Dehumidifiers & Humidity Control

When an older R-410A outdoor condenser fails, replacing the entire HVAC system is not always the only option. If the indoor evaporator coil or air handler is still in usable condition, an A2L refrigerant detection and mitigation kit may allow that indoor equipment to remain in place while the outdoor unit is replaced with a new R-32 or R-454B condenser.

When the outdoor portion of a central air conditioner fails, replacing only that unit can sound like the simplest and least expensive solution. Sometimes it is. However, a central split system is not a collection of interchangeable parts. The outdoor condenser and the indoor evaporator coil work together as one refrigerant circuit, and the combination determines the system's capacity, efficiency, humidity control, reliability, and safety.

Indoor air quality problems like humidity, stale air, dust, and allergens can’t be solved by your HVAC system alone.
