HVAC technician can't do ductwork because of zoning limitations?

There are three pieces to this problem here.

What will the permiting authority accept?

If the inspector says he will approve your renovation without upgrading the existing HVAC system or adding a supplemental unit, then make sure you get that in writing. In my county in Florida, anything renovation that adds roof or that changes the conditioned area by more than 100 square feet requires a new heat loss calculation.

What can you get an HVAC contractor to do?

If they won't do what you want to do, then keep shopping. Considering the size of your job, you'll probably get a better response from a smaller company or an individual HVAC contractor. They are more likely to not dismiss a small job.

Are you prepared to do something more if your current system doesn't work out?

I'm not particularly worried about the system handling the additional load

This could really go either way. If the current space is well insulated and properly ventilated, then that is the...

If your HVAC equipment is the heart of your home, then the ducts make up its circulatory system. Ductwork channels conditioned air to vents, takes return air back into the system and transports exhaust air and waste heat to the exterior of your home. Ducts serve a triple purpose: They carry warmth in winter, hold cool air in summer and provide ventilation for better indoor air quality throughout the year. Because they're in use almost every day, your ducts need occasional maintenance to improve the longevity of your heating and air conditioning equipment.

How Your AC Ducts Work

Unless your home has a ductless system or relies solely on window units for cooling, it has ducts. You probably have a good idea how ducts carry air from the central inside unit of your AC or your heater, but those ducts represent only part of the system. To understand how air moves throughout your home, it's helpful to know about air sources and what your HVAC system does to keep you...

HVAC technicians typically do the following:

Travel to worksites Follow blueprints or other design specifications to install or repair HVAC systems Connect systems to fuel and water supply lines, air ducts, and other components Install electrical wiring and controls and test for proper operation Inspect and maintain customers’ HVAC systems Test individual components to determine necessary repairs Repair or replace worn or defective parts

Heating and air conditioning systems control the temperature, humidity, and overall air quality in homes, businesses, and other buildings. By providing a climate controlled environment, refrigeration systems make it possible to store and transport food, medicine, and other perishable items. Although trained to do all three, HVAC technicians sometimes work strictly with heating, air conditioning, or refrigeration systems. They also may specialize in certain types of HVAC equipment, such as water-based heating systems, solar panels, or...

There are many different types of HVAC Heating, Ventilating and Air Conditioning systems. The purpose of this article is to introduce you to these systems. We will be studying the overall construction and use of these systems. In this article, we will study how each component is used in the system as a whole.

Purpose of HVAC

The purpose of HVAC Heating, Ventilating and Air Conditioning is the control of an enclosed environment. An HVAC system provides adequate indoor air quality by: conditioning the air in the occupied space of a building in order to provide for the comfort of its occupants; diluting and removing contaminants from indoor air through ventilation; and providing proper building pressurization. The three main environmental characteristics that are controlled are:

Temperature Humidity Suspended particulates dust and gas

Temperature

Controlling the temperature of an environment involves the transfer of heat from one area to another....
