Dear HVAC Talk Members:
I have been living with the problem of having the front 2 rooms of my 2nd floor of my house (the furnace is in the back of the house, in the basement) being hot in the summer and cold in the winter. I live in TOronto, Canada, and temperatures can swing from icy cold in the winter, to hot hazy and humid in the summer.
We have an 18 year old furnace and AC unit (120,000 BTU and 3.5 tons) made by Keeprite (owned now by Carrier). These units are in very good shape (well maintained yearly). Of course, their energy efficiency is lower than today's newer units...but what we care about is COMFORT IN THESE 2 ROOMS!!!
THE PROBLEM IN THESE 2 ROOMS is AIR FLOW. WE don't get enough air into the room through the ducts, and so this is causing us issues with getting heat/cold into the room. The ducts are at the "end of the run" and are far far away from the furnace. We want to resolve this, as we are having a baby, and want to make sure that the baby is comfortable.
A contractor is suggesting, in order to solve our problem, that we do the following:
1. Change our furnace to a Carrier Infinity 58MVB120 model (2 stage heating unit) - likely a Carrier 96 from what I can read on the internet.
2. Change our AC unit to a Carrier Weathermaker 2 Speed 38TDB 5 Ton model.
3. Redo the basement ductwork to create a single special "run" of ducting just for second floor vents.
3. Install a zoning system, and install controls/dampers to allow the furnace/AC to send air only to the 2nd floor.
4. Install 2 Infinity thermostats in the house (one on the main floor, one on the second floor).
IN YOUR OPINION, WILL THIS SOLVE OUR AIR FLOW issues?
Thanks for your insight/guidance/suggestions.
