Why You Should Replace AC Ducts

When you are outside, you can breathe fresh air from all directions. In a building, you might receive the majority of your air from your air conditioning (AC) ducts. Learn why you should replace AC ducts.

Most air is a combination of many different elements, including oxygen. The dirtiest air is filled with germs, dust, smoke and other airborne contaminants. Some diseases are spread through the air.

When your workers have the freshest air with the highest percentages of oxygen, they are the most productive. They can concentrate and complete tasks faster. Here are some of the reasons for replacing AC duct work:

  • Fresh Air
  • Reduce Airborne Contaminants
  • Prevent Diseases
  • Indoor Air Quality

Do you know what is breeding in your air duct work?

Replace Air Ducts

When an athlete goes to the sideline, he gets oxygen to reinvigorate him. Fresh air can increase your workers’ productivity. They can process information faster and complete their tasks on time.

Do you want your workers to be coughing into their keyboards? This prevents them from completing their assignments. It also spreads germs and increases the chances that others will get sick too.

More sick time will lead to fewer productive hours. Airborne diseases can cause simple fatigue or lead to more serious lung problems. This is especially true during the flu season.

There are many other types of contaminants that simply make breathing more difficult. Dust can clog up the lungs. Coal mine workers eventually get “black lung” due to long periods of exposure to airborne contaminants. How do the lungs of your employees look?

As a building owner, you are not only responsible for your employees, but also guests and vendors. What do they say about your Indoor Air Quality behind your back? Do they rue visiting your establishment or leave with a hacking cough?

If you care about promoting an image of excellence, does this not extend to having superior Indoor Air Quality also? Rats, squirrels, bats and birds nest inside your air ducts. Vermin leave all sort of waste material that are then recycled into the air, you breathe.

Replacing your AC ducts can help all people breathe easier, avoid airborne diseases and work more productively. Are you convinced that your AC ducts need cleaning? If so, call us today at 408-295-2182

Can You Just Replace an AC Compressor Instead of The Whole Thing?

The HVAC system of your business is a critical component of your building and its function is vital to the overall health and ability of your business to function, whether you are running a small office building or a large industrial complex. Keeping the air temperatures regulated and airflow moving steadily can impact your bottom line.

Often, as the HVAC unit or units for your business age, they show symptoms of failure before complete breakdown. Symptoms such as failure to produce cool air can be tracked to a number of smaller issues, such as a coolant leak or a line blockage, but a thorough inspection by an HVAC professional may also uncover major issues such as a compressor failure.

In the case of a compressor failure, you need to decide whether your business will best be served by replacing the compressor or by replacing the entire AC unit.

Replace the Compressor or Replace the AC Unit?

  • Consider replacing just the compressor if the existing AC unit and component parts are still under warranty. In this instance, the new compressor should not cost you anything but you will still need to pay for the labor to do the job. Make sure to get a quote on the labor, time, and materials as replacing a compressor can be a challenging and time-intensive job.
  • Consider replacing the AC unit if the system is past warranty. While you could opt for replacing just the compressor in this case, bear in mind that the cost of a new compressor, as well as the cost for labor and materials, may be close in range to the cost of installing a new AC unit.
  • Consider as well that a new compressor may only come with a limited warranty, up to
    1-2 years, and that you may find yourself back in the same situation in a short amount of time, facing the same issue without the benefit and security of a warranty to offset the cost.

Dealing with the advanced and technical needs of your HVAC system can be daunting, especially if your business is impacted by changes in temperature and loss of cooling due to AC problems. Let us solve your AC problems so you can focus on what matters most: the success of your business. We can help, call now 408-295-2182

Can anyone change a thermostat?

As with many home repairs, changing a thermostat might seem like it requires a specialist. Whether adjusting your current aging thermostat has become a guessing game or you have a new smart thermostat, rest assured changing it is an easy process.

Let’s walk through the steps.

First, identify the type of heating and cooling controlled by the thermostat. Some people have unique systems which require a certain replacement. Examples include having separate heating and AC units, having designated high and low speeds, or having a direct current power source powering the thermostat.

To begin, turn off the power to your air conditioning and furnace units controlled by the thermostat. Do this by flipping the correct switch in your breaker box or by individually turning each of the units off at their source.

Check and make sure they are off by adjusting the temperature to a high or low temperature to see if anything turns on. From there, remove the face of the thermostat.

Make note of which wires will go where on your new thermostat. To accomplish this:

  • Draw the wire locations
  • Take a picture
  • Refer to the old or new thermostat manual

Next, begin disconnecting the wires. Depending on the design of the thermostat, this may require a tool, likely a screwdriver. With the wires disconnected, remove the mount of the old thermostat, which will also likely require a screwdriver.

Out with the old, in with the new (thermostat)

With the old thermostat out of the way, it’s time to put on the new mount. To save yourself time and trouble, make sure that you will be able to screw the new mount to the wall. This likely requires two drywall anchors being in the correct location. If it looks like it works, slide the wires through the hole in the mount.

Connect the wires to the new mount. Refer to the method you used from earlier for this, otherwise the letters on the mount correspond to the color of the wire. Newer thermostats no longer use screws, so refer the manual to confirm the wires are securely in place. Once wired, screw the mount to the wall.

Now attach your new thermostat face and turn the power back on. Depending on your thermostat, you can now configure it and adjust the settings to your preference.

What Is Included In An HVAC Tuneup?

Are you wondering why your company is spending more money on electricity?

When you first install your heating and AC units, you will notice that your electric costs are fairly low. Modern technology has made our heating and cooling systems much more efficient than in past years. However, heating and cooling units degrade over time. Much like your car, heating and AC units are mechanical and need to be serviced in order to reach their full potential.

