A bad hire — or losing a good tech — quietly costs you thousands in callbacks, lost productivity, recruiting, and the morale hit on the way out. Winging it on hiring is one of the most expensive habits in the trade. Here's how to do it right.
Your first hire is the scariest one. Until now the quality of every job was on you. The moment a tech is in a truck with your name on the side, your reputation is in their hands. Do this right and you buy back your time. Do it wrong and you spend months cleaning up callbacks. Here's how to stack the odds.
Step 1: Know what the hire actually costs
Before you post a job, run the math. A tech's loaded cost is far more than their hourly wage — add payroll taxes, workers' comp, health benefits, the truck and gas, tools, phone, software seats, and uniforms. The wage might be $30/hour but the loaded cost can land closer to $45–55/hour. Price your jobs off the loaded number (see the pricing guide) or the new hire quietly loses you money.
Step 2: Decide what you're really hiring for
You have two paths:
- Experienced tech: Productive on day one, costs more, and may bring habits you'll have to un-train. Best when you need capacity now.
- Apprentice / helper: Cheaper, moldable, and loyal if you invest in them — but a drag on a senior tech's time for the first stretch. Best when you're building a bench for the long haul.
For most first hires, a solid mid-level tech or a sharp helper you can grow beats overpaying for a senior tech who'll be bored.
Step 3: Find them where they actually are
- Your network first. The best hires come from techs you've worked alongside, supplier reps' recommendations, and your current customers' referrals.
- Local trade schools. Build a relationship with the HVAC program at your community college — first pick of graduating apprentices.
- Job boards & Indeed. Work, but you'll sift more. Write the post like a sales pitch, not a wish list.
- Always be recruiting. Keep a posting up even when you're not desperate. The best techs aren't looking when you suddenly need them.
Sell the job, don't just list it
Good techs have options. Your posting should lead with what makes you a great place to work — steady hours, modern trucks, no callbacks because you do it right, real growth — not a five-paragraph list of demands. You're recruiting, not gatekeeping.
Step 4: Screen for character, test for skill
Skills can be taught; showing up, honesty, and how they treat a customer can't. Screen hard for character on the phone and in the interview, then verify skill with a practical test — walk them through a real diagnostic scenario or have them spend a paid half-day ride-along. What they do beats what they say.
- Do they show up to the interview on time and clean? That's a preview.
- Ask about a job that went wrong and how they handled it — listen for ownership vs. blame.
- Check references, actually call them, and ask "would you hire them again?"
Step 5: Keep them (this is where shops fail)
Recruiting a replacement costs far more than keeping a good tech. Most techs don't quit over money first — they quit over disrespect, chaos, and feeling stuck. Fix the cheap stuff:
- Pay fairly and on time, every time. Non-negotiable baseline.
- Good tools and trucks. Nothing burns out a tech like fighting broken equipment all day.
- Respect and clear expectations. No screaming, no last-minute weekend surprises, no moving the goalposts on pay.
- A path forward. Pay for certifications, map out helper → tech → lead → manager. People stay where they can grow.
- Recognition. Call out great work in front of the team. It's free and it works.
The retention math
Replacing a tech can cost thousands in recruiting, training, lost productivity, and callbacks — plus the hit to morale. A raise, better tools, and basic respect are almost always cheaper than turnover. Treat keeping your team as a line item worth protecting.
Should I hire an experienced tech or train an apprentice?
+If you need capacity right now and can afford it, an experienced tech produces immediately. If you're building for the long term and have a senior tech who can mentor, an apprentice is cheaper and tends to be more loyal. Many growing shops do both: one experienced hire for capacity, one apprentice for the bench.
How do I compete on pay with bigger HVAC companies?
+You usually can't out-spend the big players on base pay alone, so compete on the things they're bad at: respect, flexibility, better tools, a real growth path, and a culture where good work gets noticed. Many techs leave large companies precisely for a smaller shop that treats them like a person. Pay fairly, then win on everything money can't buy.
When am I ready to make my first hire?
+When you're consistently turning away work or working dangerous hours to keep up, and you have enough steady lead flow and cash cushion to cover the new tech's loaded cost for a few months even if revenue dips during onboarding. If the demand is there and your pricing covers the loaded cost, it's time.
