What Are The Symptoms Of A Bad AC Compressor?

A bad AC compressor can turn a nice day into an overheated nightmare. Your compressor is one of the most important parts of your cooling system and a common point of failure when things go wrong. Below are just a few symptoms that could indicate that your system is failing.

Signs of a Failing Compressor

In most cases, the first sign that you’ve got a bad compressor will be the fact that your system is blowing warm air. There are other causes, of course, but systems that are on the verge of compressor failure often start to blow warm air instead of cooling down your home. If you notice a sudden change from cold air to warm, there’s a very good chance that you’ll be dealing with a failed compressor in the near future.

You might also notice some power consumption problems if your compressor is in bad shape. If your circuit breaker is frequently tripped when your air conditioning unit is turned on, there’s a very good chance that your compressor is overheating and drawing in too much power. It’s very important that you don’t keep resetting your circuit breaker in this case – if your compressor stays in the state, you might be looking at a catastrophic failure.

Other signs are a little more dramatic. If you notice that your condensing unit is violently shaking every time that you turn on your air conditioning, there’s a chance that your compressor is having trouble turning on. Likewise, a nosy condensing unit can often be a sign that a compressor is starting to struggle. If you’re dealing with either of those signs, there’s a good chance that you’ll need someone to look at your air conditioning unit quickly.

The most dramatic sign of compressor failure, though, is that the compressor stops working altogether. There’s not a problem with the power supply and your indoor fan will keep blowing, but the compressor simply isn’t making any noise at all. If attempts to lower the thermostat aren’t met with any success, you’re probably looking at a compressor that has already failed.

If you think that your compressor isn’t in good shape, it’s better to call for AC repair sooner rather than later. As you can see from the information above, some of the problems that indicate a bad compressor can actually be quite dangerous. If you want to make sure you have a cool home and a working AC compressor, don’t delay – call O.C. McDonald at 408-295-2182 to get the help you need today.

How Often Should You Be Doing Air Duct Cleaning in Your Home?

Air duct provides a fundamental function in most homes. It is part of the HVAC system that provides conditioned air inside the house allowing a consistent comfort no matter the season. In fact, air moves through the ducts to allow sufficient circulation of air in each room. It is the same air that everyone in the house breaths and if not controlled can cause respiratory issues and other health problems. Therefore, it is important to ensure that the air supply inside the house is as clean as possible. However, most people do not consider the important role air duct plays in the circulation of air. Dirty air duct can considerably compromise the quality of air inside the living space. Air ducts cleaning is, therefore, a paramount task that every family should consider.

Air duct cleaning refers to the removal of contamination in the duct system. The duct system includes the supply and returns air ducts, registers, and diffusers. Experts agree that cleaning the ducts has direct and significant health benefits. Cleaning the accessible parts, for example, the return and supply duct does not solve the problem entirely. It is therefore recommended to hire professionals that are approved by the National Air Ducts Cleaners Association (NADCA).

How often should the air ducts be cleaned?

According to NADCA, air ducts should be cleaned as often as three to five years. This is because most people spend most of their time indoors. Additionally, a study by the American College of Allergists reveals that half of the ailments are caused or aggravated by impure and inadequate indoor air circulation. On the other hand, American Lung Association indicates that air pollution contributes to lung diseases, which is a major leading cause of death in the US. Furthermore, the US Environmental Protection Agency indicates that poor indoor air quality is among major environmental risks to public health.

Benefits Of Cleaning The Air Ducts

Cleaner living environment – Dirty air ducts can cause dust to distribute throughout the living space. However, a thoroughly cleaned air duct helps to maintain hygiene and reduces the amount of interior cleaning and dusting.

Reduced allergens and irritants – Apart from dust, dirty air ducts can contain harmful contaminants like bacteria, pollen etc. These contaminants can be very sensitive to people who suffer from allergies and other respiratory conditions. Frequent air duct cleaning eliminates contaminants promoting a healthier living environment

Improves air supply and efficiency – Dirty air ducts restrict the efficient flow of air through the HVAC system. Conversely, a cleaner duct promotes quality air flow.

When Your Plumbing Needs Attention Here’s What You Need to Know About Replacing or Repairing Common Fixtures

Overall, three factors need to be looked at when you’re wondering whether to replace or repair a plumbing item.

