Top Warning Signs of an Inferior HVAC Contractor


When you hire an HVAC contractor to repair or replace your heating and air conditioning unit, it’s important that you hire a professional who is trustworthy and skilled. There are some contractors who are of a higher caliber than others. For such an essential home appliance, you want to work with someone you can rely on, so watch out for these warning signs of HVAC contractors to avoid.

HVAC Contractor

Unbelievably Low Prices

If a contractor gives you a rock-bottom estimate that seems too good to be true, it probably is. Sometimes, unscrupulous contractors bid extremely low just to get the job. Once they’re awarded the contract, they may use low-quality materials, fail to meet deadlines, and/or not be licensed to do the work. Low bids may not include everything needed to get the job done, and when the “extras” are added on, the total price might turn out to be much higher than you expected. If you get a bid that’s unbelievably low, you better think twice before believing it.

Bad Online Reviews

It’s wise to go online and read what past customers have said about the HVAC repairpersons or installers you’re considering hiring. While one bad review might just be a disgruntled customer, several unfavorable reviews should be taken more seriously. When reading reviews, look for specific details, dates, and check more than one online-review website. Take note of patterns, positive and negative.

Poor Customer Service

If you receive poor customer service from contractors as you’re gathering estimates, just think of how bad it might get if you actually hire them. Here are some telltale red flags to be on the lookout for:

  • Tardiness: If your contractor doesn’t show up on time to give you an estimate, know that the trend will probably continue during the installation or repair. Promptness shows reliability.
  • Sloppy appearance: The installer or repairperson should arrive at the job dressed like a professional. He or she should also protect your home by wearing service booties or using carpet runners to keep your home neat and tidy.
  • Unclear communication skills: Being able to communicate with your HVAC contractor is crucial. Make sure your contractor doesn’t speak in buzzwords of the business that you can’t understand. If you don’t know what he or she is talking about, ask for clarification. If you still don’t understand what the individual is trying to say, move on.

No Business History

How long has the company been in business? You want to hire an HVAC company that has a track record. When a company is well established, it’s usually because they run a tight ship, have happy customers, and know what they’re doing. You want to do business with a company who will be around when you need them next year or five years from now.


As you’re gathering estimates, ask about each potential HVAC contractor’s insurance. Make sure there is adequate coverage in case one of the technicians gets injured on the job or if damage occurs at your property. The company should carry liability coverage and workers’ compensation.

When you do your homework ahead of time to avoid inferior contractors, you will be much better off in the long run. Ask plenty of questions, do some online sleuthing, and find a top quality professional who will perform great work.
