I have a new York 4 ton 15 SEER heat pump with 5 ton York air handler with expansion valve; it also has a coil behind the air handler going into supply line from an outside wood boiler.
I think the fan motor is 1 hp variable speed motor, 1050 rpm. I don't think it blows enough air out the vents.
With the boiler water temp outside at 160 degrees, it took from 9:30 to 12:00 (2.5 hours) to bring the inside temp from 57 to 62 degrees.
- Outside temp was 46 degrees.
- It is a 2400 sq.ft. heated space.
- Walls are foamed 1/2", with 6" insulation.
- Ceiling has 12" insulation.
Can I get a higher rpm motor to turn the fan faster to ultimately solve this problem, or is the boiler coil reducing the air flow too much?
If not, what do you think the problem is? I asked the HVAC contractor who installed it but they are not helping.
If you need more information please ask.
