Don't forget to calculate for efficiency. 45,000 BTUs X .8 is 36,000 output BTUs assuming its 80% efficient. Keep in mind it will only average your heat loss. No need to run it for a week just go out on a cold night and watch in run for 3 hours and it will give you a good BTU loss of the...

The radiant floor is not cheap and is really not needed since i will have a ductless mini split heat pump, but I also own the largest WaterFurnace Geothermal HVAC dealership in the NW so geo radiant floors is my business :-) and I am running radiant floor in the master and possibly a few other...

We are building a new home and I have attached the blueprints for the garage level. Home is three stories on a hill so garage is mostly underground. Garage will be spray foam insulated to make sure no exhaust fumes go into the home above. Plan on having daily drivers on the left side of the...

I am a car guy and have seen this forum referenced from other car forums so I thought I might as well join. I am custom building my house and hopefully breaking ground in May, and getting ideas for the garage. Will be three car wide with tandem bay, 10.5' tall ceilings so I can hopefully ad a 4...

Just wanting to correct some information here for others, COP on heat pumps range from around 3-5.3(worlds most efficient heat pump depending on how you figure COP is the Waterfurnace 7 series at 5.3 COP at part load) I think the 20 number you are referring to is SEER which is a common cooling...

How old is this unit? R22 units have not been legally manufactured for many years, are you sure it's not R410a? Did you buy the unit yourself and hire somebody to install? If so you may be up a creek because those online units are not warranties by local distributors in my area, they keep...

Up to 150CFM, bad ductwork with bad diffusers will put you typically closer to 100 CFM. An average diffuser cuts back surface area by 30% and the best designs still take up 20% OP, I would highly recommend against buying on One, you do not usually get a local warranty and while goodman is...

Bingo, with only electric or LP you need to at least consider this option, LP is an arm and a leg to operate and geo will save about 70% over LP but will cost more up front. Geo also qualifies for a 30% of the cost tax credit! I am doing a geo radiant floor in my garage with a ductless mini...

Ok as a HVAC contractor that is a Mitsubishi Top Contractor and a Daikin Platinum 3d dealer let me dispel some myths. Two wall heads will probably be your best bet, most systems have a "throw" rating of around 28' so beyond 28' the airflow diminishes. A mini split IS NOT meant to run only 1-2%...

You can actually go to 8 indoor wall heads or ducted slim air handlers or ceiling cassettes off one outdoor compressor bearing unit. Mitsubishi makes a 2,3,4,5,8 port outdoor heat pump and Daikin makes a 2,3,4,8 port system as well. In a commercial setting the possibilities are endless, my...

Did anybody perform a load calculation and measure your windows and walls and get insulation values. Larger is not better when it comes to HVAC and many homes actually benefit from a smaller system. My experience, I own a 34 year old nationally recognized Trane dealership in Portland OR. The...
