I'm a homeowner with a few questions about my HVAC system. Sorry if I don't have the terms down properly
The system is a 3-year old Bryant HP/Gas system, handling about 3000 square feet in the Kansas City Area. The stat is a 5+2 day programmable, dual-mode, automatic unit.
Question 1: is it normal for the blower to reduce speed for A/C actuation? Heat and "Fan Only" run at full speed, but A/C is reduced.
Why I ask: I had techs out 3 times for failure to properly install and charge the system. As you know, the condenser became a block of ice until they detected a faulty coupling install.
The Problem: In the summer months, the system has a tough time cooling the house (consistently runs from afternoon to bedtime). I'm not sure of the tonnage, but I can pull the panel on the compressor to find out. If the blower speed should be at full power for cooling, I suppose I would need to have a tech adjust that.
Question 2: Of course this is a very inefficient "builder's grade" system, and the utility bills are rather high. Would it make sense to have someone install an intake runner in the basement to draw cool air for summer (with a damper of some sort for Winter)? I have the vents and output sections adjusted for the rarely used rooms and hot spots. The flat, backside of the house faces West, which is also a challenge.
My expertise is in vehicle fuel economy -- so I'm a bit lost with HVAC. I'm a moderator over at the EcoModder.com Forums -- perhaps I can help return the favor for anyone looking for advice on saving fuel.
Thanks in advance...