To begin, look at how old the item is; usually, if we see that the water heater in the house is averaging an age of 8 to 10 years, we would assess that (besides other aspects) to reach the recommendation of probably replacing the fixture, because it’s most likely past its prime. Age is a significant part of ensuring that you’re sinking your hard earned dough into something that’ll keep costing you in the future.

Additionally, you’ll want to think about what it costs to repair the fixture. There are quick fixes that you can apply to an issue, but completely restoring fixtures is sometimes costly as opposed to the price of just placing in a new item.

Comparing the advantages of buying new items with the price of repairing the current object is a smart thing to do. Some of the time it may be a no-brainer to repair a fixture rather than just replacing it altogether. But over time, if you have to do that repair numerous times down the road, that’ll add up fast. But, many common problems have common solutions.

Running Toilet

If you’re fed up with wiggling the handle to get your toilet working after flushing, it could be due for a replacement of its inner functions. Toilets generally run if the flapper valve that moves the water from the tank to the bowl no longer fits, the fill tube gets slack or the float is improperly balanced. Toilet kits fix the majority of models and are easy to replace.

Leaky Pipes

Whether your routine inspection discloses how a puddle is forming under a pipe or you get a rude awakening as you touch under the sink, leaks are unwelcomed expenses. The leaks are going to occur usually from the joints, indicating why commercial joint fitting compounds and fillers take up as much shelf space as the door in hardware stores. These solutions offer temporary fixes though; a sufficient plumbing repair can involve replacing a stretch of fitting or the pipe.

Entirely replacing your leaky U-joint below the sink isn’t a complicated repair, it’s a dirty one. That’s why you might want to find a professional who can do it for you to avoid the time it takes to clean-up. Until you can get a plumber to the leak, you can apply a compression clamp with leak tape or a rubber sheet.

When It’s Good to Call a Professional Plumber

Some problems are too hazardous or intricate to handle by yourself. Choose a certified plumber for the integrity of your home and peace of mind. For any questions, or you need to schedule an appointment for maintenance or emergency repairs, call us at 408-295-2182

What To Do When You Need Emergency Air Conditioner Repair

Air conditioning at the workplace must work perfectly if you want your staff to work without disruption. Sometimes an emergency might occur. Some of these situations are easy to spot, while others can be complex. Some of them you can fix, but others require tools and skills that only experts have.

If your system manifests any of the following complications, you need an emergency repair.

  • Icy evaporator/condenser coils
  • A plastic smell on your wiring
  • Uneven conditioning/cooling
  • Unusual noises

For most people, when they encounter some of these problems, they tend to ignore them especially if the system is still working. If you do so, you risk further damage, which can lead to expensive repair and replacements. Do not ignore even the slightest of them; have it fixed immediately.

If your system has any of the complications above, do the following:

Check if the system is powered correctly

It is simple; if your power supply is not adequate, your system will not work optimally. Power outages, intermittent capacity, and low voltage can cause system failure. You have to check your power source to be sure that your system has an emergency. Tripped circuits and breakers, powered off switches, and destroyed fuses can give you a false alarm that your system is not working.

Check your thermostat settings

Your system is not cooling because it is probably not set to cool the office. Always check your system settings before calling in for an emergency. Ensure that your thermostat temperatures are below the room temperature if you want to cool a room.

Check your filters

Clogged or dirty filters can be the cause of your air conditioning problems. If you know how to clean reusable air filters, you can go ahead and do that. If you are not sure, call in a trained expert to help you with that. You can also replace it with a new one as you wait for the expert.

Call a professional

Once you have checked the power, settings, and filters, your system should be working efficiently. If it does not, it means it needs an emergency intervention. Call in trained HVAC experts within your location.

An experienced and professional company will troubleshoot the problem and fix it. If your system has vulnerabilities, it will also advise you accordingly.

5 Things You Can Do to Avoid Calling Any AC Repair Companies

If your company maintains facilities in the San Jose or Bay Area, you certainly appreciate the challenges of depending upon HVAC firms to provide rapid service on short notice following an unexpected breakdown. By far the best strategy involves avoiding the need to request skilled cooling system services. Taking five precautionary measures helps ensure you encounter minimal costly “down time” as a result of a malfunctioning HVAC system:

First, you’ll want to familiarize yourself with services available from one of the leading industrial, commercial and institutional HVAC design and rebuilding mechanical contractors in this area. O.C. McDonald possesses extensive experience assisting local businesses. We specialize in process pipe fitting for HVAC systems. By adding our name to your emergency contact lists, you’ll always obtain access to well-qualified specialists in this field on a 24/7 basis.

