Choosing The Right System

There are 4 types of HVAC Systems available for mobile vehicle applications: The Key System, The Tie-in System, Engine Driven Independent Systems, and Generator Driven Independent Systems. It’s important to know which ones are the right fit for your vehicle and needs. 

The Key System: The key on engine-driven independent system and the key off-engine off independent system. The key off-engine off system requires plug-in land power, a generator, battery bank with charging system, solar panels, or an engine driven auxiliary alternator.

The Tie-in System: Tie-In systems are the most widely used system of all and are also one of the most economical to run and install. Tie-in systems tie into your existing A/C and heating system utilizing the reserve capacity that the  factory system has build in. they add a secondary Evaporator core and Heater core with fan assembly into the interior of the vehicle which ties into the existing A/C compressor and condenser unit for their operation where as the heater is fed hot water from the engine block via and add on pump unit. Tie-in systems are a great option but they do have their imitations. The vehicle needs to be insulated because they only have so much cooling capacity ( usually around 12,000 -18,000 BTU) and they will struggle to cool the vehicle in high humidity conditions. (60% and above)

Engine Driven Independent Systems: Key on, independent systems are a standalone system that utilizes its own engine driven A/C compressor and compressor mounting system. they have their own condenser may it be under body mounted or roof top mounted along with an add on Evaporator core with fan assembly. The evaporator may be a secondary interior mounted unit or be integrated into the roof top mounted Condenser unit. These systems typically use the engine’s hot water supply to run the heating aspects of the system if the heating options are utilized. These systems can easily achieve upwards of 60,000 BTU and have no problems keeping up with requirements of any environmental condition.

Generator Driven Independent Systems: These systems work similar to what you would find on a typical RV except they are made of higher quality components for the continuous duty applications of commercial use. They require mounting of a generator unit or land power to run them. They require additional ceiling and roof reinforcement to support the added weight and along with a hole cut in the roof they require dedicated wiring circuits. These systems average between 10,000 to 15,000 BTU of cooling and some offer the Heat pump option but mostly use an electric heat strip for their Heating. These systems can be a great alternative to leaving your engine running all the time.
