The 10 Ways that Mini-Splits Pay for Themselves

After being the standard heating and cooling overseas for years, mini splits are finally gaining wide-spread adoption in the U.S. Why? They're easier to install, add more comfort, and save energy over traditional heaters and air conditioners. Soon, you'll see this same technology take over whole house heating and cooling.

2023: The hottest year ever

2023 was the hottest year ever recorded for our planet. And, since there's nearly-perfect correlation to man-made CO2 level increases and temperature increases, it would seem obviously important to mitigate or lower these levels. Solar, and, in Airspool's case, solar-powered air conditioning, is helping.

Is solar air conditioning worth it?

Solar-powered air conditioners are now gaining traction. More specifically, solar-powered hybrid (meaning that they can run using grid power, too) heat pumps (meaning that they can heat, too) are gaining traction, since they run using much less power, are much simpler, and need a much-smaller upfront investment that previous systems that required batteries, external voltage controllers, and inverters. But, are they cost justified? If so, when, where, and how are they cost justified?

Is solar air conditioning any good?

For most, solar air conditioners are now a wise investment, since newer technology in these units and lower costs for solar panels make them cost justified. The Inflation Reduction Act and environmental benefits are icing on the cake.

If Electric Utilities are Using Solar, too, Why are Utility Prices Always Increasing?

The price of solar modules keeps coming down. Western utilities in sunny states are paying less than $.02/kWh now, and they're buying more of it. So, why is just about everyone in the U.S., including in the West and other sunny locales, seeing increased pricing for their energy.

Using solar in the winter to run a solar-hybrid heat pump may have its challenges, but there's a huge upside

Using solar in the winter for heating may have its challenges... Shorter days? Check. Weaker sunlight because more of the sun's rays need to go through more atmosphere? Check Potentially your solar panels are at an angle of trajectory more suited for summer--something like your latitude minus 14 degrees? Check Snow on your panels? Check. Need for more BTUs, since for much of the country, going from, say, 35 degrees for heating to a setpoint of, say, 75 degrees is more of a lift than going down from 95 degrees in air conditioning to 75 degrees? Check But, solar panels are around 1/3% per degree below 77 degrees Fahrenheit more efficient in the winter, where their 1/3% per degree above 77 degrees less efficient in the summer. And, solar heating is free, so you can keep your house (or your cabin) heated all winter long, and if you come back (at least during the day), the house will be comfortable. #solarheat #diysolar #heatpumps

We're offering pre-charged, and pre-installed, line set by the foot. Why?

The last element of true DIY solar-powered air conditioning is adding the chance for users to get pre-charged, pre-installed line set by the foot. Why? Because if you're indoor and outdoor unit are too far away, you're going to need to call a contractor to lengthen the line set, even if you have quick-connect refrigerant lines. So, to avoid this expense and friction, Airspool now offers pre-installed, and pre-charged, line sets.

Draft Form 5695 for 2023

Draft of the as-of-now intended Form 5695 for 2023. Once this finalized, looks like you'll use line 1 for your solar equipment and labor deductions, and line 22a for your Energy Star-approved (e.g., Airspool MS12) equipment and labor deductions.

The Challenge of a Grid-tied Net-metered Solar Array During a Power Outage

What happens to solar panels that are grid-tied during an outage? Unfortunately, they're dead in the water. Or, dead on your roof, as it were. Your local utility requires your inverter shut off during such events to protect utility workers and equipment. Airspool can't run your whole house in such events, but at least you'll stay cool (or warm) as long as it's sunny out, since Airspool's panels are not tied to any utility.

Airspool's new Quick 'n' Easy revolutionizes mini split installation

You want a mini split, especially an Airspool solar-hybrid mini split, but you're afraid of the time, effort, and money the installation process may take. You're a good candidate for Airspool's new patent-pending Quick 'n' Easy unit that allows for connecting the indoor and outdoor units' refrigerant lines and communication control wires, along with the alternating current and DC solar power lines, in less than 5 minutes instead of the 5+ hours it takes most novices. No HVAC installation experience needed. And, literally, the only tool you'll need that Airspool doesn't provide in their Quick 'n' Easy kit is a drill. The Quick 'n' Easy is a true do-it-yourself mini split.

How often does an air conditioner need to be recharged?

Many people not familiar with air conditioning think that adding refrigerant to a system is a necessary part of maintenance. In fact, refrigerant should never need to be added. Adding refrigerant means you have a leak, since air conditioners are closed-loop systems. So, find the leak an seal it up, or get a new unit. Adding refrigerant eventually will likely not be sustainable, since through that same leak, air and dirt will be getting into the loop, and at times, the compressor will undoubtedly be running on too little refrigerant. It's a ticking time bomb.

48v battery solar air conditioners vs. 310v hybrid solar air conditioners

48v battery solar air conditioners and 310v hybrid solar air conditioners are both technological marvels, and offer many of the same advantages, but they operate quite differently.

Why is solar-powered heating harder to do that solar-powered air conditioning?

There are 5 primary reasons why running a solar-powered heat pump for heating is more difficult than running it for air conditioning. It all comes down to location, timing, and delta T.

The home of the future will be DC

Since so many of your appliances now run on DC power (computers, TVs, air conditioners (the good ones, anyway), and since solar creates DC power, it's beginning to make more sense to have one's home run on DC power. And, these guys from Purdue have created a model home to illustrate just that.

What is a 'solar ready' mini split?

What is a solar-ready or an ac/dc mini split? Quite simply, it's a mini split air conditioning heat pump that allows plug-in solar. The solar panel array just clicks onto the MC4 connectors on the outside unit. Cloudy or nighttime? These units are usually hybrid, so they also efficiently use grid power when not enough solar is available. Solar is always prioritized, though.

Yes, turn your air conditioner off if you're away (if it's not solar-powered)

Three engineers examined homes in hot dry AZ and hot humid GA on how to best manage the air conditioner when you're away from home. As expected?, the best savings came from turning it totally off if you work from work, especially if you have poor insulation.

Attn. Californians: Heat wave? Set your air conditioner colder and save money

California's grid operator and utilities are encouraging citizens to increase their energy savings by increasing the air temperature in their homes. Just say no! Get Airspool's ( solar-powered minisplit and set it to whatever temperature is most comfortable. It runs for free when it's sunny and very efficiently when grid power's needed.

Lots of folks in high-rate states like CA, MA, NH, VT, and ME still don't have air conditioners. Good solar air conditioner candidates.

The reasons can be debated, but the world, including areas that haven't had air conditioning in the past, are warming. Good candidates for solar-powered air conditioning.

Huge incentives for solar-powered heat pumps under the Inflation Reduction Act

Will it reduce inflation? That's debatable. But, there's a wave of huge free-money savings coming to anyone going solar or getting a heat pump--30% or more off.

Q: How often should my air conditioner run? A: Always, if it's efficient.

Traditional air conditioners are constantly turning on and off which i) isn't energy efficient, since their one-speed motors need 4-6 times more startup current than running current ii) wears down the motors, so they need more maintenance iii) create a larger temperature operating range, so users are less comfortable. Variable-speed motor, variable refrigerant flow (VRF) now efficient units run faster or slower depending on the heat load. Thus, they run slower, more efficiently with less motor wear and tear and with a tighter comfort range (deadband).

What the Inflation Reduction Act may mean to (solar-powered) heat pumps if passed

They have a deal! Biden, Schumer, and Manchin came up with something agreeable, and it's good news and big tax credits for the solar industry and (solar-powered) heat pumps. $369 billion for clean energy incentives.
