Comparing HVAC Estimates

When you need major heating and air conditioning work such an HVAC replacement and installation, you should obtain estimates from two or three different HVAC contractors before starting work.  By getting several estimates, you will have the opportunity to meet each of the HVAC contractors and evaluate whether you would be comfortable having them do the work.

In addition, you will be in a better position to make sure that you are getting a high quality unit installed at a reasonable price.  Some people automatically choose the lowest estimate thinking that they will save money.  This can be a major mistake.  The lowest estimate is not always the best one.  The contractor may be “low-balling” the estimate to get the job, then will add on other costs later after the work has already begun. 

Also, in some cases a low estimate is an indication that the contractor will be installing lower quality or undersized equipment.  Compare the size of the unit in each estimate. Any significant discrepancies call for further investigation.

You can also compare the quality of the equipment by comparing the warranty period.  The warranty is not a guarantee, but it gives you an indication of the approximate relative level of quality between similar sized units.  You should also compare the energy efficiency of each unit.   A more efficient unit can save money in the long run.

The estimate should include the cost of labor which may vary between HVAC contractors, but be sure that the installer will be an experienced HVAC technician. Finally, check to see that the estimate includes clean up and disposal of the old unit.
