Radiant Heating is used in concrete slabs, under sub-floors or above sub-floors.  Radiant Heating offers more flexibility, better aesthetics and comfort.   When used with a Geothermal system, higher efficiencies are achieved.  We offer Rahau, an industry leader, or other manufacturers.

High Pressure Systems are systems that use smaller ductwork, but at a higher pressure. They offer better air distribution and better aesthetics.  These systems are beneficial when a building needs to be heated from only the interior walls or from the ceilings.  The UNICO system is a smart choice.

We install and service all types of heating equipment, including oil, gas and geothermal.  Some of the manufacturers we use are; Slant Fin, Bryant, Vissmann, Comfort Aire, Hydro Delta, Econar, Climate Master, Trane and Carrier.

We also offer wood pellet stoves as a stand-alone heating source or as a supplement to a Geothermal Heating/Cooling system to qualify for a utility’s rebate.


Walk-in coolers/Freezers

Bio-Tough Curbs:

Coolers can be placed on special curbs to protect them from physical damage. These curbs have low bacteria penetration and prevent water collection during wash-down.

Demand Defrost: (as opposed to time clocks)

No need to reset the defrost cycle as the weather and usage changes. Also, reduces energy consumption by 40 % to 80 %, increases available refrigeration system capacity, reduces room hoarfrost, reduces product shock, lengthens equipment life.


Automatic and alternating refrigeration systems that keep you up and running.

Allow time to service; weekdays, not nights and weekends.

Reduces loss of expensive product.

Process Chilled Water Systems/ Ice Storage

Fully automated systems can idle on standby during non-production periods. Ice storage offers off-peak energy use and back-up capacity.

Blast Freezers/Food Process Equipment, including Conveyor Systems

Custom built or standard systems can be fully automated if desired

Solar Water Heating

There are three temperature levels of solar collector design.  The two lower levels are easly intergrated with radiant floor heating and geothermal heat pumps.  This is because to maintain high performance, geothermal heat pumps operate at a lower temperature than oil or gas boilers.

One collector design manufactured here in New Hampshire is installed under the roof.  This design increased the life of the collector and hides it from view.  It is an elegantly simple renewable energy option for building owners, architects and developers concerned with the aesthetics, energy costs and operating budgets of their buildings.  In commercial and industrial applications, the heating or cooling can be used in the manufacturing processes.  

Solar collectors can be used to increase the efficency of the geothermal heat pumps.

The Dawn Solar System (www.dawnsolar.com) is archetecturally intergrated under the metal roof ststem and has a 25 year warranty and can be used for residential, commercial, institutional and industrial applications.

Higher temperature collectors can be used with stroage tanks.  The higher temperature fluid can then be used directly or can supplement the heat pump.
