What Air Conditioner Repairs Require a Contractor or Other Repair Technician?

Having purchased an air conditioner unit, it’s every homeowner’s dream to experience unrivaled comfort in their home during the summer and winter season. The unique ability to regulate both warm and cool air undoubtedly promotes healthy living and creativity. Despite their substantial benefits, air conditioners tend to break down once in a while and fixing them can be a daunting task, especially to first time owners. The constant debate of whether to consult an air conditioner contractor or simply fixing it by yourself can ultimately push you over the edge. As a homeowner, you might want to get acquainted with several repairs that immediately demand the attention of a seasoned contractor or repair technician.

Refrigerant Leaks

Refrigerant leaks are critical problems that must be taken seriously to preserve the durability and efficiency of your air conditioner unit. Contrary to common perception, adding refrigerant to a leaking unit doesn’t necessarily fix your HVAC unit. Far from it, such a problem is a manifestation of deep-rooted issues. An air conditioner running on low refrigerant simply denotes that the unit was undercharged during installation. In such a situation, it’s in your best interest to hire a seasoned technician to not only fix the leak but also test the repairs and ascertain that the right levels of refrigerant have been topped up. After all, an air conditioner’s efficiency and performance are optimized when the refrigerant coincides with the manufacturer’s specification.

Broken Compressor Fan

Your air conditioner’s exterior extension consists of a fan, condenser coils, and a compressor. Such apparatuses work in unison to dispense warm air from your home and provide a cool indoor climate. When the outdoor fan is compromised, the heat transfer process is disrupted leading to a subsequent chain of problems. For starters, the air conditioner wouldn’t be in optimal condition to provide cool air while the system’s compressor runs the risk of overheating. With an overheated compressor, your air conditioner’s safety controls can frequently turn your HVAC unit off. By hiring a qualified contractor or repair technician, they shall diligently diagnose the problem and repair or replace your compressor fan if necessary.

Frozen Condenser Coils

When the air conditioner’s condenser coils freeze up, it’s a tell-tale sign that your heating and cooling system won’t run properly. Poor airflow within the cooling system can cause freezing on the coils. Commonly caused by obstructions such as blocked return air ducts and dirty air filters, such issues can be solved with the aid of a refrigerant charge. However, such repairs must be done by an experienced technician who can diagnose the specific problem behind the frozen coils, liquefy the ice and restore your unit’s cooling capacity.

What Are the Signs That Your Furnace Needs Repairs?

How can you prolong the life of your furnace without compromising the quality of their service of having to pay for the power bills through the nose? By ensuring the system is adequately maintained and necessary repairs carried out on time. To achieve this, however, you need to learn how to check on the system and how to identify possible sign that the furnace needs repairs. Note that this doesn’t require special classes, you only need to closely monitor the performance of your system and identify any of these problems:

Inappropriate noise

The almost smooth sound produced by a running heater can be considered appropriate. Inappropriate noise, on the other hand, refers to any strange noise produced by the system during operation. Therefore, should you hear clunking and grinding noises with your system, consider calling in expert repair professionals as this often represents underlying system problems.

System neglect

When is the last time you had your system checked, cleaned, and the air filters repaired? Most furnace manufacturers recommend that you have your system inspected by a professional every three months regardless of its current condition. You should, therefore, consider calling in furnace repair experts if you have neglected it for more than six months.

Poor indoor air quality

Several furnace conditions may contribute to poor indoor air quality. These include dirty or worn out air filters, clogged and dirty ducts or gas leaks from the furnace. Each of these poses health risks to your household thus the need to contact a HVAC repair professional.

Skyrocketing energy bills

How much you spend on heating on a monthly basis can also serve as a great indicator of the current condition of your system. Skyrocketing energy bills are a sign of a stressed system. Stress within a system can, in turn, be attributed to most furnace problems given that its build-up eventually rocks and breaks and down your home’s HVAC system. Calling a repair expert to investigate the disparity in energy consumption, therefore, goes a long way in helping lower the stress and optimize the system performance.

Uneven heat in the house

A properly functioning heater should provide even warmth to all the rooms of the house. Experiencing uneven heat around such as some parts of the house being warmer than the others is, therefore, an indicator of a struggling furnace.

Bottom line

While some of these problems only require soft repairs like cleaning of the air filter, others require extensive part replacement. However, if left unattended, either have the ability to render your system useless, thus the need to contact repair experts as soon as possible. Call us at 408-295-2182.

How Does An Air Handler Work on An AC Unit?

