Is It Cheaper to Replace My AC Compressor or Just Get a New Air Conditioner?

There are many factors that come into play when you are trying to decide whether to just replace your compressor or to replace your entire unit. You want to make an informed decision that will be the best choice for your needs. By talking with a professional, you can learn which choice will be right for you.

Think About These Factors:
. Find out if your compressor is under warranty
. Learn if just replacing your compressor will mess up your energy efficiency
. Consider the fact that replacing your compressor without replacing your entire inside and outside unit could cause your unit to not last as long as it should
. Figure out if there is a big price difference in replacing your compressor and going ahead and just replacing your entire unit

Choose a New Compressor or a New AC Unit

To figure out if it would be cheaper to replace just your compressor or to replace your entire unit, you need to take warranties into consideration. Find out if your compressor is under warranty. If it is, it may be cheaper to have it replaced then to put out the money for a whole new unit.

Think about every factor including your energy efficiency. If you just replace your compressor, you may end up paying more in energy bills down the road. If you invest in a whole new unit, you will be getting the latest technology and a more energy efficient model.

If you just replace your compressor, your AC unit may not last as long as it should. You could be dealing with other problems in the future that will end up costing more money. If you do not fix each problem, your unit might not last as long as it should.

Talk with a professional company to see what the costs are to cost the compressor and what the costs will be to replace your entire unit. You may find out that there is not much of a price difference. An AC compressor is an expensive part of your unit. You should also consider the age of your unit before you invest too much into it. You could be better off just buying a new unit if yours is an older model.

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.

Call our friendly staff today at 408-295-2182 to get started in investing in your business with a quality AC unit and service.

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.

How Much Can You Expect an Air Conditioner Compressor to Cost?

The home ac compressor unit is one of the integral parts of the central air conditioning system. Installing your compressor is a significant project. The cost of the compressor will also depend on whether you want to install a new one or if you want a replacement. Replacement costs will also consider whether your old compressor is still under warranty or if it is over eight years old.

The comparison between the cost of replacing a complete ac and coil or the evaporator coil helps to determine whether it will make more sense to replace other than repairing the ac compressor. An additional cost to consider is the labor cost that you will incur for installation. Therefore, below is a review of the amount you can expect to pay for an air conditioner compressor.

AC Compressor Cost Factors

The cost of replacing a compressor for your home AC system is dependent on certain factors. These factors include:

  • The availability of a warranty for the compressor parts
  • The size of the AC compressor
  • The type of compressor and,
  • The consumer brand ratings

Usually, the warranty covers the cost of the parts. Replacing an Air Conditioner Compressor that is still under warranty will incur an average cost of around 645 dollars. If the air Conditioner Compressor is not under warranty, buying a new one will cost you an approximated amount of 1280 dollars inclusive of the installation cost.

Additional supplies are also needed. In most cases, the supplies are never warranted even though the air conditioning compressor might be warranted. Below is a list of the supplies and their cost:

  • Cost of Installation Supplies
  • Copper fittings and connectors with the cost between 35 to 100 dollars
  • Line filter or dryer with the cost between 35 to 75 dollars
  • Contractor, capacitor and hard start kit with the price between 35 to 150 dollars
  • Misc silver solder, electrical connectors with the price between 15 to 25 dollars
  • Refrigerant recharge with the price between 150 to 300 dollars

AC Compressor Installation Cost

You will also incur labor cost or a diagnostic fee unless the compressor is under warranty. A diagnostic fee ranges between 59 and 129 dollars. The typical cost for a service technician ranges between 60 to 90 dollars per hour, and the service helper is paid 60 to 75 dollars per hour.

When Is It Time for an Air Conditioner Compressor Replacement?

At some point, your air conditioning unit will need to be replaced. With age comes the need for increased repairs, efficiency issues, and other problems. It is important to make sure that you know when it is time for an air conditioner compressor replacement.

There are several things that you should consider when thinking about replacing your air conditioning.

  • Age. Consider the age of your unit. If your unit is just a few years old, you may be better off just to have it repaired. If you have a much older model, it will be more difficult to find the parts needed, and the general well being of the machine may be compromised. If your unit is over 15 years old, you may automatically want to consider replacement.
  • Energy efficiency. Running your HVAC unit will make your power go up as they use a lot of power. However, there are many newer models out on the market today that is very energy efficient. If your unit is 10 years or older, you may want to consider switching to a newer model as they are more energy efficient, and can help to lower your energy costs.
  • R-22. If your unit uses R-22 refrigerant which is also known as Freon, you will need to consider getting a replacement unit. The EPA is phasing out R-22, and that has made it very expensive to get. A pound of Freon can cost anywhere from $40-$175 depending on the location. For people who have a leak, the repair could quickly get up to $1,000. The newer refrigerant is environmentally friendly, and will completely replace R-22. Consider switching to an R-410A refrigerant.

