This proposal outlines a highly cost-effective solution to introduce heating and cooling into your basement workout room.

As we discussed, creating a "true" independent heating zone for this space using your newly installed Lennox system is not feasible. The workout room is not large enough to handle the minimum required airflow for the main furnace; attempting to restrict the airflow to just that room would cause high static pressure and permanently damage your new Lennox equipment.

While the ultimate solution for independent comfort would be a dedicated single-zone ductless mini-split (typically a $6,000–$7,000 investment), we have designed an alternative approach. By tapping directly into the existing ductwork that runs through the ceiling of the workout room, we can provide excellent supplemental comfort to the space whenever the main house is calling for heating or cooling.

With your current oil boiler requiring more frequent service, this proposal outlines a premium, high-efficiency upgrade path to give you ultimate peace of mind and significantly lower your annual heating costs.

Instead of installing another heavy, standard cast iron boiler that wastes energy keeping itself hot in the mechanical room, we will upgrade your home to the Energy Kinetics System 2000. This advanced system utilizes a low-mass, spiral heat exchanger that rapidly transfers heat directly to your home. While this proposal configures the system for single-zone "heat only", it will still drastically cut down your annual fuel consumption while providing exceptionally quiet operation.

Scope of Work

1. Demolition & System Decommissioning

Following our recent service visit where we discovered high carbon monoxide (CO) readings and had to red-tag your 31-year-old furnace, this proposal outlines the complete modernization of your home's heating and cooling infrastructure.

The Hybrid Strategy (Dual-Fuel):
We know your primary goal is to be energy-conscious and electrify your home as much as possible. However, based on our load calculations, an electric heat pump alone will not have the capacity to keep up with your home's heat loss on the coldest winter days. To give you the best of both worlds, we have designed a Lennox Hybrid System.

This system pairs the top-tier Lennox SLP99 Modulating Gas Furnace with the ultra-efficient Lennox EL21KLV Cold-Climate Heat Pump. The system uses your "Thermal Balance Point" to maximize efficiency: during milder winter weather, it uses the highly efficient electric heat pump. The moment the temperature drops to the point where the heat pump can no longer keep up, the system's "brain" aut

This proposal outlines the direct replacement of your aging Energy Kinetics EK-1 system. Because you already know and love the efficiency of the System 2000, we will be upgrading you to the modern equivalent: the brand-new Energy Kinetics EK-1 "Frontier" boiler.

Additionally, we noted that your current hot water storage tank was replaced back in 2021. Because these tanks typically carry a 6-year warranty, it is quickly approaching the end of its guaranteed lifespan. Instead of waiting for it to fail a few years down the road, we highly recommend proactively replacing it now alongside the boiler. This ensures your entire mechanical room is 100% brand new, giving you total peace of mind and zero worries for years to come.

Our team undertook a comprehensive upgrade of your home's heating and cooling system. After a detailed load calculation, we identified significant inefficiencies in your current oil/wood furnace and outdated ductwork. To enhance comfort and performance, we removed the old "octopus-style" ductwork and installed a new, efficient "trunk and branch" design. Additionally, we replaced the bulky equipment with a high-efficiency Lennox Hybrid system, combining a gas furnace and an electric heat pump. This new system is more compact and offers superior, quiet operation.

Barrington, NH - We modified and extended the existing furnace ductwork to support your kitchen and mudroom renovations. This involved adapting and replacing a main supply trunk, ensuring proper reincorporation of existing duct runs. The trunk line to the mudroom was upsized to a 10" x 8" duct for adequate airflow. A transition to an 8" x 8" duct was made for foundation penetration, with a 10" x 10" cut planned on site. This work addressed heating gaps and ensured proper airflow to the new spaces.

Since your home currently utilizes forced hot water baseboard for heating, adding traditional central air can be a challenge. To provide you with the most comfortable, cost-effective, and aesthetically pleasing solution, we have designed a "hybrid" Mitsubishi cooling system.

This design utilizes a ductless wall-mounted head for the open-concept first floor and a fully ducted Mitsubishi Air Handler to properly condition the second-floor bedrooms. This hybrid approach minimizes the amount of equipment needed, significantly reduces the project investment, and provides incredibly consistent, even airflow throughout the entire home.

This proposal outlines the installation of a comprehensive, whole-house 5-zone mini-split system. We will be installing a standard high-efficiency heat pump system (non-Hyper Heat). This system is designed to provide phenomenal, whisper-quiet air conditioning throughout the entire home during the summer, as well as highly efficient supplemental heating during the cooler fall and spring "shoulder" seasons.

Scope of Work

1. Outdoor Equipment

Condenser Location: We will install the new 5-zone outdoor heat pump unit on the gable end of the home, positioned on the backyard side of the fence as discussed.

Electrical: A new dedicated 240V high-voltage circuit will be run to the outdoor unit. To create the necessary space in your electrical panel, we will safely remove the two existing, unused circuits (currently turned off) that Jeff pointed out during our visit. That space will be repurposed for the new single 240V breaker. (Note: The existing 120V service receptacle is within the code-r

This proposal focuses on the cooling and air-distribution side of your home's comfort system. We will be completely replacing the three aging hydro-air handlers (First Floor, Second Floor, and Third Floor/Attic) and their corresponding outdoor AC condensers. Due to the enclosed locations of the upper-floor air handlers, we will be utilizing an advanced chemical flush process to perfectly clean and reuse your existing copper refrigerant lines, ensuring your home's drywall remains completely untouched.

Scope of Work

1. Indoor Hydro-Air Handlers (AHU 1, 2, & 3)

Equipment: We will supply and install three (3) new First Co. Hydro-Air Handlers, carefully maneuvering them into their respective mechanical spaces (Basement, 3rd-Floor Closet, and Attic).

This proposal outlines the comprehensive modernization of both your second and third-floor HVAC systems. By electing to complete both of these installations simultaneously, our team is able to consolidate our labor, particularly when running the new refrigerant line sets for both systems at the exact same time. This streamlined, single-visit efficiency allows us to pass significant labor savings directly back to you!

For the Second Floor, we will replace the aging equipment with a modern, high-efficiency gas furnace and AC system that seamlessly ties into your existing ductwork.

For the Third Floor, we will upgrade the failing system to a premium, 100% electric Mitsubishi Heat Pump. Because of the square footage of this space, this is a much more cost-effective investment that guarantees robust heating even in sub-zero temperatures, allowing us to safely cap off the gas line for this zone.
