    We're making plans to increase the ground level of our old house we bought almost 3 ft to be proactive against occasional flooding from a creek on the property. The Goodman HVAC system is ground level and needs adjusting. This closed system with a large duct apparently through the foundation is...

    I live in the relatively moderate Pacific Northwest. I'm going to replace my old electric 5500W 50gal water heater and I'm trying to decide to stay conventional or go with a hybrid heat pump type. My concern is the water heater heat pump's heat extraction from the living space during the winter...

    Hi all, have been considering a mini-split system for a while now, my current set up is multiple a/c window units in the summer and a gas-fired wall heater in the winter. This is for a 1200sq ft 3bd home in Southern CA so the current set up does ok, it would just be nice to have something a...

    Hi, I'm getting ready to install a small heat pump system in a 400 square foot Adirondack cabin later this year - and I want to try a air source plus geothermal experiment. perhaps others might be interested I already have 400 feet of 1 inch tubing buried at 4 foot deep under and adjacent to...

    Hey everyone! I've been doing a lot of research on heat pumps (live in Maine and oil prices are killing me) lately and something just hit me - I have forced hot water basedboards fueled by oil and not sure what happens if I'm running heat pumps - do they run in tandem? I have a 1200 sqf home...

    Received a quote listing the following: "2.5 Ton Heat Pump Unit 15 SEER Grand Aire (Carrier Corp) AHRI CERTIFICATE 204862042" I go to Grand Aire website and cannot find a 15 SEER Heat Pump only 14 and it's a package unit, unfamiliar with this, it looks like something commercial/industrial...

    I am close to springing for a second story ducted mini split without supplemental heat in climate zone 5. The outdoor unit is a Carrier 38MARB 1.5 ton HP. I have spent a lot time researching this project but I had ignored the defrost function. Now I feel like Jessica Simpson because when it...

    Have a Goodman Heat pump that quit today. Called a repair and the technician diagnosed the unit with zero refrigerant and a leak. System was manufactured in 2005 with the R22 refrigerant, 148oz capacity of R22. Technician said it would take 9lbs to fill system. He quoted R22 at $400 per pound...

    I just moved into a house with a Coleman electric heat pump and an electronic air cleaner. It's fairly old, almost 20 years, but the house has sat mostly unoccupied for almost 15 years. Had an HVAC contractor check it out and he said it is in good operating condition... I have questions and...

    I am swapping out a Honeywell TH621OU2001 thermostat for a GoControl GC-TBZ48 smart thermostat at a new home we just purchased to make an airbnb. We use the same GoControl thermostats at all of our Airbnb's and I have installed dozens of them. We chose GoControl because we have a couple houses...

    Bought a new place last year with a gas Furnace. I was kinda stoked because I had always heard about how energy efficient they are. Boy was I let down. In 14 days my Gas went from 70% to 0%, in a 500 Gallon Tank. I was left waiting for the gas company for 7 days and I said to myself that Gas...

    Hi, my heat pump system started acting up this morning. The air handler has some error codes on it that I can't find information on. I have a tech coming out tomorrow, but I'm curious as to what they are.

    Hello, I have a Goodman GSZ160301 16 SEER HP, 2.5 TON heat pump w/ the AVPTC37C14 Air Handler. The fan speed is 1/2 or less than my old unit - based on same exact ductwork + filter. The Comfort Cloud app is showing 460 CFM during heat pump heating. I wanted to up the speed because the suction...

    I am observing behavior I cannot explain. My Bryant single-stage 2-Ton heat pump (3 year old 214DNA024-A, operated with a Honeywell T6) works fine for heat/cool at any temperatures above about 23F. When outdoor temps go lower, it will kick on for 5-60 seconds at a time, then pause for about 3...

    Hi, I have a Trane XL15i Heat Pump that seems to be generating less heat this winter (although it still does generate some heat although it seems to feel cooler than last winter). It is currently 40 F outside (humidity 85%), and it seems that every time it runs it ends up going into defrost mode...

    I went to connect my gauges to a charge port on a Carrier 38MGQC18, and the port on this Carrier outdoor unit is slightly larger diameter than the typical Schrader connection ports I am used to. Is there an adapter I can get to connect to the Carrier charge port? photo at...

    This is just hooking up the gauges without the compressor running. Shouldn't they be equalized? Shouldn't both of them read identical? As you can see one of them is pegged out the high pressure is pegged. I'm pretty sure my unit is running just on electric heat and not running on the compressor...

    I know there are DIY ductless heat pumps available, but I'm looking to retrofit a ducted system into the space designed for a downflow furnace in a manufactured home. I haven't seen any advertised DIY systems that are designed to mount the air handler in a downflow orientation. Even the MRCOOL...

    I'm talking to an electrician about wiring my pool heat pump, and I'd like a second opinion on his plan. I'm in central Virginia. The pool is already installed with a 60A GFCI pool panel, so this is just the addition of a separately fed heat pump. The heat pump will be wired from the main panel...

    Hi All! I had a tech come out today due to a fault being thrown by my Goodman 2-stage heat pump (split system). Code was for outdoor coil temp sensor. Tech indicated that condensor fan was not running at full capability when system was in high mode causing the condenser coil to over heat...
