How Humidity Affects an Air Conditioning System

An air conditioner is an essential requirement in most homes. It helps to reduce the temperatures. During summer, high humidity causes an excessive increase in temperatures. Your home will be extra warm which can be uncomfortable. Air conditioners help reach a favorable temperature by removing heat and moisture from the air through condensation. Lack of sufficient cooling capacity of the air conditioner might lead to a malfunction.

On the other hand, low humidity levels can cause a decline in temperatures below the standard degrees during the winter. When the humidity levels fall below 50 percent, the temperatures are below your house natural warmth. The heat pump will work at a higher rate to restore the warm temperatures in your home.
Solutions:

Now that it has been established that low and high humidity levels have a negative impact on your air conditioning system, how do you prevent it from happening?

Invest in a dehumidifier

Combining your Ac with a dehumidifier will enable you to adjust the humidity and temperature levels to your preferred state. The warm, humid air is passed through a cold metal within the dehumidifier leading to condensation. The condensation drops are released from your home through the pipe, and less humid and warm air is discharged to your home to restore the standard temperatures.

Get a humidifier

This device is helpful during winter when the humidity is too low causing low temperatures beyond the standard level in your home. Similar to the dehumidifier, a humidifier is installed in your Ac system. It adds moisture to air which is then released via your air conditioner. This feature helps to keep the humidity above 50 percent level thus restoring warm temperatures in your home.

Size and effectiveness of the AC system

There is a misconception that the bigger the AC system, the more effective is its functioning. It is it is essential to get the right size of unit that is capacity equivalent to your home area. You will end up paying a high price if you purchase a large system for a small space. A mismatch between capacity and size of a system may lead to performance ineffectiveness.

Invest in a professional

Most people prefer installing the system rather than paying a small fee to have it done well by a professional air conditioning company. Investing in the right company means, you will get the right system and proper setting of humidity levels for your home.

What Are The Symptoms Of A Bad AC Compressor?

A bad AC compressor can turn a nice day into an overheated nightmare. Your compressor is one of the most important parts of your cooling system and a common point of failure when things go wrong. Below are just a few symptoms that could indicate that your system is failing.

Signs of a Failing Compressor

In most cases, the first sign that you’ve got a bad compressor will be the fact that your system is blowing warm air. There are other causes, of course, but systems that are on the verge of compressor failure often start to blow warm air instead of cooling down your home. If you notice a sudden change from cold air to warm, there’s a very good chance that you’ll be dealing with a failed compressor in the near future.

You might also notice some power consumption problems if your compressor is in bad shape. If your circuit breaker is frequently tripped when your air conditioning unit is turned on, there’s a very good chance that your compressor is overheating and drawing in too much power. It’s very important that you don’t keep resetting your circuit breaker in this case – if your compressor stays in the state, you might be looking at a catastrophic failure.

Other signs are a little more dramatic. If you notice that your condensing unit is violently shaking every time that you turn on your air conditioning, there’s a chance that your compressor is having trouble turning on. Likewise, a nosy condensing unit can often be a sign that a compressor is starting to struggle. If you’re dealing with either of those signs, there’s a good chance that you’ll need someone to look at your air conditioning unit quickly.

The most dramatic sign of compressor failure, though, is that the compressor stops working altogether. There’s not a problem with the power supply and your indoor fan will keep blowing, but the compressor simply isn’t making any noise at all. If attempts to lower the thermostat aren’t met with any success, you’re probably looking at a compressor that has already failed.

If you think that your compressor isn’t in good shape, it’s better to call for AC repair sooner rather than later. As you can see from the information above, some of the problems that indicate a bad compressor can actually be quite dangerous. If you want to make sure you have a cool home and a working AC compressor, don’t delay – call O.C. McDonald at 408-295-2182 to get the help you need today.

How to Check the License of Contractors in California

Anytime you are considering having work done at your home or office, it’s important to make sure the contractor you choose is fully licensed. It’s easy to assume a contractor would not operate without a valid license; however, you might be surprised at how often contractors continue to work without the proper licensing. Fortunately, checking for a license is incredibly simple, and it can be done with just a few pieces of information.
To check for a current contractor’s license in California, simply visit the Contractors State License Board (CSLB) website. Once there, you’ll need to enter the business name, individual’s name, or license number to be shown a list of companies matching the information given. For each company listed, it will also show the contractor’s name, license number, city of business, and current status of their license.
Once you have found the contractor you’re looking for, click on the license number listed. This will give you further information on the contractor such as:

  • Business address
  • Entity type
  • Date of license issue and expiration
  • Bonding information
  • Details on their insurance

Why Checking a Contractor’s License is Important

While this may seem like a lot of effort, hiring a contractor who does not have an active license can cause serious problems for you down the road. If your contractor is unlicensed, you could personally be stuck with any repair costs due to issues with the work. It’s also in your best interest to verify that the contractor is both bonded and properly insured. Being bonded basically ensures the contractor’s customers are covered financially if the contractor’s work causes damage or is otherwise done improperly. Verifying that the contractor carries insurance that is adequate for covering your project is also a smart move. Of course, a reliable contractor will have all of this information handy for customers from the start, but it never hurts to verify since this can impact you greatly if they falsify any of the information.

