Are There Hidden Charges in Your HVAC Estimate?

Upgrading your old forced air heating or air conditioning system is a good way to increase the value of your home and improve its energy efficiency. Unfortunately, it could also set you back a pretty penny. so it’s understandable to want to maximize the value of your investment as well as guarantee that you’re getting your money’s worth.

Unexpected delays and charges are a normal part of any installation job. This is as true in other industries as it is in the HVAC industry.  Unfortunately, this can often catch homeowners off guard, especially those who have no experience with HVAC installations and replacements.  Here the HVAC specialists at OK Heating give you a few tips on how to avoid these surprise hidden charges.

The Biggest Culprit

Hidden charges aren’t necessarily a scam. More often than not, they’re the result of the need for additional work. which was only discovered over the course of repairing your heating and air conditioning system. The most common culprit behind these hidden charges is your ductwork. Any leaks, scratches, dents or other damage to your duct network can impact the performance of your HVAC system, and thus must be repaired as soon as possible.

Wall Damage and Modifications

It’s not uncommon for HVAC work to extend to your walls. Putting up ducts might involve cutting through the drywall or expanding the space between the boards. This, of course, will likely incur additional costs that might not be included in your original estimate. Make sure to talk to your contractor about any changes they may need to make to your wall before the work begins.


The electrical systems of some homes may not be powerful enough to handle the load of a newer air conditioning unit. This is usually the case for older homes. If this happens, the wiring system must be upgraded before the HVAC system can be put into place. Double-check with your technician to determine whether or not your current electrical system can take on the added demand.
