Most Commonly Asked Questions about Heat Pumps

Friday, February 25th, 2011

If you’re thinking about buying a new heat pump for your home, chances are you have some questions about these types of products and how they work. In fact, because these types of home comfort systems are relatively new to a lot of people, there are a quite a few misconceptions out there about how effective and efficient they can be.

Recently we’ve gotten some good questions from our readers, so we thought we’d like to pass along the answers so that others can benefit from the information as well.

If I Buy a Heat Pump, Do I Have to Buy an Air Conditioner Too?

That heat pumps are only able to heat your home is probably one of the biggest misconceptions about this type of equipment. Heat pumps work by extracting heat from the air in one place and transferring it to another. That means that in the winter, your heat pump is able to heat your home by taking heat from the outdoor air and moving it inside.

However, in the summer, the heat pump is able to do the same thing only in reverse. When you switch on your heat pump’s cooling function, it will be able to take the heat out of your indoor air and transfer it outside. In this way, the same heat pump system can keep your home warm in the winter and cool in the summer without you needing to purchase an air conditioner or other supplemental comfort systems.

If I Choose a Heat Pump System, Will I Also Need to Install Supplemental Heat?

That depends on what the climate is like where you live and how warm you like to keep your home. In general, heat pumps can keep any home comfortable as long as the outdoor temperature is above 32°F or so. If the temperature outside drops below that, you may want to have some type of supplemental heating system just in case. However, a heat pump will still be able to provide some warmth at these lower temperatures and you may be able to keep yourself comfortable with a simple space heater or too.

Also, remember that these colder temperatures are most common at night when you would probably have turned your heat down anyway. As long as you live in a relatively moderate climate, heat pumps can do a great job of keeping your home comfortable all year long.

When Should You Replace Your Existing Heat Pump?

Friday, January 7th, 2011

Nobody wants to think about having to replace a home heating and cooling system. It’s a big job and a new system probably won’t come cheap – not if it’s worth buying anyway. But in the end, you’ll be better off replacing your heat pump sooner rather than later if you start noticing signs that it may be on its way out.

So what are these signs? Well, they’re actually pretty easy to recognize if you know what to look for. For instance, if your heat pump is suddenly making more noise than it used to, there’s a good chance that something’s going wrong inside. This may only require a minor repair, but if minor repairs like this become a regular occurrence, you should start seriously thinking about looking around for a new system.

The cost of even minor repairs will certainly add up quickly over time, and you’ll have to seriously think about whether it makes financial sense to continue to repair an older system rather than simply replacing it with a new one. Chances are that you’ll have to invest in a new one anyway, and the sooner you do it, the less you’ll have paid for repairs to a system you were just going to get rid of anyway.

Also, if you’re starting to notice humidity problems in your home or if some parts of your house are being kept warmer than others, it may very well be a sign that you heat pump isn’t working like it should. Again, this can sometimes be rectified with repair work, but especially if your heat pump is 10 years old or more, it probably makes more sense to replace it.

Another item to keep an eye on when you’re worried about how well your heat pump is working is your monthly energy bill. If you notice a sudden or even a gradual but steady increase over time that you know isn’t a result of an increase in energy prices in your area, you should suspect that your heat pump isn’t working like it should.

Even if it’s still keeping your home at a comfortable temperature, the fact that your heat pump is using more energy to do it is a sign that there’s something wrong with your system. Plus, newer systems are generally more energy efficient anyway, so you’ll be making up for the initial investment of purchasing a new system when you start paying even less on your monthly energy bills.
