Let’s be honest—choosing an HVAC contractor shouldn’t feel like rolling the dice. But in St. Clair County, just like everywhere else, not all contractors are created equal. Whether you’re replacing your aging system or need a quick repair, hiring the wrong person can lead to delays, damage, and serious financial regret.
At S&P Heating, we believe in making HVAC simple, straightforward, and drama-free. That’s why we’re sharing this guide on how to spot the warning signs before you commit. If you’re shopping for a new HVAC contractor, these red flags can help you steer clear of shady deals and poor service—and keep your home in cool, cozy shape year-round.
1. No License, No Deal
This one’s a dealbreaker. If someone shows up at your house offering unlicensed HVAC repair, show them the door. A professional HVAC contractor must be licensed and certified in the state of Michigan to work in St. Clair County.
No license means:
- No accountability
- No insurance coverage
- No guarantee the work meets code
Always ask to see proof of credentials. If they get weird about it? That’s your first red flag.
2. Vague Estimates and Zero Paperwork
If a contractor offers a quote over the phone without seeing your system—or worse, refuses to give anything in writing—you’re headed for trouble. One of the biggest contractor red flags is a lack of documentation or clarity.
Look out for:
- Handshake agreements
- No formal bid or contract
- No itemized breakdown of services
This sets you up for hidden HVAC fees, bait-and-switch pricing, or unauthorized work.
3. No Reviews—or Suspiciously Perfect Ones
Online reputation matters. If a contractor has no online reviews available—or only a few suspiciously glowing reviews with zero detail—proceed with caution. Even the best pros occasionally get four stars instead of five.
Warning signs include:
- Only reviews from brand-new accounts
- Reviews posted on the same day
- No pictures or local context
Do your homework and ask for referrals. A reputable HVAC contractor will happily provide references from real St. Clair County customers.
4. High-Pressure Sales Tactics
We’ve all met the upsell king—the guy who walks in for a filter change and leaves recommending a full system replacement. Sure, sometimes you need major work. But upselling pressure should never be the first move.
If a contractor pushes:
- Brand-new systems over repairs
- Extended warranties you don’t understand
- Add-ons with no apparent benefit
…slow things down and get a second opinion. A trusted HVAC expert should educate—not intimidate.
5. No Service Guarantee or Warranty Policy
No matter how good someone is, things can go wrong. That’s why reputable contractors offer warranties and service guarantees.
Red flags include:
- Vague language about follow-ups
- No mention of a service guarantee
- Evading questions about return visits
If they won’t put their work in writing, how can you trust they’ll fix it if something fails?
6. Poor Communication from the Start
Did they show up late to the estimate? Take days to respond to your call? Forget your name three times? These are all signs of communication breakdown—and that won’t magically improve after you sign the contract.
Clear, respectful communication is a baseline for any home service provider. Don’t settle for less.
7. A Too-Good-To-Be-True Price Tag
We get it. Everyone loves a deal. But be careful when it comes to suspiciously low pricing. Why?
Because cutting corners is the only way to make those margins work. That could mean:
- Cheap materials
- Undertrained workers
- Rushed jobs
- No permits pulled
Always compare quotes from multiple HVAC contractors and watch out for any bid that undercuts the others by a mile.
8. Shady HVAC Practices on the Job
Sometimes, the red flags don’t show until the work begins. Stay alert during the installation or repair process. If a tech seems rushed, distracted, or overly secretive, you may be witnessing shady HVAC practices firsthand.
Examples include:
- No protective floor covers
- Leaving tools and trash behind
- Not explaining what they’re doing
- Cutting corners on key steps
You’re paying for quality—make sure you’re getting it.

FAQ: HVAC Contractor Red Flags in St. Clair County
What should you do if a contractor refuses to give you their license number?
Walk away. Licensing is a legal requirement in Michigan for HVAC work. Any contractor who avoids sharing their license number—or says you don’t need it—is either not qualified or hiding something. You can verify a license through Michigan’s Department of Licensing and Regulatory Affairs (LARA). A reputable contractor will always provide credentials up front and with confidence.
How can you verify a contractor’s insurance coverage before hiring them?
Ask for a copy of their general liability and worker’s compensation insurance certificate. You can also call the insurance provider listed to verify the policy is active and up to date. Never hire an HVAC contractor who cannot prove they’re insured—if damage occurs or someone gets hurt on your property, you could be held liable.
Are big HVAC companies always a bad choice?
Not necessarily! Some large HVAC chains do offer consistent service and professional installations. But the downside is you may deal with less personalization, slower response times, or lack of transparency due to the sheer size of their operation. Local contractors tend to provide more tailored service—and they’re more accountable to their community.
