What Options Do You Have for Green HVAC Systems?

What Options Do You Have for Green HVAC Systems?

If you are concerned about the environment, you have plenty of options regarding going green with your heating, ventilation, and air conditioning (HVAC) systems. There are a number of ways you can replace your current HVAC system and allow your home to be more environmentally friendly. Some of these options include hybrid solutions and heat pumps.

Types of Green HVAC Systems

Heat pumps are typically one of the most environmentally friendly heating options. Heat pumps are extremely energy efficient. Heat pumps are able to save more energy than traditional furnaces and air conditioners due to the fact that they transfer heat instead of generating it through electricity. During the cooler months, air source heat pumps transfer heat from outside your home into your home. In the Summer, heat pumps move heat from inside your home to the outdoors. Heat pumps are also better equipped to remove humidity from the air than traditional air conditioners. Further, heat pumps cost 25% less to run than traditional air conditioners and furnaces. This means you will save approximately 30% to 40% in energy costs.

Hybrid Heating systems are another environmentally friendly option to cool and heat your home. These systems are made up of carrier’s infinity control technology, gas furnace, and a heat pump. Hybrid heating systems are able to shift between gas or electric energy sources based on the weather conditions outside your home. This type of system is able to determine the temperature outside your home and then select the type of energy source that is the most efficient in cost.

Programmable thermostats are also an excellent way to save costs as well as increase the level of environmental friendliness of your home. Programmable thermostats are able to adjust the level of energy your home is consuming by arranging the HVAC unit’s on and off cycles with your unique schedule, which allows for more control over the temperature within your home. Programmable thermostats are able to be programmed through wi-fi or remote access as well. This will allow you to set the temperature of your home from a device such as a tablet, smartphone, or computer.

What’s the Average Price of a Central Air Compressor?

Whether you’re upgrading an existing HVAC system or installing one for the first time, it’s good to have some idea about what you’ll spend on key components. Let’s start with the central air processor, the heart of any HVAC system. A quick search online might suggest that $1,500-2,000 is a reasonable starting budget for parts and labor, but typically these sources are referring to residential air conditioning.

What about the needs of businesses? It’s harder to find relevant information, and for good reason: the criteria for business HVAC systems are both more varied and more exacting in nature. That’s why, like most contractors, we encourage you to contact us directly and discuss your unique needs with us. Because when it comes to your business, there’s a better question than wondering what’s average:

What’s the best available solution for your specific needs?

Residential HVAC often employs a more “one size fits all” approach, which makes it easier to quantify in general terms and averages. On the other end of the spectrum, HVAC systems for multistory buildings and massive warehouses often demand specialty solutions.

The industrial-grade air compressors required in these situations can cost upwards of $10,000-15,000 apiece. But what about small to medium-sized businesses? Though you may not need industrial-grade equipment, your business will almost certainly benefit from a more personalized plan. Consider some of the unique needs of businesses:

  • maintaining multiple zones of climate
  • quick response to thermostat changes
  • quiet, unobtrusive operation
  • larger total space to cover

It’s easy to see how the average residential solution falls well short of these needs. But you can at least gain some idea of how powerful the compressor should be. This mainly comes down to the total space covered and the climate your business resides in.

For example, in San Jose and surrounding areas, a good rule of thumb is to seek 0.5 tons of capacity in the compressor for every 300-400 square feet of your business. However, you’ll ultimately want more than a rough estimate, to avoid both overspending and underserving the needs of the building’s occupants.

If you’re ready to take the guesswork out of the equation, call us at 408-295-2182. We’re happy to help you discover a solution which is anything but average.

Should a Bad AC Compressor be Repaired or Replaced

If you notice that your air conditioner is not blowing cold air out, you are going to need professional help. Strange sounds, warm air coming out of your unit, and strange noises can all be signs that you have a problem with your compressor. There are a few different factors to consider before determining if you need to repair or replace your compressor. Since this is a big investment, it is important to get professional assistance with this type of issue.

Factors to Consider:
. The age of your unit
. Repair or replacement costs
. If it has broken down a lot over the years
. If you are interested in a more energy efficient Unit

To Repair or Replace Your AC Compressor

You need to take the age of your unit into consideration before you decide to repair or replace your compressor. If your unit is older, you may want to invest in a new unit. If your unit is relatively new, it might be a better investment to just have your compressor repaired.

