What’s The Difference Between Residential Air Conditioning Companies And Commercial Ones?

There are essentially two types of HVAC companies, residential and commercial and many times a combination of the two. The chief difference between the two is one is only licensed to do residential and commercial companies are sometimes licensed to do both. However, most commercial HVAC companies concentrate on commercial projects and leave the residential to others. Some companies however are very good at doing both! These companies have stood the test of time and have endured both good times and bad to get to where they are today.

The chief differences between the two . . .

  • Residential Characteristics – specializing in home air conditioning and heating; Usually can respond after hours or in emergency situations; performs annual start-up and preventive maintenance, repair and installation of residential HVAC equipment; technicians are usually licensed by the state they work in to do only residential work, but not always. There are some residential HVAC companies that are fly-by-night and should be avoided; Reputable companies are licensed, bonded and insured so be sure to review these to ensure they are all current. Usually a permit is required for new installations. The residential HVAC company should be very familiar with the permitting process.
  • Commercial Characteristics – specializing in commercial HVAC applications such as HVAC for retail buildings, office buildings and other non-residential applications; technicians are usually of the Journeymen experience level and are licensed by the state they work in; Commercial HVAC companies are required to be licensed, bonded and insured. Commercial work is generally done under the existing building permit as “maintenance” however most new installations or system renovations are required to be permitted and inspected.

Talking directly about the combination companies referred to earlier, generally these companies have been around for many years and have proven themselves. These companies have resident experts that have performed the various types of HVAC work for many years in the local area. Most of these experts are owners or at least co-owner of the company. Some companies even have specific departments for residential, commercial and new construction. This keeps the focus of the work where it should be, on the customer’s needs.

Can Custom Duct Work Be Done To Fit My Building?

The building that your business occupies for years can prove to your customers that you are here to stay. But what happens when you experience growing pains? Many times a building simply no longer provides what you need. So, now you have some decisions to make. In most cases, a new building is out of the question so you must look deeply into what your needs actually are and compare this list to the existing space and what it could provide in a new configuration.

  • Historically, office space is easy to deal with.
  • However, the comfort level, efficiency and safety of the newly configured space all need to be addressed. When a building is initially designed, the systems tend to be somewhat over-engineered allowing for future expansion and unfortunately a bit less efficiency.
  • In the case of the HVAC system, Rooftop units are easily upgraded to proved additional heating and cooling.
  • In the case of larger buildings with mechanical rooms designated for HVAC equipment, the room and equipment can be reconfigured to meet current needs. Air handling units, pumps and other system components could be upgraded, many times using the existing units by simply increasing capacity. A larger fan motor can provide additional air moving capacity. A pump with a larger motor or even just a differently designed impeller can provide additional water for heating and cooling.

Getting the increased air flow to where you need it!

Upgrading the mechanical room or Rooftop units is all well and good but what about the requirements of the newly reconfigured space? You can assume that the existing ductwork will not be sufficient to handle the new air delivery requirements. Most times, these air delivery requirements are dictated by law for various industries. For example, a laboratory has very different requirements from an office space.

Your HVAC system helps keep the air clean and tempered in your work environment. By law, there are different requirements for “number of air changes per minute” in a space. This keeps the air fresher by venting a portion of the air to atmosphere and replacing it with fresh air.

Custom duct work is a large part of the building renovation process. If you find yourself in this situation kindly give us a call and we will help you through the process. Ready to get started? Call us today at 408-295-2182

How To Verify A Legitimate Contractor In California

If you have spent any length of time in California, then chances are you will deal with an HVAC contractor sooner or later. Like everyone else, you are probably very concerned about avoiding getting scammed or ripped off. How do you verify a California contractor? That will be the scope of this article, and there are two good ways and one great way. Consider the following options:

•Word of mouth
•Internet reviews
•Licensure checking

Word of Mouth

Word of mouth would be one okay way to verify a legitimate contractor. However, it definitely has its limitations. Even if you know someone who has used the contractor in the past, the pool of people you can sample from is limited to how many you might know. Frankly, this method would probably only work effectively within a smaller community.

Internet Reviews

Internet reviews are, in some cases, a more effective way to verify a HVAC contractor. However, even and internet reviews, there is the potential for a smaller sample size. There are only a certain number of people that might take the trouble to go onto the website to leave a review. So, even though it might be better then word-of-mouth, the sample size might still be fairly low.

Licensure checks

Calling up the license your agency might be the best way to legitimately verify an HVAC contractor in California. This is because it is one great way to determine if there have been any complaints lodged against the individual, and to note the severity of any complaints that are present. The state license your boards keep meticulous records regarding each and every incident that one of their contractors is involved in. This means that if you call them you can have peace of mind that they do quality work if the licensure board reports no incidents against them.

Other Considerations

Besides the three mentioned above, there are other considerations that could come into play. The length of time the contractor has been in business could play a definite role. In that case, a combination of all three might be the best approach.

