When your air conditioner or furnace breaks down, you rely on a local HVAC technician to get it running again quickly and honestly. Unfortunately, not every contractor operates with integrity. Some use deceptive tactics to overcharge customers or sell unnecessary services.
To help you protect your wallet and your home, here are 8 common HVAC repair scams to watch out for - and tips on how to avoid them.
1. The "Bait and Switch" Offer
Some HVAC companies lure customers in with offers that sound too good to be true - such as steep discounts, "free" tune-ups, or limited-time specials. Once inside your home, they'll try to upsell you on additional services or claim your system needs costly repairs.
If a deal sounds suspiciously cheap, it probably is. Always get multiple estimates before agreeing to any repairs, and be cautious of anyone pressuring you into a quick decision.
2. The Refrigerant Recharge Scam
Your air conditioner's refrigerant system is sealed - it shouldn't run low unless there's a leak. Dishonest technicians may "recharge" your refrigerant without fixing the actual leak, ensuring you'll need another service call soon.
Even worse, some charge for more refrigerant than they actually use. If possible, observe the process: refrigerant should be billed by weight, with the technician showing the before-and-after measurements.
3. "R-22 Is Illegal" Lie
Some contractors falsely claim that R-22 (also known as Freon) is now illegal to use. That's not true. While new production of R-22 ended in 2020, reclaimed or recycled refrigerant is still legal and available.
Systems using R-22 are more expensive to service - the refrigerant can cost $40 - $175 more per pound - but that doesn't mean you must replace your system immediately. Always verify what type of refrigerant your unit uses before agreeing to any replacement.
4. The "Cracked Heat Exchanger" Scare
A cracked heat exchanger is a serious issue - but also one of the most common furnace repair scams. Some unscrupulous technicians claim a crack exists when it doesn't, pushing you toward an expensive repair or full replacement.
If you're told your heat exchanger is cracked, ask for proof. A reputable technician will show you the crack and check for carbon monoxide leaks using a combustion analyzer or CO meter.
5. Unnecessary Part Replacements
Some contractors claim that multiple parts need replacing - even when they're functioning properly. Typically, only one component fails and causes the issue. Replacing several parts at once is rarely necessary unless the system is extremely old or neglected.
If a repair quote seems excessive, get a second opinion before spending money on major parts or a full system replacement.
6. Selling an Oversized Unit
Bigger isn't always better. Some companies push oversized HVAC units because they cost more to install - earning them a higher profit. However, oversized systems are less efficient, wear out faster, and create uncomfortable temperature swings in your home.
A trustworthy contractor will calculate your home's heating and cooling needs (called a Manual J load calculation) before recommending a new system.
7. No Price Breakdown
A legitimate HVAC company should clearly explain what's being repaired, why it's needed, and how much each part or service costs. Scammers often avoid giving details and present a single high-priced total to pressure you into replacing the system.
Always request a written, itemized quote that includes service fees, labor, and materials. Transparency is a hallmark of an honest technician.
8. Demanding Upfront Cash Payment
No reputable HVAC contractor should ask for full payment before performing any work. Scammers who insist on cash upfront often disappear before finishing (or even starting) the job.
A small deposit for parts or equipment may be reasonable, but full payment should only occur after the service is completed and verified.
5 Smart Ways to Avoid HVAC Scams
While most HVAC companies are honest and customer-focused, a few bad actors can give the industry a bad name. Protect yourself with these five simple steps:
1. Get a Second Opinion
If you doubt a diagnosis or quote, don't hesitate to call another contractor. A second opinion can save you hundreds (or even thousands) of dollars and help confirm whether a repair is truly needed.
2. Be Wary of "Free" Offers
Beware of "free inspections" or "special deals" that require quick decisions. These are often bait-and-switch tactics designed to get a salesperson into your home.
3. Insist on a Written Agreement
Never rely on verbal promises. A written estimate or contract protects you legally and ensures both parties understand the scope and cost of the work.
4. Check Reviews and References
Before hiring a company, read online reviews. A few negative comments are normal, but repeated complaints about scams or dishonesty are red flags.
5. Ask for Proof
If a technician says something is broken or unsafe, ask to see it. They should be able to show you the issue directly or provide clear diagnostic data.
