Complete HVAC System Replacement

Replace the main components of an existing heating and cooling system together with a complete HVAC system replacement package from Public HVAC Solutions. These services cover replacement of the furnace, indoor evaporator coil, and outdoor AC condenser when all three components need to be updated. Packages are organized by furnace capacity, while the equipment itself is selected separately based on the home's requirements and the existing HVAC system. Review the individual service listing carefully to confirm the scope of work before ordering.

Complete Heating and Cooling System Replacement Packages

A complete HVAC system replacement combines work that would otherwise require several individual replacement services. Instead of replacing only the furnace or only the cooling equipment, the furnace, evaporator coil, and condenser are handled as one project.

The service options on this page are organized by furnace BTU capacity. Furnace size is only one part of choosing equipment, though. The cooling side also needs a properly sized condenser and evaporator coil, and the components need to be compatible with one another.

These packages are intended for replacement projects where much of the existing HVAC infrastructure is already in place. Individual listings should be reviewed for details involving existing ductwork, gas service, drain connections, furnace venting, and other site conditions.

Furnace, Evaporator Coil, and AC Condenser Replacement

Each component in a complete heating and cooling system replacement has a different job. The furnace provides heat and moves conditioned air through the duct system. The evaporator coil is the indoor part of the air conditioning system, while the AC condenser is the outdoor unit connected to the coil through the refrigerant circuit.

Replacing the indoor coil and outdoor condenser together also gives you the opportunity to select cooling equipment as a matched combination rather than assuming a new outdoor unit will work properly with an older indoor coil.

A full system replacement is not always necessary. If the furnace is still in good condition, an AC condenser and coil replacement may be a better fit. If the outdoor condenser does not need to be replaced, Public HVAC Solutions also offers furnace and coil replacement services.

What to Check Before Replacing the Complete HVAC System

Replacing all three components at once does not mean that every furnace, coil, and condenser combination will work for the property. Equipment still needs to be selected based on the home's heating and cooling requirements and the existing installation.

• Heating capacity: Furnace BTU input and output should be appropriate for the home's heating load rather than chosen only because they match the old furnace.
• Cooling capacity: Condenser and evaporator coil sizing should match the cooling needs of the property and the approved equipment combination.
• Furnace efficiency and venting: Furnace efficiency can affect venting requirements, so the existing setup needs to work with the replacement furnace.
• System compatibility: The condenser, evaporator coil, furnace blower, and related components need to work together.
• Refrigerant: The indoor and outdoor cooling components must be compatible with the refrigerant specified for the system.
• Existing infrastructure: Check ductwork, gas lines, drains, electrical service, refrigerant piping, and available equipment space before installation.

A qualified HVAC professional should confirm heating and cooling loads, equipment compatibility, and installation requirements before the new system is selected.

When a Full HVAC System Replacement Makes Sense

Replacing the furnace, evaporator coil, and condenser together may make sense when several major components are aging, both the heating and cooling systems need work, or older equipment is being replaced with components that need to operate together as a matched system.

That does not mean every project needs a complete replacement. If one part of the existing system is still suitable, replacing only the components that need attention may be more practical. Looking at the age, condition, repair history, and compatibility of the existing equipment can help determine the appropriate scope of the project.

Public HVAC Solutions offers complete replacement packages as well as individual and combination services, making it easier to choose the level of work that fits the actual condition of the system.

HVAC Equipment and Nationwide Shipping

The prices shown for Public HVAC Solutions replacement services cover labor and do not include the equipment itself. Customers can shop HVAC equipment separately and select components that match the requirements of the replacement project.

Public HVAC Solutions ships HVAC equipment across the United States and Canada. Inventory, models, capacities, refrigerants, and equipment configurations can change, so check each product listing for current specifications and availability.

Because these packages involve both equipment selection and installation labor, confirm the service requirements and project details before ordering.

Complete HVAC System Replacement FAQs

Does a complete HVAC system replacement include new ductwork?

Not under the standard package descriptions shown in this category. These packages are intended for replacement projects where much of the existing HVAC infrastructure is already in place. That can include ductwork, gas lines, drain connections, and furnace venting. If any of those items need to be repaired, modified, or replaced, the additional work should be identified before the project begins. Existing ductwork should also be checked to make sure it is suitable for the replacement equipment.

Should the furnace and air conditioner always be replaced at the same time?

No. Replacing them together may be worthwhile when both systems are aging, several major components need repairs, or the new cooling equipment needs to be paired with compatible indoor equipment. A working furnace does not automatically need to be replaced because the air conditioner fails, and the same is true in reverse. The age, condition, repair history, compatibility, and expected remaining life of each component should be considered before deciding on a full HVAC system replacement.

How is a replacement HVAC system properly sized?

Replacement equipment should not be selected simply by matching the BTU rating or cooling tonnage of the old system. Heating and cooling loads depend on factors such as the size and construction of the home, insulation, windows, orientation, and local climate. Furnace capacity and air conditioning capacity also need to be evaluated separately. A qualified HVAC professional can calculate the property's heating and cooling needs and confirm that the furnace, evaporator coil, condenser, and airflow requirements work together.
