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’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.

How Much Should I Pay For A New AC Compressor?

The air compressor is one of the four main parts found inside an air conditioning unit. It compresses refrigerant gas called Freon by exposing it to high temperatures and pressure. This heated and pressurized gas forces cooler air throughout your air conditioning system through ducts.

The leftover hot air is then transferred to the outside via coils and a fan. Without a functioning compressor component, an air conditioning unit will not work. There are many reasons why a compressor is no longer working.

Here are some of them:

  • If an HVAC system is poorly maintained, it will cause wear and tear to the AC components including the compressor
  • power surges can damage the compressor and cause it to burn out
  • too much moisture in the air can cause chemical reactions that will wear away the compressor
  • a compressor may stop working if it is defective, damaged during other repair work or past its lifespan

You can help prevent damage to the compressor and extend the life of your AC unit by doing basic maintenance. Annual AC tune-ups, changing your air filters on a regular basis, cleaning the HVAC system and controlling moisture levels can all prevent damage and wear to the compressor.

How Much Will It Cost To Replace A Compressor In An AC Unit?

Sometimes, an air compressor will stop working and need to be replaced. Since it is essential to the operation of the air conditioning system, you will have to replace the compressor or get an entirely new HVAC system. Often the most economical and smart decisions you can make is just to replace the compressor.

Generally, the larger your AC unit is, the more expensive the replacement compressor will cost. For example, a 2.5-ton capacity air conditioner unit will have a replacement cost of about $500-$980. A 5.0-ton capacity AC system will have an estimated cost of about $815-$1600 dollars.

Air compressors vary in quality. A cheaper compressor may save you money, but it will have a shorter warranty period and will not last as long as a more expensive one. Taking this into consideration is important when selecting a compressor.

Another important thing to factor in when shopping for a new air compressor is the installation cost. If you have staff on hand that can install new parts in an old air conditioner, then the additional installation cost will not apply to you. If you lack such staff on hand, then you can expect to pay an additional cost for installation. The installation cost should be around the same price as the compressor.

We will quickly determine what kind of compressor is required for your AC unit. Our team will also work with you to schedule a convenient installation time. Call us today at 408-295-2182, and we will get to work right away on getting your AC up and running.

How Air Handlers Actually “Handle” Air in Your AC System

What do air handlers do for your air conditioning system? It, quite simply, handles the air. What does this entail? Most air conditioning units, especially in Silicon Valley, are “split” units. This means that they have units both outdoors and indoors. The air handler covers the indoor section of the air conditioning system which is extremely vital.

The role of the handler is to distribute the air through the entire house. The handler unit for indoor air is made of an air coil, blower and filter. The handler brings air in, flows it through the coils (to heat or cool) and then expels it back into the house with the duct system. It is the portion of the AC system that makes sure the air that gets treated flows throughout the entire home.

Air Handler Parts

  • Blower The fan blower will “blow” the rest of the cooled air back throughout the home by using the duct ventilation system.
  • Air filter This filter is placed between the fan and the intake vent to make sure that the air brought into the unit is filtered before it gets cooled.
  • Coils The coils are what truly cool the air inside the house. This occurs when the housed refrigerant within the external unit is drawn out as a high-pressure and high-temperature gas into the internal air handler. A valve then transforms this gas refrigerant into a low-pressure and low-temperature gas that’s brought to the coils. These coils then make the air cooler that’s getting passed over the coils and into the system of ducts. This “used” refrigerant is brought back outside to the external system to start the cycle once again. In the majority of homes in Silicon Valley, the coils can get hotter as well to provide the “heating” portion of a home’s HVAC system.

Would it be helpful for you to use an air handler?

When you use a split-system heat pump or air conditioner, then yes, you would want to use an air handler. The air handler will make sure the air involved in the cooling or heating process is circulating. It’s the indoor component that handles air in conjunction with the outdoor part.

The evaporator coil will bring the heat out from the building to then blow the cooled air through a set of ducts in the building that are connected with the air handler. Call O.C.

When Should You Call an AC Repair Service?

The best time to check your AC unit is before a breakdown. It is understandable that taking the time to do this might not be something you are comfortable doing. Things you can do yourself that might help save time and money later are included here. AC repair performed by a professional isn’t cheap, so do what you can to prevent a large repair bill by making sure to care for the basic things in your AC unit before calling for service.

If you find that your unit isn’t working, many symptoms can lead to a repair. Some symptoms result from not cleaning your filter, or by allowing vegetation to grow over and around your outside AC unit. Cleaning your filter and clearing the area around the AC unit is easy to do and could save you an unexpected repair bill.

Common Reasons AC Units Require Repair

Let’s inspect common reasons to call for AC repair service:

  • Perhaps the most obvious problem you’ll notice is your AC unit has ice built up around the copper lines. This is typical of a unit with poor air flow among other issues.
  • Inside the home, if you notice the air flowing from the ducts isn’t as cold as it once was, your AC might be low on Freon due to a leak. There are more reasons for a no-cool issue and means you must call for service.
  • Your AC unit cycles on and off as part of its normal operation. If it cycles frequently, look outside at the unit. Something there might show the problem.
  • In the event your unit stops running for no clear reason, check the breaker at your breaker box inside your house or at the unit to see if it’s tripped. When breakers get old, they sometimes trip for no reason. Reset the breaker regardless if it looks tripped or not. Confirm the breaker is at its full-on position (not half way). Check the unit to see if it runs now.
  • The air from your AC unit shouldn’t smell or give off a foul odor. If it does, please turn the unit off at the breaker and make that call for service. The problem might be in your duct work, or something inside the unit itself.

Keep in mind that other issues could cause the AC unit to either not cool or stop running. Use the tips provided here to help determine whether it’s time to call for service or to clean the filter or the vegetation around the unit outside. As a final tip, verify that your thermostat isn’t the cause of a failed system.

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.
