What happens inside this outdoor unit is a very basic state change of the refrigerant inside the air conditioning unit. The refrigerant that changes from a liquid to a gas inside the indoor coil moves to the outside where the compressor compresses the gas under high pressure. When this happens the gas also becomes very hot. The hot gas then leaves the compressor to start traveling through the many feet of tubing in the condenser coil. As the gas cools it changes back to a liquid form going back indoors to start the cycle all over again.

Big problems start when the condenser coil becomes so blocked up with dirt that the hot gas in the condenser coil does not cool enough to change the hot gas back to a liquid form. If this happens the cooling process does not happen and then air conditioner runs but is not cooling. The compressor starts to get very hot and the ultimate result will be the death of a compressor. For these reasons the condenser coil must be kept clean and free of debris at all times when the air conditioner is running. Cleaning the coil is a fairly simple process, Here are a few guidelines to follow when doing this.

To clean the coil a few simple tools are needed. A garden hose with a nozzle, wrenches to remove the condenser fan, a garden sprayer for applying the cleaning solution. The first thing is to disconnect the power to the outdoor unit. There should be a disconnect switch of some type near the condenser. Then remove the fan from the condenser unit. Usually this will be the top of the unit. The fan can usually be laid aside carefully without disconnecting the wires to the motor. Carefully wet down the coil with the garden hose. If you have very high pressure water where you live be careful that the water pressure does not bend over the fins on the coil. These are very thin and fragile. If they get bent over the air will not be able to freely flow through them. Using the cleaning solution from the garden sprayer, coat he inside and the outside of the coil. Let the solution work on the dirt build up before washing it off. If you use a foaming type coil cleaner then let the foam cook the dirt out of the coil. Then use the garden hose to wash the dirt out of the coil. I often work from the inside spraying out through the coil. This is the reverse of the usual air flow and it washes the dirt out easier. Rinse the coil with water till it is clean with no more dirt or cleaner coming out. Replace the fan and start the unit back up.

The cleaning solution for the condenser coil can be any good household cleaner. Many automotive type radiator cleaners will work well. For very dirty condensers it would be good to buy a foaming coil cleaner made specifically for cleaning condenser coils. A local plumbing and heating supply house should stock coil cleaning solutions. Most of these solutions are very strong chemicals. Be sure to wear gloves and eye protection when working with them.

By keeping your air conditioning condenser coil clean, you will help to have your air conditioner running at the best efficiency possible. A clean condenser coil is one of the easiest ways to save electric while running your central air conditioning system. A clean coil will allow your compressor to run cooler and help it to last longer. Your condenser coil should be thoroughly cleaned at least once a year. If in you live in very dirty areas like along a dirt road you may need to clean the condenser coil more often. Also do not do things that would clog up the coil. Blowing grass clippings into the condenser coil is one common thing that happens. Keep shrubbery from growing into and around the condenser coil. This stops the air flow to the coil. Large flowers planted too close to the coil can do the same thing.

As you can see there are many things that can cause your air conditioner to work harder and cost you more money. By taking a the time to look over things and give it a cleaning you can save a lot of money.

Unexpectedly high heating or cooling bills Inconsistent heating or cooling, or rooms with unusual conditions such as:

Stuffiness or large amounts of airborne dust and particulates

Difficulty maintaining consistent and appropriate levels of heating or cooling in particular rooms or areas of the house

Ducts that are visibly damaged, loose, detached or missing

Un-insulated or poorly insulated ducts in unconditioned areas of your home, such as crawl spaces, unfinished basements and attics or garages

Leaky ductwork can also be dangerous if carbon monoxide or other harmful exhaust gases escape into your home. That’s why it’s important to have your system assessed regularly by a licensed heating and air conditioning professional in your area.

A ductwork sealing project should include the following:

Check the entire length of the ductwork system for potential leaks or other problems.

Repair or replace any damaged ductwork sections.

Reconnect loose sections and make sure they fit together tightly.

Straighten out any bent or kinked ducts.

Seal holes, cracks or openings in the ductwork.

Ensure secure duct connections at all registers and vents and at the HVAC unit.

Make sure all connections and joints are sealed with mastic which is a specialized sealant for use on ducts, or with metal tape.

Avoid using standard duct tape as the adhesive can fail over time. Insulate ductwork with rigid fiber board or the standard roll insulation.- This helps prevent energy loss through the metal of the ductwork itself.

