First, A Quick Recap… 

As a heating and cooling provider, I get some of these questions over and over again. The questions have been compiled for you to find a HVAC service provider that can do the job correctly. There is plenty of competition in the HVAC business but it is not difficult to find a qualified technician as long as you know what to search for. 

To narrow down your decision you can search a few companies online and comparison shop. Depending on the work you need done, look at the differences and similarities the businesses display. Not all HVAC companies or HVAC technicians are created equal.

5 Easy Steps to Take When Choosing a HVAC Technician  

Step 1: Check Their Experience

For obvious reasons, technicians should have completed a few jobs. It's in your best interest to work with up to date and experienced contractors. Less qualified companies may not keep their employees or technicians current with the latest technology. This may cause you from having a newer or more current design.     

Step 2: Check Their Credentials 

Most established contractors are properly certified. The HVAC Excellence is a certification program for HVAC technicians that will ensure their work quality through validation and continuing education. All certifications should be up to date. You can also find qualified technicians through such organizations as:

You should also consider what the required licenses are for your state and if there are contractors that meet them. Liability insurance should also be used to compare technicians. Insurance will protect your property and workers if anyone gets hurt.

Which HVAC Certifications do Technicians Need? 

Step 3: Ask for Estimates  

Getting the best price is always good, but make sure you are getting the best service with that price. Ask for estimates from candidates and compare what each offers for their price.

You should only consider price after finding the most qualified. In the end it will save you money. 

Step 4: Check Their References 

Before a person gets hired at a new job, the employer asks for references. You should do the same with hiring a HVAC technician. It's often a great place to start with recommendations from friends and family in the area.

There are also online directories that list companies that are verified as good options.  

Step 5: Read Reviews and Testimonies

You should consider reading some reviews from past customers of technicians. You can usually find these on their website. Online directories may also post reviews. Good and not so good reviews can be the determining factor for which HVAC technician you choose.
