Why Choose Rehagen HVAC and Plumbing?


3)     HVAC contractors should be glad to give numerous past job references.

4)     Any reputable HVAC contractor will not charge for an estimate.

5)     Always insist on a Manual J sizing load calculation so sizing is accurate. 

6)     An experienced geothermal dealer will offer a free HVAC Home Energy Audit and will include an 
        ARHI certificate upon request.

7)     HVAC contractors should be aware of the different rebate program rules, regulations and tax 
        incentives.

8)     Ask other HVAC contractors if they custom build their sheet metal duct or if they install prefabricated duct.

9)    Most importantly, make sure you are comparing apples to apples.  When you are getting multiple bids 
be sure to compare tonnage size, EER rating, COP rating, ECM Motor and Warranty. If there is a drastic 
difference in cost there is probably a good reason. Do your homework.  Sometimes a cheaper bid will end up 
costing you much more in the long run.  


1)  Experience matters!  Ask other HVAC contractors how many geothermal systems they have installed! This is a sizable investment, don’t take chances.  Mistakes made during the installation process can be a lifetime affair.  If a sizing mistake is made you may never re-coup your investment.  In 2012 Rehagen HVAC was named #1 independent dealer in the NATION! We currently have over 2,000 systems on the market. Always make sure the HVAC contractor you choose is fully licensed and insured.
