Ductless Heat Pumps

Ductless Heat Pumps are now a realistic option for any home or office, in any climate. Residential and commercial systems offer year-round, high efficiency heating and cooling for a variety of rooms. A variety of indoor units provide zone comfort control and higher efficiency with minimal power usage.

Ductless Split Systems are best used in schools, homes, offices, restaurants, and churches. Duct-free systems can be installed in places where conventional ducted systems cannot go, or are an ideal complement to your ducted system.

We are a leader in Denver and have attained Diamond Dealer and Diamond Designer level certifications from the world’s premier manufacturer of Ductless Mini split systems – Mitsubishi Electric.

The Mitsubishi Ductless Mini split systems locates the compressor and condenser outside the home or business eliminating the need for basement or attic-located evaporator units and bulky ductwork.

High Velocity Cooling (Central Cooling)

The basic difference between high velocity cooling (brand names Unico or SpacePak) and other air conditioning systems is the way it actively circulates air within the room of your home and throughout the structure’s entire living/working space.

Circulating the air more effectively is what makes a home with SpacePak central air so uniformly comfortable: no cold or warm spots, no drafts, and up to 30% more humidity removed.

Conventional central air conditioning in Denver can drop cold air in at the ceiling; the distribution of cool air is haphazard, leading to over-cooling in some spots or drafts in others.
Central Air Built Around the Space You Have… or Want

High velocity can be installed into either new construction or an existing structure. Either way, the simplicity of sized-to-fit tubular ducts requires just a fraction of the installation time and cost associated with having sheet metal ductwork fabricated and installed.

High Velocity Cooling is Best Suited for:

  • Historic buildings
  • Buildings without existing ductwork
  • Buildings that utilize radiant heat systems
  • Open floor plans
  • Log homes/cabins
  • Brownstones or row houses
  • Lofts
  • Additions
  • Modular homes

Evaporative Coolers (Swamp Coolers)

Pasterkamp has several options and manufacturers available for your evaporative cooler (swamp cooler) needs for your home or business.

In low-humidity areas such as Denver, evaporating water into the air provides a natural and energy-efficient means of cooling. Evaporative coolers, rely on this principle, cooling outdoor air by passing it over water-saturated pads, causing the water to evaporate into it. The 15° – 40°F-cooler air is then directed into the home, and pushes warmer air out through open windows or ceiling vents.

Installation and operating costs can be lower than that of a conventional air conditioning system.

A Pasterkamp Pro will be happy to educate you on the merits and applicability of an Evaporative Cooling System for your home or business.

When it comes to your air conditioning and cooling needs – Pasterkamp can handle that!
