Comparative Summary

Maintaining customer satisfaction is a crucial aspect of any business, but it’s even more important for HVAC companies that have earned the prestigious Diamond Certified award. For AIS Heating & Air Conditioning, the best way to keep customers satisfied is to eliminate the element of surprise. “When an HVAC company underbids a job, it usually results in unexpected price increases, which is why we provide thorough estimates and firm prices,” explains owner Daniel Sojkic. “Also, we don’t collect payment until the customer is happy with the result. Basically, there are no surprises with us–just guaranteed satisfaction.”

AIS Heating & Air Conditioning has been installing and repairing HVAC systems for residential and commercial clients throughout the Greater Bay Area since 2008. The company also has the in-house capabilities to work on water heaters and air ducts, and its energy audits are designed to help customers improve their indoor comfort and reduce their energy bills.

Unlike HVAC companies that attempt to reduce their operating costs by hiring inexperienced technicians and let the quality of their work suffer as a result, AIS Heating & Air Conditioning only employs experienced professionals who are trained to handle all types of situations. “In addition to being courteous and reliable, our technicians have at least 10 years of experience in the trade,” affirms Mr. Sojkic. “They’re also factory-trained, so they’re very familiar with the products we install.”

To further differentiate itself from its competition, AIS Heating & Air Conditioning provides every job with the hands-on expertise of Mr. Sojkic himself. “I’m a very involved owner, which isn’t common in this industry,” he says. “By personally checking every job, I’m able to ensure high levels of quality control and make sure we’re adhering to our standards for customer service.”

Industry Info

Take simple steps to increase the efficiency of your HVAC system. Even though the Bay Area has a fairly temperate climate, most homeowners still rely on heating and cooling units to regulate the temperature inside their homes. Despite fewer average days of usage than the rest of the United States, that can add up to large heating and cooling bills if your HVAC system isn’t in the best shape. To eliminate waste and increase unit efficiency, consider the following tips:

Have your system serviced annually. Regardless of how often you use your HVAC system, having it serviced by a professional once a year will help ensure ongoing efficiency and prevent unexpected failures.

Clean your air filters once a month. Dirty air filters restrict the flow of air, which can strain your HVAC system and result in higher energy bills.

Keep your air ducts clean. Dust and debris build up in ductwork over time, which can affect your home’s indoor air quality. According to Daniel Sojkic, owner of AIS Heating & Air Conditioning in Fremont, this is especially problematic if you have allergies. “If you don’t clean your ductwork, you’re just circulating moist, dirty air throughout your house and breathing it in,” he explains. “If you have respiratory problems, cleaning or replacing your ductwork can make a big difference.”

You should also have your ducts checked for leaks, which can allow hot or cold air to escape before it arrives in the intended rooms. Windows, doors, and holes around plumbing and wiring may also be air leak culprits.

Keep your heating and cooling registers free from obstructions. Placing furniture and even draperies over the registers can make your HVAC system less efficient. Your rooms may feel colder because the hot air doesn’t circulate as well, and it can cause your system to work harder than necessary.

Replace an old, inefficient HVAC system with a newer, more energy-efficient model. “Industry standards have definitely changed over the past 10 years, especially when it comes to the efficiency of HVAC components,” says Mr. Sojkic. “If your system is more than 10 years old, it’s probably operating at about 70 percent efficiency, depending on the ductwork. If you update to a newer, high-efficiency HVAC system, you’ll easily see a 20 to 30 percent savings.”

DIAMOND CERTIFIED EXPERT CONTRIBUTOR ADVICE & TIPS FROM Daniel Sojkic

Expert CONTRIBUTOR PROFILE
  • Daniel Sojkic is a longtime veteran of the HVAC industry and owner of AIS Heating & Air Conditioning, a Diamond Certified company. He can be reached at (408) 758-5690 or by email.

Daniel Sojkic: A Paternal Partnership

By James Florence, Diamond Certified Resource Reporter

FREMONT — After working with his father throughout his upbringing, Daniel Sojkic left home to pursue a career as an HVAC technician, but as it turns out, that wasn’t the end of their professional partnership. “My father was in construction and I used to work for him during the summer and winter breaks from school,” he remembers. “As I approached high school graduation, the heating and air conditioning industry caught my eye, so I decided to go to technical school. After I completed my HVAC training program, I went to work for a local company, and after gaining a few years’ experience, I started my own business in 2008. Around the same time, my dad was looking to retire from the construction business, so he joined me and we’ve been a solid team ever since.”

Today, as owner of AIS Heating & Air Conditioning, Daniel says his favorite part of his job is saving the day. “I like coming to the rescue when a customer’s heating or air conditioning goes out. No one likes being uncomfortable in their home, so when I’m able to restore that for someone, it always puts a smile on their face.”

