The right heat pump starts with the right design.

Designed for your home. Installed by one team. Rebates handled for you.

We don't start by recommending equipment. We start by understanding your home.

Every installation begins with a Project Design Visit, not a sales visit. Before recommending a heat pump system, we evaluate how your home performs, your existing heating system, ductwork, electrical capacity, and comfort goals. Then we design the right solution, identify every rebate, financing, and Turnkey opportunity available, and manage your project from design through installation with one accountable team.

Why homeowners choose Souzet

Design comes first.

Most contractors start by recommending equipment. We don't.

The way your home loses heat, the way air moves through it, the existing ductwork, the electrical system, and your comfort goals all influence which heat pump system makes the most sense.

That's why every project begins with a Project Design Visit.

Instead of selling equipment first, we design the right solution for your home. Then our team manages everything that follows, including installation, rebates, financing, and Turnkey services when available.

No guesswork.
No oversized equipment.
No unnecessary upgrades.
Just the right system for your home.

You may qualify for a no-cost heat pump system.

Through Turnkey Services offered by the Sponsors of Mass Save®, qualifying moderate-income households may receive significantly enhanced incentives for home electrification projects.

How we design your system.

A heat pump can distribute heating and cooling through existing ductwork, newly installed ducts, ductless indoor units, or a combination of systems. Every system we install begins with a Project Design Visit to determine which solution best fits your home.

Ducted Heat Pumps

Whole-home comfort using existing or newly designed ductwork. One system for heating, cooling, and dehumidification.

Ductless Mini-Splits

Room-by-room comfort without ductwork. Ideal for additions, older homes, and spaces where ducts aren't practical.

Heat Pump Water Heaters

An energy-efficient replacement for traditional electric water heaters. Eligible homes may also qualify for rebates.

Retrofits & System Replacements

Whether we're converting an existing system or designing a completely new one, every project begins with understanding your home.

Every home is different. So is every heat pump system.

The best heat pump system isn't determined by the equipment. It's determined by your home.

Some homes already have ductwork that can be reused. Others perform better with ductless mini-splits. Some benefit from a combination of both. During your Project Design Visit, we evaluate how your home is built before recommending the right solution.

My home already has ductwork.

Many homes can transition from a furnace and central air conditioner to a ducted heat pump while keeping existing ductwork.

We evaluate the condition, size, and layout of your ducts to determine whether they can be reused or should be modified for better comfort and efficiency.

My home doesn't have ductwork.

A home without ducts doesn't automatically mean mini-splits are the only option.

Depending on your home's layout and construction, we may recommend ductless mini-splits, a newly designed ducted system, or a combination of both. Every recommendation starts with understanding your home.

My home has a little of both.

Some homes already have ductwork in part of the house while other areas have none.

A hybrid system combines ducted and ductless heat pumps into one coordinated solution, delivering comfort where it's needed without forcing every room into the same design.

Understanding heat pumps starts here.

Distribution options

Ducted vs. ductless heat pumps

One of the biggest misconceptions is that every heat pump is a mini-split. In reality, a mini-split is just one type of heat pump. Heat pumps can distribute heating and cooling through ductwork, ductless indoor units, or a combination of both.

The right solution depends on your home, not just the equipment.

Ducted Conversion

Can your existing ducts be used?

Many homes can transition from a furnace to a ducted heat pump while keeping their existing ductwork. However, the answer isn't always yes.

A heat pump moves air differently than a traditional furnace. Ductwork that worked well for an older heating system may not deliver the airflow a heat pump needs to operate efficiently. In other homes, the ducts may be undersized, poorly designed, leaking air, or simply worn out after years of use.

That's why we never assume existing ductwork can be reused.

During your Project Design Visit, we evaluate the condition, layout, and airflow of your duct system before recommending a ducted conversion. Sometimes the best solution is to keep the existing ducts. Sometimes they need modifications. In other cases, a different distribution system delivers better comfort and performance.

The right answer depends on your home, not on a one-size-fits-all approach.

Duct Retrofit

Can ductwork be added to an existing home?

Many homeowners believe that if a home doesn't already have ductwork, a ducted heat pump isn't an option. In many cases, that's not true.

Existing homes can often be retrofitted with new ductwork. The feasibility depends on factors such as the home's layout, attic or basement access, ceiling height, structural framing, and available space to route the ducts. Every home presents different opportunities and limitations.

That's why we don't recommend ducted or ductless systems before evaluating the home.

During your Project Design Visit, we assess how your home is built and determine whether adding ductwork makes sense. In some homes, a new duct system provides the best long-term comfort and appearance. In others, ductless mini-splits or a hybrid system may be the better solution.

The right answer depends on your home, not on a standard installation approach.

Weatherize first. Then design the right heat pump.

The most efficient heat pump starts with an efficient home.

Air sealing and insulation reduce the amount of heat your home loses during the winter and gains during the summer. That often allows for a smaller, more efficient heat pump system, improving comfort while reducing installation costs and long-term energy use.

When appropriate, our Insulation Division completes weatherization before heat pump installation, helping your system perform the way it was designed to.

Why the order matters

  1. A better-insulated home loses less heat.
  2. A home that loses less heat often requires a smaller heat pump.
  3. A properly sized system is more comfortable, operates more efficiently, and costs less to run over time.

That's why we evaluate the entire home before recommending equipment.

One team. One design. One accountable partner.

A heat pump project usually means juggling a salesperson, a designer, an installer, an electrician, and a rebate processor, each pointing at the other when something slips. At Souzet, they're the same team.

No subcontractor maze

Design, installation, electrical coordination, and rebate paperwork under one roof. You always know who to call, and it's us.

Designed and installed by the same people

The team that studies your home is the team accountable for how the system performs afterward.

Rebate specialists

We work with these programs every day and confirm every rebate, financing option, and Turnkey pathway before any work begins.
