call dealers around you, that have the brand you are interested in, and ask. Does your house already have the ducting, or do you need all that too. Once you have decided on a dealer and a brand, then they will come and give you a complete estimate.

Pricing is very regional. What may be a good deal at one location may not at another. Also, now isn't the best time to buy anything. But if you must, call around at least 5 dealers and ask for a quote on an apples to apples basis (may be very difficult).

When it comes to HVAC, now is probably the worst time "ever" in history -- to replace an HVAC system.

Why? The industry is right at the cusp of changes that pretty much effect upwards of currently 70% of what is made now.

By the end of the year everything made now the left overs, the stuff that doesn't comply will be illegal to sell in Texas --Florida probably won't be much different. Part of this is due to DOE changes to what efficiency standards are going to. SEER to SEER2, they changing the calculation to these efficiency requirements.

To make matters worse... R410a -- a refrigerant that has been used for just over 20 years now, is on the chopping block. Prices are already up over 300% since middle of last year or so.

Equipment, what can be found the prices are up across the board. If you can find it and need it you better buy it before someone else does or do without. The world has changed from what it used to be thanks in part to a perfect storm.

Now if your view is that R410a systems are likely to be better than anything these manufacturers can produce looking forward for the next few years due to what is likely to be refrigerant wars breaking out among mfgs and you want to try to skip all that nonsense of what is coming... then find a system that does what you like now... because what is coming *could be* one hell of a mess.

If your system develops a leak, pay someone with skill to fix the leak. Interesting times we live in right now. History... like it? hate it? Make your voice known and I may include your opinion in an upcoming video on my YOUTUBE CHANNEL

I service the Katy, Texas area.

You should budget at least $8K-$10K for a replacement. The price will vary significantly based on the equipment you choose. It seems the installation costs in Florida tend to be less compared to other parts of the country. But that may have changed given the current supply and demand problems. Multi-stage variable speed equipment is going to be in the $10K - 12K range.

Do you know how much it costs to heat your 2200 sq. foot house? It might make sense to install a heat pump instead of an electric furnace. Heating with a heat pump will about 1/3 the cost of an electric furnace. The initial installation costs would be higher, but you would have reduced heating costs each year.
