Hissing Sounds from Your Heat Pump

Monday, February 25th, 2019

heat-pumpThe heat pump really is a pretty tough heating system to beat. Even as recently as a few years ago, there was a lot of concern about how heat pumps would handle extremely cold temperatures. Today, there are heat pumps capable of heating down to those frigid temps that they get out in the northeast and the midwest. We don’t have winters like that to deal with, fortunately, so it’s safe to say that a heat pump is going to get you through our cold season effectively and efficiently.

Provided, that is, that your heat pump is in great working condition. Unfortunately, like any other heating system, there is no way in which to guarantee that you’ll never run into trouble with your heat pump. At some point, in fact, it’s all but guaranteed that you’ll need heat pump repairs. Not to worry, though. We offer heat pump repair and maintenance services throughout the Raleigh, NC area. Today, we’ll cover a warning sign of trouble to be aware of.

Does My Heat Pump Have a Refrigerant Leak?

Monday, February 12th, 2018

outdoor-unitHeat pumps are becoming more and more common in the residential sector. As homeowners look for more efficient and convenient ways in which to keep their homes comfortable throughout the year, the heat pump becomes undeniably attractive. This is thanks, in large part, to its use of the heat transfer process in heating one’s home. This process is thanks to the refrigerant cycle, which the heat pump is able to reverse in order to transfer heat into the home in the winter, and out during the summer.

For that reason, a refrigerant leak in your heat pump is of serious concern. The last thing that you want to do is to ignore the signs of a refrigerant leak, as doing so could lead to very serious problems developing with your heat pump. That means you need to learn how to spot signs of trouble with your heat pump to begin with. Today, we’ll be looking at some of those signs and helping you to better understand the function of the refrigerant in your heat pump. Contact our Cary, NC HVAC pros with any questions that you may have.

What Makes a Heat Pump So Efficient?

Monday, January 15th, 2018

cold-coupleHere in North Carolina, the heat of the summer season far outweighs the cold of our winters. While mild winters are definitely something that a lot of us love about living here, it is important that you are not lulled into a false sense of security. Sure, you may not be using your home heating system to the same extent that you are your air conditioner. That being said, it is still vitally important that you keep your heater in great working condition.

It is also very important that you choose your home heating system wisely. Living in a relatively warm climate such as ours actually gives you a benefit when choosing your heating system.

Some Possible Repair Issues for Ductless Mini Splits

Monday, May 22nd, 2017

ductless-mini-split-unitOne of the popular options for heating and cooling in modern homes is the ductless mini split heat pump. Rather than operate through a network of ducts connected to an indoor air handler and evaporator unit, ductless mini splits basically break up the indoor unit and blower fans and distribute it around the house in the form of mini air handlers mounted on the wall. If you’ve been in a house and seen something up on the wall that resembles a window AC, but it doesn’t go back through the wall… that’s part of a ductless mini split system. Those wall hanging units are hooked up to a single outdoor cabinet, creating a central heat pump system without ducts.

Winter “Problems” with a Heat Pump (That Aren’t Actual Problems)

Tuesday, December 27th, 2016

Heat pumps are increasing in popularity for homes, especially homes that don’t have connection to a natural gas line. Using a heat pump consumes much less energy than an electric furnace, making one an ideal choice for an all-electric household.

Heat Pump FAQ: Should a Heat Pump Have Frost on It in Winter?

Monday, December 14th, 2015

As the cold weather arrives, heat pumps in homes will switch over into heating mode. This means that the outdoor unit of the heat pump will draw thermal energy from the air and carry it indoors through refrigerant to release it indoors. If you notice that there is ice forming on the outdoor cabinet of your heat pump, it may seem abnormal, and potentially harmful to the heat pump’s operation.

Is a Heat Pump More Effective at Cooling or Heating?

Monday, June 1st, 2015

One of the main reasons that homeowners have heat pumps installed in the first place is because they provide a fantastic “two-in-one” package deal: an air conditioner and a heating system. It only takes a single adjustment on a thermostat to change a heat pump from heating mode to cooling mode and vice versa.

But are heat pumps equally effective at heating as they are at cooling? It’s a question people often ask, and we’ll address it below.

The Important Component That Allows Your Heat Pump to Both Heat and Cool

Monday, April 13th, 2015

Do you have a heat pump to take care of your air conditioning needs for the summer? There is one essential component that allows your heat pump to switch over from the heating job it has done for the last few months and start sending cool air through the vents. It’s called the reversing valve. Although there are a few other components that make a heat pump different from a standard air conditioner, the reversing valve is a key one, and understanding what it does will help you understand how a heat pump works in general.

If you want to have a heat pump installed or wish to schedule spring maintenance for your current heat pump, call on the HVAC professionals in Cary, NC: Raleigh Heating & Air. We have more than 20 years helping Wake County and the surrounding areas stay comfortable no matter the time of year.

The reversing valve and your heat pump

At the basic level, a heat pump is an air conditioning system. (Actually, it’s more accurate to say that an air conditioning system is a type of heat pump, but people in general are more familiar with the workings of an AC.) As with an AC, a heat pump cycles refrigerant between a pair of indoor and outdoor coils. A compressor provides energy to the refrigerant to transform it into a high-pressure, hot gas. The refrigerant then releases its heat through one set of coils and travels to the other to absorb heat before returning to the compressor.

When refrigerant leaves the compressor of a standard AC, it moves to the outdoor coils first. Here is where the reversing valve for a heat pump makes the difference: the valve sits on the refrigerant line where it exits the compressor, and depending on how it is set, it will either direct the refrigerant to the outdoor coils—acting like an air conditioner—or to the indoor coils. If it goes to the indoor coils first, it will release heat to the inside of the house, acting as a heating system.

One of the more common repair needs that a heat pump may require is to replace a busted reversing valve. If your heat pump won’t change over to cooling mode this spring, you may need to have the Raleigh Heating & Air team replace the valve. Give us a call and we will have your heat pump restored in no time at all.
