Do Geothermal Systems Need Regular Maintenance?

Wednesday, August 27th, 2014

Geothermal systems are pretty ingenious: using the Earth’s natural, steady temperature below the frost line, a geothermal system provides both heating and cooling without the use of fossil fuels. But there can be some concern about maintaining a geothermal system due to its unique set-up. The truth is, the ground loop of a geothermal system does not need maintenance. In the case of a leak, dye is injected into the system, and when the leak is located, technicians dig down and seal it. The heat pump is the part of your geothermal system in Atlanta that requires maintenance, and Air Conditioning Experts has the trained technicians you need to do the job correctly.

Heat Pump Maintenance

Heat pump maintenance is similar to that of an air conditioning system. Here is a general overview of what to expect during a routine maintenance appointment:

  • Change of air filters
  • Checking and cleaning of coils
  • Check of refrigerant (if your system uses refrigerant)
  • Check of condensate array (tray and drain pipe)
  • Clearing of debris around heat pump
  • Thorough inspection of all wiring, connections, and electric terminals
  • Lubrication as needed (ball joints, motor components)
  • Inspection of fan and fan components
  • Check thermostat

Benefits of Heat Pump Maintenance

There are multiple benefits to scheduling maintenance for your geothermal heat pump:

  • Helps prevent future repairs –annual heat pump maintenance helps prevent repairs by taking care of the small things, like worn fan belts and frayed wiring, before they can blossom into big things. It also provides the opportunity to spot developing issues.
  • Increases energy efficiency – regular maintenance helps your system run optimally. Dirty components, low refrigerant levels and loosening fan belts can create stress for your heat pump. When a heat pump operates under stress, it uses more energy. By taking care of these small items, your heat pump can run optimally and use less energy.
  • Extend life of your heat pump – maintaining your heat pump helps reduce the level of normal wear-and-tear. This can help extend the life of your system.

The maintenance on your geothermal system in Atlanta doesn’t have to be complicated.

If it’s been a while since we’ve seen you and your heat pump, call Air Conditioning Experts today and schedule a maintenance appointment.

Types of Insulation Services Your Home May Need

Wednesday, August 20th, 2014

Good insulation in your home is key for keeping both your heating and cooling energy efficient. When your home lacks insulation, you’ll not only feel it with a lack of comfort, but you’ll see it in the form of high energy bills. Thanks to advances in the industry, there are several different types of insulation available for your home, but not all will be a perfect fit for your needs. Today we’re going to discuss the two types of insulation Air Conditioning Experts, Inc., carries, with a particular focus on blown-in insulation in Duluth.

Two Types of Insulation: Spray Foam and Blown-In

Two types of insulation in which we specialize are spray foam and blown-in. Both offer great benefits, but blown-in insulation is better for retrofitting.

Spray foam insulation has become very popular, and with good reason. Spray foam is insulation, but it is also an adhesive, so once it attaches to something, the bond is permanent.  It is extremely efficient, has good R-values and can reach cracks, crevices and nooks that are hard to insulate with larger, less flexible options. However, spray foam expands considerably when it hits oxygen – typically up to 100 times its size – so not only does it take care and knowledge to work with, it can be a little more difficult to use in a retro-fit situation.

Blown-in insulation, also known as loose-fill, is a mixture of small particles. These particles are typically made of fiber, fiberglass, foam, cellulose and mineral wool. All these materials are created from recycled waste, making blown-in insulation a very green option. Blown-in insulation is injected into the pre-existing walls of your home with a specialized hose via small holes that have been drilled between studs. Once the insulation of one wall is complete, the technician will move on to the next wall. Holes are re-covered with the original drilled-out circle reinstated as part of the wall; some wood glue and paint restore the wall back to normal.

Blown-in insulation can fill in crevices and nooks that aren’t reachable or easily insulated, but will not cover quite as tightly as foam insulation.

Good Insulation = Comfort and Efficiency

Insulation helps stop the transfer of heat, which is important year-round. Is your insulation keeping you cool in summer and warm in the winter? If not, it may be time to consider blown-in insulation in Duluth.

What Can Go Wrong If You Don’t Schedule Duct Sealing

Monday, August 18th, 2014

To some homeowners, ductwork can be the great unknown. This is because it isn’t visible and makes no noise (and shouldn’t). However, ductwork can be faulty or damaged, causing you and your air conditioner problems. A great solution for faulty ductwork in Roswell is duct sealing, but it’s important to schedule duct sealing with professionals, like the ones at Air Conditioning Experts, Inc., to ensure your ducts are sealed properly. Faulty ductwork can lead to multiple problems which will continue if your ductwork is left unrepaired. Here are a few types of problems that can arise:

Problems with Faulty Ductwork

  • High energy bills – air loss can be a big energy suck for your air conditioning system. In fact, faulty ductwork can account for up to 30% of total air loss in a system. This loss of cool air has to be compensated for by your air conditioner, and the only way to do that is to use more energy so that your system can cool more.
  • Uneven cooling – when certain vents are less functional than others due to cracks, holes or disconnections, it can result in uneven cooling, which presents as hot and cold spots throughout your home. Unless the vents are repaired, uneven cooling will continue, putting stress on your AC system and decreasing your indoor comfort.
  • Excess humidity – holes, cracks and broken seals in ductwork allow outside moisture into your air stream, which gets delivered directly to your home. Excess humidity can compromise comfort and promote the growth of mold, mildew and dust mites, which can be bad for allergy sufferers in your home.
  • Reduced indoor air quality – in addition to humidity, different particles can be sucked into the air in your ductwork via cracks and holes, reducing the overall air quality in your home. This can include dangerous “backdrafting” where exhaust fumes from combustion appliances enter into your indoor air.

