Should I Repair My AC Unit or Replace It?

Sometimes it is best not to fix your HVAC unit in San Jose and just buy a new one. Deciding this can be a tough decision especially because it can be costly and you do not want to part with something that has been working so good for so long. You consider several factors.

Age

If your AC unit is over ten years old, then you should consider replacing it and not repairing it. Even now companies are recommending that you replace them after seven years. Once you have had your AC for ten years, you have gotten the full life span out of it. They are also now making units that are more energy efficient and run better. You can save up to 30% or 40% by upgrading to a new unit.

Constant Repairs

Constant repairs to your AC unit mean it is time to get a new one. Some repairs are okay to have done, but when it seems like you constantly have to have the handy man out checking out your AC, then there is a problem. You need to consider replacing it if you are spending a lot on the repairs. The money you spend on repairs could be used towards a new unit that will last you. The new units come with warranties and are guaranteed to work. They also now have energy efficient models that will cut back on your bills.

Bills

Lastly, you need to consider replacing your AC unit if you are constantly ringing in each month with high energy bills. When your energy bills start to skyrocket, that means there is a problem with your AC.

You can do away with the problems by deciding to replace your AC unit than keeping it. It can be hard to part with an old AC or even hard to think about buying a new one, but when it comes the time, you must do it. It is better to part with the old one and spend a chunk of money upfront on a new one than hold on to the other washer and spend a bigger chunk of money throughout the year.

Look at these tips and consider them when thinking about your home. You may find out that you need a new AC and never even knew about it. Switching to a new AC will only cause your life to improve.

Ductwork in Commercial Businesses is Often To Blame for Heating and Cooling Problems

Ductwork Problems and HVAC

One of the most interesting things commercial business owners can view is how mechanical engineers design ductwork and how fabricators use those designs to create ductwork for HVAC systems.

The more complex part of ductwork design is how sheet metal fabricators use design instructions and specified materials to create commercial ductwork. Most facility and plant managers take for granted the complexities involved in fabricating ductwork for HVAC systems. Fabricators need to know specific ductwork dimensions, configurations and placement of ductwork in commercial buildings.

Heating and Cooling Problems Relate to Ductwork

Sheet metal fabricators are detail oriented individuals and know matching size, location, fabrication materials and HVAC specifications is crucial to avoiding heating and cooling problems.

Another important feature of ductwork fabrication is proper insulation. Today’s ductwork is comprised of galvanized mild steel and lined with fiberglass duct wrap. In some cases, ductwork may be fabricated from aluminum.

There are several types of ductwork available for HVAC systems. These include:

Sheet metal

Duct board

Flexible

 

How Ductwork Causes Heating and Cooling Problems

Improper ductwork design or materials can cause heating and cooling problems. Ductwork is a system whereby heated or cooled air is passed through to output vents. In HVAC systems there is an input and output vent that allows air to circulate freely from the HVAC operating system through ductwork to vents.

Humidity in areas like San Jose can impact the operating efficiency of ductwork. As humid air passes through ductwork, it tends to cling to duct walls. Tiny microscopic dust particles cling to the moist duct walls and buildup of particulate narrows the free passage of heated or cooled air through the HVAC system.

Reduction in Ductwork Efficiency

Another problem that affects ductwork in commercial businesses is when input and output vents become blocked by boxes, equipment, furniture or dust. This reduces the free flow of air through ducting systems and, by association, reduces air circulation throughout the entire commercial building.

Ductwork Leakage

Another possible cause of heating and cooling failure is leaking ducts. Leaking ducts may be caused by older, existing ductwork that no longer meets the output specifications which results in small leaks in ductwork connections. Look for leaks wherever there is a connection between ductwork sections and connections to the HVAC system.

Expert Ductwork Service

Choose expert sheet metal fabricators for installation of ductwork in your new building. Ductwork fabricators also retro fit ductwork for existing systems for greater efficiency and reliability.

Sheet Metal Fabrication for Ductwork of HVAC Systems in San Jose

When looking at duct-work, one does not think about all the work that goes into building them. Sheet metal fabrication is an art in itself and requires special training to make sure the ducts are solid and will carry the HVAC air through a system with no leaks.

KINDS OF AIR DUCTS

Ducts are used to provide a passage for ventilation, heating and air conditioning. When properly installed they assure quality air is delivered to the interior of any home or building. Having good, solid ducts is essential if a quality air is to be maintained. They must be able to supply air, return it and exhaust it.

