It’s Time for Winter Heat Pump Maintenance

Monday, November 21st, 2016

The days are getting colder, and if you haven’t had your heat pump professionally checked yet, now is the time. Yes, even if you had it checked just a few months ago. Heat pumps need roughly twice as much maintenance as other climate control systems if they are to function properly. If they don’t receive this maintenance, they start to develop problems that would otherwise be completely preventable.

How to Tell if Your Heat Pump Needs Replacing

Monday, August 3rd, 2015

Heat pumps are great systems. They’re energy efficient, versatile, and can act as both heaters and air conditioners. As great as they are, though, they are not invincible. Eventually, you will have to replace your heat pump, no matter how well you take care of it. When that time comes, it’s a good idea to recognize the signs as soon as possible. That way, you can replace your heat pump before it breaks down on you completely. Read on for some of the more common signs that you need to replace your heat pump.

The Benefits of Installing a Heat Pump This Summer

Monday, June 8th, 2015

More people are starting to rev up their air conditioners as we move into the summer season. For some of us, though, it’s time to look for a new air conditioning system to replace one that can no longer keep up with demand. If you’re one of those people searching for a new system, there are other options besides central air conditioning to consider. Read on to learn more about one of those options: heat pumps.

The Cooling Benefits of a Heat Pump

Friday, September 26th, 2014

When you need a new air conditioning system, you may assume that your options for installation are limited. Many homeowners choose to replace their central AC system with a similar unit instead of taking the time to consider other types of systems. But there are many new units available on the market today, so it’s always best to ask a technician about the most suitable choice for you. In this guide, we’ll go over an efficient, multi-purpose cooling solution: the heat pump.

How a Heat Pump Cools Your Home

Heat pumps actually use the same refrigeration process as any other air conditioning system with the exception of one part, the reversing valve. In general, however, the key components for cooling are the same. Refrigerant first reaches the compressor, where it becomes a pressurized gas at very high heat before it moves through the rest of the system. Next, it moves to the condenser coil, where it changes into a liquid, a process which enables it to give off heat. It continues to the expansion valve, where it becomes a low-pressure liquid and then to the evaporator where it turns into a gas and absorbs heat. A fan blows cool air through the ducts, and refrigerant returns to the compressor to continue the process until your home is cooled.

The Benefits of a Heat Pump

The main advantage of the heat pump has to do with the reversing valve, which allows refrigerant to change direction. When you set your system to heating mode, refrigerant can take in heat from the outdoors and send it through the ducts, a feat that is not possible with standard air conditioners. Heat pumps offer a great alternative to furnaces for heating in areas with somewhat mild winters, which makes them perfect for both heating and air conditioning here in Lemoore. In fact, they are extremely efficient heating systems because they do not generate heat; they merely move it around. You can also find a heat pump with a high Seasonal Energy Efficiency Ratio (SEER) for efficient cooling as well.

3 Reasons to Consider Heat Pumps for Air Conditioning

Friday, September 19th, 2014

There are a lot of choices when it comes to choosing an air conditioner in Lemoore, CA. One option available to homeowners is the heat pump. Heat pumps can offer benefits that some other systems may not, but the best way to determine if a heat pump is a good choice for your home is to work with a trained professional. Shaw’s Air Conditioning has offered professional heat pump services for 10 years, and we can help you choose and install a heat pump that fits your cooling needs.

How Does a Heat Pump Work?

With the help of refrigerant, a heat pump transfers heat from one place to another. During the summer, the heat pump removes the heat and humidity and transfers it to the outside; during the winter, the heat pump absorbs the heat surrounding it and transfers it indoors.

Types of Heat Pumps

There are several types of heat pumps available:

  • Central heat pump – this type of heat pump is part of a traditional central air conditioning system
  • Ductless heat pump – this type of heat pump is part of a ductless heating and cooling system
  • Ground source heat pump – this type of heat pump is part of a geothermal system
  • Air-source heat pump – the most common type of heat pump, this heat pump can be used in several types of systems
  • Hybrid heat pump – this heat pump is used in climates in which a heat pump may need a back-up system due to consistent freezing temperatures

3 Reasons to Consider a Heat Pump

There are several reasons to consider installing a heat pump:

  • Heats and cools – a heat pump offers your home both heating and cooling. This is possible because of the reversing valve, a valve on the heat pump that allows it to reverse the flow of the refrigerant.
  • Good energy efficiency – heat pumps do not use fossil fuels; instead, they use a small amount of electricity to operate. This makes them very energy efficient.
  • Very versatile – heat pumps can work with several different kinds of air conditioning systems, including ductless and geothermal.

Heat pumps can be a great air conditioning option, but they are not for everyone. If you have questions about whether or not a heat pump is a good choice for an air conditioner, call Shaw’s Air Conditioning today and schedule your AC installation in Lemoore, CA with one of our cooling experts.

How Does a Heat Pump Actually Work?

Tuesday, November 19th, 2013

Here in Fresno, heating technology is largely a wintertime concern, when temperatures drop and nights get chilly. Heat pumps make an attractive option in our kind of climate: combining the features of a heater and an air conditioner into an all-in-one unit. That versatility works very well in the Central Valley, and heat pumps do their best work when temperatures don’t drop below 40 degrees, making them a very good fit for here in Fresno. But how does a heat pump actually work? We’ve provided a brief guide below.

Heat pumps operate according to the same basic technology that governs air conditioners, with a few little twists. The pump is divided into indoor and outdoor sections, which comprise a closed-loop system that constantly circulates refrigerant gas. In the summer, the gas begins in the outdoor section of the pump. It moves through a compressor valve, which subjects it to a huge amount of heat and pressure, then onward into a series of condenser coils which bleed the heat out of it and into the outdoor air. The process converts the gas to a liquid state, though it is still under a great deal of pressure.

From there, the liquid moves inside, through an expansion valve which releases a set amount of it into a set of evaporator coils. As the liquid evaporates, it pulls the heat from the surrounding air, cooling it in the process. The cool air is then blown into your home via a fan and the gas returns to the beginning of the loop to begin the process anew.

Most air conditioning systems perform some variation of the same process. With heat pumps, the cycle can be “reversed” in the winter, so that the indoor coil becomes the compressor coil and the outdoor coil becomes the evaporator coil. That allows you to warm your home instead of cooling it.

In towns like Fresno, heating technology of this kind offers both convenience and savings, since heat pumps use less energy than traditional HVAC systems.