This is when an HVAC tune-up is needed.

What Happens During An HVAC Tune-Up?

An HVAC tune-up is an annual inspection and repair of your heating and ac units. A tune-up will keep your systems running at peak efficiency so that they will last longer and cost less money to use.

When the service professional arrives at your business, he will spend anywhere from one to two hours inspecting and performing maintenance on your units.

He will identify what parts of your units are not working at their peak efficiency.

What Happens During An AC Unit Tune-Up?

When tuning up your AC unit, the service professional will:

  • Adjust your thermostat
  • Clean your air filter
  • Repair exposed wires
  • Ensure that your fan is blowing
  • Measure the amperage of the compressor

There are many other smaller tasks that your professional will do such as inspecting your indoor coil and testing your capacitors.

If your AC unit frequently freezes, the inspector will look for blocked airflow, refrigerant leaks, and issues with internal coils. A frozen AC unit can be unpleasant during the warmer months. Frequent tune-ups can prevent the situation from happening.

What Happens During A Heating Unit Tune-Up?

When tuning up your heating unit, the service professional will:

  • Inspect the internal heating elements
  • Check the burners for proper ignition
  • Adjust the flame sensor
  • Test the carbon monoxide detector

During the inspection, the exterior will be analyzed for leaks, corrosion, and proper ventilation. This inspection and tune-up can help your heating unit last for many years and run at peak efficiency.

Getting Your HVAC Units Ready For The Winter Months in Silicon Valley

The central heating, ventilation, and air-conditioning (HVAC) system that serves your facility is important to your operations in the summer months, but it can take on even more significance in the winter if your facility includes data-center infrastructure. This is because, during colder weather, both your indoor heating and cooling systems must work in concert to keep your equipment at the proper operating temperatures.

If you take proactive steps to prepare your main and server-room cooling equipment for impending cold weather, you can prevent weather-related damage, repair existing issues, and optimize the performance of your climate-control systems. Some critical elements of the main-facility HVAC winterization process include:

  • Energy Audits: This process involves an overall check of the energy-efficiency of your facility. By weighing your existing energy usage against established baselines, our auditors can detect inefficiencies and suggest ways of improving energy-usage.
  • Infrastructure Inspections: Your HVAC system likely includes a network of pipes, coils, ducts, fittings, and more. These vital components require regular maintenance checks, and especially so before major seasonal weather changes. Some common service items include refrigerant tests, pressure and leaks tests, and thermostat calibrations.
  • Temperature Zone Consistency Check: If your facility is large, it likely includes several temperature and environmental zones within its structure. Keeping the temperatures in each zone at the proper levels requires regular maintenance of related environmental control hardware and software.

Server-Room Cooling Systems

The soundness of your server-side cooling systems is just as essential to the health of your enterprise. These systems keep your servers and their surrounding environment within temperature and humidity ranges set by the American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) data-center guidelines. Common cooling system designs include:

  • Liquid Cooled Systems: These cooling designs use liquid-antifreeze to capture and remove server-generated heat. Checks of these components may involve antifreeze fluid level and chemical composition tests. In addition, structural integrity checks are often performed on piping.
  • Air-Cooled Systems: Air-cooled designs use chilled air to cool hot server racks and rooms. Maintenance checks for these types of systems often include duct, inlet, and outlet inspections. Technicians often use this opportunity to sample and adjust humidity levels.

Keeping your data-center cooling apparatus in good operating condition is key to the success of your enterprise. At our firm, we field teams of certified and experienced HVAC system maintenance specialists with experience in inspecting, repairing, maintaining, and installing a variety of server-room and facility cooling systems. To begin your HVAC system winterization process, contact us now for a conversation about the unique needs of your facility.  Call (408) 295-2182

How Much is Air Conditioner Repair?

Air conditioner repair costs will vary depending on the brand, size, and type of air conditioner. However, it is important to have an experienced HVAC technician come and evaluate your system before deciding whether or not to replace or repair your air conditioner.

So, what’s the problem? Is your air conditioner running but not cooling? Is it not cooling as well as it usually does? Is it making strange noises? These are all questions your technician will want the answers to.

 

Possible Problems With Your Air Conditioner

  • Not feeling as cool as usual. Check the filter and clean it if necessary. Also check around the unit and make sure there is nothing impeding airflow, like plants or curtains. If everything seems clear and you call for a repair, it could cost, according to Home Advisor, as little $200 and as much as $1600 to fix a refrigerant leak and around $200 to recharge the freon.
  • Not turning on, or staying on. If your air conditioner is not turning on or not staying on once it’s turned on, you may have an electrical issue, but you should have a professional check out the condenser, the evaporator unit, and the fan. They may just need to be cleaned, but could need repair. Condenser fan replacement can cost around $500 and an evaporator unit may cost as much as $1000. A circuit board, relays, or other electrical parts could cost as little as $15 or as much as $300.
  • Rattling or other noises coming from the unit? Call a pro and get a tune-up. You might need a few pieces lubed or other parts cleaned and looked at. This will cost in $75 to $150 range according to Home Advisor.
  • Use the 5,000 rule. Many HVAC technicians suggest using the 5,000 rule. Essentially, this means you take the age of the unit and multiply it by the cost of the repair. If the answer is more than $5,000, you should probably replace the unit. For example, if you’re air conditioner is 10 years old and the repair will be $250, you should repair that unit as the answer is only $2,500.

No matter what the problem, make sure you consult with your HVAC technician to make sure you are taking care of the unit properly. If the unit is aging and a repair might be costly, replacing might be your best option. Need help with your repair? Give us a call at (408) 295-2182
