How to Select the Right HVAC System for Your New Build or Retrofit

Introduction

Choosing the right HVAC system during a new build or retrofit is one of the most important decisions you’ll make as a homeowner. Properly selecting HVAC system options impacts comfort, energy costs, and long-term reliability.


Factors to Consider When Selecting an HVAC System

1. Load Calculations

Manual J calculations determine the exact heating and cooling requirements of your home.

2. Efficiency Ratings

Look at SEER (cooling), EER (energy efficiency ratio), and AFUE (heating efficiency).

3. System Type

  • Central air
  • Heat pumps
  • Ductless mini splits
  • Hybrid systems

4. Fuel Type

Natural gas, electric, or dual-fuel systems.

5. Home Size and Layout

Multi-story homes may require zoning or multiple units.


New Build Considerations

New construction allows freedom to design ductwork, choose equipment, and integrate smart systems from the start.


Retrofit Considerations

Older homes may need ductwork upgrades or specialized systems like ductless mini splits. Retrofitting requires balancing budget with efficiency gains.


Mistakes to Avoid When Selecting an HVAC System

  • Oversizing: Leads to short cycling and wasted energy.
  • Undersizing: System can’t keep up in extreme weather.
  • Ignoring ductwork condition: Leaks reduce efficiency.
  • Choosing lowest price over value: Efficiency saves money long-term.
