Once you ve completed installing a new air conditioner your work isn t quite finished.
Split system hvac condensate line roof unit.
Ashrae standard 90 1 2010 section 6 4 4 1 hvac system pipe insulation lists hvac piping requirements and as an exception excludes from that requirement piping that conveys fluids that have not been heated or cooled through the use of fossil fuels or electricity such as roof and condensate drains domestic cold water supply and natural gas.
These drain lines carry away condensation produced by the operation of the evaporator on the air conditioner unit.
How to choose the right system.
Before you switch on the unit you ll need to know the proper way to install a condensate drain line.
And in whole house terms if you replace your existing central heating cooling system with a complete ductless solution you may pay two to three times the cost of simply replacing.
A condensate drain hose should always include an inline waterless drain trap which is now mandated by the imc section m307 2 4 1 ductless mini split system traps.
Alltek mini split air conditioner bracket outdoor wall mounted heavy duty bracket for outdoor ductless ac heat pumps condenser units 9000 36000 btu 440 lbs by alltek 47 95 47.
Its job is to efficiently funnel condensation away from your hvac unit.
This includes rooftop.
Enter the condensate line which essentially functions as a drain line.
Imc 307 2 3 states that all hvac equipment that produces condensate must have either a secondary drain line or a condensate overflow switch a secondary drain pan with a secondary drain line or condensate switch or some combination of these installations should be used to prevent overflow if the primary drain line blocks.
Ductless mini split equipment that produces condensate shall be provided with an inline check valve located in the drain line or a trap.
Cracks crevices and bad ductwork are just a few of the host of problems that can happen with split systems.
It connects directly to the hvac unit and leads outdoors often through an exterior wall.
Excessive condensation from air conditioning is a sign you have an ac issue.
Our photo left shows the condensate drain termination for a roof mounted split system air conditioner the white plastic condensate drain exits the building wall and is carried to the roof surface next to the roof mounted inverter or compressor condenser unit for the cooling system.
Choosing the right type of central air and heating hvac system is based on a number of factors.
For a single room solution ductless units cost several times more than comparable window units or baseboard heating units thousands of dollars versus hundreds.
