Subject: Application: HVAC Maintenance Technician, [Site or City]

Dear [Manager Name],

I would like to join the maintenance team on your contract at [Site or City] as an HVAC technician. For [x] years I have maintained heating, ventilation and cooling systems in office buildings and a hospital for [Current Company], both on scheduled rounds and during on-call periods.

I work on gas boiler rooms, air handling units, chillers and heat pumps. I hold electrical clearance and the refrigerant handling attestation, and I carry out combustion analysis and regulatory checks. Recently, repeated complaints about temperature on one floor came from a stuck damper actuator that the BMS reported as open; checking it on site instead of trusting the screen solved the issue.

I am used to working with site managers and occupants, explaining what was done and what needs planning. I enter every intervention and parts request in the CMMS so that the contract manager has an accurate view of the equipment.

On-call periods are already part of my routine. I would welcome a conversation about the contract, ideally with a walk through the plant rooms.

Kind regards,[First Name Last Name][Phone]

  • Ignoring the client type (hospital, offices), which shapes the job.

Frequently asked questions

Should I write a different letter for an in-house role on one site?

Yes. For a dedicated site, stress your relationship with occupants and the site manager and your knowledge of the building's systems. For multi-site rounds, stress autonomy, organisation and driving between clients.

How do I apply with only plumbing or electrical experience?

Explain which parts of HVAC you already cover, such as hydraulics or control panels, and the training you have started. Many companies accept profiles to complete with certifications if the base skills are solid.

Is it worth mentioning energy efficiency?

Yes. French regulations push building owners to reduce energy consumption, so technicians who can adjust settings, spot waste and suggest improvements are valued. Give one concrete example from your work.
