I posted a few years ago about my Tappan unit. I've owned it almost 5 years now and it breaks at least annually, sometimes more.
It's been 10 months since the repairmen were out addressing a bent fan which they said was causing the unit to freeze up. They replaced the fan. In Texas this time of year, we have a week where you might use the heat and then a couple of days where you use the cooling. It switched to cooling because it was warm outside, and the unit froze up again.
When the heat has been on during the last month or so, it has not been blowing hot air, either. The unit is a 5 ton two-stage unit. I was told it was a 15 SEER unit. It runs constantly and has not saved me any money on electric bills over the 15 year old unit that actually heated and cooled the house.
The company that installed the unit sold me a 10-year parts and labor warranty. Last year when they came out (year 4) the owner said it would be the last time he worked on the unit. Was rude to my my wife as well during the visit. He bought the franchise from the owner that installed the unit, but the repairmen have been the same ones the entire time.
There have been leaks. They've filled the unit on several occassions without fixing the leaks, resulting in repeat visits. The unit at one point was vibrating so badly that an electrical jumper vibrated loose. Was charged $XXX.XX for a guy to come reconnect one jumper (wasn't interested in fixing the vibration, and I didn't pay the bill due to having a warranty for P&L). He was mad that I wouldn't sign up for an annual maintenance contract ($$$). I asked him why I needed annual maintenance since they were at my house every 6, 8, or 10 months anyway fixing a unit that has never run correctly for an extended period of time. And yes, we change the filter regularly (every 1-2 months).
I guess I need some advice and maybe a recommendation of someone who can service Tappan in the Waco, Texas area. I'm guessing that the 10 year parts and labor warranty (still have the paperwork) I bought is worthless and I'll have to eat that money and pay someone who's competent to come repair this unit.
Year 1: coolant leak. 5 visits to "repair" leak. Some trips they simply refilled the coolant and left.
Year 2: would not heat correctly. Basically blowing cold air during the winter. Repairmen came and rigged the system to try and force it to bypass the heat pump and use electric heat. Air from register was room temp, not hot. 3 visits, never really fixed the problem (I paid for a two stage unit, why should it have to be "rigged" to bypass part of the system for which I paid extra?).
Year 3: coolant leak again. 2 visits to repair.
Year 4: Vibration causes jumper to become disconnected. 1 visit, reconnected jumper, left, billed me $XXX.XX.
Year 4: Air conditioner froze up badly. Water everywhere. A/C guys said it was a problem with a bent fan. Replaced fan.
Year 5: has stopped heating effectively and when it switched to AC yesterday, it froze up. Outside temp was 84, thermostat set to 75.
We're just tired of this thing not cooling and heating effectively, costing us a ton of money to run, and having to have someone come out and not correct the problems.
