We experienced a lightning strike to the home and will be upgrading the AC system that went bad.
We current have a 2100 Sq Ft home, 10ft ceilings. Louisiana (near Baton Rouge) Age 11 years old, good insulation, High pitched roof system. 1 level home.
Ruud 4 ton 12 seer
Furnace Ruud 80k BTU Horizontal feed
Rheem 12 seer rated coils
The current system we have has never been able to keep the house adequately cooled. If we set the temperature below 76 degrees the line will eventually freeze up. It can run for hours sometimes and lose ground.
Let me also say that I have a home business and have three computers running 24 hours a day that also throw off a ton of heat as well.
No Manual J was done.
Installer recommended a Goodman setup with an Amana Furnace
Any advice would be great for this.
Thank you very much,