Cost can be another factor. In some cases, it may be cheaper to just have your AC compressor repaired. In other cases, it might be cheaper to have it replaced. The costs will depend on your unique situation, and a professional company can help you understand everything that is involved in the repair and replacement process.

You should also think about how many times your compressor has broken down over the years. Think about how long your unit is going to last after you have your compressor repaired.. Older units will start to have other problems and may still need other repairs shortly after the compressor has been repaired. It might be a better option to have your unit replaced if your compressor or other parts of your AC unit have been acting up a lot.

New air conditioning units offer more energy efficiency. If you are interested in a more energy efficient choice, a new unit will help you save money on your energy bills each month.

How Expensive Can You Expect an Air Conditioning Compressor Replacement to Be?

HVAC systems are not designed to last forever. At some point, you will need to have parts in yours repaired or replaced.

Before you have your air compressor replaced, you may want to find out how much it will cost you. You can plan for paying for this part by learning what factors can determine the price for this part.

Size of the Air Conditioner

The size of the air conditioner will determine in part how much you will pay for your compressor. As a rule of thumb, the bigger your air conditioner is, the more you will pay for a replacement compressor.

This rule applies because of the demand put on the compressor inside of the unit. It will need to be large and powerful enough to draw in coolant from the outside and move it to the inside system to cool the air in the building. Larger air compressors cost more than smaller ones used in less powerful AC units.

Length of Warranty

Most new compressors come with warranties that can last up to 10 years. The price you pay for a replacement will depend on whether or not the warranty is still in place on the one you need to replace. If the warranty is still active, you could get this part replaced for little to no cost.

However, if the warranty is no longer good, you will need to pay for the replacement compressor out of your own pocket. You may need to save up money for it or even secure some type of financing to pay for it.

HVAC Contractor Fees

Replacing a compressor in an air conditioner takes skills you may not have. In fact, working on an HVAC system requires a certain amount of knowledge and experience that most home and business owners lack. You may need to hire a contractor for the job.

The amount of money you ultimately pay for a replacement compressor will depend on how much the contractor charges you. The final price will include not only the price for the part but also the hourly labor rates for the contractor’s service.

Before you hire a contractor, you should make sure he or she:

  • Has been in business at least 10 years
  • Is licensed and insured
  • Has good customer reviews

These qualifications could help you get the best rates for replacing a compressor. Replacing a compressor does not have to break your budget. You can find out more about its cost by calling 408-295-2182.

How Important Is Air Conditioning in San Jose?

For those who live in the San Jose area, you know all too well how hot the temperatures can sometimes rise. While hiding beneath the shade can sometimes offer relief from the baking sun, it doesn’t do much for the actual temperature. One certain method for relief is air conditioning. A business, university, or even a residential home should be equipped with a high-quality air conditioning unit in San Jose. This article will discuss the reasons and benefits that you can receive when you have an AC unit installed.

Advantages of Air Conditioning

Limit Dehydration: When the temperatures rise, your body sweats in an effort to cool itself down. Most of the sweat that is removed is water that exists in your body. Once that water is depleted, you can start to suffer from dehydration. In some cases, the side effects of dehydration can require you to receive treatment at the hospital. This is because your life may be in danger. Without water, your body can no longer perform certain functions and starts to give out. An AC unit keeps the area cool which limits the amount of sweating that is performed. Less sweating means less of a chance of becoming dehydrated.

Reduced Building Damage: Just like a person, heat can also damage the interior of a building. Most of the materials used for the interior of a building rely on certain temperatures to help it maintain its structure and integrity. With a high temperature, those materials can start to degrade and fall apart. For owners of the building, you likely don’t want to have to spend money making repairs every time you experience a particularly hot summer. Investing in an air conditioning unit can increase the longevity of the interior of the building.

Limit Heat Sickness: Did you know that you can get sick just from being hot? One of the problems that being dehydrated can lead to is heat sickness or heat exhaustion. Trapped in a stuffy room, you might succumb to heat exhaustion and pass out. If no one is there to help you, then you might perish. For businesses, no one wants their customers to have a life-threatening experience in their store. Air conditioning can ward off the chance of that happening.

What Can You Expect to Pay for Your Central Air Conditioning Compressor?

Air conditioning is a convenience you may not want to go without this summer. However, when your AC unit no longer works as expected, it may be time to replace its compressor.

