Hello all, I'm a new member here with a repair or replacement decision I'm looking for input on. I have an 11 year old GeoComfort 4 Ton Combination unit that the compressor went out on about 2 weeks ago - short to ground. The GeoComfort warranty was 10 years for the compressor so I'm SOL there. I have been trying to determine to repair or replace. My understanding is because of the way the compressor went out there is a high likely hood of acid in the system and that because this is a combination unit getting the acid completely removed from the system will be difficult if not impossible. I have gotten quotes for both repair the compressor and replace the system. Needless to say I'm very unhappy about the situation as I thought the initial investment would have lasted longer than 10 years! To repair will be approximately $3.7K with a 1 year compressor warranty and 30 labor warranty. Different dealers have stated concerns with repairing a combination unit compressor based on the way that it failed. The option to replace is a bit more interesting. The dealer is not recommending to replace with a Combo unit again (sounds like lessons learned over time) and is recommending repalcimng with a Water to Water w/ and hydronic air handler - GeoComfort 4 Ton unit. It would use my existing buffer tank. I understand there may be limitations to this during the time of the year when cooling/heating may both be desired (late spring/early fall). The replacement cost is ~$19K (after leaning on GC, was $20K+. This would come w/ a 10 year + 8 year compressor parts only warranty. With the current 26% tax credit, that brings it closer to $14K. I also have a quote for a GC and WF combo units which are around $15k and $17k but I'm not sure I want to go through this hassle again with a combination unit if they aren't built to last. For both GC options, there is an additional option of $1.2K to hook up a storage tank option for the DSH. The current combo unit had a DSH that was hooked up direct to a Marathon hot water heater, but no storage tank. Also, the DSH pump failed about 3-4 months prior as it got a cracked fitting and leaked water into the bottom of the unit but was caught within hours of occurrence but hasn't been fixed due to distance from dealer. Questions I'm looking for input on.... 1. Repair or Replace - reasons? 2. If replace, Another combo unit or a water/water with air handler? Why? 3. Is the DSH w/ a storage tank worth the extra cost? 4. Any other options I should be looking at or investigating? Frankly, I have a sour taste in my mouth with GeoComfort right now based on the problems with the current one (compressor, DSH, previous board issues) and a lack of significant compensation for a replacement.
