heat pump

Hi all, Have enjoyed learning from these forums for many years, and finally ready to ask a question... Our new home on Cape Cod Massachusetts (Climate Zone 5) is very well insulated but has architectural feaures that are challenging - some vaulted ceilings and lots of large windows. There is...

I have recently had a Bosch IDS Premium Connected Heat Pump Model #BOVD-36HDN1-M20G and Air Handler Model #BVA-36WN1-M20 heat pump system installed with a hydrocoil connected to my Navien NFC-250/175H firetube combi boiler. The system is split into 2 zones, 1 for the 1st floor and 1 for the 2nd...

EDIT: I just noticed there's a GM9C800804BN -- which is a 1600 CFM version of the same 80 Kbtu, 80% afue, 17.5" wide cabinet!! So I guess my problem is solved! (I changed 1200->1600 below) ---original post--- Looking for advice on selection of a width for Furnace+Coil pair -- 17.5" or 24.5" --...

Entering our first winter in the northeast with a multizone dual fuel heating system. System is a Trane: XC95M Furnace, XV20i Heat Pump, and XL1050 Control. The heat pump has been fantastic, but now that its colder I'm curious about efficiency, cutover, and NOISE. Right now it is 20 degrees out...

We are in the process of changing out the rooftop Condenser and ducted Air Handler for my Heat Pump system that was originally installed in 1997. The contractor(thru a warranty company) is changing the 3 ton Carrier unit to a Lennox unit. I believe the air handler was by First Company and they...

A bit of a theoretical question as our SEER 16 a/c system is ok. Big old 3 story + basement 3800 sf house. Western PA. Heat is new Weil-McLain EVG-220 hot water system with big old rads all over the house. 2 central A/C systems - first floor system & 2nd/3rd floor system When the 2nd floor...

I'd like to change the thermostat that controls an Amana heat pump because it's incredibly unintuitive. I often see the following warning on the back of many thermostat packages: For use on heat pumps without aux heat. Sometimes instead of the term 'aux heat' I see 'emergency heat' or 'backup...

I have a Bryant 607ENXA42000-TP heat pump, installed in 2015, that has recently developed an odd problem. Five service calls by the dealer/installer and multiple parts replaced have not solved. It's been maintained quarterly, and cools well. What happens is that mostly during the night, the air...

Good morning, this is my first post so I’ll start with a introduction of myself. I’m an extreme DIY’er. Basically, by that I mean I DIYer who will get into big projects without fear. But I am not a professional in any specific trade. When Hurricane Florence destroyed my house, I decided to take...

I am looking for a suggestion which helps me to detect the temperature conditions of the area where Heat Pumps are working. With some google search, I found many interesting products which use to work with but I am looking for the Battery powered sensors which can send the data at a very long...

I have a dual fual heat pump and gas furnace. The heat pump is a 2 stage unit and the furnace is a 2 stage unit as well. Am I correct in thinking I need a 4 heat and 2 cool stage thermostat. Such as a Honeywell prestige iaq

Has anyone heard about Midea Mini Split Air Conditioner before?

House built in 1990, 1100 sq ft, 500 finished basement located in seacoast NH (heating 99% is 9). House is well insulated, not drafty at all. Basement was an upgrade done 10 years ago by previous owners and it is cold, even though it has a baseboard (too small for the space). Current boiler is...

Hello all, I am not very experienced, so please forgive me if this sounds naive. It will not bother me if you tell me I'm completely off on my calculations or being taken for a ride on the estimates. Regardless, I certainly can't afford to do all these. This is for the northeast. I used an...

Hi all, thanks in advance for the input. I live in Poughkeepsie, NY and am looking for some input. I have a 1960 Split Level 1800 square ft house which is getting a complete HVAC system replacement. We have spray foamed the roof deck and the envelope around the garage (6-8" open cell foam)...
