Choosing who works on your heating and cooling isn’t just about comfort. It’s about safety, trust, and making sure your home or business can keep running—no matter what. When your AC goes out in a heatwave or a furnace fails in the dead of winter, there’s no time for guesswork.

At Briggs Heating, we know exactly how stressful emergency HVAC breakdowns can be. That’s why we believe every customer deserves clear answers before hiring any contractor—ours or anyone else’s.

9 Key Questions to Ask Before You Hire an HVAC Contractor

Think of hiring an HVAC contractor like picking a pilot for a stormy flight. You need someone qualified, reliable, and ready to take charge when things get bumpy. Here are the nine questions every homeowner or business manager should ask—before signing any contract or agreeing to repairs.

1. Are You Licensed for HVAC Work in This Area?

Ask for a state-issued HVAC license. This proves the contractor has passed required exams and understands building codes. Most states require licensing; you can check requirements through the U.S. Department of Energy or your state’s consumer protection agency.

2. Do You Carry Liability Insurance and Workers’ Compensation?

If something goes wrong on your property, you want to know you’re protected. Ask for up-to-date certificates. This shields you from financial risks if a worker is injured or property is damaged.

3. How Much Experience Do You Have with My Type of System?

Not all HVAC systems are created equal. Whether you need AC repair near you, radiant heating, or a mini-split installation, experience matters. Ask if they’ve worked on your brand and model before—especially for commercial or specialized systems.

4. Can You Provide References from Recent Jobs?

A trustworthy contractor won’t hesitate. Ask for feedback from both residential and commercial clients. Real-world reviews can reveal how contractors handle emergencies, delays, and follow-up service.

5. What Warranties or Guarantees Do You Offer on Your Work?

Don’t settle for vague promises. Get clear details on what’s covered, for how long, and by whom. While it’s common for parts and labor to be warrantied, always get it in writing.

6. Which Brands and Models Do You Install or Service?

Some contractors are certified for specific brands. Knowing this helps if you need specialized repairs, like geothermal systems or energy audits. Ask if they have access to parts for your specific system.

7. Is Your Pricing Up-Front? Will I Receive a Written Estimate?

No one likes surprises—except maybe on birthdays. Ask for a detailed, written estimate before work begins. This should include labor, materials, and any potential extra costs. Up-front pricing builds trust.

8. Do You Offer 24-Hour Emergency HVAC Service?

Breakdowns don’t wait for business hours. If your furnace dies at 2 a.m., you want to know help is on the way. Confirm they truly provide emergency HVAC support and how quickly they can respond.

9. How Well Do You Know Local Codes and Weather Needs? 🌦️

Every region has unique challenges—humidity, wild temperature swings, or local code quirks. Local knowledge means better, safer solutions, whether it’s choosing the right air scrubbers or optimizing your ventilation.

Red Flags: When to Pause or Walk Away

Just as you wouldn’t board a plane with broken wings, don’t settle for a contractor who can’t answer basic questions. Watch for these warning signs:

  • Missing Documentation: No proof of licensing or insurance.
  • Vague Answers: Dodges questions or gives non-committal replies.
  • No Written Estimate: Insists on verbal quotes or won’t provide paperwork.
  • Pushy Sales Tactics: Pressures you to sign now or pay upfront.
  • No Physical Address: Only a P.O. box or untraceable contact info.

If you spot any of these, it’s time to look elsewhere.

Ensuring Quality: Certifications, Training, and Reviews

How can you tell if a contractor is at the top of their game? Look for these signs:

Certifications & Professional Memberships

Reputable HVAC contractors often hold certifications from groups like:

  • North American Technician Excellence (NATE)
  • EPA Section 608 Certification for refrigerant handling
  • Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA)

These prove ongoing training and commitment to industry standards.

Ongoing Training

HVAC technology changes fast. Ask how the company keeps up with new systems—like air balancing, air scrubbers, or whole-house fans.

Customer Reviews and Ratings

Public feedback is a powerful mirror. Check sites like the Better Business Bureau, Google Reviews, or your local consumer protection office. Consistent praise—or repeated complaints—can tell you a lot.
