A single-stage high-efficiency furnace burns fuel at one fixed speed—fully on—until your home reaches the temperature you set, then switches off. What makes it “high-efficiency” is the addition of a secondary heat exchanger that captures leftover heat from the exhaust, boosting the system’s overall efficiency to 90% AFUE or higher.

Single-stage high-efficiency furnaces are typically more affordable than two-stage or modulating systems, while still offering better energy savings than a standard single-stage furnace.

It’s a practical choice if you want reliable warmth, decent efficiency, and a lower upfront cost compared to more advanced multi-stage models.

A two-stage high-efficiency furnace adjusts between two levels of heat output—low (for mild days) and high (for those extra-chilly days). Like its single-stage high-efficiency cousin, it also uses a secondary heat exchanger to capture extra heat from exhaust gases, pushing its AFUE rating to 90% or higher.

When mild heating is enough, the furnace runs on the lower setting, using less fuel and creating gentler airflow.

On colder days or when more warmth is needed quickly, the furnace kicks into high gear for extra heat.

A two-stage high-efficiency furnace typically costs a bit more upfront than a single-stage model, but it offers greater comfort control and can use less energy overall. In the long run, you might see lower utility bills and enjoy more consistent heating throughout your home—making it a worthwhile investment for many households.

A two-stage system’s low setting uses less fuel to maintain a consistent temperature, so it doesn’t have to rev up to full blast nearly as often. Over time, this can translate into lower monthly bills—even if the initial purchase price is typically higher.

Upgrading from a single-stage to a two-stage furnace helps keep your home’s temperature more steady and can lower energy bills. That’s because two-stage furnaces usually run on a low setting most of the time, using less energy and creating less noise. They do cost more upfront, but if you value comfort and plan to stay in your home for a while, the benefits can make it worth the investment. Otherwise, a single-stage high-efficiency furnace is still a solid upgrade over older systems.

We currently offer Payne, KeepRite, and Goodman furnaces, and we’re always looking to expand our lineup. However, the exact models we can provide depend on your local availability and what our suppliers have in stock at the time.

Reach out, and we’ll be happy to let you know the best available options for your home.

Payne and Carrier are both produced by the same parent company (Carrier Corporation), so they share a lot of the same engineering and internal components. However, there are some key differences:

Brand Positioning:

• Payne: Positioned as a more budget-friendly option.

• Carrier: Marketed as a premium brand with more features and broader product lines.

Available Features:

• Payne: Offers simpler models and fewer bells and whistles.

• Carrier: Typically offers advanced features like modulating heating, variable-speed blowers, and higher-end control systems.

Price Point:

• Payne: Generally cheaper upfront cost, making it a solid choice if you’re on a tight budget but still want a reliable furnace.

• Carrier: Costs more initially, but you may get more options for efficiency, comfort control, and potentially better long-term energy savings.

1. Warranty & Support:

   • Because both brands share a parent company, their warranties can be quite similar, but Carrier models might include longer or more comprehensive options on certain components.

Ultimately, if you’re looking for a straightforward, dependable furnace at a lower price, Payne is a strong contender.

If you want a high-efficiency system with advanced features and potentially more robust warranty coverage, Carrier is often the go-to choice.

When you’re ready for a new furnace, here’s how the swap-out process typically goes:

1. Disconnect & Remove: First, the old furnace is turned off, disconnected from gas and power, and carefully removed—often including detaching any venting or ductwork. It’s disposed of, leaving you with no hassle and no mess.

2. Prep the Area: Your installation team checks and cleans the spot where the new furnace will go, making sure everything is ready for a smooth setup.

3. New Unit Installation: Next, the new furnace is placed, reconnected to your home’s gas, power, and duct system, and then vented properly.

4. Inspection & Testing: Finally, the technician double-checks connections, fires up the system, and ensures it’s running safely and efficiently. We’ll walk through with you at the end to discuss all the new features, maintenance and items you should be aware of.

You’ll usually have heat again the same day. It’s that straightforward!

Furnace warranties can vary by brand, but most high-efficiency models include a limited lifetime warranty on the heat exchanger and around 10 years on other parts. We register the warranty for the unit on the day of the installation completion and email you all the necessary information and warranty certificate for your records.

At EastHook Heating & Gas, we also provide a 1-year warranty on all labor performed, so you can rest easy knowing your installation or repair is covered.

The cost of a furnace replacement can vary widely depending on the type of furnace, your home’s layout, and any additional components or modifications needed for a proper installation.
