How Much is Air Conditioner Repair?

Air conditioner repair costs will vary depending on the brand, size, and type of air conditioner. However, it is important to have an experienced HVAC technician come and evaluate your system before deciding whether or not to replace or repair your air conditioner.

So, what’s the problem? Is your air conditioner running but not cooling? Is it not cooling as well as it usually does? Is it making strange noises? These are all questions your technician will want the answers to.

 

Possible Problems With Your Air Conditioner

  • Not feeling as cool as usual. Check the filter and clean it if necessary. Also check around the unit and make sure there is nothing impeding airflow, like plants or curtains. If everything seems clear and you call for a repair, it could cost, according to Home Advisor, as little $200 and as much as $1600 to fix a refrigerant leak and around $200 to recharge the freon.
  • Not turning on, or staying on. If your air conditioner is not turning on or not staying on once it’s turned on, you may have an electrical issue, but you should have a professional check out the condenser, the evaporator unit, and the fan. They may just need to be cleaned, but could need repair. Condenser fan replacement can cost around $500 and an evaporator unit may cost as much as $1000. A circuit board, relays, or other electrical parts could cost as little as $15 or as much as $300.
  • Rattling or other noises coming from the unit? Call a pro and get a tune-up. You might need a few pieces lubed or other parts cleaned and looked at. This will cost in $75 to $150 range according to Home Advisor.
  • Use the 5,000 rule. Many HVAC technicians suggest using the 5,000 rule. Essentially, this means you take the age of the unit and multiply it by the cost of the repair. If the answer is more than $5,000, you should probably replace the unit. For example, if you’re air conditioner is 10 years old and the repair will be $250, you should repair that unit as the answer is only $2,500.

No matter what the problem, make sure you consult with your HVAC technician to make sure you are taking care of the unit properly. If the unit is aging and a repair might be costly, replacing might be your best option. Need help with your repair? Give us a call at (408) 295-2182

 

Does Your Facility Have an Emergency Plan for When Systems Go Down?

Whatever your line of business is, you have a variety of systems that help keep things running smoothly: HVAC for cool air in the summer and heat in the winter, plumbing for the bathrooms, electrical systems for lighting, and perhaps even some audio systems for intercoms or music.

When all of these systems are running smoothly, you don’t generally even think about them. You flip switches, adjust temperatures, flush toilets, and go about your day. But what happens when one or more of these systems go down? What if one system has a minor failure, or what if they all have a catastrophic failure at once?

Do you have an emergency plan for that scenario? You should, because at some point, something will happen.

 

What should your emergency plan contain?

To be fully comprehensive, your emergency plan should be thorough. It should begin with what to do in the event of a minor system failure, detailing the specifics for each system. It should conclude with what to do in the event of catastrophic failure of all systems at once.

It should detail things such as:

  • Whether to send staff home or keep working
  • Who to call for repairs, including names and phone numbers
  • Steps to take to prevent further damage to the system while waiting for repairs
  • If your business has clients or customers, whether to close to the public until repairs are made

There are likely other steps that are specific to your particular company that would also need to be included.

This plan should be in writing, and there should be several copies in several different locations around the property, ensuring that all employees are able to access it and make use of it, in the event of such an emergency.

A critical part of the emergency plan is knowing who to call to get repairs made quickly. You don’t want to have to wait out the weekend, or even a single night, in an emergency.

O.C. McDonald offers emergency service 24 hours a day, 7 days a week. Include our number in your emergency plan, and no matter the time of day or night, our 24-hour live operator can get you set up with one of our experienced technicians to get your system back up and running as quickly as possible.

Should You Clean Your Own Coils or Call a Professional?

Having your HVAC coils cleaned regularly in a year can have a positive effect on the quality of air in your house. Most people seem to not believe in having a professional come and clean the coils, but it is essential to ensure that the cleaning is done by an expert to avoid damage on your system as well as to make sure that the coils are appropriately cleaned. Most specialists advice that you have your HVAC professionally cleaned and maintained at least twice in a year. It is good to have even more cleanings for the condenser coils. Regular maintenance will not only ensure that you have quality air but also promote your system’s efficiency.

Impact of dirty coils on your HVAC system

Having dirty coils can have a direct impact on your energy since the efficiency is affected by cleanliness. Dirty coils will make your system run for extended periods of time to achieve suitable temperature levels. Thus the longer the system operates, the more energy is spent consequently hiking your electricity consumption. The longevity of your system is also affected by dirty coils. Due to the increased running of the system, it becomes more vulnerable to breaking down and therefore continually needing repairs. Eventually, the system will wear out faster compared to a system that is regularly cleaned and maintained professionally

Over the years, HVAC coils cleaning services have grown to be very popular. Any client seeking these services should ensure that they contract a reputable firm to do the cleaning to avoid being scammed.

Here are some useful tips for finding a reputable company:

  • References. Ensure that you get a recommendation from a trusted person to avoid getting low-quality service. You can also check client reviews to confirm whether they were satisfied with the service provider.
  • Certified company. A good cleaning company should have necessary certification by a verified body which sets minimum standards that should be met by the service provider. It is also vital that the client knows the established standards for safe cleaning of their ducts to be in a position to assess the service and also verify that the cleaner follows set guidelines. Always insist for an inspection of the unit before making any payments.
  • Complete service. A reputable and trustworthy company should offer cleaning and maintenance service as a package, not just the cleaning.
  • Ask for quotes. Before settling for a single service provider, ask for estimates from different firms and go for the one that gives you the best deal.

How To Calculate The Load of Your Air Conditioner

Calculating the load required of your facility’s air conditioner is important for maintaining a comfortable and efficient facility. If your HVAC system is too small, it won’t be able to properly circulate cooled air throughout the building. This is probably the more obvious sizing issue, since a building clearly needs enough cooling power to overcome the ambient heat inside.

