Tips For Keeping Your HVAC Happy And Your Home Cool

With summer almost here, it is critical to keep your house relaxing and cool from the start of the season until the end of the humid and hot weather. The best option for achieving this is an HVAC system. Most people have this type of system installed in their homes already. A well maintained and dependable system will help to save you from the summer heat and the winter cold as well. However, to keep it operating smoothly during the summer and to avoid sweaty unpleasant days due to maintenance and service problems, follow these tips in order to keep your HVAC happy and your home cool all summer long.

1. Clean the air filters on a regular basis.

Cleaning the air filters helps to improve the HVAC heating and cooling performance. All of the foul air and humidity is thrown out by the vent system into the room and along with that dust is absorbed but there are air filters that block them getting inside of the system, while dust particles begin to accumulate on the filters’ surfaces. If you don’t clean the filters in a timely manner, then the blockage may make it difficult for cooling air to come through the vents.

The clogged filters also make your HVAC system have to work longer and hard and places a big load onto your cooling system in order to regular the room’s temperature. This result in heavy amounts of electricity being consumer and the life span of your HVAC system being reduced. Therefore, cleaning your outdoor and indoor filters and help to keep your home cool.

2. Check the system ahead of time

People have a tendency to put of having their HVAC system’s capabilities checked until summer has arrived. Frequently when you need to have your cooling system work properly during the summer, the cooling system ends up not working correctly. This situation is totally avoidable and the trick is to make sure that your HVAC system is checked before summer hits in order to avoid any unnecessary problems.

3. Schedule regular maintenance

It can be expensive to maintain an HVAC system, but replacing and repairing an entire HVAC system is a lot more expensive. It is essential to have a professional and trustworthy HVAC service provider to keep your HVAC system and home happy. It is essential to have your cooling system thoroughly examined two times per year. Scheduling two HVAC service visits at least every year can save you a lot on your repair costs and will increase your HVAC system’s performance and life.

4. Pay attention to warning signs

Whenever strange noises start coming out of the air conditioner or your thermostat starts malfunctioning, those are signs that there is some problem occurring in your cooling system’s functionality. Make sure you check into the problem. Your filter may need to be changed or ice may be built up inside of your system. However, if you are unable to find any problems on your own, give your local AC service provider a call as soon as you can before the problem grows worse and causes damage to your HVAC system.

5. Take good of your outdoor compressor

A cooling system’s outdoor compressor is as important as your indoor system is. All of the heat from the system and room is evacuated out by the outdoor compressor. It is very important that the system not be obstructed. Look out for any grown plants or shrubs around the compressor. If you make sure that the outdoor unit stays clear it will help to ensure that your cooling system works efficiently.

6. Seal the leakage

If your home isn’t cooling properly no matter what temperature your thermostat is set at, then you need to look for leaks inside of your HVAC system ducts. When the system is leaking cool air it is a major malfunction that can cost you a lot in terms of energy consumption. Check for leaks in the ducts and then seal them. That will improve the cooling inside of your home.

7. Place furniture away from your vents

Since cool air flows through the indoor vents and into your home, it is critical that your furniture, and other household items, be placed away from the vents. The area directly in front of your cooling vent will need to be clear so that the cooling area can spread properly throughout your home. This is an efficient way of spending less money on your electricity consumption.

The tips above can help to keep you HVAC happy and your home cool all summer long. By following these easy tips, you can ensure that your HVAC system is long lasting and cost-effective for a sweat free and happy summer.

Water Cutting Through Steel?

A waterjet is a metal cutting tool that uses a high-pressure stream of water. It may sound crazy, but an extremely powerful water jet has enough force to cut through metal.

You should imagine a waterjet as a device that spits out water at about 30 times the pressure of the pressure washer used at your local car wash. If you’ve ever used these services, you probably know that power washing can effectively remove dirt and grim from the surface of your car, as well as from its wheel rims and tires.

If you want water to cut through metal, you need to secure the coherence of the spray. Waterjets have the ability to cut because they channel the spray through an extremely narrow nozzle at unbelievably high pressure. This is how they manage to keep the spray coherent.

The biggest advantages of a water cutter over metal cutters is that it never gets dull and it doesn’t overheat in the cutting process.

The first low pressure waterjets were used in the gold mines in California, back in 1852. In the early 1900s, people discovered steam and hot waterjets and used them for cleaning purposes. During the 1960s, high pressure waterjets were used in the mining industry, but it’s only 10 years ago that waterjets started to be used for cutting purposes. Abrasive water jets were already known and used in industry around 1980.

In the past, it was only possible to cut one piece of metal at once, either with a saw or by using some other metal cutting equipment. These processes were laborious and extremely expensive. Today, computer-controlled waterjet and abrasivejet devices are used in most industries to cut a wide array of soft and hard materials. The water-based abrasive mixture passes through the nozzle at an impressive speed of almost 1,000 mph. The most advanced equipment can cut at jet speeds in the Mach 3 range.

Materials that can be cut with waterjets:

  • Marble, granite and other types of stone
  • Various types of metals, including stainless steel
  • Plastic
  • Wood

A water jet is able to cut a stack of different materials with a total thickness of up to four inches, or you could use any steel cutting band saw machinery. This dust-free, odorless and almost heat-free process can be used to cut a sheet of material as thin as a small fraction of an inch. In this situation, one single cut is everything that’s needed for obtaining the final finished surface. This process can save both material and machining costs.

Waterjets are suitable for cutting materials with lower hardness, while abrasive jets are more appropriate for materials with higher hardness values. Sometimes, the cutting occurs under water, in order to minimize splash and noise. Faster feed rates are effective in preventing the jet from, cutting all the way through.

The pressure of the water is usually between 20,000 and 55,000 PSI. The jet has to pass through a 0.010″ to 0.015″ in diameter hole in a jewel nozzle.

When adding SUPER-WATER (a soluble polymeric chemical developed by Berkeley Chemical Research), a waterjet can be used to remove the bark from trees. This can be an extremely effective solution to cut down roadside weeds.
