of Satisfied Customers

Dana Ray writes:
"Alpine had the best prices, outstanding customer service, a great website, and did a super job of packing the unit for shipping. They used a good shipper, and the unit arrived without a scratch. Alpine also hooked me up with someone to properly reclaim the freon from the old unit and charge the new unit at a very reasonable price. I saved $1,500 over having one of the local A/C contractors sell me one, and I know it's installed correctly because I did it myself. I saved money and got a quiet, efficient scroll compressor. Thanks Alpine!"

Evaporator Coil Orifices

An orifice (also referred to as a piston or flowrater) is installed in an evaporator coil when the coil is a different tonnage rating than the condenser or heat pump tonnage rating. Installation takes about 5 minutes, and consists of replacing orifice already inside coil. We have an online picture step-by-step guide which shows how to do this.

If you are installing a new evaporator coil and can not find manufacturer-specific information for your outdoor air conditioner or heat pump, use this chart as a reference to ensure a properly sized orifice is installed in your system.
