Does Your Air Conditioner Need Replacement?

Tuesday, March 20th, 2018

air-conditioning-replacementSpring will officially be here this week, and summer will be along before you know it. As the weather warms up, we’re going to be using our air conditioners more and more often, until we’re running it all day every day to counteract our scorching Arizona heat waves.

If your air conditioner is on its last leg, now is the time to get it replaced. You have plenty of time to schedule a replacement session, and your new air conditioner will save you a great deal of money and worry.

Outdoor Air Conditioning Components for Tempe Homes

Monday, May 21st, 2012

As long as all the parts are working well, air conditioning in Tempe is a modern convenience we can easily take for granted and overlook. Cool air makes our lives simply better, but is a complicated process based on an old theory and modern technology.

No matter the size, in every unit, the basic purpose is one of extracting heat from the conditioned space and moving it to the outside, leaving cool air in its place. This process easily divides into indoor and outdoor components.

Air Conditioning 101

Utilizing the basic principal of thermal energy that heat gravitates toward cooler temperatures, compounds known as refrigerants travel through a closed looped system, repeatedly transforming between liquid and gas forms. Chosen for their ability to rapidly change at low temperatures, they alternately absorb and release heat along the way.

Having expanded to a vacuous state with plenty of room between molecules to absorb heat, the refrigerant is compressed tightly, condenses back into liquid form and releases the heat to the outdoors.

In the Box Outside

Placed on a small slab on the ground alongside many homes or on the roof of large buildings, air conditioning units contain the compressor and condensing coils that enable the main (and noisiest) function of the process.

The refrigerant is contained within a closed loop, entering the compressor as an expanded gas full of heat.  Under pressure, that heat is released when the molecules are squeezed so tightly together the refrigerant returns to its liquid state.

The passing into the condensing coils, a series of delicate fins, the released heat is allowed to dissipate through the fins into the air where a small fan blows it away.  Water is also a by-product of the condensation and drains into a pan and eventually into the ground.

The condensing coil ends at the exchange valve where it is held to create just the right pressure for the evaporating coil indoors to operate at its maximum efficiency.

Refreshing Maintenance

If air conditioning maintenance is performed regularly, the system requires little attention and over sight beyond scheduled appointments with a company like Cool Touch Air Conditioning & Heating Specialists.  Even in the most brutal of climates, relaxed and comfortable in our spaces, we are able to do our stuff and sleep well at night.

Spring Cleaning and Your HVAC System in Buckeye

Monday, May 14th, 2012

If you are working on cleaning your home for spring, don’t forget your heating and air conditioning system in Buckeye. If you are turning your furnace off, you should change the air filter so it is ready to go next heating season. It is also important to check your air conditioner’s filter, which needs to be clean to ensure efficient operation. A dirty AC filter can reduce air flow, which can not only waste energy but possibly cause ice to build up on your coils.

While you are checking over your AC equipment, it’s a good idea to schedule an annual air conditioning maintenance visit with your HVAC contractor. One of the many things they will do is clean your AC, including the evaporator and condenser coils, which will help your unit maintain its energy efficiency. Since you are cleaning the rest of your home anyway, it’s a good idea to get your air conditioner in peak shape at the same time. If you don’t know how to change your AC’s air filter, ask your maintenance technician to show you. You should also determine how often you should change your air filter, which can depend on the amount of dust in your home, the number of pets you have, and the type of air filter you use.

Other important spring cleaning tasks include changing the filter in your vacuum, which can help maintain indoor air quality, and changing your water filter. Whether you have a whole house water filter or a Brita pitcher, the filters need to be replaced on a regular basis to keep them working effectively. If you have an air cleaning system, it’s probably a good idea to replace those filters as well, and check to make sure you don’t need UV germicidal light bulb replacement. While each of these steps seems simple, it they can add up to a healthier, more efficient house.

Indoor Air Conditioning Components for Peoria Homes

Monday, April 16th, 2012

Air conditioning in Peoria is a modern convenience that we can easily take for granted as long as all the parts are working well.  In every unit, no matter the size, the basic process is one of extracting heat from the conditioned space and moving it to the outside, leaving cool air in its place.

This process easily divides into indoor and outdoor components.

Air Conditioning 101

Based on the principal of thermal energy which states that heat gravitates toward cooler temperatures, compounds known as refrigerants are moved through a closed loop system, repeatedly contracting and expanding between liquid and gas forms, alternately releasing and absorbing heat along the way.  The particular chemicals are selected for their abilities to transform from one state to the other at low temperatures.

While the refrigerant evaporates into a gaseous state within the looped system, it absorbs heat, removing the stale air from the space being conditioned and evacuating it to the outdoors. The warm air is pulled through ducts to meet with the cooling loop.

Ductwork

The cooled air is distributed through ducts or tubing and released into individual spaces.  Additional ductwork is required to remove the stale air and pull it back to be reconditioned as it passes over the loop containing the refrigerant.  The air is moved in both directions by a blower, usually electric and sized to handle the amount of air no matter the building.

Ductwork is also sized to handle appropriate volumes of air. To maintain efficiency, large trunks distribute along central lines to smaller ones reaching farther out. The return air is usually taken from common areas.

The grates are found in the walls, floors and often as part of the dropped ceiling. When combined with a forced air heating system, the total energy use is much more efficient.

Looped Coils

The refrigerant is enclosed in a loop where it can expand and contract to make its transformation from gas to liquid and back again.  To change into a heat-absorbing gas, it travels through the evaporating coils, an intricate series of delicate fins that meets with the ductwork to regenerate the conditioned air.

An exchange valve allows just the right amount of liquid refrigerant into the evaporator coils.  If there is too much, the tube is flooded too tightly to allow expansion of the molecules and room to attract the heat.  If too little, the process is inefficient.

Cool Maintenance

If an air conditioning maintenance is performed on a regular basis, the system functions with little attention and over sight.  Relaxed and comfortable, even on the most brutal of days, we are able to do our stuff and sleep well.  Contact Cool Touch Air Conditioning & Heating Specialists