How Does Duct Sealing Help? When your ducts are professionally sealed, holes and cracks are professionally repaired with mastic, a bonding agent, that closes the openings permanently. Sections are bound together with metal bindings, and collapsed sections of ductwork are either repaired and reconnected, or replaced. Duct sealing in Roswell can restore your energy efficiency and comfort, while also improving your indoor air quality.

When Is Spray Foam a Good Choice for Insulation?

Monday, August 11th, 2014

Insulation is important to your energy efficiency all year. It helps keep heat from transferring out of your home in winter and blocks it from entering your home during summer. Over the last few years, spray foam has become a popular choice for homeowners either as stand-alone insulation or in combination with layered fiberglass insulation. Since 1995, Air Conditioning Experts, Inc. has seen the benefits spray foam has given our customers. If you’ve been thinking about adding spray foam insulation to your Atlanta home, here are some things to consider.

Types of Spray Foam

There are 3 main kinds of spray foam:

  • Open cell, low density – used in larger insulation applications
  • Closed cell, medium density – used as air sealant in combination with fiberglass insulation
  • Closed cell, high density – used in roofs and other areas needing high levels of insulation

How Spray Foam Insulation Works

Spray foam insulation expands considerably – up to 100 times of its original size – when it meets the oxygen in the air. Spray foam is an adhesive, so it forms an airtight seal once it dries. It can take anywhere from 24-48 for spray foam to cure (harden), depending on what type you use.

Benefits of Spray Foam

There are several benefits with spray foam that you may not get with other kinds of insulation:

  • Very energy efficient – average R-values are approximately 6.0 per 1” of thickness
  • Blocks outside air and moisture – airtight seal keeps out unwanted air and moisture
  • Improves comfort levels – sealing aspect of foam helps eliminate air loss, improving comfort levels
  • Stable – spray foam is permanent and won’t sag as fiberglass can
  • Helps reduce allergens – spray foam cuts down on particle infiltration from the outside
  • Reduces stress on your air conditioning and heating – with an energy efficient home, your AC won’t need to work as hard to cool
  • Reaches hard-to-get-to places – because of its flexible nature, spray foam can reach cracks and crevices you may not be able to reach with fiberglass insulation

Always Use a Professional for Spray Foam Application

Spray foam is a great insulator, but it can cause problems when mishandled. First, incorrect application may not result in the covering of all cracks and crevices, reducing the efficiency of the insulation. Second, if too much foam is applied, damage to studs and walls can occur. Third, there may be some clean-up involved with spray foam that someone inexperienced may miss. The bottom line: hire professionals for your spray foam insulation installation in Atlanta.

How to Tell It’s Time for Water Heater Replacement in Atlanta

Monday, August 4th, 2014

Water heaters contain few moving parts, which helps their longevity. However, the constant contact and pressure from water means these appliances will eventually wear out: most water heaters have a manufacturer’s lifespan estimate of about 15 years. Around that point, you can expect to notice problems with a water heater that will warn you it’s time to have a new one installed.

We’ll look over some of the more common signs that your current water heater is approaching the end and needs to be replaced before you suddenly find yourself without any hot water. If you feel unsure about your current water heater, call professional plumbers to examine the system and offer expert advice. If the time has indeed come for replacement, the plumber will help you select a new unit and install it for you.

Air Conditioning Experts, Inc. handles water heater replacement in Atlanta, GA. With our almost 20 years of experience serving the greater Atlanta area, we should be one of your top choices for home service.

Signs you should replace your water heater

  • A drop in hot water volume: Does it seem that the hot water runs out earlier than it once did during the morning round of showers? This could indicate a repair need (such as a broken dip tube or a burnt-out heating element), but for an older system, it usually warns that the heater simply can no longer keep up with the standard demand.
  • Reduction in water temperature: Instead of the water volume decreasing, the temperature of the water decreases. A dying water heater will struggle to keep up the heat level expected of it, so when it seems the water is never warm enough for your comfort, you should call for a plumber to investigate the system.
  • Rust from the taps: When rust starts to form inside the tank of the water heater, it often means the system is finished. One of the ways that you will discover this is from reddish discoloration in the water that comes out when you turn on a hot water tap. Look over the tank form the outside, and if you spot rust and corrosion along the bottom of the tank, then it is definitely time for a new installation.
  • Leaking tank: The water tank should not start to leak, and if it does it will warn of serious corrosion issues inside it. Patching up these leaks is probably not enough; the system is too old.

Water heater installation is an easy job when you hand it over to professionals with many years of experience.  Air Conditioning Experts, Inc. can offer you excellent hot water heater replacement in Atlanta, CA.
