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.

Some Benefits of Heating Maintenance You May Not Have Realized

Monday, November 16th, 2015

During the fall is when professional HVAC companies urge customers to arrange for regular maintenance for their heating system. This is vital for making sure that a heater will run with as little chance of repair issues or failures as possible. It’s simply a good “insurance policy” against getting trapped in a chilly and uncomfortable house during one of the coldest days of the year. It also keeps heaters running at their most energy efficient.

There are many benefits to routine fall maintenance for heaters, however. We’d like to look at a few that may not have occurred to you before.

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.

Does My Geothermal Heat Pump Need Annual Maintenance?

Monday, April 6th, 2015

If you have a geothermal heat pump (a.k.a. a ground-source heat pump) keeping your home cool in summer and warm in winter, then you already have one of the best comfort systems available at work for you. Geothermal heat pumps are energy-efficient, dependable, beneficial for the environment, and have lifespans that leave standard heat pumps, air conditioners, and furnaces far behind.

However, don’t let the long service life of a geothermal heating and cooling system trick you into thinking that you don’t need to take care of it with regular maintenance. Just as with a standard heat pump or other comfort system, your geothermal heat pump must receive an maintenance inspection from trained professionals twice a year, once in spring and then again in the fall.

If you are looking for a geothermal specialist in Wake Forest, NC or elsewhere in Wake County, give Raleigh Heating & Air a call today.

The importance of regular geothermal heat pump maintenance

Here is something that is important to keep in mind with a geothermal heat pump: even though it uses ground loops to release and absorb heat, the components inside the house are very similar to those of an air source heat pump. This means it needs the same type of regular care that standard heat pumps need. During a maintenance visit, the technician checks over the components of the indoor unit of the system to see that the coils and motors are clean, all mechanical parts lubricated, the air filter unclogged, the condensate drain clear, and the electrical connections are tightened.

There are a few special checks a maintenance technician must do for a geothermal system, such as looking over the manifold and the heat exchanger where the antifreeze in the loops transfers heat to or from the indoor refrigerant. If you have an open loop configuration, the technicians may occasionally give the loops an acid flush to remove deposits that can build up in them.

This routine maintenance serves the same purpose for a geothermal heat pump as it does for any comfort system: prolong its service life, protect its efficiency, catch malfunctions, and prevent future repair issue.

A geothermal system is a major investment, and you want yours to last as long as possible so that you reap the greatest benefit from its energy-efficient performance. Raleigh Heating & Air is here to help you with the regular maintenance that will see that your geothermal heat pump lasts for decades.

Heat Pump Tip: Making Sure Your Heat Pump is Ready for Summer

Monday, March 4th, 2013

You rely on your heat pump to cool your home all summer long. Because your heat pump works throughout the year, getting regular heat pump maintenance in Raleigh, NC is critical to ensure successful operation. Here are a few of the things that you can do to make sure that your heat pump works well.

Remember that major maintenance duties and even minor repairs should be carried out by a heat pump expert. The following components should be inspected and cleaned:

  • Air filters. This is one of the most important parts of your heat pump system. While it protects your system from dust, dirt and other foreign debris, it can become clogged and can actually prevent the passage of cool air into your home.
  • Drain line. As with any drain, if it gets clogged, it prevents the passage of wastewater outside the system. This can lead to water leaks which might cause water damage in your home or on your property.
  • Fan blades and fan enclosure area. To work effectively, your heat pump’s fans must rotate freely without restrictions. It’s surprising how much a layer of dust and other debris can inhibit the fan components.
  • Outdoor condenser unit. Making sure nothing obstructs the outdoor condensing unit. This is where heat from inside your home gets exhausted to the outside. The effectiveness of the heat transfer process can be severely disrupted, if leaves, grass or dirt impede the airflow.
  • Indoor coil. If your coil is dirty, it will not adequately cool the air as it moves through its cooling cycle, and will therefore have to work harder.

The best way to make sure your air conditioning system is ready for summer is to get routine heat pump maintenance in Raleigh, NC. Only by ensuring your heat pump and its components receive the best possible professional care, can you expect their consistent performance all summer long. At Raleigh Heating & Air, we are committed to the comfort of our customers. Call us today!

Getting the Most from Your Heat Pump

Monday, February 11th, 2013

With energy prices constantly on the rise, homeowners everywhere are looking for every opportunity to reduce their energy consumption. If you have a heat pump in your home in Raleigh, then you are likely enjoying comfortable heating and cooling all year long. But if you’ve started to notice that your utility bill is increasing, you probably are interested to know why and how to reduce it. At Raleigh Heating & Air, we want our customers to be comfortable in their homes and to get good efficient heating and cooling from their heat pumps. Here are some of the ways that you can get the most out of your heat pump in Raleigh.

Regular Heat Pump Maintenance in Raleigh

Perhaps one of the best ways to get the most out of your heat pump is to get it regularly maintained by a professional contractor in Raleigh. There are huge benefits for homeowners who have their heat pumps regularly tuned up. During regular maintenance visits your heat pump technician will thoroughly inspect and clean every aspect of your system. This will allow them to find any small issues and repair them before they cause your system to start performing poorly. This can potentially increase the efficiency of your system. It might also be able to extend the life of your heat pump. Small problems are often the cause of homeowners needing heat pump replacement.

Thermostat Upgrades

Another great way to potentially improve the performance of your heat pump is to upgrade your thermostats. The thermostats in your home control when your heat pump turns on and for how long. If you were to upgrade to a web enabled thermostat you may be able to gain more control over your home’s energy consumption. Web enabled thermostats connect to your home’s internet connection. You can access them from anywhere in the world using a computer or your smartphone. You can control when they turn on and when they turn off. They can also send you email alerts when your home starts to use too much energy.

Blower Door Testing

Blower door testing is a great way to find out exactly how efficient your home is. During these types of tests, technicians will seal off your home and attach a blower to your front door. This will create pressure in your home and allow us to find out exactly where any leaks are.
