Heat Pumps for the Mountain West

Mountain West climates are cold and dry — Denver gets 150+ days below freezing — but electricity is reasonable at $0.15/kWh. Cold-weather COP matters here. This tool calculates total 10-year cost including supplemental heating for hours when the unit can't keep up. Cold-climate models are pre-filtered. Set your location on the map for results with your local weather data.

537 heat pumps match this filter. Showing top 50 by SEER2.

Frequently Asked Questions

How does altitude affect heat pump performance?

At Denver's 5,280 feet, air is about 17% less dense than at sea level. Less dense air means less heat transfer per cycle, typically reducing capacity by 5-15%. Variable-speed compressors compensate better because they can ramp up to make up the difference. The capacity numbers in the tool are at sea-level conditions, so plan for about 10% less at Denver altitude. Not a dealbreaker, just something to account for when sizing.

Does dry climate help heat pumps?

Yes, and it's a real advantage that rarely gets mentioned. In humid climates, heat pumps spend a lot of time in defrost mode — reversing the cycle to melt frost off the outdoor coil, which temporarily stops heating. Denver's dry air means way less frost, so the unit runs in heating mode more consistently. You also don't need dehumidification features for cooling, which simplifies model selection. Real-world performance in the Mountain West tends to beat the published ratings.

What about the big temperature swings?

This is exactly where variable-speed models shine. They modulate output smoothly to match whatever the temperature is doing, instead of just cycling on and off. On a mild 50°F spring day, a variable-speed unit runs at maybe 30-40% capacity, quietly and efficiently. When a cold snap drops things to -5°F that night, it ramps to full power. Single-stage units can only do on or off, which wastes energy during the shoulder seasons that make up a lot of the Mountain West year.

Can a heat pump compete with cheap Colorado gas?

Colorado gas prices are among the cheapest in the country, which makes this a tighter call than in the Northeast. But a heat pump doesn't have to beat gas at every temperature — it just needs to win for enough hours. Above about 30°F, a decent heat pump crushes gas on efficiency, and Denver has a lot of hours above 30°F. Dual-fuel (heat pump primary, gas backup for the coldest nights) is popular and practical for the Front Range. Enter your rates in the tool to see the full-year comparison.

This is a prototype I'm working on, and would love feedback - send any thoughts/comments/suggestions for improvement to tophatmonkey@gmail.com

This page is made to help you figure out heat pumps. Heat pumps used to have universally terrible performance when it got below 40 degrees, but in recent years, that's changed - some now work well down to -22! But that's not true for all heat pumps, which is why I made this tool to use the actual performance metrics to estimate how each would behave with your house, in your specific location and your weather.

How?

First, use the map to choose where your house is.
Using that, we get the hourly weather for your location for the full year.
Then, use the text boxes to describe your house - where is it, how big it is, how well insulated, and how much your electricity costs.
Using that, we make a model of your house and estimate heat loss for every hour.
Using those together, along with capacity/efficiency data at different temps for lots of heat pumps, we estimate how much electricity each one would use, and figure out which ones won't be able to keep up - look for "Hours Over Capacity" to see which heat pumps aren't quite keeping up. A little of that is OK, a lot, not so much.
The page combines the purchase price (amortized) with the annual electricity cost to show a blended cost per year. A more efficient heat pump might cost more upfront, but if you need a lot of heating or cooling, it might end up being cheaper overall. We sort by that annual cost.

This page may look kind of crappy, but don't judge this book by its cover! It's more sophisticated than most pages that look a lot nicer.

Heat pumps are pretty awesome. They're basically air conditioners that can run in either direction, and because they move heat between in and outside instead of just creating it, they can be more than 100% efficient! In many cases, they're in the range of 400% efficient, or even more. You can get more heat in your house using natural gas to generate electricity to run a heat pump than if you burn the gas directly in your house. Crazy!

This tool is for people who are interested in buying a heat pump without going through a contractor, or for any contractors who might find comparisons useful. In many cases, especially with minisplits, it's not too hard to do it yourself, and much cheaper than hiring a professional. But they can be a bit tricky to compare when it comes to efficiency versus cost tradeoffs, which is why I built this tool to help you play around the numbers and figure out what might be right for you.

If you decide to DIY this, though, I'd advise a few things. First, watch a bunch of YouTube DIY videos, but be aware that it's not quite as simple to do a good job of it as they show. If you get one of the MrCool DIY series pumps, you can just use their pre-evacuated linesets, and I've heard that's pretty simple. But if you go with one of the others with normal linesets, you need a vacuum pump, torque wrench, and the other tools they recommend, but you also need a digital micron gauge, a flaring tool, and you probably want a coring tool with shutoff valve, and you might want to do a pressure test with nitrogen, which means you probably need a pressure regulator. You probably also want a higher quality vacuum pump than most YouTubers show. Many YouTubers use an analog manifold, but for pulling a deep vacuum and making sure it holds, that's like trying to measure inches with your car's odometer - the level to which you need to measure is invisible on that scale. Instead, you want a digital micron gauge. This isn't to scare you off, I did my own this way and it wasn't hard once I figured out what I needed, this is just to make it so you don't get halfway into your project before you realize the real cost of doing this right.
