Heating & cooling, explained

Good comfort starts
with a good plan.

We install conventional furnaces, AC-only systems, hybrid heating, heat pumps, hydro-furnaces and boilers. Different homes need different approaches. Here’s a plain-language look at the choices.

A big part of what we install

Hybrid heating.
Heat pump + furnace.

Electric heating and summer cooling, with fuel-fired heat available when the controls call for it. One plan for the home you already have.

Comfy hybrid and conventional furnace/AC installations include a media air cleaner.

New installations & existing-system replacements

Ducted heat pumps.
Cold-climate options.

All-electric heating and cooling through your vents, with suitable cold-climate systems considered around the home’s load, airflow, electrical capacity, and supplemental-heat plan.

A room, a floor, or a whole-home plan

Mitsubishi Electric
mini-splits

Single-zone systems for one space, or a carefully designed multi-zone layout for a two-story brick rowhome. Closed rooms and separate floors need their own comfort plan.

Inverter heat pumps

Bosch IDS
& furnaces

Ducted heating and cooling with Bosch IDS heat pumps and furnaces. The exact equipment match and distributor availability determine what we can supply.

Conventional forced-air heating

Conventional furnaces.
A fit for your home.

We install conventional furnaces for heating-only projects or matched furnace-and-AC systems, including American Standard furnaces. We have flexibility on equipment brands and choose options around your home, budget, equipment matching and availability.

Conventional furnace/AC installations include a media air cleaner. Exact equipment and installation scope are confirmed during an in-home consultation.

Cooling without a heat-pump conversion

AC-only installation
& replacement

Need summer cooling while keeping suitable existing heat? We install and replace central air conditioning, with the outdoor unit, indoor coil and blower selected as a compatible system.

We check the existing equipment, ductwork, electrical supply and drainage before confirming what can stay.

Fuel-fired heat through your ducts

Navien NPF
hydro-furnaces

A gas-fired furnace that heats water inside the unit, then transfers that heat to the air. It can be part of a properly matched hybrid setup.

Hot-water heating

Navien NFC
high-efficiency boilers

For hydronic heating systems. Current NFC-H combi-boilers combine space heating and household hot water in one wall-hung unit.

Thinking about the budget?

Try an experimental planning range for Mitsubishi mini-splits or a typical hybrid changeout, or choose a conventional furnace or AC-only consultation path. No name, phone number, or email needed.

The house comes first.

A Manual J load calculation considers your home’s heating and cooling needs. Manual S helps match equipment to those loads. For ducted systems, return-air paths, leakage, and airflow matter too.

Square footage alone doesn’t tell us what equipment you need.
