We prioritize you with a dedicated team of HVAC specialists trained to deliver personalized heating and air conditioning replacement solutions tailored to your home and family's needs. Guardian is set apart from the rest with a few detailed steps:
We design around your home, not a model number. We don't just swap out equipment. We create comfort.
Every free furnace estimate starts with a comprehensive home evaluation and duct/airflow check. That means better comfort, quieter operation, and lower utility costs.- We give you options, not ultimatums. You'll see transparent packages—single-stage (value), two-stage (comfort), and variable-speed (top comfort/efficiency)—with AFUE ratings, sound levels, and warranty terms side-by-side.
- We install like we live here (because we do). Sealed and leveled cabinets, correct gas pressures, proper condensate routing, lined flue/venting, and clean electrical. We photograph key steps so you know it's done right.
- We future-proof your system. Whether you're pairing with a new high-efficiency AC (R-32/R-454B era) or a dual-fuel heat pump, we recommend matched components and controls for best performance.
Furnace Replacement: Repair or Replace?
Winter heating emergencies strike without warning, leaving you cold and stressed. We know how critical your comfort is—and how daunting the costs can feel when your HVAC system fails. Serving Kennesaw, Acworth, Dallas, Woodstock, Marietta, Powder Springs, and surrounding areas, we understand that most homeowners aren't ready for sudden replacements. .
At Guardian Home Experts, we don't send pushy salespeople—we send trusted HVAC professionals who understand your system inside and out. We respect that a heater repair or new HVAC investment is major, so we work relentlessly to maximize your value through rebates, financing, cash incentives, and competitive pricing. Ready to explore costs without the guesswork? Take our quick heating and air pricing questionnaire and discover the best HVAC solutions tailored to your budget and needs. Common furnace replacement questions:
How do I know it's time to replace instead of repair?
Consider replacement when the system is 12-20+ years old, needs major parts (heat exchanger, inducer, control board), or struggles to heat evenly. If repair costs are frequent or high, a new furnace often wins on comfort, reliability, and energy savings.
How long does installation take?
Most replacements are completed in one day. Complex duct or electrical upgrades may add time; we'll flag that during your estimate.
Do you replace just the furnace or the whole system?
We'll do what's best for your home and budget. Many homeowners pair a new furnace with a matched AC/coil or heat pump for efficiency, quieter operation, and better warranties.
Will you handle code compliance?
Yes. We install to current code (venting, gas piping, condensate, electrical, clearances).
What brands do you install?
We work with leading manufacturers and match models to your needs—not the other way around. Your options come with clear specs and warranty details. Difference Between HVAC Brands can help you decide.
Do you remove my old furnace and clean up?
Absolutely. We haul away the old unit and leave your mechanical area clean.
Can you help with duct issues or hot/cold rooms?
Yes. We evaluate duct design, return air, and register layout; small duct fixes can make a big comfort difference.
Do you offer financing?
Yes—multiple plans so you can spread the cost comfortably. Your System Design Expert can show monthly payment options during the estimate.
What is your service area?
Guardian has daily routes through Woodstock, Rome, Kennesaw, Acworth, Marietta, Alpharetta, and Cartersville—plus surrounding North Metro Atlanta neighborhoods and everywhere in between.
