Yeah, went with 5280 in the end. I really liked their 10 year labor warranty. Everyone else basically had 2 year. That's correct that with the 80% furnace, they only had to tie into the existing gas flume. Elkhorn was right there in the running, since they also offered Trane and a cash discount. They also only had 2 year labor warranty. The Trane heat pump we went with is 18 SEER / 4 ton. They gave a few bids, with one being a 20 SEER, but didn't think we needed to go that route for the added cost. The furnace is also Trane and has a variable speed ECM.
I had several other companies come out and bid. I was surprised that nobody bid Rheem/Ruud. Got a lot of Goodman, Amana and Lennox. I wasn't interested in any of those for different reasons. I have concerns about Goodman & Amana quality. I heard a lot of "installation is the most important part" but research seemed to find far more negative input on Goodman and Amana as being lower quality/tier compared to Trane. Lennox I had a lot of concerns over prior lawsuits and have heard their parts availability, warranty process and customer service are not great. Front Range bid Bosch heat pump and Amana furnace. I like our Bosch dishwasher and fridge, but I don't know much about their AC.
"Final" cost to us should be about $15,500 after all is said and done with all the rebates. Installer took the $6,100 Xcel rebate and $500 Colorado heat pump rebate directly off the cost. We should be able to get $2k back from the feds on next year's tax return. Ryan (one of the owners) was really helpful and actively involved in the install and did the final checks/certification. There was another main installer who seemed really good and at least one other guy who helped. Install seemed to go really well and looks high quality to me. I'd use them again and recommend them for consideration.
Most of the bids were in a pretty consistent range with brand being the variance. I got one insane bid where the guy said I needed all sorts of duct work in the utility room and wanted $28k. Screw that on multiple levels. I might have been able to chase more bids and/or grind out a slightly better price by continuing the back and forth. I was just kind of over dragging things out. I researched a ton and talked with a lot of people (online and off) to try and make a good decision. Add to that . . . my brother passed away over last weekend, so been dealing with that. Just made the best decision I thought I could make at the time. We should hopefully be set for cooling and heat for a long time.