Galvanized mild steel is most traditionally used in building ducts. It has a zinc coating which prevents the duct from rusting. Fabricating shop ducts can be made in various shapes to suit special situations.

These ducts are, as a rule, fabricated with duct wrap to make them quieter and eliminate the loss of hot or cold air that would occur without insulation. Some duct-work manufactured today has rigid insulation panels that do not need further lining and can be instantly fashioned and installed. This protection against air loss provides a cost-effective operation with lower utility bills.

Aluminum duct-work is popular because it is lightweight, which makes it easy to install. Sheets of aluminum used are ordinarily pre-insulated panels. After cutting to size, sections of the duct are put together with glue and aluminum tape is applied to the seams.

 

MEETING THE ENERGY STAR® STANDARD

With the high cost of electricity, naturally everyone is looking for a way to cut down their energy costs. Having good insulated duct-work that meets Energy Star® standards is a good step in that direction.

A good sheet metal fabrication shop is well aware of this standard and devotes all efforts to correctly insulate against the possibility of air loss or seam leaks. This assures energy savings as well as cost savings.

A good San Jose sheet metal fabrication shop can design residential or business HVAC custom duct-work that will fit any new or existing heating/cooling system. In addition to the duct-work, they can also custom fabricate things such as duct elbows, offsets, transitions and other parts of the HVAC system.

Mechanical Retrofit, New Installation, Replacements and Repairs for Commercial or Industrial Facility Owners and Managers in Silicon Valley

Regardless of the type of occupant, commercial or industrial facility owners and managers in Silicon Valley can spend a great deal of their maintenance budgets on the HVAC and refrigeration systems in any given year. With the competing demands on scarce resources, business leaders look for the most economical option in deciding what type of action to take when trouble arises. They also may consider the option with the least environmental impact. Companies that specialize in mechanical retrofitting can provide these highly complicated services.

New Installation

Whether installing a new HVAC system or refrigeration system or specific components such as a chiller or cooling tower, property managers and owners rely on mechanical retrofitters to professionally install the components. In some cases of mechanical breakdown, there are few options other than installation of a new HVAC system. In these situations, much of the duct work and power source lines can remain in place. Other parts of the system will be retrofit into the existing building and mechanical system.

Replacement

In other instances, the retrofitter may find that it is only necessary to replace a specific part of the system. Identifying the area of the system that is not functioning properly, replacing a worn or broken part may be a small expense while keeping the majority of existing system. This may extend the life of the mechanical system and lessen the impact that the production of a new system would have on the company’s carbon footprint.

Repairs

Mechanical retrofitters might also repair the HVAC and refrigeration systems in the facility. Often, when there is trouble with an existing system, the system components can be repaired instead of replacing or buying a new system. The retrofitters’ knowledge of the components allow for a qualified diagnosis of the problem and recommendation for repair. Of the options, repairing the system is the most environmentally friendly.

Whether the decision is to install new equipment, replace components or repair the existing system, using a qualified mechanical retrofitting specialist will provide the assurance that work done on the mechanical system is in keeping with industry standards. Using quality parts and systems with increased efficiencies help keep operational costs lower. They can also have the added benefit of keeping the environmental impacts lower.

Commercial HVAC Services in Silicon Valley

HVAC services are important all year round, especially in the summer, for Silicon Valley businesses. Records show some summer temperatures recorded as high as 105°. This makes commercial HVAC’s having to work overtime to maintain a reasonable temperature for their customers. As a result, it is extremely important to keep the HVAC working at its highest efficiency at all times.

Choosing the Right HVAC

There are a number of HVAC units on the market today with a wide assortment of sizes and prices. Having the right size for your establishment will assure that the proper amount of warm or cool air will automatically turn on when required.

The choice of the size of the unit needed, for your particular establishment, should be determined by an expert HVAC technician. The square footage of the amount of space to be cooled or heated, the number of ducts required, the location of controls and other feature are involved.

These units can vary in price from $2,500 to $12,000, or more, depending on the size of the building. Each unit has specific features, which should be understood prior to purchase. You should always insist on a unit that meets the Energy Star® regulations. Units meeting these requirements have money saving features.

As a rule, the company that sells you the HVAC unit also does the installing. All costs, regarding the price of the unit and installation, should be provided in a free estimate, by the HVAC Company, at the beginning of the transition.

Installation

Once you have had a trained HVAC expert chart out your building, he or she will be able to tell you the number of BTU’s that are required to provide adequate heat and cooling to your building. They will also determine location of registers and ducts. Care should be taken in the location of the controls. Larger commercial buildings usually have these controls located in more than one place.

