Insulation Gurus
According to the U.S. Department of Energy, 42% of a homeowner's utility bill is spent on heating and cooling costs. When a home is poorly insulated, 42% can rise infinitely. Your HVAC system will work overtime to cool or heat your home only to have the energy escape through your attic, walls, and crawlspace.

Proper insulation provides resistance to heat flow and lowers your heating and cooling costs by an average of 20%! Bottom line: You can cause severe damage to your bank account if your home lacks the proper amount of insulation or if it is installed incorrectly! Call the Gurus to make your home efficient.

Insulation Gurus aim to improve energy efficiency, comfort, safety and interior air quality for residential homes and commercial buildings. With 15 years of experience under his belt, the Guru has mastered the art of insulating residential and commercial buildings. The Guru began his journey in Florida and eventually moved to California where he founded Insulation Guru, Inc in the summer of 2016.
Services
Before you add or replace your insulation, you should make sure that your home is properly air sealed. Air leakage occurs when outside air enters and conditioned air leaves your house uncontrollably through cracks and openings in your attic, walls, and crawlspace. Another thing to note is that leakage also occurs with your duct system.
Installing attic insulation is a task that you should leave for professionals like us. Your attic may have certain conditions, including but not limited to rotting attic rafters, minimal attic ventilation, rodent infestation, and hazardous material, making the job dangerous for yourself.
Approximately 15% of your home's energy escapes through the floors and out of your crawlspace or basement. Crawlspaces and basements are overlooked the most when it comes to home improvement. Heat is lost in all directions- not just up. Foundation materials like concrete and stone have almost no insulating value and will easily allow a significant loss of energy.
The first thing that must be considered is the proper distribution of air throughout your home so that comfort can be maintained and your HVAC unit is as economical as possible.

When installing or retrofitting ducts, they should be properly sealed, have the right combination of supply and return flow, be insulated against the elements, be sized correctly, and have the capability to provide the amount of air that is necessary to keep the temperature throughout your home at an optimal setting.
Removing and replacing old or damaged insulation will dramatically improve indoor air quality and make you home more energy efficient. The efficiency of your insulation will decline naturally over time as it ages and is exposed to outside factors such as rodents. Feces, urine, and rotten flesh from dead animals spoils the insulation and brings about unpleasant odors.

Simon came out the house today to do an evaluation on how to improve the temperature differences between our bedrooms. He was able to make some quick changes to our HVAC ducting that had an immediate impact. Simon was friendly and knowledgeable. I highly recommend this company.

Please see my review under their DBA HVAC Gurus.

This company works hard to get the deal and then is too busy to honor their warranty.

I wish I chose another contractor

They scheduled and cancelled my appointment 4 different times. This is one of the most unprofessional companies I've ever talked to. Stay away if you value your time & energy.

Just had Insulation Gurus put new blown-in cellulose insulation in my attic (all the old insulation had been removed months earlier by another company so new HVAC ducting could be installed up there). Jacob was very helpful and responsive in preparing the quote and answering questions. And Brian and his crew did a friendly thorough job with the actual insulation (vacuuming beforehand, air-sealing cracks, baffling soffit vents, and getting the new cellulose layer nice & even).

The team that came to our place for insulation installation were nice. There were members who worked quickly to get it completed fast. However, there were a lot of miscommunication between the first person who gave the quote/crew/management. I was told a lot of extras to be done, which were not discussed with the crew members, there was definitely overselling to earn my business. I was also supposed to get the HVAC service the same day, but they never showed up and this was not communicated until the day of the insulation work. There was also some drama with the payment etc. Overall, I recommend

Decided to not move forward with this company due to their ambiguous pricing and methods of determining a quote. I found the company through an ad that offered a 10 % off coupon for their services. After my husband and I presented the coupon, they responded with something along the lines of "that ad has been running since February" and "the prices were already discounted". I mean, maybe it's me, but why does it matter if the coupon has been valid since February? There wasn't an expiration date on it or terms of service that made the coupon ineligible to use so I don

We needed insulation for our garage and I found Insulation Guru on Yelp because of many positive reviews. They responded quickly and Jacob came to our house to provide a free consultation within a few days. The price is very reasonable and moreover the work done is excellent. My garage used to be an oven in the summer (90+F) now it is nice (ambjent). Finally I can enjoy my garage.. Definitely considering insulating our attic with Insulation Guru in the near future!

