Consider reinsulating your attic space with spray foam. That is what we are doing.

As for your HVAC, regular cleaning of the coils and replacement of the filters. Believe it or not, when our system runs, I change the filters every 30 days. A friend of mine had his own HVAC business, and installed the new system in the home we sold, was big on that. I agreed. Cheap insurance.

Thanks. A friend had suggested spray foam option; he did in his own house. Worth looking into for me.
My house was built late 2006--almost 20 years old. The HVAC system keeps going but a local HVAC company last year said some plates for the Emergency heating are almost gone and if the HVAC system fails then no heating. But the quote they gave for a replacement was over $8000 for the HVAC unit (attic and outside ones) with the duct system not needing any work. I think we are going to run it to the ground before replacing. It maybe costing us a little extra per month with an inefficient system but forking out so many thousands is not I am ready for. I just hope ours doesn't break down during a severe cold wave.
I replace HVAC filters every 3 months--they are 3 months filters.
