What the free tool does before you submit
You can use the HVAC System Check and view a preliminary plan without entering a name, phone number, email address, or creating an account. System answers are sent to our server to calculate your preliminary estimate. This calculation does not create a service request. Selected photo files stay in your browser until you choose to submit the plan.
A result is educational and preliminary. It is not a completed inspection, diagnosis, booked appointment, or fixed proposal.
