It sounds like you have a great filtration system.

Being familiar with the basics for a furnace operation and typical failures, I do not understand how a top notch fibrillation system could save the burner assembly from failure. The filtration system keeps the heat exchanger much cleaner on the outside and may improve heat transfer, but does little to protect the parts of the furnace that typically fail.

And I do not understand how a thermostat will save on heating fuel. To keep a home at 70 degrees (or whatever your desired temp) it takes a certain amount of fuel, which means the furnace has to do the job and burn the fuel to do it. The only way it could save fuel is automatically lowering the temp on certain occasions, such as night time. Many have less expensive thermostats that already do this, we do it manually as we go to bed and then get up in the morning.

depending on the age of your current AC, consider replacing it just before the new mandates go into effect with a current one. I get about 20 years out of my AC units in Texas, but you need to service the unit regularly. 15 to 20 years will get you down the road a long way.

I have similar concerns about water heaters and AC's. So I will be buying a new H2O heater to storage for the future.

Nest is Google, and I hate Google. And I’ve had a Nest thermostat, and like Ecobee smart thermostats and their UX better. I have three in service currently, had two others in a house I sold last Spring.

In short, buy Ecobee, not Nest.

I recently replaced my HVAC with a higher SEER rating (same manufacturer, nearly same form factor). It is much more efficient and the transition to the 5 inch thick (20X20X5) air filter also works better than the 1 inch thick ones I had in the old system. I’ve got 15 months of usage now and the resulting bills for heat AND air are noticeably lower than before.

You might also want to consider having your HVAC service unusual a Micro-Air easystart device to reduce the current draw from the AC compressor both startup & running. There are several models depending on the AC tonnage of your system. Link us https://www.micro-air.com/products_easystart_368_softstarter_microair.cfm

I just looked for “Powered Furnace Filter” on YouTube and found nothing that fit that descripton — could you clarify?
