Hi, I am a Building Science student, working on a residential HVAC research project. Specifically, I am comparing the following types of systems in terms of energy usage, initial cost, maintenance cost, and lifespan, to determine the payback due to energy savings in several climates:Furnace & A/C split system (high, medium and low eff)Heat PumpMini-SplitGeothermal Heat PumpRadiant heating and coolingEvaporative coolingI have modeled these systems in a sample production home in an energy modeling software. I need some help estimating the upfront cost. Of course, I am not looking for itemized hard quotes, just a rough estimate of the parts plus labor. The systems are not going to be installed, I am only using the data in a model. I have already sized the equipment and have a estimate on the ducts (where applicable). I have been looking at Lennox and Carrier for the split systems, but I can use another brand if it is more convenient to price.If anyone is able to help me with this, I would be very grateful. I would be happy to share the results as well. I can send the specific model numbers on this thread or via email. my email is burketthw@appstate.edu.Thanks!See More
