3 months.
  • Keep a list of every unit with its model, serial number and age.
  • Compare repair quotes against the unit's age before replacing it.
