Free St. Louis HVAC Repair Cost Estimates

If you’re not into pushy sales associates without any real world experience in St Louis HVAC installations and service then you’re at the right place. We only send educated, journeyman level heating and cooling technicians or HVAC engineers to give you the facts for your heating and cooling estimate. We don’t work off commission just the joy of delivering heating and cooling comfort to our customers.

Don’t assume your heating and cooling company is delivering ultimate value until you talk to the pros at Dunn Heating & Cooling.

An in-home HVAC consultation is the ultimate way to ensure you are getting the best value. Yes, we can do phone HVAC consultations if the caller insists, but it is a disservice for us not to visit the home. We cannot count the number of times we have caught serious HVAC safety hazards in the home that other heating and cooling companies in St Louis missed.

Whole Home Energy Audit.

We have the ability to analyze the energy consumption of each individual component of your home.  Our state of the art software program details the exact energy loss of each component allowing you to make energy improvement decisions based on greatest return on investment.
