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.

2)    Rehagen HVAC is certified in the below categories.  Ask other HVAC contractors if they    are certified in the following:
       1)  IGSPA Certified geoexchange designer
       2)  Certification in Geo Piping Loop Design
       3)  Certification in Fusion Welding Technology
       4)  Certification with Missouri Department of Natural Resources and Environmental Quality                  Well Drillers and Pump Installers  
       5)  Personnel trained in Manual J load calculation 
       6)  Certified Hydronic Floor Heat Engineer
       7)  Full liability and workmen's compensation insurances  
       8)  All employees of company fully OSHA certified

What people are saying about REHAGEN


"When it came time to install a central heating and AC system in my mother's one-hundred-year-old home,
Rehagan Heating and Cooling came highly recommended by a friend. They did the installation in a timely and cost-efficient way. When my own home needed a new A/C unit installed several months later, I contacted Rehagan's and they did as nice of a job on my home as they did with my mother's home. We are pleased with the work and would highly recommend them to anyone needing heating or cooling work." ......Larry, Lake of the Ozarks, MO

"I was very impressed from the moment I made the call until the installation was completed. Very courteous, timely and friendly. There is not one thing that I could complain about. Great Job!" Thanks, Ann, Centertown, MO

He came back and explained everything again for my husband, was open to a different idea when we wanted something different than what he originally proposed. So great to work with!!