Before you decide whether or not to replace the central air conditioner compressor, you may want to know more about this part. This information could allow you to price it accordingly and determine if it is a better investment than replacing the entire AC unit.

What is an Air Conditioner Compressor?

The compressor in a central air conditioner is a part that is responsible for moving the refrigerant from the outside unit into the unit inside of the home. When it functions properly, the compressor accomplishes this in a continuous cycle so your home is never too warm and always has a low level of humidity.

However, this part is subject to wear and tear over time. If it comes into contact with excessive amounts of dirt and debris or is exposed to electrical hazards, for example, it can quickly wear out and need to be replaced.

Pricing a Compressor

Central air conditioner compressors can be more costly than other parts because of the role they play in the AC unit. Their price also reflects the amount of time it takes to replace them, which can be as long as four to five hours.

Their price also depends on the number of stages they contain. Single stage compressors cost less than two or multi-stage compressors. However, multi-stage compressors are often worth the investment because they keep your utility bills low and also lower the humidity level in the home.

Replacing the Compressor versus the Entire Unit

In some circumstances, it may be more cost effective to replace the entire AC unit. If the air conditioner is 10 years old or older, you may decide to replace the entire unit. Putting a new compressor in an older AC unit will only cause it to malfunction. The old unit may not be able to accommodate the new compressor sufficiently.

If the compressor is under three years old, it may still be under warranty. You could have it replaced at little to no cost. If the compressor is between three to 10 years old, you should base your replacement decision on how often the entire unit malfunctions.

Pricing a central air conditioner compressor could save you time and hassle in fixing your AC unit. Learn more about compressor replacements by calling us at 408-295-2182 today.

What Is Industrial Air Handling and Why Is It Important?

Industrial air handlers are used to condition air so that it’s clean and help circulate it properly throughout the building. The devices are essential to keeping the environment cool or warm and maintaining the comfort of industrial workers. Their long-term health and safety depend on the efficiency of these systems. Learn more about the importance of using air handlers.

The Purpose of Air Handlers

Air handling units are designed to circulate air throughout a heating/cooling system. Industrial air handlers are designed for use in industrial settings like warehouses, factories and manufacturing plants. Some units are placed on rooftops, while others are designed to condition outdoor air only. Industrial systems are large, run for days or weeks at a time and must be maintained regularly.

Parts of the System

Most units contain the same components, such as fans, coils, filters and supply ducts, as residential air conditioners. The air filters are designed to clean the air that passes through, and the heating exchange coils are made to regulate the temperature.

An air handler contains a humidifier that improves the air quality. The efficiency of a humidifier is reduced when the air filter becomes clogged. So, maintaining an air handling unit regularly is important for it to run properly.

Some air handlers have mixing chambers that combine warm and cool air, which helps to regulate the temperature. Dampers are used to control the amount of air that enters or exits the building.

Mechanical fans or blowers are used to increase the airflow. In an industrial unit, multiple fans are seen that run at different speeds. In some buildings, heat recovery devices are used to recover heat loss and reduce the amounts of energy usage.

An air handler is managed using a wide range of controls. One control is designed to increase or decrease the rate of airflow. Another control is used to regulate the temperature or humidity levels. Some handlers are connected to automation systems that control the entire building.

Industrial air handling is necessary to run a clean, healthy plant or factory where heavy-duty manufacturing is taking place. During the manufacturing process, all types of fumes and debris are released into the air. Look for different selections of air handling units that vary by size, types of controls and setting. It’s important to find the right product that fits your specifications. Contact our company at 408-295-2182 to see how we can help you.

What’s the Best Type of New AC Compressor?

When you need to replace the compressor in your air conditioner unit, you might wonder what kind you should choose. You want to select a compressor that will perform well and keep your building cool

However, you also may want it to lower your utility bills and not make a lot of noise while it functions. You can decide what type of air compressor is best for your building by learning about the available models.

Centrifugal Air Compressor

A centrifugal air compressor uses centrifugal force to move around refrigerant in the unit. It uses this force to pull in the coolant before rapidly spinning it with the impeller in order to compress it.

A centrifugal compressor is ideal for using in extra large HVAC systems. If your building uses a large air conditioner unit, you may decide that a centrifugal air compressor is right for your needs.