Other Factors That May Factor in When You Consider Replacement

There are also some other factors that you may want to consider when deciding whether it is time to replace your compressor. Take into consideration how many times you make repairs on the unit.

If you are constantly making repairs, it is time for an upgrade. You will also want to consider your energy bills, and whether or not your house is too hot during those hot summer months. If you need help in deciding whether or not your unit needs to be replaced, call a professional HVAC company that can help you to determine whether or not you should get a new unit. We can help you immediately. Call us now at (408) 295-2182.

How Does an HVAC System Work?

Most modern homes and buildings have efficient heating ventilation and cooling (HVAC) systems that keep people comfortable at various times of the year. It’s probably something you take for granted, but there may come a time when you want to know a little more about how these systems work. The most essential step for understanding an HVAC system is to learn about its anatomy. There are six main parts to the system:

  • Thermostat
  • Furnace
  • Evaporator coil
  • Condensing unit
  • Refrigerant lines
  • Vents

The thermostat is the control panel where you adjust your desired temperature. It measures the air temperature and it can automatically adjust the heating or air conditioning to emit either cool or warm air as needed.

Furnaces produce heat that is blown through the ductwork to heat the building. They can use a variety of different methods to produce heat such as combustion, electric resistance and solar energy.

The Evaporator coil’s purpose is to cool the air. The process of evaporation transfers heat from the air into the liquid compound inside the metal coils, which causes the air around the coils to become cooler.

The condensing unit is filled with a refrigerant in a gas state that is cooled to a liquid state, then pumped into the evaporator coils. This serves to release heat energy that was absorbed by the evaporator coil.

The Refrigerant lines carry a chemical compound in a gas state from the evaporator coil to the condenser coil where the gas is turned back into a liquid and heat is expelled from the system.

The vents are the points where warm or cool air are released into the living or working spaces of the building. They’re rectangular openings with metal slats, and they’re usually located on or near the ceiling.

Three types of HVAC systems

There are many different types of systems to control air temperature, but these are three of the most common types.

  • Split systems
  • Duct-free systems
  • Zoned systems

Split systems have components on the inside and outside of the building. They usually have a furnace, an air conditioner and ductwork to carry air throughout the building.

Duct-free systems circulate air throughout the home or building without duct work by using pipes and fans, and zoned systems allow you to set different temperatures for specific areas or rooms in the building.

What happens if you don’t replace your broken ac compressor?

You don’t think about them when they are working properly and cooling your home and business, keeping you comfortable on the hottest of summer days.

But, then it happens: Your unit breaks down and suddenly the interior temperature of your home or business rivals that of the outside, leaving you wondering exactly what’s going on with your air conditioner.

One of the most common causes of a malfunctioning air conditioner is a failing compressor. And this is something you simply can not afford to ignore or ride out until the return of cooler weather in the fall and winter, for both financial and health reasons.

What exactly is an ac compressor? It is the part of the air conditioning unit that transforms the refrigerant chemicals from liquid to gas and back to liquid in a never ending cycle that produces cold air.

Signs of a failing ac compressor

Never fear. Your air conditioner’s compressor will not fail on you without warning. Here are some signs of potential compressor failure:

Just before it fails, compressor will begin hard-starting or struggling to switch on. You may hear a chattering or rattling noise, which could be signaling a problem with the unit’s compressor.

If you notice a clicking sound when the unit turns on, that could mean that the compressor’s motor mounts have worn out. When that happens, the motor that cool air from inside the compressor has become loose and is moving round inside the seal case that encloses it.

Puddles or moisture around any part of your ac unit could also be a symptom of compressor failure. Refrigerant could be leaking out of the compressor and that could lead to potential health concerns such as coughs, headaches, irritated eyes and nausea. If all the refrigerant leaks out, it could cause the unit to overheat.

More subtle signs of ac compressor failure include reduced air coming from vents; warm air coming from vents; and a unit that is running virtually constantly. All of which will lead to an increased power bill if the compressor is not repaired.

The heart of your ac unit is the compressor, which contains both chemical and electrical components. When functioning properly, you won’t even notice that it is doing its job.

But if its not and you are ready to get it fixed, call us at 408-295-2182.
