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 Is The Difference Between Commercial AC Contractors and Residential?

While there are some similarities between commercial AC systems and residential, the truth is, there are as many differences.

Commercial AC contractors see a variety of systems and must draw on years of experience to create successful solutions for their clients.

Whereas a residential AC contractor generally sees the same or similar units and can draw from previous experiences to formulate their plan for repair or maintenance.

Working Conditions

Most commercial AC systems are located on the roof of the business so that employees are not interrupted during maintenance or repair.

Depending on how large of a building the system services, it can be across several rooftops.

A commercial AC contractor must be able to navigate the route easily from one system to another and from one rooftop to another.

No matter the weather conditions, whether it’s broiling sun or pouring rain, a commercial AC contractor must show up to do the job. And, most days, will spend all of his time outdoors.

You will find residential AC systems inside the home and usually very easy to access.

The residential contractor may need to wear protective gear while working. However, accessing the system is not typically a challenge.

Business to Business vs. Business to Consumer

Commercial AC contractors work with large businesses on a daily basis.

They interact with building supervisors, property managers, office managers, etc.

Whereas, residential AC contractors interact with homeowners throughout their day.

A family who can’t get their residential AC unit to cool off the house in the middle of summer would call a residential AC contractor.

However, a major corporation who needs maintenance for the LEED-certified installation would call a commercial AC contractor.

Whether you have a commercial or residential AC system, make sure to hire the right professional for the job.

Tips For Keeping Your Residential Air Conditioning Running For A Long Time

With summer around the corner, it won’t be long before you turn on the AC. Heating and cooling costs are a major part of your monthly utility expenses. Improving the efficiency of your AC unit provides two benefits – it lowers your energy bills and keeps your AC running for a long time.

Much like your car, the HVAC unit in your home also needs regular maintenance and tune-ups. A properly maintained air-conditioning unit can last years longer than one which hasn’t been cleaned or repaired in a while. Here are a few tips that can help keep your PC running for a long time:

Replace Air Filters

Dust and debris will clog the filters as you use the AC over time. It blocks air flow, forcing the unit to work harder. A dirty filter will dust to enter the unit and coat inside parts, hindering their ability to function properly. Consult your manual to see how often your filters need replacement.

Clean the AC and Its Surroundings

Apart from replacing the filters, you should clean the unit itself. Make sure to power off the unit before taking it apart to clean. Most HVAC units are located outside the house with ducts or pipes to the inside. Keep the area around the unit clean and remove any leaves, foliage or other debris. Anything that blocks free airflow in and around the unit will lower efficiency. Make sure nothing is blocking vents inside the house as well. Stuffed toys, blankets, and other soft material can cover vents, blocking air flow.

Draw the Shades

Sunlight streaming in through the window on a cold winter day is cozy and comforting. The same sunlight will also heat up your house in summer, meaning the AC will have to power on more frequently to keep the temperature constant. Use curtains, shades, and other screens on windows and glass doors to block sunlight. If your AC unit is not in a shady spot outside, purchase a cover to keep it out of direct sunlight.

Schedule Annual Maintenance by a Professional

In addition to the things you can do yourself, annual maintenance will help you catch problems well in advance. A professional will be able to tell you if certain parts need replacing before they burn out or if something needs lubrication to continue working.

3 Things To Consider When Purchasing A New HVAC Unit

HVAC units play an important role in homes and offices. Most modern systems are responsible for circulating cool or hot air as the need arises, reducing humidity, and maintaining the indoor air quality. It is a key component in maximizing comfort for people living or working in the building.

The average life expectancy for HVAC units is between 10 and 20 years. Most homeowners and building managers will purchase a replacement unit at least once. If you’re in the market for a new HVAC unit, consider the following 3 things before purchase:

Size of the unit

The proper size for the unit depends on many factors including the size of the building, insulation, and even the location. After all, the weather in California will be very different than a summer in Arizona. The size of an AC unit is described in tons and it has nothing to do with the weight of the unit. It is a measurement of its cooling power. As a general rule of thumb, a bigger five ton unit will be more powerful than a 2 ton unit. But that doesn’t mean it is right for your needs.

Efficiency rating

The efficiency of an HVAC unit describes how much cooling power you get for each watt of electricity. Seasonal Energy Efficiency Rating or SEER is the standard in the US and federal regulations require a minimum of SEER 14 for new units. Obviously, units with higher ratings will lower your electricity bills in the long-term. However, very high energy efficient HVAC units will also be more expensive.

Maintenance

Price plays a major role in any purchase decision. HVAC units are no different. But while you might think to compare prices and installation costs, most people overlook long-term maintenance and repairs. An expensive AC unit might require more frequent maintenance and parts may be costly. The warranty on your unit may also be contingent on periodic service visits. Some vendors offer maintenance contracts for your peace of mind. Make sure to ask if your estimate includes service.

Selecting the Right Contractor

Perhaps the most important consideration when purchasing a new HVAC unit is selecting the right contractor. Get at least three bids from different vendors for comparison. Avoid anyone using high-pressure sales tactics as any decent contractor probably has a waiting list of jobs. Half the work is in choosing a good contractor. Ready to buy your new HVAC unit?
