Single-Stage vs. Two-Stage Compressor Type

A single-stage heat pump uses a single-stage compressor that has two functions. You can either turn it ON or OFF when it reaches its maximum capacity.
It’s usually cheaper and if you’re on a budget, it’s a great option. However, this type of pump has a shorter lifespan and often doesn’t provide any dehumidifying features.

The two-stage heat pump which has a two-stage compressor and can either work at 100% capacity or at reduced capacity when necessary, is generally a pricier option. It will use less energy overall and do much better at controlling frequent temperature swings.
Another option is a variable speed model which is the most expensive but allows the pump to function on different levels. It’s usually best at delivering consistent temperature control.

Advantages of a Single-Stage Heat Pump

• Affordable
• Inexpensive installation
• Easy to use

Disadvantages of Single-Stage Heat Pump

• Only has one mode
• Shorter life cycle
• No humidity management
• Less efficient

Advantages of a Two-Stage and Variable Speed Heat Pumps

• Better noise management
• Uses less energy
• Humidity control
• Longer lifespan
• Better temperature swing management

Disadvantages of a Two-Stage and Variable Speed Heat Pumps

• More expensive
• Higher cost of installation
• Pricey maintenance and repairs

Understanding Energy Efficiency

Two different units measure the heating and cooling efficiencies of the air source ductless-split systems. The cooling efficiency uses SEER (Seasonal Energy Efficiency Ratio.) On the other hand, the heating efficiency uses HSPF (Heating Seasonal Performance Factor.) Most air source heat pumps have a minimum of 13 SEER and HSPF of 7.7. If you live in a warmer climate, paying attention to SEER is more relevant, but in some areas, a higher HSPF is preferred.

Heat pump sizing

When it comes to the best air source heat pumps, size does indeed matter. But a bigger unit doesn’t necessarily mean better for your home. Choosing a heat pump that’s too small or too big might mean your home won’t be heated properly and that your energy bill might even go up.

It’s best to talk to a HVAC professional who’ll help you determine the right size unit for your home. Factors like the foundations of the house, insulation, windows, and even thickness of the walls will be considered.

Noise Output

The compressors and fans inside your heat pump can often be noisy. That’s why it’s essential to check the sound rating of the heat pump you’re thinking of buying.

Did you know that a noise over 70 decibels can cause hearing damage over time? It’s best to look for a heat pump that maintains a noise level under that limit.

Defrost Control

Even though heat pumps are resilient and built to withstand all kinds of climate, frost can be particularly tricky. If it accumulates on the heat pump, it might affect efficiency. And then it will inevitably affect your comfort.

To make sure this doesn’t happen, always look for the demand-defrost control feature when buying an air source heat pump. It will ultimately increase the efficiency of the unit.

Advantages of an Air Source Heat Pump

There are many significant advantages of installing an air source heat pump in your home. If you’re an environmentally responsible individual, you’ll appreciate the fact that it has a low carbon footprint. Even though it primarily runs on electricity, you can also hook it up to a wind or solar power source.

Another great thing about it is that it has an overall longer lifespan. Did you know that there are heat pumps installed in the 80s that are still going strong today? But a more realistic expectation is somewhere around 20 years.

Finally, an air source heat pump means a simple and has relatively fast installation. You’ll need to consult an expert, but it’s usually a job that won’t take more than one or two days.

Disadvantages of an Air Source Heat Pump

No device is perfect, and that goes for the air source heat pump. Most of the disadvantages linked to the installation of the heat pump relate to it not achieving maximum performance in extremely cold weather.

In some cases, prior insulation will be necessary, and you’ll have to pay extra to have the underfloor radiant heating. Also, the fact that it runs on electricity, so it’s not entirely eco-friendly. They can also be a little too noisy, depending on the model you have.

Return on Investment

Undoubtedly, whether you’re installing a single unit or several, an air source heating pump costs a lot of money. It’s the kind of decision that no one should take lightly and that should be the right choice for you.

