Finding an Emergency HVAC Service Company

It is late on a Saturday night, the thermometer outside is hovering at the 80 degree mark and your air conditioning system makes a loud grinding noise. There is no way you are going to make it through the rest of the weekend with no ac as the forecast calls for near record heat and no one in your house can sleep as it is. Your only choice is to find someone that offers emergency HVAC air repair.

However, as you are about to find out, only a select few of the heat and air conditioning companies offer any type of afterhours service. Of these an even smaller number are going to be willing to come out late on a Saturday night and take on what might end up being a major and very time consuming repair. This can make it very difficult for you to find anyone that you can trust to send out an experienced technician.

Rather than take the risk of not being able to find anyone who is willing to offer emergency air repair services, you can use the web to find a company that not only offers 24 / 7 service willing to send out a fully trained and highly skilled technician. This is where the difference lies and where you need to be very careful in your selection of air conditioning repair services.

A top quality air conditioning repair service is one that has a number of highly trained technicians on staff that are always on call. When you call an air repair company afterhours, you need to know that not only are they going to be able to provide you with a skilled and highly trained technician, but that he is going to have the parts needed to make the repair. Far too many shops will send out a tech to look at your problem only for him to tell you that he does not have the required parts to make the repair!

This can end up costing you far more than it should as the company is going to charge you for the original emergency service call and then charge you for yet another service call when they finally have the parts you need. This is not what anyone should expect or can afford when they have to call in an emergency ac repair service. Before you allow a company like this to come to your home, you need to verify that they are going to have the parts you need and that their technician is going to be able to get the job done in one trip.

Take your time when looking for an emergency air conditioning repair service. With a little time and research, you can find a company that is not only available 24 / 7 but provides the most highly skilled and professional technicians in the area. You want an HVAC service that will always show up with a full complement of parts ready to get your air conditioning back up and running in the shortest amount of time possible and at a more than reasonable price.

Chain Saw Bars – How to Tell When Yours Needs to Be Replaced

If you use your chain saw at all, eventually you’ll need to look into replacement chain saw bars.

Extended use, improper bar oil application, and dropping, bending or other damage to the bar can all necessitate bar replacement.

What do you need to know about bars in order to get the right one? And how can you maintain the current bar that you have now? This article will discuss these points.

How Do You Know When You Need to Look at Replacement Chain Saw Bars?

One way to tell if your bar needs replacement is simply to look at it carefully.

Is the bar visibly bent? Does the chain slip out of its track? Are you having issues with bar oil lubricating well? When you look at the track on the bar, does it look worn, with the track edges clearly chipped or otherwise deteriorated?

These are all signs that your bar needs replacement.

Of course, damage to the bar can occur if the saw is dropped. When cutting through large tree trunks or limbs the bar can become stuck in the saw groove, which can cause the bar to warp or bend. Do you notice your saw cutting or pulling to one side? These can all be signs that you need a new chain saw bar.

Bar oil is extremely important for the proper operation and maintenance of the saw, and if the bar oil reservoir is allowed to run dry, you can expect that you will be needing a new bar very soon.

If your chainsaw gets extended use, you will want to examine your bar closely at regular intervals to watch for track wear. Since most people use a saw to cut through wood with downward motion, the bottom of the saw bar takes the most pressure, and thus show wear first.

Things to Know Before Buying Replacement Chain Saw Bars

It would be nice if one-size-fit all, but unfortunately this doesn’t happen with chain saw bars.

There are many makes and models, and unless you’re a professional logger who is well-versed in the many variations of chainsaws and parts, then you’ll want to keep the same original size bar that your saw came with.

However, there are after-market bar companies providing new and improved bars that can replace your current bar. For example, the Cannon Bar Works company of Canada makes replacement bars for a number of saw models, and advertise that their bars are laser cut and milled with a unique flame hardening process to provide longer bar life.

To find a replacement bar, you’ll need to know your saw make and model number. You’ll also need to know the chain pitch and the chain gauge.

Chain pitch establishes the size of the chain. Common pitch sizes include ¼ inch,.325 inch and 3/8 inch. The drive sprocket also has to be the same pitch as the chain.

Chain gauge is basically the thickness of the drive link where it fits into the bar groove or track. Chain gauge and the groove bar gauge have to match. Common gauge sizes can be.050,.063 (measured in fractions of one inch), and so on.

You’ll need to know these numbers before you look at new bars.

Proper Care and Maintenance for Chain Saw Bars

The single most important thing you need to do to maintain your bar is keep the bar oil reservoir full!

Bar oil lubricates the chain while it is moving within the groove. Always use new bar and chain oil. Do not use motor oil or bar oil that has been “recycled.” Impurities and dirt in used oil can cause damage to your chain and saw.

A good rule of thumb is whenever you fill the gas tank on your saw, fill the bar oil as well.

Also, make sure that your new bar, sprocket and chain are properly installed and tightened, since improper installation can increase kickback potential.

What is Kickback and How Can It Be Prevented?

A new chain saw bar can be a big help in preventing kickback accidents.

Kickback is generally when the chain teeth on the tip of the saw bar “grab” the wood and “kick” the bar back toward the operator. This is often a quick and violent action and can be quite dangerous to the operator. (Imagine a saw in full power pivoting off your hands and coming right at you.)

Most chain saws have a tip guard. Some people will remove it, but it is a great safety feature! Maintain a firm grip on the saw at all times, and make sure your saw has the chain brake intact. Avoid sawing with the tip of your saw – use the blade near the motor as much as possible.

Do not saw between your feet when your standing on a log. Maintain your chain, keep it sharp. Chains that are dull are more prone to kickback.

There are even chains that are called “low-kickback,” which are designed for kickback prevention.

Shop online, or your local chain saw dealer can also provide you with suggestions to find the best replacement chain saw bar for your application.
