Geothermal Pros and Cons

Wednesday, August 28th, 2013

Geothermal systems are some of the most energy efficient heating and air conditioning systems on the market. G&S Heating, Cooling and Electrical offers a full range of services for geothermal systems and we wanted to put together a quick explanation of some of the pros and cons of these types of systems. Read on below and then give us a call if you have any questions or if you need North Seattle geothermal installation, repair or maintenance services.

North Seattle Geothermal Pros and Cons

Here is a quick breakdown of the pros and cons of geothermal systems.

Pros

  • Energy usage – Probably the most important benefit to geothermal system is that they allow homeowners to reduce the amount of energy that they have to buy from their utility company. Geothermal use the endless and free energy stored in the earth to provide your home with both heating and cooling.
  • Efficiency – The energy that geothermal systems get from the earth they use very efficiently. Geothermal systems are essentially heat pumps that move heat into or out of your home. Heat pumps are generally regarded as one of the most efficient heating and air conditioning systems on the market.
  • Year-long usage – While air-source heat pumps, like the ones in traditional central AC systems, cannot operate when the temperature outside gets too cold, geothermal systems can operate all year long.
  • Installation – Probably the most significant downside to geothermal systems is that their installation process can be intensive and complex. For ground-source geothermal systems, large trenches and holes need to be dug into your property. This means that certain property requirements need to be met and, if they are met, that significant excavation will need to happen in order to bury the ground loop. If your home doesn’t have enough space then you may not even be able to have the system installed in your home.
  • Leaks – With a ground-source geothermal system, you have to bury a long line of coils in your property. While it is unlikely, those coils can start to leak at some point. If this happens, repairing those coils can be difficult and time intensive.

How Does Geothermal Work?

Wednesday, August 21st, 2013

For homeowners that are looking to take the next step towards energy independence, a geothermal system is a great option. Here at G&S Heating, Cooling & Electrical, Inc. we offer a full range of geothermal services in Lynnwood, WA and we wanted to share a quick explanation of how these types of systems work. Give us a call if you’d like to schedule a preliminary visit with one of our technicians or if you have any questions.

Lynnwood, WA Geothermal Question: How to They Work

Geothermal systems are essentially heat pumps—they provide both heating and cooling by moving heat into or out of your home. In cooling mode, a traditional air-source heat pump will remove heat from your home and exhaust it into the outdoor air. In heating mode, it absorbs ambient heat from the outdoor air and moves it into your home.

Geothermal systems do the exact same thing except they use either the ground or a body of water instead of the outdoor air. For ground-source heat pumps, a long coil of pipes is buried in the ground where the temperature stays around 50° F all year long. For water-source heat pumps, this same type of pipe loop is submerged in a pond, lake or stream.

In cooling mode, the geothermal system will remove heat from your home and then exhaust it into the ground or into the body of water. In heating mode the process is reversed: heat from the ground or the water is absorbed by the pipes and then exhausted into your home to keep you comfortable.

As you may have gathered, homeowners need to have a certain amount of property or reliable access to a body of water in order to accommodate Lynnwood, WA geothermal installation services.

How an Expansion Valve Keeps You Cool

Friday, August 16th, 2013

In Woodinville, WA, air conditioning systems mainly work on hot days, then sit idle when our mild Seattle temperatures kick in. That means that faulty components can sneak up on you, alerting you to a problem only after a lengthy period of time has passed. It helps to understand the basic functions of each component, so that you can point a service technician in the right direction. Take, for instance, the expansion valve. What is it and how does it keep you cool? Keep reading to find the answers.

The expansion valve works as part of the system circulating refrigerant through your air conditioning system, as a part of the cycle that produces cool air. It’s connected to the evaporator coils and acts to regulate the amount of refrigerant that enters the coil. When the refrigerant reaches the valve, it’s in a highly pressurized liquid form. When the valve releases it into the coil, it evaporates: pulling heat from the surrounding air in the process. A blower fan then blows across the coils to push the cool air into the duct work and throughout your house.

Obviously, when an expansion valve experiences difficulty, it impacts your entire air conditioning system. If the valve won’t release the refrigerant into the coils, the air conditioning unit won’t do any cooling at all. Similarly, if it releases too much or too little refrigerant into the coils, the cycle won’t work the way it should. If the valve’s settings are too low, liquid refrigerant could enter the compressor or the suction line, creating a significant problem. (The compressor isn’t meant to compress liquid, only gas, which means that the compressor’s components can become seriously damaged by the liquid.)

A problem with the expansion valve needs to be diagnosed and corrected by a trained Woodville air conditioning technician. G&S Heating, Cooling & Electrical, Inc. handles air conditioning issues of all variety in Woodville and the greater Seattle area. We can examine your expansion valve and correct the settings, clean the unit or install a new valve safely and efficiently, with an eye on getting your air conditioning up and running again as quickly as possible.

3 Reasons You Should Consider a Mitsubishi Ductless Mini Split Air Conditioning

Friday, August 9th, 2013

Are you considering going ductless? Whether you already have an AC in your home or are starting from scratch as you construct the home of your dreams, you should consider all of your options. While forced-air distribution systems such as central air and heat pumps are standard among homes, ductless systems are growing in popularity due to their high energy efficiency, near-silent operation, and versatile cooling capacity. Whatever type of AC you select for your home, you need to make sure that it is installed by a professional so that it gives you exactly what you need. Call G&S Heating, Cooling & Electrical, Inc. today for detailed air conditioning services in Woodinville. We can make sure that everything runs smoothly with your new HVAC system.

  • Energy efficiency.One of the major perks of a Mitsubishi ductless mini split air conditioning system is the energy efficiency. Unlike forced-air distribution systems that require ductwork to circulate air throughout your home, a ductless system forgoes the intermediary and brings the cool air straight into the living space. The indoor air handler/evaporator unit sits directly in the living space, and multiple indoor units can be hooked up to a single outdoor compressor/condenser. A group of refrigerant, drainage, and electrical lines connect the two units.
  • Improved indoor air quality. For homeowners sensitive to allergens or who have respiratory conditions, indoor air quality is a critical point to keep in mind as you go shopping for your new AC. But its importance extends to everyone. Because our homes are so tightly sealed off to the outside elements, they can accumulate various airborne contaminants, and ductwork often provides a breeding ground. Ductless systems often cut down on indoor air quality problems because they avoid ductwork entirely. 
  • Built-in zoned cooling. Another benefit of installing a ductless mini split air conditioner in your home is that the multiple indoor units allow you to take greater control of how your home is cooled. Each unit can be controlled separately, so say hello to improve energy savings, and goodbye to family disagreements about the temperature in different zones of the home.

G&S Heating, Cooling & Electrical, Inc. is here to help install your ductless mini split air conditioning system. Talk to one of our friendly technicians today for further information. Call now for excellent air conditioning services in Woodinville, WA.
