    Insulation and attic fan.

    Attic Masters insulated our attic yesterday. Our home is 70 years old, and still had the original sawdust insulation installed. Attic Masters' crew came and removed all the old insulation along with assorted debris from the past decades, sanitized the space, air sealed all the cracks, did some rodent-proofing, and installed new insulation. We got several quotes when planning this work, and chose this company because the gentleman that came to do the estimate did such a good job explaining the work they would do, giving us options where it made sense to do so (insulate above the attic? What type of insulation?) and being transparent about the whole process. We were not disappointed, the work was beautifully and quickly done. Would highly recommend their work.

    Adam TOTALLY flaked on me...

    I made an appointment for an estimate to get my attic insulated with these people a week ago (June 25) via the Yelp app online. "Adam" communicated with me that they would be here between 10AM and 12PM on July 2nd. I had to shuffle some appointments I had in the morning around to accommodate for this time. Well, fast forward to today (July 2nd)...I've been sitting on my butt all morning to wait for the estimator to show up. When 12:15PM rolled around, a total classic no-show. I called their office and "Adam" (I presume the same Adam I was talking with through Yelp?) acknowledged my appointment and said someone would be calling me right back... So about 20 minutes later, someone named "Reuben" called me and said, "the office made a mistake...I might be able to make it around 2.." I told him "no" as I have to be in San Francisco for an appointment at 2:30..he sounded like a broken record and kept repeating that the "office made a mistake.." I told him to just forget it, that I was going to go with another company that genuinely respected their customers and their time..(do they think people just sit around all day, that other people's time is not important?!) If you're going to flake on an estimate for a potential job, chances are high that you'll flake on the actual work, too!

    After old insulation removed. Lots of droppings.

    When the day got cold, little critters started to build their homes in my attic. Following the reviews here, we contacted AtticMaster for an inspection. Roy was our inspector and later led the clean-up team. He is professional and easy to work with. He came for a free inspection the next day and actually came back the second time since we forgot to ask for the garage attic inspection at first. The pricing was reasonable and the scheduling was easy and quick. On the day of clean-up, Roy brought a four-men team including himself. The team moved fast and finished the work in 7 hours. Throughout the day, Roy texted me with progress update and photos. Overall the work was satisfactory. I am glad to have AtticMaster to clean out our attic. A good company with hard-working and professional people. I highly recommend them.

    I was in need for insulation services for my home, and searched on Yelp for local companies. I found Attic Masters, and wrote an online inquiry from their website link provided from Yelp. Within 15 minutes, I received a phone call from a live person to ask about my insulation needs. I was able to receive an estimate online, had some communication for fine-tuning the estimate, and scheduled an appointment. When the attic professionals arrived (Roy, and two other team members), they were very careful about preparing the entry way to my attics (I have two). I appreciated that they were very clean in their work, and respected my home. I originally wanted to have insulation only, but also opted to have the attic cleaned, decontaminated, and varmint-proofed prior. It seemed to make sense to have a fresh, new space before adding new R38. The cleaning work done by Attic Masters was amazing. They found a lot of debris, unwanted material, rat droppings, and more. I have posted before and after images to better describe how meticulous their work is. Not only was I unaware of the disgusting condition in my attic, I now have a greater peace of mind knowing that above my head is a sanitary space. When the cleaning was done, I was able to take a look for myself - the attic literally looks brand new! I would highly recommend this service to anyone, and especially for homes that were built many years ago like mine. The installation of the R38 was a great choice. I have added images as well for those interested in doing this. You can see that they carefully packed the R38 edge to edge. There are no areas where there is not coverage. Currently in December our energy bill is over $400. I am confident this will drop significantly now. Overall, I am very pleased with the service, staff, and work performed. The end to end experience with Attic Masters was very professional. If you are in the market for attic cleaning, decontamination, or insulation upgrades, I highly recommend them.

Showed up about 20 min late after the assigned window, but would have been nice to update me earlier. Seems like they did a good job, took around 1-1.5 hrs, however left a lot of dust and debris after on my kitchen counter and on the bed in the bedroom after they left. They also helped me change the air filters in the heater. Addendum: upgraded to add 5 stars after they reached to to rectify the situation. Appreciate it

One big tip skip the promo emails. The deals you get by contacting them directly are much better than what's advertised in those marketing blasts. Booking and pricing experience Communication was easy and transparent. No aggressive upselling, no pressure to add unnecessary services. They also offer solid incentives if you schedule on a weekend and are flexible with payment options, which I appreciated. Service experience The crew showed up on time and finished everything efficiently in about two hours. They did not show up with flashy uniforms or branded trucks, but honestly that mattered far less than the quality of the work. They clearly knew what they were doing and moved with purpose. They went the extra mile by pulling out the dryer and cleaning it thoroughly from the inside, not just the vent line. Bathroom exhaust fans were cleaned properly as well, which is something a lot of companies rush through. Results This is a relatively newer house so there wasn't a ton of buildup, but the work was done cleanly and professionally. No mess left behind and no shortcuts taken. Final verdict If you want honest work, fair pricing, and zero sales nonsense, Duct Pros is an easy recommendation. I would book them again without hesitation.

    Shady Sales Tactics! Beware of phone calls from this company…read more I've received several calls from this company in the last few months. Their voicemails claim they've taken over for HVAC Gurus, who is no longer in business. They claim I had pre-paid HVAC Gurus $279 for an AC Tune-up and Trio is honoring Guru's contracts by performing services already paid for. Here's the problem....I have no such contract with HVAC Gurus. I once had them give me a bid on attic insulation, which I did not accept. That's the extent of my business with them. My first reaction was to find all correspondence between me and HVAC Gurus to make sure I didn't somehow sign up for something I didn't want. I also checked with my credit card company to make sure I didn't give them my CC#. After 30 minutes wasted on investigating, I found nothing. I called Trio Heating, Air & Plumbing. I explained I was getting these phone calls. I was told that Trio DID NOT buy Gurus or take over for them in any way. He said Gurus stopped doing business and their contact list was passed around. He said they got a hold of this list and they are calling people to offer them a free AC Tune-up, valued at $279, in hopes of getting them to sign up with them going forward. I called him out for the lies in the phone message, that I read to him, where it specifically I had pre-paid, as well as everything else I stated above. He changed his story. He said he had a list of pre-paid customers as well as a list of people who didn't pre-pay and somehow the lists got mixed up. After I got off the phone, I discovered a text message from Trio that said they had just called me and that they are offering the AC Tune-up free, valued at $279. This completely contradicts the message the same person had left moments prior. I called the phone number for HVAC Gurus. A recording came on that says Trio is now handling their customers. So Trio lied to me when they said they did not take over their business, but just got a hold of a list that was available to other HVAC companies. I sure hope this list of pre-paid customers that got carelessly passed around didn't include credit card numbers! They may do a good job, but shady sales tactics designed to deceive customers is a good way to get a bad review from someone who may have been interested in their services.
