Opinions on a quote.

srkbrcFebruary 28, 2014

I was hoping the experts would weigh in and give me their opinions.
Getting new construction in N. Florida, two story 5000 sq ft, no basement. We have 2x6 construction, icynene insulation, Low-E glass windows. We're on gas. Our builder got a quote from the HVAC guys and the recommendation is as below . Cost $14550.00. Is comfortmaker worth the expense or should I look for another quote.
I was also thinking of creating different zones in HVAC.
Please suggest and give your opinions. Appreciate you time and effort.

Any reason you are heating with electric (heatpump) instead of gas? Why do you need 3 systems for 2 levels?

If you have nat gas available, why not use it?

9 tons of cooling for 5000 sq ft? Really?

Any load calcs offered for your review?

And as said from previous poster, why 3 systems?

Are you inland or coastal?

Comfortmaker not a brand I would want for quality new construction.

IMO

you should also look at higher SEER ratings
as cooling is your main season.

15-17 SEER range have good features
& good return on investment.

best of luck.

Thanks for the opinions sktn77a , tigerdunes and energy-rater_la.

i am not sure why the builder asked the HVAC guys to go with electric system when I told my builder that we can use natural gas for HVAC.
Not sure why three systems and I did ask him for the manual j load calculation, which he said he will provide me.
We are inland, Tallahassee to be specific.
Any more suggestions or questions I should be asking my builder or HVAC guys. Please help.