Maintenance

Once the unit is installed and working correctly, it is important to have a yearly maintenance check. This will help avoid unexpected breakdowns, which can be a disaster in a retail establishment. One of these maintenance jobs is cleaning the ducts.

Many people do not realize that ducts can accumulate dust mites, pollen and other things that can cause problems with customers or employees who suffer from allergies or other breathing problems. HVAC experts should clean these ducts at least once a year to avoid this situation.

When contracting with an HVAC Company it is important to determine their guarantees, emergency service, insurance, bonding and affordable pricing. This will help avoid any misunderstandings later.

Learning About Bay Area Commercial HVAC Retrofit

Retrofitting Your HVAC System

HVAC systems need to be replaced after being used for a certain period. This depends on the maintenance. Replacinthe HVAC system takes up a lot of resources and time because of the complexity of the operation. It is important to make sure that everything is done perfectly to prevent unnecessary disruptions. The installation of the HVAC retrofit should be in such a way that it is able to work efficiently. This will improve productivity and will result in fluid operations.

Installing New Systems

The most common way of replacing an old system is replacing it with a new one of the same type. People usually gets another part of the same make and size if one of the parts needs to be replaced. This is getting harder today because the old models might not be available. The HVAC system is set up according to the structure of the particular building when it is installed.

Most systems have a lifetime of around 20 years. The needs of the building could have evolved. This means that this type of replacement will not work because you need to consider the changes. The state of the building should determine the retrofit when conducting an overhaul.

Newer Components

HVAC systems continue to get better as technology improves. These new components are more efficient and more effective than the older ones. Some of the new features include alternative-fuel chillers, variable frequency drives, and building automation systems. It is advisable to look at newer technologies when doing a retrofit because it could mean cheaper energy costs and more efficiency. Chillers consume a lot of electricity in many buildings.

There are two things to consider when looking for a chiller. These include the full-load efficiency rating and the part-load performance. The full-load efficiency rating is quoted the most, but it is not very important because chillers operate at full load for a minimal amount of time. They work under part-load conditions. You should consider the part-load efficiency because it will have a big effect on the energy usage. Chillers that have higher part-load efficiencies are more expensive, but they usually pay off in the long run. High maintenance costs are a sign that the HVAC system is getting old and might need a replacement.

Our Experience

We have worked with many clients in the Bay Area. We have delivered good results to them each time. We are experienced professionals. We always put the needs of the customer first when we do our job.

Important Things to Know About Industrial Green HVAC Systems

Homeowners are increasingly looking for means to maximize the efficiency of devices and equipment in their homes in an attempt to reduce the adverse environmental impact and also reduce the operational costs. The HVAC industry is slowly responding to the increasing demands for green products with an emphasis on producing high-efficiency HVAC systems that are not only environmentally friendly but also save on energy bills while keeping homes warm and with clean air.

The Environmental Protection agency enacted a regulation in 2010 that requires all the heating and cooling equipment manufactured to use R-410a refrigerant. Unlike other refrigerants, R-410a does not contribute to the depletion of ozone layer. The older units that operate on Freon or R-22 will still be serviced, and the Freon refrigerant will be manufactured until 2020.

However, the cost of Freon is projected to rise in the next ten years, which is a way of discouraging companies from using the refrigerant in the heating and cooling units. Unlike Freon, the R410a refrigerant does not negatively impact the environment, and it helps to cut power consumption by the HVAC systems. Here are top three things you need to know about Green HVAC systems.

They can reduce power costs up to 40%

There has been an increase in energy costs over the recent few years and homeowners and industries have been on the lookout for alternative ways that will cut their running costs. With the green HVAC system, homeowners and manufacturers can reduce the power bill by up to 40 percent. It has been a relief to companies that have been paying massive amounts for electricity bills.

They clean the air better than the traditional units

Green HVAC systems have been shown to reduce air, acoustical, and thermal pollution. Most of these units are made using the latest technology so they can filter the air better than the traditional units. That creates a better environment to live in especially for individuals suffering from allergies. They can get rid of pollen and other suspended matter that can trigger allergic reactions.

They are quieter than traditional units

One of the nerves wrecking things about the traditional HVAC systems is the amount of noise they produce when they are operating. The noise increases when dirt accumulates on the filters. On the other hand, industrial green HVAC units produce less noise and also consume less energy. They are increasingly being used in hospitals to condition the air since they do not disturb patients.
