First let me thank all of you for helping us out over the past two years. We have decided to no longer sink money into our current 12 + years old a/c and heating system and go with something new and better. Following are my questions:
We received 3 proposals from 3 different companies. Only one of them came to our home and spent 1 1/2 hours examining all duct work, inside unit and outdoor unit and measured the entire home including 2 walk in closets and laundry room. They then gave us a proposal stating that our 3 ton condenser was undersized. I first asked them for our sq. footage and they came back with 1,930. We were shocked because the builder told us it was 1,666. We did, however, purchase an option that gave us a loft with skylights and I'm not sure if the 1,666 was with or without that attic conversion. If it was not include it bring the sq. foot up to maybe 1,860. Do you think a 3 ton was too small even at the higher loft calculation? Our home is two story, open floor plan.
Questions 2: The other proposals that were given to us were prepared without doing load calculations. One company said they didn't need to do it (we are not doing business with them) and the second company told me if we decide to do business with them, they will come in and do the load calculation. I asked this particular company how they can make a recommendation without doing the load calculation first and they said because they did all the original installation for our builder (which they did). However, the builder did try to cut corners and as I said the original 3 ton may have been determined before they offered the loft option.
Question 3: We have called numerous companies to look at our current configuration to get a proposal. We insisted on them doing load calculations and 99.9% said they don't need to as they will just replace with the same size we have now.
What gives??????? Is this the way its supposed to be? Load calculation "after" you sign a contract? How can any of them make an accurate recommendation? Can you please tell me how to handle this and what the proper procedure is?
BTW, I have asked the company that did the load calculation and their recommendation for a 4 ton condenser vs our current 3 ton, for back up documentation that supports their recommendation as I have to present it to The Board of Directors of our Association for approval. (I just asked for it this morning and have not received a reply).
Thanks so much