A licensed HVAC professional can provide a full range of HVAC work that produces the results that heating and air conditioning customers can rely on. Contact one today for more information on the benefits of duct sealing or to schedule a professional duct evaluation and sealing.

Smart Thermostats from Ecobee

Homewerks Radio Wireless Thermostat with Wi-Fi

Honeywell Prestige 2.0 Comfort System.

The basic idea behind each smart thermostat is that they tend to learn about the user’s behavior and fine tune its performance according to ambient temperature, humidity and motion. Basically, the idea behind the thermostat is to control and monitor the temperature of the surrounding for efficient utilization of energy. For serving the purpose, three categories of thermostats are there:

Regular thermostats: are similar to a control panel for an air conditioning and heating devices using which, the temperature of the room or enclosed surrounding can be controlled.

Programmable thermostats: allow a user to set the temperature for each time of the day and the device, then changes the temperature according to the preset values.

Smart thermostats: are the ones which inherit the property of learning from the integrated electronic chips and processors that understand the behavior of the user and surrounding conditions. After the reading and storing the particular values, it alters the behavior of the device intelligently.

The concept of smart thermostat can be considered as one of the successful examples of the concept of clean technology. Clean technology is an idea of implementing technology based solutions in different areas and tasks for high level of energy efficiency. High energy efficiency and energy optimization assists in building a cleaner environment and contributes in resolving major environmental issues like global warming.

Smart thermostats are integrated with the most popular solutions of computer technology i.e. with internet connectivity capability and communication standards for smartphone applications. These services allow users to control and monitor their cooling or heating device from a remote location and also help them in managing their energy consumption, efficiently.

One of the heating and cooling efficiency guidelines of a famous government agency included programmable or smart thermostats as one of the several ways of saving energy efficiently. If realized in terms of money, a programmable or smart thermostat can save up to $180 per year of energy for each home user. This shows that deploying a smart thermostat not only builds a cleaner environment but is an economic way of energy consumption as well.

it will makes your house cool in the summer and hot in the winter.
is working correct with seals so the air can’t into the duct system.
makes your home feel comfortable.

These three aspects are important. The location of the ductwork is also key because it should be placed between floors of a house with more than one floor. Supply outlets should be in the kitchen or bathroom because they need to away from the exhaust vents.

When a duct system is installed in the correct way, they will probably be around 80% efficient. This will definitely save you money on your energy costs.

You should let our HVAC team take a look at the way your ductworks are designed. It doesn’t matter how much you think you know about your homes ductworks, you may need the help of a professional. If we find a problem, we will fix the problem immediately.

There are fairly good chances that you didn’t design the the ducts in your house because they came with the home when you bought it. However, when your having a problem with your ducts, you may want to do some research into the three different kinds of ducts. This could lead to a better ductwork system put into place by our Las Vegas Air Conditioning team.

There could be a few reasons that might explain why your ducts aren’t working probably. The first issue is that meandering canals could possibly need better insulation if they are installed at all. A lot of ducks aren’t meant to be 100% effective; they are usually around 60 to 75% effective. The most common problem when it comes to ineffective ducts is the way it was designed.

You may notice that there’s a problem in a few ways. When a room is extremely chilly or extremely hot, there is probably an issue. Sometimes the room can feel extremely stuff as well. Consult your energy bill to see if your suspensions are backed up by a high energy bill.

1. It makes your energy bill lower each month. When your ducks are leaking air, you are losing at 20% or more of the air to the outdoors. By sealing the ducts, you will be able to use all the air that you have paid for within your home and not loose that air to the attic or to the outdoors.
2. It will make the air quality within your home better. There is vacuum made when air is leaking out of the desired rooms. This makes all the unwanted things within your home such as pollen and dust leak out into your home with the air that’s being moved. Since you have to break in this junk with the air, sealing off your ducks will make your health improve. Since you breathe the air, sealing the ducts promotes better health.
3. It will promote safety within your home. Besides dust and pollen, the moving will also pick on gases from appliances that use fuel. It will drag the gases through the walls or floors of your home. If aren’t careful, you may let these gases be in the breathable air of your home.
4. You will feel more comfortable within your home. When an air conditioned room feels too hot, it’s probably the cause of a leaking duct. If the duck is leaking, it will be extremely noticeable during the hotter months. Once the problem is fixed, the customer will pay less and be more comfortable.
5. You won’t need to use as much electricity. Once the deals are sealed, you won’t have to use as much electricity as before.