However, if your air conditioner is too large for your facility, you may experience problems with energy efficiency and the integrity of the system itself. The most efficient air conditioner is one that can continually cool your facility to the right temperature while starting and stopping as few times as possible. Plus, a larger system can cost considerably more to install and maintain.

 

Determining the Right Size for Your Commercial Air Conditioner

There are many calculation methods out there that rely on “rules of thumb” for certain load estimations. These can be misleading, so it is best to avoid them in favor of load calculations that are more appropriate to the actual usage, size, and layout of your facility.

Here are some helpful tips for more accurately calculating your air conditioner load:

  • Take the square footage and ceiling height within your facility into consideration to determine the total volume of air that will need to be cooled.
  • Estimate the number of people who will be working within the facility all day; this can be an average if that number varies over time.
  • Be sure to take note of the number and sizes of any windows and doors that will allow additional heat into your facility.
  • You’ll want to take any other heat sources, such as kitchens, furnaces, or other heat-generating equipment, into account, as well.
  • The local climate can be a major factor in how much cooling power you’ll need, so look for accurate charts that provide air conditioning load information by region.

 

There are many other important factors to consider, as well, including maximum occupancy, safety factors, seasonal weather, and other conditions. You may find it easier to calculate your air conditioner load from this data using one of the many software tools available for creating accurate load estimates.

You can also contact an HVAC specialist to provide you with a professional analysis. Call OC McDonald today at (408) 295-2182 to speak with our experts about your facility’s air conditioning needs.

How Does an Industrial Air Handler Work?

The industrial air handler is an integral part of most industrial HVAC systems. Also known as an air handling unit, this device is responsible for the circulation and regulation of air through the HVAC system. Particularly because of its importance to the overall system, you may be curious about how your HVAC system’s air handler works. Before getting to know the process, it can be helpful for you to learn the terminology and types of air handlers so that you can better understand the unit that you use in your facility.

Your facility’s HVAC system most likely has a large outdoor air handling unit. These are commonly referred to as packaged units (PUs) or, when located on the roof, rooftop units (RTUs). Both of these are also called makeup air units (MAUs), as they only condition air from outside the facility rather than recirculating the air from inside. Air handlers that recirculate indoor air are known as terminal units. These are generally smaller and are only used in localized areas.

The Air Conditioning Process

The easiest way to explore how your air handler works is by examining the route that air takes through the various components of the whole unit. For most larger systems, this process is as follows:

  • Return fans bring air in from the return duct through air filters to prevent dust and other impurities from traveling through the system.
  • Heating and cooling elements, which may involve direct or indirect heat exchange methods, then condition the air to the desired temperature.
  • A humidifier may be present in colder areas to help prevent heating units from drying the air too much during the conditioning process.
  • In temperate climates, air is often moved to a mixing chamber, where return and exhaust air may be mixed to more accurately reach the desired temperature.
  • Supply fans will then blow the air back into the facility through the supply duct.

 

Not all industrial air handlers are made the same. Depending on the size, type, and other factors of your facility’s air handling unit, you may notice different or additional components. You can always talk to an expert if you have additional questions about the inner workings of your industrial air handling unit.

Finding Help For Putting Together a Budget For Your Facility’s HVAC Retrofit

Comprehensive management of equipment and services starts with operational assessment, which provides critical information to help business owners to plan for the future budget. The management looks at the existing equipment plan and financial strategy for the coming years. As such, the management can identify machines that work well and those that are not suitable to use. Thus, by coming up with a detailed report, the operators can get equipment into the proper working condition and provide energy efficiency. Hence, this measure creates a strong foundation for growth and reduces financial risks.

The HVAC equipment used can get utilized in many ways. Here are facility management services that you may put in place to safeguard the material.

  • Working with experienced and dependable technicians to ensure that critical mission machines always operate and serve the intended purpose.
  • Pinpoint incentives to capitalize on returns on capital investment
  • An individual can evaluate a design that best fits the facility and complete probability studies that help in lowering the cost by finding energy-saving programs.

The equipment operational assessment begins with testing and comprehensive analysis of a system. The procedure helps to evaluate typical construction operations and energy used in the building. During the exercise, key pointers get assessed to define baseline performance such as equipment’s ability to perform utility costs and power consumption

 

Controlling the Budget of HVAC Usage

You will have two more factors to prioritize when handling energy projects. Your budget and payback time based on these factors, minimizing HVAC performance time – costs less amount to implement, and has significant investment returns. Clients who enhance HVAC runtime typically manage high savings without applying an expensive retrofit.

The best way to reduce HVAC time is to ensure that you understand when your systems get used. In normal office routine, staffs get at work around 8 am and leave in the evening around 6 pm. However, we still find the system running even after working hours are over. This happens because the HVAC system was built a long time ago and provides inefficiency. Also, you can operate some equipment by using an automatic system that requires no human interference.

The other step involves calculating your saving ability. After identifying HVAC running time, you need to do some calculations. As such, you will discover total saving potential when using the equipment. For example, a facility will require a 200-ton chiller to regulate temperatures of a room. At an electric consumption rate of $0.10/kwh, HVAC costs $51,960 per year to run. If HVAC runtime maintains within working hours, 4hrs can get saved in a day. Therefore, the plan may cost nearly $300, but save the annual recurring cost of $17, 280 per year.

Once you are ready to get started, you can purchase equipment following keenly the delivered capital recommendations to improve cost, save energy, and minimize the risk of equipment debacle. As such, you will form a baseline outlining projected cost, savings, and financial return. Call OC McDonald for an efficient and affordable HVAC equipment installation.
