What are the steps for HVAC installation?

Nothing is more important than the quality of your new HVAC system installation. It drives the longevity of your equipment, your indoor comfort and your energy bills. Before you sign a contract with an HVAC company, be sure that they follow the best industry practices.

Sizing

Beware of the contractor who goes by the size of your existing HVAC system for your replacement. A reputable contractor will conduct a load calculation using Manual J software by assessing the following factors before suggesting a system size:

• Cubic footage
• Attic and wall insulation levels
• Size, quality and placement of windows
• Floor plan design
• Air infiltration rates
• Landscaping factors
• Family size and ages
• Preferred indoor temperatures
• Number and use of appliances that create heat indoors

Each of these conditions affects how energy efficient your home is. Once the technician enters the data, the software returns recommendations about the size your system should be.

An HVAC system that’s too large or small won’t run as efficiently as one that’s the optimal size. If you install one that’s too large, it will run in short cycles that lower your comfort, leave humidity behind in the summer, drive up your energy bills, and need more repairs. A system that’s too small probably won’t be able to keep you as comfortable during weather extremes.

Duct Work Inspection

A new HVAC installation requires a thorough duct work inspection. If there are leaks, broken segments, or other signs of duct work failure, the contractor needs to replace it. It should also be sized properly by using Manual D to make sure that it has the right capacity for the new HVAC system.

Leaking duct work reduces the energy efficiency of the new HVAC system and if it’s too small, they will be noisy when the HVAC system runs. If the ducts are too large, there won’t be enough air pressure coming from the air handler to deliver the air to each room.

Exploring the Options

Once you’ve gone through the basics, review what you want from your new HVAC system with the expert. There are a number of system options that enhance comfort and energy efficiency like variable-speed operations and smart system controls.

What To Look For In a New Construction Contractor

It’s a beautiful day and as you settle into your morning routine at the office, sipping on your second cup of java your office line rings. A pipe has burst in the lobby restroom and water is everywhere. The company’s largest client is coming by for a lunch presentation and time is of the essence. If you’re prepared, you’ll have your construction contractor on speed dial. If not, you’re going to have to move quickly to find a reliable and reputable firm that can handle the situation stat. Don’t put yourself or your business in that situation.

Identifying a new construction contractor doesn’t need to be daunting. Hopefully, you’ve not waited for a plumbing or HVAC crisis to look for a new construction company to work with. If you’re a large corporation or small to medium sized business, the same evaluation strategy applies.

Key Qualities to Look for in a New Construction Contractor

Company history. The length of time a company has been in business says a lot. There are construction contractors that come and go. Look for a business that has a solid history. Factor in how many years they’ve been in business and if they’re family owned, even better. A construction contracting company that has generations of experts behind it is a find.
Reputation. If the company has been in business for years, they must be doing something right. Take a look at their reputation. What are customers saying about their work? Do they get the job done in a professional manner? Are they dependable? If they’re keeping their clients happy and expanding their business, give them another positive check on your evaluation list.
Expertise. Your construction contractor should be well-versed in the basic mechanics of everything from piping, gas fittings, new and old construction, to HVAC and more. They should be able to handle it all. You want to use an expert firm. One that keeps up with proper licensing and training for all crew members and leads their industry when it comes to cutting edge technology.
Safety. Safety first should go without saying, but this needs to be taken into consideration. You want a new construction contractor that put this as a top responsibility.

Can You Just Replace an AC Compressor Instead of The Whole Thing?

The HVAC system of your business is a critical component of your building and its function is vital to the overall health and ability of your business to function, whether you are running a small office building or a large industrial complex. Keeping the air temperatures regulated and airflow moving steadily can impact your bottom line.

Often, as the HVAC unit or units for your business age, they show symptoms of failure before complete breakdown. Symptoms such as failure to produce cool air can be tracked to a number of smaller issues, such as a coolant leak or a line blockage, but a thorough inspection by an HVAC professional may also uncover major issues such as a compressor failure.

In the case of a compressor failure, you need to decide whether your business will best be served by replacing the compressor or by replacing the entire AC unit.

Replace the Compressor or Replace the AC Unit?

