#4 is definitely a Tappan. I service quite a few of those.... 30+ year old 1.5 Ton units still in service.
I appreciate the help guys!
The upgrades should bring this up from poor to average infiltration shouldn't it.
Here are my numbers with average Infiltration.
Sensible Gain 24,727
There will be new insulation with vapor barrier, as well as new windows and doors. With "average" infiltration it's still only 26,820 BTUH heat gain for the "whole house". The house has 1500' down...
Older home but a remodel is in progress. My calculation takes the updates into consideration.
I'm just learning to use the HVAC Calc software and think I may be doing something wrong. I've read the manual and tried to apply it correctly but a 23,452 BTUH Total Heat Gain just does not seem...
High SEER units can be achieved with either refrigerant, just as you pointed out with Trane. It is a natural progression for the manufactures to focus on R410.
I do service on Apt and SFR for a mgmt company. Don't do many installs, one or two a year. I have 8 or 9 years experience but need to get up to speed on R410a.
I understand the logic with rentals but being your personal residence I'd be more inclined to upgrade the whole system. Short of that I'd keep an eye out for an R-22 unit.
Thanks for the encouragement! I thought it sounded undersized off the top of my head but they said it worked okay. Go figure!
Should 5kw be enough heat for a 746 sq ft apt? Is there a general rule of thumb?
It's not a heat pump.
I have a filter grill in the house that I change regularly. I have a package unit that sits outside. Would it create an airflow problem if I stuck a filter in the oustide unit as well?
The 15 Seer is a good unit. It's the only one with the VS blower and Comfort Alert diagnostics system.
It's definitely not very professional but he's been around for a long time. He is actually a licensed contractor who operates in a small town. Now that I think about it I remember an old man who is...
I ran into an independant service tech today that does not even own a vacuum pump. When he installs a new condensing unit he bleeds the air out of the system. I think he said he turns the freon loose...
I had a friend who is a Trane tech tell me he didn't use dryers after a mild burnout but simply used acid-away instead. Is he pulling my leg?
Why is it that Trane does not offer the XL1400 & XL1600 PU's with R410?
