Paul Novak
Senior HVAC Service Technician, Southridge Home Services
Dear Paul Novak,
I'm applying for the Senior HVAC Service Technician position at Southridge Home Services. I'm EPA 608 Universal and NATE certified with 5 years in residential and light commercial service, and at Lakewood Comfort Heating & Air I run 5–6 service calls a day on heat pumps, gas furnaces and split systems with a 91% first-visit fix rate.
I try to find the real fault on the first visit and then explain the fix in plain words. Walking homeowners through the diagnostics and their repair options is also how I sold 110 maintenance plans in 2025.
I'm current on refrigerants, handling recovery, leak checks and charging on R-410A systems and newer A2L refrigerants such as R-454B. I also do preventive maintenance on 30+ commercial rooftop units under quarterly service agreements. Before moving to service, I was an installer at Tri-County Mechanical Services, where I installed 70+ residential systems, brazed and nitrogen pressure-tested line sets and ran Manual J load calculations with the lead tech.
I'd welcome the chance to talk about your service area and call volume. Thank you for considering my application.
Sincerely,
Andre Washington

/ Tips
Tips for your HVAC technician cover letter.
01
Lead with certifications
EPA 608 and any NATE certifications belong in the first paragraph. Many shops screen for them.
02
Use a first-visit fix rate
If you track it, it's the clearest single number for a service manager.
03
Show how you talk to customers
Service techs represent the company in people's homes. One line on how you explain repairs goes a long way.

Do HVAC technicians need a cover letter?
Many shops don't require one. A short letter helps when you're applying for a senior or commercial role, or moving to a new company or area.
Should I mention A2L refrigerant experience?
Yes, if you've worked with A2L refrigerants or completed training on them. Say what you've handled in one line.