  • Consider replacing just the compressor if the existing AC unit and component parts are still under warranty. In this instance, the new compressor should not cost you anything but you will still need to pay for the labor to do the job. Make sure to get a quote on the labor, time, and materials as replacing a compressor can be a challenging and time-intensive job.
  • Consider replacing the AC unit if the system is past warranty. While you could opt for replacing just the compressor in this case, bear in mind that the cost of a new compressor, as well as the cost for labor and materials, may be close in range to the cost of installing a new AC unit.
  • Consider as well that a new compressor may only come with a limited warranty, up to
    1-2 years, and that you may find yourself back in the same situation in a short amount of time, facing the same issue without the benefit and security of a warranty to offset the cost.

Dealing with the advanced and technical needs of your HVAC system can be daunting, especially if your business is impacted by changes in temperature and loss of cooling due to AC problems. Let us solve your AC problems so you can focus on what matters most: the success of your business. We can help, call now 408-295-2182

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.

How to Choose a Commercial HVAC Company for Your Educational Facility in the Bay Area

The heating and cooling system (HVAC) is among the most complex yet significant components of any building. Any malfunction and lack of proper maintenance can render your building uncomfortable and uninhabitable, particularly in the Bay Area. It is important that the HVAC company you hire for repair, maintenance or replacement do a good job and restore things to normal.

Four HVAC Things to Consider

Here are a few things you need to consider to get the right HVAC company for your educational facility in the Bay Area.

  • Consider Licensure and Certification. Any company that offers HVAC repair, replacement or maintenance services in the Bay Area must have a valid operating license from the State of California. A license shows that the company has met all the requirements and has proved beyond any reasonable doubts that they have the capacity to deliver high-quality services. Ask the HVAC contractor to produce copies of their current license as well as certification.
  • Determine If They Are Insured. Accidents often occur. One of the HVAC workers might trip and injure himself, or equipment might fall on a fragile item and cause a lot of damage. You need to be sure you won’t be held financially responsible if an accident occurs. Make sure the HVAC company has an insurance policy that covers against any injury or property damage that might occur.
  • Research the Company. You need to research the company online to determine whether they have a decent rating and fewer customer complaints. You can visit the Better Business Bureau to see what people say about them and how they are rated. A good company should have a rating not less than 4 stars and fewer negative reviews.
  • Ask for References. Ask the company to give you a list of five previous clients. Reach out to each one them and ask them to give you an honest review about their experience with the company. Let them tell you how the company handled their projects and whether they were satisfied with the final outcome. Also, let them tell you if the company answered their questions to their satisfaction.

The Basics of Heating and Cooling for Commercial and Industrial Buildings

MAINTAINING PROPER COMMERCIAL OR INDUSTRIAL BUILDING TEMPERATURE

The importance of maintaining a comfortable atmosphere in a commercial or industrial business cannot be overemphasized. For a business, having customers comfortable is of prime importance. In an industrial building providing workers and visitors with a well-regulated temperature is of prime importance for an enjoyable work place.

Government studies have shown that commercial air conditioners increased employees’ productivity in offices and factories at least 25 percent. It also reduced absenteeism. This results in fewer problems in the workplace and fewer problems for management.

Customers entering a business need a comfortable atmosphere if they are to shop without the discomfort of a cold or hot temperature. Businesses have found that proper air conditioning solves the problem and results in an increase in sales.

This means that your HVAC must be working well and providing the heat or cool air that is required. Having the proper unit and providing proper maintenance will fill this requirement.

FINDING THE RIGHT COMPANY FOR INSTALLATION

Installation of a commercial HVAC unit often requires custom sheet metal fabrication as well as a specific design for building adaptation. This means contacting a reliable company that has a proven track record in this field. They will have an expert come to your location, take measurements and discuss your particular needs. He will then present an estimate of the work to be done. As a rule, there is no charge for this service.

Naturally, on a large industrial or commercial building, drawings will have to be made to provide an outline of the installation. This should be presented for your approval. The location of air ducts is especially important. These are quite large and in many cases must be concealed.

There are many excellent HVAC models that are especially designed for commercial installation. A few of these are Carrier, Trane, Rheem, Lennox, York, Amana and others. Choosing the right size is especially important if the desired temperature is to be maintained. After determining your need, the air conditioning company will make a recommendation regarding which unit is best for your needs.

Having an experienced company taking care of your heating and cooling system on a regular basis saves a great deal of money in the long run. A regular maintenance program, by experts, makes it easy to quickly spot, and correct, any defects that can develop into major problems over time. This will save you money as well as the headache of a broken down HVAC system.
