I I'm installing a Honeywell rthl2510 thermostat on my heat

I I'm installing a Honeywell rthl2510 thermostat on my heat pump system. I have the wiring completed and started the system. The cool on indicator is on though the system does not operate. I noticed something in the installation instructions about a Y1, W1 & W2 needing technician service. My old system has a Y, a W1 jumpered to the Y and a W2. There was a jumper from the W2 to an E terminal on old thermostat. All that to say does this system qualify as a Y1, W1 & W2 system that needs special wiring? Or have I just not wired something correctly? For reference, I have the W2 wired to the W/Aux terminal

My water heater (30-gallon, gas) has reached the end of its

Hello,My water heater (30-gallon, gas) has reached the end of its useful life. I'm considering my options, but I have a fairly specific situation.My partner and I live in a loft-style condo in San Francisco, with the bedroom on the second floor, open air style (no windows to the outside). My water heater is in a closet in the bedroom. Although the exhaust is pumped outside of my building, the ambient heat tends to stay in my bedroom and cause it to get hot, which is annoying in the summertime. I would like to buy a water heater that solves this problem. Will an electric water heater or a tankless water heater solve this problem? Are there other options that will help solve this?Thank you!

My 1997 Trane XE 1200 TTP060100A4 (with HCFC 22) failed and

my 1997 Trane XE 1200 TTP060100A4 (with HCFC 22) failed and was replaced with a Johnston Supply RAC13J604S21 (rated at 5 tons) and a Goodman CSCF4860N6 coil (4 to 5 ton horizontal slab coil). they don't seem to cool as well as the old Trane before it failed. Why? Is it the new coolant that is required now not as good?

Live in midwest. 2100sq ft home. Ac/heat pump unit. 36000

live in midwest. 2100sq ft home. Ac/heat pump unit. 36000 btu rating on label. I know the sq ft is not the only guide for sizing a unit. Home is standard wood construction built around 2006. My question is does it appear to be under sized just by the sq ft? 12in of insulation in attic etc. We already did black out draps etc and its run all day last few. It has been 95 plus so know its going to be struggle regardless but feel should be able to keep temp under 78 if running constantly.

I have a 23 year old Ruud Scroll 3 ton unit in hot and humid

I have a 23 year old Ruud Scroll 3 ton unit in hot and humid south Texas, the compressor shorted to ground and Choice Warranty is telling me this is a lack of maintenance. The unit was working fine two weeks ago. We had our first heat wave (into the upper 90's).Is a 23 year old unit with the outside unit and inside air handler in perfect condition, a maintenance issue?
