How do I choose the best company to fix my HVAC system?
When your HVAC system isn’t working properly, you’ll need to hire a reputable company to repair it. Here are some of the qualifications to look for:
Licensure: Look for companies that employ technicians with the required licensing and certifications for your area. For example, find out if the technicians have HVAC licenses and NATE or EPA 608 certifications.
Insurance and warranties: Find out if the company backs its repair work on HVAC systems with a warranty for workmanship and parts. You should also hire a company that is bonded and insured.
Cost estimates: Obtaining several estimates helps ensure you’re not overpaying for HVAC services. Review the companies’ labor, materials and service call fees so you’re not surprised by any costs.
Reviews: Reach online reviews for each company you’re considering. Keep a lookout for similar complaints, especially if there’s a concern about the HVAC technicians’ quality of work.
Questions: Ask the company many questions before hiring them. For example, make sure they’re familiar with your HVAC system (split systems, heat pumps, ductless mini-splits, etc.) and ask them how long the project will take.

What's the key difference between an HVAC technician and a contractor? And which one should I hire for my project?
While some companies and professionals might use these two terms interchangeably, there’s sometimes a difference:
An HVAC technician is a trained professional who typically handles repairs, maintenance and installations. They generally focus on specific, hands-on tasks like fixing systems or performing tune-ups.
An HVAC contractor, on the other hand, usually oversees larger projects, manages teams and ensures compliance with codes and permits. They can make repairs, but they might also send technicians to perform those repairs. They are licensed to manage entire projects, including design, installation and compliance with local regulations.
In some cases, a technician is sufficient for small repairs or maintenance. For major repairs and installations, system replacements or complex projects, you might want to hire an HVAC contractor first.
What are the benefits of hiring a local HVAC pro vs. trying to DIY your project?
Installing or repairing HVAC equipment yourself may sound like a shortcut around delays, but it could be the opposite. It’s easy to make mistakes, and fixing those mistakes can delay your project even more.
Before you DIY this project, consider the benefits of hiring a licensed HVAC professional:
Being licensed means they’ve completed the training and have acquired the skills to work on your HVAC system efficiently and properly.
Local technicians and contractors understand local code requirements and the permit process, which can be a big learning curve for the novice DIY-er.
HVAC pros can also assist with product registration to prevent voiding the warranty. Some manufacturers might even require this.
Installation or replacement might come with a discount or a period of free routine maintenance.
A DIY installation of indoor and outdoor components, ductwork, refrigeration lines and electrical connections places a huge burden on your time. Plus, any mistakes could cause significant system issues. Hire an HVAC technician or contractor to repair or install your new system safely, efficiently and, most importantly, correctly.