But it’s also a kind of an investment that offers a significant return. First, it will likely last you several decades. And within those years, your energy bill will be decreased by at least a third, and often even more.

It’s also a sustainable heating and cooling solution that’s an investment in a more environmentally-friendly future. Did you know that if you install an Energy Star heat pump by December 31, 2021, you’re eligible for a tax credit of 26%.

Here’s the thing – even if you buy the best air source heat pumps for your home, without proper installation, that won’t matter too much. And it’s not just about hiring the best contractor either. Even though built to last, heat pumps will require some attention and care from time to time.

That’s why it’s not about picking the single best unit, although the quality is paramount, but about an overall approach to choosing the best HVAC system for your home.

All of the seven reviewed heat pumps are great options, but not all of them will be the best for your needs. Cheaper options with low HSPF ratings are better for warmer climates. And remember to hire a high quality HVAC pro with solid experience and stellar homeowner reviews.

What is the best climate for a central air heat pump?

While modern air source heat pumps can perform exceptionally well under any climate, that doesn’t mean they’ll work the same anywhere.

Areas with moderate temperatures that don’t have frequent temperature shifts are the most efficient places for heat pumps. However, if you live in the part of the country with harsh winters where temperatures drop under 10F degrees, you may need a more powerful heat pump. Or an auxiliary heating solution.

How to Maximize the Efficiency of Your Heat Pump – Pro Tips

Like any HVAC system, air source heat pumps should be optimized and maintained correctly. Here are a few things you can do to make your pump more efficient.

Adjust Your Thermostat

Choose the temperature you’re most comfortable with and adjust it to the heat pump thermostat. It might be slightly different from the traditional thermostat, so the settings will probably be higher than what you’re used to.

Also, it’s best to avoid the “auto” mode. In the winter, have the “Heat” mode on, and in the summer, set it to “Cool”. That way, you’ll prevent the system from cooling your home on a sunny winter day or heating it on a chilly summer night.

Avoid Frequent Temperature Changes

Choosing the thermostat setting can be a struggle at home where everyone has a different temperature preference.
But avoiding frequent temperature shifts is much better for your heat pump. The steady temperature will ensure an even longer lifespan.

Clean the Dust Filters

Cleaning the dust filters in your air source heat pump will ensure that it’s always performing well. Vacuuming or rinsing them once a month is more than enough. You might notice the dirt yourself, or the indicator light might come on.

Regular Professional Maintenance

While cleaning the filters and fans is an important task you can do by yourself, other types of maintenance will require an expert.
When you should call someone, it will depend on your heat pump’s age and performance. But it’s a crucial chore that will ensure your pump always works efficiently.

Elevate the Heat Pump

If you’re living in a particularly rainy and snowy area, it’s advisable to raise your pump anywhere from 5-8” off the ground. That will allow for water drainage and keep the coils dry. Also, always make sure to remove any snow build-up from your heat pump unit.

      I live in MA, where winters are cold, and summers are hot, and I’m converting my whole house to Fujitsu Heat Pumps (ductless). And I will not have auxiliary heat, because heat pumps go down to -15F.

      I do have a backup heat, in case power goes down – my 30 year old furnace, that can run off two 5kWh LiFePo4 (lithium iron phosphate) batteries and a 3KW solar inverter/charge controller. I also have a gas fireplace insert which does not need electricity to run, as second backup. But as far ax auxiliary – I don’t need it. Plenty of heat from those heat pumps.

      However, central heat pumps are not powerful enough for extreme cold weather heating, and those DO need auxiliary heat.

      I worked on a Goodman 5-ton, and … uhmm … they are not terrible … however the new ones I’m not impressed as far as servicing them. Weird locations for high and low lines at compressor.

      Also a couple of weeks ago I was working an a 3.5ton goodman that was supposed to be 16 seer (based on model number and what customer had ordered), but on the unit, label said 14 seer, and then the evap coil was ALUMINUM – really??? they can’t do copper? And it is a 410A unit … so no, goodman is not that good 🙂
