How to Find an HVAC Company You Can Trust

Before you make a big investment in a new heating or cooling system—and even before you call someone to come to your home and fix the one you have—do a little homework. It’s important to find an HVAC company you feel comfortable with.
Online Reviews for Heating and Cooling Experts
Most people start by asking friends and neighbors who they use, or they do an internet search and compare online reviews. Companies like Gross Heating & Air Conditioning will stand out with high ratings on Google, Angie’s List, and the Better Business Bureau.
Choosing the Best Contractor
This is a great way to get a feel for the customer experience with an HVAC company, but make sure you also compare capabilities and credentials. Here are some things to look for to get the best service from a skilled provider:
- Established and experienced
- NATE-certified technicians
- EPA certifications for handling refrigerants
- Bonded and insured
- Carrier® Factory Authorized Dealer
- Able to service ALL makes and models of home comfort systems
- Guarantee on service
- Warranty on products
- Free in-home consultations and estimates
- On-call emergency service
Don’t Panic If Your Furnace or AC Breaks
When something in your home breaks down, you want it fixed right away—but that doesn’t mean you need to hire the first HVAC company with an opening in their schedule. Ask questions and take the time to find someone who will treat you just right.
If you have questions, we hope you’ll contact Gross. We’ll never pressure you or take advantage of a home emergency because we don’t just want to fix your furnace or air conditioner today—we want to be the HVAC expert you’re comfortable calling year after year.
