In Los Angeles, California, a 1,000 square foot home requires data points such as home square footage and climate zone. A gas furnace calculator can help determine the appropriate size for a home in each zone, with zones 1 and 2 having varying BTU requirements. For a 2,000 square foot home, Zone 1 needs 70,000 BTUs, while Zone 2 needs 80,000 BTUs.
A 100- to 200 square-foot room, such as a small home office, should have an average recommendation of 4,000 to 8,000 BTUs. For a space of 800 to 900 square feet, such as a small home or two-bedroom, 4,000 to 8,000 BTUs is recommended. Your local Carrier dealer can perform a load calculation to determine the most appropriate size for your home.
Fire furnaces are differentiated by their BTU capabilities, which represent the amount of energy required to heat one pound of water by one degree Fahrenheit. A replacement forced air furnace would be sized at 80,000 BTU furnace at 95 efficiency. Quotes on boilers range from 120,000 BTU’s to 175,000 BTUs.
The general rule of thumb for furnace size calculation is that it takes 30 BTUs for every square foot of house. For example, a 1,000 square foot home with 68+ BTUs inside and 32 outside would require a 36k BTU heat pump to stay on twice as long but still get the job done.
Gas furnaces are sold by input capacity and output capacity determined by AFUE ratings. The general rule of thumb is that you need between 30 and 60 BTUs per square foot, depending on your climate. Climate zones can help you determine the appropriate size for your home.

How many BTUs should my gas furnace be?
In order to calculate the appropriate furnace size, it is necessary to determine the number of BTUs required for each square foot of the house. Therefore, a house with a total area of 1, 000 square feet will require a furnace with a minimum output of 30, 000 BTUs.
How big of a house will a 80,000 BTU furnace heat?
An 80, 000 BTU furnace is capable of providing sufficient heat to maintain a temperature of 20 degrees Celsius in a 2, 000-square-foot residence. In order to calculate the requisite square footage for heating, it is first necessary to measure the length and width of each room. These measurements should then be multiplied in order to ascertain the area of each space. Once this has been done for all rooms, the total square footage needed for heating can be determined by aggregating the individual amounts.
How many square feet will a 60000 BTU gas furnace heat?
The dimensions of the furnace and air conditioning apparatus for a semi-detached two-story residence are contingent upon the square footage and the desired output (BTU/hr) for the domicile.
How many square feet will a 70 000 BTU furnace heat?
The dimensions of the furnace and air conditioning apparatus in a bungalow may fluctuate contingent on the geographical location. The typical output ranges from 1500 to 1800 BTU/hr, with the square footage not encompassing the basement area.
How many BTUs does a 3000 sq ft furnace use?
The HRAI suggests that in regions with colder climates, high-efficiency furnaces should adhere to a 30 to 45 BTUs per square foot standard. This would typically necessitate a furnace with a capacity of between 90, 000 and 135, 000 BTUs for a 3, 000 square foot residence.
What is the difference between 40000 and 60000 BTU furnace?
A British Thermal Unit (BTU) is a unit of measurement used to rate furnaces. A 60, 000 BTU furnace produces more heat than a 40, 000 BTU furnace. Residential furnaces typically range between 40, 000 and 120, 000 BTUs. They also have an AFUE rating, which should be prominently labeled by the Department of Energy. The BTU is the amount of heat required to raise one pound of water by one degree.
📹 Should I get a Gas Furnace or Heat Pump System? (…in about a minute)
If you’re asking yourself right now, Should I get a Gas Furnace or Heat Pump System, it will depend on a couple things. Watch this …
I switched from nat gas air force furnace to a heat pump HVAC is saved a TON of money, but I do have solar panels so virtually all of my electricity is free. I find the heat pump blows hot enough air, even in the coldest nights, and super cold air on the hottest summer days. No doubt, the way to go is a heat pump system with solar panels.
Natural gas, these days, is often a good choice for heating, but you have to factor in the political risk that low NG prices may disappear. LP and electricity pricing is often a wash, although LP follows fuel gasoline pricing so electricity might be better currently. This is for conventional packages as the mini splits improve heat pump performance at low temps. The real loss of efficiency in operation and ignoring poor low temp design of older conventional systems, come from the need to defrost the outdoor coil using indoor heat or part of the heat from the electric resistance coils. So cold weather efficiency will be better where low winter humidity is the norm.