Next, you should consider asking us to customize a cooling system for your plant. Whether you maintain an educational institution or a high-tech manufacturing venture, we’ll help design and construct a tailored AC system with the capabilities to meet the needs of your business mission. This step eliminates problems arising from a “one size fits all” consumer-based model for HVAC services. We offer turnkey development and installation assistance.

Important Additional Measures

Three further measures help you keep your system running, avoiding the need to contact a repair service on short notice. Most importantly, consider asking O.C. McDonald to provide regular monthly or quarterly inspections and maintenance services for the system we design and install. This regular consultation helps us detect any developing problems at an early stage. It helps prevent sudden, catastrophic cooling system breakdowns.

Yet another useful protocol involves carefully monitoring your system’s performance. If you anticipate a higher than normal demand for HVAC services during a summer heat wave, for instance, implementing this action helps you remain alert to the condition of your equipment. If this machinery appears likely to exceed its normal operational parameters, you may want to schedule an extra, early inspection and maintenance visit from our service technicians.

Finally, encourage your in-house plant maintenance and HVAC personnel (if any) to consult with us periodically about the most important available upgrades for your cooling system. No enterprise remains completely static. We’ll help ensure your cooling and heating systems evolves efficiently and cost-effectively!

What’s The Difference Between Residential Air Conditioning Companies And Commercial Ones?

There are essentially two types of HVAC companies, residential and commercial and many times a combination of the two. The chief difference between the two is one is only licensed to do residential and commercial companies are sometimes licensed to do both. However, most commercial HVAC companies concentrate on commercial projects and leave the residential to others. Some companies however are very good at doing both! These companies have stood the test of time and have endured both good times and bad to get to where they are today.

The chief differences between the two . . .

  • Residential Characteristics – specializing in home air conditioning and heating; Usually can respond after hours or in emergency situations; performs annual start-up and preventive maintenance, repair and installation of residential HVAC equipment; technicians are usually licensed by the state they work in to do only residential work, but not always. There are some residential HVAC companies that are fly-by-night and should be avoided; Reputable companies are licensed, bonded and insured so be sure to review these to ensure they are all current. Usually a permit is required for new installations. The residential HVAC company should be very familiar with the permitting process.
  • Commercial Characteristics – specializing in commercial HVAC applications such as HVAC for retail buildings, office buildings and other non-residential applications; technicians are usually of the Journeymen experience level and are licensed by the state they work in; Commercial HVAC companies are required to be licensed, bonded and insured. Commercial work is generally done under the existing building permit as “maintenance” however most new installations or system renovations are required to be permitted and inspected.

Talking directly about the combination companies referred to earlier, generally these companies have been around for many years and have proven themselves. These companies have resident experts that have performed the various types of HVAC work for many years in the local area. Most of these experts are owners or at least co-owner of the company. Some companies even have specific departments for residential, commercial and new construction. This keeps the focus of the work where it should be, on the customer’s needs.

Can Custom Duct Work Be Done To Fit My Building?

The building that your business occupies for years can prove to your customers that you are here to stay. But what happens when you experience growing pains? Many times a building simply no longer provides what you need. So, now you have some decisions to make. In most cases, a new building is out of the question so you must look deeply into what your needs actually are and compare this list to the existing space and what it could provide in a new configuration.

  • Historically, office space is easy to deal with.
  • However, the comfort level, efficiency and safety of the newly configured space all need to be addressed. When a building is initially designed, the systems tend to be somewhat over-engineered allowing for future expansion and unfortunately a bit less efficiency.
  • In the case of the HVAC system, Rooftop units are easily upgraded to proved additional heating and cooling.
  • In the case of larger buildings with mechanical rooms designated for HVAC equipment, the room and equipment can be reconfigured to meet current needs. Air handling units, pumps and other system components could be upgraded, many times using the existing units by simply increasing capacity. A larger fan motor can provide additional air moving capacity. A pump with a larger motor or even just a differently designed impeller can provide additional water for heating and cooling.

