Timothy Redmond founded Redmond HVAC in 1987 after working many years in the Heating, Ventilation, Air Conditioning and Refrigeration (HVAC) field.  We are a full-service company offering high quality equipment. All of our systems are designed using the most up-to-date engineering software for both heating and cooling load calculations, along with duct work sizing and layout. We are continuously involved in meeting the needs of our customers—both new and existing.

Redmond HVAC offers a full range of services for residential and commercial applications, including:

• Sales, Installation and Follow-Up Service
• GeoExchange Heat Pump Systems
• Mitsubishi Air-Source Heat Pump Systems
• Solar Hot Water Systems

We care about your comfort. With every GeoExchange system installed by Redmond HVAC, you will find that extra something—a humidification system for those dry winter months, and a high efficiency air filtration system that cleans the re-circulated air in your home.

High Efficiency Oil & Gas Heating & Cooling

High efficiency heating and cooling systems are designed to provide more comfort, better indoor air quality, quieter operation, and increased fuel savings. Whether you are building a new home or wish to upgrade your current equipment, Redmond HVAC will work with your to customize the right system to fulfill your heating and cooling needs.

Types of Geothermal Heat Pump Systems

There are four basic types of ground loop systems. Three of these — horizontal, vertical, and pond/lake — are closed-loop systems. The fourth type of system is the open-loop option. Which one of these is best depends on the climate, soil conditions, available land, and local installation costs at the site. All of these approaches can be used for residential and commercial building applications.

Closed-Loop Systems

Most closed-loop geothermal heat pumps circulate an antifreeze solution through a closed loop — usually made of plastic tubing — that is buried in the ground or submerged in water. A heat exchanger transfers heat between the refrigerant in the heat pump and the antifreeze solution in the closed loop. The loop can be in a horizontal, vertical, or pond/lake configuration.  One variant of this approach, called direct exchange, does not use a heat exchanger and instead pumps the refrigerant through copper tubing that is buried in the ground in a horizontal or vertical configuration. Direct exchange systems require a larger compressor and work best in moist soils (sometimes requiring additional irrigation to keep the soil moist), but you should avoid installing in soils corrosive to the copper tubing. Because these systems circulate refrigerant through the ground, local environmental regulations may prohibit their use in some locations.

Geothermal Systems

Geothermal solutions use the constant temperature found just below the ground’s surface to supply heat pumps with an energy source for heating or cooling.
