Size matters more than most people expect with a new furnace. An oversized unit short-cycles, overshoots the thermostat, and wears out early, while a correctly sized furnace runs longer and more quietly and costs less to operate. So Marietta HVAC starts every replacement in Marietta with a load calculation, not the number on the old nameplate. From there, the choices come into focus: 80 percent AFUE or a condensing furnace in the mid-90s, single-stage, two-stage, or modulating burners, and a basic PSC blower or a variable-speed ECM motor that saves electricity and smooths out temperature swings. The right combination depends on your home, your ducts, and how long your heating season lasts, and you will be living with it for the next twenty years.

Warning Signs for Furnace Installation
The sooner you notice these red flags, the easier and cheaper the fix. Here are the most common indicators that it's time to call a professional:
- Uneven heat, frequent cycling, or rooms that stay cold no matter what
- Booming ignition, rust, or soot that keeps coming back after service
- A new air conditioner or heat pump is going in and the old furnace cannot keep up
- A cracked heat exchanger has been found, ending the repair conversation
- Rising energy bills and a home that still feels chilly
- Service calls that come more often and cost more every year
- The blower is loud enough that you plan conversations around it
- Your existing furnace has passed fifteen to twenty years of service
Early Action Saves Money
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. If you notice any of these signs, call (770) 202-3453 for a prompt inspection.
