Do you need to service air conditioning units?


Annual maintenance is recommended by the manufacturers, and installers of the systems. The majority of the maintenance time, will be spent on cleaning the unit. Keeping the unit clean will help keep it running more efficiently, and can increase the life of the unit.

The technician will inspect the unit to insure it's still in good condition, and will look for parts that may be near the end of their life. Replacing parts before they fail, can save you the headache of replacing them when they fail (which will surely be on the hottest day of the year). Replacing part before they fail, can also help prevent damage to other parts of the unit.

Depending on which company does the service, they may actually measure the amount of cooling the system is providing. They may also check for refrigerant leaks in the system, but likely only if the refrigerant level is low. If you have any questions or concerns, they'll likely address those at this time.

An air conditioner, often referred to as AC, is among the most essential equipment that we need to make our lives comfortable. They help keep our houses warm when it is hot so that we are comfortable in it. Also, these gadgets decrease humidity levels so that we do not have to feel sticky. But that is not all they do. They purify air by filtering out smoke particles, mites and odors. Owing to the advancement of technology, air conditioning manufacturers today design ACs that not only have faster cooling rates but which also save up to 60% electricity. Today's air conditioners also come with anti-dust filters, built-in stabilizers as well as auto adjust temperature feature so that you can have good night's sleep. But just like other equipment, air conditioners need to be regularly maintained for them to give peak performance.

Why it is important to service your air conditioner?

Winter is fast approaching, bringing with it the cold weather that can wreak havoc on your home’s major systems. Most homeowners in Arizona winterize their homes to protect it from the stresses that cold weather brings, but very few include their air conditioner in their winterizing checklist.

While you tend not to use your air conditioner during the colder months, you still need to make sure it’s ready for the changes in temperature. This way, when things heat up in the spring, you are less likely to run into any issues. Winterizing air conditioning units is one of the most important things that you can do as an Arizona homeowner.

Winterizing is More Important than You Think

Winters in Arizona are typically fairly mild, AC unit winter preparation isn’t high on the list of priorities for most homeowners. However, just because Arizona doesn’t seemingly get that cold, this doesn’t mean that your AC unit won’t be affected by the temperature change. Any drop in...

A variety of heating and cooling methods are available, and they all have their own advantages and disadvantages. Your personal situation will dictate the best system for you.

For example, a packaged heating and air-conditioning unit is typically better for you if you need to conserve as much indoors space as possible. For homes with many rooms, however, split heating and cooling units can be a better choice.

Typically, the most common HVAC systems are central packaged heating and cooling, split ductless heating and cooling, or a heat pump.

You can't charge an air conditioner. If you don't know where it goes how are you going to know how to hook up the tank? Where are you going to buy this freon? What kind of "freon" are you going to put in it? Do you have a charging manifold, piercing valve, refrigerant tank, EPA card, and about $350 to buy the tools and refrigerant you would need just to get started? How much are you going to put in? How do you know it needs any "freon"?

Clean it and you will be fine. Wall units rarely leak. They often are neglected when it comes to cleaning and this...

With a diverse population, tropical climate and urbanization, there is a need of AC in almost every part of Singapore. Offices or residential’s, you will see aircon installed even in the subways as the weather is almost hot and humid throughout.

With a diverse population, tropical climate and urbanization, there is a need of AC in almost every part of Singapore. Offices or residentials, you will see aircon installed even in the subways as the weather is almost hot and humid throughout.

Singapore experiences tropical climate most time of the year. There is a need for AC units inside houses or flats or offices. This also means, to make you stay inside comfortably the aircons should be running for longer periods. Well-ventilated houses can lessen this high usage to some degree. But, for those living in flats in Singpore, an air-conditioner is a must because the heat gets trapped inside due to the concrete.

This particular article tackles Trane air conditioners and specially looks at wall air conditioning. It provides guidelines for how to acquire the right wall air conditioning unit for you. After examining it, you will be able to make a much far more informed, intelligent buying evaluation.

Many businesses with smaller buildings consider wall air conditioning units rather then a window or central cooling unit, mainly because they have no windows or because a central cooling unit is too expensive. These types will cool off an entire room and some of the bigger units might cool more than one room. The problem with cooling more than one room is that there is typically only one vent forcing the cooling breeze into the one room so it might be hard to reach other rooms.

These units for cooling rooms are a better choice when it comes to leaving window space free. This is the major advantage over a window style unit. Another difference is that the vents are located in the...

(this article first appeared in the Austin American Statesman in 1996, but it is still relevant today)

We all know that we can pay our auto mechanics a little now for routine service, or pay them a lot later for a major repair. The same idea holds true for your air conditioner or heat pump. If you don’t service your air conditioner or heat pump regularly, you’ll find yourself uncomfortable and broke.

In this article the term air conditioner will apply to a heat pump or a standard air conditioner. Both benefit equally from annual service tune-ups.

An air conditioner is a very tough piece of equipment. It is engineered to withstand all sorts of abuse and keep on running. This is great in most respects, but it can lead to complacency about maintenance. Like a car, air conditioners need regular tune-ups to run properly.

Without regular maintenance an air conditioner loses about 5% of it’s original efficiency for each year of operation....

It’s scary.

When something technical or mechanical breaks, you’re at the mercy of the expert’s advice to figure out what’s wrong and what you need to do to fix it. Who hasn’t had that feeling with a car mechanic when your car breaks down?

But we’re betting you feel the same way if your air conditioner stopped blowing cold air and a contractor told you that it needs a refrigerant charge.

You wonder, “Do I REALLY need a refrigerant / Freon charge, or am I being ripped off?”
It’s a good question! There’s nothing wrong with a healthy dose of skepticism when your money is on the line.

Here are 2 signs an A/C contractor may be trying to scam you and charge you for refrigerant when you might not really need it.

1) Contractor says you need more refrigerant without checking A/C unit

Imagine this scenario: You’re sick, go to the doctor and tell him your symptoms. The doctor looks you up and down and says, “Aha, all you need is surgery!” No...

Central air conditioners have two separate components: the condenser and the evap orator. The condenser unit is usually located outside the house on a concrete slab. The evaporator coil is mounted in the plenum or main duct junction above the furnace.

Most central air conditioners are connected to a home's forced-air distribution system. Thus, the same motor, blower, and ductwork used for heating are used to distribute cool air from the air conditioning system. When a central air conditioner is operating, hot air inside the house flows to the furnace through the return-air duct. The hot air is moved by the blower across the cooled evaporator coil in the plenum and is then delivered through ducts to cool the house. When the air conditioner works but the house doesn't cool, the problem is probably in the distribution system.

Both the evaporator and the condenser are sealed. Therefore, a professional service person should be called for almost any maintenance other than...

On the interior, warm, humid air from your home’s interior is blown through the evaporator coil. The cold coil absorbs heat from the air, cooling it, before the air is circulated back into your home. The humidity in the air condenses on the cool surface of the evaporator coil as liquid water, dripping into a pan below. From the pan, the water flows into a drain tube which is typically routed into a basement floor drain, utility sink, or outdoors.

Over time, algae and mold can build up and potentially plug the drain, so if the drain is either not flowing or flowing very slowly, it will need to be unplugged. A plugged drain can either cause damage by flooding onto the floor or, if the system is equipped with a drain float, cause the system to stop cooling in order to avoid flooding.

First, find the drain line where it leaves the evaporator coil enclosure. The drain is usually a one-inch PVC pipe (white, grey, or black). Follow it to the end where it drains. Often the...
