Comments (8)Really depends on the construction and that is where the manual J comes in. You have some real heat gains with a 2 story & lots of glass. It would be beneficial to have a local do a heatload for you. A lot less money than having the wrong size unit and unhappy wife for years to come. With that big sqft split you may consider two systems too. If you don't want to go that route it is usually 400 sqft per ton here in s fla. See if there is a local Johnstone Supply in the area, if you have one that does not lock out non-tradesman you should find what you need. Besides Goodman A/C is made in Tx. Good luck Been more than a few years since I did installs but a cheap ductulator (slide rule for duct sizing)will give you the duct size. Use .08 for the multiplier on the ductulator for quiet ducts. Return air grilles are 144 sqin per ton less they get noisy....See MoreNeed help deciding on HVAC / insulation for our new construction home
Comments (1)Now that you have discovered you have natural gas, are you going to investigate who much it will cost to bring a pipe into your house? I don't see in the load calculation the R values for the walls and attic? Do you know what values were used for spray foam and batt insulation? Do you know how the spray insulation will be installed in the attic? Will it be open or closed cell? The firs quote is for a 4 ton single stage heat pump (XR15) while the second is for a 5 ton variable speed heat pump (XV20i) which is Trane's top of the line product. It is not a fair apples to apples comparison, but the price gap is big. You need to ask about the size for the second quote....See MoreHVAC: House Design - HVAC input please
Comments (6)I suggest separate systems for the first and second floor. That is the best way to have even temperatures on each floor. It costs more up front, but you potentially have lower operating costs. You could zone the loft off the second floor system. However if you are going to be working 10 hours days with multiple pieces of equipment generating heat then spend the money on a mini split....See Morenew construction HVAC
Comments (12)Saltidawg, (Thank you in advance for giving me the opportunity to explain this.) There has to be a motivational reason for a pro to answer questions. It's a form of advertising. I have helped a few local people who have frequented this board. This occupation requires inspection / diagnosis. All you get in a forum board atmosphere are guesses. Sometimes the guesses are right, often cases the guesses are wrong. I could pick nearly any thread on this board as an example. Licensing is required in most jurisdictions. This field is not DIY. No manufacturer will warranty a part or equipment for DIY installations. You don't have to like it, but I serve a purpose here. That purpose pays me back by helping folks that are local to me when they decide to hire me. They know I am local to them: BECAUSE I TELL THEM. How else would you know? I am a Texas Licensed HVAC contractor servicing the Katy, Texas area and some surrounding areas. 832.475.6895 I repair ALL HVAC brands, I am able to design, install, repair and modify HVAC systems. I am EPA universally certified to handle ANY refrigerant. I am NATE certified in installation and repairs. I have an AOS degree in HVAC/R Mechanic graduated with honors (Deans list thru all phases) 1996. You can subscribe to my YouTube channel here....See Moremike_home
