Frequently Asked Questions


1: Who is in charge of the Residential HVAC Permit?

Once you have all of your required submittal forms and design data, then this is the time to submit for your permit.The home owner is the initial person for submitting for the permit unless they have assigned this responsibility to the builder or general contractor

3: Is the age of a home important?

The age of the home is a factor when determining the requirements of the design and system to be installed.

4: Does home insulation matter?

Insulation in a home is a major factor when design a system and selecting the equipment as you may have an abundance of air infiltration

5: Are windows and doors important?

Properly installed windows and doors will prevent air leakage and infiltration. Older single pane windows are a very poor barrier to these factors.

6: Can existing ducts be kept in some areas?

Yes. In some cases where the ducts are not accessible to be changed, we can incorporate other ducts or possibly just use the ducts that are existing.

7: How can we avoid bulk heads?

Depending on what you are looking for in a finished home, sometimes bulkheads cannot be avoided. However, we work with the house designer and builder to try and hide these as much as possible by having the risers behind cabinets or in closets, and having the bulkheads in coffered ceilings.

8: Will each area of the house have proper ventilation?

When properly designed, every room will be properly ventilated with supply and return air

9: What do Heat Loss and Heat Gain mean?

Your “heat loss” is the amount of heat loss through the building envelope and the “heat gain” is the amount of heat absorbed by the building envelope.

10: How much will the Residential HVAC Permit cost?

Each municipality will have their own cost breakdown for different permits. This information is readily available on their web sites or by calling the building department.

11: How does payment work?

Payment for the design of your HVAC system is made prior to our office releasing the submittal package. This is common practice and prevents any fraudulent use of the package. We now accept E-transfer payments.
