1. The Home Depot
The Home Depot provides a unique, streamlined approach for homeowners looking to purchase and install a new gas furnace. Unlike manufacturers or local contractors, this big-box retailer acts as a one-stop-shop, offering transparent pricing on equipment from brands like MRCOOL and ROYALTON, paired with a nationwide network of vetted installation professionals. This model is particularly beneficial for those in the greater Atlanta area, from Marietta to Woodstock, who prefer a single point of contact for the entire replacement process.
The platform’s major advantage is its simplicity and upfront cost information. You can browse furnaces online, filter by efficiency (AFUE), heating capacity (BTU), and brand, and see the equipment price directly. For homeowners exploring budget options, you can learn more about HVAC system costs and available financing to better plan your investment.
Key Features and User Experience
The website's interface makes it easy to compare models and read customer reviews before making a decision. You can check real-time store availability for pickup or schedule delivery. When you opt for their installation service, The Home Depot coordinates with a local, licensed contractor in your area, like those serving Kennesaw or Acworth, and backs their work with a one-year workmanship guarantee.
- Pros: Transparent equipment pricing, frequent sales and promotions, and a simplified purchase-plus-installation process.
- Cons: The brand selection is limited primarily to retail-focused brands, and certain high-efficiency models may not be available for shipping to all locations.
2. Lowe’s
Lowe’s presents another excellent big-box retail option for homeowners seeking a new gas furnace, standing as a direct competitor to other home improvement giants. The platform offers a wide catalog of natural gas furnaces from well-known retail brands like Goodman, MRCOOL, and ROYALTON. This model is ideal for homeowners in communities from Roswell to Sandy Plains who prefer to compare equipment online and manage their purchase and installation process directly.
The platform’s key differentiator is its competitive pricing structure, including a prominent Price Match Guarantee and free returns for many items. This allows savvy shoppers to secure the best deal on their chosen unit. By providing detailed product specifications upfront, Lowe’s empowers customers to make an informed decision before committing. Proper upkeep is crucial for any new furnace, and homeowners can learn more about the importance of regular HVAC service to protect their investment.
Key Features and User Experience

3. HVACDirect.com
HVACDirect.com operates as a specialized e-commerce retailer, giving homeowners direct access to an extensive inventory of gas furnaces. This online-first model allows for transparent, upfront pricing on a wide array of brands, making it a compelling choice for those who have already researched the best gas furnace brands and know what they need. For residents in Georgia communities like Canton and Roswell, this platform offers a way to purchase equipment directly and then independently hire a trusted local installer, potentially separating the costs of labor and parts.
The primary advantage of HVACDirect.com is its sheer volume of choice and detailed product information. With hundreds of furnace listings, shoppers can filter by brand, efficiency, and specific configurations. The site also features a helpful sizing calculator that uses your ZIP code, square footage, and home insulation levels to recommend the appropriate BTU capacity, ensuring you find an efficient unit for the climate in areas like Kennesaw or Marietta.
Key Features and User Experience
The website is designed for knowledgeable buyers, offering detailed specifications and verified customer reviews for each model. Its powerful search and filter functions allow you to easily find niche products, such as downflow, multi-position, or low-NOx furnaces that may be harder to source locally. The platform frequently runs sales and even offers scratch-and-dent discounts, providing additional opportunities for savings. However, it is crucial to remember that the buyer is responsible for arranging a licensed, professional installation to keep manufacturer warranties valid.
- Pros: Transparent equipment pricing across a huge selection of models, detailed product filters for niche furnace types, and useful tools like an integrated sizing calculator.

They feature prominent brands like Goodman and Williams, catering to a national audience with robust shipping solutions.
The primary appeal of ACWholesalers lies in its straightforward, equipment-focused shopping experience and aggressive pricing.

This approach is ideal for discerning homeowners in areas like Roswell and Milton who prioritize long-term performance and efficiency over initial upfront cost.
The site’s primary strength lies in its detailed product specifications and educational content. You can explore their entire lineup of gas furnaces, filtering by AFUE ratings that range from 92.1% to a highly efficient 97.3%.