Air handlers are essential to almost all functional HVAC systems. From the stripped back simplicity of cooling a small house, to the large-scale energy transfers required to air-condition commercial real estate – air handlers are everywhere in the world of AC appliances. While the name is self-explanatory, the processes involved are somewhat complex. The main purpose of air handlers is to circulate filtered, conditioned air throughout a building’s ventilation ducts. Each section of the air handler is usually separate from the others, located in a discrete portion of the appliance’s metal body. Though there are varying levels of complexity, air handlers will generally have three essential components.

HVAC Components:

Air Filter: This is usually placed between the intake vent and the coils, making it the first active component. The filtration process ensures that only clean, breathable air is circulated to a building’s occupants. Depending on the level of filtration required, often two or more filters will be placed consecutively.

Coils: These components, which usually take affect directly after filtration, are what heat or cool the air. The air is run over the coils, changing the temperature. The level of heat is manipulated by moving thermal energy between the filtered air and a refrigerant stored in the rest of the HVAC system. This refrigerant is continuously cooled and circulated through the coils, which is what allows the AC to function continuously.

Blower: Once the air has been filtered and the temperature modified, the blower circulates the air through the building. Blowers typically use centrifugal fans powered by electric motors, meaning that their essential function is to change electrical energy into the kinetic energy, which causes the fan blades to rotate. From there, the kinetic energy is transferred from the fan to the air, causing the it to circulate throughout the ventilation ducts.

Given the integral role this technology plays, keeping your air handler functional and effective is absolutely vital to the success of your HVAC air conditioning system. The technology is completely dysfunctional if air is not effectively filtered, conditioned, and circulated. The consequences of poor maintenance range from inefficient waste of energy, to adverse health effects. As such, if there is even a minor problem with your air handler, we can help.

What’s the average cost for a central air compressor?

The four parts used in most central air systems are the compressor, evaporator, expansion valve, and a condenser. Of these parts, the compressor is responsible for circulating coolant through the unit. It does this by compressing freon into a high temperature gas that is then pushed through to the outdoor coil, where at this time the heat is radiated away. From here the coolant returns to liquid form to be pumped back through the interior coils to suck up heat and turn back into gas again. This process cycles over and over again to maintain a cool temperature inside your home or office.

Depending on the model and make of your unit, on average the cost of a replacement compressor can run from anywhere between $300 to $600. However, this is only the cost of the part itself, and hiring a technician will cost you about $1500 to $2000 on average. Seeing the difference in price, it may be incredibly tempting to make a repair job yourself. The caveat is that you need to have an HVAC license in most states to legally work on an air conditioning unit. So while it doesn’t hurt to do further research into what could be a small issue, if it’s something you can’t fix without opening up your air conditioning unit, the chances are that you’ll need to call someone.

Signs a Compressor Needs Replacing

Like many machines, there are several common signs that can tell you whether or not your compressor needs to be replaced by a certified technician. Below is a list of some common problems caused by a faulty compressor. These issues can be caused by wear and tear due to high usage, power surges burning out the circuits of the compressor, or excess moisture buildup causing chemical damage to the unit.

  • The number one sign a compressor needs to be replaced is that your unit no longer blows out cool air.
  • The fan is no longer audible when you turn on your air conditioning unit.
  • Loud noises are coming from the inside of your A/C.
  • The clutch of your air conditioning unit remains still and does not move.
  • Fluid leaks develop at the connectors of your compressor.
  • Dust and other material clogs the compressor’s fan and causes the motor to burn out.

What type of air conditioner repairs can you do yourself?

Have you had your central air unit quit working on you? Have you noticed that it isn’t as cold as it should be? Something may be going on with your appliance that needs some tending to. Air conditioning units are great to have for staying cool on the warm weather days. However, like any other major appliance things can go wrong that will cause it not to work.

You can call in a repair person to diagnose the problem and get it fixed for you. But, if the repair is something minor, you might be able to handle it yourself. Thus, saving you a little money in the long run. Here are a few central air unit problems you could repair on your own, to get your unit working properly again:

  • Poor Air Flow
  • Unit Working Harder Than Normal
  • Blowing out Warm Air Instead of Cold

Air Conditioner Repairs You Can Do Yourself

Change filter- One of the easiest repairs you can do yourself is changing the filter. Filters will get dirty over time. Leaving them that way will cause your air conditioning unit to work harder. Sometimes, it won’t blow cool air at all, because of the dust blocking the filter. Changing it out periodically will keep your unit working efficiently and extend its working life. Check your manual to see which filter you will need and how to replace it.

Clean out condenser coils- Your air conditioning unit, often, will pull in leaves, dirt and other debris. These can stick to the coils, making it work harder. To get your unit working properly again, clean out your condenser coils. Each unit is different, but most can be cleaned out simply with a garden hose. Spray water at the coils to get the debris off, or use a special cleaner that attaches to your garden hose. Be sure to check your owner’s manual to see if there are any special instructions on how to clean it.