Selecting the right contractor for your job can seem stressful, but it is worth researching to ensure everything is done properly. For a business you know you can trust, O.C. McDonald is here to help! Give us a call today at 408-295-2182 to get started on your next project.

The Advantages of Fabricating New Sheet Metal for Your HVAC System

Another few years have passed and now it’s time for you to perform maintenance on your HVAC system. It takes time and money, and then you have to do it all again in the next few years. You should instead consider replacing the material in your HVAC system with sheet metal. Though thin, sheet metal has proven to be strong, efficient, and cost-effective. Whether you are a facilitation manager for a large company or responsible for new construction projects, sheet metal is highly recommended for ventilation ducts.

Sheet metal can withstand large amounts of pressure along with the harsh weathers ranging from frigid to scorching. It is lighter than other material used for ventilation ducts. Regardless, it’s the custom fabrication of the sheet metal that is specifically tailored for your business. Sheet metal is cost- and time-effective because it’s simpler to make. The material isn’t imported from across the sea. Not only does it save money for HVAC contractors, but it saves on your company’s energy bills in the long run.

The Efficiency of Sheet Metal for Your HVAC System

There are a number of ways that sheet metal is economical for your company:

  • custom fabrication reduces air leaks
  • the relatively smaller size allows for better air volume and distribution
  • easier to manage

Sheet metal is always custom fabricated, and this is beneficial. Regular, generic-shaped air ducts are not as stable; they have a tendency to move and bend while in use. This causes air leaks. Air leaks mean that your ventilation would have to work even harder to get the air to its destination. It will stay on longer and increase your energy bill. Custom fabricated sheet metal is sealed tightly and cut to fit your building. It will not experience energy losses like normal air ducts.

Due to its smaller size and sealed design, sheet metal ducts allows air to flow through in smaller volumes. Therefore, the fresh air will make it to the designated rooms faster. These ducts simply have better control of the air volume. As a result, this is another way your HVAC systems won’t have to work as hard and saves your company money on the energy bill.

Maintenence should still be required every few years for your HVAC systems. However, sheet metal makes it easier for HVAC technicians to service. You also will not be required to have to replace it every few years. This is because custom fabricated sheet metal ducts are more durable, and is yet another money-saver.

If you’re ready to save money on your energy bill, then call us today at 408-295-2182 and inquire about sheet metal ducts for your building.

3 Things To Look For To Find The Best Contractor in San Jose

Finding a reputable plumbing, process piping and HVAC contractor requires more than comparing bottom line prices and being moved by creative marketing. Here are three areas you should look closely at when evaluating a contractor for your upcoming construction project.

Quality of the Contractor’s Bid

Evaluate these four areas to determine the level of quality you can expect.

Cost
Fully evaluate the financial-cost, time-cost and quality-cost of the bid. Ask yourself if a low-price bidder will be able to meet your project timeline. Consider the price and quality connection or workmanship and materials over time.

Scope
Make sure the contractor understands the scope of your project. They should ask questions to gain a sense of what you need and be able to offer alternatives, rather than pricing your project as if it were a product.

Warranty
Look for a contractor who can provide a sufficient warranty and can guarantee quality workmanship. You should see evidence of an efficient workflow process and sourcing of quality materials for your project.

Interview
Meet with, speak to, or collaborate with the contractor before or during the bidding process to get a sense of how they will work with you during the construction phase of your project.

License, insurance and bonding

You should not need to do much legwork in this area. A reputable contractor should include their license number and classification with every bid and display it on their website. Ask about their insurance liability limits and make sure that they are bonded to meet the financial obligations of your project.

Contractor’s Background and Credentials

Determine if the contractor is the right fit for your project.

Experience
Check if the company has worked mainly as a subcontractor of if they have experience as a general contractor. Also look for areas of specialization that match your project requirements.

Portfolio
Ask for a list of projects they have worked on that are like yours.

References
Get a list of clients who will speak to you about their experience, rather than relying on quoted testimonials.

Commitment to Your Construction Project

Ask if you will have a dedicated project manager. Inquire about how the contractor’s other projects will affect their ability to meet your timelines. Finally, make sure the contractor has the flexibility to work with your staff and adapt to any changes in the project.