I needed some basic insulation for turning a bedroom into more of a soundproofed recording studio. They got the job done quick efficiently and cleanly. The name of the worker that worked on my room was either Carmelo or Marcelo ... I am sorry to have forgotten his name but would like to add that he (and his partner Santos) were professional, friendly and respectful. Thank you, Gurus!

They installed a mini split AC for us. Works great, keeps its half of the house cool easily. It had a malfunction in its first year and they came and fixed it under warranty.

The installation pros we've seen are super friendly and efficient. Definitely recommend.

Great company to work with!
Excellent customer service.
At first, we had Luther to stop by our place for evaluation and quotation. He is very knowledgeable and patient. He explained all options we had.
Jose and Leo came out and did a great job to complete the entire three days work, from demolition to installation. We now have a brand new high efficiency heating system.
Later on, they also did fine tuning for the furnace and ducts to optimize the efficiency and to reduce any possible noise, thank you again to Jose and Gerrit!

In the process of taking quotes from 3 vendors I asked these guys to give me a quote as well. They said they do not take care of the rebates - it was going to be the customer's job to do that. fair enough. Then they give me a quote that is double of their nearest competitor!!!
I said Thanks but no thanks and went with another insulator who was cheaper and also filed for the rebate on my behalf.

The Gurus installed a Cassette Mini Split HVAC at my home. Simon was very knowledgeable and professional with the Job estimate & planning. He always kept in touch and gave an outstanding price. The installation crew was on time and finished the work within one day, gracefully overcoming all hurdles and obstacles. Overall it was a great experience and we'll definitely contact them again in future for any HVAC or insulation work.

Our experience for getting a quote was not great. Got handwritten total cost numbers during scheduled visit on a paper, no email quote. Even after reaching to front office, no email quote is received.

We don't have any experience on their service yet, but our experience for getting quote is not very pleasant.

======== Post clarifications updated above and added below =====
The gentleman who wrote the quote reached out to us. He explained to us that the front office noted the wrong email address and after correction, we immediately received our quote. So, I am giving one more star. I will

We've had a few interactions with Insulation Gurus now, and everything was efficient from the first phone call to the inspection/quote to the actual implementation of the work. We moved into an older home that had old / sparse insulation, old ducts, and a lot of leftover rodent droppings.

The person who actually came to do the work was Carmelo. He was professional and courteous. Especially when dealing with attic materials and rodents, it was important to us that they kept the rest of the house sealed off and clean, which they did. He did a thorough job with the attic and went above and

From initial email sent for some information all the way though to job completion, I was completely satisfied. Office staff was polite and courteous; quick to respond to my initial email (within 24hrs). Ron was the consultant that came out to educate my wife and I and bid the job. While in our home, Ron identified some issues with our HVAC and literally fixed them on the spot (this was all prior to talking about insulation). No pressure. GREAT price. Bid accepted onsite.

Work began a few days later. Carmelo was the lead on the crew. I was thoroughly impressed by how he kept me informed along

Our rental property furnace was not working and only blew ambient air. Simon with Insulation Gurus came out and diagnose the problem and fixed it within 2 hours.

They were quick to respond, professional and price accordingly.

Tip: When the tech comes out, make sure you get a price before they start the fix. This way, there is no surprise as to how much the repairs would be.

I needed an inspection for my ancient wall heater. Simon was on time and efficient. He provided useful information about my system and made constructive suggestions regarding its maintenance..

The price for the visit was reasonable and it focused on inspecting the existing system. It did not focus heavily on cross selling or upselling which was my experience with other HVAC vendors.
