I have 6 HVAC companies coming out to my house to give me a quote for a complete system, including duct work. They have all said it would take 30-45 minutes, I thought this would be closer to 2 hours to take the all necessary measurements for a Manual J calculation and time for my questions. Even the most respected name in OKC was no different.
How long should I expect an in-home consultation to take? Should they do a load calculation per room or for the house as a whole? I do have an atrium, so more glass windows than most houses.
Thanks for any help with unknown world I'm entering!!!
