Hi, I'm glad I found this place as I know nothing about HVACs. I hope it's all right to ask if a quote I was given is reasonable or too high. My HVAC was installed when the house was built in 1992 so it's almost 20 years old. I was thinking of replacing both the heat furnace and AC unit together. We have local contracters who claim to have a very low price if the two are purchased together. I don't know if it's normal for the quoted price to include everything, i.e., equipment, labor, taxes, etc. but this quote does include everything. The humidifier info they sent me is for the Healthy Climate HCWB3-12 or HCWB3-17. The quoted price is way over on these. My house is just over 1,600 sq. ft. and 12 model prices I saw ranged from around $127-$185 so $400 is steep. I really appeciate any input. Thanks very much for your time.