Getting the increased air flow to where you need it!

Upgrading the mechanical room or Rooftop units is all well and good but what about the requirements of the newly reconfigured space? You can assume that the existing ductwork will not be sufficient to handle the new air delivery requirements. Most times, these air delivery requirements are dictated by law for various industries. For example, a laboratory has very different requirements from an office space.

Your HVAC system helps keep the air clean and tempered in your work environment. By law, there are different requirements for “number of air changes per minute” in a space. This keeps the air fresher by venting a portion of the air to atmosphere and replacing it with fresh air.

Custom duct work is a large part of the building renovation process. If you find yourself in this situation kindly give us a call and we will help you through the process. Ready to get started? Call us today at 408-295-2182

How To Verify A Legitimate Contractor In California

If you have spent any length of time in California, then chances are you will deal with an HVAC contractor sooner or later. Like everyone else, you are probably very concerned about avoiding getting scammed or ripped off. How do you verify a California contractor? That will be the scope of this article, and there are two good ways and one great way. Consider the following options:

•Word of mouth
•Internet reviews
•Licensure checking

Word of Mouth

Word of mouth would be one okay way to verify a legitimate contractor. However, it definitely has its limitations. Even if you know someone who has used the contractor in the past, the pool of people you can sample from is limited to how many you might know. Frankly, this method would probably only work effectively within a smaller community.

Internet Reviews

Internet reviews are, in some cases, a more effective way to verify a HVAC contractor. However, even and internet reviews, there is the potential for a smaller sample size. There are only a certain number of people that might take the trouble to go onto the website to leave a review. So, even though it might be better then word-of-mouth, the sample size might still be fairly low.

Licensure checks

Calling up the license your agency might be the best way to legitimately verify an HVAC contractor in California. This is because it is one great way to determine if there have been any complaints lodged against the individual, and to note the severity of any complaints that are present. The state license your boards keep meticulous records regarding each and every incident that one of their contractors is involved in. This means that if you call them you can have peace of mind that they do quality work if the licensure board reports no incidents against them.

Other Considerations

Besides the three mentioned above, there are other considerations that could come into play. The length of time the contractor has been in business could play a definite role. In that case, a combination of all three might be the best approach.

What All Can Custom Sheet Metal Be Used For?

When it comes to architectural projects, one of the most commonly used materials is custom sheet metal. Sheet metal is a component that is easily fabricated and adapted to countless uses both in residential and commercial construction projects. From the mailboxes in a residential neighborhood to the air ducts in a commercially designed building, the presence and versatility of custom sheet metal is undeniable when it comes to today’s tried and true construction practices.

The residential and commercial uses of sheet metal have large areas of overlap, including the aforementioned air conditioning ducts and cooling systems as well as lighting fixtures (both for exclusively functional purposes but also custom aesthetic fixtures too). However, lets dive a little deeper into the applications of sheet metal within the home.

Residential Applications of Sheet Metal

Sheet metal can be hiding many places you wouldn’t normally expect to find it within your home, which means it’s doing the job it’s designed for: remaining functional while also blending in with the look and feel you’ve strived to achieve within your home. From custom flooring or siding to backsplash in your kitchen or bathroom, sheet metal can be tastefully implemented anywhere.

The kitchen can be one of the most common places for sheet metal because it can easily be used for stovepipes or stove hoods, or it can even be used to make food vats or bins, but that’s more often seen within commercial applications such as in a restaurant or cafeteria setting.

When it comes to other outdoor residential uses, sheet metal is often used to construct various types of fencing enclosures as well. The uses for sheet metal really are boundless and can include:

  • Awnings and canopies
  • Gutters and other roof draining equipment
  • Coal chutes
  • Guardrails

Sheet metal can be manufactured in either flat pieces or coils depending on the fabrication process and the needs of the client. While the material has increased in popularity in architecture and construction projects in recent years, it has also seen widespread use in electronic fields and in fields such as the manufacture of military-grade weapons and equipment.

Whether you’re in the market for something simple like a custom sheet metal sign for your business in need of a more hefty air conditioning system makeover, don’t hesitate to call us at (408) 295-2182 to chat about your options today!