Reasons To Go Ahead And Call A Plumber Before Attempting DIY

You are having plumbing issues at one of your in town locations. You have been tossing around the idea of calling a plumber, but you tend to think that you can just do the work yourself. Some problems you have been having are:

  • Gurgling after flushing
  • The Water goes down the drain slowly
  • Dirt comes back up into a shower near the toilet

How difficult could it be to fix these issues yourself? It depends on how deep the problem runs into your building’s plumbing system. Additionally, doing something incorrect could easily lead to a more expensive plumbing repair job than you started out with facing. Do you really want to risk it? The following are a few reasons why you should go ahead and call a plumber instead of trying to do it yourself.

You Do Not Have the Safety Gear You Need

You have what appears to be a clog in one of your pipes, and you are imagining all it needs is a little drain cleaner. Before you start pumping chemicals into the line, did you know that you are supposed to be wearing safety goggles when using these products? Some of these products can even be harmful to certain types of materials that pipes are made out of, but that plumbing mess may not come about as an immediate response to the action you are thinking of taking. Plus, if it does not work, when you do call a plumber you might forget to tell them you put chemicals in the line. Not suspecting that to be the case, the plumber could get sprayed in the face with dangerous chemicals while fixing the problem. This could have all been avoided if you had let the professionals take care of the clog.

Pipes in the Walls and Floors

You have suspected for some time that there is a leak in your building’s pipes. Not sure where it is exactly, you have been imagining that you should go ahead and start breaking one of the walls down with a sledge hammer and chase the leak down yourself. If it is not there, then you might think about tearing into the floor to check those pipes too. The great thing about calling a plumber to help you figure this out is that they can scope the line and find the leak without breaking anything—especially those pipes in the wall you cannot see. If you break one of those pipes, the repair costs will be much greater.

Help Is on the Way

The plumbing inside your business is actually a pretty sophisticated network of pipes and junctions. Tampering with the wrong pipes and fittings could result in you flooding your office building. It is a good bet that is a situation you do not want to have to pay for to remedy. There is a much better solution. To speak with one of our friendly customer service representatives, call 408-295-2182 and let us help you get the job done the right way the first time around.

Who To Call (And Why) For Water Pressure Issues On Your Commercial Property

When you’re the property manager of a single -story or multi-story commercial building in and around San Jose, it’s important to take water pressure problems seriously. Normal water pressure ranges from 40psi to 80psi. If you have a sudden drop in water pressure from the lower to the upper floors, your boost pumps could be broken or you could have numerous leaks in your plumbing system.

Why You Should Call a Plumber for Your Water Pressure Problems

While low water pressure may not seem like a big deal, it can be disastrous for your building, depending on the cause. Common causes of low water pressure include:

  • Boost pump failures
  • Incorrect pressure switch setting
  • Malfunctioning or old water fixtures
  • Numerous small water leaks
  • Pipe corrosion
  • Pressure regulator failure
  • Problems with water valves
  • Problems with the city water supply

While it is possible that your water pressure problems are due to low pressure within the city’s water supply system, it is unlikely.

Tips On Preparing Your HVAC Unit For Spring – Before You Call A Contractor

After a long, cold winter, spring is finally here, and soon it will be time to crank up the AC to keep your home comfortable during the dog days of summer. Before the time comes to cool your home, it’s important to do some routine checks and make sure your HVAC unit is up for the challenge of the next season. A few tips and tricks can help you ensure you won’t suffer an untimely AC breakdown, or break the bank because of poor efficiency, which can add up quickly on your energy bill.

4 Tips to Get Your AC/HVAC Ready for Spring

Change old filters

Replacing old, dirty filters of the easiest methods of making sure your HVAC unit is ready for the spring and summer months. Even when not in use, dust can collect in these filters, which can lead to unpleasant odors, low airflow, and increased electricity usage. Because your AC has to work harder and run longer to push enough air to cool your home, it can also put undue stress on other parts, causing them to wear out more quickly. Before you replace filters, be sure to know the correct type and size for your unit.

Turn it on and let it run

Once the filters are taken care of, the next step is to turn on the unit and let it run a while. Don’t leave the house during this process; stay close and observe for any odd sounds or scents. Take particular note if anything smells like it may be burning, and turn off the unit immediately.

Take a quick peek inside

Many homeowners neglect the simple but important step of checking the condenser coil for any signs of damage or debris. You’ll also want to look at your system’s wiring to ensure nothing seems disconnected or is showing signs of wear and tear.

Get a tune-up

The best way to make certain your AC is ready for spring is to call a professional and schedule a check-over. A full inspection, including a thermostat test, condenser inspection, checking contractors for any pits or burns, and other general maintenance will help save on large repairs or increasing energy bills. When you’re ready for your next HVAC tune-up, repair, or if you have any questions about your AC unit, contact us at (408) 295-2182

Tips For Environmental Heating and Cooling in San Jose

Environmental heating and cooling is an objective for companies aiming to be better corporate citizens. Investing in heating and cooling systems can help a company reduce its carbon footprint and save money. Here are some tips for environmental heating and cooling in San Jose.