Rotary Air Compressor

A rotary air compressor can be the perfect choice if you are concerned about noise. When you want a quiet air compressor, the rotary model may suit you well because it:

  • Is small and quiet
  • Contains a shaft with several blades attached to it
  • Pushes coolant through the cylinder while compressing it at the same time


If you prefer your air conditioner function as quietly as possible, you could reduce the noise level without sacrificing the service of the unit by installing a rotary air compressor in it.

Screw Air Compressor

The screw air compressor has a reputation for being reliable and efficient. It is typically used in large buildings where substantial amounts of air need to be continuously cooled.

The screw air compressor has two large helical rotors that move the air in the unit from one end to the other. When the air moves through the compressor, the space gets smaller and the air gets compressed.

Reciprocating Air Compressor

The reciprocating air compressor is perhaps the most popular model available today. It has a piston that moves air up and down inside of the unit’s cylinder.

As it moves the air down, it creates a vacuum that sucks in refrigerant. As the air moves up, the gas compresses and moves into the condenser.

These models are the most common types of air compressors on the market. You can find out more about your choices by calling 408-295-2182 today.

How Big Of A Job Is It to Replace AC?

Replacing an air conditioner is one of the most complicated processes you’ll encounter as a homeowner. The project starts when you meet with one of our representatives to the final steps when we test the new system for optimal performance.

What’s Involved

The first step involves a thorough home assessment to find the best size for your system. The amount of insulation you have throughout makes a difference, as do the number, types and sizes of the windows. The floorplan layout and its total cubic footage are included in the analysis, which involves using software called Manual J to give us the right size for your new system.

If the system you select is too large, it will run in short cycles. Instead of saving energy, an oversized system actually uses more energy. It won’t run long enough to cool the parts of your home that are further from the air handler or thermostat and it will leave excessive humidity behind. An oversized system will also start more frequently, which uses a lot more electricity than the AC uses in mid-cycle.

Next Steps

Once the team has the size of the system, they move onto inspecting the ductwork to verify that it’s the right size, in good shape and free from air leaks. They use Manual J’s sister software called Manual D to size it. The team has testing equipment to identify where and how large any ductwork leaks are. As part of the inspection, they look for excessive dust inside the ducts and weaknesses.

Installation Day

At least one adult will need to be home during the installation that will probably take the greater part of the day. The first steps are to install the outdoor condenser and the indoor air handler. Next comes the wiring and attaching the air handler to the ductwork.

The technicians use their tools to verify that all the components are receiving the right amount of electricity and functioning as they should. They check the refrigerant pressure several times during the installation process. They’ll also use their tools to make sure that the air leakage rates through the ducts meet local and state guidelines.

When Do You Need a Replacement AC Compressor Instead of a Repair?

A central air conditioner can be pricey to maintain and repair. Given the expense of keeping it in good condition, you may welcome the opportunity to replace faulty parts rather than have the entire unit serviced.

However, you might wonder in what cases you should buy a replacement compressor rather than have your air conditioner or its components fixed. You can make this decision confidently by learning when it is better to replace the air conditioner compressor instead of having it repaired.

Length of Warranty

Most parts in a central air conditioner are covered by warranties for finite amounts of time. The amount of time that a warranty covers a part varies. However, most warranties last for at least three years if not longer.

Before you decide whether or not to have your central air compressor replaced or fixed, you should find out if it is under warranty. If it is still covered by this protection, you could have it serviced at no cost. The company that extends the warranty to it may repair it for free.

Depending on the damage, the warranty may also cover a brand new replacement at no cost to you. The warranty on the new part would then begin anew once the compressor is installed in the central air conditioner.

Age of the Air Conditione

The age of the central air conditioner also should influence whether or not you have the compressor replaced or repaired. In many cases, there is no sense in having an aged part in an older model unit repaired. Both the unit and the part are prone to breaking down sooner or later, which essentially wastes your money.

However, if the air conditioner is younger than 10 years old, you could have the compressor repaired with a relative degree of confidence. The age of the air conditioner should not present a threat to the compressor. You could get a good amount of wear and tear out of both before you need to have them replaced.

Compressors between the age of three and 10 can be either replaced or repaired. You may opt for replacement if the compressor is leaking, however. A leak in the compressor is indicated by symptoms like:

  • Rattling in the outdoor unit
  • The AC unit tripping the circuit breaker
  • A scent of chloroform around the outdoor unit
