What It Means When Your Heat Pump Won’t Switch Modes

Monday, October 17th, 2022

technician-working-on-furnaceFall is in full swing and temperatures are enjoyable and cool. But with winter just around the corner, temperatures will soon be dropping even more. You need your heater or furnace to work right every day around the clock so that your home and family are comfortably warm. But it’s not uncommon for homeowners to switch their heat pump from cooling to heating only to find out that their heat pump won’t switch modes. 

What happens then? A broken heat pump is the last thing you want to deal with, but it’s a possibility. Remember that skipping regular heat pump maintenance can increase the chances that your heat pump won’t switch modes from cooling to heating – and it’s not too late to schedule maintenance for this season. If your heat pump won’t switch modes, give us a call for heat pump repair and our team can get your heat pump working again.

Is Your Heat Pump Ready To Switch To Cooling Mode?

Monday, May 16th, 2022

sun-and-snowflake-animationIt’s been a long, cold winter, and while you may be ready for warmer temperatures, that doesn’t necessarily mean your heat pump is.

Many homeowners appreciate the fact that their heat pump has the ability to both heat and cool their home; however, what they may not realize is that this type of system isn’t always able to change modes so seamlessly. In fact, an inability to switch between heating and cooling mode is one of the more common troubles heat pumps can run into.

In this article, we’ll review some common causes of this malfunction, and what you can do to address it.

How Is Your Furnace Heat Exchanger Holding Up?

Monday, September 26th, 2016

Were you aware that the heat exchanger is the component that allows your furnace to function as a heater? Is yours in good shape? If you haven’t had maintenance done yet to prepare for fall and winter, then you are doing yourself a disservice.

A crack developing along the heat exchanger is a significant safety concern when it comes to a gas furnace. Should you discover you have this issue, you’ll want to call for immediate professional repairs. But why is it so important? Keep reading to learn more. (more…)

Why Your Heat Pump Won’t Heat

Monday, January 18th, 2016

It’s pretty unpleasant to turn on your heat pump expecting warmth and be instead greeted with a blast of cold air. Heat pumps are highly valued for their ability to switch between heating and cooling modes, but occasionally they can lose this ability. If your heat pump is stuck in cooling mode this winter, there could be a couple of different reasons why. Let’s take a look at those reasons now. (more…)

Heat Pump Issues to Be Aware of This Winter

Monday, December 28th, 2015

Heat pumps have a lot of advantages over other traditional heating systems, thanks to their unique construction. However, they also have to deal with a lot of problems that other heating systems don’t, and for the same reason. If you’re using a heat pump to keep warm this winter, you should be aware of these issues. Read on to find out more about common heat pump problems, and when to call for repairs. (more…)

Keep an Eye Out for Heat Pump Ice This Winter

Monday, December 14th, 2015

If you’re using a heat pump to keep warm this winter, you will probably notice ice forming on the outside unit at some point. Ice on the outside coil isn’t normally a problem, and is actually quite common. However, you should still keep an eye on it in case it starts to get out of control. Read on to find out more about heat pump ice and the effects it has on the system. (more…)

Heat Pump Tip: SEER vs. HSPF

Monday, August 20th, 2012

When it comes to Bellevue heat pumps, there are two different ratings you’ll often see – the SEER and the HSPF. So, what does each of them mean and which rating is more important when purchasing your new device? Here are a few things to consider:

 SEER

The acronym SEER is short for “seasonal energy efficiency rating” and is used most commonly to measure air conditioner efficiency or in this case, the cooling capacity of your heat pump.

 HSPF

The HSPF is short for “heating seasonal performance factor” and is a measurement of how efficient the heat pump is in producing heat during the cooler months of the year.

 The Difference Between the Two

Every heat pump will have both of these ratings, allowing you to see how efficient each is. This is important because you need to know for certain how well your heat pump will perform under certain situations – both in the winter and summer.

However, if you live in a colder climate where the summer rarely calls for air conditioner, your focus should be on the HSPF first. And if you live in a warmer climate where your heating needs are minimal, the SEER is most important. Another thing to consider is your supplemental heat. If the cost of your supplemental heating system is high, you’ll want an HSPF that is as low as possible to balance it out.

 Choosing an Efficient Heat Pump

Heat pump efficiency directly impacts the price of the device you purchase but is almost always worth the difference. The key is to find a device that provides what you need based on where you live. Keep in mind as well that, like most HVAC upgrades, you won’t immediately recoup the cost of the device in your energy savings, so if you plan on moving soon, you should purchase a more affordable device now and upgrade later.

Purchasing a new heat pump for your Bellevue home is an important step in making it more energy efficient. If you are unsure which rating you need or how to analyze their meanings, contact a professional to learn more.

How Can Heat Pump Reversing Valves Help Heat Homes in Kirkland?

Monday, June 11th, 2012

As conventional energy resources dwindle and become more expensive, alternatives increase in popularity.  Heat pumps in Kirkland, like the natural heat they harness, are fast rising to the surface.

Tapping the stored energy of the greatest solar collector in existence, ground source heat pumps (GSHPs) are electrically powered systems that tap the earth’s relatively constant temperature to provide cooling, heating, and hot water for homes and commercial buildings. Simple, efficient and abundant, heat pumps are best used in moderate to hot climates where the differential of temperatures is not extreme.

In General

Functioning on the same principle as refrigerators, the heat pump uses a liquid to absorb heat as it turns into a gas and release heat as it returns to a liquid state. During the summer, the heat pump operates as a standard central air conditioner, removing heat from the house and venting it to the outside.

In the winter, the heat pump reverses this process, extracting heat from the cold air outside and releasing it inside the house. The heat pump is very efficient when the outside temperature is around 45 degrees Fahrenheit to 50 degrees Fahrenheit, but it becomes less efficient as the temperature drops.

The Heart of the Matter

The reversing valve in the heat pump switches the process from absorbing heat from the inside to evacuate outdoors like an air conditioner to extracting heat from cold temperatures outside and redistributing it indoors.  The thermal energy at play is the natural force of heat to move toward cooler temperatures, releasing energy in the shift.  Heat pumps take care of both and the reversing valve controls the direction of the flow.

The reversing valve has two states of operation: relaxed and energized.  In the relaxed state, the heat pump can be programmed to introduce either heated or cooled temperatures into the conditioned space, depending on the direction of the flow of refrigerant through the closed loop.

By applying a 24 volt charge of AC current (a low voltage typically used in HVAC systems), the valve becomes energized and reverses the flow, producing the opposite conditioning.  The reversing valve may be driven by the heat pump through the use of a control board or directly by a thermostat.

As energy resources rapidly change in cost and supply, heat pumps utilizing geothermal energy are looking like a viable alternative in today’s market.  To learn more about this heating option please call Sound Heating