 

Implementing zoning

One of the most common recommendations we offer to our customers is to implement zoning. HVAC systems with zoning configurations only cool and heat the areas of the building that are currently in use. Less energy is consumed when the system is not being operated. Rooms that are positioned near sunlight can be assigned a zone to be inactive during daylight hours when the temperature are higher, avoiding the use of heat. Likewise, the cooling settings can be adjusted to higher temperatures where people are in constant motion and more likely to be warmer.

 

Setting up a maintenance plan

Implementing a maintenance plan is another way to save energy. Changing the HVAC filters periodically can reduce wasted energy consumption by anywhere between 5 and 10 percent. Clogged filters impact indoor quality. The restricted air flow also causes the HVAC systems to operate inefficiently. It is recommended that the HVAC filters be changed on a quarterly basis to preserve the performance of the HVAC system. Some experts suggest that they be replaced every three months to achieve true energy savings.

 

Know when it’s time for an upgrade

Sometimes systems can only do but so much when they reach a certain point in their service life. If you find that the repairs are becoming more frequent, then your system may need to be replaced. Upgrading your HVAC system will reduce your energy consumption and lower energy costs. The more energy efficient tend to be the newer systems released in recent years.

 

Consider retrofitting

Retrofitting your HVAC unit is another option. Advanced control systems and sensors can be added to the existing system. This means that the area is only cooled or heated when ventilation is needed. The sensors gauge fluctuations and temperatures, trigger heating or cooling activities as needed.

If you are ready to reduce energy consumption and are open to exploring the options available, consider implementing any of these solutions. If you have any questions about improving the energy efficiency of your system, call us today at 408-295-2182

Choosing The Right Company To Perform Your HVAC Tuneup

Choosing the right company to provide your HVAC tuneup is crucial. A regular heat and air tuneup is vital when it comes to keeping equipment performing properly and in top condition. In addition to obtaining important maintenance during the tuneup process, a professional has the opportunity to identify and resolve any minor issues. Proactive intervention in regard to something more minor today is a key strategy to preventing a major problem at some juncture down the road. In other words, regular maintenance can enhance the lifespan of your HVAC system.

Another fundamental reason why you need to select the proper company to perform your maintenance stems from more long term financial considerations. If you engage a service provider that provides a proper tuneup, you will save money on repairs over the long run. In addition, a well-maintained HVAC system saves money as well.

 

Checklist for Finding the Right HVAC Tuneup Professional

 

There are some specific factors that you need to bear in mind when you are looking for a heating and air conditioning professional. By paying attention to these tips, you’ll be in the best position to access the most capable HVAC professional.

Experience matters when it comes to an HVAC professional. What this means is you need to engage a professional who has a background in performing a tuneup and regular maintenance on a heat and air system like your own.

Finding The Right Plumbers For In Depth Pipe Inspection

There is never a good time to experience a plumbing problem. In fact, most people experience a plumbing problem when they are least expecting it. Due to major strides made in the area of plumbing, an in-depth pipe inspection can be performed to detect and diagnose the source of the plumbing problem. Where plumbers once had to guess and devote a lot time to semi-productive troubleshooting, professional plumbers can now use video inspection to accurately resolve any plumbing problems.

What is an in-depth pipe inspection?

An in-depth pipe inspection involves the use of a camera line being used to video the internal plumbing lines within a home. The line inspection saves the plumber time in its ability to capture key information to make a solid determination about the problem. The line inspection also prevents money from being spent toward unnecessary repairs that will do little to solve the problem. The video is used to inspect the plumbing lines to identify any vulnerabilities with the plumbing.

Why do you need an in-depth pipe inspection?

An in-depth pipe inspection can identify more than just blockages. It can uncover structural issues with the lines. A cracked pipe or a problem with tree root invasion are only visible using a video camera pipe inspection. A pipe inspection can also help determine whether or not another problem affecting the sewer lines is imminent, giving the homeowner the opportunity to be proactive in addressing the matter. The process identifies both the problem and the root cause of the problem. When repairs are suggested by the plumber, the most accurate information is used to make recommendations.

What can be seen?

The video inspection can be revealing, uncovering a multitude of risks with the plumbing. Roots that have penetrated the pipe leading to drainage problems can be detected with video camera inspections. Improperly placed sewer lines are also detected during the process. The quality of the materials used in the piping can also be analyzed to gauge the life expectancy of the plumbing lines. Changes in the positioning of the pipes due to shifting may be the potential root cause for drainage problems, and this could be detected by video inspection. The workmanship of the installers can be evaluated during the inspection process.

A plumber can provide preliminary guidance on steps to take to resolve minor plumbing problems. Identifying the underlying root cause of any issue is something that can be uncovered through the use of in-depth video camera inspections. Inspections can identify the problem, extent of the problem, future risks, and structural issues that contribute to plumbing problems.
