Not all HVAC technicians are the same. Some show up late, offer vague pricing, or aren’t equipped to handle your system. Asking the right questions up front can save you time, money, and frustration later. Here’s what to ask before hiring someone to work on your heating or cooling system:

Are They Licensed and Insured?

It might sound obvious, but don’t skip this step. A licensed HVAC tech has the training and certifications required to do the job safely and legally. Insurance protects you if something goes wrong—like property damage or injury—while they’re working.

Do They Have Experience With Your Type of System?

Not every technician has seen your specific setup before. Ask how long they’ve been in the field and whether they’ve worked with systems like yours. Experience matters, especially if you have a heat pump, radiant system, or older unit that might not be standard.

Will They Give You a Written Estimate?

Verbal quotes leave room for surprises. A clear, written estimate should include labor, parts, and any other fees. You’ll avoid miscommunication and know what to expect before the work starts.

What’s Their Customer Service Like?

You can learn a lot from how a technician handles questions. Do they return calls promptly? Are they clear and direct? Ask what their process looks like if something goes wrong after the job is done. The answer tells you whether they’ll still pick up the phone once you’ve paid the invoice.

Are They Familiar With Current HVAC Technology?

Systems have changed a lot in the last 10 years. From smart thermostats to high-efficiency heat pumps, your technician should be up to date. Ask if they’re comfortable working with newer equipment or recommending energy-saving upgrades.

Do They Offer Maintenance Plans?

Routine maintenance helps prevent surprise breakdowns and extend the life of your system. Ask what’s included in their maintenance plan and how often service is performed. At C-U Trade Services, we offer HVAC service plans that include priority scheduling, regular inspections, and discounts on future repairs.

How Do They Handle Emergencies?

When your AC dies in a July heatwave, you don’t want to be stuck on hold. Ask if they offer emergency services and what kind of response time you can expect. It’s worth knowing before you’re in a bind.

What Financing Options Are Available?

HVAC repairs and replacements aren’t cheap. A reputable company should have clear financing options. At C-U Trade Services, we offer financing through Wells Fargo to help you spread out payments without stretching your budget.

The Bottom Line

Hiring the right HVAC technician isn’t just about price—it’s about trust, clarity, and preparation. Ask these questions early so you can feel confident about who’s working on your system.
