We never know when we’ll be hit by that intense triple-digit heat during the summer.  You don’t have to worry about reliable air conditioning with Pederson HVAC’s help!  Pederson HVAC is your family-owned and operated heating and cooling company. We know how important air conditioning is to your family’s comfort and health.  In fact, the HVAC system should be a major factor for those looking to purchase a home since reliable and efficient heating and cooling systems are critical to being comfortable.


Mini-splits are heating and cooling systems that allow you to control the temperatures in individual rooms or spaces.

Mini-split systems have two main components — an outdoor compressor/condenser and an indoor air-handling unit(s) (evaporator). They are easy to install usually requiring only a three-inch hole through a wall for the conduit; which houses the power and communication cables, copper tubing, and a condensation drain line, linking the outdoor and indoor units.

Mini-split heat pumps are not only great solutions for whole home or new constructions but make good retrofit add-ons to houses with “non-ducted” heating systems, such as hydronic (hot water heat), radiant panels, and space heaters (wood, kerosene, propane). They can also be a good choice for room additions where extending or installing distribution ductwork is not feasible, and energy efficient new homes that require only a small space conditioning system.