Check breaker or thermostat- If you’re experiencing problems with your air conditioning unit, one of the first things you can check is the breaker or the thermostat. It may sound strange, but more times than not, your breaker has tripped or your thermostat isn’t properly set. Check those items first before calling in a repair person. If something trips the breaker, you can un-trip it to get it going again. If the breaker trips again, then you must contact a repair person, because something else is going on that’s electrical in nature. A professional would be the best choice in that scenario.

Repairs to an air conditioning unit don’t always have to be done by a professional. You could do the above minor tips to save yourself a call to a repair person. For major repairs, though, contact a professional to avoid getting yourself hurt or accidentally breaking your coil unit. If you have questions, call us at 408-295-2182.

Prepare Your Home For A Warm Winter With Preventative Heat and AC Repair

You understandably rely on your home’s HVAC system almost year-round for indoor climate control. With heavy, regular use of this equipment, it will become increasingly dirty. Many of its parts may wear out, and fluid levels can decline. Regular maintenance service is recommended as a preventative step for all HVAC systems annually, and a great time to schedule this service is during the fall months before you will heavily rely on it in the winter as a source of necessary warmth.

Preventative maintenance typically includes the identification of parts that are wearing out and should be replaced. In addition to replacing these parts, preventative maintenance includes cleaning various components, replenishing fluids, ensuring that the hose and pipe connections are solid and more.

Important Benefits of Regular HVAC Maintenance

With your heavy reliance of your heat and air system throughout most of the year, keeping your equipment well-maintained is essential. These are a few of the most important benefits that you can enjoy when you schedule preventive repair and maintenance work for your system now:

Maximizing the Life of Your Equipment

All mechanical equipment must receive service in order to function properly and to avoid excessive wear on vital components. Keep in mind that one worn out or dirty part can cause other parts in the system to experience greater wear. This can decrease the longevity of your system overall. By scheduling regular maintenance, you can ensure that all mechanical parts function well.

Saving Energy

When your system does not function efficiently, it may need to operate for longer periods of time during the day to meet your demands. A well-maintained cooling system will function properly and efficiently, which could save you money on energy costs throughout the season and beyond.

Promoting Maximum Uptime

With preventative HVAC service, wear on parts can be identified before they become problematic. When parts are replaced promptly as needed, you may discover that your system has fewer breakdowns.

Increasing Home Safety

Heat and air conditioning systems may develop problems that could become safety issues. For example, gas leaks and carbon monoxides could have fatal consequences. Through maintenance work, these issues could be identified and repaired before they turn into a serious problem.

The best time to schedule preventative work on your HVAC system is before the winter season begins. If you are ready to schedule service, call us today at 408-295-2182

Why Hiring a Local Plumber for a Little Expense Could Save You a Lot Later

If plumbing is not properly done, it can cause premature failure or injury. In the long run, it is more cost effective to hire a professional for minor or major jobs. A licensed professional will also warranty the labor and parts. This is not the case if you do the work yourself.

Plumbing requires knowledge in experience in a wide variety of fields such as:

  • Gas stoves
  • Gas plumbing
  • Washers
  • Troubleshooting Leaks
  • Pipe and fitting installation

Licensed and Trained Plumbers

Let’s face it, it is expensive to own a home and it can be tempting to attempt the job yourself or hire the cheapest contractor. This may provide comfort and save you money in the short term, but could be costly in the long run. In most cases you get what you pay for. An untrained contractor is usually unaware that they are doing a repair incorrectly or skipping important steps. The same applies if you are doing it yourself. A licensed and trained professional knows every job very well and has continual education. A licensed professional may cost more, but you will have peace of mind that the job was done right.

Licensed plumbing companies possess the proper tools and equipment to do the job. They also know how to use the tools. The best tools are useless if you don’t know how to use them. Most people don’t have the wide variety of tools that are required to properly complete a plumbing repair. Also, some tools and equipment that you may own could be sub-standard. The same can be said for cheap contractors.

Licensed plumbers have a reputation to keep and strive for quality and long term solutions. A bad review by a customer can have a tremendous effect on a company. For example, trained professionals will not only clear your backed up toilet, but they will troubleshoot and fix the cause. If you or an untrained contractor were doing the work, it could take many attempts to find the root cause. In many cases you may have to call a licensed professional to correct the problem. You could have saved money and time by hiring a licensed plumber from the start.

If you are in need of a plumber, don’t hesitate to call us now at 408-295-2182. We offer around the clock service to fit your needs.
