A residential project by Insulation Guru Inc. dba HVAC Guru

Insulation Guru Inc. dba HVAC Guru offers all kinds of HVAC and insulation solutions, from A/C and furnace repair or replacement to insulation, ducting, rodent proofing, air sealing, and vacuum and sanitization. The company provides all of these services to residential and commercial clients throughout Santa Clara County and the Mid-Peninsula. This family-owned company ensures to improve the energy efficiency of houses by keeping them comfortable all year round, and it’s partnered with BayREN to get clients rebates while making their homes efficient.

CEO Lior Zeevi says HVAC Guru’s ability to provide its customers with immediate results has been the key factor in its success. “Most people notice a significant drop in their energy bills right after the work is done,” he adds. “We take pride in providing the best customer service at the most reasonable prices in the market.”

HVAC Guru takes a meticulous approach to quality control on each project, which Mr. Zeevi says is critical for achieving the best possible results. “Nothing matters to us more than happy customers. We go the extra mile to do an extremely good job, as everyone here knows how important it is to consistently meet high performance and quality standards.”

“We want our customers to be happy with every aspect of the job. From the inspection, pricing and service to the post-job care, we ensure it’s all taken care of. We never leave a job site unless the customer is completely satisfied, and we make sure there aren’t any surprises when it comes to the minutest details of any job.”

When making energy efficiency upgrades to your home, consider working with an eco-conscious contractor.
More and more homeowners in the Bay Area are investing in energy efficiency upgrades to reduce their utility bills and carbon footprints. If you’re considering similar upgrades for your home, look for a company that not only knows how to do the work but also has an environmentally-friendly mindset. Not all contractors are ecologically minded in their methodology, which can compromise the very purpose of the project. That’s why it makes sense to hire a company that prioritizes Green building practices.

There are a couple of ways a contractor’s approach to your job can determine the eco-friendliness of the results. One is their choice of materials. “A lot of contractors still use fiberglass insulation, which isn’t very environmentally-friendly,” says Lior Zeevi, president of Insulation Guru Inc. dba HVAC Guru in San Jose. “A better option is Knauf EcoBatt insulation. It’s made of recyclable materials like wool and glass, so it’s much better for the environment.”

Mr. Zeevi says using non-Green products doesn’t just affect the environment—it can also affect the health of everyone who lives in the home. “Spray foam insulation is a popular product, but I don’t like using it because it brings chemicals inside. Styrofoam boards are a good compromise. Since they’re pre-sprayed and cut, most of the chemical vapors are already dissipated before they go into the home.”

Even seemingly minor contractor practices can impact a project’s eco-friendliness, such as the materials used for floor protection. “All the plastic used to cover furniture and floors should be recyclable and placed into specific bags after the job is done,” says Mr. Zeevi. “Even your contract can be Green if the company does everything digitally to avoid unnecessary paper waste.”

Insulation Guru Inc. dba HVAC Guru offers a variety of insulation, weatherization, and ventilation services to residential and commercial clients throughout Santa Clara County and the Mid-Peninsula. In addition to installing spray foam insulation, radiant barriers and HVAC systems that improve the energy efficiency of its customers’ buildings, the family-owned and operated company is qualified to perform specialized work like asbestos removal and attic cleaning.

President Lior Zeevi says HVAC Guru’s ability to provide its customers with immediate results has been a key factor in its success. “Most people notice a difference as soon as we’re done, and when they get their energy bills the following month, they’re even more impressed. It makes us feel good when a client calls to tell us how happy they are with our service.”

HVAC Guru takes a meticulous approach to quality control on each project, which Mr. Zeevi says is crucial for achieving the best possible results. “We go the extra mile to do an extremely good job, even if it’s work that will never be seen, like in an attic or between the walls. Everyone here knows how important it is to consistently meet high performance standards.”

Lior Zeevi: East to West

By James Florence, Diamond Certified Resource Reporter

SAN JOSE — After starting his HVAC career on the East Coast, Lior Zeevi decided to pack up and head west. “I began my HVAC career in 2003 while I was living in Miami, Florida,” he recounts. “What drew me to the industry was an interest in the science of HVAC, particularly air conditioning. Pretty much everyone has air conditioning in Florida, so there was plenty of work, and I ended up opening my own HVAC company. In 2012, I sol...

Call them first. The other ones that came out said it was the heater and it needed to be replaced, but it turned out it was the thermostat that wasn't triggering the heater. He really troubleshot the problem, figured it out and fixed it right away.

They were quick, a one-day turnaround even with COVID. He came out with his booties and mask on and explained everything that he was doing.

I appreciated that when they were here, the crew came up and introduced themselves one by one and it is usually a stranger who works in the house and the person does not introduce themselves. They were polite and great. I have recommended them.

I don't expect this every time, but the agent who set everything up had extra materials and he ended up just putting it on the wall in the attic as a favor. They had enough to go around the whole area and I thought that was very cool and they were down-to-earth and they cared about their customers.

Every department was great, from the financing to meeting the owner. They were knowledgeable and personable. They went above and beyond. They showed me how it was designed in a way that you can redirect where the air flow is going to. The old way was closing the vents in the room that was too hot.