Originally from Bosnia, Daniel came to the United States at the age of 11. Today, he lives in Dublin with his wife, Selma, and their daughter, Lana. When asked his favorite part about life in the Bay Area, he cites the pervasive variety. “I really like all the different cultures and ethnicities that converge in the Bay Area. It makes it a very rich and interesting place to live.”

Outside of work, Daniel engages in a variety of pastimes, from outdoor activities to hanging out at home. “I like to get out and explore nature,” he affirms. “Whenever I get the chance, I like to go fishing with my dad or spend a weekend in the mountains with my family. I also like watching the Giants, Warriors and 49ers. Other than that, it’s just spending time with my family and keeping busy around the house.”

In his regard to his professional career, Daniel espouses the importance of integrity. “You have to be honest with your clients and deliver what you promise,” he asserts. “When we meet with a new client, we lay everything out so there are no surprises. If something unexpected does come up, we take full responsibility, because I don’t think it’s fair to make the customer pay extra for something we should’ve caught.”

When asked the first thing he’d do if he were to retire tomorrow, Daniel says he would head to a higher elevation. “I would definitely leave this busy life and move up to the mountains, where I could live at a peaceful, slower pace and enjoy nature.”

Ask Me Anything!

Q: What’s your favorite local restaurant?
A: Claim Jumper in Fremont.

Q: If you could travel anywhere in the world, where would you go?
A: Alaska. I went there last year on a fishing trip and it was awesome, so I plan to return the next chance I get.

Q: What’s the best gift you’ve ever received?
A: My daughter.

Q: What’s your favorite thing to eat for breakfast?
A: Pancakes with eggs and sausage—I can never have enough!

  • How to Choose the Right Air Filter

    FREMONT — When purchasing an air filter for your HVAC system, you have a lot of options to choose from. One important thing to know about is the Minimum Efficiency Reporting Value (MERV) rating scale, which is used to assess filter effectiveness.

    With MERV, filters are rated on a scale of 1 to 20, with 1 being the least effective and 20 being the most effective. For example, a MERV 3 filter can capture 70 to 75 percent of basic airborne particles like pollen, dust mites and pet dander, whereas a MERV 8 filter can capture more than 90 percent. Filters rated MERV 9 to 11 are also able to capture mold spores, smog and odors, and those rated MERV 13 to 16 add smoke, bacteria and allergens to the target list. At the top of the spectrum are MERV 20 filters, which can filter down to the size of airborne viruses.

    While a higher MERV rating means greater effectiveness, it also means a greater expense, which is why you have to weigh cost versus benefits when purchasing one for your home. Keep in mind that anything higher than MERV 16 is excessive in a residential setting, as these are designed for use in highly sensitive industrial or laboratory settings. You should also make sure to get a filter that’s appropriate for your HVAC system, as an overly restrictive filter can inhibit proper airflow, which can cause the system to malfunction.

    To ensure a minimum baseline of performance, it’s best to avoid any air filter rated below MERV 5. MERV 9 filters, which are designated as “Better Residential,” are a good choice, but if you’re extra concerned about the quality of your indoor air, consider upgrading to a MERV 13 filter, which is designated as “Superior Residential.”

  • Video: Furnace Filter Options

    Complete Video Transcription:

    FREMONT — Host, Sarah Rutan: When it comes to choosing a furnace filter, there are more options available than you might realize. Today we’re in Fremont with Diamond Certified Expert Contributor Daniel Sojkic of AIS Heating & Air Conditioning to learn more.

    Diamond Certified Expert Contributor, Daniel Sojkic: As you can see, there are many different air filters that you can choose for your home needs. This is one of the basic air filters out there in the market that you can grab from any local hardware stores. As you can see, this filter, you can see right through it. So it does not collect much of the dust – anything that doesn’t get collected by this air filter, you are inhaling that dust.

    This is a grade higher air filter, which has a MERV-8 rating – so it’s a really decent filter. It costs few more dollars than a basic air filter. But it’s much better air filter. Next filter that we have, it’s called electro-static air filter, this a really good filter for about two years. Take it out every two to three months, just hose it off, let it dry, put it back, and you’re good for next three months.

    This is one of my favorite filters. Has a MERV-11 rating on it. This filter – it’s included in all the wire installations that we do, and this is filter is good up to a year depending on the usage of the system. This is one of my favorite filters. This right here, it’s Bryant-perfect air. This has a MERV-15 rating. It’s great for allergies, dust, pollen, any bacteria in the air. This is the filter to go with. The cartridge in here – it’s good up to a year depending on the usage.