Good article / Good Topic – Right now – 8/2021. 1) Most inexpensive & Most efficient is Nat. Gas / Lp gas Heat & Mini – Split cooling. 2) 2nd best is – a Package unit. Gas/ electric. no strip heat. 3) 3rd best is – standard gas/electric split systems. No strip heat. Gas/ Electric with standard Split system cooling. In a Perfect world – Where I Believe the Government is trying to get to is All Electric cooling & heating using 100% renewable resources for Electricity creation & storage. The Problem is – Electricity COST TO THE Consumer right now is off the charts & rediculous. Electric cost MUST BE Economical to the Consumer or Your Going to have a lot of very pissed off people as the Government transitions to All Electric without keeping Electrical cost reasonable.
I get a little concerned when people refer to heat pumps as electric heat. Yes they run on electricity, but they are ~2-4 time more efficient than resistive heat (heat strips/coils). Heat pumps take the heat from the air outside and move it inside, and yes, there is heat in the air in wintertime; all the way down to absolute zero. I live in Minnesota and I use my heat pump to heat my house in the winter. At a certain temperature outside and depending on propane costs, the propane furnace takes over and the heat pump turns off. I use a balance point work sheet to figure out at what temperature I switch to propane. In my area Natural gas is the cheapest to heat with, than air to air heat pump (depending on outside temps) and them Propane. Also, fuel oil and wood are in the mix somewhere, but electric resistive heat even at 100% efficiency is the most expensive. But if Geo thermal was cheaper to install, I would have gone that way for sure. They just aren’t there yet.
the issue with having your heating/cooling/cooking all on electricity is : what happens when there is a blackout? i understand the allure of going all in on electric but really natural gas is far less polluting than petrol/diesel and if i had to pick something other than electric i would pick natural gas (or alcohol based fuels in future)
This article makes it seem like Heat Pumps are trash, if you’ve found this article you’re probably doing some research so understand that Heat Pumps are generally more efficient than AC/Gas. Understand your average costs of operations, will you continue to use Natural Gas (Hybrid systems are available), have your heating/cooling demands measured and explained to you for your specific region, if you live in a colder climate zone (yes there’s maps available for this that your contractor can explain) then a heat pump might not be ideal if your system will run at full load and still need auxiliary heat then you’re losing savings potential. Explore modulating systems that can deliver part load capacity that can help keep you efficient.for the season compared to it’s highest demands.
Here in Northern New England (150 miles from the Canadian border), heat pumps will be a tough sell for a long time to come. Many people around here are on Propane/NG with many having a permanently installed Generac generator as backup..which seems to work best. While the -20 Temp and -30 Wild chill we had just last week are not normal temps, we do get extreme weather and at least for now, it seems heat pumps are a much better solution for people living to the south…of a Boston latitude.
Whenever I get or purchase my own house 🏠 and I have a Central AC and heat. I will most definitely clean my unit out in the spring months and ready to be used for the summer months. And I will change my filter every month to be most efficient and last long. I’ll probably will most likely too rent out a solar panel too reduce my energy bills especially my electric bill.
I have to replace my A coil, line set and out door 5 ton condenser. With LPG cost going up and down and issues with getting it. I am considering replacing the 5 ton with a 5 ton 15-Seer heat pump and a new A coil and new TXV. I’ll also replace line set as I am moving the outside condenser over a bit. Question I like the Gas furnace and the heat, so I want gas heat most all the time. So which Thermostat and or items would be required for me to have total control of when or if the heat pump or furnace is give the command to operate. And if there are wrong or right heat pumps to get. My system is Goodman and it’s been great. Looking at the GSX160601 and the CAPF4860C6 A coil. My furnace is a Goodman GMNT-120-5 92% LPG furnace. Suggestions from knowledgeable people have kept me alive so far so I am open, thanks, Ron
My sister who is close to 80 lives in Nevada County. House was built in 1999. She has a Heat pump. During this last now she lost all electrical all propane. She is convinced that the heat pump is connected to a propane line underneath ground and used for heating. My question to you, are heat pumps, and I understand the theory, use propane.? I can’t find the answer anywhere? Thank you in advance
A question for FFH…an existing 5T package unit mounted up on the roof of a home needs replaced, its 21 years old. Never seemed to function too well, it could generate cold air but the interior always seemed to be warmer than it should. So, question is, would it be advisable to go with a split system or another packaged unit on the roof? I’m thinking a packaged unit doesn’t work as well as a split system, is this fair to accurate thinking? Is equipment cost more or less between the two for similar units and would labor be more or equal between them? I’d imagine the roof would have to be closed up so I understand that would be an added cost if changing it to split system. I just don’t understand why a packaged unit would be put on the roof of a residential home.
This guy has no idea what he’s talking about. Electric air source heat pumps are, in some cases, almost 350% more efficient than combustible fuel sources. The COP of these units are amazing between temperatures of 30 to 5 degree’s and even still put about >75% or more of name plate below zero. This is garbage information.
