WaterFurnace news story
At Rehagen Heating, Cooling and Plumbing our main goal is for our customers to have the lowest possible energy bills.   As the most experienced geothermal dealer in Central MO, we use the latest engineering technology and sizing programs available.  Sizing is crucial!  Mistakes made during the installation process can be a lifetime affair.  If a sizing mistake is made you may never recoup your investment.  We urge you to do your homework when choosing an HVAC contractor (see our "Why Rehagen HVAC" page for a list of info to consider when choosing a dealer).  Be sure to ask for past customer references and make sure your HVAC dealer is fully insured and certified.
