Frigidaire FS4BD-KA / KB Central Air Conditioners

Frigidaire FS4BD-KA Air Conditioner Overview

The Frigidaire FS4BD, also known as the FS4BD-KA/KB and the FS4BD-KB, is a high-efficiency air conditioner with an efficiency rating of 13 SEER. Because of regional efficiency standard differences, this unit can only be sold in northern climates. All models have all-aluminum, corrosion-resistant micro-channel coils and a permanently lubricated PSC motor which requires no maintenance. The system is protected by a high-pressure switch with auto-reset and a liquid line filter drier, and a swept-wing fan blade helps keep operating noise as low as 74 decibels. The galvanized steel cabinet has a polyurethane finish with 950-hour salt spray approval for protection against corrosion and weather hazards.

This is another situation I have here. I own Repair Air. I just want you to know these leak refrigerant in the outdoor units. Cheaply made equipment, they all rattle. I was under the impression, according to the warranty, that they guarantee the equipment to be free from defects? The issue I am having here is no one seems to want to make this right for me as the contractor and my customers. I am reaching out to them in my last attempt for a qp replacement. I want to resolve this. They offer a 1 year replacement pledge but I think it's a lie. They don't seem to stand by their product or their so called "dealers". I have a few units that need to be replaced. They all leak refrigerant in the od units! What kind of company is this seriously? This is a joke! In case you're not getting the hint… This is below low grade equipment. If you are a contractor thinking about selling Nordyne equipment, don't! And if you're thinking about purchasing this for your home, do yourself a huge favor! Take it from me, please don't do it either! Read the other reviews. I read them before I wrote this! The people are telling the truth and if you don't believe this then find out for yourself! Good luck! I hope I can help someone here choose reliable comfort!

You know some of these units were good but a few years ago, they had some terrible condensers. One in particular we replaced the entire unit 3 times and changed the compressor once. They had a harmonic problem that caused a leak at the condenser coil distributor. A recurring problem in other units. The local distributor quit handling them. It is a Nordyne, going by the name Philco, Frigidaire, Tappan, Maytag and Gibson. We will never purchase them again. Went simply with Ruud which we almost never have problems. Ended up putting a Ruud in the house we replaced the Nordyne in repeatedly. No problems since.

"Says Model FS4BI-O36K Misery to Get Anybody Who Knows/Wants to Service Them, Thermostat Nightmare, Quiet!"

Very Unsatisfied

Have q drive 23 seer, Nordyne brags about quiet. Yes, since it often does not work, local dealer of Frigidaire will not sell them. Reluctant to service, 7 out of 8 reports saying they are crap. Beware, getting thru Frigidaire and Nordyne people is difficult. I can talk to the pope easier than getting Frigidaire or Nordyne manager to return call. This a.m. after 22-minute hold, back to me by tomorrow company troll said, useless. Thermostat too confusing, definitely overpriced. Lousy support, difficult, expensive to fix. Even if you find someone without manufacturer help. Crap! Crap! Crap! Ask me what I really think. Beware. Recommend to your enemies!
